+       * - provider accepts interrupt, then completes normally instead;

+     * 1. Superseded thread-state events (visits alone accumulate at multiple

+     *    those events with first-write-wins semantics, so keep-latest would
+     *    change replay outcomes for reordered items.
+     * 3. Legacy v1 thread events and their pre-migration command receipts for
+     *    threads whose v2 import completed — the v1 store is only read to
+     *    import from, and imports never re-run once transcript_imported_at is
+     *    set.
+     *
+     * VACUUM is deliberately not run here: on the synchronous driver it would
+     * block every query for minutes on a multi-GB file. The reclaimable page
+     * count is reported so the caller can surface a hint instead; freed pages

+# Orchestration V2 TODO
+
+This file tracks remaining backend-oriented V2 work. Architecture-level intent lives in
+[`docs/orchestration-v2`](../../../../docs/orchestration-v2); this file is the local
+implementation checklist for `apps/server/src/orchestration-v2`.
+
+## Current Baseline
+
+- V2 commands/events/projections are server-owned and replayable.
+- Message dispatch supports start, steer, queue, queue reorder, promote queued message to steer,
+  interrupt, and provider switch command shapes.
+- Checkpoint rollback is currently a full revert: filesystem checkpoint restore, provider thread
+  rollback, stale checkpoint marking, and later run/node `rolled_back` projection state.
+- Codex same-provider fork is lazy: `thread.fork` records lineage and pending transfer, and first
+  dispatch resolves native Codex fork. Earlier source-point forks use native `thread/fork` followed
+  by fork-local `thread/rollback`.
+- Native Codex fork-from-earlier-run has a real replay-backed test fixture:
+  `testkit/fixtures/thread_fork_native_prior_turn`.
+- Merge-back from a fork into its source thread records a `merge_back` context transfer, materializes
+  a `fork_delta_summary` context handoff, and injects that handoff into the next source-thread run.
+
+## Projection Hardening
+
+Target docs:
+
+- [`core-graph-and-data-model.md`](../../../../docs/orchestration-v2/core-graph-and-data-model.md)
+- [`thread-lineage-and-context-transfer.md`](../../../../docs/orchestration-v2/thread-lineage-and-context-transfer.md)
+- [`testing-strategy.md`](../../../../docs/orchestration-v2/testing-strategy.md)
+
+TODO:
+
+- [x] Add end-to-end projection assertions for forked threads, not only provider-context behavior.
+      The fork projection should show inherited user-visible items through the source point plus an
+      explicit fork marker.
+- [x] Decide and implement the projection representation for inherited fork history:
+      referenced lineage overlay vs physically duplicated projection items. Prefer referenced overlay
+      unless product requirements need independent editable history.
+- [x] Add local visible projection assertions to non-fork replay fixtures:
+      `visibleTurnItems` mirrors canonical local `turnItems` for simple, multi-turn, queue,
+      steering, interrupt, rollback, planning, tool, and web-search fixtures.
+- [ ] Ensure projections render rollback state consistently:
+      rolled-back runs/nodes/items, stale checkpoints, and active provider thread cursor.
+- [ ] Add projection tests for interrupt edge cases:
+      provider emits chunks after interrupt requested, provider ignores/delays interrupt, interrupt is
+      immediately followed by queue/steer/start.
+- [ ] Add projection tests for queue/steer flows:
+      queued message visibility, queue reorder, promote queued message to steer, and post-interrupt
+      dispatch visibility.
+
+## Context Transfer And Merge-Back
+
+Target docs:
+
+- [`thread-lineage-and-context-transfer.md`](../../../../docs/orchestration-v2/thread-lineage-and-context-transfer.md)
+- [`provider-switching-and-context.md`](../../../../docs/orchestration-v2/provider-switching-and-context.md)
+
+TODO:
+
+- [x] Implement merge-back from a fork into its source thread:
+      source fork point as `basePoint`, fork latest stable point as `sourcePoint`, and source-thread
+      next user message as the consuming run.
+- [x] Materialize delta context artifacts for merge-back and persist them as auditable
+      `ContextHandoff` records.
+- [x] Add replay-backed integration coverage for merge-back:
+      fork, explore in fork, merge back, then assert source provider receives only the fork delta plus
+      the new user message.
+- [ ] Implement portable context handoff for cross-provider forks and same-thread provider switches.
+- [ ] Define explicit failure states for unresolved context transfers:
+      missing source point, unsupported provider capability, context too large, source projection not
+      stable, and adapter resolution failure.
+
+## Capability And Policy Model
+
+Target docs:
+
+- [`provider-capability-system.md`](../../../../docs/orchestration-v2/provider-capability-system.md)
+- [`feature-lifecycles.md`](../../../../docs/orchestration-v2/feature-lifecycles.md)
+
+TODO:
+
+- [ ] Audit capability use against the documented nested `OrchestrationV2ProviderCapabilities`
+      shape and fill any behavior gaps.
+- [ ] Keep orchestration decisions capability/policy driven. Shared runtime code should not branch on
+      provider name except at adapter registration/resolution boundaries.
+- [ ] Make optional adapter methods impossible to call without going through a policy wrapper or a
+      capability-checked branch.
+- [ ] Add typed capability/policy errors for:
+      native fork unavailable, rollback unavailable, steering unavailable, interrupt unavailable,
+      context handoff unavailable, and weak terminal status.
+- [ ] Add capability-aware tests using real adapter/test layers at provider boundaries only. Do not mock
+      core orchestration policy.
+
+## Checkpoint And Rollback
+
+Target docs:
+
+- [`feature-lifecycles.md`](../../../../docs/orchestration-v2/feature-lifecycles.md)
+- [`core-graph-and-data-model.md`](../../../../docs/orchestration-v2/core-graph-and-data-model.md)
+
+TODO:
+
+- [ ] Document current `checkpoint.rollback` command semantics in contracts/docs as full revert:
+      filesystem restore plus provider conversation rollback.
+- [ ] Decide whether we need separate commands for conversation-only rollback and filesystem-only
+      restore. Do not add them until a real product flow needs them.
+- [ ] Add tests for rollback after fork and rollback inside fork:
+      source rollback should not corrupt child lineage, and fork rollback should not mutate source
+      provider state.
+- [ ] Validate rollback behavior when no active provider thread exists. Current behavior fails; decide
+      whether a filesystem-only rollback fallback is useful or too surprising.
+
+## Provider Switching And Second Adapter
+
+Target docs:
+
+- [`provider-switching-and-context.md`](../../../../docs/orchestration-v2/provider-switching-and-context.md)
+- [`provider-capability-system.md`](../../../../docs/orchestration-v2/provider-capability-system.md)
+- [`testing-strategy.md`](../../../../docs/orchestration-v2/testing-strategy.md)
+
+TODO:
+
+- [x] Add Claude replay fixture definitions for recorded fixtures, with TODO fixture slots that
+      reference the corresponding Codex transcripts and V2 docs.
+- [ ] Promote Claude `simple` from the replay adapter to a real `ClaudeAdapterV2` replay test:
+      live and replay both consume an injected Agent SDK `query()` async iterable.
+- [ ] Record Claude `multi_turn` from real usage and prove native session/thread continuation.
+- [ ] Record Claude `tool_call_read_only` from real usage and prove read-only tool projection without
+      approvals.
+- [ ] Keep unrecorded Claude fixtures out of `testkit/fixtures/index.ts` until each has a real
+      transcript and real adapter assertions.
+- [ ] Add the second adapter once these vv0 Claude slices are stable enough to validate
+      cross-provider behavior.
+- [ ] Use the second adapter to test:
+      cross-provider fork, same-thread provider switch, returning to a previous provider thread with
+      delta handoff, and unsupported capability fallback paths.
+
+## Subagents
+
+Target docs:
+
+- [`thread-lineage-and-context-transfer.md`](../../../../docs/orchestration-v2/thread-lineage-and-context-transfer.md)
+- [`provider-capability-system.md`](../../../../docs/orchestration-v2/provider-capability-system.md)
+
+TODO:
+
+- [x] Add provider-native subagent observation for Codex and Claude replay-backed fixtures.
+- [ ] Model native subagents and app-owned cross-provider subagents as related thread/subthread graph
+      entries with different creator/lifecycle policy.
+- [ ] Preserve native provider subagent refs where available, but do not make the app graph depend on
+      provider-native ids as primary ids.
+- [ ] Add deeper tests for subagent wait, close, result transfer, pending approvals, failed/stopped
+      tasks, and fork-from-subagent behavior.
+
+FOOD FOR THOUGHT:
+
+- Custom t3code tools/mcp_server that lets agents spawn subagents of other providers powered by the T3 Orchestrator
+
+## Debugger-Only Work
+
+- Keep debugger UI useful but temporary. Backend semantics and projections should be the source of
+  truth.
+- [x] Wire the debugger thread tree to persisted V2 shell state through websocket RPC instead of
+      debugger-local thread discovery state.
+- Continue exposing lightweight controls for new backend surfaces:
+  fork from response, new thread, full revert from user message checkpoint, merge-back, and provider
+  switch.
+- Avoid adding mock backend behavior for debugger convenience. In-memory debugger state is fine for
+  layout affordances, but backend behavior must route through V2 commands/projections.

A great plan is very detailed-intent- and implementation-wise-so that it can be handed to another engineer or agent to be implemented right away. It must be **decision complete**, where the implementer does not need to make any decisions.\n\n## Mode rules (strict)\n\nYou are in **Plan Mode** until a developer message explicitly ends it.\n\nPlan Mode is not changed by user intent, tone, or imperative language. If a user asks for execution while still in Plan Mode, treat it as a request to **plan the execution**, not perform it.\n\n## Plan Mode vs update_plan tool\n\nPlan Mode is a collaboration mode that can involve requesting user input and eventually issuing a `<proposed_plan>` block.\n\nSeparately, `update_plan` is a checklist/progress/TODOs tool; it does not enter or exit Plan Mode. Do not confuse it with Plan mode or try to use it while in Plan mode. If you try to use `update_plan` in Plan mode, it will return an error.\n\n## Execution vs. mutation in Plan Mode\n\nYou may explore and execute **non-mutating** actions that improve the plan. You must not perform **mutating** actions.\n\n### Allowed (non-mutating, plan-improving)\n\nActions that gather truth, reduce ambiguity, or validate feasibility without changing repo-tracked state. Examples:\n\n* Reading or searching files, configs, schemas, types, manifests, and docs\n* Static analysis, inspection, and repo exploration\n* Dry-run style commands when they do not edit repo-tracked files\n* Tests, builds, or checks that may write to caches or build artifacts (for example, `target/`, `.cache/`, or snapshots) so long as they do not edit repo-tracked files\n\n### Not allowed (mutating, plan-executing)\n\nActions that implement the plan or change repo-tracked state. Examples:\n\n* Editing or writing files\n* Running formatters or linters that rewrite files\n* Applying patches, migrations, or codegen that updates repo-tracked files\n* Side-effectful commands whose purpose is to carry out the plan rather than refine it\n\nWhen in doubt: if the action would reasonably be described as \"doing the work\" rather than \"planning the work,\" do not do it.\n\n## PHASE 1 - Ground in the environment (explore first, ask second)\n\nBegin by grounding yourself in the actual environment. Eliminate unknowns in the prompt by discovering facts, not by asking the user. Resolve all questions that can be answered through exploration or inspection. Identify missing or ambiguous details only if they cannot be derived from the environment. Silent exploration between turns is allowed and encouraged.\n\nBefore asking the user any question, perform at least one targeted non-mutating exploration pass (for example: search relevant files, inspect likely entrypoints/configs, confirm current implementation shape), unless no local environment/repo is available.\n\nException: you may ask clarifying questions about the user's prompt before exploring, ONLY if there are obvious ambiguities or contradictions in the prompt itself. However, if ambiguity might be resolved by exploring, always prefer exploring first.\n\nDo not ask questions that can be answered from the repo or system (for example, \"where is this struct?\" or \"which UI component should we use?\" when exploration can make it clear). Only ask once you have exhausted reasonable non-mutating exploration.\n\n## PHASE 2 - Intent chat (what they actually want)\n\n* Keep asking until you can clearly state: goal + success criteria, audience, in/out of scope, constraints, current state, and the key preferences/tradeoffs.\n* Bias toward questions over guessing: if any high-impact ambiguity remains, do NOT plan yet-ask.\n\n## PHASE 3 - Implementation chat (what/how we'll build)\n\n* Once intent is stable, keep asking until the spec is decision complete: approach, interfaces (APIs/schemas/I/O), data flow, edge cases/failure modes, testing + acceptance criteria, rollout/monitoring, and any migrations/compat constraints.\n\n## Asking questions\n\nCritical rules:\n\n* Strongly prefer using the `request_user_input` tool to ask any questions.\n* Offer only meaningful multiple-choice options; don't include filler choices that are obviously wrong or irrelevant.\n* In rare cases where an unavoidable, important question can't be expressed with reasonable multiple-choice options (due to extreme ambiguity), you may ask it directly without the tool.\n\nYou SHOULD ask many questions, but each question must:\n\n* materially change the spec/plan, OR\n* confirm/lock an assumption, OR\n* choose between meaningful tradeoffs.\n* not be answerable by non-mutating commands.\n\nUse the `request_user_input` tool only for decisions that materially change the plan, for confirming important assumptions, or for information that cannot be discovered via non-mutating exploration.\n\n## Two kinds of unknowns (treat differently)\n\n1. **Discoverable facts** (repo/system truth): explore first.\n\n   * Before asking, run targeted searches and check likely sources of truth (configs/manifests/entrypoints/schemas/types/constants).\n   * Ask only if: multiple plausible candidates; nothing found but you need a missing identifier/context; or ambiguity is actually product intent.\n   * If asking, present concrete candidates (paths/service names) + recommend one.\n   * Never ask questions you can answer from your environment (e.g., \"where is this struct\").\n\n2. **Preferences/tradeoffs** (not discoverable): ask early.\n\n   * These are intent or implementation preferences that cannot be derived from exploration.\n   * Provide 2-4 mutually exclusive options + a recommended default.\n   * If unanswered, proceed with the recommended option and record it as an assumption in the final plan.\n\n## Finalization rule\n\nOnly output the final plan when it is decision complete and leaves no decisions to the implementer.\n\nWhen you present the official plan, wrap it in a `<proposed_plan>` block so the client can render it specially:\n\n1) The opening tag must be on its own line.\n2) Start the plan content on the next line (no text on the same line as the tag).\n3) The closing tag must be on its own line.\n4) Use Markdown inside the block.\n5) Keep the tags exactly as `<proposed_plan>` and `</proposed_plan>` (do not translate or rename them), even if the plan content is in another language.\n\nExample:\n\n<proposed_plan>\nplan content\n</proposed_plan>\n\nplan content should be human and agent digestible. The final plan must be plan-only and include:\n\n* A clear title\n* A brief summary section\n* Important changes or additions to public APIs/interfaces/types\n* Test cases and scenarios\n* Explicit assumptions and defaults chosen where needed\n\nDo not ask \"should I proceed?\" in the final output. The user can easily switch out of Plan mode and request implementation if you have included a `<proposed_plan>` block in your response. Alternatively, they can decide to stay in Plan mode and continue refining the plan.\n\nOnly produce at most one `<proposed_plan>` block per turn, and only when you are presenting a complete spec.\n</collaboration_mode>","model":"gpt-5.4","reasoning_effort":"medium"}},"approvalsReviewer":"user"}}}

A great plan is very detailed-intent- and implementation-wise-so that it can be handed to another engineer or agent to be implemented right away. It must be **decision complete**, where the implementer does not need to make any decisions.\n\n## Mode rules (strict)\n\nYou are in **Plan Mode** until a developer message explicitly ends it.\n\nPlan Mode is not changed by user intent, tone, or imperative language. If a user asks for execution while still in Plan Mode, treat it as a request to **plan the execution**, not perform it.\n\n## Plan Mode vs update_plan tool\n\nPlan Mode is a collaboration mode that can involve requesting user input and eventually issuing a `<proposed_plan>` block.\n\nSeparately, `update_plan` is a checklist/progress/TODOs tool; it does not enter or exit Plan Mode. Do not confuse it with Plan mode or try to use it while in Plan mode. If you try to use `update_plan` in Plan mode, it will return an error.\n\n## Execution vs. mutation in Plan Mode\n\nYou may explore and execute **non-mutating** actions that improve the plan. You must not perform **mutating** actions.\n\n### Allowed (non-mutating, plan-improving)\n\nActions that gather truth, reduce ambiguity, or validate feasibility without changing repo-tracked state. Examples:\n\n* Reading or searching files, configs, schemas, types, manifests, and docs\n* Static analysis, inspection, and repo exploration\n* Dry-run style commands when they do not edit repo-tracked files\n* Tests, builds, or checks that may write to caches or build artifacts (for example, `target/`, `.cache/`, or snapshots) so long as they do not edit repo-tracked files\n\n### Not allowed (mutating, plan-executing)\n\nActions that implement the plan or change repo-tracked state. Examples:\n\n* Editing or writing files\n* Running formatters or linters that rewrite files\n* Applying patches, migrations, or codegen that updates repo-tracked files\n* Side-effectful commands whose purpose is to carry out the plan rather than refine it\n\nWhen in doubt: if the action would reasonably be described as \"doing the work\" rather than \"planning the work,\" do not do it.\n\n## PHASE 1 - Ground in the environment (explore first, ask second)\n\nBegin by grounding yourself in the actual environment. Eliminate unknowns in the prompt by discovering facts, not by asking the user. Resolve all questions that can be answered through exploration or inspection. Identify missing or ambiguous details only if they cannot be derived from the environment. Silent exploration between turns is allowed and encouraged.\n\nBefore asking the user any question, perform at least one targeted non-mutating exploration pass (for example: search relevant files, inspect likely entrypoints/configs, confirm current implementation shape), unless no local environment/repo is available.\n\nException: you may ask clarifying questions about the user's prompt before exploring, ONLY if there are obvious ambiguities or contradictions in the prompt itself. However, if ambiguity might be resolved by exploring, always prefer exploring first.\n\nDo not ask questions that can be answered from the repo or system (for example, \"where is this struct?\" or \"which UI component should we use?\" when exploration can make it clear). Only ask once you have exhausted reasonable non-mutating exploration.\n\n## PHASE 2 - Intent chat (what they actually want)\n\n* Keep asking until you can clearly state: goal + success criteria, audience, in/out of scope, constraints, current state, and the key preferences/tradeoffs.\n* Bias toward questions over guessing: if any high-impact ambiguity remains, do NOT plan yet-ask.\n\n## PHASE 3 - Implementation chat (what/how we'll build)\n\n* Once intent is stable, keep asking until the spec is decision complete: approach, interfaces (APIs/schemas/I/O), data flow, edge cases/failure modes, testing + acceptance criteria, rollout/monitoring, and any migrations/compat constraints.\n\n## Asking questions\n\nCritical rules:\n\n* Strongly prefer using the `request_user_input` tool to ask any questions.\n* Offer only meaningful multiple-choice options; don't include filler choices that are obviously wrong or irrelevant.\n* In rare cases where an unavoidable, important question can't be expressed with reasonable multiple-choice options (due to extreme ambiguity), you may ask it directly without the tool.\n\nYou SHOULD ask many questions, but each question must:\n\n* materially change the spec/plan, OR\n* confirm/lock an assumption, OR\n* choose between meaningful tradeoffs.\n* not be answerable by non-mutating commands.\n\nUse the `request_user_input` tool only for decisions that materially change the plan, for confirming important assumptions, or for information that cannot be discovered via non-mutating exploration.\n\n## Two kinds of unknowns (treat differently)\n\n1. **Discoverable facts** (repo/system truth): explore first.\n\n   * Before asking, run targeted searches and check likely sources of truth (configs/manifests/entrypoints/schemas/types/constants).\n   * Ask only if: multiple plausible candidates; nothing found but you need a missing identifier/context; or ambiguity is actually product intent.\n   * If asking, present concrete candidates (paths/service names) + recommend one.\n   * Never ask questions you can answer from your environment (e.g., \"where is this struct\").\n\n2. **Preferences/tradeoffs** (not discoverable): ask early.\n\n   * These are intent or implementation preferences that cannot be derived from exploration.\n   * Provide 2-4 mutually exclusive options + a recommended default.\n   * If unanswered, proceed with the recommended option and record it as an assumption in the final plan.\n\n## Finalization rule\n\nOnly output the final plan when it is decision complete and leaves no decisions to the implementer.\n\nWhen you present the official plan, wrap it in a `<proposed_plan>` block so the client can render it specially:\n\n1) The opening tag must be on its own line.\n2) Start the plan content on the next line (no text on the same line as the tag).\n3) The closing tag must be on its own line.\n4) Use Markdown inside the block.\n5) Keep the tags exactly as `<proposed_plan>` and `</proposed_plan>` (do not translate or rename them), even if the plan content is in another language.\n\nExample:\n\n<proposed_plan>\nplan content\n</proposed_plan>\n\nplan content should be human and agent digestible. The final plan must be plan-only and include:\n\n* A clear title\n* A brief summary section\n* Important changes or additions to public APIs/interfaces/types\n* Test cases and scenarios\n* Explicit assumptions and defaults chosen where needed\n\nDo not ask \"should I proceed?\" in the final output. The user can easily switch out of Plan mode and request implementation if you have included a `<proposed_plan>` block in your response. Alternatively, they can decide to stay in Plan mode and continue refining the plan.\n\nOnly produce at most one `<proposed_plan>` block per turn, and only when you are presenting a complete spec.\n</collaboration_mode>","model":"gpt-5.4","reasoning_effort":"medium"}},"approvalsReviewer":"user"}}}

Add a fixture loader module, likely `src/replayFixtures.ts`.\n2. Parse NDJSON fixtures with:\n   - first line: `transcript_start`\n   - remaining lines: replay entries already compatible with `CodexAppServerReplayEntry`\n3. Convert each file into `CodexAppServerReplayTranscript`.\n4. Validate all lines through Effect Schema, returning schema-serializable errors with file path, line number, scenario, and parse/schema cause.\n5. Export fixture helpers from `package.json` as `./replay-fixtures`.\n\n## Public API\nAdd:\n```ts\nloadReplayFixture(path: string): Effect.Effect<CodexAppServerReplayTranscript, ReplayFixtureError>\nloadReplayFixtures(dir: string): Effect.Effect<ReadonlyArray<CodexAppServerReplayTranscript>, ReplayFixtureError>\n```\n\nAdd error types:\n```ts\nReplayFixtureReadError\nReplayFixtureJsonParseError\nReplayFixtureSchemaError\nReplayFixtureEmptyError\nReplayFixtureMissingTranscriptStartError\n```\n\n## Tests\nAdd tests covering:\n1. `simple.ndjson` loads into a valid transcript.\n2. Loaded `simple.ndjson` replays successfully through `layerReplay`.\n3. Malformed JSON reports file and line number.\n4. Missing `transcript_start` fails deterministically.\n5. Invalid entry shape fails schema validation.\n6. Fixture loading preserves entry order exactly.\n\n## Determinism Rules\n1. Do not rewrite existing fixture contents during replay.\n2. Keep normalization limited to existing replay comparison logic.\n3. Fixture loader must not depend on wall-clock time, current cwd, network, or process environment except the explicit file path input.\n4. Fixture order from directory loading should be lexicographic by filename.\n\n## Verification\nRun before completion:\n```sh\nbun fmt\nbun lint\nbun typecheck\nbun run test\n```\n\n## Assumptions\n1. Existing `test/fixtures/codex-app-server-probes/*.ndjson` files are the canonical initial deterministic fixture corpus.\n2. The current replay engine remains responsible for protocol-level matching.\n3. Fixture support is package-local and should not introduce runtime logic into contracts/shared packages.\n"},"threadId":"019db22b-08cd-7e12-b967-cf6ab32dd408","turnId":"019db22b-08d6-7bb3-9b7d-2ae5b8661a04"}}}

Using the `@cursor/sdk` TypeScript or Python packages, you control this flow as follows [3][1]:\n\n- Plan creation: Set `mode=\"plan\"` in `Agent.create` or `agent.send` to trigger plan-oriented output [1].\n- Record: You must manually record these events via the SDK's streaming interface (e.g., `run.stream()` in TypeScript or `on_delta`/`on_step` callbacks in Python) [4][1].\n- Replay: Replaying requires consuming these stored event logs and re-initiating the agent state via `Agent.resume(agentId)` [5][4][1].\n\nThird-party MCP orchestrators provide ready-made tools like `propose_plan` and `confirm_plan` to automate this [2]. These tools handle the persistence of plan states and approvals in an external JSON file, allowing you to gate execution until the plan is confirmed [2].\n\nHighlights:\n<result id=\"1\">\n<title>Cursor Python SDK | Cursor Documentation</title>\n<url>https://cursor.com/docs/sdk/python</url>\n<content>The async client mirrors the\n[...]\nsurface and is recommended for servers, bots, and\n[...]\ncursor_sdk\n[...]\n### Conversation mode\n[...]\nPass `mode=\"plan\"` or `mode=\"agent\"` to control whether a run explores and plans first or implements changes directly.

Project structure overview\n\n| Path | Role |\n|---|---|\n| `README.md` | Project title placeholder |\n| `.git/` | Initial commit with README only |\n| *(everything else)* | **Does not exist** |\n\nExpected structure for the task implied by the name (not yet present):\n\n```\nsrc/\n  orchestrator/       # plan lifecycle, subagent coordination\n  cursor-sdk/         # Agent.create, run.stream(), Agent.resume()\n  record/             # event capture during propose_plan\n  replay/             # fixture playback for tests\nfixtures/\n  proposed_plan/      # recorded plan JSON + SDK event streams\ntests/\n  replay/             # deterministic replay tests\n```\n\n---\n\n## 5. Current gaps for deterministic replay fixtures\n\nBecause there is no code, **all** of the following are gaps:\n\n1. **Event schema** — No type for `proposed_plan` or recorded SDK events (`SDKMessage`, tool calls, deltas).\n2. **Recorder** — No hook on agent streaming (`run.stream()`, `on_delta`, `on_step`) to persist events.\n3. **Fixture format** — No JSON/YAML convention for plans + event sequences + metadata (model, mode, cwd).\n4. **Replayer** — No substitute transport that feeds recorded events instead of live SDK calls.\n5. **Determinism controls** — No fixed clocks, idempotency keys, or stripped nondeterministic fields (timestamps, IDs).\n6. **Test harness** — No assertions comparing replay output to expected snapshots.\n7. **Orchestrator integration** — No `propose_plan` → `confirm_plan` → `execute_plan` flow to record.\n\n---\n\n## 6. Types/interfaces that would need extension\n\n**None exist in this repo.** Based on the task name and typical Cursor SDK + orchestrator patterns, you would likely need:\n\n```typescript\n// Hypothetical — NOT in codebase\n\ninterface ProposedPlan {\n  id: string;\n  goal: string;\n  subagents: SubagentSpec[];\n  // ...\n}\n\ninterface RecordedRun {\n  mode: 'plan' | 'agent';\n  agentId?: string;\n  events: SDKMessage[];  // from run.stream()\n  proposedPlan?: ProposedPlan;\n  recordedAt: string;\n}\n\ninterface ReplayFixture {\n  name: string;\n  input: { prompt: string; mode: 'plan' };\n  recorded: RecordedRun;\n  expected?: { finalStatus: string; planHash?: string };\n}\n\ninterface RecordReplayTransport {\n  record(run: AgentRun): AsyncIterable<SDKMessage>;\n  replay(fixture: ReplayFixture): AsyncIterable<SDKMessage>;\n}\n```\n\nPublic Cursor SDK concepts relevant here (external, not in repo):\n\n- `run.stream()` → normalized `SDKMessage` events (stable replay surface)\n- `Agent.resume(agentId)` → reconnect to persisted agents\n- `mode: \"plan\"` → plan-mode runs\n- Persisted replay reconstructs conversation from `SDKMessage` streams\n\n---\n\n## 7. Suggested integration points (when code is added)\n\nSince there is no code to anchor to, these are **architectural integration points** aligned with the task name:\n\n### A. SDK stream boundary (primary record point)\n\nWrap `Agent.create()` / `run.stream()`:\n\n```\nLive:  prompt → Agent.create → run.stream() → [RECORDER] → consumer\nReplay: fixture → [REPLAYER] → consumer (same interface as stream)\n```\n\nRecord every `SDKMessage`; normalize timestamps/IDs before writing fixtures.\n\n### B. Orchestrator plan lifecycle\n\nIf following a propose → confirm → execute model:\n\n| Phase | Record | Replay |\n|---|---|---|\n| `propose_plan` | Full plan JSON + planning stream | Feed recorded plan stream; skip LLM |\n| `confirm_plan` | Approval metadata | Inject fixed approval |\n| `execute_plan` | Per-subagent streams | Replay subagent fixtures in parallel |\n\n### C. Transport abstraction\n\n```typescript\ninterface AgentTransport {\n  create(options: CreateOptions): Promise<AgentHandle>;\n  stream(handle: AgentHandle): AsyncIterable<SDKMessage>;\n}\n\nclass LiveSdkTransport implements AgentTransport { /* @cursor/sdk */ }\nclass FixtureReplayTransport implements AgentTransport { /* read fixtures/ */ }\n```\n\nTests inject `FixtureReplayTransport`; production uses `LiveSdkTransport`.\n\n### D. Fixture layout (suggested)\n\n```\nfixtures/\n  proposed_plan/\n    simple-refactor/\n      meta.json           # mode, model, cwd\n      plan.json           # proposed plan artifact\n      events.ndjson       # one SDKMessage per line\n      expected.json       # optional assertions\n```\n\n### E. Determinism checklist\n\n- Strip or normalize: `timestamp`, `runId`, `agentId`, token counts\n- Use stable ordering for parallel subagent events (e.g. sort by `label` + `sequence`)\n- Fixed `idempotency_key` on sends\n- Mock filesystem/git side effects in replay mode\n\n---\n\n## 8. What you can do next\n\nThis workspace has nothing to extend yet. To proceed you would need either:\n\n1. **The parent `t3-orchestrator-v2` repo** cloned or copied into this workspace, or  \n2. **Agent mode** to scaffold the recorder/replayer/fixture layout from scratch.\n\nIf you have the orchestrator source elsewhere, point me at that repo (or switch to Agent mode with it checked out) and I can map concrete files, existing types, and exact hook points instead of this inferred architecture."}}],"agentId":"95b8b4ba-cc91-4455-9389-9729e569f76b","isBackground":false,"durationMs":45981,"backgroundReason":"unspecified"}}},"modelCallId":"12792358-9978-4430-839d-d1aa84ab7471-0-yjwv"}}}

This plan introduces the minimum structure to **record** plan-mode SDK streams and **replay** them as fixtures for deterministic tests.\n\n## Architecture\n\n```mermaid\nflowchart LR\n  subgraph live [Live mode]\n    Prompt --> LiveTransport\n    LiveTransport --> SDK[\"Cursor Agent SDK\"]\n    SDK --> Recorder\n    Recorder --> Consumer\n    Recorder --> FixtureFile\n  end\n\n  subgraph replay [Replay mode]\n    FixtureFile2[Fixture file] --> ReplayTransport\n    ReplayTransport --> Consumer2[Same consumer code]\n  end\n```\n\n**Key idea:** Orchestrator code consumes `AsyncIterable<SDKMessage>` from a transport interface; production uses live SDK, tests use fixture replay.\n\n## 1. Define core types\n\nAdd [`src/replay/types.ts`](src/replay/types.ts):\n\n- `ProposedPlanFixture` — `{ name, input: { prompt, mode: \"plan\" }, events: SDKMessage[], plan?: unknown, meta: { model?, cwd? } }`\n- `AgentTransport` — `{ create(opts), stream(handle): AsyncIterable<SDKMessage> }`\n- `RecordOptions` / `ReplayOptions` — fixture path, normalize flag\n\nReuse SDK message shapes from `@cursor/agent-sdk` (or a thin local mirror) so fixtures stay aligned with `run.stream()` output.\n\n## 2. Fixture format and layout\n\n```\nfixtures/proposed_plan/\n  <case-name>/\n    meta.json      # input prompt, mode, model, cwd\n    events.ndjson  # one SDKMessage per line (post-normalization)\n    plan.json      # extracted proposed plan artifact (optional convenience)\n    expected.json  # optional assertions (status, plan hash, key fields)\n```\n\n- NDJSON keeps diffs readable and supports streaming replay.\n- Commit normalized fixtures only (no secrets, no absolute paths).\n\n## 3. Normalization for determinism\n\nAdd [`src/replay/normalize.ts`](src/replay/normalize.ts) to strip or replace volatile fields before write/compare:\n\n- Timestamps, run/agent IDs, token counts, latency fields\n- Sort parallel sub-events by stable key (`type` + `sequence` or `label`)\n- Replace cwd/home with placeholders (e.g. `$WORKSPACE`)\n\nApply normalization in both **recorder** (on write) and **test assertions** (on compare).\n\n## 4. Implement recorder\n\nAdd [`src/replay/recorder.ts`](src/replay/recorder.ts):\n\n- Wrap live `AgentTransport.stream()` and tee events to consumer + buffer\n- On stream end, extract `proposed_plan` payload from terminal plan message(s)\n- Write fixture directory via `writeFixture(name, data)`\n\nCLI entrypoint [`src/cli/record-fixture.ts`](src/cli/record-fixture.ts):\n\n```bash\npnpm record-fixture --name simple-refactor --prompt \"...\" --mode plan\n```\n\n## 5. Implement replay transport\n\nAdd [`src/replay/replay-transport.ts`](src/replay/replay-transport.ts):\n\n- Load fixture by name/path\n- Yield `events.ndjson` lines as `SDKMessage` with configurable tick delay (default 0)\n- Implement `AgentTransport` so orchestrator plan flow is unchanged\n\nWire via env or factory in [`src/transport/index.ts`](src/transport/index.ts):\n\n```typescript\nexport function createTransport(): AgentTransport {\n  return process.env.REPLAY_FIXTURE\n    ? new ReplayTransport(process.env.REPLAY_FIXTURE)\n    : new LiveSdkTransport();\n}\n```\n\n## 6. Orchestrator hook: `proposed_plan`\n\nAdd [`src/orchestrator/propose-plan.ts`](src/orchestrator/propose-plan.ts):\n\n1. `createTransport()` → `create({ mode: \"plan\", prompt })`\n2. Consume stream until plan-complete message\n3. Return parsed plan + raw events (for optional inline recording in dev)\n\nThis is the single integration point both live and replay modes share.\n\n## 7. Deterministic tests\n\nAdd [`tests/replay/proposed-plan.test.ts`](tests/replay/proposed-plan.test.ts):\n\n- Set `REPLAY_FIXTURE=fixtures/proposed_plan/simple-refactor`\n- Run `proposePlan(prompt)` and assert:\n  - Stable plan hash or snapshot of normalized `plan.json`\n  - Expected status from `expected.json`\n- Add one golden fixture recorded from a real run, then lock behavior\n\nUse Vitest (or project-standard runner) with `fixtures/` as test data.\n\n## 8. Deliverables (minimal scope)\n\n| File | Purpose |\n|------|---------|\n| `src/replay/types.ts` | Shared fixture + transport types |\n| `src/replay/normalize.ts` | Deterministic field stripping |\n| `src/replay/recorder.ts` | Live capture → fixture |\n| `src/replay/replay-transport.ts` | Fixture → stream |\n| `src/transport/live-sdk-transport.ts` | Thin SDK wrapper |\n| `src/orchestrator/propose-plan.ts` | Plan-mode orchestration |\n| `src/cli/record-fixture.ts` | One-shot recording CLI |\n| `fixtures/proposed_plan/simple-refactor/` | Seed fixture |\n| `tests/replay/proposed-plan.test.ts` | Replay regression test |\n\n## Success criteria\n\n- Same orchestrator code path works in live and replay modes.\n- Re-running replay tests produces identical normalized plan output across machines.\n- New fixtures can be recorded with one CLI command and committed as NDJSON + JSON.\n"}},"modelCallId":"12792358-9978-4430-839d-d1aa84ab7471-2-z9b0"}}}

Implement recorder\n\nAdd [`src/replay/recorder.ts`](src/replay/recorder.ts):\n\n- Wrap live `AgentTransport.stream()` and tee events to consumer + buffer\n- On stream end, extract `proposed_plan` payload from terminal plan message(s)\n- Write fixture directory via `writeFixture(name, data)`\n\nCLI entrypoint [`src/cli/record-fixture.ts`](src/cli/record-fixture.ts):\n\n```bash\npnpm record-fixture --name simple-refactor --prompt \"...\" --mode plan\n```\n\n## 5. Implement replay transport\n\nAdd [`src/replay/replay-transport.ts`](src/replay/replay-transport.ts):\n\n- Load fixture by name/path\n- Yield `events.ndjson` lines as `SDKMessage` with configurable tick delay (default 0)\n- Implement `AgentTransport` so orchestrator plan flow is unchanged\n\nWire via env or factory in [`src/transport/index.ts`](src/transport/index.ts):\n\n```typescript\nexport function createTransport(): AgentTransport {\n  return process.env.REPLAY_FIXTURE\n    ? new ReplayTransport(process.env.REPLAY_FIXTURE)\n    : new LiveSdkTransport();\n}\n```\n\n## 6. Orchestrator hook: `proposed_plan`\n\nAdd [`src/orchestrator/propose-plan.ts`](src/orchestrator/propose-plan.ts):\n\n1. `createTransport()` → `create({ mode: \"plan\", prompt })`\n2.

This plan introduces the minimum structure to **record** plan-mode SDK streams and **replay** them as fixtures for deterministic tests.\n\n## Architecture\n\n```mermaid\nflowchart LR\n  subgraph live [Live mode]\n    Prompt --> LiveTransport\n    LiveTransport --> SDK[\"Cursor Agent SDK\"]\n    SDK --> Recorder\n    Recorder --> Consumer\n    Recorder --> FixtureFile\n  end\n\n  subgraph replay [Replay mode]\n    FixtureFile2[Fixture file] --> ReplayTransport\n    ReplayTransport --> Consumer2[Same consumer code]\n  end\n```\n\n**Key idea:** Orchestrator code consumes `AsyncIterable<SDKMessage>` from a transport interface; production uses live SDK, tests use fixture replay.\n\n## 1. Define core types\n\nAdd [`src/replay/types.ts`](src/replay/types.ts):\n\n- `ProposedPlanFixture` — `{ name, input: { prompt, mode: \"plan\" }, events: SDKMessage[], plan?: unknown, meta: { model?, cwd? } }`\n- `AgentTransport` — `{ create(opts), stream(handle): AsyncIterable<SDKMessage> }`\n- `RecordOptions` / `ReplayOptions` — fixture path, normalize flag\n\nReuse SDK message shapes from `@cursor/agent-sdk` (or a thin local mirror) so fixtures stay aligned with `run.stream()` output.\n\n## 2. Fixture format and layout\n\n```\nfixtures/proposed_plan/\n  <case-name>/\n    meta.json      # input prompt, mode, model, cwd\n    events.ndjson  # one SDKMessage per line (post-normalization)\n    plan.json      # extracted proposed plan artifact (optional convenience)\n    expected.json  # optional assertions (status, plan hash, key fields)\n```\n\n- NDJSON keeps diffs readable and supports streaming replay.\n- Commit normalized fixtures only (no secrets, no absolute paths).\n\n## 3.

+# Continued Native Subagent

+  Turn 1: spawn one subagent
+    |
+    +-- spawnAgent
+          |
+          v

+        Child app thread / Codex thread B
+          Turn 2: continuation prompt
+          Assistant: continued subagent response
+```
+
+The original parent `subagent` item represents only the spawn lifecycle. It must
+remain completed with the first result while the child thread accumulates later
+conversation turns.

+# Native Fork Continuation Fixture
+
+This fixture records a provider-native fork followed by two turns on the fork.
+It verifies that:
+
+1. The fork inherits conversation context from its source.
+2. Context introduced on the fork remains available on later fork turns.
+3. The final recall prompt does not contain either marker, so the response must
+   come from provider conversation state.
+
+Both `codex_transcript.ndjson` and `claude_transcript.ndjson` record the same
+logical scenario using each provider's native thread or session mechanism.
+
+## Conversation Graph
+
+```text
+Source provider thread
+|
++-- Turn 1
+|   User: remember source-marker-7Q9V
+|   Assistant: source marker stored
+|
+`-- native fork after Turn 1
+    |
+    `-- Forked provider thread
+        |
+        +-- Turn 2
+        |   User: remember fork-marker-2K4M
+        |   Assistant: fork marker stored
+        |
+        `-- Turn 3
+            User: recall both markers without restating them
+            Assistant: source-marker-7Q9V|fork-marker-2K4M
+```
+
+## Assertions
+
+- The fork has a native provider thread or session ID distinct from its source.
+- Turn 3's user prompt contains neither opaque marker.
+- Turn 3 returns the source marker first and the fork-local marker second.
+
+The providers may add whitespace around `|`; replay assertions normalize that
+formatting before comparing the semantic result.
+
+## Scope
+
+This is a provider-capability fixture. It proves native fork inheritance and
+continued fork context. It does not record or assert app-level merge-back
+behavior.

Always use `bun run test` (runs Vitest).\n\n## Project Snapshot\n\nT3 Code is a minimal web GUI for using coding agents like Codex and Claude.\n\nThis repository is a VERY EARLY WIP. Proposing sweeping changes that improve long-term maintainability is encouraged.\n\n## Core Priorities\n\n1. Performance first.\n2. Reliability first.\n3. Keep behavior predictable under load and during failures (session restarts, reconnects, partial streams).\n\nIf a tradeoff is required, choose correctness and robustness over short-term convenience.\n\n## Maintainability\n\nLong term maintainability is a core priority. If you add new functionality, first check if there is shared logic that can be extracted to a separate module. Duplicate logic across multiple files is a code smell and should be avoided. Don't be afraid to change existing code. Don't take shortcuts by just adding local logic to solve a problem.\n\n## Package Roles\n\n- `apps/server`: Node.js WebSocket server. Wraps Codex app-server (JSON-RPC over stdio), serves the React web app, and manages provider sessions.\n- `apps/web`: React/Vite UI. Owns session UX, conversation/event rendering, and client-side state. Connects to the server via WebSocket.\n- `packages/contracts`: Shared effect/Schema schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types. Keep this package schema-only — no runtime logic.\n- `packages/shared`: Shared runtime utilities consumed by both server and web. Uses explicit subpath exports (e.g. `@t3tools/shared/git`) — no barrel index.\n\n## Codex App Server (Important)\n\nT3 Code is currently Codex-first. The server starts `codex app-server` (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.\n\nHow we use it in this codebase:\n\n- Session startup/resume and turn lifecycle are brokered in `apps/server/src/codexAppServerManager.ts`.\n- Provider dispatch and thread event logging are coordinated in `apps/server/src/providerManager.ts`.\n- WebSocket server routes NativeApi methods in `apps/server/src/wsServer.ts`.\n- Web app consumes orchestration domain events via WebSocket push on channel `orchestration.domainEvent` (provider runtime activity is projected into orchestration events server-side).\n\nDocs:\n\n- Codex App Server docs: https://developers.openai.com/codex/sdk/#app-server\n\n## Reference Repos\n\n- Open-source Codex repo: https://github.com/openai/codex\n- Codex-Monitor (Tauri, feature-complete, strong reference implementation): https://github.com/Dimillian/CodexMonitor\n\nUse these as implementation references when designing protocol handling, UX flows, and operational safeguards.\n\n</INSTRUCTIONS><environment_context>\n  <cwd>/Users/julius/.t3/worktrees/codething-mvp/t3code-c1e5e1d1</cwd>\n  <shell>zsh</shell>\n  <current_date>2026-04-28</current_date>\n  <timezone>America/Los_Angeles</timezone>\n</environment_context>\n\nUser:\nFor this fork-boundary fixture, respond with exactly: fork boundary alpha\n\nAssistant:\nfork boundary alpha\n\nUser:\nRepeat the user-visible conversation so far verbatim.

+# Native Sibling Forks Fixture
+
+This fixture records two independent provider-native forks from the same source
+turn. It verifies that both forks inherit source context while keeping their
+fork-local context isolated.
+
+Both `codex_transcript.ndjson` and `claude_transcript.ndjson` record the same
+logical scenario using each provider's native thread or session mechanism.

+
+Fork B is created from the original source provider thread, not from fork A.
+
+## Assertions
+
+- Fork A and fork B have distinct native provider thread or session IDs.
+- Both fork responses contain the source marker.
+- Fork A contains its own marker and does not contain fork B's marker.
+- Fork B contains its own marker and does not contain fork A's marker.
+
+The providers may add whitespace around `|`; replay assertions normalize that
+formatting before comparing the semantic result.
+
+## Scope
+
+This is a provider-capability fixture. It proves native sibling topology,
+source-context inheritance, and branch isolation. It does not record or assert
+app-level merge-back behavior or the resulting source-thread context.

+# Merge-Back Continuation Fixture
+
+This fixture records a native fork, a fork-local delta, and an app-style
+merge-back handoff consumed by the original provider thread. A later source
+turn recalls both markers without receiving either marker in its prompt.
+
+Both provider transcripts execute the same graph.
+
+## Conversation Graph
+
+```text
+Source provider thread
+|
++-- Turn 1
+|   User: remember merge-source-4H8Q
+|   Assistant: merge source stored
+|
++-- native fork
+|   |
+|   `-- Forked provider thread
+|       `-- Turn 2
+|           User: remember merge-fork-7T2W
+|           Assistant: merge fork stored
+|
+`-- original source provider thread
+    |
+    +-- Turn 3
+    |   App input: merge_back handoff containing merge-fork-7T2W
+    |   Assistant: merge delta stored
+    |
+    `-- Turn 4
+        User: recall source and transferred markers without restating them
+        Assistant: merge-source-4H8Q|merge-fork-7T2W
+```
+
+## Assertions
+
+- The fork uses a different native provider thread or session.
+- The handoff and recall turns continue the original source provider thread.
+- The recall prompt contains neither marker.
+- The final response recalls both source and transferred fork context.
+
+The transcript records the provider-facing handoff format. The app-level
+`thread.merge_back` command and context-transfer lifecycle remain covered by
+the orchestrator integration tests.

+# Repeated Sibling Merge-Back Fixture
+
+This fixture records two independent native forks from one source turn, then
+feeds both fork deltas back into the original provider thread in sequence. A
+later source turn must recall all transferred context.
+
+Both provider transcripts execute the same graph.
+
+## Conversation Graph
+
+```text
+Source provider thread
+|
+`-- Turn 1: remember merge-sibling-source-3C7K
+    |
+    +-- native fork A
+    |   `-- Turn 2A: remember merge-sibling-first-6V2J
+    |
+    `-- native fork B
+        `-- Turn 2B: remember merge-sibling-second-9X5B
+
+Original source provider thread
+|
++-- Turn 3: consume merge-back handoff from fork A
+|   `-- Assistant: first merge delta stored
+|
++-- Turn 4: consume merge-back handoff from fork B
+|   `-- Assistant: second merge delta stored
+|
+`-- Turn 5: recall all markers without restating them
+    `-- merge-sibling-source-3C7K
+        |merge-sibling-first-6V2J
+        |merge-sibling-second-9X5B
+```
+
+## Assertions
+
+- Both forks have distinct native provider thread or session IDs.
+- Both handoffs resume the original source provider thread.
+- The final recall prompt contains none of the three markers.
+- The final response returns the source marker followed by both fork markers
+  in merge order.
+
+This proves repeated handoffs accumulate provider context. The app-level
+transfer records, merge ordering, and source/fork projections remain
+orchestrator responsibilities.

Additionally, all prices are subject to a 15% FIFA service fee at checkout.\n\n## Context\n\nThe 2026 FIFA World Cup will be the most expensive in tournament history. Dynamic pricing, three host nations, 104 matches, and record ticket demand have created a pricing environment unlike anything seen at a previous World Cup. FIFA received in excess of 500 million ticket requests for 2026, compared with fewer than 50 million combined for the 2018 and 2022 World Cups.\n\n\nREMINDER: You MUST include the sources above in your response to the user using markdown hyperlinks."}]},"parent_tool_use_id":null,"session_id":"f5ff7f51-4729-4331-93bd-416f3fdf2d19","uuid":"14e14d41-5638-4293-bc96-5b872dc25556","timestamp":"2026-05-07T01:18:56.738Z","tool_use_result":{"query":"FIFA World Cup 2026 ticket pricing","results":[{"tool_use_id":"srvtoolu_01PoQRt4QWnLhDhzXYQJqbsk","content":[{"title":"Tickets - FIFA World Cup 2026™","url":"https://www.fifa.com/en/tournaments/mens/worldcup/canadamexicousa2026/tickets"},{"title":"FIFA chief Infantino defends World Cup ticket prices | World Cup 2026 News | Al Jazeera","url":"https://www.aljazeera.com/sports/2026/5/6/fifa-chief-infantino-defends-world-cup-ticket-prices"},{"title":"World Cup 2026 tickets: Fans slam FIFA's new pricing strategy as tournament availability lingers | FOX 11 Los Angeles","url":"https://www.foxla.com/news/world-cup-2026-ticket-prices-fifa-strategy"},{"title":"Tickets now on sale for FIFA World Cup 2026™ Play-Off ...","url":"https://www.fifa.com/en/tournaments/mens/worldcup/canadamexicousa2026/articles/tickets-now-on-sale-for-play-off-tournament"},{"title":"New ticket pricing tier introduced for fans | FIFA World Cup","url":"https://www.fifa.com/en/tournaments/mens/worldcup/canadamexicousa2026/articles/fifa-world-cup-2026-new-ticket-pricing-tier"},{"title":"How expensive is a 2026 FIFA World Cup ticket? | Britannica","url":"https://www.britannica.com/question/How-expensive-is-a-2026-FIFA-World-Cup-ticket"},{"title":"Why are FIFA World Cup 2026 tickets so expensive? | World Cup 2026 News | Al Jazeera","url":"https://www.aljazeera.com/sports/2026/4/23/why-are-fifa-world-cup-2026-tickets-so-expensive"},{"title":"2026 World Cup Ticket Prices by City | The World Cup Guide","url":"https://theworldcupguide.com/2026-world-cup-ticket-prices/"},{"title":"How Much Do 2026 World Cup Tickets Cost?

- * identity pass through, matching the clients, which never collapse them.
- * Deliberate divergence from client collapse: clients fold only *adjacent*
- * lifecycle rows, so a superseded update separated from its completion by an
- * interleaved parallel call renders as its own row today, and this drop
- * removes it. Measured against a real database, that affects 1.5% of dropped
- * rows (553 of 36,581), all pure in-flight state whose final result the

- * carry a payload superset of their updates (verified across all 49,515

+## T3 Code orchestration
+
+The \`t3-code\` MCP server provides app-owned orchestration. Treat these concepts distinctly:
+
+- A delegated task/subagent is child work owned by the current thread. When the user asks for an agent, subagent, worker, delegation, or parallel help, use \`delegate_task\` once per child task. This remains true when targeting a different provider. Use \`orchestrator_capabilities\` to discover provider/model IDs, retain each returned \`taskId\`, and use \`task_status\` or \`task_cancel\` to manage it. The returned \`childThreadId\` is backing storage for the subagent; do not replace delegation with ordinary thread creation.
+- \`create_threads\` and \`t3_thread_start\` create ordinary top-level T3 conversations. Use them only when the user explicitly asks for separate/new/top-level threads or conversations. Never use them merely because the user said "subagent" or requested parallel delegated work.
+- \`schedule_task\` creates persistent recurring work in the app scheduler. Pass \`schedule\` as a structured object, never as JSON text: \`{"type":"interval","everyMs":3600000}\` for an interval, or \`{"type":"fixed_time","timeOfDay":"09:00","weekdays":[1,2,3,4,5]}\` for a wall-clock schedule. By default runs return to the current thread; set \`bindToCurrentThread=false\` only when the user wants a fresh thread for every run. After scheduling, report the returned cadence and next run time.
+
+Tool names may include an MCP prefix (for example \`mcp__t3-code__delegate_task\`); the semantics are the same. Keep polling/wait loops bounded, do not duplicate active work, and use stable \`clientRequestId\` values when retrying mutations.
+`;

+ * context in the first prompt. Keep the wrapper explicit so it cannot be

+/**
+ * The thread details panel's pull request row: what the branch's pull request is, and the one
+ * thing worth doing to it right now.
+ *
+ * The row itself opens the pull request in the right panel, exactly as it always has. Around
+ * that, the host's richer answer collapses into a single trailing slot, ranked by what unblocks
+ * the merge next: "Resolve" on conflicts, "Ready" on a draft, "Fix" under failing checks, and
+ * "Merge" only once the branch is clean and its checks pass. While checks run the slot reports
+ * that instead — a merge offered mid-run would race the very runs that gate it. Everything else
+ * the host knows (title, state, checks tally, diff size) lives in the row's tooltip, so a hover
+ * answers what previously took opening the panel.
+ *
+ * Until the detail arrives — or where pull requests are not supported at all — the row renders
+ * from the `vcs.status` summary alone, which is the plain row this panel showed before.

+# Orchestrator V2 audit — 2026-09-02
+
+The current branch has **17 confirmed findings: 14 correctness or feature-parity problems and three unbounded data-loading/transfer paths**. The performance findings establish unnecessary read/decode or transfer work, not measured latency or memory numbers. The earlier provider/history/compatibility fixes inspected in this pass remain present. Several newly found problems already existed before the latest rebases; they are not all new rebase mistakes.
+
+The most urgent findings are the existing-V2 database upgrade failure, project deletion that partially deletes or orphans threads, full-thread diff failure after the second run, OpenCode work surviving cancellation/release, and background Cursor metadata generation with unrestricted tool access. The web sidebar and attachment flows also have concrete regressions.
+
+This is an audit, not a fix batch. Product code and existing tests were left unchanged; nothing was committed or pushed. Reports and audit-only probes are inside the repository at your request. Three GPT-5.6 Sol reviewers worked with bounded concurrency; the primary agent reviewed their claims, traced cross-cutting paths, and rejected a false positive.

+Main being an ancestor does not prove parity: retained V1 implementations can be bypassed by V2 adapters and services. Likewise, a commit being an ancestor of the rebased review tip does not establish that the same main behavior was available at the original review. The classifications below follow current call paths and, where stated, the actual historical code.
+
+## Fix decisions
+
+**P1** means fix before rollout or the next substantial use of the affected path. **P2** means a confirmed, more limited behavior or scaling problem. Every row has a concrete trigger. A `YES` approves fixing that row; a `NO` accepts or defers the stated behavior. All decisions remain open; recommendations are not approvals.

+| F05 | P1                   | HTTP and live/offline CLI project removal bypass V2 thread cleanup. A V2-only populated project can be deleted without force; imported projects reject force.

+| F12 | P2                   | A transient automatic-title error is treated as successful completion after one call and clears the marker. Main retries twice before giving up.                                                                           | Missing main #8087 retry behavior.                                                                                                             | **YES:** restore bounded initial-title retries while preserving stale-request guards and final cleanup.                    |
+| F13 | P2                   | A failure that happened before a later snooze counts as an early wake, allowing automatic settlement before the requested wake time.                                                                                       | New V2 auto-settlement port omitted main's timestamp ordering rule.                                                                            | **YES:** require failure evidence newer than the snooze, with before/after cases.                                          |
+| F14 | P2 — performance     | Every nonempty checkpoint diff loads and decodes a full V2 transcript and potentially full fork ancestors.

+| F15 | P2 — performance     | Startup recovery sequentially loads full histories for every active and archived thread before command readiness, including terminal threads needing no recovery.                                                          | Older V2 scaling gap compared with main's shell/runtime-state recovery. Source-confirmed read cardinality.                                     | **YES:** select recovery candidates and load only their required runtime state.                                            |
+| F16 | P1 — performance     | HTTP snapshot failure or a warm reconnect exceeding 128 events / 1 MiB falls back to a full lifetime projection over WebSocket and clears progressive-history metadata. Healthy cold opens are bounded.                    | Missing main #8992/#9000 fallback-window invariant. Source-confirmed server-to-client path; no measured payload size.                          | **YES:** apply the existing bounded snapshot/SQL/budget path to socket fallbacks and preserve a usable history cursor.     |
+| F17 | P2                   | Mobile's active V2 assistant row bypasses its specialized Markdown renderer, losing Codex file citations/template actions. On iOS it also skips environment-aware inline image/video rendering and falls back to raw URIs. | Missing main #8584 and #9023 behavior at one actual mobile caller. Web retains the intended paths.                                             | **YES:** restore the assistant renderer, its scoped image callback, and the template action into the V2 composer.          |

+
+F04 and F05 can share a project-mutation implementation, but their transport and mixed-store failure cases need separate coverage. F06 and F07 share descendant traversal but have different failure contracts: explicit Stop should surface failure; release should be bounded and log failure. F03 must be correct before F14 optimizes its reads. No recommendation requires a particular large abstraction.

+## Intentional differences and product decisions
+
+These are separate from the 17 findings. Previously accepted architectural choices are not reopened as bugs merely because main differs.

+| D01 | Port continuation after a server update now?                | Main #9167 resumes active threads across restart. V2 intentionally withholds `serverUpdateThreadContinuation`; round 20 explicitly defers a V2 equivalent because recovery terminalizes active runs.           | **YES before claiming parity**, or explicitly keep deferred. This is documented omission, not an accidental rebase resolution.                                |
+| D02 | Resolve inherited markdown links against the source thread? | Inspectors use the row's `sourceThreadId`; normal message/plan markdown uses the active fork. The difference matters once source and fork worktrees diverge.                                                   | **Decision needed:** YES selects source ownership; NO keeps current-fork resolution. Main has no equivalent inherited-row model to decide this automatically. |
+| D03 | Keep the Cursor SDK boundary?                               | SDK auth, model discovery, approval/question capabilities, and native fork/rollback support differ from V1 ACP.                                                                                                | **Keep the previously accepted migration.** F08's background write permission loss is a separate defect.                                                      |
+| D04 | Keep the documented legacy-import scope?                    | Messages and thread metadata are imported; rich old tool/run/checkpoint/approval/plan history and native provider continuity are not. First V2 continuation uses a fresh session and bounded imported context. | **Keep the previously accepted scope**, with the migration docs and product messaging. F01 is an upgrade failure, not part of this tradeoff.                  |
+| D05 | Keep protocol V2 incompatibility?                           | Old clients/servers are rejected by protocol negotiation; the CORS protocol-header fix remains.                                                                                                                | **Keep the compatibility gate.** Deploy matching client/server versions.                                                                                      |
+| D06 | Keep bounded portable handoff summaries?                    | Ordinary portable handoffs collapse/truncate each summarized item at 240 characters; legacy-import context has a separate 32,000-character budget.                                                             | **Keep the previously accepted limit** unless fuller handoff fidelity is now required.                                                                        |
+| D07 | Keep compact mobile queue controls?                         | Mobile can reorder, promote, and cancel queued work, but does not mirror web's composer editor/thumbnails. Working/thinking presentation also differs by surface.                                              | **Keep as a surface choice.** F10's hidden persisted attachments is independent.                                                                              |

+## Checks that remain unproven
+
+| ID  | Question                                                         | What this audit establishes                                                                                                                                                                                         | Proposed decision                                                                                                                                 |
+| --- | ---------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
+| V01 | Does V2 need main's active-tool WebSocket coalescer?             | V1 #8368 coalesces stable tool updates; V2 detail streams deliver every stored event, and several adapters emit repeated full tool state. No comparable frame/byte measurement was taken.                           | **YES: measure a provider replay and set a frame/byte budget.** Do not copy main's claimed percentage to V2 or coalesce persisted events blindly. |
+| V02 | Is execution-triggered per-cwd skill refresh needed outside web? | Web requests cwd catalogs; Claude independently scans at execution. No equivalent V2 launch/reuse refresh was found for Codex/OpenCode, but no current-client failure was established.                              | **YES: add a focused stale/new-cwd scenario for CLI/mobile execution** before treating this as a confirmed missing feature.                       |
+| V03 | Do retained UI paths work in the real clients?                   | Source routing and focused logic tests cover much of the port. Sidebar hydration, file edits/rendering, visibility-lease intersection changes, and hosted project defaults lack the relevant integrated assertions. | Run targeted interaction tests with any fixes. A real web/mobile/desktop pass needs the separately required browser/simulator authorization.      |
+
+The proposed claim that "both auto-settlement settings off means all minute Git/PR work is wasted" was rejected on review. Both main and V2 still settle a **closed** PR independently of those two settings. Returning early would remove intended behavior; this is not a confirmed bug or an approved optimization.
+
+## Coverage and validation
+
+The [feature map](FEATURE-MAP.md) organizes retained, changed, missing, and deliberately deferred behavior across providers, clients, persistence, remote connections, and tooling. The [main commit/file map](main-feature-file-map.tsv) lists all 165 incoming main commits and their file comparisons. Of those, 46 touch only files identical to current main; 119 touch at least one differing file. That is a triage aid, not 165 independently verified features or proof retained code is called.
+
+The [previous-fix range diff](prior-fixes-range-diff.txt) compares 41 old fix/review commits with 38 rebased equivalents. Dropped/changed client patches were reviewed against current implementations; disappearance of a patch does not by itself mean its behavior was lost. The provider, persistence, and client reports contain the invariant-by-invariant results.
+

+
+The retained [audit probes](persistence-runtime-probes.test.ts) pass 3/3: they expect/capture the current migration failure, verify checkpoint scope reuse, and verify closed-PR settlement with the optional settings off. Run `vp test run audits/orchestrator-v2/2026-09-02/persistence-runtime-probes.test.ts` from the repo root. The exact output is in `persistence-runtime-probes.log`. These probes are separate from the product-test counts above.
+
+Suite counts include overlap between reviewers and are not a count of unique tests. Green tests do not disprove the findings: the reports identify missing scenarios, and the checkpoint happy-path fixture models a scope layout production cannot produce.
+
+No repo-wide checks, dev servers, browsers, simulators, live providers, external OpenCode calls, or production-state writes were used. The source audit covers the changed subsystems and feature families; it is not an exhaustive execution of every path in 942 changed files. Performance severity remains qualitative without a workload benchmark.

+# Feature map for the 2026-09-02 audit
+
+Frozen comparison: branch `d2f1f511f4` against main `57a66608b9`. Finding and decision IDs refer to [AUDIT.md](AUDIT.md). **Retained** means the relevant source path was traced and no discrepancy was found in this audit; it is not a guarantee for every provider/client combination. Exact source references and test cases are in the linked domain reports.
+
+The complete mechanical inventories are [942 changed files](changed-files.tsv), [332 branch commits](branch-commits.txt), [165 main commits](main-since-prior.txt), and the [main commit/file comparison](main-feature-file-map.tsv). The last file distinguishes unchanged leaf implementations from files requiring V2 behavior review. Its `review-v2-path` label describes that triage category, not a test result.

+| Feature family                              | Main behavior / V2 implementation                                                                                                                             | Audit result                                                                            |
+| ------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------- |
+| Instance registration, capabilities, models | Shared provider registry/drivers feed V2 adapters; removed custom models disappear, Claude remote manifests and bounded OpenCode version checks are retained. | Retained on inspected paths. [Provider evidence](providers.md).                         |
+| Cwd/project skills                          | Claude, Codex, and OpenCode expose cwd snapshots; web requests missing snapshots, Claude also reads skills at execution.                                      | Main execution-time refresh outside web remains unverified for Codex/OpenCode: V02.     |
+| Codex prompt content and usage              | Native image input plus generic attachment path text; live token usage and persisted terminal-omission behavior.                                              | Prior fixes retained; focused shared/adapter/projection tests passed.                   |
+| Codex feedback                              | Persistent feedback anchors, duplicate/in-flight guards, environment/thread ownership.                                                                        | Prior fixes retained on web/mobile shared command paths. [Client evidence](clients.md). |
+| Claude approvals                            | Session-only permission suggestions, abort already signaled, policy-specific tool access, questions handled in every runtime mode.                            | Prior fixes retained; focused adapter tests passed.                                     |
+| Claude questions                            | Structured/multiple questions, multi-select normalization, structured response contract.                                                                      | Prior fixes retained.                                                                   |
+| Claude plans, todos, compaction, subagents  | Stable planning item identities/lifecycle, resume and compaction controls, model propagation across native task ordering.                                     | Prior fixes retained.                                                                   |
+| Claude workspace-image reads                | Main classifies image Read input for inline preview. V2 preserves input but neither client derives a preview path.                                            | Missing main behavior: F11.                                                             |
+| OpenCode prompt admission                   | Native request/message correlation, generation-owned status reconciliation and retries, cancellation of pending initial/steer HTTP prompts.                   | Prior fixes retained; targeted tests passed.                                            |
+| OpenCode cancellation                       | Main aborts the descendant tree and reports relevant failures. V2's new descendant traversal discards failures.                                               | Partial port: F06.                                                                      |
+| OpenCode external-server teardown           | Main aborts root and descendants when releasing the session. V2 release closes its subscription only.                                                         | Missing lifecycle behavior: F07.                                                        |
+| Cursor SDK boundary                         | Native SDK replaces ACP, with different auth/model/capability support.                                                                                        | Intentional D03. Background text-generation write boundary is separately broken: F08.   |
+| Grok and generic ACP                        | Flavored ACP model selection, health and interruption controls; generic adapter/runtime support remains.                                                      | No additional source-confirmed regression found in the provider review.                 |
+| Source-control and title generation         | Main PR-linked title context and shared prompt changes remain in use. Initial title transient-error retries are absent.                                       | Retained prompts; F12 and Cursor-specific F08.                                          |

+## Persistence, thread lifecycle, and orchestration
+
+| Feature family                       | Main behavior / V2 implementation                                                                                                                | Audit result                                                                                                                                    |
+| ------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- |
+| Database upgrades                    | Numeric migration runner plus inserted main migration 044; previously applied V2 IDs were shifted.                                               | Fresh-schema tests pass, old-V2 upgrade fails: F01.                                                                                             |
+| Legacy import                        | Metadata, pins/order, snooze and PR links copied and repaired; legacy rows kept for compatibility.                                               | Prior metadata/search fixes retained. Loss of rich legacy history/native continuity is documented D04.                                          |
+| Project removal                      | Main enforces nonempty/force checks and deletes its thread representation consistently. V2 has mixed-store and transport-specific paths.         | F04 over WS; F05 over HTTP and live/offline CLI.                                                                                                |
+| Thread archive/delete visibility     | V2 lifecycle, archived shell separation, migrated ownership filters in legacy search.                                                            | Prior filtering and history visibility fixes retained. Project-level cleanup is the exception above.                                            |
+| Worktree recovery                    | Missing worktree is recreated before provider turn start. Shared Git paths preserve local-only base support.                                     | Recovery fix retained; scoped existing tests passed.                                                                                            |
+| Queue ordering/delivery              | Durable queued runs, delegated-completion priority, promote/steer/cancel controls.                                                               | Queue-order and delegated-completion tests passed. File editing is a separate client defect F09.                                                |
+| Settlement, pinning, snoozing        | V2 server sweep evaluates main's inactivity/PR rules with live/pending-work exclusions and snapshot guards.                                      | Most rules retained; failure-before-snooze ordering missing: F13. Closed-PR settlement remains intentionally active with optional settings off. |
+| Unsettled ordering                   | Stable reanchoring and shared max(created/updated/unsettled) sorting.                                                                            | Prior server and client fixes retained.                                                                                                         |
+| Recovery/outbox/receipts             | Durable event/projection/effect transactions, replayable vs process-bound effects, checkpoint wait recovery, typed command receipts.             | Focused recovery, effect worker, finalization, and runtime tests passed. Startup's query scope is overbroad: F15.                               |
+| Checkpoint capture                   | Shared deterministic scope and ordinal refs; replayable capture/finalization.                                                                    | Capture invariants retained. The diff query assumes an incompatible scope layout: F03.                                                          |
+| Checkpoint query cost                | Main queries narrow checkpoint context; V2 loads full projection.                                                                                | Confirmed data-loading regression: F14.                                                                                                         |
+| History pagination                   | V2 SQL filters the visible cohort before LIMIT, retains paired stop requests and nested fork identities, and pages to the actual end.            | Earlier fixes retained; SQL/history tests passed.                                                                                               |
+| HTTP detail and WS fallback payloads | V2 central row/byte/control-plane budgets, overflow reporting, bounded SQL window protect healthy HTTP cold opens. Socket fallbacks bypass them. | Earlier HTTP budgeting fixes retained, but failed HTTP loads and large reconnect gaps expose F16.                                               |
+| Portable provider handoffs           | V2 supports context transfer and provider changes, using bounded portable summaries and a separate legacy-import budget.                         | Documented D06; focused context-handoff tests passed. Full provider-switch/fork permutations were not live-tested.                              |
+| Delegated work                       | App-owned child tasks, durable completion transfer, parent wake/deduplication.                                                                   | Selected completion-delivery tests passed; branch-added feature rather than a direct V1-equivalence claim.                                      |
+| Scheduled tasks                      | App-owned interval/fixed-time scheduling and legacy interval compatibility.                                                                      | Existing schedule tests passed, including legacy sub-minute floor and missed-time grace. No wall-clock/live scheduler test was run.             |
+| Server update continuation           | Main's active-thread restart continuation is gated off by the V2 server descriptor.                                                              | Explicitly deferred D01, distinct from recovery correctness.                                                                                    |

+| Codex file citations, artifact templates, iOS inline media | Web still uses the directive renderer and appends chosen template prompts. Mobile bypasses its assistant helper, including its native image callback.               | F17 covers the single caller gap behind main #8584/#9023 losses. Android's custom image renderer remains wired. This is separate from selected-text inline citations above.  |
+| Activity groups and errors                                 | Failed tools remain visible; web working/thinking rows and compact native groups use different presentations.                                                       | Relevant prior fixes retained.

+| Billing/token pricing             | Cached Claude pricing, incremental transcript reader, scan-cache preservation unchanged from main; V2 usage projection retains omitted terminal values. | Main #8806/#9024/#8540 and previous V2 usage fixes retained; targeted tests passed. No confirmed token-price regression.                                  |
+| Active-stream network cost        | Several adapters emit repeated full tool state; main's semantic coalescer is absent from V2 detail delivery.                                            | V01: source exposure, no measured frame/byte regression.                                                                                                  |
+| Reconnect/fallback transfer cost  | Main preserves a bounded fallback window; V2 sends a lifetime projection after HTTP failure or an over-budget resume.                                   | Confirmed F16. Individual tool-value truncation does not bound collection cardinality.                                                                    |
+| Startup/diff database cost        | Queries read more transcript state than the operations need.                                                                                            | Confirmed F14/F15; no invented benchmark percentages.                                                                                                     |
+| Server bundle/service launch      | Both server and service-launcher entry points remain included in build configuration.                                                                   | Previous packaging fix retained; no packaging/release build run.                                                                                          |
+| Shared non-orchestration features | PR driver/cache changes, themes, editor leaf components, native build/quit/preview updates, Windows shell utilities, release/tooling changes.           | Inventoried against main. Unchanged leaf files are distinguished in the commit/file map; this audit does not claim end-to-end OS/build coverage for them. |
+
+The remaining gaps are explicit in [AUDIT.md](AUDIT.md): provider/burst performance, cwd refresh outside web, and real-client interaction. The review does not treat lack of a test, a renamed V1 component, or a deliberate V2 representation change as proof of a regression.

+# Client parity audit: orchestrator v2 rebases
+
+Audit target: `d2f1f511f4cc833bc930d6c355cd0f9b61e835a0`
+
+Upstream baseline: `57a66608b918d673eeec7e6c94ea5906b756fcd0` (verified ancestor)
+
+Prior review object: `47f5b100440591d2f49aa30cf3bb69eacae07f52`; rebased prior tip: `c1791ab2637`
+
+Scope: `apps/web`, `apps/mobile`, `packages/client-runtime`, and relevant desktop entrypoints. I read both supplied inventories, followed the affected UI actions through client-runtime commands and projections, and compared current code to the supplied upstream main object. This was a source review backed by focused existing tests. I did not use a browser, dev server, provider, or production state.
+
+## Confirmed findings
+
+All four findings below are source-confirmed. I did not reproduce them in a real client.
+
+### High: the web sidebar crashes when a listed environment has no hydrated provider config
+
+- **Current evidence:** `apps/web/src/components/Sidebar.tsx:3680-3682` and `:3789-3791` evaluate `EMPTY_PROVIDER_ENTRIES` as the fallback for a missing environment entry. The binding is declared inside `Sidebar` only at `:3997`, after the component's unconditional return at `:3996`, so it remains in the temporal dead zone for that render. The map is expected to be incomplete: `packages/client-runtime/src/state/shell.ts:421-433` adds only non-null server configs, while the sidebar builds provider maps from that result at `apps/web/src/components/Sidebar.tsx:1887-1899`.
+- **Upstream main evidence:** at `57a66608b918d673eeec7e6c94ea5906b756fcd0`, `apps/web/src/components/Sidebar.tsx:265` declares the empty map at module scope and uses it at `:3721-3722`. `git blame` attributes the misplaced current declaration to round 18 reconciliation commit `7697286069f`.
+- **Reachable trigger:** open web or desktop with a cached/disconnected, reconnecting, newly added, or otherwise not-yet-configured environment that still contributes a visible thread. Either the normal thread list or search results can take the fallback.
+- **Impact:** React render throws `ReferenceError: Cannot access 'EMPTY_PROVIDER_ENTRIES' before initialization`; the whole sidebar/client surface can fail instead of showing cached threads. Any cached shell can expose it, with disconnected/reconnecting remote environments making it especially reproducible.
+- **Minimal action:** restore the module-scope declaration from main. Add a rendered sidebar behavior test whose catalog/shell contains a visible remote thread while that environment's config atom is null, and assert that the row remains usable.
+
+### High: editing a queued web message accepts generic files, then silently omits them from the saved edit
+
+- **Current evidence:** edit mode uses the ordinary composer and its file picker remains enabled (`apps/web/src/components/chat/ChatComposer.tsx:842-855`, `:4390-4422`). Generic files are accepted into `composerDraft.files` at `:3151-3186`. `ChatView` reads those files at `apps/web/src/components/ChatView.tsx:5892-5904`, but the queued-edit branch at `:5938-5971` checks and serializes only `composerImages`; `composerFiles` does not participate in the empty-edit guard, upload list, or replacement attachment list. The shared command already supports mixed stored/upload attachments and persists them before dispatch (`packages/client-runtime/src/operations/commands.ts:213-225`, `:242-267`, `:843-857`).
+- **Related loss path:** if the queued run starts or is cancelled from another client, `apps/web/src/components/ChatView.tsx:3323-3345` treats an edit as dirty only when text changed or images exist. A file-only edit is cleared. The move helper itself can transfer files (`apps/web/src/composerDraftStore.ts:3875-3946`); the caller simply never invokes it for a file-only edit.
+- **Upstream main evidence:** v1 has no queued-message editor, but its established send invariant snapshots both images and files and runs both through attachment upload (`57a...:apps/web/src/components/ChatView.tsx:5897-5903`, `:5950-5962`). The v2 edit contract likewise explicitly accepts `UploadChatAttachment`; this is not an unsupported contract case.
+- **Reachable trigger:** while an active run has a queued follow-up, choose **Edit in the composer**, attach a PDF/video/text file, then save. With no text or retained attachment, the button appears to do nothing; with text or another attachment, the edit succeeds and the newly selected file disappears. A second client starting/cancelling the run also drops a file-only unsaved edit.
+- **Impact:** user-selected content is silently excluded from the queued message, including on remote/multiple-environment setups where queued editing is especially useful. The local draft is then cleared after the successful text/image edit.
+- **Minimal action:** feed `composerFiles` through the existing attachment-upload path and include them in the queued edit's emptiness and replacement calculations; include files in the cross-client dirty check. If generic files are intentionally unsupported for edits, hide/disable that picker during edit mode with an explicit reason instead of accepting and dropping them. Add an interaction test that edits a queued run, selects a generic file, saves, and verifies the dispatched edit contains the persisted attachment; separately exercise a file-only edit when another client removes the run and verify it is retained in the base composer.
+
+### High: mobile filters out every non-image message attachment before its file/video/PDF renderer can run
+
+- **Current evidence:** `apps/mobile/src/features/threads/ThreadFeed.tsx:1618-1626` reduces every message's attachments to `type === "image"`. The user-message and assistant-message branches still contain file and unknown renderers at `:1678-1698` and `:1774-1794`, but those branches are unreachable after the filter.
+- **Upstream main evidence:** `57a...:apps/mobile/src/features/threads/ThreadFeed.tsx:1527-1533` keeps `message.attachments ?? []`, and `:1580-1600` reaches `MessageAttachmentFile`. The image-only filter entered in round 11 reconciliation commit `0301dc423e3`; its diff changes this exact line from the complete list to the filter.
+- **Reachable trigger:** send or queue a PDF, video, text file, or other generic attachment from web or desktop, then read the message in the mobile thread feed. The projection still carries user attachments (`apps/mobile/src/lib/threadActivity.ts:1055-1077`), so this is solely a presentation loss.
+- **Impact:** mobile history makes attached files appear absent. Users cannot open the existing PDF/file preview or video flow, and cross-client conversations give conflicting accounts of what was sent. Data remains persisted, but the mobile UI hides it.
+- **Minimal action:** restore `const attachments = message.attachments ?? []`. Add a feed interaction test with a projected file/video attachment that presses the rendered row and observes the preview/video callback; do not limit the test to component props or static markup.
+
+### Medium: mobile's active v2 assistant row bypasses the specialized Markdown renderer
+
+- **Current evidence:** `AssistantMarkdownContent` still exists at `apps/mobile/src/features/threads/ThreadFeed.tsx:969-1016`. It splits artifact-template blocks, converts file citations to ordinary Markdown links, gives template cards an `onUse` action, and passes the thread's `renderImage` callback to native Markdown. The active v2 assistant branch never calls it. Instead, `:1755-1772` sends raw `message.text` directly to the generic renderers and omits `renderImage` from `SelectableMarkdownText`. `ThreadFeedProps` also has no artifact-template callback (`:232-256`), and the real `ThreadDetailScreen` call at `apps/mobile/src/features/threads/ThreadDetailScreen.tsx:683-715` supplies none.
+- **iOS media consequence:** `apps/mobile/modules/t3-markdown-text/src/SelectableMarkdownText.ios.tsx:64-80` sets the image-renderer context to `null` when the caller omits that prop. `NativeMarkdownBlock.ios.tsx:380-422` then falls back to `<Image source={{ uri: href }}>`. That fallback does not resolve a workspace-relative or host-machine path through the owning environment, cannot select the video renderer, and has no signed `media-file` resource. The omitted callback is the one that creates scoped image/video previews at `apps/mobile/src/features/threads/ThreadFeed.tsx:2342-2390`. Android's fallback Markdown path still receives the custom image renderer through `styles.renderers` (`:1364-1371`, `:1763-1771`).
+- **V2 text remains verbatim:** the Codex adapter appends `payload.delta` without conversion (`apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts:3157-3167`), chooses the provider's final `payload.item.text` at `:3683-3687`, and copies that string unchanged into both the message and assistant turn item at `:2436-2468`. Client-runtime upserts the event payload unchanged (`packages/client-runtime/src/state/orchestrationV2Projection.ts:224-225`), and mobile copies `item.text` into the feed message (`apps/mobile/src/lib/threadActivity.ts:1055-1081`). The only mobile Codex directive conversion calls are inside the bypassed `AssistantMarkdownContent`, so the trigger is real rather than already normalized upstream.
+- **Upstream main evidence:** `57a...:apps/mobile/src/features/threads/ThreadDetailScreen.tsx:623-636` appends the selected template prompt to the live composer and passes that callback at `:690-716`. Main's `ThreadFeed.tsx:1453-1455`, `:1633-1641`, and `:2698-2710` route assistant text through `AssistantMarkdownContent`, including `onUseArtifactTemplate` and `renderMarkdownImage`. The callback and active invocation were removed during the v2 reconciliation diff even though the adapter component was retained.
+- **Reachable trigger:** read a mobile v2 Codex response containing a `codex-file-citation` or `codex-artifact-template` directive. On iOS, any assistant Markdown workspace/host image or image-syntax video reaches the same bypassed call and loses environment-aware resolution.
+- **Impact:** mobile does not produce the file citation's navigable link, and artifact templates lose the **Use template** action. On iOS, assistant workspace/host images and embedded-video Markdown also fail or render through the wrong primitive. Web remains intact through `apps/web/src/components/chat/MessagesTimeline.tsx:1590-1614` and `apps/web/src/components/ChatMarkdown.tsx:2096-2109`, `:2362-2368`.
+- **Minimal action:** restore `AssistantMarkdownContent` in the current assistant-row branch, restore the `ThreadFeed` callback, and adapt main's composer-append handler to the current v2 draft setter. That one caller restoration also passes `renderMarkdownImage` on iOS. Add an integrated feed/composer behavior test that selects a template and observes the draft change, a citation press that reaches scoped file navigation, and an iOS native Markdown image/video case that observes the environment-scoped media renderer rather than the direct-URI fallback.
+
+## Intentional or established surface divergences
+
+- **Mobile queue controls remain compact.** Web exposes thumbnail rows and composer-based queued-message editing (`apps/web/src/components/chat/QueuedRunsControl.tsx:44-95`, `:331-440`). Mobile exposes environment/thread-scoped reorder, promote-to-steer, and cancel controls but no editor or thumbnails (`apps/mobile/src/features/threads/ThreadQueueControl.tsx:18-72`, `:74-149`). Neither supplied main inventory nor the v1 mobile baseline establishes queued editing as a mobile requirement, so I did not report the absence itself as a regression. The hidden persisted attachments in the feed are independent and are reported above.
+- **Desktop inherits the web client.** The only branch-vs-main desktop changes are `DesktopEnvironment.test.ts`, `tailscaleEndpointProvider.ts`, and `DesktopClientSettings.test.ts`; there is no separate desktop composer/timeline implementation to reconcile. The two web findings therefore apply to desktop's wrapped web surface as well.
+- **Working/thinking presentation differs by surface.** Web derives explicit active-tool and working/thinking rows in `apps/web/src/components/chat/MessagesTimeline.logic.ts:760-845` and `:1067-1075`; mobile folds live activity into native grouped work rows in `apps/mobile/src/lib/threadActivity.ts:798-917`. Both retain terminal failure visibility. This looks like established compact-mobile presentation, not a semantic loss.
+
+## Both-main bugs
+
+No confirmed defect in this scope is shared by current branch and the supplied main baseline. Each finding above is either introduced by the v2/reconciliation work or is specific to a branch-only feature.
+
+## Uncertainty requiring a product decision
+
+### Inherited fork markdown currently resolves against the active fork, not the row's owning thread
+
+V2 feed rows preserve `sourceThreadId` (`packages/client-runtime/src/state/threadHistoryMerge.ts:54-88`; `apps/mobile/src/lib/threadActivity.ts:1055-1077`). Inspector file navigation correctly uses that source (`apps/mobile/src/features/threads/ThreadActivityInspector.tsx:84-105`), and the web inspector fix does the same (`apps/web/src/components/chat/V2ItemInspector.tsx:132-142`). Regular timeline markdown instead receives the active route thread on web (`apps/web/src/components/chat/MessagesTimeline.tsx:684-712`, `:1590-1613`) and the active screen thread on mobile (`apps/mobile/src/features/threads/ThreadFeed.tsx:2301-2340`, `:2342-2390`). Proposed-plan timeline rows also pass only the active route thread (`apps/web/src/components/chat/MessagesTimeline.tsx:1711-1726`).
+
+This may be intentional: a fork's continuation starts from the same workspace and users may expect inherited file links to open in the current checkout. It may instead violate the prior "owning environment/thread" rule when source and fork worktrees diverge. Main v1 has no equivalent projected inherited-row model, so there is no clean parity oracle. Before changing it, decide whether inherited message/plan markdown denotes historical source state or current-fork state, then add a behavioral fork test that opens a workspace file after the two worktrees diverge and verifies the selected thread/resource.

Both existing and fresh new-thread paths seed sticky state before project/carried overrides (`apps/web/src/hooks/useHandleNewThread.ts:263-280`, `:395-414`).

+| `0e1570bde5` hosted explicit project defaults                  | **Retained, with a test gap.** Project Settings reads providers and option settings from the representative project's environment, not the absent hosted primary (`apps/web/src/components/settings/ProjectSettingsPanel.tsx:293-307`, `:424-452`). The explicit selection fans out through environment-scoped project updates to every logical-project member (`:366-400`, `:450-452`, `:860-892`). Primary-only server settings separately go inert on the hosted app (`apps/web/src/hooks/useSettings.ts:321-333`, `apps/web/src/components/settings/settingsLayout.tsx:166-217`).                               | Hosted-app detection tests passed, but there is no focused Project Settings behavior test proving that a hosted remote environment's providers populate the default-model picker and that selection dispatches to the correct environment members. Source routing is intact. |

+| `#8237` (`86c9a9288b`) mobile file/share receive         | **Partial.** The native share presentation reaches the New Task sheet (`apps/mobile/src/Stack.tsx:368-389`), the selected environment owns capability filtering and draft merge (`apps/mobile/src/features/threads/NewTaskDraftScreen.tsx:521-644`), and manual file picks reach the same draft (`:809-835`). Submission carries the attachments through environment-scoped preparation into v2 `thread.turn.start` (`:963-977`; `apps/mobile/src/features/threads/use-project-actions.ts:66-134`; `apps/mobile/src/lib/projectThreadStartTurn.ts:37-87`). Acquisition and delivery are retained; generic received files are hidden after delivery by the already-reported `ThreadFeed.tsx:1624-1626` filter.                                                                                                                                                                                                                                                                                                                                                                     |
+| `#8978` (`9bc7a56848`) upload while composing            | **Partial.** The root worker remains mounted outside composers (`apps/mobile/src/Stack.tsx:353-360`), keys transfers by environment and attachment, and updates only drafts that still own the file (`apps/mobile/src/state/composer-attachment-uploads.ts:50-125`; `apps/mobile/src/lib/composerAttachmentUploadQueue.ts:16-78`). Existing and new-task composers block connected sends until uploads are ready (`apps/mobile/src/features/threads/ThreadComposer.tsx:377-385`; `NewTaskDraftScreen.tsx:881-888`, `:1038-1048`), and v2 consumes the uploaded references. Upload/delivery is retained; post-send generic-file visibility is partial only because of the existing attachment-filter finding.                                                                                                                                                                                                                                                                                                                                                                      |
+| `#8914` (`746c932e16`) defer draft navigation            | **Retained.** Successful v2 creation clears the draft, records a replacement action, and waits until the share/submission removal guard drops before dispatching it on the next frame (`apps/mobile/src/features/threads/NewTaskDraftScreen.tsx:331-347`, `:963-1020`). Failure returns without navigation or draft clearing (`:991-999`).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
+| `#8614` (`352710d497`) offline iPhone voice              | **Retained.** Both real composers use the local voice controller and commit transcription through their existing draft setters (`apps/mobile/src/features/threads/ThreadComposer.tsx:349-385`; `NewTaskDraftScreen.tsx:318-347`). The controller snapshots owner/text/selection and blocks send while busy (`apps/mobile/src/features/voice-input/useVoiceInputController.ts:63-126`, `:199-216`); the iOS adapter prepares and transcribes on-device (`apps/mobile/src/native/voiceTranscription.ios.ts:36-97`). Its output therefore follows the normal online or outbox-backed v2 send path without a provider dependency.                                                                                                                                                                                                                                                                                                                                                                                                                                                     |
+| `#9140` (`f46a709ee4`) external Markdown/HTML/PDF        | **Retained.** Web assistant rows pass the active v2 thread and workspace to `ChatMarkdown` (`apps/web/src/components/chat/MessagesTimeline.tsx:1590-1614`), which routes outside-workspace non-media files into the scoped file panel and HTML/PDF into preview (`apps/web/src/components/ChatMarkdown.tsx:2313-2358`). Mobile link handling preserves absolute paths and scopes host PDF/media resources to the active environment/thread (`apps/mobile/src/features/threads/ThreadFeed.tsx:2250-2340`; `apps/mobile/src/features/files/filePath.ts:13-48`). Host text remains read-only in the viewers. The inherited-fork ownership question remains the separate uncertainty above.                                                                                                                                                                                                                                                                                                                                                                                           |
+| `#9143` (`d937e30759`) web viewer                        | **Retained.** The v2 right-panel surface supplies the active project environment, workspace, and thread to a stable `FilePreviewPanel` instance (`apps/web/src/components/ChatView.tsx:7287-7311`). The panel chooses video/image/HTML/PDF/Markdown/source modes, uses a sandbox for HTML, and keeps host files read-only (`apps/web/src/components/files/FilePreviewPanel.tsx:200-315`, `:947-999`, `:1159-1248`).                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |
+| `#9023` (`beae2147a94`) host-file/video streaming        | **Partial across clients.** Web/desktop v2 media resolves signed resources against the row's thread environment (`apps/web/src/components/ChatMarkdown.tsx:2016-2057`, `:2611-2693`), and Electron permits streaming plus custom-scheme media (`apps/desktop/src/electron/ElectronProtocol.ts:85-94`, `:112-134`). Mobile's scoped Markdown and file-route resource builders remain (`apps/mobile/src/features/threads/ThreadFeed.tsx:2286-2390`; `apps/mobile/src/features/files/workspaceFileAssetUrl.ts:21-40`). The file route and Android Markdown caller still reach them. The active iOS assistant caller omits `renderImage`, however, so workspace/host images and image-syntax videos fall back to a direct URI instead of these builders (`apps/mobile/src/features/threads/ThreadFeed.tsx:1755-1772`; `apps/mobile/modules/t3-markdown-text/src/NativeMarkdownBlock.ios.tsx:380-422`). Video/generic message attachments are separately blocked by the already-reported image-only filter. Both mobile losses share existing findings rather than adding another one. |
+| `#8630` (`d2042d288e`) stale writes on close             | **Retained.** Both editable source and rendered task-list surfaces use the coordinator (`apps/web/src/components/files/FilePreviewPanel.tsx:553-581`, `:610-624`, `:874-899`). Unmount/close disposes it, clears the debounce, and flushes the latest revision; if a save was already in flight, completion immediately persists the newer revision (`apps/web/src/components/files/fileSaveCoordinator.ts:21-34`, `:50-77`). The active v2 file panel unmounts through the right-panel branch at `apps/web/src/components/ChatView.tsx:7287-7313`.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |
+| `#8968` (`f2a914b858`) panel state during refresh        | **Retained.** Workspace mutations refresh data without changing the file-panel key (`apps/web/src/components/ChatView.tsx:7287-7311`). The file tree batches path deltas rather than resetting its model and suppresses replayed reveals (`apps/web/src/components/files/FileBrowserPanel.tsx:274-353`). Diff refreshes keep stable identity keys and loader callbacks while content versions change (`apps/web/src/components/DiffPanel.tsx:280-326`, `:403-435`, `:919-970`; `apps/web/src/components/diffs/AnnotatableCodeView.tsx:126-167`). This preserves expansion, search, selection, collapse, and scroll state across refresh.                                                                                                                                                                                                                                                                                                                                                                                                                                          |
+| `#8584` (`c1e70b5f8`) Codex citations/artifact templates | **Partial; new finding above.** The shared parser/template prompt helpers remain (`packages/client-runtime/src/codexMarkdownDirectives.ts:187-215`, `:308-358`; `packages/client-runtime/src/codexArtifactTemplates.ts:97-127`). Web's real v2 row still renders citations/templates and appends a chosen template to the current composer (`apps/web/src/components/chat/MessagesTimeline.tsx:1590-1614`; `apps/web/src/components/ChatView.tsx:3229-3247`). Mobile retains the adapter component but the active v2 assistant row and real screen no longer call or configure it (`apps/mobile/src/features/threads/ThreadFeed.tsx:969-1016`, `:1755-1772`; `apps/mobile/src/features/threads/ThreadDetailScreen.tsx:683-715`).                                                                                                                                                                                                                                                                                                                                                  |

+The green suites do not cover the missing-config sidebar render, generic-file queued edit, mobile non-image attachment rendering, the mobile specialized-Markdown caller regression including iOS media, visibility-lease intersection behavior, or hosted Project Settings behavior. They were not rerun during the final bounded file/media pass. React Doctor's review criteria were applied during the source review; its network-installed CLI was not run because this audit made no React edits and the user requested avoiding broad/network-heavy tooling without clear value. No browser or real-client integration pass was run, per instruction.

+Current-branch cross-cutting review, 2026-09-02
+
+Frozen branch: `d2f1f511f4cc833bc930d6c355cd0f9b61e835a0`. Main: `57a66608b918d673eeec7e6c94ea5906b756fcd0`. Read-only product review; all files in this directory are uncommitted audit artifacts.
+
+**Confirmed missed port: automatic title retries (P2).** Main `fc262f1a28` (#8087) retries `generateThreadTitle` twice using exponential backoff. The v2 replacement calls `generateThreadTitle` once (`apps/server/src/orchestration-v2/ThreadTitleRegenerationService.ts:223`) and catches non-interruption failures as a successful completion (`:236`). It then clears the title marker (`:249`); the effect worker sees success and cannot retry. Initial generation is only armed when a `titleSeed` arrives with no existing messages (`Orchestrator.ts:2915`). A transient typed provider error therefore leaves the fallback title until manual regeneration. This is distinct from preserving the final-failure cleanup behavior. The common `TextGeneration.ts:150` dispatcher does not add a retry. Recommendation: port bounded retry for initial titles and retain stale-request guards/final cleanup. Source trace confirms the missing retry; the existing failure test covers cleanup after one call, not recovery from a transient typed failure.
+
+**Explicitly deferred main feature: continue active threads after an update.** Main `5b7d72aad1` (#9167) persists continuation markers and resumes active work after server restart. Current `ServerEnvironment.ts:230` deliberately withholds `serverUpdateThreadContinuation`; `serverRuntimeStartup.ts` and `ws.ts:1647` do not implement the main marker/continuation path. The round-20 commit (`d2f1f511f4`) explicitly records that v2 recovery terminalizes runs and a v2 equivalent is still needed. Web settings and capability-gated request plumbing are present. Recommendation: make a release decision to port this or keep it deferred; do not label it an accidental conflict resolution.

+| Existing v2 database upgrade after migration renumbering | The last commit shifts old 044–052 to 045–053. Effect SQL migrator skips IDs at/below the recorded maximum; new 053 unconditionally creates a table old 052 already created.                              | A disposable run of the real migrator reproduces startup failure at 053. Main 044's repair is also skipped. Fresh-database success is insufficient.                                                                                             |
+| Removing a project with imported legacy threads          | `ws.ts:1238` deletes v2 threads then `ProjectService.ts:350` dispatches a legacy project deletion without force. Legacy command bootstrap still reads `projection_threads`, which the importer preserves. | Source-confirmed partial deletion: legacy validation rejects after v2 thread deletions have committed. No integrated deletion was performed.                                                                                                    |
+| Project deletion from HTTP/CLI bypasses v2 lifecycle     | `project/http.ts:76` and offline `cli/project.ts:457` call project deletion directly, drop `force`, and never enumerate/delete v2 threads. Live CLI uses this HTTP endpoint.                              | Source-confirmed orphaning for v2-only projects and ineffective force for imported projects. HTTP also drops `createWorkspaceRootIfMissing`.                                                                                                    |
+| Checkpoint baseline after an ordinary second run         | `CheckpointDiffQuery.ts:154` requires a scope owned by ordinal 1. `IdAllocator.ts:295` allocates one root scope per thread; the projector upserts its owner to each new run.                              | Sol's real allocator/reducer probe confirms two runs produce one scope owned by run 2. The diff lookup therefore fails even with a valid baseline. Root review broadened the initial cancelled-first-run finding to ordinary multi-run threads. |
+| Diff query reads full transcript                         | Main #8988/#8992 uses narrow checkpoint context; v2 `CheckpointDiffQuery.ts:102` calls full `getThreadProjection`.                                                                                        | Source confirms an unbounded read/decode of unrelated messages/tool bodies and ancestor histories; no latency or memory benchmark was run.                                                                                                      |
+
+The persistence report also confirms that a stale failure can defeat a later snooze, and that startup recovery reads full projections of every active and archived thread. Root rejected the proposed "both settlement settings disabled" early return: a closed PR still intentionally settles under both main and v2, even with those two settings off. Skipping the lookup would change that behavior.

Most backend fixes are exact patches; changed/dropped client patches are assigned explicit client review.                                                                                                                                     |
+| Upgrade protocol / remote compatibility       | Protocol-2 descriptor and socket gating remain. `httpCors.ts` still permits the orchestration protocol header. Current WS and client compatibility tests pass.

+| Local-only worktree bases                     | Main #8751's remote-branch existence check is ported into `ThreadLaunchService.ts:242-286`; V2 falls back to the local base when the requested origin branch is absent.                                                                                                                                                                                 |
+| Service launcher packaging                    | `apps/server/package.json` retains main's dual bundle command including `src/service-launcher.ts`.                                                                                                                                                                                                                                                      |

No desktop runtime test was performed.                                                                                                                                                                                                   |
+| Attachment cleanup transaction ordering       | Main #7941 defers cleanup until after commit. V2 encodes deletion cleanup in its outbox: `Orchestrator.ts:1971`, `EventSink.ts:397` transaction commits event/projection/effect together, then notifies workers at `:447`; cleanup runs through `EffectWorker.ts:285` and `ResourceCleanupService.ts:48`. No v2 pre-commit deletion found on this path. |
+| Pending uploads                               | Copy-claim behavior retains retry source and releases failed claims; focused AttachmentClaims and attachment-store tests pass.                                                                                                                                                                                                                          |
+| Main PR-title prompt fix                      | #9191 TextGenerationPrompts source/tests are identical to main and invoked by the retained text-generation layer; focused tests pass.                                                                                                                                                                                                                   |
+| Billing / usage collection                    | Pricing and transcript/cache readers for #8806, #9024, #8540 are identical to main. In-run provider usage is reviewed separately by the provider/persistence children.                                                                                                                                                                                  |
+| Auth scopes                                   | Every renamed v2 RPC and new project/assets/scheduler RPC remains explicitly classified; no removed main scope boundary found.                                                                                                                                                                                                                          |
+| Legacy transcript and portable handoff limits | Current user/internal docs still describe lost legacy rich history/fresh sessions and the 32,000-character migration budget versus 240-character per-item portable summaries. These are retained architectural tradeoffs from the earlier audit.                                                                                                        |
+
+**Final cross-boundary checks.** Root traced a second path around the HTTP history budget and asked the provider reviewer to validate it through both current clients. F16 is confirmed: an unavailable cold HTTP loader, or a warm reconnect above the replay limits, reaches `ws.ts:860`'s full snapshot and resets progressive-history metadata. Healthy cold opens remain bounded. Root also reviewed the mobile assistant-renderer gap with the client reviewer: bypassing `AssistantMarkdownContent` loses both Codex directive actions and iOS environment-aware inline media (F17). These are concrete caller gaps despite the retained helper implementations.
+
+**Root validation.** `root-server-tests.log`: 6 files, 38 tests passed. `root-compatibility-tests.log`: 1 file, 3 passed. `root-title-cli-tests.log`: 3 files, 35 passed. `root-usage-tests.log`: 3 files, 29 passed. `root-awareness-tests.log`: 1 file, 4 passed. `root-core-tests.log`: 3 files, 12 passed (delegated completion, context handoff, and schedule calculation). Total: 17 file executions, 121 tests passed. The existing tests do not cover populated-project CLI removal or upgraded v2 migration IDs; the separate Sol upgrade probe supplies the migration evidence. No product code changes, repo-wide checks, browsers, live providers, or dev servers.

+# Orchestration V2 persistence, runtime, and performance audit
+
+Date: 2026-09-02  
+Frozen branch: `d2f1f511f4cc833bc930d6c355cd0f9b61e835a0`  
+Current main: `57a66608b918d673eeec7e6c94ea5906b756fcd0`  
+Prior reviewed tip: `c1791ab2637` (`47f5b100440591d2f49aa30cf3bb69eacae07f52` before rebase)
+
+This was a read-only review of `apps/server/src/orchestration-v2` excluding provider adapters, plus the persistence and project boundaries explicitly requested by the root review. No product source or tests were edited. The only writes are this audit report and the retained audit-only probe artifacts beside it. No live database, provider, server, browser, or production state was used.
+
+## Summary
+
+I confirmed seven findings:
+
+| Severity | Classification                          | Finding                                                                                                                                                                       | Evidence basis                                                           |
+| -------- | --------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------ |
+| Blocker  | Branch-upgrade rebase regression        | Existing V2 databases through old migration 052 fail on current 053, while new main migration 044 is skipped.                                                                 | Retained actual migration-runner/in-memory SQLite reproduction.          |
+| High     | Preexisting V2 integration bug          | WebSocket forced project deletion commits V2 thread deletions before legacy project deletion rejects the still-present imported V1 threads.                                   | Deterministic source trace only; no integrated transport run.            |
+| High     | Preexisting V2 integration bug          | HTTP and offline CLI project mutation bypass V2 deletion and drop `force`; create also drops `createWorkspaceRootIfMissing`.                                                  | Deterministic source trace only; no integrated transport run.            |
+| High     | V2 correctness gap                      | Full-thread diff fails after an ordinary second run because production reuses one root scope and updates its `runId`, while the query requires that scope to belong to run 1. | Retained real allocator/projection reproduction plus query source trace. |
+| Medium   | New auto-settlement regression          | A failure that predates a snooze is treated as waking the snoozed thread and can settle it early.                                                                             | Source and policy-test trace; no timed service run.                      |
+| Medium   | Preexisting missed-main performance gap | Checkpoint diff loads an unbounded full V2 thread projection instead of narrow checkpoint context.                                                                            | SQL/source cardinality trace; not benchmarked.                           |
+| Medium   | Preexisting V2 performance gap          | Startup recovery loads every persisted row for every active and archived thread before accepting commands.                                                                    | SQL/source cardinality trace; not benchmarked.                           |
+
+The previously fixed token-usage, legacy metadata, migrated search, missing-worktree recovery, unsettled ordering, SQL visibility, stop-request dependency, nested-fork cursor, true-end pagination, and bounded payload invariants remain present at the frozen head. Focused tests passed, but they do not cover the broken upgrade history or populated-project deletion boundaries.
+
+## Confirmed findings relative to main and prior invariants
+
+### 1. Blocker: an existing pre-rebase V2 database cannot migrate to the current head
+
+**Current code.** The current manifest inserts main's `ClearAutomaticProjectModelDefaults` at ID 44 and shifts the old branch migrations to IDs 45 through 53 (`apps/server/src/persistence/Migrations.ts:58-67`, `:123-132`). The migration API documents that only IDs above the latest recorded ID run (`Migrations.ts:156-169`). The underlying Effect migrator implements exactly that rule and does not compare historical names: `currentId <= latestMigrationId` is skipped at `.repos/effect-smol/packages/effect/src/unstable/sql/Migrator.ts:228-259`, specifically `:248-252`.
+
+Current 053 then unconditionally creates `orchestration_v2_legacy_imports` and its index (`apps/server/src/persistence/Migrations/053_LegacyV1ImportState.ts:9-26`). Neither statement uses `IF NOT EXISTS`.
+
+**Historical evidence.** At `c1791ab2637`, the branch manifest assigned `OrchestrationV2` through `LegacyV1ImportState` IDs 44 through 52 (`apps/server/src/persistence/Migrations.ts` at that commit, lines 58-66 and 122-130). Old `052_LegacyV1ImportState.ts` and current `053_LegacyV1ImportState.ts` are byte-identical; both hash to `efc494840b8319531495a28a82f6624947e54be9846ee6f5a260cd7eae27fe1c`. Main's new 044 performs data repair in both `projection_projects` and `orchestration_events` (`apps/server/src/persistence/Migrations/044_ClearAutomaticProjectModelDefaults.ts:7-50`).
+
+**Actual disposable reproduction.** I ran the real current `runMigrations` with the repository's NodeSqlite layer against an in-memory database. The fixture first applied the current schema bodies corresponding to the old branch sequence and recorded the old IDs and names 44 through 52, ending with `[52, "LegacyV1ImportState"]` and an existing `orchestration_v2_legacy_imports` table. On the next current migration run:
+
+```text
+latest before current run: 52_LegacyV1ImportState
+current run: MigrationError: Migration "53_LegacyV1ImportState" failed
+SQLite cause: table orchestration_v2_legacy_imports already exists
+latest after rollback: 52_LegacyV1ImportState
+```
+
+This exercises the actual migration loader, tracking table, transaction, and SQLite DDL. It does not write any live database.
+
+**Reachable trigger.** Start this frozen build against any database that successfully ran branch tip `c1791ab2637` through migration 52.
+
+**Impact.** Startup fails on 053. Before that failure, the migrator silently treats current 044 through 052 as already applied because their numeric IDs are not above 52. In particular, main's automatic project-model repair at current 044 is never applied to an upgraded branch database. Making only the table creation idempotent fixes the crash but still leaves that repair skipped.
+
+**Compatibility fix.** The migration strategy must explicitly cover every supported historical manifest, not only the reproduced old-052 tip. Making current 053 use `IF NOT EXISTS` would unblock that one cohort, but it would neither apply skipped main 044 nor make arbitrary partially migrated old V2 cohorts safe. For example, an old database ending at 44 can run current 45's shifted copy of the same V2 DDL and collide earlier in the sequence.
+
+Use a manifest-aware compatibility bridge before the ordinary numeric runner, or make every shifted 45-53 step safe for its corresponding old predecessor, then append an idempotent migration that reapplies main 044's repair. A manifest-aware bridge can identify old history by recorded `(migration_id, name)` pairs, reconcile those records/schema to the new numbering, and leave released-main histories distinct. Do not infer history from the maximum ID alone. Add table-driven migration tests for each supported old branch stopping point plus released-main and fresh histories. The exact old-052 regression must remain a fixture. The existing fresh-database test at `apps/server/src/persistence/Migrations/045_046_OrchestrationV2.test.ts:174-230` starts before these IDs and cannot detect any of these upgrade failures.
+
+### 2. High: forced WebSocket project removal can delete V2 threads and then reject the project delete
+
+**Current code.** The WebSocket mutation handler obtains active and archived V2 shells, enforces `force`, and dispatches one `thread.delete` command at a time (`apps/server/src/ws.ts:1238-1258`). Those are independently committed mutations. It then calls `ProjectService.delete` without `force` (`ws.ts:1259-1262`). `ProjectDeleteInput` has no `force` member (`apps/server/src/project/ProjectService.ts:42-45`), and the service dispatches a legacy `project.delete` without it (`ProjectService.ts:348-371`).
+
+The legacy decider rejects a nonempty project unless its command contains `force: true`; when force is present, it deletes legacy threads and the project as one decided sequence (`apps/server/src/orchestration/decider.ts:274-306`). The legacy engine bootstraps that invariant from `getCommandReadModel` (`apps/server/src/orchestration/Layers/OrchestrationEngine.ts:344-345`). That query reads every `projection_threads` row (`apps/server/src/orchestration/Layers/ProjectionSnapshotQuery.ts:430-463`, `:1858-1918`) and constructs the thread read model at `:2010-2049`.
+
+The V1 importer copies rows from `projection_threads`; it does not delete or supersede those rows (`apps/server/src/orchestration-v2/LegacyV1ThreadImporter.ts:459-560`). It also refuses to import the same thread again once a V2 `thread.created` event exists (`LegacyV1ThreadImporter.ts:481-489`).
+
+**Reachable trigger.** Use the WebSocket `project.delete` mutation with `force: true` on a project whose legacy threads have been imported into V2. This is the normal state after the V2 legacy-shell startup import.
+
+**Observed behavior from the source path.** Each V2 thread deletion succeeds first. The subsequent legacy `ProjectService.delete` sees the intact active `projection_threads` rows and rejects because the forwarded command has no force. The project remains, its V1 rows remain, and its V2 thread copies are deleted. A later importer pass will not restore them because their V2 creation events still exist.
+
+**Impact.** A user-authorized project removal fails after partially committing destructive work. The V2 UI loses the project's threads while reporting that the project could not be deleted.
+
+**Minimal fix.** Preserve `force` through `ProjectDeleteInput` and the legacy dispatch so this exact mixed-store path cannot reject after the V2 deletes. Prefer a single project-deletion coordinator used by all transports, with validation over both V1 and V2 and one transactional event commit; otherwise an unrelated failure in the per-thread loop can still partially delete a project. Add a focused test with one imported active thread and one imported archived thread, then force-delete through the WebSocket handler and assert the project and both representations are deleted.
+
+**Classification.** This predates `c1791ab2637`: the current deletion sequence traces to `b1c074b2ec3`, which is an ancestor of the prior rebased tip. It is a previously missed V2 integration bug relative to the V1 force-delete invariant, not a regression introduced by the final rebase.
+
+### 3. High: HTTP and offline CLI project mutations bypass the V2 lifecycle and drop contract fields
+
+**Current code.** `ProjectMutation` explicitly carries `createWorkspaceRootIfMissing` and deletion `force` (`packages/contracts/src/project.ts:70-95`). The WebSocket create handler forwards the former (`apps/server/src/ws.ts:1215-1223`), and `ProjectService.create` uses it when normalizing the workspace (`apps/server/src/project/ProjectService.ts:253-269`).
+
+The production HTTP endpoint is registered at `apps/server/src/server.ts:465-475` from the contract at `packages/contracts/src/environmentHttp.ts:560-575`. Its handler calls `ProjectService` directly. Create omits `createWorkspaceRootIfMissing`, and delete omits `force` and all V2 thread enumeration/deletion (`apps/server/src/project/http.ts:45-80`).
+
+The live CLI uses that HTTP endpoint (`apps/server/src/cli/project.ts:324-338`). Its offline path also maps delete directly to `ProjectService.delete` without force (`cli/project.ts:423-459`). The user-facing command accepts `--force`, describes it as deleting all threads, and includes the flag in its transport command (`cli/project.ts:522-555`). Main V1's invariant and forced sequence are the decider behavior at `apps/server/src/orchestration/decider.ts:274-306`; the prior CLI path passed the force field through to the engine.
+
+**Reachable triggers and actual behavior.**
+
+1. A V2-only project with active or archived V2 threads can be deleted by `POST /api/projects/mutate`. The legacy read model sees no V1 thread, so the project deletion succeeds while the V2 threads remain live and reference a deleted project.
+2. An imported project with legacy rows rejects HTTP or CLI `--force` removal because `force` is dropped.
+3. `t3 project remove`, live and offline, inherits these deletion outcomes despite promising complete forced cleanup.
+4. HTTP and offline CLI project creation with `createWorkspaceRootIfMissing: true` behaves as false because the flag is dropped.
+
+**Impact.** The same typed mutation has materially different safety and filesystem semantics by transport. The deletion variant can orphan V2 threads or make `--force` ineffective.
+
+**Minimal fix.** Route WebSocket, HTTP, live CLI, and offline CLI mutations through one V2-aware project mutation coordinator. Forward both optional fields unchanged. Add transport-parity tests for V2-only populated projects, imported projects, archived threads, force false/true, and missing workspace creation.
+
+**Classification.** The direct HTTP/offline mappings trace to `b56d0e7d53fb`, an ancestor of `c1791ab2637`. This is a previously missed V2 transport integration bug, not a final-rebase regression. New main CLI behavior makes the existing mismatch directly user-facing in `t3 project remove`.
+
+### 4. Medium: auto-settlement treats a failure predating the snooze as an early wake
+
+**Current code.** A future snooze is bypassed whenever `thread.status === "failed"`, with no comparison to `snoozedAt` (`apps/server/src/orchestration-v2/ThreadSettlementService.ts:95-116`, especially `:107-116`). The service then performs normal inactivity/PR evaluation and can dispatch `thread.auto-settle` (`ThreadSettlementService.ts:216-270`). The current test asserts that changing only the status to failed wakes the snooze (`apps/server/src/orchestration-v2/ThreadSettlementService.test.ts:70-87`).
+
+**Main/prior invariant.** Main V1 only treats an error as a wake when the error session was updated after the snooze. It compares `thread.session.updatedAt` with `thread.snoozedAt` (`apps/server/src/orchestration/ThreadSettlementPolicy.ts` at main, lines 89-107, specifically 98-101). Completion has the same after-snooze rule.
+
+**Reachable trigger.** Let a thread fail, then snooze that already-failed thread into the future. On the next minute sweep, V2 classifies the stale failure as an early wake. If the inactivity or PR rule matches, it settles the thread before the requested wake time.
+
+**Impact.** A newer explicit snooze loses to older failure state, so settled/active sidebar placement contradicts the user's latest action.
+
+**Minimal fix.** Require the failure evidence to be newer than `snoozedAt`, as V1 does. The V2 shell already exposes `latestRunCompletedAt`; for a failed latest run, require that timestamp to be non-null and greater than `snoozedAt`. Add tests for failure before snooze (parked) and failure after snooze (candidate).
+
+## Confirmed V2 correctness and performance gaps
+
+### 5. High: full-thread diff fails after an ordinary second run
+
+**Current code.** For `fromTurnCount === 0`, `CheckpointDiffQuery` finds `runs.ordinal === 1`, requires a `root_run` scope whose current `runId` is that first run, and synthesizes its ordinal-0 ref (`apps/server/src/checkpointing/CheckpointDiffQuery.ts:157-180`). `getFullThreadDiff` always delegates to that path (`CheckpointDiffQuery.ts:204-248`).
+
+Production does not keep one distinct root scope row per run. `IdAllocator` derives a checkpoint scope solely from `threadId` and the constant scope name (`apps/server/src/orchestration-v2/IdAllocator.ts:295-300`). `makeRootRunScope` always requests the name `"root"`, but places the current run, node, provider thread, cwd, and creation time in the payload (`apps/server/src/orchestration-v2/CheckpointService.ts:184-210`, with the constant at `:27`). Each ordinary immediate run emits `checkpoint-scope.created` (`apps/server/src/orchestration-v2/Orchestrator.ts:3558-3567`).
+
+Both projection implementations replace the prior scope because the deterministic ID is the same. The in-memory path uses `upsertById` (`apps/server/src/orchestration-v2/ProjectionStore.ts:343-347`), and SQL uses `ON CONFLICT(scope_id) DO UPDATE`, including overwriting `run_id` (`ProjectionStore.ts:1773-1815`, specifically `:1803-1814`). Checkpoint IDs and refs remain stable by shared scope plus ordinal (`apps/server/src/orchestration-v2/CheckpointService.ts:161-181`). Thus, after run 2, the one root scope row belongs to run 2 while the valid ordinal-0 baseline from run 1 remains under that shared scope ID.
+
+**Test-fixture mismatch.** `CheckpointDiffQuery.test.ts:23-49` fabricates `firstScopeId` and `secondScopeId` and keeps both rows. That state cannot be produced by the real allocator for two root runs in one thread. The happy-path assertion at `:70-96` therefore hides the production failure. The missing-baseline test at `:176-196` also treats absence of a run-1-owned scope as an error, even though that is the normal projection after run 2.
+
+**Actual disposable allocation/projection probe.** I ran the real `IdAllocatorV2.allocate.checkpointScope` twice for the same thread and `"root"`, then applied two real `checkpoint-scope.created` events through `applyToProjection`. The two allocated IDs were equal; after the second event, `checkpointScopes.length` was 1 and the stored row's `runId` was `run:2`. The one-case audit-only Vitest probe passed and was removed afterward.
+
+**Reachable trigger and behavior.** Complete two ordinary immediate runs in a Git workspace, then request `getFullThreadDiff` to turn 2. The target checkpoint and shared ordinal-0 ref exist. The sole root scope now has `runId` 2, so the lookup constrained to run 1 returns undefined and the query raises `CheckpointRefUnavailableError` for the `from` ref. A cancelled/deferred first run is another trigger, but is not required.
+
+**Impact.** Full-thread diff is unavailable for normal multi-turn threads from the second completed run onward.
+
+**Minimal fix.** Stop joining the zero baseline through `firstRun.id`. Resolve the root scope by the target checkpoint's shared `scopeId`, then use that scope's ordinal-0 checkpoint/ref. Prefer the stored ready baseline ref and validate that it exists. Rewrite the happy-path test with the real allocator or one shared root scope whose current `runId` is run 2, and retain separate corrupt/missing-baseline coverage.
+
+**Classification.** The bad lookup traces to `b56d0e7d53fb`, while deterministic scope reuse and projection upsert predate it. `b56d0e7d53fb` is an ancestor of `c1791ab2637`, so this is a previously missed V2 correctness bug rather than a final-rebase regression.
+
+### 6. Medium: checkpoint diff reintroduces unbounded transcript hydration fixed on main
+
+**Current code.** Every nonempty diff first calls `ThreadManagementService.getThreadProjection` (`apps/server/src/checkpointing/CheckpointDiffQuery.ts:102-121`). V2's method is the unwindowed `readProjection` path (`apps/server/src/orchestration-v2/ProjectionStore.ts:2598-2599`). With no window, that path loads every turn item (`ProjectionStore.ts:2023-2030`) and selects all rows from each run, attempt, node, session, provider thread/turn, request, message, plan, checkpoint, and handoff table (`ProjectionStore.ts:2163-2399`), then decodes all of them (`ProjectionStore.ts:2401-2433`). Fork ancestry can recurse through additional full projections (`ProjectionStore.ts:2467-2589`).
+
+**Main invariant.** Main #8988 (`b17cc3d1bf0`) reduced full tool-output hydration, and #8992 (`7e460f429b7`) added a dedicated full-thread-diff query. The retained V1 implementation demonstrates the intended shape: a small thread/workspace query at `apps/server/src/orchestration/Layers/ProjectionSnapshotQuery.ts:985-1001`, a single-row full-diff query at `:1533-1562`, and narrow service methods at `:2512-2583`. Main's `CheckpointDiffQuery` calls `getThreadCheckpointContext` or `getFullThreadDiffContext`; current V2 does neither.
+
+**Reachable trigger.** Request a turn diff or full-thread diff for any long thread, especially one with large tool outputs or fork ancestry.
+
+**Impact/cardinality.** Work is O(all persisted child rows for the thread and its fork ancestors), although the operation needs only workspace identity, run status/ordinal, scope identity, and a few checkpoint refs. A diff request can load and decode unrelated transcript bodies into memory.
+
+**Minimal fix.** Add V2 SQL queries equivalent to `getThreadCheckpointContext` and `getFullThreadDiffContext`, against V2 projection tables, and have the diff service use them. The full-thread endpoint needs one target checkpoint, the latest available completed turn count, a valid zero baseline, and the workspace path; it should not instantiate `OrchestrationV2ThreadProjection`. Add a cardinality test with a large unrelated tool payload and assert that the narrow query does not read/decode it.
+
+**Classification.** This gap was already present at `c1791ab2637`, even though main's #8988/#8992 optimizations were already in its ancestry. It is a missed main performance invariant from the prior review, not a new final-rebase regression.
+
+### 7. Medium: startup recovery fully hydrates every active and archived thread before readiness
+
+**Current code.** Recovery loads the V2 shell, iterates `shell.threads` plus `shell.archivedThreads` sequentially, and calls full `getThreadProjection` for every one (`apps/server/src/orchestration-v2/ProviderRuntimeRecoveryService.ts:470-499`). The reconciliation only needs nonterminal runs, pending runtime requests, live provider/background state, and unsettled process-bound effects (`ProviderRuntimeRecoveryService.ts:130-175` and the remainder of `reconcileProjection`).
+
+As above, `getThreadProjection` is unbounded (`apps/server/src/orchestration-v2/ProjectionStore.ts:2023-2030`, `:2163-2433`, `:2598-2599`) and recursively loads complete source projections for forked threads (`:2467-2589`). Startup awaits this recovery as an ordered phase (`apps/server/src/serverRuntimeStartup.ts:456-508`) and does not signal command readiness until `:615-617`.
+
+**Reachable trigger.** Restart an environment with many terminal threads, archived threads, long transcripts, tool payloads, checkpoints, or fork chains. No active provider work is required.
+
+**Impact/cardinality.** Startup database reads and decoding are O(total retained V2 projection history), not O(recoverable runtime state). The loop is sequential across threads. This can delay every local and remote client from issuing commands and creates a peak-memory cost before readiness. I did not benchmark it, so no latency number is claimed.
+
+**Classification.** This is a preexisting V2 design/performance gap, not a regression newly introduced by the final rebase. V1's startup read model also scans all thread shells, but it does not hydrate every transcript row, so this is not classified as a main-both bug.
+
+**Minimal fix.** Add an indexed recovery-candidate query that returns only thread IDs with a nonterminal run, pending request, live provider session/background item, or pending/running process-bound outbox entry. Then load a narrow recovery projection for only those IDs. Add a startup test containing many large terminal archived threads and assert that they are not passed to full projection reads.
+
+## Rejected candidate
+
+### Source-control lookup with inactivity and merge settings disabled is intentional
+
+An earlier draft classified recurring Git/PR lookup as unnecessary when `sidebarAutoSettleAfterDays` is null and `sidebarAutoSettleOnMerge` is false. Reviewer feedback correctly rejected that conclusion.
+
+Closed pull requests are an always-on settlement rule. V2 accepts `state === "closed"` regardless of `autoSettleOnMerge` and only gates the `"merged"` state on that setting (`apps/server/src/orchestration-v2/ThreadSettlementService.ts:71-91`). `shouldAutoSettleThread` evaluates that PR rule before the optional inactivity rule (`:119-140`). Main V1 has the same policy (`apps/server/src/orchestration/ThreadSettlementPolicy.ts:45-86`), and its test explicitly expects a closed request to settle with merge settlement disabled (`ThreadSettlementPolicy.test.ts:65-66`).
+
+The retained audit probe confirms that a closed PR newer than the user's last action settles with both optional settings off. Therefore the sweep must inspect PR state to preserve current product behavior. An early return based only on those settings would be a regression. No performance finding or fix recommendation remains for this candidate.

+The retained `audits/orchestrator-v2/2026-09-02/persistence-runtime-probes.test.ts` uses the actual migration runner with in-memory SQLite, the real checkpoint allocator and projection reducer, and the production V2 settlement policy. Its fixtures use typed domain events, branded identifiers, real `DateTime.Utc` values, `emptyProjection`, and `threadShellFromProjection`; there are no permissive projection/event casts. Its migration case expects and captures the current 053 failure, so the probe suite itself passes while reproducing the blocker. Its scope case confirms that two root-run allocations produce one shared scope row whose `runId` is overwritten by run 2. Its policy case records the reviewer rejection above. Audit probes are not included in the 90-product-test total.
+
+Exact rerun command and output are retained in `audits/orchestrator-v2/2026-09-02/persistence-runtime-probes.log`.
+
+## Remaining validation gaps
+
+- I did not mutate product tests to add the missing historical-manifest fixtures. The retained audit-only probe uses the same migration loader and SQL layer for the confirmed old-052 cohort; other supported partial old-branch stopping points still need table-driven validation.
+- I did not invoke a live WebSocket/HTTP server or CLI. The project-deletion outcomes are deterministic source traces across typed handlers, committed V2 commands, and the legacy decider. An integrated disposable server test should be added with the fixes.
+- I did not benchmark startup recovery or checkpoint diff. Cardinality claims above follow the explicit unwindowed SQL and loops; they do not claim measured latency or memory.
+- I did not test live GitHub/PR providers. Settlement PR grouping and local Git call order were inspected statically.
+- Provider adapters, browser clients, desktop/mobile behavior, build/auth compatibility, and title retries are assigned to other reviewers/root.
+- The explicit server-update continuation gap needs a product decision and V2 design; it is not silently counted as passing parity.

+# Orchestrator V2 provider behavior audit
+
+Date: 2026-09-02  
+Audited HEAD: `d2f1f511f4cc833bc930d6c355cd0f9b61e835a0`  
+Comparison main: `57a66608b918d673eeec7e6c94ea5906b756fcd0`  
+Prior reviewed object: `47f5b100440591d2f49aa30cf3bb69eacae07f52`  
+Rebased prior-equivalent tip: `c1791ab2637`
+
+## Verdict
+
+The supplied main is an ancestor of the frozen HEAD, and the branch is 332 commits ahead. The previously reported provider fixes survive the rebase. I found five confirmed behavior regressions against current main V1:
+
+1. Cursor background text generation runs a full agent with its sandbox and approval boundary disabled.
+2. Claude workspace image reads do not become image previews in either current V2 client projection.
+3. OpenCode Stop reports descendant cleanup as successful even when child discovery or abort fails or times out.
+4. Releasing an OpenCode V2 session connected to an external server never asks that server to abort root or child work.
+5. V2 reconnect and HTTP-failure fallbacks bypass the bounded thread-snapshot path and can send the full lifetime projection over WebSocket.
+
+The Cursor SDK migration itself is intentional, but I found no evidence that removing the metadata-generation write guard was an accepted part of it. The Claude result is a missing user-visible main feature. The OpenCode findings partially port main's `#9005` fix but leave reachable stop/teardown behavior weaker than V1. The snapshot issue is not the ordinary healthy cold-open path—the bounded HTTP request protects that case—but it is an active fallback used by both current clients.
+
+## Confirmed regressions
+
+### P1 — Cursor metadata generation runs with unrestricted write/tool access
+
+**Current V2 evidence:** `apps/server/src/textGeneration/CursorTextGeneration.ts:75-157`.

+- Every Cursor commit message, change-request description, branch name, and thread title calls `Agent.prompt` with `mode: "agent"`, `local.autoReview: false`, and `local.sandboxOptions.enabled: false` (`90-104`; callers at `159-251`). The focused test explicitly pins those options but mocks the SDK, so it does not exercise their permission behavior (`CursorTextGeneration.test.ts:38-85`).
+- The installed dependency is `@cursor/sdk@1.0.22`. Its public types expose only `"agent" | "plan"` modes and a boolean sandbox switch (`node_modules/.pnpm/@cursor+sdk@1.0.22/node_modules/@cursor/sdk/dist/esm/options.d.ts:3-4, 63-65, 108-145, 218-240`). Inspection of the installed runtime bundle shows that `enabled: false` immediately selects `defaultSandboxPolicy: { type: "insecure_none" }`, before considering the loaded per-user sandbox policy; because that policy is insecure and `autoReview` is false, it supplies neither `approvalMode` nor a `pendingDecisionProvider` (`dist/esm/357.js:1`). The same bundle maps `mode: "agent"` to the native `AGENT` mode and implements `Agent.prompt` as create/send/wait/dispose, so this is the normal tool-capable local agent path rather than a text-only inference call.
+
+**Main evidence:** supplied main's `apps/server/src/textGeneration/CursorTextGeneration.ts:85-105` starts Cursor ACP and deliberately calls `runtime.setMode("ask")` before prompting. The accompanying Cursor ACP capability names Ask as “Request permission before making any changes,” contrasted with Code's full tool access (`apps/server/scripts/acp-mock-agent.ts` at supplied main: `271-287`). The SDK migration commit `6c78a01831d` documents the intentional boundary/auth/model-discovery change, but neither its message nor its implementation records an intentional relaxation for background metadata generation.
+
+**Reachable trigger:** Select Cursor as the text-generation/source-control writer. Initial and regenerated titles invoke the service against the real worktree (`ThreadTitleRegenerationService.ts:184-245`), commit generation passes the real source-control cwd (`GitManager.ts:1618-1657`), and automatic worktree naming does likewise (`ThreadLaunchService.ts:178-213`). The title prompt explicitly tells the model to use available tools for linked-only context (`TextGenerationPrompts.ts:219-243`). Any resulting shell, edit, or delete tool call executes without main's ask boundary; the user message and diff content supplied to these prompts can also request or induce such a call.
+
+**User impact:** A background title/branch generation or a commit/PR-copy request can modify or delete workspace files, run commands, or perform other agent actions even though the operation is presented as metadata generation. Explicitly disabling the SDK sandbox also overrides a user's configured Cursor sandbox for these calls.
+
+**Minimal recommendation:** Restore an enforced non-writing boundary for Cursor text generation before using `Agent.prompt`. The installed SDK does not expose an Ask mode, and `sandboxOptions.enabled: true` maps to workspace read-write, so neither that flag nor an unverified switch to Plan should be treated as equivalent. Use a documented SDK text-only/read-only policy if one is added; otherwise retain a guarded metadata path or do not offer Cursor for these background generators. Add a behavioral integration test with a fake/local SDK runtime that attempts shell and file-write tools and proves they are denied; do not merely assert option shape.
+
+### P1 — OpenCode Stop swallows descendant cleanup failures
+
+**Current V2 evidence:** `apps/server/src/orchestration-v2/Adapters/OpenCodeAdapterV2.ts:2986-3069`.
+
+- V2 first waits for `session.abort` on the root (`3013-3029`). It then describes descendant cleanup as best-effort (`3030-3033`).
+- A failed `session.children` call is converted to `Option.none` (`3038-3043`), each child `session.abort` failure is ignored (`3049-3055`), and the whole traversal's 15-second timeout or failure is ignored (`3058-3059`). The outer `ProviderAdapterInterruptError` mapping therefore never sees any descendant cleanup failure.
+- V2 also waits up to ten seconds for the root HTTP abort even when native session events have already acknowledged or completed cancellation (`3013-3029`).
+
+**Main evidence:** commit `62d39bf00d` (`fix(server): stop OpenCode child sessions (#9005)`). At main, `apps/server/src/provider/Layers/OpenCodeAdapter.ts:707-774` walks all descendants and returns the first non-not-found list/abort failure. Its interrupt state machine at `2987-3122` races the HTTP request with native acknowledgment/completion and propagates a descendant failure or timeout unless the turn has independently completed.
+
+**Reachable trigger:** An OpenCode turn has spawned a task child or grandchild and the user presses Stop while `session.children` or a child `session.abort` errors or hangs. A slow root abort request with a prompt native acknowledgment also reaches the avoidable delay.
+
+**User impact:** T3 can acknowledge Stop while one or more OpenCode child sessions continue executing commands or modifying files. Failures leave no caller-visible indication. The root abort can also keep the Stop command pending for up to ten seconds after native cancellation is already known.
+
+**Minimal recommendation:** Port main's cancellation state machine into V2: keep prompt-admission cancellation, race root abort against native acknowledgment/terminal completion, traverse descendants with the cycle guard and bounded concurrency, ignore only explicit not-found responses, and propagate the first other failure or timeout while the cancellation is still live. Add adapter tests for nested children, list failure, child-abort failure, timeout, and acknowledgment winning a pending HTTP request.
+
+### P1 — External OpenCode work survives V2 session release
+
+**Current V2 evidence:**
+
+- An OpenCode session may connect to an external configured server at `apps/server/src/orchestration-v2/Adapters/OpenCodeAdapterV2.ts:882-902`.
+- Its only explicit scope finalizer aborts the local SSE subscription controller at `apps/server/src/orchestration-v2/Adapters/OpenCodeAdapterV2.ts:2488-2496`. The only root/descendant `session.abort` calls in this adapter are inside `interruptTurn` at `3013-3059`; session release has no corresponding path.
+- The V2 runtime interface has no close/teardown callback (`apps/server/src/orchestration-v2/ProviderAdapter.ts:470-535`). The manager releases sessions by closing the adapter scope (`apps/server/src/orchestration-v2/ProviderSessionManager.ts:611-706`) for idle timeout, runtime error, manual shutdown, and server shutdown (`ProviderSessionManager.ts:47-52, 761-839, 1361-1389, 1555-1565`).
+- Normal server shutdown calls `providerSessions.shutdown` before terminalizing durable work (`apps/server/src/serverRuntimeStartup.ts:386-402`). For an external OpenCode server, closing T3's scope only disconnects its event stream; there is no owned local child process whose teardown could stop the remote sessions.
+
+**Main evidence:** the same main commit, `62d39bf00d`. Main implements `abortOpenCodeSessionForTeardown` at `apps/server/src/provider/Layers/OpenCodeAdapter.ts:776-787` and calls it from normal context stop at `828-860`. It explicitly aborts the parent, snapshots the child tree, and aborts descendants before closing local handles.
+
+**Reachable trigger:** Use an OpenCode provider configured with `serverUrl`, start work, then shut down T3, manually close/detach the single-thread session, hit the idle-release path, or lose the V2 event stream without first completing a successful explicit interrupt.
+
+**User impact:** T3 marks/releases the session and loses its event stream while the external OpenCode server can continue root or child work unseen. On shutdown this can leave commands and file writes running after the local UI/server has stopped.
+
+**Minimal recommendation:** Add a provider-runtime teardown effect (or an OpenCode-specific scope finalizer) that best-effort aborts the root and the complete descendant tree before the SSE subscription is closed. Preserve strict failure reporting for explicit Stop, but time-box and log teardown failures. Cover external connections and all four manager release reasons in focused tests.
+
+### P1 — V2 WebSocket snapshot fallbacks bypass the bounded history path
+
+**Current V2 evidence:**
+
+- The server advertises `threadSnapshotPagination`, but the V2 subscription input has no window/limit field (`apps/server/src/ws.ts:770-792`; `packages/contracts/src/orchestrationV2.ts:2430-2443`). Both a subscription without `afterSequence` and a resume rejected by the 128-event or 1 MiB replay limits call `snapshotThenLive` (`apps/server/src/ws.ts:829-922`; limits at `apps/server/src/orchestration-v2/ThreadStream.ts:1-50`). That function calls the unwindowed `getThreadSnapshot`, projects it, and emits it as one socket item (`ws.ts:860-884`).
+- The call remains unwindowed through `ThreadManagementService` (`apps/server/src/orchestration-v2/ThreadManagementService.ts:413-423`). `ProjectionStore` consequently reads every turn item and all rows in each projection collection without a `LIMIT` when `window` is absent, and recursively does the same for inherited source-thread history (`apps/server/src/orchestration-v2/ProjectionStore.ts:2023-2030, 2146-2399, 2467-2589, 2601-2626`). The bounded SQL read is a separate API at `2628-2677`.
+- Wire projection caps individual detail/dynamic values at 32 KiB/16 KiB, but maps every `turnItems` and `visibleTurnItems` entry; it does not cap collection cardinality (`apps/server/src/orchestration-v2/WireProjection.ts:7-99`). The bounded HTTP implementation instead budgets at most 75 timeline items and about 1 MiB, including the duplicate local-item cost across those two arrays (`apps/server/src/orchestration-v2/threadHistoryPaging.ts:9-16, 61-79, 420-496`).
+- The current web and mobile runtimes both install the shared bounded HTTP loader. A healthy cold open therefore gets the intended bounded snapshot first. The loader has a six-second budget and deliberately returns `unavailable` on transient failure so the socket is used (`packages/client-runtime/src/state/boundedThreadSnapshotHttp.ts:23-65, 109-156`). When no projection was installed, the client subscribes without `afterSequence`; a warm cached projection skips HTTP and subscribes with its sequence (`packages/client-runtime/src/state/threads.ts:580-647`; the latter behavior is pinned at `threads-sync.test.ts:289-308, 472-507`). A received socket snapshot is installed as a full replacement and clears progressive-history metadata (`threads.ts:288-307`), so this is neither a dead nor control-plane-only fallback.
+
+**Main evidence:** Main `#8992` (`7e460f429b`) bounds replay and falls back to a snapshot; `#9000` (`a9ffb827961`) adds bounded snapshot activity reads/projection. Crucially, current main's subscription contract accepts `turnLimit` and defines it as the fallback-snapshot window (`packages/contracts/src/orchestration.ts` at supplied main: `630-653`). The client always sends its ten-user-turn initial limit to pagination-capable servers specifically so a missing cursor or failed resume does not redownload the full thread (`packages/client-runtime/src/state/threads.ts` at supplied main: `43-50, 560-637`), and the server passes that limit into `getThreadDetailSnapshot` on the fallback path (`apps/server/src/ws.ts` at supplied main: `1525-1654`). Main `#9032` (`e86604d337`) avoids repeated full-message reads while streaming; it does not close or establish this snapshot bound and is not used as proof for the finding.
+
+**Reachable trigger:** Either (1) open a thread with an empty client cache while the bounded HTTP request times out or fails transiently, or (2) reconnect/foreground a warm cached thread after more than 128 thread events or more than 1 MiB of encoded replay events accumulated. The first subscribes without a cursor; the second makes `decideThreadResume` choose snapshot. Both reach the same unwindowed snapshot call.
+
+**User impact:** On a long-lived thread, the server queries and decodes every historical row across the projection tables (and inherited parent history), serializes the full projection, and sends it as one WebSocket snapshot. Work and payload size therefore grow with lifetime thread cardinality despite the advertised paginated path; remote clients are especially exposed when the bounded HTTP request is the part that failed. The client then loses its load-earlier cursor because it treats the socket result as complete. This audit proves the unbounded cardinality and reachable paths from source; it did not measure a percentage, frame size, or memory peak.
+
+**Minimal recommendation:** Extend the V2 subscription with a pagination-capable fallback request, then build its socket snapshot through `getThreadSnapshotWindow` plus the existing bounded projection/budget logic and carry progressive-history metadata in the stream item. Preserve an explicit full fallback for legacy clients if needed. Add focused cases for a warm bounded cache whose gap exceeds 128 events and a cold loader-unavailable path; assert a bounded timeline, retained live control state, a usable history cursor, and the payload-budget signal rather than a timing percentage.
+
+### P2 — Claude workspace image reads lose image-preview projection
+
+**Current V2 evidence:**
+
+- Claude's V2 tool classifier only permits `command_execution`, `file_change`, `dynamic_tool`, and `web_search`; `Read` is always `dynamic_tool` (`apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts:1392-1447`).
+- The actual tool-start caller has the parsed `toolInput` but calls `classifyClaudeNativeTool(input.toolName)` without it (`ClaudeAdapterV2.ts:3601-3630`). Artifact construction can consequently emit only those four item types (`ClaudeAdapterV2.ts:3001-3039`).
+- V2 does retain the native Read input in the generic `dynamic_tool.input` field (`ClaudeAdapterV2.ts:3001-3039`; contract at `packages/contracts/src/orchestrationV2.ts:1069-1075`), so contract shape alone does not prove the preview is lost. The actual client projections do: web puts the input only in `toolData` and supplies neither `detail` nor `viewedImagePath` (`apps/web/src/session-logic.ts:591-597`), and mobile does the same (`apps/mobile/src/lib/threadActivity.ts:467-472`).
+- The shared preview detector reads only an explicit `viewedImagePath` or a single-line `detail` on a Read entry; it never inspects `dynamic_tool.input` (`packages/client-runtime/src/work-log/presentation.ts:354-385`). Consequently the web renderer receives `null` at `MessagesTimeline.tsx:3275-3282` and cannot enter its image branch at `3378-3389`; mobile likewise receives `null` at `apps/mobile/src/features/threads/thread-work-log.tsx:651-665` and skips its image branch at `759-770`. The expanded inspector renders structured input/output JSON only (`apps/web/src/components/chat/V2ItemInspector.tsx:227-244`).
+
+**Main evidence:** commit `d0b19b32e0` (`fix(claude): preview images read from the workspace (#9119)`). Main's `apps/server/src/provider/Layers/ClaudeAdapter.ts:717-727` recognizes only `Read`/`Read file` calls whose `file_path` or `path` passes `isWorkspaceImagePreviewPath`; `730-777` classifies them as `image_view`; `1188-1192` retains the path as display detail. Main's regression test at `apps/server/src/provider/Layers/ClaudeAdapter.test.ts:1438-1574` verifies the streamed Read input transitions from a generic start to `image_view` updates/completion carrying the image path.
+
+**Reachable trigger:** Claude invokes its `Read` or `Read file` tool for a supported workspace image such as PNG, JPEG, GIF, or WebP.
+
+**User impact:** V2 renders a generic Read tool row (and structured JSON when expanded) instead of main's inline workspace image preview on both web/desktop and mobile.
+
+**Minimal recommendation:** A new turn-item variant is not required. On both client projections, recognize `dynamic_tool` names `Read` / `Read file`, extract `file_path` or `path` from `input`, validate it with the shared workspace-image predicate, and populate `viewedImagePath`; alternatively project the same explicit path server-side if maintainers want a provider-neutral contract field. Preserve the generic-start-to-image transition when streamed partial JSON reveals the path only later. Add the main streamed-input regression case plus web and mobile projection/render coverage.

+
+Provider execution paths inspected: Claude Agent SDK; Codex app-server; Cursor Agent SDK; OpenCode SDK/SSE; Grok through the flavored ACP adapter; ACP Registry through the generic ACP adapter; provider driver creation, model/skill snapshot plumbing, session lifecycle, and the relevant orchestration V2 contracts.
+
+## Intentional differences
+
+- **Restart continuation is deliberately withheld in V2.** Main's `5b7d72aad1` / `#9167` keeps active V1 threads resumable across server restarts. The frozen HEAD's commit message explicitly says the server-side continuation markers were not ported because they live in the V1 session directory and V2 recovery terminalizes running runs. That matches `ProviderRuntimeRecoveryService.ts:130-190, 450-526`. I do not classify this as a regression without a V2 durability design.
+- **Cursor uses the Cursor Agent SDK rather than main V1's ACP boundary.** Its orchestration capabilities intentionally advertise no live approvals/structured questions and no native fork/rollback (`CursorAdapterV2.ts:101-158`). I found no evidence that the chosen SDK boundary exposes equivalent interactive callbacks that V2 is silently dropping. This intentional D01/API-boundary change does not make unrestricted background text generation intentional; that separate loss is the confirmed finding above.
+- **V2 session residency differs from V1.** The V1 persisted-session lookup optimization does not map one-for-one to V2's keyed in-memory manager. This is an architectural difference, not missing parity.
+
+## Suspected or unverified cases
+
+- **Execution-triggered per-cwd skill refresh:** main V1 refreshes the workspace provider snapshot both after starting a provider session and when reusing one (`ProviderCommandReactor.ts` at supplied main: `660-681, 712-740`). V2 has the registry RPC (`apps/server/src/ws.ts:1574-1587`) and web proactively requests a missing cwd snapshot (`apps/web/src/components/chat/ChatComposer.tsx:1143-1194`), but I found no equivalent refresh in V2 launch/run execution. Claude independently scans skills while forming its query, so execution is safe there; Codex/OpenCode slash-command discovery appears UI-facing. I did not find a reachable current-client failure, so this remains a parity/test gap rather than a confirmed regression.
+- **Active-detail WebSocket coalescing/performance:** main commit `7e4ce3bbb1` adds a semantic, stable-tool-call coalescer with a 50 ms/512-event bound before V1 live thread-detail delivery (`ThreadLiveEventCoalescer.ts` at that commit: `13-14, 20-89, 91-205`; V1 `ws.ts:1499-1513`). The V2 thread subscription maps every stored event directly to a wire event at `apps/server/src/ws.ts:807-827` and uses that same uncoalesced stream for live delivery at `883, 918`. The grouped/coalesced V2 streams at `ws.ts:1001-1026, 1181-1190` are shell/archive paths, not active thread detail. Static provider paths can generate repeated full-state events: Cursor sends a node plus turn-item update on every shell-output delta (`CursorAdapterV2.ts:1094-1102, 1838-1847`), ACP/Grok reprojects tool state for every native tool-call update (`AcpAdapterV2.ts:2604-2613, 3693-3701`), and OpenCode reprojects every tool `message.part.updated` (`OpenCodeAdapterV2.ts:2270-2295`). Codex assistant text has its own adapter coalescer, but each `item/plan/delta` emits full node, plan, and turn-item events (`CodexAdapterV2.ts:3171-3205`). This establishes exposure to chatty frames, not a measured regression: V2 event shapes, persistence, client reduction, and provider fixture rates differ from V1, and main's coalescer targeted `tool.updated`, not plan deltas. Add an integrated V2 stream test using a burst of stable tool updates plus an interleaved boundary, and record frame/byte counts on checked-in provider replays before assigning severity or claiming the main PR's 90% figure. Any fix should coalesce only wire delivery, retain persisted events, key by turn plus stable item identity, and preserve sequence/completion-marker semantics.
+
+## Known-main bugs
+
+None identified in the provider behaviors used as comparison evidence. The five findings above are branch omissions or weaker semantics, not defects inherited unchanged from main.
+
+## Verification and gaps
+
+- Read `AGENTS.md` and `.repos/effect-smol/LLMS.md` before assessing Effect scopes, finalizers, races, and error handling.
+- Verified the exact frozen HEAD, supplied main ancestry, and 332-commit count before and after inspection.
+- Ran:
+
+  ```text
+  vp test run \
+    apps/server/src/orchestration-v2/AttachmentPrompt.test.ts \
+    apps/server/src/orchestration-v2/ProviderTurnTokenUsage.test.ts \
+    apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts \
+    apps/server/src/orchestration-v2/Adapters/OpenCodeAdapterV2.test.ts
+  ```
+
+  Result: 4 files passed, 96 tests passed.
+
+- Ran the bounded follow-up suite for the Cursor SDK wrapper and the web/mobile work-log projections:
+
+  ```text
+  vp test run \
+    apps/server/src/textGeneration/CursorTextGeneration.test.ts \
+    packages/client-runtime/src/work-log/presentation.test.ts \
+    apps/web/src/session-logic.test.ts \
+    apps/mobile/src/lib/threadActivity.test.ts
+  ```
+
+  Result: 4 files passed, 81 tests passed. These tests confirm the current option and projection shapes; they do not attempt a live provider call or prove tool denial/image rendering, which is why the missing behavioral cases remain gaps below.
+
+- Per instructions, no live provider, server, browser, external OpenCode server, or production state was used. SDK behavior was validated from checked-in types, testkits, full callers, current-main adapter tests, and the exact installed `@cursor/sdk@1.0.22` type declarations/runtime bundle.
+- The focused suite has no Cursor text-generation tool-denial test, no V2 Claude workspace-image projection test, no OpenCode child-list/child-abort failure test, no external-server session-release test, and no V2 large-gap or HTTP-unavailable test asserting a bounded socket snapshot with progressive-history metadata. Those are the direct verification gaps behind the five recommendations.
+- The final WebSocket snapshot check was source-only; no additional test was run because the existing fixtures stop at client subscription inputs or the pure replay decision and do not exercise the server fallback through client history installation.
+- No focused V2 test currently demonstrates semantic coalescing or establishes a frame/byte budget for active tool-update or plan-delta bursts. No performance percentage was inferred from main's benchmark claim.
+- No product or test source was edited. This report is the only file written by this audit.

+# Orchestrator V2 re-audit, September 4, 2026
+
+The branch still needs corrective work before rollout. **13 of the previous 17 findings remain open; four are fixed. This audit adds five findings: four missed provider ports and one scheduler scaling defect.** Fifteen main-only commits are assessed separately: eight at the initial capture and seven that arrived during review. Their absence is not evidence of another bad rebase, and V1-specific changes need an equivalent-behavior check before being ported.
+
+The most consequential open paths are historical V2 upgrades, mixed V1/V2 project deletion, full checkpoint diffs after a second run, and provider operations that hang or continue after the UI considers them finished. The recent recovery, query, coalescing, and client rendering fixes are real improvements and are credited below.
+
+This was an audit, not an implementation pass. Three GPT-5.6 Sol reviewers worked in bounded parallel groups; the parent reviewed their evidence and resolved classification disagreements. No product source or existing test was edited by this audit. Artifacts and audit-only probes are kept here, uncommitted, as requested. Existing local work was preserved.

+
+Committed findings use the frozen Git revisions, not whatever another process subsequently writes into this worktree. Local changes are reviewed separately in the domain reports. The initial capture contained 56 dirty paths; the final overlay contains 59. Later changes and their hashes are recorded in `worktree-final-manifest.json` and `worktree-drift.diff`; `closing-references.json` confirms they had not changed again. Frozen copies end in `.snapshot` so they cannot accidentally become product test suites. The local `main` branch is stale and was not used as the baseline.
+
+The initial file and main-commit inventories are in [changed-files.tsv](changed-files.tsv), [main-feature-file-map.tsv](main-feature-file-map.tsv), and [main-since-prior.txt](main-since-prior.txt). [changed-files-final.tsv](changed-files-final.tsv) and [main-late-arrivals.txt](main-late-arrivals.txt) record the closing comparison and seven additional commits. The [feature map](FEATURE-MAP.md) records behavior, surfaces, exceptions, and validation limits. Inventory coverage is not a claim that every changed line or every live integration was executed. Main commits after the explicit cutoff are outside this audit.

+
+Range-diff review found 265 equal patches, 64 changed pairs, three unmatched old patches, and four unmatched new patches. The old Codex availability patch was absorbed by the managed-driver initializer, not lost. Integration/lint bookkeeping accounts for two unmatched pairs. The two remaining new commits carry resource work and main reconciliation. See [the concise range-diff inventory](prior-audit-range-diff-summary.txt); an unmatched patch alone was not treated as a regression.

+The detailed reports contain file/line evidence, actual callers, main counterparts, and proof limits:
+
+- [Persistence and lifecycle](persistence.md): F01, F03-F05, F13-F15, F22; historical migration and allocator/policy probes.
+- [Providers](providers.md): F06-F08, F11, F18-F21; all seven built-in drivers and capability differences.
+- [Clients](clients.md): F02, F09-F10, F17, inherited rendering and queue decisions, recent main UI/performance work.
+- [Cross-cutting review](cross-cutting.md): F12, F16, protocol/remote boundaries, packaging, usage, coalescing, rebase inventory, CI.
+
+F04/F05 can share a project lifecycle implementation, but mixed-store deletion and each transport need distinct coverage. F06/F07 share traversal mechanics but have different contracts: explicit Stop surfaces failure; release is bounded and logs failure. F14 is fixed without fixing F03. Live coalescing is fixed without fixing F16 or unused-stream lifetime.

+## Intentional differences and decisions
+
+Previously accepted architectural choices are not reopened merely because their implementations differ from V1.
+
+| ID  | Question                                                       | Current behavior and recommendation                                                                                                                                                                                                                    |
+| --- | -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| D01 | Port continuation after a server update now?                   | V2 explicitly withholds `serverUpdateThreadContinuation`; recovery terminalizes running work. Main resumes it. Port before claiming full update-continuation parity, or keep the deferral explicit.                                                    |
+| D02 | Should inherited message/plan links use their source worktree? | Normal web/mobile Markdown uses the active fork; the inspector uses source ownership. Decide source-history versus current-fork semantics before changing this. Main has no equivalent inherited-row oracle.                                           |
+| D03 | Keep the Cursor SDK boundary?                                  | Keep the accepted SDK migration and explicit unsupported capabilities. F08's metadata permission loss is an independent bug.                                                                                                                           |
+| D04 | Keep the limited legacy import?                                | Keep the documented metadata/message import, fresh provider continuation, and bounded imported context. Rich old tools/runs/checkpoints/approvals/plans and native-session continuity remain intentionally excluded. F01 is not part of this tradeoff. |
+| D05 | Keep protocol V2 incompatibility?                              | Keep the version gate and deploy matching clients/servers. CORS permits the protocol header.                                                                                                                                                           |
+| D06 | Keep bounded portable summaries?                               | Keep the accepted 240-character per-item portable summary limit and separate 32,000-character legacy context budget unless fuller fidelity is now required.                                                                                            |
+| D07 | Keep compact mobile queue controls?                            | Mobile supports reorder/steer/cancel; active server queues still lack web's composer editor and thumbnails. New-task outbox editing is a different path. Keep as a surface choice unless parity is now wanted. F10 is independent.                     |
+| D08 | What happens to schedules bound to archived/deleted threads?   | Binding/upsert does not reject archived targets; later sends reject them, and recurring tasks stay enabled. Choose reject/disable behavior or deliberate waiting for unarchive. This is a branch-only lifecycle decision, not a missing main feature.  |
+
+## Cost and validation limits
+
+| ID  | What remains unproven                                                                                                                                                                | Next useful proof                                                                                                                                                               |
+| --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| V01 | Actual frame/byte savings from V2 coalescing and the workload impact of fallback snapshots. Source and focused tests establish bounds on live events, not end-to-end payload cost.   | Replay representative provider activity and large-thread reconnects; measure frames, bytes, and retained state. Keep persisted events intact.                                   |
+| V03 | Real interaction behavior across web, desktop, mobile, and remote/relay connections.                                                                                                 | An authorized integrated pass for attachments, queue edits, inherited links, and fallback resume. No browser/simulator permission was given for this audit.                     |
+| V04 | Latency of the deliberate startup corruption scan. It pages in groups of 500 and decodes each canonical row once, but still scans all 16 projection tables before command readiness. | Benchmark representative retained databases before choosing a different strategy. Preserve corrupt-row detection/recovery; do not label this the old F15 history-hydration bug. |
+
+Cost findings are based on concrete ownership, SQL, retention, or transport paths. No measured CPU, latency, heap, or billing multiplier is asserted. F06/F07 permit provider work to continue after intended shutdown, but this audit did not measure resulting spend. F21 is missing telemetry, not proof of excess spend. The old V1 transfer benchmark/report workflow remains deliberately removed; focused V2 wire tests are not an equivalent workload benchmark.

+| ------------------------ | ------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| Parent cross-cutting     | 19 file executions, 193 tests                                                   | Five `root-*-tests*.log` batches covering authorization, startup, WS helpers, coalescing/budgets, awareness, usage, attachments, title handling, native-command routing and launch guards.                              |

These mocked suites do not exercise real provider processes.                                                                          |

No simulator ran.                                                      |
+| Persistence audit probes | Six cases using real migration, allocator/projector, and policy implementations | [persistence-audit-probes.test.ts](persistence-audit-probes.test.ts). Passing means the asserted failures/state mismatches reproduced; it does not mean those bugs are fixed.                                           |
+| Provider audit probe     | One case through the actual Claude V2 adapter                                   | [provider-adapter-regression-probes.test.ts](provider-adapter-regression-probes.test.ts) and its [log](provider-adapter-regression-probes.log). A structured `api_error` result incorrectly emits completed/no failure. |
+
+The parent re-ran both audit probe files together after reviewing their code: all seven assertions passed in [reviewed-probes.log](reviewed-probes.log). This confirms the reproductions, not repaired behavior. Repeat runs are not counted as additional coverage.
+
+One initial test invocation accidentally discovered a frozen `.test.ts` copy under this audit directory. Its relative import failed while the actual three product suites passed. Copies were renamed to `.snapshot`, the manifest was updated, and the rerun passed. This was an audit setup failure, not a product regression.
+
+Current-head [CI Check](https://github.com/pingdotgg/t3code/actions/runs/33905624991/job/101129744766) fails formatting in seven files: `WorktreeMcpService.ts`, `EffectOutbox.ts`, `cursorSdkModel.ts`, two V2 architecture docs, `boundedThreadSnapshotHttp.ts`, and `threadSnapshotHttp.ts`. Generic tests and server shards 1/2 passed; server shard 3 was cancelled. Rust and release smoke passed. Web/mobile/macOS previews were skipped. Recent review comments since the previous audit cutoff were empty. These statuses apply to committed HEAD, not the uncommitted overlay.
+
+No repo-wide checks, dev servers, browser sessions, provider processes, production database writes, commits, pushes, PR creation, or external review comments were performed. Green focused tests do not contradict findings whose production trigger their fixtures omit. The full historical-manifest matrix and live client/provider validation remain incomplete.

Fixed findings are retained as closed rows so a later rebase audit can test them again. The recommendations do not authorize or implement new fixes.

+# Main and Orchestrator V2 feature map
+
+Comparison: committed V2 `8af5734365f7c45bc08b57066dbae42f9f7d4235` against initially fetched main `d7cf8aaa8d4fbcbdd523b4f4bc86fda5c47b4a70`, with uncommitted work reviewed separately. Seven late main commits through the final cutoff `f6db4206258b0ef30e8dd8949627acfd209bf338` are assessed as M09-M15. See [AUDIT.md](AUDIT.md) for findings, decisions, and evidence limits.
+
+“Retained” means the inspected implementation and its active caller have an equivalent path, not that every surface was exercised. “Shared” means the implementation matches the initial main; changed callers still need review. “Intentional” records an architectural choice rather than treating file deletion as feature deletion. Findings F01-F22 exclude closed IDs F02/F14/F15/F17. Main-only items M01-M15 are assessed separately for equivalent behavior or catch-up work.

+The production built-in registry includes Codex, Claude, Cursor, Grok, OpenCode, Antigravity, and ACP Registry. An older helper's shorter list is not the production registration path. The managed-driver initialization, settings hydration, catalog discovery, and auth paths were reviewed separately from per-turn adapters. See [providers.md](providers.md) for precise capability limits and line evidence.

+| Codex        | Pending/unavailable state until health check; auth/discovery; native resume/fork/from-turn/rollback; tool approvals; structured and async questions; native compaction; per-turn usage | No new committed parity defect found in reviewed scope. Local `turn/diff/updated` opt-out is not committed and has focused coverage.             |
+| Claude       | Registry/auth; resume/fork/from-turn/rollback; approvals/questions; slash-command attachment ordering; native compaction; usage                                                        | F11 Read-image presentation; F20 dead-turn result classification. SDK 0.3.260 is present, but its terminal-reason handling was not fully ported. |
+| Cursor       | Accepted SDK implementation; auth/model/skills discovery; resume; mode mapping; interrupt-restart                                                                                      | D03: fork/rollback/approval/question capabilities are explicitly unsupported. F08: background metadata uses unrestricted agent mode in real cwd. |
+| OpenCode     | Local/external server configuration; access policy; workspace skills through SDK; resume/fork/from-turn/rollback; native compaction; root stop timeout                                 | F06 descendant Stop failures; F07 external teardown; F18 clean SSE EOF; F19 reply hangs; F21 token accumulation.                                 |
+| Grok         | Registered ACP specialization; auth/catalog; session loading; permission and question extensions; interrupt/teardown                                                                   | Unsupported native fork/rollback/usage are explicit protocol limitations. No new concrete regression established.                                |
+| Antigravity  | Registered official ACP agent; managed health/profile auth; negotiated capability/catalog updates; subagent translation; constrained metadata helper                                   | No new concrete server parity defect established. Capability limits follow the runtime; no real sign-in/provider session was launched.           |
+| ACP Registry | Instance-specific command/auth discovery; negotiated loading/fork/model/MCP capabilities; permissions/questions; interrupt/teardown                                                    | Native rollback and text generation are explicitly unsupported; live request IDs cannot be resumed after process loss.                           |

+| Provider availability                | Codex driver uses `makePendingCodexProvider`, with unchecked `installed: false`                                               | Dropped-patch lead rejected; behavior was absorbed.                                                                              |
+| Cwd-specific catalogs                | Web and mobile request selected-workspace catalogs; Claude also scans for execution                                           | Prior broad V02 concern closed. No narrower CLI-only failure proved.                                                             |
+| Bundled current-model classification | Initial main manifest is retained; remote refresh can update it independently                                                 | M12: latest main adds `gpt-6-astra`; offline fallback still labels it legacy.                                                    |
+| Native compaction                    | Launch guards recognize native commands; run execution calls adapter `compactThread`; unsupported providers reject explicitly | Retained; focused launch/execution and adapter tests pass.                                                                       |
+| Logout / session teardown            | Auth service passes V2 session stop to controller; native logout command is guarded during launch                             | Shared path retained. OpenCode external cleanup still has F07.                                                                   |

Cursor boundary F08 is independent.                                                      |
+| Usage dashboard/pricing/limits       | Shared readers, pricing, proxy-account deduplication, limits and reset-credit APIs are retained                               | Inspected shared source and focused usage tests pass. F21 concerns per-turn OpenCode telemetry, not demonstrated dashboard loss. |
+| Provider text/event logging          | V2 protocol-event log infrastructure replaces older orchestration logging                                                     | Bounded logging work retained; dirty event logger work reviewed separately. No production-volume benchmark run.                  |

+Desktop uses the web UI, so a web fix normally needs the same renderer there plus any native IPC boundary. Mobile has its own React Native call sites and cannot be inferred from web parity.

+
+## Local work and coverage limits
+
+Local changes were not attributed to committed HEAD. The dirty overlay includes narrower settlement and visit reads plus migration 059 indexes, cheaper local Git status, visibility-leased palette PR/VCS data, stable desktop topology identity, Codex notification opt-out, logger bounds, awareness coalescing and retries, and the Expo notification synchronization patch. Focused local tests passed; no new concrete regression was found in the inspected changes. F01/F03-F13/F16 and the new findings remain as documented.
+
+Other work continued during the audit. Later awareness source/tests, projection-settlement tests, and three internal docs are captured separately in `worktree-drift`. The awareness changes were re-read; they retain bounded retries and stop retrying on disabled/unlinked configuration. Hashes and paths identify what was reviewed and tested without overwriting anyone else's work.
+
+All seven production providers, the V1-to-V2 registration boundary, WebSocket/HTTP/live-CLI/offline-CLI project lifecycle, web/desktop/mobile client callers, and local/remote protocol boundaries were included in source review. The initial eight unmerged main commits and seven late arrivals were inspected individually. The initial 240-commit incoming inventory and 991-file tree comparison guided the review; the closing incoming inventory has 247 commits, with final file counts recorded in `closing-references.json`. Equality or a matching patch was not treated as sufficient proof of feature parity after a caller moved. The client report additionally traces six recent ports through actual V2 callers: file-backed image readiness, hidden terminal visibility, static chat status, failed preview-capture cleanup, Antigravity unknown-auth behavior, and sidebar multi-select unpin. All six are retained.
+
+No live provider, browser, simulator, packaged desktop app, full release build, or repository-wide test suite ran. Windows/Linux native execution, full historical migration stopping points, actual provider stream recovery, end-to-end relay expiry, and workload-level CPU/heap/frame measurements remain outside this audit's proof. Marketing-only/shared unchanged files received inventory review rather than a separate UI audit.

+# Client parity and regression audit, 2026-09-04
+
+## Result
+
+The committed client surface still has two previously reported correctness defects: F09 silently drops newly attached generic files from queued-message edits, and F10 hides every non-image attachment in the mobile V2 feed. F02 and F17 are fixed in committed HEAD. D02 remains an unresolved ownership decision, and D07 remains the deliberate compact mobile queue surface even after the large composer port.
+
+I found four additional differences from the frozen main tree. Three are current-main-only performance fixes that have not yet been incorporated, not rebase regressions: immediate thread-stream release from [#9740](https://github.com/pingdotgg/t3code/pull/9740), indexed terminal metadata from [#9747](https://github.com/pingdotgg/t3code/pull/9747), and the bounded mobile parsed-review cache from [#9749](https://github.com/pingdotgg/t3code/pull/9749). The fourth is the current-main-only trailing-activity fold fix from [#9739](https://github.com/pingdotgg/t3code/pull/9739). Main lag is kept separate from lost earlier ports throughout this report.

+Committed evidence was read with `git show <frozen-sha>:<path>`. Local-only evidence came from the `.snapshot` files named by `worktree-manifest.json`. All scoped overlay, manifest, and live-worktree hashes matched before the local tests ran.

+## Open committed findings
+
+### F09, P1: queued-message edits still discard newly attached generic files
+
+`apps/web/src/components/ChatView.tsx:6596-6610` reads both `images` and `files` from the real composer. Once queued edit mode is active, however, the save path copies only `composerImages` into `newEditImages` at `:6644-6649`. Its attachment-only guard checks original attachments and new images, but not `composerFiles`, at `:6650-6655`. It uploads only `newEditImages` at `:6659-6667`, sends original attachments plus those image uploads at `:6668-6677`, then clears the whole edit draft at `:6684-6688`.

+The actual caller does not disable generic attachment input during editing. `ChatView` points `ChatComposer` at the queued-edit draft and passes ordinary attachment capability props at `:8400-8410`; the queue editor is selected at `:8421-8430`. The editor even renders the original attachment set at `:8508-8510`. Therefore:
+
+- A file-only new edit with no text, original attachment, or image cannot be saved because the guard returns.
+- If text or an image makes the edit sendable, the command succeeds without the generic file and the subsequent draft clear destroys the local selection.
+- If another client starts or cancels the queued run first, the recovery effect calls the file-capable `moveComposerPromptAndImages` helper, but its dirtiness check ignores files at `:3540-3547`. A file-only unsaved edit therefore takes the clearing branch at `:3555-3560`. The helper itself demonstrably supports `source.files` and writes them to the destination in `apps/web/src/composerDraftStore.ts:3911-4000`; the caller never reaches it for that state.
+
+Existing committed queue tests verify thumbnails, optimistic-row removal, and keeping the source row visible while editing. They do not submit a generic file or exercise file-only external-start recovery. Main has no equivalent queued editor, so this is a bug in the V2 branch feature rather than a lost main port.
+
+### F10, P1: mobile V2 feed still filters out non-image attachments
+
+`apps/mobile/src/features/threads/ThreadFeed.tsx:1508-1516` derives the attachment list for every message with `attachment.type === "image"`. Both user and assistant branches then contain correct file and unknown renderers at `:1569-1590` and `:1657-1678`, but those branches are unreachable because the shared list has already discarded files, PDFs, videos, and unknown attachment kinds.
+
+Frozen main uses `message.attachments ?? []` without the filter at `apps/mobile/src/features/threads/ThreadFeed.tsx:1407-1414`. Mobile attachment upload and persisted V2 projections can therefore contain a valid non-image attachment that survives transport but has no visible message chip or preview entry after reopening the thread. This remains a committed branch regression, independent of D07's compact queue controls.
+
+## New provisional findings
+
+### CLIENT-01, P1 performance: shared thread streams remain live for five minutes after their last consumer
+
+This is a current-main-only parity gap, not a rebase regression. In committed HEAD, `packages/client-runtime/src/state/threadRetention.ts:1-3` explicitly retains stream-backed state for five minutes. Every derived detail atom uses that TTL at `packages/client-runtime/src/state/threadDetail.ts:20-73`, and the raw `environment-thread-state` atom also uses it at `packages/client-runtime/src/state/threads.ts:687-696`.
+
+Trigger: open a thread detail or mount any detail/status consumer, then navigate away. The atom remains mounted during its idle TTL, so the `subscribeThread` stream and its in-memory projection continue receiving events for up to five minutes. Repeated navigation can accumulate one live stream per recently visited thread on web, desktop, or mobile. Remote and relay connections pay the same unnecessary event traffic and server projection work. No multiplier or measured byte count is claimed.
+
+Frozen main's [#9740](https://github.com/pingdotgg/t3code/pull/9740) splits these lifetimes. Derived and live atoms use `Atom.setIdleTTL(0)` in `threadDetail.ts:75-82` and `threads.ts:827-844`, so the last consumer closes the stream immediately. A distinct resume atom retains only a warm snapshot/cursor for five minutes at `threads.ts:816-825`. Main's behavioral tests close the first stream at last unmount and reopen from the retained sequence without another HTTP load. The branch's existing `threads-atoms.test.ts:12-22` instead codifies the old five-minute live retention.
+
+This mechanism is separate from live-event coalescing and snapshot size. The committed server now calls `coalesceThreadLiveStream` at `apps/server/src/ws.ts:813-834`, which reduces update frequency while a stream exists. It does not end unused streams. F16 is also separate: it concerns an unbounded single fallback snapshot outside the coalesced event path.
+
+### CLIENT-02, P2 performance: each terminal-status consumer rescans and resorts all environment metadata
+
+This is also a current-main-only parity gap. `apps/web/src/state/terminalSessions.ts:51-82` filters, maps, allocates, and numerically sorts the entire environment terminal array inside every `useKnownTerminalSessions` consumer whenever the metadata snapshot changes. `useThreadRunningTerminalIds` immediately performs another selection at `:85-90`.
+
+The operation is not confined to one chat view. It is called from sidebar rows (`apps/web/src/components/Sidebar.tsx:826` and `:1763`), legacy sidebar rows (`apps/web/src/components/LegacySidebar.tsx:386`), every command-palette thread row through `ThreadRowTrailingStatus` (`apps/web/src/components/ThreadStatusIndicators.tsx:671-675` and `CommandPalette.tsx:1189`), and several `ChatView` consumers. A terminal metadata update therefore does repeated O(terminal count) scans, conversions, sorts, and fresh-array publication across the number of mounted rows. The local command-palette patch bounds VCS and linked-PR reads only; trailing terminal consumers remain on this committed implementation.
+
+Frozen main's [#9747](https://github.com/pingdotgg/t3code/pull/9747) builds one WeakMap-backed ordered index per immutable metadata snapshot, groups summaries by thread once, and reuses unaffected group/session identities in `apps/web/src/state/terminalSessions.ts:20-121`. Its test at `terminalSessions.test.ts:152-170` verifies that 40 thread selectors cause exactly one traversal of the 40-entry source array. The branch has no equivalent selector or test.
+
+### CLIENT-03, P1 performance: mobile parsed review diffs are retained and prewarmed without a bound
+
+This is a current-main-only parity gap. Committed `apps/mobile/src/features/review/reviewState.ts:90-95` creates a keep-alive family entry for every `threadKey:sectionId`. `getCachedReviewParsedDiff` stores both the normalized source string and full parsed structure in that permanent entry at `:259-281`. `useReviewDiffPrewarming` collects every loaded non-selected section at `apps/mobile/src/features/review/useReviewDiffPrewarming.ts:58-65` and schedules all of them at `:70-93`.
+
+Trigger: browse review sections across multiple threads, especially large diffs. Each distinct section can retain its source and parsed representation for the app-registry lifetime, and idle prewarming eagerly creates entries for all loaded sections. The native review adapter is keyed by these parsed objects, so permanent parsed ownership also prevents those associated native-data entries from becoming collectible. On memory-constrained mobile devices, the retained working set grows with review history rather than an explicit budget. No heap-size estimate is claimed.
+
+Frozen main's [#9749](https://github.com/pingdotgg/t3code/pull/9749) replaces the family with one registry-local LRU-style cache capped at eight diffs and 4 MiB of source characters (`reviewState.ts:90-104`, `:291-327`). It skips oversized inputs and prewarms only nearby sections that fit the same budget (`useReviewDiffPrewarming.ts:38-99`).
+
+### CLIENT-04, P2 presentation: one ordinary late activity remains outside an otherwise settled fold
+
+This is the fourth current-main-only gap. Committed `apps/web/src/components/chat/MessagesTimeline.logic.ts:639-643` deliberately leaves work arriving after the terminal assistant message visible. The fold loop at `:719-731` skips every non-compaction entry after that message, including the common case where exactly one successful ordinary tool activity lands late.
+
+The consequence is a detached tool row below a settled assistant response even though the rest of that turn is behind its `Worked for ...` fold. Failures, interrupted work, persistent resources, and multi-row trailing groups should remain explicit; the concrete mismatch is the single non-failed activity case. Frozen main's [#9739](https://github.com/pingdotgg/t3code/pull/9739) admits exactly that one case into the fold while retaining the safeguards for failures and larger groups. This is user-visible clutter, not lost data.

Inspector reasoning is different and explicitly builds a ref from `projectedItem.sourceThreadId` at `V2ItemInspector.tsx:132-142`. Mobile builds all Markdown link/image handlers from the active screen `environmentId`, `threadId`, and `workspaceRoot` at `ThreadFeed.tsx:2139-2180` and `:2256-2303`. Thus ordinary inherited message/plan links still resolve against the active fork, not the source worktree. Main has no inherited-row oracle. Decide source-history ownership versus current-fork ownership before changing it. |
+| D07 | **Retained intentional difference** | The active-thread mobile queue still exposes reorder, steer, and cancel only in `ThreadQueueControl.tsx:18-149`. Shared workflow state carries queued attachments (`packages/client-runtime/src/state/threadWorkflows.ts:21-25`, `:100-113`), but the mobile row destructures only `run` and `text` and renders no edit action or thumbnail. The large composer port added full editing for pending new-task outbox entries in `NewTaskDraftScreen`, not for server-projected queued runs. This is a surface choice, not a new regression.                                                                                                                                                                                                         |
+
+Root's cross-domain status is recorded without re-auditing ownership here: F13 remains an error-without-timestamp settlement case, F14 improved, F15 is fixed, and F16 remains open. F15's separate startup verification scan is an accepted performance tradeoff. The client-side F16 consequence is precise: committed `packages/client-runtime/src/state/threads.ts:643-647` sends no `turnLimit`, and a fallback snapshot replaces state without a usable progressive-history cursor. The healthy bounded HTTP path and committed live-event coalescer are not affected by that statement.
+
+## Old bot lead disposition
+
+- **Stopped/cancelled tools shown as green Completed: rejected.** `apps/web/src/session-logic.ts:481-498` maps cancelled and interrupted V2 items to `stopped`. `workEntryIndicatesToolSuccess` excludes `stopped` and `idle` at `:270-285`; the neutral-status path handles the remainder. A settled neutral row may be omitted by folding, but the current source does not relabel it as a successful green completion.
+- **Server-thread environment selector appears actionable but can no-op: source-confirmed in both trees, not elevated as a V2 parity finding.** Committed `ChatView.tsx:3358-3374` allows the callback only when `draftId` exists, while `:8539-8545` passes it whenever multiple environments exist. An empty server-backed thread with no live runtime can therefore render an unlocked selector whose callback returns. Frozen main has the same shape at `ChatView.tsx:3145-3165` and `:8047-8053`. It is a shared pre-existing edge case, most reachable through externally created/imported/failed empty threads because ordinary new-thread navigation uses a draft route.

+| [#9739](https://github.com/pingdotgg/t3code/pull/9739), fold one late activity                  | **Missing.** All ordinary post-message activity stays outside the fold.                                                                                                                                                                      | CLIENT-04, main-only catch-up required.                                     |
+
+Fresh checks against earlier post-audit main work also found equivalent branch-specific implementations rather than treating file differences as omissions. Streaming assistant row reuse from [#9725](https://github.com/pingdotgg/t3code/pull/9725) is represented by `deriveMessagesTimelineRowsWithState` and V2 provenance-aware streaming replacement in `MessagesTimeline.logic.ts:1331-1429` and `session-logic.ts:844-880`. Thread-list identity reuse from [#9716](https://github.com/pingdotgg/t3code/pull/9716) is present through the WeakMap-backed scoped-shell cache and stable grouped arrays in `packages/client-runtime/src/state/threadShell.ts:34-170`. Recent desktop browser-profile/import, SSH-resolution, and screenshot-failure IPC contracts and handlers are also present in frozen HEAD. These are not findings.
+
+## Bounded six-port caller sweep
+
+This follow-up was source-only against frozen committed HEAD. It traces the active V2 callers but does not claim runtime or rendered-UI verification. All six named main changes retain equivalent behavior; differing files reflect later V2 work rather than dropped ports.
+
+- [#9713](https://github.com/pingdotgg/t3code/pull/9713), file-backed mobile image drafts: **retained**. `attachmentUpload.ts:192-226` reads file-backed images when the legacy inline path needs bytes, and `:312-322` waits for that conversion before returning `ready`. The immediate new-thread caller waits on `prepareTurnAttachments` at `use-project-actions.ts:83-107` and sends only `prepared.attachments` at `:131-151`. The offline and queued caller does the same at `use-thread-outbox-drain.ts:118-155`, `:697-706`, and `:874-884`. `projectThreadStartTurn.ts:15-53` no longer has a fallback that treats an absent inline `dataUrl` as ready.
+- [#9718](https://github.com/pingdotgg/t3code/pull/9718), hidden terminal rendering: **retained active caller**. The V2 right-panel terminal passes `rightPanelOpen` into `PersistentThreadTerminalPanel` at `ChatView.tsx:7910-7927`, and that panel passes `visible` into `ThreadTerminalDrawer` at `:1165-1283`. The otherwise shared drawer calls the terminal surface's visibility gate and suppresses hidden focus and fit work at `ThreadTerminalDrawer.tsx:438-489` and `:913-943`; both split and single viewports receive the flag at `:1492-1543`. The changed `ChatView` layout did not strand the unchanged terminal gate.
+- [#9709](https://github.com/pingdotgg/t3code/pull/9709), continuous chat status animation removal: **retained**. The running update icon is static at `ComposerServerUpdateStatus.tsx:9-20`. V2 setup, compaction, working, and thinking rows render static text or icons at `MessagesTimeline.tsx:2541-2584`, and `LiveActivityRow` has no shimmer overlay at `:2588-2608`. The removed `live-activity-focus` and ultrathink animation utilities have no active caller or definition in frozen HEAD. The remaining timer text update is not a CSS animation.
+- [#9127](https://github.com/pingdotgg/t3code/pull/9127), desktop preview-capture failure unlock: **retained end to end**. Desktop reports `screenshotFailed` when crop capture fails at `apps/desktop/src/preview/Manager.ts:2473-2487`, and the IPC schema carries it at `packages/contracts/src/ipc.ts:936-947`. The renderer bounds its own crop conversion to five seconds at `apps/web/src/lib/previewAnnotation.ts:113-147`, keeps the annotation without the crop, and always clears the active pick in `PreviewView.tsx:580-630`. A failed capture cannot leave the composer locked on this path.
+- [#9647](https://github.com/pingdotgg/t3code/pull/9647), Antigravity restart sign-in behavior: **retained active callers**. `ChatComposer.tsx:1644-1651` still uses `getAntigravitySendBlockReason` for the actual send gate. The helper permits `auth.status === "unknown"` after validating installation and a selected model at `ChatView.logic.ts:415-428`; it blocks only explicit unauthenticated state. The active banner also suppresses the installed Antigravity warning while auth is unknown at `ProviderStatusBanner.tsx:9-31`, and `ChatView.tsx:3279-3292` uses that result.
+- [#9651](https://github.com/pingdotgg/t3code/pull/9651), sidebar multi-select unpin: **retained**. The active multi-select context-menu caller filters selected rows to pin-capable, currently pinned threads and adds `Unpin (k)` at `Sidebar.tsx:2978-3019`. Selecting it calls `attemptUnpin` for exactly that filtered set and clears selection at `:3101-3107`. `Sidebar.logic.ts:209-218` omits the action when the pinned count is zero.
+
+No finding was added for this six-item sweep.
+
+## Late-main addendum
+
+Main advanced after the frozen comparison to `bc03c3640d6d3bb44e5fb477bfd78d7484cd0e00`. The branch HEAD and overlay did not move. These two items are late-main catch-up gaps, not claims that an earlier port was lost.
+
+- **M09, defer the mobile file highlighter from [#9752](https://github.com/pingdotgg/t3code/pull/9752): missing.** Frozen HEAD wraps every valid `ThreadFileScreen` in `ReviewHighlighterProvider` at `ThreadFilesRouteScreen.tsx:825-943`. The provider immediately calls `useReviewHighlighterState` at `ReviewHighlighterProvider.tsx:11-19`, whose mount effect prepares the engine and initial language set at `reviewHighlighterState.ts:164-176`. This happens for image, video, browser-preview, Markdown-preview, and source routes even though only `SourceFileSurface` consumes `sourceHighlightAtom`. That real consumer already starts `highlightSourceFile` lazily through `sourceHighlightingState.ts:29-50`. The late main commit removes the redundant route-wide provider and manager, so the branch still pays highlighter startup on file routes that do not need syntax highlighting.
+- **M11, defer history image URLs from [#9760](https://github.com/pingdotgg/t3code/pull/9760): missing.** Frozen `ChatView` walks every loaded user message attachment at `ChatView.tsx:2910-2919`, turns the full set into asset resources, and calls `useAssetUrls` at `:2959-2977`. The resulting URLs are projected into the whole timeline at `:3072-3130`, before virtualization determines which message rows are mounted. The active V2 `UserTimelineRow` at `MessagesTimeline.tsx:1381-1445` merely consumes those prefilled URLs. The late main commit keeps only pending local-preview handoffs at chat scope and moves image resource selection plus `useAssetUrls` into each mounted user row. The branch therefore still requests signed URLs for offscreen history, including IDs collected from non-image user attachments. This is a post-freeze performance gap, not an old-regression finding.

+
+## Dirty overlay, local-only review
+
+No new concrete defect was found in the scoped dirty overlay. These are not committed fixes and do not change the committed status of any finding above.
+
+- **Command palette / thread indicators.** The snapshot passes the existing thread change-request snapshot into each leading status row. `ThreadRowLeadingStatus` observes its containing result with the shared sidebar lease, gates linked-PR and VCS queries on near-viewport visibility, retains the last live value by environment/worktree key, and falls back only to a same-branch, non-linked snapshot. The local 128-row test verifies zero offscreen reads, eight reads for the first visible set, eight more after moving visibility, and retained cached badges. It does not cover the trailing terminal query, which is why CLIENT-02 remains.
+- **Desktop local topology.** `desktopLocal.ts.snapshot` keeps the last array identity when a bridge returns fresh objects with equal `id`, label, distro, HTTP URL, WS URL, and bootstrap token. It publishes a new identity when any field changes and keeps the bridge-less empty array stable. Tests cover every compared field.
+- **Expo notifications patch.** The patch protects delegates and pending responses with `NSLock`, snapshots delegate lists before callbacks, appends a response before releasing the lock, and removes only the exact handled response identities afterward. That ordering covers both interleavings between delegate registration and delivery and preserves responses created during a replay callback. Workspace patch mapping and lockfile hash wiring match the patch. The native test compiles the installed patched Swift source with ThreadSanitizer; no simulator was launched.
+
+## Tests and limitations
+
+Detailed output is in `clients-focused-tests.log`.
+
+- The six-port sweep and M09/M11 addendum are source-only. No tests were rerun for this follow-up.
+- **Committed-source evidence:** 3 files, 21 tests passed. Before execution, all three live files had SHA-256 hashes identical to frozen committed HEAD. These cover queue ordering/capability presentation and web queue-row behavior. They do not cover F09 submission or D02 routing.
+- **Local-only overlay evidence:** 5 files, 60 tests passed. The four requested filter strings selected one additional committed `.test.tsx` file because Vite+ file filtering is substring-based; it is not counted as separate intended coverage. The scoped live files matched the suffixed frozen snapshots and manifest hashes before execution. The only warning was `react-test-renderer` deprecation.
+- The root batch's earlier copied-test import failure was audit-artifact discovery noise. All frozen overlay test copies now end in `.snapshot`; no copied audit test ran in this client batch.
+- No browser, desktop app, provider, server, simulator, or real UI renderer was launched. No visual behavior is claimed for update-notice layout, attachment chips, folds, or Markdown interaction.
+- No live T3 userdata was opened or mutated. No product code or existing test was edited. No repo-wide command, commit, push, GitHub action, or review comment was performed.
+- Source inspection proves the stated control/data paths. It does not provide measured frame sizes, heap growth, CPU percentages, or end-to-end remote latency.

+# Cross-cutting review, 2026-09-04
+
+Committed target: `8af5734365f7c45bc08b57066dbae42f9f7d4235`. Main: `d7cf8aaa8d4fbcbdd523b4f4bc86fda5c47b4a70`. The worktree is changing independently; frozen local copies have a `.snapshot` suffix and are listed in `worktree-manifest.json`. These are review artifacts, not product changes.
+
+## Prior findings
+
+**F12 remains open, P2.** Initial automatic titles still make one request. [ThreadTitleRegenerationService.ts](/Users/julius/.t3/worktrees/codething-mvp/t3code-7f11a674/apps/server/src/orchestration-v2/ThreadTitleRegenerationService.ts:223) calls `generateThreadTitle`, then catches non-interruption failures as completion at line 236 and clears the request marker. The shared text-generation layer adds no retry. Main's `ProviderCommandReactor.ts:963` retries initial generation twice with exponential backoff, from [#8087](https://github.com/pingdotgg/t3code/pull/8087). A transient typed provider error therefore leaves the fallback title until manual regeneration. The existing failure test deliberately dies, asserts one call, and verifies cleanup; it does not test transient typed failure followed by success. Restore bounded retries for initial titles while retaining stale-request guards and cleanup. Source is unchanged between the preceding audited revision and this committed target.
+
+**F16 remains open, P1 for large histories.** [ws.ts](/Users/julius/.t3/worktrees/codething-mvp/t3code-7f11a674/apps/server/src/ws.ts:867) still obtains `getThreadSnapshot`, projects the entire result, and emits it as one socket snapshot. Invalid cursors and reconnect ranges above 128 events or 1 MiB use this function. A cold HTTP snapshot failure uses it too. `ThreadManagementService` delegates this to the full projection-store snapshot, despite having a separate windowed snapshot method. Per-item wire truncation does not cap the number of rows. [threads.ts](/Users/julius/.t3/worktrees/codething-mvp/t3code-7f11a674/packages/client-runtime/src/state/threads.ts:301) accepts the full snapshot and resets progressive history metadata. Main's `ws.ts:1676` forwards the client's `turnLimit` when obtaining the fallback snapshot. The existing healthy HTTP path is bounded; this finding concerns fallback. Route fallback through the bounded query/budget path and carry a valid history cursor. No latency or memory multiplier is claimed.
+
+**V01's missing-coalescer concern is addressed in committed code.** `ws.ts:827` now wires `coalesceThreadLiveStream`. The new implementation combines repeated running tool updates by thread, run, and stable item ID in a 50 ms window. Lifecycle/message boundaries flush survivors in sequence order. Its tests exercise independent calls, terminal boundaries, cancellation, and retained-buffer limits. The separate `LiveStreamBudget` also limits queued and unacknowledged live events. This does not fix F16 because the snapshot frame is produced outside that bounded event path. Actual provider-workload byte/frame comparisons remain unmeasured.
+
+**D01 is still an explicit deferral.** [ServerEnvironment.ts](/Users/julius/.t3/worktrees/codething-mvp/t3code-7f11a674/apps/server/src/environment/ServerEnvironment.ts:230) withholds `serverUpdateThreadContinuation` and explains that V2 recovery terminalizes running work instead. Main's continuation feature from [#9167](https://github.com/pingdotgg/t3code/pull/9167) is not provided. This is a documented product decision, not evidence of a careless conflict resolution.
+
+## Main lag and retained boundaries
+
+There are eight main-only commits. The [main-only inventory](main-only-commits.txt) is separate from old porting failures. In particular, [#9748](https://github.com/pingdotgg/t3code/pull/9748) adds an 8 MiB terminal-history cap, bounded Unicode-safe tail reads, and protection against giant partial lines. This branch still limits terminal history by 5,000 lines only and reads the entire saved history before capping it at `terminal/Manager.ts:1494`. A long line remains unbounded in memory, storage, and attach snapshots. That change is independent of V2 and should be incorporated when catching up with main.

+| PR and base                              | [#2829](https://github.com/pingdotgg/t3code/pull/2829) targets main and has the reviewed head. Main is eight commits ahead of the merge base; there are 333 branch-only commits and 991 changed files in the final-tree comparison.                                                                                                                                                                                                                                      |
+| Incoming main inventory                  | 240 commits since the previous main reference. 64 touch only files now identical to main; 176 touch at least one differing file. File equality is a triage aid, not proof of a caller being retained.                                                                                                                                                                                                                                                                    |
+| Rebase patch inventory                   | The range comparison has 265 equal patches, 64 changed pairs, three unmatched old patches and four unmatched new patches. Two unmatched pairs are integration/lint bookkeeping. The unmatched old Codex availability patch is absorbed: `CodexProvider.ts:489-525` still initializes an unchecked provider with `installed: false`. The prior audit tip maps exactly to `96aff3564b3`; the two subsequent commits contain the new resource work and main reconciliation. |
+| Protocol and CORS                        | Protocol V2 negotiation remains explicit, and `httpCors.ts` permits the protocol header. Renamed/new RPCs retain explicit auth-scope entries. Focused tests pass.                                                                                                                                                                                                                                                                                                        |
+| Remote identity, credentials and pairing | Shared auth implementations apart from the RPC mapping, and cloud credential refresh code, match main. This includes the pairing read-model and refresh-without-disconnect changes. No live relay or expiry flow was exercised.                                                                                                                                                                                                                                          |
+| Long delegated IDs                       | Both environment HTTP routing and relay HTTP routing allow 512-character parameters. The relay worker supplies that router configuration.                                                                                                                                                                                                                                                                                                                                |
+| Relay push and decoding changes          | Main's stalled-push bounds and decoding changes are in identical relay files outside the V2 awareness adapter.                                                                                                                                                                                                                                                                                                                                                           |
+| Background metadata prompts and pricing  | Shared text-generation prompts/dispatcher, usage readers and cloud code match main. Provider-specific permissions and token translation are reviewed separately.                                                                                                                                                                                                                                                                                                         |
+| Checkpoint summaries                     | Shared `CheckpointStore` matches main, including avoiding full patches when only summaries are needed. F03 concerns the V2 baseline query, not that shared implementation.                                                                                                                                                                                                                                                                                               |
+| Automatic project pulls and PR refresh   | The opt-in project setting reaches `VcsStatusBroadcaster`'s policy and startup `autoPullProjects`. V2 run execution invokes the cached `refreshAfterTurn` observer, and checkpoint finalization refreshes branch PR status. These replacements remain wired to the shared implementations.                                                                                                                                                                               |
+| Desktop and service launch               | Server bundle still includes both the main binary and service launcher. The only differing production Electron file has a type annotation in the Tailscale fallback, with no behavioral change. Web findings still affect desktop. No packaging or native runtime was launched.                                                                                                                                                                                          |
+| Performance CI                           | The V1-specific transfer-report workflow was deliberately removed by commit `103f1e6cd22`. Its commit message calls for a V2 replacement. A focused V2 wire regression script now exists, but the old built-app benchmark/report is not restored. Keep this distinction when claiming performance verification.                                                                                                                                                          |
+
+## Additional lifecycle question
+
+The old bot observation about archived scheduled-task targets still has a valid source path, but it is not a main-to-V2 regression because main has no equivalent scheduled-task service. `OrchestratorMcpService.ts:953` accepts the current thread as a schedule target without checking whether it is archived, and the generic scheduled-task upsert does not validate its target. Later, `ThreadManagementService.ts:483` rejects sends to archived threads. Recurring tasks retain their enabled state and compute the next occurrence after each failure. Archiving or deleting an existing bound target raises the same lifecycle question. Decide whether to disable such schedules, reject new bindings, or keep schedules enabled for later unarchive. No scheduling action or live provider was invoked for this audit.
+
+## Late main arrivals
+
+While the reviewed branch and local source stayed unchanged, `origin/main` advanced to `bc03c3640d6d3bb44e5fb477bfd78d7484cd0e00`. The four new commits are recorded in `main-late-arrivals.txt`; M09-M12 in the consolidated report cover them. The original frozen-main comparison and its eight missing commits remain reproducible.
+
+**M12, bundled model classification.** [#9762](https://github.com/pingdotgg/t3code/pull/9762) adds `gpt-6-astra` to the Codex `currentModels` list and advances the bundled manifest timestamp. The branch's manifest still matches the earlier main version. `ModelManifest.ts:210-221` classifies built-in models missing from that list as legacy. This affects the bundled/offline fallback: the existing runtime manifest refresh can obtain the updated main file and compensate online. It is not evidence that the provider cannot execute the model or that model discovery is absent. Incorporate the small data update during main catch-up.
+
+The parent independently checked OpenCode's installed SDK SSE generator: `dist/v2/gen/core/serverSentEvents.gen.js:117` exits the stream loop on normal completion. A clean response-body EOF does not automatically resubscribe, which supports F18's trigger. The adapter finding remains source-backed, without a timing-based absence test.
+
+Three final UI commits arrived before the cutoff was set at `f6db4206258b0ef30e8dd8949627acfd209bf338`. The parent reviewed these directly:
+
+- **M13, proactive diff activation, [#9753](https://github.com/pingdotgg/t3code/pull/9753).** V2 `ChatView.tsx:4261-4275` opens a diff whenever a completed run has any checkpoint summary and the workspace is a Git repository. It does not check whether the active surface is a pull request or whether the checkpoint is ready and nonempty. `threadCheckpoints.ts:29-51` preserves empty-file and non-ready summaries, so the active caller can replace a PR panel with an empty or unavailable diff. Main's new decision helper rejects those cases and preserves deferred loading. Adapt it to V2's `runId` summaries.
+- **M14, sidebar background prominence, [#9759](https://github.com/pingdotgg/t3code/pull/9759).** V2 `Sidebar.tsx:866-893` lets unread/woken state override dimming even while a thread is still working. Main dims unselected/unfocused working or monitoring rows regardless of unread completion, while retaining unread/wake prominence for ready and action-required states. Port the presentation rule using V2 statuses. This is visual policy catch-up, not lost conversation data.
+- **M15, automatic-pull reset affordance, [#9763](https://github.com/pingdotgg/t3code/pull/9763).** `ProjectSettingsPanel.tsx:989-999` still renders the working on/off switch without the new reset button. Main adds a reset action that calls the existing setter with `false`. The feature and its reverse operation already work; only the standard reset affordance is absent.
+
+The initial eight main-only commits plus these seven arrivals total 15 main-only commits at the final cutoff. No later main revision is included in this audit.
+
+## Focused checks and limitations
+
+- `root-contract-tests.log`: 6 file executions, 41 tests passed, covering WS compatibility, startup, RPC authorization, title handling, live coalescing, and wire projection.
+- `root-budget-awareness-tests-rerun.log`: 3 file executions, 28 tests passed, covering live-stream budgets and shared/local awareness behavior.
+- `root-resume-tests.log`: 3 file executions, 25 tests passed, covering resume decisions, active/archive shell streams, and HTTP contracts. The resume tests verify the fallback decision, not a bounded end-to-end fallback snapshot.
+- `root-usage-attachments-tests.log`: 5 file executions, 38 tests passed, covering usage readers/pricing/proxy limits, attachment claims, and metadata prompts.
+- `root-native-command-tests.log`: 2 file executions, 61 tests passed, covering V2 run execution and launch behavior, including native compaction routing and logout guards.
+- The first awareness run also selected a frozen audit copy because Vitest's file filter matched its suffix. Its import failure was an audit-artifact discovery problem; the three actual suites passed. Frozen files were renamed with `.snapshot`, and the rerun passed. No product source was changed to resolve this.
+- These are focused tests on the current worktree, including its local awareness work. They do not establish correctness for every client, provider, upgrade history, or fallback transport.
+
+Current-head [CI Check](https://github.com/pingdotgg/t3code/actions/runs/33905624991/job/101129744766) fails formatting in seven files. The generic test job and server shards 1 and 2 passed; server shard 3 was cancelled. Release smoke and Rust passed; web/mobile/macOS preview builds were skipped. The [captured metadata](pr-metadata.json) and [failed log](ci-check-failure.log) retain exact evidence. CI does not cover the uncommitted overlay. No repo-wide check, browser, simulator, dev server, live-provider validation, production database write, commit, push, or review comment was performed.

+Prior audit HEAD: `d2f1f511f4cc833bc930d6c355cd0f9b61e835a0`
+
+This audit is limited to schema upgrades, legacy import, projections, startup and recovery, outbox behavior, checkpoint diff and rollback, project and thread lifecycle boundaries, auto-settlement and snooze behavior, durable scheduling, and query cardinality. I reviewed committed source with `git show <commit>:<path>` and local-only changes from the `.snapshot` paths recorded in `worktree-manifest.json`. I did not modify product source or product tests.
+
+## Outcome
+
+Five prior correctness findings remain open, and both prior performance findings are fixed. I found one additional concrete performance issue in the durable scheduler. The final main fingerprint added one late performance-parity gap, M10. Startup corruption verification has a separate, unmeasured safety/performance tradeoff recorded below; it is not a continuation of F15.

+
+F01, F03, F04, F05, and F13 are rollout risks. F14 is a real fix in the last committed reconciliation. F15 is fixed by the candidate-selection work in `d98f1d5e38`.
+
+## F01: historical V2 migration cohorts still cannot upgrade
+
+### Evidence
+
+The frozen manifest puts main migrations at 44 through 47 and the V2 sequence at 48 through 58 (`apps/server/src/persistence/Migrations.ts` at frozen HEAD, lines 58-72 and 128-142). The runner executes only IDs above the latest recorded ID (`Migrations.ts:166-184`). It does not use the recorded migration names to reconcile a renamed history.
+
+I verified the manifest-selected migration bodies by Git blob identity, not by filename inference:
+
+| Historical cohort         | Historical manifest   | Current identical bodies |
+| ------------------------- | --------------------- | ------------------------ |
+| `c1791ab2637`             | V2 migrations 044-052 | Current 048-056          |
+| Prior audit `d2f1f511...` | V2 migrations 045-053 | Current 048-056          |
+| `d98f1d5e38`              | V2 migrations 045-055 | Current 048-058          |
+
+The old `c1791ab2637` tree contains an unused `044_ClearAutomaticProjectModelDefaults.ts`, but its manifest imports and records `044_OrchestrationV2`. The cohort comparison and probe use the manifest-selected file.
+
+The audit probe uses the actual current migration functions to create those byte-identical historical schemas under their recorded old IDs, then invokes the actual current migrator against in-memory SQLite. Results:
+
+- Old 052 starts current 053 `ApplicationEventSource`, whose old 049 body already ran. Its unconditional `ALTER TABLE ... ADD COLUMN application_event_version` at `053_ApplicationEventSource.ts:33-47` fails with a duplicate-column error.
+- Old 053 starts current 054 and reaches current 056 `LegacyV1ImportState`, whose old 053 body already created the table. `056_LegacyV1ImportState.ts:9-26` fails because the table already exists.
+- Old 055 starts current 056 and fails at the same preexisting legacy-import table.
+
+All three failures roll the attempted migration batch back to the prior recorded maximum. The probe also confirms that old 055 lacks `auto_pull` and `project_icon_json` because numeric IDs 45 through 47 are treated as already applied.
+
+The skipped work depends on cohort:
+
+- Old 052 skips current 044 through 052, including `ClearAutomaticProjectModelDefaults`, `ProjectionProjectsAutoPull`, `RepairAutomaticSettlementTimestamps`, and `ProjectionProjectIcon`.
+- Old 053 and 055 already applied current 044 under that name, but skip current 045 through 047 and the renumbered V2 steps below their maximum.
+
+Main itself ends at migration 047. A database produced by current main therefore advances into branch migration 048 correctly. Fresh installs also work. This is a branch-history compatibility regression, not main lag.
+
+### Trigger and consequence
+
+Start the frozen build against a database previously opened by any of the reproduced V2 cohorts. Server startup fails before readiness. Making only one DDL statement idempotent would move the collision but would not execute the skipped main data repairs and schema additions.
+
+### Required coverage
+
+Use a manifest-aware bridge keyed by recorded `(migration_id, name)` history, then append idempotent repair migrations for any main work skipped by old numeric maxima. Add table-driven upgrade fixtures for each supported historical manifest and useful partial stopping points. Fresh-schema tests cannot prove upgrade compatibility.
+
+### Overlay
+
+The frozen overlay adds migration 059 with three indexes. The audit probe confirms committed 058 upgrades through live 059 and the indexes exist. Historical cohorts still fail at 053 or 056 before 059 can run, so the finding applies equally to frozen committed 058 and the local 059 overlay.
+
+## F03: full diff still fails after an ordinary second run
+
+### Evidence
+
+For a zero baseline, `CheckpointDiffQuery` finds run ordinal 1 and requires a `root_run` scope whose current `runId` equals that first run (`apps/server/src/checkpointing/CheckpointDiffQuery.ts` at frozen HEAD, lines 157-170). If it cannot find that scope, it returns `CheckpointRefUnavailableError` at lines 173-179.
+
+Production creates a different state:
+
+- `IdAllocator.allocate.checkpointScope` derives the ID only from `threadId` and scope name (`orchestration-v2/IdAllocator.ts:295-300`).
+- Every ordinary root run requests the same name, `root`, while storing the current `runId` in the scope payload (`CheckpointService.ts:184-210`).
+- Projection upsert replaces the prior row for that deterministic scope ID, including its ownership fields.
+
+The real allocator/reducer audit probe allocates and applies two ordinary root scopes. Both allocations return the same ID; after run 2, there is one scope row and its `runId` is run 2. Root independently confirmed the same production ownership shape.
+
+The product test fabricates two different root scope IDs and retains one scope for each run (`checkpointing/CheckpointDiffQuery.test.ts:18-44`). Its happy path therefore cannot be produced by the allocator it is meant to cover.
+
+### Trigger and consequence
+
+Complete two ordinary runs in one Git-backed thread, then request a full diff through turn 2. The shared scope's ordinal-zero baseline ref is still derivable, and the target checkpoint exists, but the query rejects because the shared scope is no longer owned by run 1. Full-thread diff fails from the second completed run onward.
+
+The zero baseline should be resolved from the actual shared root scope, normally the target checkpoint's scope, rather than by joining scope ownership to run ordinal 1. Replace the two-scope fixture with state made by the real allocator/projector.
+
+### Overlay
+
+No frozen overlay file changes `CheckpointDiffQuery`, `IdAllocator`, or `CheckpointService`. The ProjectionStore overlay does not change checkpoint-scope ownership. F03 remains open locally.
+
+## F04: WebSocket force deletion can partially commit
+
+### Evidence
+
+The WebSocket project handler reads active and archived V2 shells, checks `force`, and independently dispatches one `thread.delete` per thread (`apps/server/src/ws.ts` at frozen HEAD, lines 1299-1319). Only after those commits does it call `ProjectService.delete`, omitting `force` (`ws.ts:1320-1323`).
+
+`ProjectDeleteInput` has no force field, and `ProjectService.delete` dispatches a legacy `project.delete` without one (`project/ProjectService.ts:48-51,363-386`). The legacy decider rejects any nonempty project unless `force === true`; with force, it decides thread and project deletion as one sequence (`orchestration/decider.ts:280-313`).
+
+The legacy importer reads `projection_threads` and writes V2 events, but it intentionally leaves the V1 rows in place (`orchestration-v2/LegacyV1ThreadImporter.ts:459-490`). Once a V2 `thread.created` event exists, the importer does not create that thread again.
+
+### Trigger and consequence
+
+Force-delete through WebSocket a project containing imported V1 threads. V2 thread deletions commit first. The legacy project delete sees the still-present V1 threads and rejects because force was dropped. The project and V1 rows remain, the V2 copies are deleted, and later import does not restore them. This is a destructive partial commit, not merely a mismatched error message.
+
+Main's V1 WebSocket path normalizes the original command and sends it intact to one decider transaction (`ws.ts` at main, lines 1263-1296); the decider carries force through the thread/project sequence. The V2 split coordinator regresses that invariant.
+
+### Overlay
+
+The frozen overlay does not contain `ws.ts`, `ProjectService.ts`, the legacy decider, or the importer. F04 is unchanged.
+
+## F05: project lifecycle still diverges across transports
+
+### Evidence
+
+The shared `ProjectMutation` contract carries:
+
+- `createWorkspaceRootIfMissing` on create;
+- `autoPull`, `projectIcon`, `faviconPath`, and `defaultThreadEnvMode` on update;
+- `force` on delete.
+
+See `packages/contracts/src/project.ts` at frozen HEAD, lines 116-145. The WebSocket create and update branches forward these fields (`apps/server/src/ws.ts:1264-1298`) and perform V2 thread validation/deletion for project removal.
+
+The HTTP mutation handler calls `ProjectService` directly and drops all of the fields above except the older title/root/model/scripts set (`apps/server/src/project/http.ts:45-80`). The live CLI delegates to this HTTP endpoint (`cli/project.ts:324-338`). The offline CLI duplicates the same reduced mapping and direct legacy deletion (`cli/project.ts:423-459`).
+
+The last committed reconciliation added `autoPull`, project icon, favicon, and default environment mode to the shared update contract and WebSocket mapping, but did not add them to HTTP or offline CLI. This broadens F05; it is not a separate finding.
+
+### Triggers and consequences
+
+- Delete a V2-only populated project through HTTP. The V1 read model can see no thread, so the legacy project row is deleted while V2 threads remain and reference a deleted project.
+- Force-delete an imported populated project through HTTP, live CLI, or offline CLI. Force is dropped, so the legacy decider rejects.
+- Send a typed HTTP create with `createWorkspaceRootIfMissing: true`. The service receives the default false behavior.
+- Send a typed HTTP update for `autoPull`, project icon, favicon, or default thread environment mode. The request succeeds without applying that field.
+
+The current HTTP tests cover only error translation (`project/http.test.ts:15-51`). The CLI integration covers add, title rename, and empty-project removal (`cli/project.test.ts:116-133`). Neither suite exercises the dropped fields or populated mixed-store deletion.
+
+One lifecycle coordinator should own validation and mutation across V1/V2, with WebSocket, HTTP, live CLI, and offline CLI preserving the same typed input. Tests need imported and V2-only projects, active and archived threads, force false/true, missing-root creation, and every update field.
+
+### Thread lifecycle note
+
+V2 thread mutation commands remain on the WebSocket command path. The V2 HTTP surface reviewed here serves shell, detail, and history reads through `ThreadManagementService`; it does not define a competing HTTP thread-mutation implementation. I found no separate thread archive/unarchive/delete divergence within that intended split. Project deletion is the cross-store exception because it owns thread cleanup.
+
+### Overlay
+
+No project transport or lifecycle source is present in the frozen overlay. F05 remains open locally.
+
+## F13: stale failure still wakes a newer snooze
+
+### Evidence
+
+For a future snooze, V2 defines `wokeOnError` as `thread.status === "failed"` with no time comparison (`orchestration-v2/ThreadSettlementService.ts` at frozen HEAD, lines 108-117). Completion correctly requires `latestRunCompletedAt > snoozedAt` in the next two lines.
+
+Main's V1 policy requires the error session's `updatedAt` to be newer than `snoozedAt` (`orchestration/ThreadSettlementPolicy.ts` at main, lines 98-109). The V2 shell already exposes the latest run completion time needed for an equivalent ordering check.
+
+The audit probe creates a projected failed run completed on August 20, then a snooze beginning September 1 and ending September 10. At September 4, the production V2 policy returns `true`, treating the old failure as an early wake. The frozen overlay's unit test also explicitly expects any failed status to wake a future snooze without a failure timestamp (`ThreadSettlementService.test.ts.snapshot:127-139`).
+
+### Trigger and consequence
+
+Fail a thread, then snooze it into the future. At the next settlement evaluation, the stale failure defeats the newer snooze. If the thread also matches closed-PR or inactivity settlement policy, it can move to settled before the requested wake time.
+
+Require failed-run completion evidence newer than `snoozedAt`. Cover both failure-before-snooze and failure-after-snooze through the projected candidate path.
+
+### Rejected lead
+
+Closed pull requests should continue to settle when the optional day and on-merge settings are off. `pullRequestSettles` accepts `closed` independently and gates only `merged` on `autoSettleOnMerge` (`ThreadSettlementService.ts:80-92`). The frozen overlay preserves this behavior and its test at `ThreadSettlementService.test.ts.snapshot:230-238`. An unconditional early return when both optional settings are off would remove valid closed-PR behavior and is not recommended.
+
+## F14: checkpoint diff hydration is fixed
+
+Commit `8af5734365` changes checkpoint diff to call `getCheckpointContext` (`checkpointing/CheckpointDiffQuery.ts:102-121`). `ProjectionStore.getCheckpointContext` performs three narrow queries for run ID/ordinal/status, scope ID/run/kind/cwd, and checkpoint scope/run/app ordinal/status/ref (`orchestration-v2/ProjectionStore.ts:2957-3002`). It does not read transcript messages, turn items, provider histories, or fork ancestry.
+
+The focused checkpoint diff suite passes 5 tests. This fixes the prior read-cardinality issue. It does not fix F03 because the narrow query faithfully returns the production shared-scope ownership that the zero-baseline logic mishandles.
+
+The frozen ProjectionStore overlay retains the narrow query unchanged.
+
+## F15: startup recovery targeting is fixed
+
+Commit `d98f1d5e38` removes the prior recovery call over every active and archived shell. `ProviderRuntimeRecoveryService` now asks for `getRecoveryThreadIds("runtime")` and full-loads only those candidates (`ProviderRuntimeRecoveryService.ts:482-511`). The candidate SQL selects nonterminal runs, pending runtime requests, nonterminal sessions, provider-owned background work, relevant nonterminal turn items, and pending/running outbox entries (`ProjectionStore.ts:2696-2787`). The focused recovery tests confirm terminal histories are not loaded for runtime reconciliation.
+
+That fixes F15 as previously defined and recommended. It also removes repeated shared-session and fork-history hydration. The frozen overlay does not regress this path.
+
+## Separate startup corruption-verification tradeoff
+
+Startup still blocks command readiness on `projectionMaintenance.verify` (`serverRuntimeStartup.ts:518-553`). Verification calls `getUnreadableThreadIds` (`ProjectionMaintenance.ts:75-119`), which pages through all 16 canonical projection tables, selects each `payload_json`, and schema-decodes every row (`ProjectionStore.ts:2789-2952`). Messages, turn items, provider turns, checkpoints, active threads, archived threads, and terminal history are all included. Paging at 500 bounds peak row memory and each canonical row is decoded once, but total startup work remains O(all retained V2 projection rows).
+
+This is not the old F15 recovery behavior. It is an intentional safety check that detects corrupt canonical rows and propagates unreadability through fork ancestry before accepting commands. I did not benchmark its latency or memory impact, so it is not reported as a defect. Benchmark representative large databases before deciding whether the readiness cost is acceptable. Any optimization must preserve equivalent corruption detection, for example through validated incremental metadata or another complete verification strategy; simply removing or narrowing the scan would weaken recovery safety.
+
+The frozen overlay improves periodic settlement separately by adding `getSettlementCandidates` and narrow `getThread` reads. Migration 059 supplies the relevant indexes. It does not change startup verification.
+
+## PERSIST-N01: the scheduler ignores its due-task index every five seconds
+
+Priority: P2 performance.
+
+### Evidence
+
+`ScheduledTaskService.selectAllRows` selects every column of every scheduled task and orders the complete table by update time (`scheduledTasks/ScheduledTaskService.ts` at frozen HEAD, lines 175-199). `listTasksLenient` decodes every row's schedule, workspace strategy, and model selection (`:207-224`). `runDueTasks` calls that full-list path and only then filters enabled, due, and non-running tasks in memory (`:583-609`). The loop repeats every five seconds (`:665-669`).
+
+Migration 055 already creates `idx_scheduled_tasks_due(enabled, next_run_at)` with a partial predicate for enabled tasks having a next run (`persistence/Migrations/055_ScheduledTasks.ts:32-36`). The polling query has no `WHERE` clause, so it cannot use that index to bound candidates by `next_run_at`.
+
+### Trigger and consequence
+
+Accumulate many disabled tasks or enabled tasks scheduled far in the future. Even when nothing is due, the server reads, allocates, JSON-decodes, and sorts every row every five seconds. Cost is O(all scheduled tasks) per poll instead of O(due tasks), creating steady database and CPU load.
+
+This scheduler is branch-only at the compared main commit, so the issue is not main lag. It is a scaling defect in the added durable scheduling core. Query due rows directly with `enabled = 1`, non-null `next_run_at`, `next_run_at <= now`, and non-running status. Crash recovery can keep its separate one-time running-row query. Add a behavior/cardinality test that seeds many future/disabled rows and proves the poll decodes only due rows.
+
+## M10 late arrival: metadata and provider-control paths still hydrate history
+
+Priority: P2 performance and failure isolation. Status: missing at frozen committed HEAD. The frozen overlay adds useful groundwork but does not address the affected paths.
+
+Late main commit `6365919f2e5bcfb4fa4020b95e19af26ae40979f`, [#9758](https://github.com/pingdotgg/t3code/pull/9758), splits `ProviderCommandReactor` reads into thread shell and thread detail. Main now uses shell reads for session state, compaction guards, post-generation title checks, interrupt and recovery, approval and user-input forwarding, session stop, and runtime-mode propagation (`ProviderCommandReactor.ts` at that commit, lines 528-538, 572-608, 984-995, 1375-1385, 1442-1640, and 1700-1715). It keeps detail reads for the two operations that consume transcript data: title regeneration and turn start (`:1008-1058` and `:1178-1201`). Three changed behavior tests put invalid JSON in an old message and prove approval response, user-input response, and session stop no longer decode that unrelated body (`ProviderCommandReactor.test.ts` at that commit, lines 517-530, 3556-3595, 3597-3640, and 3846-3886).
+
+V2 distributes the same responsibilities across services, so copying the V1 reactor would be the wrong fix. The actual paths are:
+
+| Behavior                          | V2 committed path                                                                                                                                                                                                                                                                                                                                                                                                           | Assessment                                                                                                                                                                                                                          |

+| Initial title generation          | `ThreadTitleRegenerationService.ts:184-228` loads the whole projection to locate one initial message, then dispatches completion at `:169-182` and `:247-253`.                                                                                                                                                                                                                                                              | Missing.

+| Metadata and mode mutations       | `Orchestrator.ts:1389-1425` routes `thread.metadata.update`, `thread.title.regeneration.complete`, and runtime/interaction mode changes through `getThreadProjection`. Their reducers use thread payload fields at `:1694-1721`; workspace and runtime-mode changes also inspect provider sessions to plan detaches at `:1884-1900`. `ThreadLifecycleService.ts:80-87` then reads the full projection again for its result. | Missing transcript isolation, but not every case is app-thread-only. Title completion and interaction mode need only the thread. Workspace changes and runtime mode need a narrow thread-plus-session context. None needs messages. |
+| Approval and user-input responses | `RuntimeRequestService.ts:76-125` loads the full projection to locate one runtime request before calling the live session.                                                                                                                                                                                                                                                                                                  | Missing, but a narrow runtime-request lookup is required. The app-thread-only `getThread` read cannot replace this safely.                                                                                                          |
+| Interrupt and restart             | `ProviderTurnControlService.ts:80-162` loads the full projection to validate one provider thread and turn; restart polls the full projection again at `:211-231`.                                                                                                                                                                                                                                                           | Missing. This needs a narrow provider execution context, not a V1 shell port or an app-thread-only read.                                                                                                                            |
+| Session stop and detach           | `Orchestrator.ts:2003-2053` loads the full projection to validate one provider session. `ProviderSessionManager.ts:1566-1605` loads it again when a multi-thread-capable runtime must interrupt attached active turns.                                                                                                                                                                                                      | Missing transcript isolation.

+| Provider turn start               | `ProviderTurnStartService.ts:91-125` reads runs, nodes, attempts, messages, checkpoint scopes, handoffs, and provider state.                                                                                                                                                                                                                                                                                                | No gap.

+
+The committed generic mutation handler creates a concrete failure boundary. `getThreadProjection` selects every message payload for an unwindowed read (`ProjectionStore.ts:2398-2402`) and schema-decodes all of them (`:2515-2531`). A long thread therefore pays O(retained history) to rename a branch, update a title, complete title regeneration, or change runtime mode. One malformed old message also rejects the metadata command before it can emit its event. This is the same isolation problem that the new main tests cover, expressed through V2's projection tables.
+
+The dirty overlay is not a local-only fix for M10. `ProjectionStore.ts.snapshot:173-175` and `:3003-3019` add `getThread`, which selects and decodes only the app-thread payload. `Orchestrator.ts.snapshot:1389-1430` uses it for `thread.visit`, and `:6944-6975` uses it for the auto-settlement guard. However, `thread.metadata.update`, `thread.title.regeneration.complete`, and mode mutations remain in `dispatchThreadMutation`, whose first operation is still `getThreadProjection` (`Orchestrator.ts.snapshot:1432-1468` and `:6988-6995`). Runtime requests and provider-turn control are unchanged in the frozen overlay.
+
+The smallest V2-shaped fix is command-specific. Route title-only metadata, title completion, and interaction-mode mutations through the overlay's `getThread`. Give workspace metadata and runtime-mode mutations a narrow context containing the app thread plus the provider-session fields their detach logic uses. Initial title generation can use a narrow message lookup plus app-thread metadata. Runtime-request response, session detach, and provider-turn control need narrow queries keyed by their existing IDs. Keep full or purpose-built context reads for explicit title regeneration and turn start. Regression coverage should corrupt an unrelated historical message and prove metadata update, title completion, runtime-request response, interrupt, and session stop remain usable without weakening stale-request, detach, or target-identity checks.

+
+## Frozen overlay review
+
+I inspected the requested files separately from committed evidence:
+
+- `Orchestrator.ts.snapshot` moves visits and auto-settlement guards to the new narrow thread metadata read. It preserves forward-only `lastVisitedAt`, deletion checks, and the settlement snapshot guard.
+- `ProjectionStore.ts.snapshot` adds narrow thread and settlement candidate queries. Its SQL excludes archived, deleted, overridden, pinned, active-run, and pending-request rows before loading candidate background data. The paired SQL/memory parity test passes. F13 remains because failed ordering is policy logic after the query.
+- `ThreadSettlementService.ts.snapshot` consumes the candidate query instead of the full shell snapshot. Closed-PR behavior remains correct.
+- `Migrations.ts.snapshot` and `059_OrchestrationV2ShellIndexes.ts.snapshot` add indexes used by the settlement candidate path. The committed-058 to local-059 upgrade probe passes.
+- `GitManager.ts.snapshot`, `GitVcsDriver.ts.snapshot`, and `GitVcsDriverCore.ts.snapshot` let local-only status skip ahead/behind revision walks. Remote status still computes upstream divergence and PR association. The review/action path still requests full status. I found no lifecycle or settlement correctness regression from this change.
+- `server.ts.snapshot` supplies `ProjectionStoreV2.layer` to the application layer required by the new settlement dependency.
+- The new `getThread` primitive is suitable for M10's title-only, title-completion, and other app-thread-only handlers, but the overlay has not routed them through it. It cannot replace workspace/runtime-mode, provider-session, provider-turn, or runtime-request lookups because those need child records.
+
+The overlay's `ProjectionSettlement.test.ts.snapshot` is substantive behavior coverage. It compares SQL and memory candidates, tests background work parity, corrupt historical payload isolation, and query-plan index use. The live version passed. It does not test failure-before-snooze, and the existing settlement unit test currently encodes the opposite behavior.
+
+## Focused validation
+
+No repository-wide check was run. Unique product coverage was 10 files and 52 tests, all passing:
+
+- checkpoint diff, checkpoint rollback, legacy import;
+- projection recovery and provider runtime recovery;
+- schedule calculation;
+- project HTTP error mapping and CLI empty-project lifecycle;
+- live dirty-overlay settlement policy and SQL/memory projection settlement.
+
+The audit-only probe has exactly 6 passing cases:
+
+| Probe name                                                             | Result                                                                              |
+| ---------------------------------------------------------------------- | ----------------------------------------------------------------------------------- |
+| `upgrades committed-058 state through the live-059 overlay`            | Passed                                                                              |
+| `reproduces the old-052 cohort collision against the current migrator` | Passed; asserted the expected current-053 migration failure and rollback            |
+| `reproduces the old-055 cohort collision and skipped main columns`     | Passed; asserted the expected current-056 migration failure and absent main columns |
+| `reproduces the prior-audit old-053 cohort collision`                  | Passed; asserted the expected current-056 migration failure and rollback            |
+| `reproduces root checkpoint-scope reuse across ordinary runs`          | Passed; one shared scope remained owned by run 2                                    |
+| `reproduces a stale failed run waking a later snooze`                  | Passed; production policy returned `true` for the reproduced stale-failure state    |
+
+Exact totals for consolidation: 10 unique product test files with 52 tests passed, plus 1 audit-only probe file with 6 tests passed. Combined, 11 unique test files and 58 tests passed. Repeated authoring/rerun invocations are not counted as additional coverage.
+
+The exact commands and results are in `persistence-tests.log`. The probe is `persistence-audit-probes.test.ts`. It uses in-memory SQLite and actual implementations. No live T3 userdata was opened.
+
+The earlier copied-test import failure reported by root was caused by unsuffixed audit snapshots entering Vitest discovery. All frozen overlay copies now end in `.snapshot`; none was discovered in these runs. It is not a product regression.
+
+## Limitations
+
+- I did not launch a server, provider, browser, simulator, or live/offline CLI process. The project lifecycle findings are deterministic handler/service/decider traces; integrated disposable transport tests remain necessary with a fix.
+- I did not benchmark startup verification or scheduler polling. Startup verification is recorded only as a safety/performance tradeoff; PERSIST-N01 is based on explicit polling SQL and loop cardinality, not measured latency or memory.
+- M10 is a source-only review of late main commit `6365919f2e5bcfb4fa4020b95e19af26ae40979f` and its direct V2 equivalents. I ran no additional tests for this addendum.
+- Migration probes cover three known complete historical manifests. Other partial stopping points still need a table-driven compatibility matrix.
+- I did not modify existing tests. Current green tests do not contradict F03, F04, F05, or F13 because their fixtures omit the production trigger or encode the faulty behavior.
+- Provider adapter protocol behavior, auth/relay, title retry, PR metadata, WebSocket fallback F16, and the separately reviewed archived-thread scheduler/MCP lead are outside this report.

Cursor settings no longer define `binaryPath` or `apiEndpoint`. Provider instances expose `orchestrationAdapter` instead of `adapter`.\n>\n> <!-- Macroscope's review summary starts here -->\n>\n> <sup><a href=\"https://app.macroscope.com\">Macroscope</a> summarized 8af5734.</sup>\n> <!-- Macroscope's review summary ends here -->\n>\n<!-- Macroscope's pull request summary ends here -->\n\n<!-- CURSOR_SUMMARY -->\n---\n\n> [!NOTE]\n> **Medium Risk**\n> Mobile thread persistence and list/archive/stop behavior change with V2 runtime semantics; removing the thread-transfer report workflow reduces PR visibility into transfer budget regressions.\n> \n> **Overview**\n> This slice of the orchestration V2 rollout **retires the thread-transfer PR comment pipeline** (trusted publisher script, tests, and `workflow_run` workflow) while CI can still emit transfer artifacts; it also **installs `build-essential` in CI** so ACP process-tree fixtures compile instead of soft-skipping.\n> \n> **Mobile** moves onto shared V2 client-runtime pieces: SQLite cache uses `ORCHESTRATION_CACHE_SCHEMA_VERSION` and stored V2 shell/thread snapshots, runtime wiring swaps in bounded thread snapshot loading and history control, and thread detail/review/archive flows read **projections** (`runtime`, `RuntimeRequestId`, checkpoint summaries from `runId`) instead of V1 session/turn shapes. UX additions include **activity inspector**, **queue control**, **relationships banner**, progressive **history controls**, server **visit** watermarking, stricter **archive** rules via `threadCanArchive`, and approval/user-input cards that honor **live vs dead** provider `responseCapability`.\n> \n> Smaller touches: shared **brand mark** module, new **uniwind adaptive color** tokens, desktop env test for user-data dir names, README link to appearance docs, and marketing copy for Cursor harness.\n> \n> <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit 9eeed8c17109be3752d2f8e1643583d1f579ea2d.

+# Orchestrator V2 provider parity and regression audit
+
+## Result
+
+The frozen committed branch still has four provider findings from the 2026-09-02 audit and has four additional concrete provider-parity defects exposed by changes that landed on main since that audit. I found no current-main-only provider change among the final eight unmerged commits and no committed registration, discovery, or auth regression across the seven built-in drivers.
+
+The dropped range-diff patch for Codex availability was absorbed by the refactor. It is not a regression: `CodexProvider.ts:489-525` still produces the unchecked pending snapshot with `installed: false`, and `CodexDriver.ts:192-204` still uses that builder as the managed driver's `initialSnapshot`.
+
+Audit basis:
+
+- Frozen branch: `8af5734365f7c45bc08b57066dbae42f9f7d4235`

+| F06 |       P1 | Persists in committed HEAD | OpenCode V2 treats descendant enumeration, descendant abort, and the whole 15-second descendant traversal as best effort (`OpenCodeAdapterV2.ts:3121-3150`). Only the root abort can reach `ProviderAdapterInterruptError`. An explicit Stop can therefore acknowledge success while a child session continues. Current main preserves the first relevant descendant error instead of discarding it (`OpenCodeAdapter.ts:756-823`).                                             |
+| F07 |       P1 | Persists in committed HEAD | An external OpenCode server is accepted at `OpenCodeAdapterV2.ts:893-905`, but session teardown only aborts the local SSE controller at `2542-2548`. The now-bounded and logged manager scope close (`ProviderSessionManager.ts:651-705`) prevents release itself from hanging; it does not abort the root or child OpenCode sessions. Current main calls bounded root and descendant aborts during teardown (`OpenCodeAdapter.ts:825-837`).                                    |
+| F08 |       P1 | Persists in committed HEAD | Cursor metadata generation still launches the SDK in unrestricted `agent` mode at the real project cwd with its sandbox disabled (`CursorTextGeneration.ts:75-124`). The timeout bounds duration, not filesystem effects. Current main uses Cursor ACP and requests `ask` mode before prompting (`CursorTextGeneration.ts:85-105`).                                                                                                                                             |
+| F11 |       P2 | Persists in committed HEAD | Claude `Read` remains a generic `dynamic_tool`: the classifier only accepts the tool name and maps `read` without inspecting the path (`ClaudeAdapterV2.ts:1401-1449, 3614-3626`). Web and mobile then reduce dynamic tool data to input/output (`apps/web/src/session-logic.ts:631-637`; `apps/mobile/src/lib/threadActivity.ts:534-539`), so the shared image-preview path never receives `viewedImagePath`. Coordinate the client presentation portion with the root review. |
+
+F12 and F16 are owned by the root audit and are not duplicated here.
+
+## New concrete findings
+
+### PROV-OPENCODE-01: P1, a clean SSE EOF silently disables all later provider events
+
+`OpenCodeAdapterV2.ts:2542-2575` creates one `event.subscribe` stream. Its terminal handler returns without changing session state when `Exit.isSuccess(exit)` at line 2562. The public provider runtime continues exposing a separate never-ending queue stream at `2710-2716`, so the session manager does not observe that the native subscription fiber ended.
+
+Trigger: the SDK async iterable ends cleanly without the local abort signal being set. This includes a transport that reports disconnect as EOF instead of throwing.
+
+Consequence: the provider session remains apparently ready, but subsequent status, text, tool, approval, and completion events are no longer ingested. An active turn or request can remain stuck, and later activity on the same session is invisible.
+
+Current main addressed this in [#9653](https://github.com/pingdotgg/t3code/pull/9653): `OpenCodeAdapter.ts:2713-2757` records SSE errors and emits an unexpected-exit failure even when the iterable ends successfully, enabling the stopped/reconnect path. This is a missing port, not an intentional V2 difference.
+
+I left this finding source-backed. The existing mocked adapter lifecycle does not expose a receipt when the private subscription fiber completes. A passing absence assertion after closing the iterable would depend on scheduler timing, so it would not be a meaningful regression probe.
+
+### PROV-OPENCODE-02: P1, approval and question replies can hang the durable effect worker indefinitely
+
+`OpenCodeAdapterV2.ts:3162-3212` calls `question.reply` and `permission.reply` without passing an SDK abort signal and without a timeout. The orchestrator has already persisted the request as resolved before enqueueing this external effect (`Orchestrator.ts:5068-5075, 5222-5237`), and `RuntimeRequestService.ts:91-125` then waits directly on the adapter call.
+
+Trigger: an OpenCode server accepts the reply connection but never resolves it.
+
+Consequence: the user cannot submit another answer because the durable request is already resolved, while the provider may never receive the response. The call also pins one effect worker and leaves its outbox row running. `EffectWorker.ts:216-238` and `RuntimeRequestService.ts:112-138` only translate errors; neither adds cancellation or a deadline. The worker races execution only against the outbox's explicit cancellation signal (`EffectWorker.ts:485-502`). `EffectOutbox.ts:278-303` claims pending rows only and blocks later non-title effects in the same thread while this row remains running. Lease expiry does not start an automatic duplicate attempt. One hung reply therefore blocks that thread's effect lane until explicit cancellation or process restart; four distinct hung replies can occupy the default four-worker pool.
+
+Current main addressed both reply types in [#9653](https://github.com/pingdotgg/t3code/pull/9653): it passes the SDK signal, applies a 10-second timeout, and only then resolves the local pending request and emits its terminal event (`OpenCodeAdapter.ts:3611-3715`). This is a missing port.
+
+### PROV-CLAUDE-01: P1, new Claude dead-turn terminal reasons are reported as successful completion
+
+The branch already depends on Claude Agent SDK `0.3.260`, but V2's result classifier predates that SDK's structured dead-turn results. `ClaudeAdapterV2.ts:1991-2025` returns `completed` for every `subtype: "success"`, `is_error: false` result, regardless of `terminal_reason`; `providerFailureFromResult` likewise returns no failure at `2045-2065`. The result handler commits those values at `4769-4788`.
+
+Trigger: Claude exhausts retries or otherwise ends with a structured failure such as `terminal_reason: "api_error"`, `"blocking_limit"`, `"rapid_refill_breaker"`, `"prompt_too_long"`, `"image_error"`, `"model_error"`, `"malformed_tool_use_exhausted"`, `"budget_exhausted"`, `"structured_output_retry_exhausted"`, `"tool_deferred_unavailable"`, or `"turn_setup_failed"`, while the SDK reports a success subtype and no ordinary error.
+
+Consequence: a turn that produced no successful answer is projected as completed and has no provider failure for the UI to explain.
+
+Current main added the structured classification and user-facing messages in [#9135](https://github.com/pingdotgg/t3code/pull/9135) (`ClaudeAdapter.ts:438-478, 1510-1548`), including a regression test for the observed `success` / `is_error: false` / `terminal_reason: "api_error"` shape and exhaustive tests for the dead-turn set. This is a missing port.
+
+`provider-adapter-regression-probes.test.ts` confirms the behavior through the actual V2 adapter. It starts a mocked Claude query session, sends the observed `api_error` result shape through the adapter's message stream, and receives `turn.terminal` with `status: "completed"` and `failure: null`. The probe passed as a reproduction in 25 ms.
+
+### PROV-OPENCODE-03: P2, OpenCode per-turn token telemetry is always unavailable
+
+`OpenCodeAdapterV2.ts:1029-1051` emits terminal provider-turn updates without `turnTokenUsage`. Its part switch at `2310-2340` handles text, reasoning, and tools, but ignores `step-finish`, the OpenCode event carrying token counts. `ProviderEventIngestor.ts:88-114` therefore emits `usageStatus: "unavailable"` for every OpenCode turn.
+
+Consequence: V2 OpenCode terminal provider-turn telemetry and its analytics properties cannot report per-turn input, cache, output, or reasoning token counts. This does not prove increased spend and does not establish that a separate transcript-backed usage dashboard is missing data.
+
+Current main added ownership-aware `step-finish` accumulation and complete/partial/unavailable terminal usage in [#9132](https://github.com/pingdotgg/t3code/pull/9132) (`OpenCodeAdapter.ts:403-439, 2409-2429`). Codex and Claude V2 already populate the same provider-turn field. This is a missing port.

+
+## Main-since-prior and final-eight review
+
+The main changes that materially affect this domain since the prior audit are the OpenCode transport/request fixes in [#9653](https://github.com/pingdotgg/t3code/pull/9653), OpenCode token accumulation in [#9132](https://github.com/pingdotgg/t3code/pull/9132), Claude terminal classification in [#9135](https://github.com/pingdotgg/t3code/pull/9135), Claude attachment ordering in [#9122](https://github.com/pingdotgg/t3code/pull/9122), provider image-embedding instructions in [#9597](https://github.com/pingdotgg/t3code/pull/9597), OpenCode access rules in [#9282](https://github.com/pingdotgg/t3code/pull/9282), OpenCode workspace skills in [#9585](https://github.com/pingdotgg/t3code/pull/9585), and Codex async questions in [#9512](https://github.com/pingdotgg/t3code/pull/9512). Except for the four new findings above, the inspected V2 equivalents of those provider fixes are present.
+
+Mobile's cwd-specific provider catalog refresh from [#9180](https://github.com/pingdotgg/t3code/pull/9180) is present at `use-composer-command-menu.ts:188-244`; the prior broad V02 “outside web” validation gap should not be carried forward. I did not establish a narrower execution-only stale-catalog failure. Project auto-pull is also retained through `VcsStatusBroadcaster` policy and startup `autoPullProjects`; no missing provider launch hook was found.
+
+The final eight commits between branch HEAD and frozen main are [#9740](https://github.com/pingdotgg/t3code/pull/9740), [#9744](https://github.com/pingdotgg/t3code/pull/9744), [#9627](https://github.com/pingdotgg/t3code/pull/9627), [#9748](https://github.com/pingdotgg/t3code/pull/9748), [#9747](https://github.com/pingdotgg/t3code/pull/9747), [#9749](https://github.com/pingdotgg/t3code/pull/9749), [#9743](https://github.com/pingdotgg/t3code/pull/9743), and [#9739](https://github.com/pingdotgg/t3code/pull/9739). None changes a provider registry, adapter, provider text-generation helper, or provider contract in this bounded scope. The branch's lag behind those commits is not itself a provider regression.
+
+## Dirty overlay
+
+The only provider-material frozen overlay change is local-only: `CodexAdapterV2` adds `optOutNotificationMethods: ["turn/diff/updated"]`, with the matching fixture/test update. It asks Codex app-server not to send a notification that T3 already presents through its own diff flow. I found no new regression in that local change. The focused Codex test passed against the live overlay.
+
+The frozen `Orchestrator.ts.snapshot` has no content difference from committed HEAD for this domain. Other recorded session-turn-control/fixture changes are interface or settlement work outside a concrete provider regression. No product source or existing test was modified by this audit.
+
+## Tests and limitations
+
+Focused live-worktree run: 9 files, 215 tests passed in 2.17 seconds. The exact target and result are in `providers-tests.log`. The selection covered all seven V2 adapter suites plus provider auth and instance-registry live tests.
+
+Audit-only behavior probe: 1 file, 1 test passed in 632 ms total, with 25 ms spent in the test. The exact command and result are in `provider-adapter-regression-probes.log`. It imported and exercised the real `makeClaudeAdapterV2` implementation with an in-process query runner. The probe stays in this audit directory and does not alter product tests.
+
+These are mock/in-process suites. The new probe covers the observed Claude `api_error` result shape but not every new terminal reason. No test here exercises graceful OpenCode SSE EOF, a never-resolving OpenCode reply promise, OpenCode `step-finish` token accumulation, real Cursor metadata filesystem behavior, or Claude Read image presentation. Their passing result therefore does not contradict the remaining source-path findings.
+
+No provider or server was launched, no browser/simulator was used, no live T3 userdata was touched, no network was used, and no repo-wide check ran. The copied audit tests now use `.snapshot` suffixes; the earlier Vitest substring import failure caused by an unsuffixed frozen copy was an audit-artifact issue, not a product regression.

++## Background work and navigation
++
++The settlement worker reads active, unpinned threads without explicit settlement overrides from
++`ProjectionStore.getSettlementCandidates`. It reads the latest run and user-message timestamps,
++rejects active runs and pending requests, and checks background work using the same derivation as
++the shell. It does not load archived histories, fork ancestry, transcript counts, or provider
++sessions. The orchestrator still validates the current thread before applying settlement.
++
++Read receipts use `ProjectionStore.getThread` to load only canonical thread metadata. A visit
++advances `lastVisitedAt` monotonically without changing `updatedAt` or decoding history. Shell
++queries use a covering thread/run index for item counts and a partial index for nonterminal
++background items, including idle items. Latest user-message reads use an index ordered by update
++time.
++
++Command palette results keep live VCS and linked pull-request queries leased to the visible
++viewport, including a small overscan region. Cached badges remain available while leases are
++released. Local Git status reads skip divergence calculations; callers that need ahead/behind
++counts keep the full status path. Cached fetch failures share the existing backoff and log only
++the actual failed attempt. Unchanged desktop environment bootstrap reads retain their array
++identity so polling does not invalidate subscribers.
++
++Relay awareness queues one pending publication per thread and retains a follow-up when the thread
++changes during a send. Transcript deltas and tool output do not enqueue awareness work. Run,
++request, and relevant thread metadata events do. Configuration is checked before shell reads, and
++connection changes invalidate published identities so relinking can publish unchanged state.
++Failed publications retry the latest state up to five times with exponential delays. A new
++relevant event resets the budget; successful publication, disabling, or unlinking cancels retries.
++After the budget is exhausted, publication waits for another relevant event instead of generating
++continuous traffic during an outage.
++
++Focused coverage: `ProjectionSettlement.test.ts`, `ThreadSettlementService.test.ts`,
++`runtimeLayer.test.ts`, `AgentAwarenessRelay.test.ts`, `GitVcsDriverCore.test.ts`,
++`ThreadStatusIndicators.subscriptions.test.tsx`, and `desktopLocal.test.ts`.

+# Mobile development lifecycle
+
+Ordinary component changes use Metro Fast Refresh. The connection runtime uses
+a stable development-only atom runtime whose writable layer atom receives the
+newly evaluated Effect layer. Its module accepts the update only after installing
+that layer. Existing subscribers observe the new context, and Effect releases the
+previous runtime scope without restarting React Navigation. Production uses an
+ordinary `Atom.runtime` without this hot-update boundary.
+
+Replacing the atom registry itself disposes its old nodes; replacing the managed
+runtime starts its asynchronous disposal. These modules use normal Metro update
+propagation. The app does not call `DevSettings.reload` during their replacement.
+React can still reset state when its normal Fast Refresh rules require it.
+
+Do not reset the shared registry to clean up a connection-runtime edit: registry
+reset removes listeners from unedited mounted consumers. Do not self-accept a
+runtime module while leaving importers attached to its old implementation. A
+hot-update boundary must install fresh behavior through the existing reactive
+dependencies. These boundaries do not make every module-level atom family in the
+app hot-swappable; new runtime singletons still need explicit ownership. Editing
+the registry or managed runtime can still rebuild a much larger dependency graph
+than an ordinary component or connection-runtime edit.
+
+Environment supervisor scopes are children of the connection registry scope.
+The registry's per-environment map supports targeted shutdown, but it cannot be
+the sole owner: a supervisor created after that map's finalizer has run must
+still inherit the closed parent scope. Otherwise interrupted startup or runtime
+replacement can leave a session and WebSocket alive outside the current registry.
+
+The compact Home list owns its minute-based presentation clock in a focus effect.
+Blur clears the interval without a render-driving focus subscription; focus
+refreshes the clock immediately. Other prop or state changes can still render
+the hidden list. Exact snooze-expiry timers remain active, and the visible iPad
+sidebar keeps its own minute updates.
+
+Connection and runtime projections are shared per environment. Thread selection
+consumers should read those atoms instead of repeatedly parsing the same socket
+URL or constructing new connection objects during each render.
+
+The Uniwind dependency patch still recompiles CSS on Metro updates so newly used
+classes are discovered. It fingerprints the generated native stylesheet and
+theme list, then skips development-only global invalidation when that output is
+unchanged. A changed stylesheet or theme list still resets the style caches and
+notifies subscribers. The digest is committed only after initialization succeeds.
+Web and production retain their existing initialization behavior.
+
+After installing or changing the Uniwind patch, restart Metro once with
+`vp run dev:client:reset` from `apps/mobile`. pnpm gives patched packages new
+filesystem paths, and cached transforms can otherwise retain references to the
+previous package. Ordinary development starts should retain the transform cache.
+
+The expo-notifications patch protects `NotificationCenterManager`'s delegate and pending-response
+arrays with a lock. React runtimes can register and remove delegates concurrently during reloads
+or native scene startup. Delivery takes a snapshot under the lock and invokes delegates after
+releasing it, allowing callbacks to register other delegates. Pending-response replay removes
+only the responses it saw so a response arriving during a callback remains available.
+
+Changes to this native patch require a fresh dependency install, CocoaPods refresh, and an iOS
+rebuild. `vp test run apps/mobile/scripts/notification-center-manager.test.ts` compiles the
+installed dependency with a small native harness on macOS and runs concurrent registration and
+delivery checks under ThreadSanitizer without launching a simulator.

+# Performance regression checks
+
+The v2 transport has a focused regression command:
+
+```bash
+vp run test:perf:v2-wire
+```
+
+It exercises the real v2 projection and client reducers. This matters because the older
+built-app benchmark fixtures seed v1 orchestration events; running those fixtures against a v2
+client can produce reassuring timings while missing the active transport path.
+
+The v2 checks pin these invariants:
+
+- Client cold opens use a recent timeline window capped at 75 rows and about 1 MiB of encoded
+  timeline data.
+- The bounded snapshot does not retain the full duplicate conversation-message table.
+- Older activity is fetched in bounded HTTP pages and merged without disturbing the live scroll
+  window.
+- Resume catch-up replays at most 128 thread events and 1 MiB of projected event JSON before
+  replacing stale state with a current snapshot.
+- Oversized dynamic-tool results and detail strings are reduced only at the wire boundary; the
+  persisted event remains complete.
+- The initial shell contains active navigation rows only. Archived rows use the dedicated archive
+  query, and transcript message bodies stay in thread detail regardless of message size.
+- Shell resume sends deltas plus compact repository-enrichment metadata, not another full project
+  and thread snapshot.
+- Known idle sends and interrupts do not fetch a full thread projection before dispatch.
+
+When changing projection schemas, paging, shell synchronization, or thread state, run this command
+alongside the focused package typechecks and a real-client pass on every affected surface. Payload
+budgets belong in these tests rather than logs or one-off recordings so regressions fail locally.
+
+## Event store and startup
+
+Sequence cursors must seek an index rather than scan retained history. The application sequence
+index contains project events and v2 thread events; the per-thread sequence index contains only v2
+thread events. Legacy-only and unknown threads must return zero without scanning other threads.
+Catch-up queries keep sequence ranges and optional thread or command predicates indexable.
+
+Startup selects recovery candidates from current projection state before reading full thread
+projections. Candidate selection includes queued runs, pending runtime requests, live provider
+sessions, background work, and unfinished delegated deliveries. Archived threads still participate
+where recovery requires them. Completed thread history is not loaded merely to discover that no
+work remains.
+
+Projection verification decodes canonical rows in bounded pages, including shared provider records
+and fork ancestry. Rebuild replays event pages through a fixed sequence within its transaction;
+it must not collect the entire event log before projecting it.
+
+The focused regression coverage lives in `OrchestrationEventStore.sequence.test.ts`,
+`ProjectionRecovery.test.ts`, and the provider runtime recovery tests under `apps/server/src`.
+
+## Background work and navigation
+
+The settlement worker reads active, unpinned threads without explicit settlement overrides from
+`ProjectionStore.getSettlementCandidates`. It reads the latest run and user-message timestamps,
+rejects active runs and pending requests, and checks background work using the same derivation as
+the shell. It does not load archived histories, fork ancestry, transcript counts, or provider
+sessions. The orchestrator still validates the current thread before applying settlement.
+
+Read receipts use `ProjectionStore.getThread` to load only canonical thread metadata. A visit
+advances `lastVisitedAt` monotonically without changing `updatedAt` or decoding history. Shell
+queries use a covering thread/run index for item counts and a partial index for nonterminal
+background items, including idle items. Latest user-message reads use an index ordered by update
+time.
+
+Command palette results keep live VCS and linked pull-request queries leased to the visible
+viewport, including a small overscan region. Cached badges remain available while leases are
+released. Local Git status reads skip divergence calculations; callers that need ahead/behind
+counts keep the full status path. Cached fetch failures share the existing backoff and log only
+the actual failed attempt. Unchanged desktop environment bootstrap reads retain their array
+identity so polling does not invalidate subscribers.
+
+Relay awareness queues one pending publication per thread and retains a follow-up when the thread
+changes during a send. Transcript deltas and tool output do not enqueue awareness work. Run,
+request, and relevant thread metadata events do. Configuration is checked before shell reads, and
+connection changes invalidate published identities so relinking can publish unchanged state.
+Failed publications retry the latest state up to five times with exponential delays. A new
+relevant event resets the budget; successful publication, disabling, or unlinking cancels retries.
+After the budget is exhausted, publication waits for another relevant event instead of generating
+continuous traffic during an outage.
+
+Focused coverage: `ProjectionSettlement.test.ts`, `ThreadSettlementService.test.ts`,
+`runtimeLayer.test.ts`, `AgentAwarenessRelay.test.ts`, `GitVcsDriverCore.test.ts`,
+`ThreadStatusIndicators.subscriptions.test.tsx`, and `desktopLocal.test.ts`.

+# Provider architecture
+
+> For maintainers. Using T3 Code? See [docs/user](../user/).
+
+A provider is the agent runtime that does the actual work. T3 Code supports several, and the
+orchestration layer does not know which one is behind a thread.
+
+## Built-in drivers
+
+[`builtInDrivers.ts`][drivers] exports `BUILT_IN_DRIVERS` with six entries:
+
+| Driver kind   | Driver source                                 |
+| ------------- | --------------------------------------------- |
+| `codex`       | [`Drivers/CodexDriver.ts`][codex]             |
+| `claudeAgent` | [`Drivers/ClaudeDriver.ts`][claude]           |
+| `cursor`      | [`Drivers/CursorDriver.ts`][cursor]           |
+| `grok`        | [`Drivers/GrokDriver.ts`][grok]               |
+| `opencode`    | [`Drivers/OpenCodeDriver.ts`][opencode]       |
+| `antigravity` | [`Drivers/AntigravityDriver.ts`][antigravity] |
+
+Each driver declares its `driverKind`, a `configSchema`, and a `create` function that builds an
+adapter in a child scope. V2 adapter implementations live in
+`apps/server/src/orchestration-v2/Adapters/` and conform to
+[`ProviderAdapter.ts`](../../apps/server/src/orchestration-v2/ProviderAdapter.ts). Read the driver plus its adapter to see how a specific agent's
+transport, config, and event shapes are mapped.
+
+## Runtime context
+
+Every adapter uses `apps/server/src/provider/RuntimeInstructions.ts` to identify T3 Code and
+the harness, and describe Markdown image/video embeds. Codex includes it in developer
+instructions; Claude appends it to its system preset; OpenCode sends it in each prompt's
+`system` field. Grok and Antigravity append a separate text block to ACP prompts,
+which have no system-message field. Cursor supplies context through its SDK prompt. This does not change the stored user message.
+
+Per-turn context includes the current model when known. Codex includes reasoning effort;
+Grok includes it when explicitly selected for the turn. Claude's session-level context omits model and effort because they can
+change during a session. OpenCode variants are not assumed to be reasoning-effort levels.
+
+## Codex async questions
+
+Codex 0.153 exposes `request_user_input_async` through `item/started` and `item/completed`
+notifications. The item has `type: "agentMessage"`, `delivery: "async"`, and a `questions` array.
+Each question has a `title` and an optional `options` array of strings. The tool returns `{"accepted":true}`
+without waiting. This is separate from the `item/tool/requestUserInput` server request.
+See the [Codex tool handler](https://github.com/openai/codex/blob/d979df154cf60e13eafb5453e75b6d84f21c67bf/codex-rs/core/src/tools/handlers/request_user_input_async.rs).
+
+The Codex adapter persists completed question items as `user_input_request` turn items and
+runtime requests with `responseCapability: { type: "message" }`. Their execution nodes do not
+block the run. Web, desktop, and mobile use their normal question panels. The request stays
+pending after the turn finishes, the provider exits, or the server restarts.
+
+`runtime-request.respond` reads the persisted request and question item, validates required
+answers, and commits the resolution and a user message in one transaction. Repeating the same
+command returns its receipt without posting the answer twice. The normal message path starts or
+resumes a run, queues behind active work, or steers an active turn when its adapter supports it.
+Blocking questions retain the provider's live response path.
+
+## Provider diagnostics
+
+Native event logs retain protocol lifecycle events, responses, and failures. Token deltas and
+duplicate raw frames are filtered before adapters copy or redact their payloads. The filter accepts
+both legacy native events and the decoded protocol envelopes used by v2. Decode failures remain
+visible through their diagnostic frames.
+
+Log payloads have a 64 KiB encoded budget. Large or deeply nested payloads become structural
+summaries that retain routing identifiers, methods, status, and error fields. Traversal is bounded
+before redaction and serialization, so a large response cannot create several full copies just to
+write a diagnostic record. These limits apply to logging; provider event handling is unchanged.
+
+Codex thread resume requests exclude historical turns when only the thread identity and update time
+are needed. The adapter decodes those metadata fields without loading a duplicate transcript.
+Its initialization capabilities opt out of `turn/diff/updated`: T3 derives diffs from checkpoints
+and does not consume the provider's cumulative diff notifications. The logger also filters those
+notifications before traversal when an older provider still sends them.
+
+## Registry and routing
+
+Two registries separate configuration from live processes:
+
+- [`ProviderInstanceRegistry`][instances] keys configured instances by `ProviderInstanceId`. Creating
+  one looks up the driver by `driverKind`, decodes `entry.config` with that driver's schema, opens a
+  child scope, and calls `driver.create`.
+- [`ProviderAdapterRegistry`][registry] resolves an instance ID to its live adapter via
+  `getByInstance`.
+
+[`ProviderService`][service] sits on top. It combines the adapter registry with the provider session
+directory to route session and turn operations for a thread, so callers name a thread, not an agent.
+
+`ProviderService.sendTurn` expands [assistant citations](./assistant-citations.md) into quoted
+reference data before dispatching to any adapter. Bound user comments remain distinct from the quoted
+assistant text. Persisted messages keep their serialized links.
+
+Adding a driver means writing the driver plus adapter and adding it to `BUILT_IN_DRIVERS`. No
+orchestration, contract, or client change is required for the common case.
+
+### Grok health check
+
+`checkGrokProviderStatus` never opens an ACP session. It runs `grok --version`, then `grok models`
+for login state and model slugs, then a single ACP `initialize` and reads models from
+`_meta.modelState`. `authenticate` and `session/new` are skipped on purpose: `authenticate` can open
+a browser login and `session/new` boots every configured MCP server, both of which made background
+probes hang or surprise the user. A failed `initialize` degrades to `warning` with the CLI's model
+list instead of persisting `error` over a working install. The built-in `grok-build` slug is the
+CLI's product name, not an ACP model id. `applyGrokAcpModelSelection` treats it as "keep the
+session's current model" and never sends it in `session/set_model`.
+
+## Antigravity ownership and protocol
+
+[`AntigravityDriver`][antigravity] uses Google's official ACP executable. The instance config
+selects the ACP auth method: `oauth-personal` (default), `oauth-business`, `gemini-api-key`, or
+`agent-platform`. The two OAuth methods share the loopback sign-in flow below. The API key
+methods pass the configured key to the agent as `GEMINI_API_KEY` or `GOOGLE_API_KEY` and never
+open a browser. A GCP project and location are written to the profile's `settings.json` on each
+launch. The driver never reuses CLI credentials or ambient `GOOGLE_*` variables and never falls
+back to another method. Antigravity is disabled by default and supports multiple provider
+instances. The open driver and instance identifiers require no database migration.
+
+### Runtime installation
+
+[`AntigravityInstallation`][antigravity-installation] belongs to the environment, outside
+WebSocket and provider-instance scopes. Instances share an explicit download operation and the
+completed runtime. Client disconnects and instance rebuilds do not cancel installation.
+
+The fixed [release table][antigravity-release] contains official Google URLs, SHA-256 hashes,
+archive sizes, and the exact executable pair for each published host. Downloads stream to disk.
+Lazy `yauzl` entry streams extract only that pair, with member names, types, duplicates, and
+sizes checked. Validation runs ACP `initialize` in a temporary profile without authentication
+or a session. Progress updates are bounded, not sent for every network chunk.
+
+Complete releases live in immutable version directories under the T3 home
+`tools/antigravity-acp/<platform>-<arch>/versions`. An atomic `active.json` change selects the
+release for new processes. Each process holds a version lease until it exits. Updates do not
+replace running executables. Removal refuses active leases or explicit binary paths that still
+reference the managed files. Failure or cancellation removes owned partial files, not the
+previous release or account data.
+
+Resolution order is explicit `binaryPath`, active managed release, then the instance's `PATH`.
+An invalid explicit path fails without fallback. Manual installations are never changed by the
+installer. Every launch pins `ANTIGRAVITY_HARNESS_PATH` to the selected executable's sibling.
+
+### Google profiles and sign-in
+
+Each instance owns a stable profile at
+`<stateDir>/providers/antigravity/<sha256(instanceId)>`.
+[`antigravityAuthSupport.ts`][antigravity-auth-support] sets `GEMINI_HOME` to this directory and
+`AGY_ACP_FORCE_FILE_STORAGE=1` after merging instance environment variables. File storage avoids
+the official macOS keychain entry being shared across instances. Profile directories use mode
+`0700` on POSIX. This is file storage, not an encrypted keychain. Windows uses the host profile's
+filesystem permissions.
+
+The launch environment removes API-key and cloud-billing variables, disables inherited
+environment extension, sets `PYTHONUNBUFFERED=1`, and controls `BROWSER`. A tested Node or
+Electron-as-Node helper prevents the official agent from opening a browser on the environment.
+The same launch factory serves setup, health checks, chat, and text generation.
+
+The official agent prints a non-JSON OAuth line on stderr in version 1.1.1. Earlier versions
+print it on stdout. T3 accepts the exact native prefix on either stream and its browser-helper
+marker on stderr. Fragmented lines are joined and bounded. Other malformed protocol output
+remains fatal. Authorization URLs are validated before use. Other stderr is discarded because
+it can contain OAuth data. Normal work rejects an interactive login request with a
+sign-in-required error instead of waiting for consent. A rejected stderr callback fails pending
+ACP requests and closes the owned process.
+
+[`AntigravityAuth`][antigravity-auth] owns each sign-in process and deadline in the instance
+scope. Only the initiating T3 auth session receives its URL and flow ID or can complete or
+cancel it. Other clients receive busy state without those values. Subscriptions follow
+controller replacement when settings rebuild an instance.
+
+For remote completion, the client sends the full return URL through the typed setup RPC.
+The server validates the pending loopback origin, port, root path, and single matching state
+before forwarding once to the owned listener. It does not probe the listener or follow
+redirects. Google's process owns PKCE, token exchange, refresh, and storage. Callback HTTP
+success is not authentication success. The controller waits for authenticated session setup
+and catalog discovery. Cancellation closes the process instead of sending a synthetic denial.
+
+Auth RPCs `provider.auth.start`, `complete`, `cancel`, `logout`, and `subscribe` require
+`orchestration:operate`. Install `start`, `cancel`, and `remove` use that scope too.
+`provider.install.subscribe` and public provider snapshots require `orchestration:read`.
+[`providerSetup.ts`][provider-setup] defines the operation IDs, states, and safe errors.
+
+Sign-out closes process admission for the instance, stops provider bindings through
+[`ProviderAuthService`][provider-auth-service], then stops owned startup and helper processes.
+A fresh official process calls `initialize` and native `logout` without authenticating.
+Only then does the provider clear auth, models, commands, skills, and workspace metadata.
+Thread history and native session files remain. Settings sign-out and a text-only `/logout`
+use this same path. The command is handled before model prompting or title generation.
+Disabling an instance closes its processes but keeps credentials. Account replacement is
+explicit sign-out followed by sign-in.
+
+### Sessions, models, and client capabilities
+
+[`AntigravityAdapter`][antigravity-adapter] owns one ACP process per active thread. It uses
+native `session/resume` without transcript replay and reapplies the persisted model and
+permission mode after new or resumed setup. An unavailable explicit model fails instead of
+accepting the native default. Steering cancels the previous prompt, waits for its result and
+event drain, then sends the replacement. Native background commands use T3's existing
+background-task state.
+
+The permission mapping is `approval-required` and `auto` to `default`, `auto-accept-edits` to
+`auto_edit`, and `full-access` to `yolo`. Native requests still need replies in `yolo`.
+`interaction_` requests are user questions, not approvals. T3 keeps opaque option IDs in
+`UserInputQuestion.options[].value` and sets `allowCustomAnswer=false`. Both clients preserve
+these values. Ordinary approval replies use only offered option IDs, including `allow_always`
+only when present. Existing providers keep their prior behavior when the optional fields are
+absent.
+
+`showInteractionModeToggle=false` keeps native `/plan` separate from T3 Plan mode.
+`supportsConversationRollback=false` hides unsupported client actions and makes checkpoint
+revert fail before filesystem changes. Checkpoint capture and diffs remain supported.
+
+Automatic status refreshes, reconnects, and workspace checks do not open catalog sessions.
+Health probes use `initialize` only. Disabled instances do not run background probes.
+An explicit `serverRefreshProviders` request with `refreshModels: true` calls the driver's
+optional `refreshModels` operation. Antigravity opens a short-lived catalog session under the
+instance's process admission guard, uses saved credentials, publishes models and commands,
+then closes the process. An interactive login request fails with sign-in required. Web's
+**Refresh provider status** and mobile's **Refresh models** actions request this operation.
+Account access starts unknown and becomes authenticated after successful session setup,
+including an explicit model refresh.
+The [provider snapshot][antigravity-provider] takes models and commands from setup and native
+updates. It preserves returned Gemini model IDs, labels, order, and thinking-level choices.
+ACP `config_option_update` notifications and `session/set_config_option` responses replace
+the instance's model catalog. Child session notifications do not change the root catalog.
+The registry treats a successful empty catalog as authoritative and clears cached metadata
+after sign-out. It must not retain a previous account's models. Cached models do not prove
+current access. The auth response does not supply an email, plan tier, or reliable quota.
+
+Some upstream failures arrive as assistant text followed by `end_turn`. Preserve that message
+without treating model-written text as a structured error or successful task completion.
+
+### Text generation
+
+[`AntigravityTextGeneration`][antigravity-text] implements titles, branch names, commit text,
+and PR text through the same instance and Google sign-in. Each helper uses a temporary empty
+workspace, no injected MCP servers, native `default` mode, and explicit denial of tools and
+questions. Output is bounded, parsed against the existing schemas, and sanitized. Cancellation,
+timeout, and sign-out close the process. Cleanup removes only that helper's verified temporary
+native session files.
+
+The official agent has no verified hard no-tools setting. Global hooks and MCP configuration
+can run before a prompt. Helpers check the profile's `config/hooks.json` and
+`config/mcp_config.json` before launch and reject nonempty, malformed, or oversized
+configuration. `supportsTextGeneration=false` keeps such an instance out of system-model
+pickers. Empty managed profiles are supported. Do not describe prompt-time denial as a native
+sandbox.
+
+## OpenCode server ownership and catalog
+
+Native OpenCode event logs skip text deltas and running tool snapshots. Pending, completed,
+and failed tool states remain, including final output and errors. This filter does not change
+events sent to clients or orchestration storage.
+
+Each OpenCode provider instance owns one lazy local server for catalog discovery and
+text-generation helpers through [`OpenCodeServerOwner.ts`][opencode-server-owner]. Concurrent
+borrowers share startup. The server closes 30 seconds after the last borrower releases it, or
+when the provider instance closes. A failed or exited process can be started again on the next
+use. An externally configured OpenCode server remains externally owned.
+
+The local server and its SDK clients use one resolved password. An explicit provider password
+overrides `OPENCODE_SERVER_PASSWORD` in the spawned environment. Without an explicit password,
+the client uses the password from the environment that the process inherits. External servers use
+only their explicit provider password and never inherit the host's local password.
+
+Every server connection must pass the authenticated `/global/health` check before inventory or
+session operations start. The response must contain a valid version at or above 1.14.19. Local
+owners cache this result for the lifetime of the spawned process. External actions check once when
+they create their server connection, not for each model or SDK request.
+
+Chat adapters keep their own server per thread. They register a thread-specific `t3-code` MCP
+connection, while OpenCode stores MCP connections by directory. Sharing these chat servers
+without changing MCP routing would let two threads in one directory replace each other's
+connection.
+
+Chat adapters send the runtime mode as a session ruleset, but upstream OpenCode evaluates
+doom-loop and subagent asks against the agent ruleset only. In full access the adapter answers
+those asks itself so the user never sees an approval they already granted. It replies `once`
+rather than `always` because OpenCode stores `always` grants per directory, and on a shared
+external server that would widen what a supervised thread in the same directory may do.
+
+OpenCode loads its catalog through the HTTP API when an enabled provider instance starts. The
+provider registry keeps the snapshot in memory and persists it in the existing per-instance cache.
+Each `subscribeServerConfig` connection refreshes all providers, so a client reconnect reloads the
+OpenCode catalog from the current helper. The `serverRefreshProviders` request also refreshes it.
+Periodic OpenCode probes remain disabled. OpenCode reads credentials for each inventory request,
+but its native configuration files can remain cached for the lifetime of the helper process. The
+helper closes 30 seconds after its last inventory or text-generation borrower releases it. A
+refresh after that idle period starts a new helper and reads file changes. Repeated refreshes and
+active text-generation work can extend process reuse. Changes to the provider configuration or
+environment replace the instance and start a new discovery. Changes to unrelated settings only
+update snapshot enrichment. Other providers retain their existing refresh policy.
+
+T3 Code does not own an external OpenCode process. Native configuration changes there can require
+an external reload or restart before T3 Code's next refresh sees them.
+
+The shared server's idle shutdown does not clear the catalog. Failed discovery keeps the last
+known models, slash commands, and skills through the registry's existing merge rules. A successful
+empty inventory is authoritative. Existing threads keep their explicit model identifier and
+options when catalog metadata is missing; the catalog is not permission to choose a different
+model for a thread.
+
+## Model manifest
+
+The model picker's legacy section is driven by `apps/server/src/provider/model-manifest.json`, which
+lists the current (non-legacy) model slugs per driver kind. The `ModelManifest` service
+(`apps/server/src/provider/ModelManifest.ts`) refreshes that data from the same file on `main` via
+raw.githubusercontent.com, so moving a model in or out of the legacy section is a commit, not a
+release. Preference order is remote fetch, then the on-disk copy of the last successful fetch (in
+the state directory), then the bundled copy. Fetches are TTL-gated, run concurrently with provider
+probes, respect the `enableProviderUpdateChecks` setting, and never fail a provider check. The
+Codex and Claude drivers apply the classification to every snapshot with `applyModelManifest`;
+driver kinds absent from the manifest have no legacy concept.
+
+## Attachment access
+
+The server stores uploaded attachments in its attachment directory, outside the project workspace.
+`ProviderService` adds the absolute path of each attachment to the turn text, then passes every
+attachment to the provider adapter. Each adapter decides what its provider ingests natively:
+
+- Codex, Claude, Cursor, and Grok send images as native image inputs and skip generic files. For
+  these providers, generic files reach the agent only as file paths in the turn text.
+- Antigravity sends BMP, JPEG, PNG, and WebP images and common audio formats as native blocks,
+  text files as embedded resources, and PDFs as resource links. Other files are rejected with an
+  error instead of being dropped. The session advertises the ACP client file system capability,
+  so workspace reads and writes come back through `fs/read_text_file` and `fs/write_text_file`
+  and are confined to the workspace and the attachments directory.
+- OpenCode sends PNG/JPEG/GIF/WebP images, text files, and PDFs up to 20 MB as native file parts
+  with their real mime type. Everything else (ZIP and other binaries, image formats model APIs
+  reject, oversized files) falls back to the file path in the turn text, like the other providers.
+- Antigravity sends BMP/JPEG/PNG/WebP images as native image blocks, UTF-8 text as embedded
+  resources, and PDFs as local resource links. Text is limited to 1 MiB per file, images to
+  10 MiB each, and all attachments to 50 MiB per turn. Unsupported formats or oversized inputs
+  fail explicitly. Native path permissions still apply to PDFs.
+
+Claude receives the attachment directory as an allowed additional directory. Codex keeps its
+configured sandbox policy, so access depends on that policy and the selected runtime mode. OpenCode
+allows all paths in full-access mode and requests approval for directories outside the workspace in
+restricted modes. Cursor and Grok use their own provider permission rules.
+
+The server does not copy attachments into a project or bypass provider approval rules. If an agent
+cannot read an attachment, the user must approve the access or select a runtime mode that permits it.
+
+Updated attachment schemas tolerate unknown attachment members, but old image-only clients still
+cannot decode messages that contain file attachments. Client file-picking rollouts must account for
+this limit.
+
+Do not run an old image-only server against state that contains file attachments. Replay decodes
+each persisted event before projection. A file-bearing event can make `ProjectionPipeline` bootstrap
+and `OrchestrationEngine` startup fail for the entire environment, not only the affected thread.
+
+## How provider work is requested
+
+Clients never call a provider directly. They dispatch orchestration commands over the RPC method
+`orchestration.dispatchCommand`, defined with the rest of the orchestration surface in
+[`orchestration.ts`][contracts]. The client-dispatchable provider-facing commands are
+`thread.turn.start`, `thread.turn.interrupt`, `thread.approval.respond`,
+`thread.user-input.respond`, `thread.checkpoint.revert`, and `thread.session.stop`, plus the mode
+setters `thread.runtime-mode.set` and `thread.interaction-mode.set`.
+
+The engine persists an event for the command, and a server-side reactor performs the provider call.
+Provider output comes back as internal commands such as `thread.message.assistant.delta` and
+`thread.session.set`, which clients observe through `orchestration.subscribeThread`. See
+[overview.md](./overview.md) for the command/event loop.
+
+## Server-side workers
+
+Provider work flows through three queue-backed workers. All three are built with
+`makeDrainableWorker` from [`DrainableWorker.ts`][worker] and expose `drain` for deterministic test
+synchronization.
+
+1. [`ProviderRuntimeIngestion`][ingest] consumes provider runtime streams and emits orchestration
+   commands.
+2. [`ProviderCommandReactor`][cmd] reacts to orchestration intent events and dispatches provider
+   calls.
+3. [`CheckpointReactor`][checkpoint] captures workspace checkpoints on turn start and completion, and
+   performs reverts.
+
+### Buffered assistant delivery
+
+A thread in `buffered` assistant delivery mode accumulates assistant text instead of streaming each
+delta. The buffer is not held until turn completion. In [`ProviderRuntimeIngestion`][ingest],
+`MAX_BUFFERED_ASSISTANT_CHARS` is 24,000: the append that would exceed it invalidates the buffer and
+spills the whole accumulated text as one delta. The buffer also flushes at interaction boundaries,
+when a request opens (approval) or user input is requested, via
+`flushBufferedAssistantMessagesForTurn`.

+       * - provider accepts interrupt, then completes normally instead;
+       * - provider accepts interrupt but never terminalizes;

A great plan is very detailed-intent- and implementation-wise-so that it can be handed to another engineer or agent to be implemented right away. It must be **decision complete**, where the implementer does not need to make any decisions.\n\n## Mode rules (strict)\n\nYou are in **Plan Mode** until a developer message explicitly ends it.\n\nPlan Mode is not changed by user intent, tone, or imperative language. If a user asks for execution while still in Plan Mode, treat it as a request to **plan the execution**, not perform it.\n\n## Plan Mode vs update_plan tool\n\nPlan Mode is a collaboration mode that can involve requesting user input and eventually issuing a `<proposed_plan>` block.\n\nSeparately, `update_plan` is a checklist/progress/TODOs tool; it does not enter or exit Plan Mode. Do not confuse it with Plan mode or try to use it while in Plan mode. If you try to use `update_plan` in Plan mode, it will return an error.\n\n## Execution vs. mutation in Plan Mode\n\nYou may explore and execute **non-mutating** actions that improve the plan. You must not perform **mutating** actions.\n\n### Allowed (non-mutating, plan-improving)\n\nActions that gather truth, reduce ambiguity, or validate feasibility without changing repo-tracked state. Examples:\n\n* Reading or searching files, configs, schemas, types, manifests, and docs\n* Static analysis, inspection, and repo exploration\n* Dry-run style commands when they do not edit repo-tracked files\n* Tests, builds, or checks that may write to caches or build artifacts (for example, `target/`, `.cache/`, or snapshots) so long as they do not edit repo-tracked files\n\n### Not allowed (mutating, plan-executing)\n\nActions that implement the plan or change repo-tracked state. Examples:\n\n* Editing or writing files\n* Running formatters or linters that rewrite files\n* Applying patches, migrations, or codegen that updates repo-tracked files\n* Side-effectful commands whose purpose is to carry out the plan rather than refine it\n\nWhen in doubt: if the action would reasonably be described as \"doing the work\" rather than \"planning the work,\" do not do it.\n\n## PHASE 1 - Ground in the environment (explore first, ask second)\n\nBegin by grounding yourself in the actual environment. Eliminate unknowns in the prompt by discovering facts, not by asking the user. Resolve all questions that can be answered through exploration or inspection. Identify missing or ambiguous details only if they cannot be derived from the environment. Silent exploration between turns is allowed and encouraged.\n\nBefore asking the user any question, perform at least one targeted non-mutating exploration pass (for example: search relevant files, inspect likely entrypoints/configs, confirm current implementation shape), unless no local environment/repo is available.\n\nException: you may ask clarifying questions about the user's prompt before exploring, ONLY if there are obvious ambiguities or contradictions in the prompt itself. However, if ambiguity might be resolved by exploring, always prefer exploring first.\n\nDo not ask questions that can be answered from the repo or system (for example, \"where is this struct?\" or \"which UI component should we use?\" when exploration can make it clear). Only ask once you have exhausted reasonable non-mutating exploration.\n\n## PHASE 2 - Intent chat (what they actually want)\n\n* Keep asking until you can clearly state: goal + success criteria, audience, in/out of scope, constraints, current state, and the key preferences/tradeoffs.\n* Bias toward questions over guessing: if any high-impact ambiguity remains, do NOT plan yet-ask.\n\n## PHASE 3 - Implementation chat (what/how we'll build)\n\n* Once intent is stable, keep asking until the spec is decision complete: approach, interfaces (APIs/schemas/I/O), data flow, edge cases/failure modes, testing + acceptance criteria, rollout/monitoring, and any migrations/compat constraints.\n\n## Asking questions\n\nCritical rules:\n\n* Strongly prefer using the `request_user_input` tool to ask any questions.\n* Offer only meaningful multiple-choice options; don't include filler choices that are obviously wrong or irrelevant.\n* In rare cases where an unavoidable, important question can't be expressed with reasonable multiple-choice options (due to extreme ambiguity), you may ask it directly without the tool.\n\nYou SHOULD ask many questions, but each question must:\n\n* materially change the spec/plan, OR\n* confirm/lock an assumption, OR\n* choose between meaningful tradeoffs.\n* not be answerable by non-mutating commands.\n\nUse the `request_user_input` tool only for decisions that materially change the plan, for confirming important assumptions, or for information that cannot be discovered via non-mutating exploration.\n\n## Two kinds of unknowns (treat differently)\n\n1. **Discoverable facts** (repo/system truth): explore first.\n\n   * Before asking, run targeted searches and check likely sources of truth (configs/manifests/entrypoints/schemas/types/constants).\n   * Ask only if: multiple plausible candidates; nothing found but you need a missing identifier/context; or ambiguity is actually product intent.\n   * If asking, present concrete candidates (paths/service names) + recommend one.\n   * Never ask questions you can answer from your environment (e.g., \"where is this struct\").\n\n2. **Preferences/tradeoffs** (not discoverable): ask early.\n\n   * These are intent or implementation preferences that cannot be derived from exploration.\n   * Provide 2-4 mutually exclusive options + a recommended default.\n   * If unanswered, proceed with the recommended option and record it as an assumption in the final plan.\n\n## Finalization rule\n\nOnly output the final plan when it is decision complete and leaves no decisions to the implementer.\n\nWhen you present the official plan, wrap it in a `<proposed_plan>` block so the client can render it specially:\n\n1) The opening tag must be on its own line.\n2) Start the plan content on the next line (no text on the same line as the tag).\n3) The closing tag must be on its own line.\n4) Use Markdown inside the block.\n5) Keep the tags exactly as `<proposed_plan>` and `</proposed_plan>` (do not translate or rename them), even if the plan content is in another language.\n\nExample:\n\n<proposed_plan>\nplan content\n</proposed_plan>\n\nplan content should be human and agent digestible. The final plan must be plan-only and include:\n\n* A clear title\n* A brief summary section\n* Important changes or additions to public APIs/interfaces/types\n* Test cases and scenarios\n* Explicit assumptions and defaults chosen where needed\n\nDo not ask \"should I proceed?\" in the final output. The user can easily switch out of Plan mode and request implementation if you have included a `<proposed_plan>` block in your response. Alternatively, they can decide to stay in Plan mode and continue refining the plan.\n\nOnly produce at most one `<proposed_plan>` block per turn, and only when you are presenting a complete spec.\n</collaboration_mode>","model":"gpt-5.4","reasoning_effort":"medium"}},"approvalsReviewer":"user"}}}

A great plan is very detailed-intent- and implementation-wise-so that it can be handed to another engineer or agent to be implemented right away. It must be **decision complete**, where the implementer does not need to make any decisions.\n\n## Mode rules (strict)\n\nYou are in **Plan Mode** until a developer message explicitly ends it.\n\nPlan Mode is not changed by user intent, tone, or imperative language. If a user asks for execution while still in Plan Mode, treat it as a request to **plan the execution**, not perform it.\n\n## Plan Mode vs update_plan tool\n\nPlan Mode is a collaboration mode that can involve requesting user input and eventually issuing a `<proposed_plan>` block.\n\nSeparately, `update_plan` is a checklist/progress/TODOs tool; it does not enter or exit Plan Mode. Do not confuse it with Plan mode or try to use it while in Plan mode. If you try to use `update_plan` in Plan mode, it will return an error.\n\n## Execution vs. mutation in Plan Mode\n\nYou may explore and execute **non-mutating** actions that improve the plan. You must not perform **mutating** actions.\n\n### Allowed (non-mutating, plan-improving)\n\nActions that gather truth, reduce ambiguity, or validate feasibility without changing repo-tracked state. Examples:\n\n* Reading or searching files, configs, schemas, types, manifests, and docs\n* Static analysis, inspection, and repo exploration\n* Dry-run style commands when they do not edit repo-tracked files\n* Tests, builds, or checks that may write to caches or build artifacts (for example, `target/`, `.cache/`, or snapshots) so long as they do not edit repo-tracked files\n\n### Not allowed (mutating, plan-executing)\n\nActions that implement the plan or change repo-tracked state. Examples:\n\n* Editing or writing files\n* Running formatters or linters that rewrite files\n* Applying patches, migrations, or codegen that updates repo-tracked files\n* Side-effectful commands whose purpose is to carry out the plan rather than refine it\n\nWhen in doubt: if the action would reasonably be described as \"doing the work\" rather than \"planning the work,\" do not do it.\n\n## PHASE 1 - Ground in the environment (explore first, ask second)\n\nBegin by grounding yourself in the actual environment. Eliminate unknowns in the prompt by discovering facts, not by asking the user. Resolve all questions that can be answered through exploration or inspection. Identify missing or ambiguous details only if they cannot be derived from the environment. Silent exploration between turns is allowed and encouraged.\n\nBefore asking the user any question, perform at least one targeted non-mutating exploration pass (for example: search relevant files, inspect likely entrypoints/configs, confirm current implementation shape), unless no local environment/repo is available.\n\nException: you may ask clarifying questions about the user's prompt before exploring, ONLY if there are obvious ambiguities or contradictions in the prompt itself. However, if ambiguity might be resolved by exploring, always prefer exploring first.\n\nDo not ask questions that can be answered from the repo or system (for example, \"where is this struct?\" or \"which UI component should we use?\" when exploration can make it clear). Only ask once you have exhausted reasonable non-mutating exploration.\n\n## PHASE 2 - Intent chat (what they actually want)\n\n* Keep asking until you can clearly state: goal + success criteria, audience, in/out of scope, constraints, current state, and the key preferences/tradeoffs.\n* Bias toward questions over guessing: if any high-impact ambiguity remains, do NOT plan yet-ask.\n\n## PHASE 3 - Implementation chat (what/how we'll build)\n\n* Once intent is stable, keep asking until the spec is decision complete: approach, interfaces (APIs/schemas/I/O), data flow, edge cases/failure modes, testing + acceptance criteria, rollout/monitoring, and any migrations/compat constraints.\n\n## Asking questions\n\nCritical rules:\n\n* Strongly prefer using the `request_user_input` tool to ask any questions.\n* Offer only meaningful multiple-choice options; don't include filler choices that are obviously wrong or irrelevant.\n* In rare cases where an unavoidable, important question can't be expressed with reasonable multiple-choice options (due to extreme ambiguity), you may ask it directly without the tool.\n\nYou SHOULD ask many questions, but each question must:\n\n* materially change the spec/plan, OR\n* confirm/lock an assumption, OR\n* choose between meaningful tradeoffs.\n* not be answerable by non-mutating commands.\n\nUse the `request_user_input` tool only for decisions that materially change the plan, for confirming important assumptions, or for information that cannot be discovered via non-mutating exploration.\n\n## Two kinds of unknowns (treat differently)\n\n1. **Discoverable facts** (repo/system truth): explore first.\n\n   * Before asking, run targeted searches and check likely sources of truth (configs/manifests/entrypoints/schemas/types/constants).\n   * Ask only if: multiple plausible candidates; nothing found but you need a missing identifier/context; or ambiguity is actually product intent.\n   * If asking, present concrete candidates (paths/service names) + recommend one.\n   * Never ask questions you can answer from your environment (e.g., \"where is this struct\").\n\n2. **Preferences/tradeoffs** (not discoverable): ask early.\n\n   * These are intent or implementation preferences that cannot be derived from exploration.\n   * Provide 2-4 mutually exclusive options + a recommended default.\n   * If unanswered, proceed with the recommended option and record it as an assumption in the final plan.\n\n## Finalization rule\n\nOnly output the final plan when it is decision complete and leaves no decisions to the implementer.\n\nWhen you present the official plan, wrap it in a `<proposed_plan>` block so the client can render it specially:\n\n1) The opening tag must be on its own line.\n2) Start the plan content on the next line (no text on the same line as the tag).\n3) The closing tag must be on its own line.\n4) Use Markdown inside the block.\n5) Keep the tags exactly as `<proposed_plan>` and `</proposed_plan>` (do not translate or rename them), even if the plan content is in another language.\n\nExample:\n\n<proposed_plan>\nplan content\n</proposed_plan>\n\nplan content should be human and agent digestible. The final plan must be plan-only and include:\n\n* A clear title\n* A brief summary section\n* Important changes or additions to public APIs/interfaces/types\n* Test cases and scenarios\n* Explicit assumptions and defaults chosen where needed\n\nDo not ask \"should I proceed?\" in the final output. The user can easily switch out of Plan mode and request implementation if you have included a `<proposed_plan>` block in your response. Alternatively, they can decide to stay in Plan mode and continue refining the plan.\n\nOnly produce at most one `<proposed_plan>` block per turn, and only when you are presenting a complete spec.\n</collaboration_mode>","model":"gpt-5.4","reasoning_effort":"medium"}},"approvalsReviewer":"user"}}}

Parse NDJSON fixtures with:\n   - first line: `transcript_start`\n   - remaining lines: replay entries already compatible with `CodexAppServerReplayEntry`\n3. Convert each file into `CodexAppServerReplayTranscript`.\n4. Validate all lines through Effect Schema, returning schema-serializable errors with file path, line number, scenario, and parse/schema cause.\n5. Export fixture helpers from `package.json` as `./replay-fixtures`.\n\n## Public API\nAdd:\n```ts\nloadReplayFixture(path: string): Effect.Effect<CodexAppServerReplayTranscript, ReplayFixtureError>\nloadReplayFixtures(dir: string): Effect.Effect<ReadonlyArray<CodexAppServerReplayTranscript>, ReplayFixtureError>\n```\n\nAdd error types:\n```ts\nReplayFixtureReadError\nReplayFixtureJsonParseError\nReplayFixtureSchemaError\nReplayFixtureEmptyError\nReplayFixtureMissingTranscriptStartError\n```\n\n## Tests\nAdd tests covering:\n1. `simple.ndjson` loads into a valid transcript.\n2. Loaded `simple.ndjson` replays successfully through `layerReplay`.\n3. Malformed JSON reports file and line number.\n4. Missing `transcript_start` fails deterministically.\n5. Invalid entry shape fails schema validation.\n6. Fixture loading preserves entry order exactly.\n\n## Determinism Rules\n1. Do not rewrite existing fixture contents during replay.\n2. Keep normalization limited to existing replay comparison logic.\n3. Fixture loader must not depend on wall-clock time, current cwd, network, or process environment except the explicit file path input.\n4. Fixture order from directory loading should be lexicographic by filename.\n\n## Verification\nRun before completion:\n```sh\nbun fmt\nbun lint\nbun typecheck\nbun run test\n```\n\n## Assumptions\n1. Existing `test/fixtures/codex-app-server-probes/*.ndjson` files are the canonical initial deterministic fixture corpus.\n2. The current replay engine remains responsible for protocol-level matching.\n3. Fixture support is package-local and should not introduce runtime logic into contracts/shared packages.\n"},"threadId":"019db22b-08cd-7e12-b967-cf6ab32dd408","turnId":"019db22b-08d6-7bb3-9b7d-2ae5b8661a04"}}}

Proposing sweeping changes that improve long-term maintainability is encouraged.\n\n## Core Priorities\n\n1. Performance first.\n2. Reliability first.\n3. Keep behavior predictable under load and during failures (session restarts, reconnects, partial streams).\n\nIf a tradeoff is required, choose correctness and robustness over short-term convenience.\n\n## Maintainability\n\nLong term maintainability is a core priority. If you add new functionality, first check if there is shared logic that can be extracted to a separate module. Duplicate logic across multiple files is a code smell and should be avoided. Don't be afraid to change existing code. Don't take shortcuts by just adding local logic to solve a problem.\n\n## Package Roles\n\n- `apps/server`: Node.js WebSocket server. Wraps Codex app-server (JSON-RPC over stdio), serves the React web app, and manages provider sessions.\n- `apps/web`: React/Vite UI. Owns session UX, conversation/event rendering, and client-side state. Connects to the server via WebSocket.\n- `packages/contracts`: Shared effect/Schema schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types. Keep this package schema-only — no runtime logic.\n- `packages/shared`: Shared runtime utilities consumed by both server and web. Uses explicit subpath exports (e.g. `@t3tools/shared/git`) — no barrel index.\n\n## Codex App Server (Important)\n\nT3 Code is currently Codex-first. The server starts `codex app-server` (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.\n\nHow we use it in this codebase:\n\n- Session startup/resume and turn lifecycle are brokered in `apps/server/src/codexAppServerManager.ts`.\n- Provider dispatch and thread event logging are coordinated in `apps/server/src/providerManager.ts`.\n- WebSocket server routes NativeApi methods in `apps/server/src/wsServer.ts`.\n- Web app consumes orchestration domain events via WebSocket push on channel `orchestration.domainEvent` (provider runtime activity is projected into orchestration events server-side).\n\nDocs:\n\n- Codex App Server docs: https://developers.openai.com/codex/sdk/#app-server\n\n## Reference Repos\n\n- Open-source Codex repo: https://github.com/openai/codex\n- Codex-Monitor (Tauri, feature-complete, strong reference implementation): https://github.com/Dimillian/CodexMonitor\n\nUse these as implementation references when designing protocol handling, UX flows, and operational safeguards.\n\n</INSTRUCTIONS><environment_context>\n  <cwd>/Users/julius/.t3/worktrees/codething-mvp/t3code-c1e5e1d1</cwd>\n  <shell>zsh</shell>\n  <current_date>2026-04-28</current_date>\n  <timezone>America/Los_Angeles</timezone>\n</environment_context>\n\nUser:\nFor this fork-boundary fixture, respond with exactly: fork boundary alpha\n\nAssistant:\nfork boundary alpha\n\nUser:\nRepeat the user-visible conversation so far verbatim.

+
+Portable provider and fork handoffs are textual summaries. They do not claim native provider context
+parity.
+
+`ContextHandoffServiceV2` includes user messages, assistant messages, command executions, file
+changes, checkpoints, and prior handoffs. It skips other turn item types. For text-bearing items,
+`compactText` replaces every whitespace run with one space, trims the result, and returns at most
+240 characters. A truncated value contains the first 237 characters followed by `...`. File changes
+carry the filename, while checkpoints carry only the number of files.
+
+Provider handoffs use either the full eligible app history or the delta since that provider last
+participated. Fork merge-back handoffs summarize eligible delta items from the child. Neither path
+reconstructs provider-native session state, tool state, approvals, or omitted text.
+
+Legacy v1 continuation uses a separate algorithm. It considers only user and assistant messages,
+walks backward from the newest message, and builds a transcript suffix within a 32,000-character
+budget. Do not describe that migration budget as the limit for portable handoffs, and do not describe
+the 240-character prefix as a migration rule.

+# Legacy orchestration migration
+
+Orchestration v2 imports v1 threads in place. It creates v2 thread shell events first and imports
+the complete user and assistant transcript lazily when a client reads or continues the thread. The
+v1 projection tables remain the import source and provide a read-only recovery source if an import
+needs investigation.
+
+## Imported data
+
+The shell import preserves the project and thread identifiers, title, provider and model selection,
+runtime and interaction modes, branch, worktree path, creation and update times, archive and delete
+times, settlement override and timestamps, snooze timestamps, pin timestamp and order, and linked
+pull request. The metadata repair path fills snooze, pin order, `unsettledAt`, and linked pull request
+fields for threads imported before those fields were covered.
+
+Transcript import reads user and assistant rows from `projection_thread_messages`. It preserves
+message identifiers, text, supported attachments, timestamps, role, and ordering. A message that was
+still streaming becomes an interrupted turn item.
+
+The importer does not translate provider session identity, native provider runs, checkpoints and
+diffs, activities and tool calls, approvals, or proposed plans. V2 therefore must not present those
+records as migrated history.
+
+## First continuation
+
+A migrated thread has no active provider thread. Its first continuation creates a fresh provider
+session and sends a legacy handoff built only from user and assistant messages. The handoff selects
+the newest transcript suffix within a 32,000-character budget, including section labels and the
+import notice. This budget is separate from portable provider handoffs.
+
+## Recovery
+
+There is no supported whole-thread export API. Recovery uses an untouched copy of the environment's
+`userdata` directory and opens that copy with SQLite's read-only mode. The user guide documents the
+queries against `projection_threads` and `projection_thread_messages`. Never start a server against
+the recovery copy because startup can run migrations and write new state.

+A provider turn ending and its follow-up work settling are separate milestones. Orchestration
+records provider turn and run state independently from
+[run finalization](../../apps/server/src/orchestration-v2/RunFinalizationService.ts). A late
+checkpoint or diff must not extend the recorded provider duration or keep the client showing
+provider work as active. PR discovery after completion also checks that the checkout still matches
+the thread's non-default branch and that a newer run is not active.
 
 [Checkpoints](../../apps/server/src/checkpointing/CheckpointStore.ts) use hidden Git refs to
 capture workspace state without adding commits to the user's branch. A revert must coordinate
 workspace state with the provider conversation. A provider that cannot roll back its conversation
 must reject that operation before changing the filesystem.
 
+Thread settlement is server-owned. The
+[settlement service](../../apps/server/src/orchestration-v2/ThreadSettlementService.ts) evaluates PR
+and inactivity settings without a connected client. Merge notifications invalidate cached PR state
+and trigger a check. The guarded `thread.auto-settle` command rejects newer activity, explicit
+settlement overrides, and live or blocked work. It records the activity timestamp for stable
+sorting and detaches idle provider sessions. Clients render the persisted result; they do not
+derive settlement from their own clocks or PR caches.

+must use persisted state and events, not test instrumentation or assumptions about elapsed time.

+# Performance regression checks
+
+The v2 transport has a focused regression command:
+
+```bash
+vp run test:perf:v2-wire
+```
+
+It exercises the real v2 projection and client reducers. This matters because the older
+built-app benchmark fixtures seed v1 orchestration events; running those fixtures against a v2
+client can produce reassuring timings while missing the active transport path.
+
+The v2 checks pin these invariants:
+
+- Client cold opens use a recent timeline window capped at 75 rows and about 1 MiB of encoded
+  timeline data.
+- The bounded snapshot does not retain the full duplicate conversation-message table.
+- Older activity is fetched in bounded HTTP pages and merged without disturbing the live scroll
+  window.
+- Resume catch-up replays at most 128 thread events and 1 MiB of projected event JSON before
+  replacing stale state with a current snapshot.
+- Oversized dynamic-tool results and detail strings are reduced only at the wire boundary; the
+  persisted event remains complete.
+- The initial shell contains active navigation rows only. Archived rows use the dedicated archive
+  query, and transcript message bodies stay in thread detail regardless of message size.
+- Shell resume sends deltas plus compact repository-enrichment metadata, not another full project
+  and thread snapshot.
+- Known idle sends and interrupts do not fetch a full thread projection before dispatch.
+
+When changing projection schemas, paging, shell synchronization, or thread state, run this command
+alongside the focused package typechecks and a real-client pass on every affected surface. Payload
+budgets belong in these tests rather than logs or one-off recordings so regressions fail locally.
+
+## Event store and startup
+
+Sequence cursors must seek an index rather than scan retained history. The application sequence
+index contains project events and v2 thread events; the per-thread sequence index contains only v2
+thread events. Legacy-only and unknown threads must return zero without scanning other threads.
+Catch-up queries keep sequence ranges and optional thread or command predicates indexable.
+
+Startup selects recovery candidates from current projection state before reading full thread
+projections. Candidate selection includes queued runs, pending runtime requests, live provider
+sessions, background work, and unfinished delegated deliveries. Archived threads still participate
+where recovery requires them. Completed thread history is not loaded merely to discover that no
+work remains.
+
+Projection verification decodes canonical rows in bounded pages, including shared provider records
+and fork ancestry. Rebuild replays event pages through a fixed sequence within its transaction;
+it must not collect the entire event log before projecting it.
+
+The focused regression coverage lives in `OrchestrationEventStore.sequence.test.ts`,
+`ProjectionRecovery.test.ts`, and the provider runtime recovery tests under `apps/server/src`.
+
+## Background work and navigation
+
+The settlement worker reads active, unpinned threads without explicit settlement overrides from
+`ProjectionStore.getSettlementCandidates`. It reads the latest run and user-message timestamps,
+rejects active runs and pending requests, and checks background work using the same derivation as
+the shell. It does not load archived histories, fork ancestry, transcript counts, or provider
+sessions. The orchestrator still validates the current thread before applying settlement.
+
+Read receipts use `ProjectionStore.getThread` to load only canonical thread metadata. A visit
+advances `lastVisitedAt` monotonically without changing `updatedAt` or decoding history. Shell
+queries use a covering thread/run index for item counts and a partial index for nonterminal
+background items, including idle items. Latest user-message reads use an index ordered by update
+time.
+
+Command palette results keep live VCS and linked pull-request queries leased to the visible
+viewport, including a small overscan region. Cached badges remain available while leases are
+released. Local Git status reads skip divergence calculations; callers that need ahead/behind
+counts keep the full status path. Cached fetch failures share the existing backoff and log only
+the actual failed attempt. Unchanged desktop environment bootstrap reads retain their array
+identity so polling does not invalidate subscribers.
+
+Relay awareness queues one pending publication per thread and retains a follow-up when the thread
+changes during a send. Transcript deltas and tool output do not enqueue awareness work. Run,
+request, and relevant thread metadata events do. Configuration is checked before shell reads, and
+connection changes invalidate published identities so relinking can publish unchanged state.
+Failed publications retry the latest state up to five times with exponential delays. A new
+relevant event resets the budget; successful publication, disabling, or unlinking cancels retries.
+After the budget is exhausted, publication waits for another relevant event instead of generating
+continuous traffic during an outage.
+
+Focused coverage: `ProjectionSettlement.test.ts`, `ThreadSettlementService.test.ts`,
+`runtimeLayer.test.ts`, `AgentAwarenessRelay.test.ts`, `GitVcsDriverCore.test.ts`,
+`ThreadStatusIndicators.subscriptions.test.tsx`, and `desktopLocal.test.ts`.

+# Orchestration V2
+
+This document set describes the target architecture for the next orchestration model. It is not a patch plan for the current implementation and it intentionally ignores migration/backward compatibility. Those concerns should be handled after the target model is coherent.
+
+V2 is an orchestrator rewrite, not a rewrite of the whole app domain platform. Existing non-orchestration domains, persistence/migration infrastructure, websocket/RPC infrastructure, and projection streaming semantics should be retained unless V2 exposes a concrete orchestration-specific gap.
+
+V2 is designed around the real provider behavior observed in the Codex app-server probes, but it is not Codex-specific. Codex is treated as the richest protocol we currently have; weaker providers are adapted into the same model with app-owned ids and explicit capability flags.
+
+## Documents
+
+- [Core Graph And Data Model](./core-graph-and-data-model.md)
+- [Entity IDs And Correlation](./entity-ids-and-correlation.md)
+- [Feature Lifecycles](./feature-lifecycles.md)
+- [Thread Lineage And Context Transfer](./thread-lineage-and-context-transfer.md)

+- [Orchestrator MCP Server](./orchestrator-mcp-server.md)
+- [Provider Capability System](./provider-capability-system.md)
+- [Testing Strategy](./testing-strategy.md)
+
+## Primary Goals
+
+- Preserve provider-native lifecycle fidelity without leaking provider ids into app identity.
+- Model root turns, subagents, tools, approvals, plans, and checkpoints as one execution graph.
+- Make root-run completion the only event that completes a user-visible turn.
+- Support forking from normal threads and completed subagent/provider threads.
+- Support changing providers between runs as a first-class context handoff.
+- Model forks, provider handoffs, merge-back, and subagents through shared thread lineage and context transfer primitives.
+- Support providers with weak or missing ids through deterministic app-owned id allocation.
+- Make feature behavior capability-driven, not provider-name-driven.
+
+## Key Invariants
+
+1. App ids are primary. Provider ids are refs.
+2. Provider events are never rewritten to look like another provider event.
+3. Child execution completion never closes the parent run.
+4. Checkpoints attach to checkpointable execution scopes. Root-run checkpoints advance app run history; child/subagent checkpoints are nested and do not advance the parent run count.
+5. Rollback is expressed in app run count and reconciled with provider conversation state.
+6. Every command targets app ids; adapters translate to provider refs at the edge.
+7. Missing provider capability is represented explicitly and handled by policy.
+8. Provider switches create explicit context handoff artifacts; they are not hidden prompt hacks.
+9. Forks record app-level lineage first. Provider-native forks and portable context handoffs are lazy resolution strategies chosen when a run starts.
+10. Tests should prefer replay-backed integration coverage over mocked unit tests. The only normal substitute in orchestration tests is the provider runtime transport.
+
+## Conceptual Layers
+
+```text
+Native provider protocol
+  -> Rotating raw provider diagnostics
+  -> Provider adapter / normalizer
+  -> V2 orchestration event store using existing persistence patterns
+  -> Runtime execution graph
+  -> Conversation projection
+  -> UI / API views
+```
+
+Raw provider diagnostics store what the provider actually sent or received for debugging and replay capture. The durable app state is the normalized orchestration state: events/entities, correlation refs, projections, and command receipts. The runtime graph stores what provider behavior means. The conversation projection stores what users see.
+
+V2 should integrate with the existing orchestration command/event/projection infrastructure patterns rather than creating an unrelated event system. The V2-specific work is the graph model, provider lifecycle semantics, adapter contracts, normalizers, policies, and projections.
+
+While V1 is still present, V2 should own a V2 event schema and V2 event table. It should not force V2 semantics through the old `OrchestrationEvent` TypeScript union. The old union is a V1 semantic model, not the target V2 event vocabulary. A later migration can replace V1 with V2, but the target model should stay V2-native.
+
+## Minimal Mental Model
+
+```text
+AppThread
+  Run 1
+    root ExecutionNode
+      tool ExecutionNode
+      approval ExecutionNode
+      subagent ExecutionNode
+        ProviderThread
+          child root ExecutionNode
+  Run 2
+    root ExecutionNode
+```
+
+An app thread is the user-visible conversation. A run is the counted user-visible turn. Execution nodes are the tree of work inside the run. Provider threads are provider-native conversation handles that can be attached to app threads or nested execution nodes.
+
+Provider switches do not create new app threads. They create or reactivate provider threads and attach context handoff summaries to the next run.
+
+Forks do create new app threads, but they should not force provider selection at fork time. Forking records thread lineage and a pending source point. The first run on the fork resolves that source point through native provider fork when possible or portable context transfer when needed.
+
+## Probe-Derived Requirements
+
+The Codex app-server probes showed several protocol realities that the V2 model must preserve:
+
+- `thread/status/changed` can become idle before or around completion, but `turn/completed` is the authoritative turn terminal event.
+- `turn/interrupt` completes as a request first; the interrupted terminal state arrives later through `turn/completed`.
+- Approval requests are provider-initiated JSON-RPC requests scoped to provider thread, turn, and item.
+- `thread/rollback` returns an authoritative provider thread snapshot after rollback.
+- Subagent child `turn/completed` events can occur before the parent/root turn completes.
+- Child provider turns are real provider turns and must not be remapped onto the parent provider turn id.
+
+These observations are why V2 separates app runs, provider turns, and execution nodes.
+
+## Existing Platform Boundaries
+
+V2 should reuse existing app infrastructure where that infrastructure is not the source of the orchestration bug class:
+
+- Command dispatch should keep the existing serialized/idempotent command handling and command receipt pattern.
+- Projection streams should keep the existing snapshot-plus-cursor semantics used by the current API.
+- Persistence should keep the existing SQLite/migration/repository infrastructure and projection-stream semantics.
+- Raw provider frames should continue to be diagnostic log data, with bounded retention through rotating logs.
+- Replay tests should replace only the provider transport/process boundary.
+
+V2 may add V2-native orchestration events, projection tables, command policies, and provider execution services. It should not add a durable raw-provider-event database or a separate generic event bus unless the existing infrastructure cannot satisfy a documented V2 requirement.
+
+V2 command dispatch returns the last committed stored-event sequence for accepted commands. Duplicate command ids must return the same receipt-backed result without re-running provider side effects. This is the API-level boundary the frontend uses for reconnect/recovery cursors.
+
+## Tracked Follow-Up: Durable Effect Outbox
+
+The current app pipeline uses domain events plus reactors to trigger provider side effects:
+
+```text
+command
+  -> domain event(s)
+  -> projection
+  -> reactor observes event
+  -> provider side effect
+  -> provider output ingestion
+  -> domain event(s)
+```
+
+This is valid, but it can become hard to trace because the provider side effect is implicit in a live subscription. If V2 needs stronger restart/recovery/debuggability, introduce a durable effect outbox for orchestration side effects:
+
+```text
+command
+  -> transaction:
+       append domain event(s)
+       append provider effect request(s)
+  -> projection
+  -> stream to UI
+
+effect worker
+  -> claim effect request
+  -> call provider
+  -> ingest provider output
+  -> append domain event(s)
+  -> mark effect request completed/failed
+```
+
+Example effect request:
+
+```ts
+type ProviderEffectRequest = {
+  id: ProviderEffectRequestId;
+  kind:
+    | "provider.turn.start"
+    | "provider.turn.interrupt"
+    | "provider.runtime-request.respond"
+    | "provider.thread.rollback"
+    | "provider.thread.fork";
+  status: "pending" | "running" | "completed" | "failed" | "cancelled";
+  threadId: ThreadId;
+  runId: RunId | null;
+  nodeId: NodeId | null;
+  provider: ProviderKind;
+  payload: unknown;
+  causationEventId: EventId;
+  commandId: CommandId | null;
+  attempts: number;
+  lastError: string | null;
+};
+```
+
+This should be treated as an infrastructure improvement, not a prerequisite for the first V2 slice. The first V2 implementation can use the existing reactor pattern, but it should keep the provider side-effect boundary clear enough that moving to an outbox later does not require redesigning the graph or provider adapters.

+# Core Graph And Data Model
+
+## Overview
+
+V2 models orchestration as a graph with a small number of durable entity types:
+
+```text
+Project
+  AppThread
+    Run
+      ExecutionNode tree
+    ProviderThread handles
+    Context transfers and handoffs
+    Checkpoints
+```
+
+The central separation is:
+
+- `AppThread`: the user-visible conversation in T3 Code.
+- `Run`: a counted user-visible turn on an app thread.
+- `ExecutionNode`: a unit of provider/runtime work inside a run.
+- `ProviderThread`: a provider-native conversation handle.
+- `ProviderSession`: a live or resumable provider process/runtime.
+- `ContextTransfer`: a provider-neutral relationship/source-point record used by forks, provider switches, merge-back, and subagents.
+- `ContextHandoff`: a materialized portable context artifact used when native transfer is unavailable or insufficient.
+
+Provider-specific lifecycle is preserved in provider refs and diagnostic raw-provider logs. App behavior is driven by app-owned ids, V2-native orchestration events, and graph relationships.
+
+V2 events are durable because they are the app state transition log. Raw provider frames are not durable app state. They may be attached by optional correlation ids such as `rawEventId`, but the canonical durable row is the normalized V2 event.
+
+Every committed V2 event has a store-assigned monotonically increasing `sequence`. Projection snapshots and websocket streams use that sequence as the cursor boundary:
+
+```text
+read snapshot at sequence N
+  -> stream committed V2 events where sequence > N
+```
+
+The sequence belongs to the stored event envelope, not the provider event and not the domain payload. Provider-native ordering is preserved separately through provider refs and diagnostic logs. Clients should treat the snapshot's `snapshotSequence` as the authoritative cursor and apply only subsequent events with a greater sequence.

+
+## AppThread
+
+An `AppThread` is the stable user-facing conversation. It owns messages, runs, checkpoints, and UI state. It does not have to map one-to-one with a provider-native thread forever.
+
+```ts
+type AppThread = {
+  id: ThreadId;
+  projectId: ProjectId;
+  title: string;
+  defaultProvider: ProviderKind;
+  modelSelection: ModelSelection;
+  runtimeMode: RuntimeMode;
+  interactionMode: InteractionMode;
+  branch: string | null;
+  worktreePath: string | null;
+  activeProviderThreadId: ProviderThreadId | null;
+  lineage: AppThreadLineage | null;
+  createdAt: string;
+  updatedAt: string;
+  archivedAt: string | null;
+  deletedAt: string | null;
+};
+```
+
+`activeProviderThreadId` points to the provider-native conversation currently backing the app thread. Forking, provider migration, or recovery may create new provider threads while preserving the same app thread, depending on the operation.
+
+`defaultProvider` is only the currently selected default for future runs. Historical runs retain their own provider and provider thread bindings.
+
+`lineage` is intentionally lightweight browsing metadata. Operational source points, lazy native fork resolution, portable context handoffs, merge-back deltas, and subagent result transfers live in `ContextTransfer` rows because an app thread can participate in more than one transfer over time.
+
+```ts
+type AppThreadLineage = {
+  parentThreadId: ThreadId | null;
+  relationshipToParent: "fork" | "subagent" | null;
+  rootThreadId: ThreadId;
+};
+```
+
+## Run
+
+A `Run` is the counted user-visible turn. This replaces using provider turn ids as the app-level lifecycle boundary.
+
+```ts
+type Run = {
+  id: RunId;
+  threadId: ThreadId;
+  ordinal: number;
+  provider: ProviderKind;
+  providerThreadId: ProviderThreadId | null;
+  userMessageId: MessageId;
+  rootNodeId: NodeId | null;
+  activeAttemptId: RunAttemptId | null;
+  status:
+    | "queued"
+    | "starting"
+    | "running"
+    | "waiting"
+    | "completed"
+    | "interrupted"
+    | "failed"
+    | "cancelled"
+    | "rolled_back";
+  requestedAt: string;
+  startedAt: string | null;
+  completedAt: string | null;
+  checkpointId: CheckpointId | null;
+  contextHandoffId: ContextHandoffId | null;
+  sourcePlanRef?: {
+    threadId: ThreadId;
+    planId: ProposedPlanId;
+  };
+};
+```
+
+Only a run with `countsForConversation = true` contributes to the user-visible turn count and checkpoint count.
+
+`providerThreadId` is the provider-native conversation used for this run. This makes mixed-provider app threads explicit: run 1 may be Codex, run 2 may be Claude, and run 3 may return to the original Codex provider thread.
+
+`contextHandoffId` points to a materialized handoff artifact consumed by this run. A run may also be associated with a broader `ContextTransfer` through the transfer's target/source fields. The handoff is the payload; the transfer is the durable relationship and policy record.
+
+## RunAttempt
+
+A `RunAttempt` represents one provider execution attempt for an app run. Most runs have exactly one attempt. Steering, retries, provider recovery, or provider-switch recovery may create more than one attempt.
+
+```ts
+type RunAttempt = {
+  id: RunAttemptId;
+  runId: RunId;
+  attemptOrdinal: number;
+  rootNodeId: NodeId;
+  provider: ProviderKind;
+  providerThreadId: ProviderThreadId;
+  providerTurnId: ProviderTurnId | null;
+  reason: "initial" | "steering_restart" | "retry" | "provider_recovery";
+  status:
+    "pending" | "running" | "completed" | "interrupted" | "failed" | "cancelled" | "superseded";
+  startedAt: string | null;
+  completedAt: string | null;
+};
+```
+
+Run attempts let app-level steering work even for providers that cannot steer an active native turn. The app can interrupt the active provider turn and create a replacement attempt under the same `RunId`.
+
+Only one attempt is the final selected attempt for run completion and checkpointing. Superseded/interrupted attempts remain in the execution graph for audit/debugging.
+
+## ExecutionNode
+
+An `ExecutionNode` is the generic unit of runtime work. It is the bridge between provider events and app behavior.
+
+```ts
+type ExecutionNode = {
+  id: NodeId;
+  threadId: ThreadId;
+  runId: RunId | null;
+  parentNodeId: NodeId | null;
+  rootNodeId: NodeId;
+  kind:
+    | "root_turn"
+    | "assistant_message"
+    | "reasoning"
+    | "plan"
+    | "todo_list"
+    | "tool_call"
+    | "approval_request"
+    | "user_input_request"
+    | "subagent"
+    | "hook"
+    | "system";
+  status:
+    | "pending"
+    | "running"
+    | "waiting"
+    | "completed"
+    | "interrupted"
+    | "failed"
+    | "cancelled"
+    | "rolled_back";
+  countsForRun: boolean;
+  providerThreadId: ProviderThreadId | null;
+  providerTurnId: ProviderTurnId | null;
+  nativeItemRef: ProviderRef | null;
+  runtimeRequestId: RuntimeRequestId | null;
+  checkpointScopeId: CheckpointScopeId | null;
+  startedAt: string | null;
+  completedAt: string | null;
+};
+```
+
+The root node of a run is the only node allowed to complete the run. Subagent nodes, tool nodes, approval nodes, and plan nodes may complete independently.
+
+## CheckpointScope
+
+A `CheckpointScope` describes a unit of filesystem state that can be checkpointed. Root runs and child execution nodes can both have checkpoint scopes.
+
+```ts
+type CheckpointScope = {
+  id: CheckpointScopeId;
+  threadId: ThreadId;
+  runId: RunId | null;
+  nodeId: NodeId;
+  parentScopeId: CheckpointScopeId | null;
+  providerThreadId: ProviderThreadId | null;
+  kind: "root_run" | "subagent" | "tool" | "provider_thread" | "manual";
+  ordinalWithinParent: number;
+  advancesAppRunCount: boolean;
+  cwd: string;
+  createdAt: string;
+};
+```
+
+Root run scopes have `advancesAppRunCount = true`. Child scopes, such as subagents, have `advancesAppRunCount = false` and are nested under the parent run's scope.
+
+## ProviderSession
+
+A `ProviderSession` is a live provider runtime process/session, such as a Codex app-server process or a Claude SDK session.
+
+```ts
+type ProviderSession = {
+  id: ProviderSessionId;
+  provider: ProviderKind;
+  status: "starting" | "ready" | "running" | "waiting" | "stopped" | "error";
+  cwd: string;
+  model: string | null;
+  capabilities: ProviderCapabilities;
+  createdAt: string;
+  updatedAt: string;
+  lastError: string | null;
+};
+```
+
+A provider session may host one or more provider threads if the provider supports it. If a provider only supports one active conversation per process, V2 still models that as one provider thread attached to the session.
+
+The session entity is durable metadata for a live-or-recoverable runtime, not the runtime handle itself. The in-memory process/client handle may disappear because the server restarted, an idle reaper released it, or the provider process crashed. In all cases, the app keeps the `ProviderSession`, `ProviderThread`, and native resume refs in durable state, then recreates the live runtime through the normal provider session manager path.
+
+Provider runtime ids and ordinals must not depend on adapter process memory. If a value is persisted or must survive recovery, it is allocated by the orchestrator/correlation/id services or derived from durable provider refs.
+
+## ProviderThread
+
+A `ProviderThread` is a provider-native conversation handle. It is addressable even when it is nested under a subagent execution node.
+
+```ts
+type ProviderThread = {
+  id: ProviderThreadId;
+  provider: ProviderKind;
+  providerSessionId: ProviderSessionId | null;
+  appThreadId: ThreadId | null;
+  ownerNodeId: NodeId | null;
+  nativeThreadRef: string | null;
+  nativeConversationHeadRef: ProviderRef | null;
+  status: "not_loaded" | "idle" | "active" | "archived" | "closed" | "error";
+  firstRunOrdinal: number | null;
+  lastRunOrdinal: number | null;
+  handoffIds: ContextHandoffId[];
+  forkedFrom: ProviderThreadForkSource | null;
+  createdAt: string;
+  updatedAt: string;
+};
+```
+
+`appThreadId` is set when the provider thread backs a first-class app thread. `ownerNodeId` is set when the provider thread is nested under an execution node, such as a subagent. A provider thread can later be forked or promoted into a first-class app thread.
+
+A provider thread may have gaps in its native run coverage. Example: runs 1-5 use Codex provider thread A, runs 6-8 use Claude provider thread B, and run 9 returns to Codex thread A with a handoff summary covering runs 6-8. In that case, Codex thread A remains the same provider thread, but it has an explicit `ContextHandoff` before run 9.
+
+## ContextTransfer
+
+A `ContextTransfer` records a source/target relationship and how context should move between them. It is the shared primitive for user forks, provider switching, merge-back, and subagents.
+
+```ts
+type ContextTransfer = {
+  id: ContextTransferId;
+  type: "fork" | "provider_handoff" | "merge_back" | "subagent_spawn" | "subagent_result";
+  sourceThreadId: ThreadId;
+  targetThreadId: ThreadId;
+  sourcePoint: ContextSourcePoint;
+  basePoint: ContextSourcePoint | null;
+  sourceProvider: ProviderKind | null;
+  targetProvider: ProviderKind | null;
+  status:
+    "pending" | "resolved_native" | "resolved_portable" | "failed" | "consumed" | "superseded";
+  resolution: ContextTransferResolution | null;
+  createdBy: "user" | "agent" | "system";
+  createdAt: string;
+  consumedAt: string | null;
+};
+```
+
+```ts
+type ContextSourcePoint = {
+  threadId: ThreadId;
+  runId: RunId | null;
+  checkpointId: CheckpointId | null;
+  turnItemId: TurnItemId | null;
+  providerThreadRef: NativeThreadRef | null;
+  providerTurnRef: NativeTurnRef | null;
+};
+
+type ContextTransferResolution =
+  | { strategy: "native_fork"; providerThreadRef: NativeThreadRef }
+  | { strategy: "portable_context"; contextHandoffId: ContextHandoffId }
+  | { strategy: "delta_context"; contextHandoffId: ContextHandoffId }
+  | { strategy: "checkpoint_context"; contextHandoffId: ContextHandoffId };
+```
+
+Creating a transfer should be cheap. Expensive context handoffs are materialized lazily when the target run starts and the selected provider is known.
+
+## ContextHandoff
+
+A `ContextHandoff` is a first-class artifact created when portable provider context must be bridged. It is most common when changing providers between runs, but it also applies when provider resume fails and a replacement provider thread must be seeded from app history.
+
+In the broader transfer model, `ContextTransfer` records source, target, and lifecycle. `ContextHandoff` is the materialized payload consumed by a run when native transfer cannot satisfy the relationship.
+
+```ts
+type ContextHandoff = {
+  id: ContextHandoffId;
+  transferId: ContextTransferId;
+  threadId: ThreadId;
+  targetRunId: RunId;
+  fromProviderThreadIds: ProviderThreadId[];
+  toProviderThreadId: ProviderThreadId;
+  coveredRunOrdinals: {
+    from: number;
+    to: number;
+  };
+  strategy:
+    | "delta_since_target_last_seen"
+    | "full_thread_summary"
+    | "checkpoint_summary"
+    | "manual_context";
+  status: "pending" | "ready" | "failed" | "superseded";
+  summaryMessageId: MessageId | null;
+  summaryText: string;
+  createdByProvider: ProviderKind | null;
+  createdAt: string;
+  updatedAt: string;
+};
+```
+
+The handoff is not just prompt text. It is part of the graph and can be inspected, regenerated, superseded, or audited.
+
+The preferred return-to-provider strategy is `delta_since_target_last_seen`: resume the previous provider thread and summarize only the runs that happened while that provider was inactive. Use `full_thread_summary` when resume fails, provider settings are incompatible, or the accumulated handoffs would create poor context quality.
+
+## ProviderTurn
+
+A `ProviderTurn` is the normalized handle for a provider-native turn.
+
+```ts
+type ProviderTurn = {
+  id: ProviderTurnId;
+  providerThreadId: ProviderThreadId;
+  nodeId: NodeId;
+  runAttemptId: RunAttemptId | null;
+  nativeTurnRef: string | null;
+  ordinal: number;
+  status: "pending" | "running" | "completed" | "interrupted" | "failed" | "cancelled";
+  startedAt: string | null;
+  completedAt: string | null;
+};
+```
+
+Codex has strong native turn ids. Weaker providers may only have ordinals. Both map into `ProviderTurnId`.
+
+## RuntimeRequest
+
+Requests represent provider-originated callbacks that require app/user response.
+
+```ts
+type RuntimeRequest = {
+  id: RuntimeRequestId;
+  nodeId: NodeId;
+  providerTurnId: ProviderTurnId | null;
+  nativeRequestRef: string | null;
+  kind:
+    "command" | "file-read" | "file-change" | "dynamic_tool_call" | "user_input" | "auth_refresh";
+  status: "pending" | "resolved" | "expired" | "cancelled";
+  responseCapability:
+    | { type: "live"; providerSessionId: ProviderSessionId }
+    | { type: "not_resumable"; reason: string };
+  createdAt: string;
+  resolvedAt: string | null;
+};
+```
+
+The permission kinds are the same canonical domain values used by V1 `ProviderRequestKind`.
+Adapters map provider-native callback names such as Codex `item/commandExecution/requestApproval`
+and Claude tool permission names into these app-level values.
+
+Requests may remain visible after restart, but they are only respondable if their `responseCapability` is live.
+
+## Messages
+
+Messages are part of the conversation projection, not the raw provider graph. They link back to runs and nodes when possible.
+
+```ts
+type ConversationMessage = {
+  id: MessageId;
+  threadId: ThreadId;
+  runId: RunId | null;
+  nodeId: NodeId | null;
+  role: "user" | "assistant" | "system";
+  text: string;
+  attachments: Attachment[];
+  streaming: boolean;
+  createdAt: string;
+  updatedAt: string;
+};
+```
+
+Provider message chunks are collected through items/content events and projected into messages. The projection may hide child/subagent messages by default while preserving them in the graph.
+
+## Plans, Questions, And Todo Lists
+
+V2 treats these as structured turn items or execution nodes.
+
+```ts
+type PlanArtifact = {
+  id: PlanId;
+  threadId: ThreadId;
+  runId: RunId | null;
+  nodeId: NodeId;
+  kind: "proposed_plan" | "todo_list" | "questions";
+  status: "draft" | "active" | "completed" | "superseded";
+  markdown?: string;
+  steps?: Array<{ id: string; text: string; status: "pending" | "running" | "completed" }>;
+  questions?: UserInputQuestion[];
+};
+```
+
+Codex `turn/plan/updated` maps to a `todo_list` artifact. Plan-mode final plan items map to `proposed_plan`. User-input question requests map to `questions` plus a `RuntimeRequest`.
+
+## Checkpoint
+
+Checkpoints attach to checkpoint scopes. A root run checkpoint is the user-visible conversation checkpoint. A child checkpoint records nested filesystem state for a subagent, tool, or provider thread without advancing the parent run count.
+
+```ts
+type Checkpoint = {
+  id: CheckpointId;
+  threadId: ThreadId;
+  scopeId: CheckpointScopeId;
+  runId: RunId | null;
+  nodeId: NodeId;
+  parentCheckpointId: CheckpointId | null;
+  ordinalWithinScope: number;
+  appRunOrdinal: number | null;
+  ref: string;
+  status: "ready" | "missing" | "error" | "stale";
+  files: CheckpointFileSummary[];
+  capturedAt: string;
+};
+```
+
+A child/subagent provider turn can create a child checkpoint. It does not create an app-run checkpoint unless it is running as a first-class app run in a forked/promoted thread.
+
+## Raw Provider Diagnostics
+
+Raw provider diagnostics are append-only evidence for debugging, support, and replay fixture generation. They should be written to bounded rotating log files, not treated as canonical durable SQLite state.
+
+```ts
+type RawProviderEvent = {
+  id: RawEventId;
+  provider: ProviderKind;
+  providerSessionId: ProviderSessionId;
+  sequence: number;
+  direction: "incoming" | "outgoing";
+  messageKind: "request" | "response" | "notification" | "error";
+  method: string | null;
+  jsonRpcId: string | number | null;
+  payload: unknown;
+  observedAt: string;
+};
+```
+
+No domain behavior should depend on parsing historic UI events if raw provider diagnostics are available. Production behavior should depend on normalized orchestration events/entities and provider refs. Raw provider frames are evidence and replay input, not the source of truth for normal app state.
+
+Normalized V2 entities should preserve enough correlation metadata to explain and route behavior:
+
+- provider kind.
+- provider session/thread/turn refs.
+- provider item/request refs when available.
+- native id strength.
+- diagnostic log location or raw frame reference when useful.
+
+The replay framework can use raw provider transcripts as input without requiring production SQLite to store every raw frame.
+
+## Projections
+
+V2 should expose separate projections:
+
+- Thread shell: fast sidebar list.
+- Thread detail: messages, runs, activities, checkpoints, plans.
+- Execution graph: debug/developer view of nodes and provider refs.
+- Provider sessions: live runtime/process state.
+- Pending requests: actionable approvals/user input.
+
+The UI can remain simple while the graph remains precise.
+
+Projection streaming should use the existing app snapshot-plus-cursor contract. A thread-detail subscription should return a projection snapshot at sequence `N`, then stream only events after `N`. The frontend should not receive events already reflected in the snapshot. Reconnects may reset from a fresh snapshot instead of replaying local client state; the fresh snapshot and its `snapshotSequence` become the new cursor boundary.
+
+## Turn Item Projection
+
+The frontend should not reconstruct display order by merging `messages`, `plans`, checkpoints, approvals, and activities itself. V2 exposes an ordered `turnItems` projection for thread detail rendering.
+
+`turnItems` are projection records, not the canonical source of truth. The canonical graph remains normalized in runs, attempts, nodes, requests, messages, plans, and checkpoints. Provider-native item refs live directly on nodes and turn items where correlation is needed.
+
+Forked threads also expose a derived `visibleTurnItems` projection. `turnItems` remains the canonical
+items emitted on that app thread. `visibleTurnItems` is the user-visible ordered read model: it may
+reference inherited source items through the fork source point, include synthetic lifecycle markers
+such as "forked from conversation", and then continue with local target-thread items. This keeps
+storage normalized while giving thread detail views and tests one backend-owned surface to assert.
+
+Known common tools should have structured item variants so the frontend can render stable custom components without parsing provider text:
+
+```ts
+type TurnItem =
+  | UserMessage
+  | AssistantMessage
+  | Reasoning
+  | Plan
+  | FileChange
+  | CommandExecution
+  | FileSearch
+  | WebSearch
+  | ApprovalRequest
+  | Checkpoint
+  | Compaction
+  | Handoff
+  | Fork
+  | DynamicTool;
+```
+
+Examples:
+
+```ts
+type FileChange = {
+  type: "file_change";
+  fileName: string;
+  additions?: number;
+  deletions?: number;
+  diffStr?: string;
+  oldStr?: string;
+  newStr?: string;
+};
+
+type CommandExecution = {
+  type: "command_execution";
+  input: string;
+  status: TurnItemStatus;
+  output?: string;
+  exitCode?: number;
+};
+
+type DynamicTool = {
+  type: "dynamic_tool";
+  toolName: string | null;
+  input: unknown;
+  output?: unknown;
+};
+```
+
+Compaction, handoff, and fork are orchestration lifecycle items, not dynamic tools:
+
+- `compaction`: one item can transition from `running` with title like "Compacting context..." to `completed` with title like "Compacted context".
+- `handoff`: records the context bridge from one or more source provider threads/providers to a target provider thread/provider.
+- `fork`: records that the user or system created a new app thread from a run, node, or provider thread.
+
+The UI can render known variants with deterministic components and render `dynamic_tool` as expandable JSON input/output. Each turn item keeps refs back to `runId`, `nodeId`, `providerTurnId`, and `nativeItemRef` so debug views can jump from the display stream back into the graph and provider logs.

+# Entity IDs And Correlation
+
+## Principle
+
+Provider ids are evidence. App ids are identity.
+
+Every durable entity uses an app-owned id as its primary key. Provider-native ids are stored as optional refs and used only for correlation, debugging, replay, and command routing.
+
+## ID Families
+
+```text
+ThreadId              app-visible conversation thread
+RunId                 counted app turn
+NodeId                execution graph node
+ProviderSessionId     live/resumable provider runtime session
+ProviderThreadId      app handle for provider-native conversation
+ProviderTurnId        app handle for provider-native turn
+RuntimeRequestId      app handle for provider callback/request
+RawEventId            optional raw provider diagnostic frame id
+CheckpointId          app checkpoint id
+PlanId                app plan/todo/question artifact id
+```
+
+Provider ids never replace these ids.
+
+## Provider Refs
+
+Provider refs are metadata on runtime entities and events.
+
+```ts
+type ProviderRefs = {
+  provider: ProviderKind;
+  nativeSessionRef?: string;
+  nativeThreadRef?: string;
+  nativeTurnRef?: string;
+  nativeItemRef?: string;
+  nativeRequestRef?: string;
+  rawEventId?: RawEventId;
+  method?: string;
+};
+```
+
+Codex can populate most of these fields. Other providers may populate only a subset.
+
+## Correlation Scope
+
+Correlation is always scoped. Never match a native id globally without a provider/session/thread scope.
+
+Preferred matching keys:
+
+```text
+ProviderThread:
+  provider + providerSessionId + nativeThreadRef
+
+ProviderTurn:
+  providerThreadId + nativeTurnRef
+  or providerThreadId + turnOrdinal
+
+Node / TurnItem:
+  providerTurnId + nativeItemRef
+  or providerTurnId + itemOrdinal
+
+RuntimeRequest:
+  providerSessionId + nativeRequestRef
+  or providerTurnId + requestOrdinal
+```
+
+If a provider recycles ids, the provider adapter must widen the scope until the mapping is unambiguous.
+
+## Mapping Store
+
+V2 needs a durable correlation table or equivalent event-sourced binding stream.
+
+```ts
+type IdentityBinding = {
+  id: IdentityBindingId;
+  appEntityKind: "provider_thread" | "provider_turn" | "node" | "item" | "request" | "message";
+  appEntityId: string;
+  provider: ProviderKind;
+  providerSessionId: ProviderSessionId;
+  nativeKind: string | null;
+  nativeRef: string | null;
+  scope: {
+    threadId: ThreadId | null;
+    runId: RunId | null;
+    parentNodeId: NodeId | null;
+    providerThreadId: ProviderThreadId | null;
+    providerTurnId: ProviderTurnId | null;
+  };
+  correlation: "native_exact" | "native_scoped" | "ordinal" | "fingerprint" | "synthetic";
+  firstRawEventId?: RawEventId;
+  lastRawEventId?: RawEventId;
+  createdAt: string;
+  updatedAt: string;
+};
+```
+
+This is not meant to be a large identity subsystem. It is the minimal durable place that says, "this native thing corresponds to this app thing." Raw event references are optional diagnostic pointers; the binding itself must not require production SQLite to retain raw provider frames forever.
+
+## ID Allocation Rules
+
+1. If the provider gives a stable native id, reuse the existing binding or allocate a new app id and bind it.
+2. If the provider gives no stable id, allocate by scoped ordinal.
+3. If ordinals are insufficient, add a fingerprint inside the scope.
+4. Once allocated, never change the app id for that entity.
+5. Never infer parent/root completion by string matching ids.
+
+## Scoped Ordinals
+
+Weak providers need deterministic ordinals.
+
+```text
+runOrdinalWithinThread
+providerTurnOrdinalWithinProviderThread
+nodeOrdinalWithinParent
+itemOrdinalWithinProviderTurn
+requestOrdinalWithinProviderTurn
+messageOrdinalWithinNode
+```
+
+Ordinals are assigned by the normalizer when provider frames are processed. They must be replay-deterministic for a given provider transcript.
+
+## Fingerprints
+
+Fingerprints are only fallback correlation tools. They should include scope and stable structure, not large mutable text.
+
+Examples:
+
+```text
+ProviderTurn fingerprint:
+  providerThreadId + runId + providerTurnOrdinalWithinProviderThread
+
+Node / TurnItem fingerprint:
+  providerTurnId + itemKind + itemOrdinalWithinProviderTurn + toolName?
+
+RuntimeRequest fingerprint:
+  providerTurnId + requestKind + nativeItemRef? + requestOrdinalWithinProviderTurn
+```
+
+Do not use complete assistant text as a primary fingerprint. Text is mutable, can stream in chunks, and can be duplicated.
+
+## Runtime Events
+
+Normalized runtime events should carry both app ids and provider refs.
+
+```ts
+type RuntimeEvent = {
+  id: RuntimeEventId;
+  type: RuntimeEventType;
+  threadId: ThreadId;
+  runId: RunId | null;
+  nodeId: NodeId | null;
+  parentNodeId: NodeId | null;
+  providerSessionId: ProviderSessionId | null;
+  providerThreadId: ProviderThreadId | null;
+  providerTurnId: ProviderTurnId | null;
+  nativeItemRef: string | null;
+  requestId: RuntimeRequestId | null;
+  providerRefs: ProviderRefs;
+  payload: unknown;
+  createdAt: string;
+};
+```
+
+Downstream systems should use app ids. Provider refs are preserved for inspection and adapter routing.
+
+## Command Routing
+
+UI and orchestration commands target app ids.
+
+```text
+approval.respond(RuntimeRequestId)
+interrupt.run(RunId)
+interrupt.node(NodeId)
+fork.fromNode(NodeId)
+rollback.toRun(ThreadId, runOrdinal)
+```
+
+The provider command layer resolves app ids to provider refs at the edge. If the provider ref is missing or no longer live, the command fails with a typed capability/state error.
+
+Examples:
+
+```text
+RuntimeRequestId -> nativeRequestRef + providerSessionId
+RunId -> root NodeId -> ProviderTurnId -> nativeTurnRef
+NodeId -> ProviderThreadId -> nativeThreadRef
+```
+
+## Pending Requests After Restart
+
+Pending request records may survive restart, but provider callback state usually does not.
+
+V2 should distinguish historical pending-looking requests from respondable requests:
+
+```ts
+type ResponseCapability =
+  | { type: "live"; providerSessionId: ProviderSessionId }
+  | { type: "not_resumable"; reason: string };
+```
+
+The UI can show that a request expired and the user must restart or rerun the turn.
+
+## Subagent Correlation
+
+Subagents are represented through parent-child execution nodes.
+
+For Codex:
+
+```text
+collabAgentToolCall item
+  -> ExecutionNode(kind="subagent" or "tool_call")
+receiverThreadIds[]
+  -> ProviderThread records
+child turn/started and turn/completed
+  -> child ProviderTurn and child ExecutionNode
+```
+
+The child provider turn keeps its own provider refs. It is linked to the parent through `parentNodeId`, not by replacing its turn id with the parent turn id.
+
+For weak providers, the adapter may create a child node by ordinal under the active parent node.
+
+## Replay Determinism
+
+Given the same provider transcript and same initial app state, normalization must produce the same ids.
+
+Requirements:
+
+- Identity bindings are persisted as events or durable rows.
+- Generated ids can be random if the binding is persisted before downstream projection.
+- Fixture replay may use deterministic id generation to make assertions easier.
+- Reprocessing the same provider frame should find the existing binding, not allocate another entity.

+# Feature Lifecycles
+
+This document describes how core user-facing features should work in V2. These flows describe target behavior, not current implementation constraints.
+
+## Creating Threads
+
+Creating an app thread is separate from starting provider work.
+
+```text
+thread.create
+  -> AppThread created
+  -> no provider session required yet
+  -> no provider thread required yet unless eager provider creation is enabled
+```
+
+Provider thread creation may be lazy:
+
+```text
+first run starts
+  -> ensure ProviderSession
+  -> ensure ProviderThread
+  -> send provider turn
+```
+
+If the provider supports empty thread creation, V2 may create a provider thread early. If not, the provider thread is created at first run start.
+
+## Starting A Run
+
+When the user sends a message:
+
+```text
+thread.message.send
+  -> ConversationMessage(role=user)
+  -> Run(status=queued, ordinal=N)
+  -> root ExecutionNode(kind=root_turn, countsForRun=true)
+  -> enqueue provider command
+```
+
+When provider execution begins:
+
+```text
+provider turn accepted/started
+  -> ProviderTurn allocated or correlated
+  -> root node status=running
+  -> run status=running
+```
+
+When the root provider turn completes:
+
+```text
+root provider turn/completed
+  -> finalize assistant streams
+  -> finalize plans/todos/questions
+  -> root node terminal
+  -> capture checkpoint if applicable
+  -> run terminal
+```
+
+Only the root node can complete the run.
+
+## Steering And Queueing Messages
+
+V2 should support three classes of follow-up input:
+
+```text
+steer active run in place
+steer active run by restart
+queue next run
+```
+
+Steering is an app-level intent to change the active run's instructions. Provider-native steering is only one implementation strategy.
+
+If the provider supports active-run steering, the app sends a steer command to the provider and keeps the same run active.
+
+If the provider does not support active-run steering, the app interrupts the active provider turn, finalizes the interrupted attempt, and starts a replacement provider turn for the same app-level steering intent. This may be represented as either:
+
+- the same `RunId` with a new root attempt node, if the UI should treat steering as revising the active run, or
+- a new `RunId` linked by `supersedesRunId`, if preserving the interrupted attempt as a counted turn is important.
+
+The preferred default is the same `RunId` with a new root attempt node until the first attempt has produced a user-meaningful terminal assistant response or checkpoint.
+
+Queueing creates a new run after the active run.
+
+Recommended command shape:
+
+```ts
+type MessageDispatchMode =
+  | { type: "steer_active"; targetRunId: RunId }
+  | { type: "restart_active"; targetRunId: RunId }
+  | { type: "queue_after_active" }
+  | { type: "start_immediately" };
+```
+
+Policy:
+
+- If the provider supports active-run steering, send steer to the provider and attach the message to the active run.
+- If not, interrupt the active provider turn and restart the active run with the steering message included.
+- If the user explicitly requests a new turn, queue even if steering is available.
+- If no run is active, start immediately.
+
+The model supports this because `Run` and `ProviderTurn` are separate. A single app run may have multiple provider-turn attempts when the first attempt was interrupted for steering.
+
+```ts
+type RunAttempt = {
+  id: RunAttemptId;
+  runId: RunId;
+  attemptOrdinal: number;
+  rootNodeId: NodeId;
+  providerThreadId: ProviderThreadId;
+  providerTurnId: ProviderTurnId | null;
+  reason: "initial" | "steering_restart" | "retry" | "provider_recovery";
+  status: "running" | "completed" | "interrupted" | "failed" | "cancelled";
+};
+```
+
+Only the selected/final attempt completes the run and creates the run checkpoint. Earlier interrupted steering attempts remain in the execution graph for audit/debugging.
+
+## Follow-Up Turns
+
+A normal follow-up after a completed run creates a new run.
+
+```text
+previous Run completed
+user sends follow-up
+  -> new Run ordinal=N+1
+  -> new root node
+  -> same AppThread
+  -> same ProviderThread if resumable
+```
+
+If the previous provider thread cannot be resumed due to runtime error, missing native state, or incompatible provider settings, the provider thread is marked unavailable and the app creates a replacement provider thread from reconstructed context.
+
+The replacement path is an error recovery flow, not a provider capability branch.
+
+## Changing Providers Between Runs
+
+Changing providers is a first-class context handoff. It does not fork the app thread and it does not rewrite prior provider history.
+
+```text
+user selects a different provider for next run
+  -> create Run with target provider
+  -> resolve or create target ProviderThread
+  -> create ContextHandoff if target provider thread lacks current app context
+  -> inject handoff summary into provider context
+  -> send user message as the new root turn
+```
+
+Example:
+
+```text
+runs 1-5: Codex provider thread C1
+switch to Claude
+  -> summarize runs 1-5 for Claude
+  -> create Claude provider thread L1
+runs 6-8: Claude provider thread L1
+switch back to Codex
+  -> resume Codex provider thread C1 if possible
+  -> summarize runs 6-8 for Codex
+  -> send run 9 to C1 with the delta handoff
+```
+
+The default policy when returning to a provider is to resume the previous provider thread and bridge only the off-provider delta. This preserves native continuity for that provider's own earlier work while informing it about what happened elsewhere.
+
+Fallback policy: create a fresh provider thread with a full app-thread summary when:
+
+- the previous provider thread cannot be resumed,
+- the provider's context is likely too stale or polluted by repeated handoffs,
+- model/runtime settings changed incompatibly,
+- the user explicitly requests a clean provider context.
+
+The fallback should be explicit in the graph:
+
+```text
+new ProviderThread
+  forked/reconstructed from AppThread summary
+  ContextHandoff(strategy=full_thread_summary)
+```
+
+Provider switching should never concatenate hidden summaries into arbitrary prompts without recording the handoff. The handoff text is part of the run input contract and must be auditable.
+
+## Forking Threads
+
+Forking creates a new app thread from a source point. It should not require provider selection and it should not eagerly create provider runtime state.
+
+```text
+thread.fork
+  -> create target AppThread
+  -> record AppThread lineage
+  -> create ContextTransfer(type=fork, status=pending)
+  -> no ProviderSession required
+  -> no ProviderThread required
+  -> no portable context handoff required
+```
+
+The first run on the fork resolves the pending transfer:
+
+```text
+first message on fork selects provider P
+  -> if source provider is P and native fork is available:
+       resolve by provider-native fork
+     else:
+       materialize portable context
+  -> create/resume target ProviderThread
+  -> send resolved context + user message
+```
+
+The preferred first implementation should fork only from stable source points: completed runs, checkpoints, or idle provider threads with known coverage. Forking from an active run should use the latest completed checkpoint or be rejected until active-run semantics are deliberately designed.
+
+## Merge-Back From Forks
+
+Merge-back brings fork exploration into a source thread without copying the entire fork transcript into the main provider context.
+
+```text
+source thread forked at point S
+fork thread explores through point F
+user sends next source-thread message with merge-back intent
+  -> create ContextTransfer(type=merge_back, basePoint=S, sourcePoint=F)
+  -> build delta context lazily
+  -> inject delta with the next source-thread user message
+```
+
+The delta should describe what changed since the fork point: decisions, files changed, commands/tests run, conclusions, and unresolved issues. It should not include provider protocol noise or full transcript content unless needed.
+
+## Interruption
+
+Interruption targets a run or a node.
+
+```text
+interrupt.run(RunId)
+  -> resolve root node
+  -> resolve provider turn/thread refs
+  -> provider interrupt command if supported
+  -> mark interrupt requested
+```
+
+Terminal state arrives from provider lifecycle:
+
+```text
+provider interrupt request returns
+  -> command acknowledged only
+provider emits root turn/completed status=interrupted
+  -> root node interrupted
+  -> run interrupted
+  -> checkpoint policy runs
+```
+
+The app should not mark the run terminal solely because the interrupt request returned.
+
+If the provider does not support interruption:
+
+- best case: stop provider session and mark run interrupted or cancelled by policy.
+- worst case: mark interrupt unsupported and leave run active until provider exits.
+
+## Resumption
+
+Resumption has three related meanings:
+
+1. Resume an app thread in the UI from persisted projection.
+2. Resume a provider-native conversation/session.
+3. Recover or recreate a live provider runtime process while preserving app and provider-thread continuity.
+
+V2 always supports app-thread resumption from stored events/projections. Provider-thread resumption is a required provider adapter primitive. Every provider harness must expose a cursor/session/thread handle that can be used to resume prior provider state.
+
+Provider runtime recovery is also a core primitive, not a test-only hook. The same recovery path is used when:
+
+- the user restarts the app/server and all provider processes are gone,
+- an idle-session reaper intentionally releases provider processes,
+- a provider process crashes or loses network and policy allows retry.
+
+```text
+open app thread
+  -> load AppThread, Runs, Messages, ExecutionGraph summary
+  -> if provider work must continue, resume the relevant ProviderThread
+```
+
+Provider resume flow:
+
+```text
+resolve activeProviderThreadId
+resolve nativeThreadRef / nativeConversationHeadRef resume cursor
+start ProviderSession
+provider resume
+bind new ProviderSessionId to ProviderThread
+```
+
+Provider runtime recovery flow:
+
+```text
+provider runtime unavailable
+  -> mark ProviderSession stopped/error with reason
+  -> remove live runtime handle from ProviderSessionManager
+  -> keep ProviderThread and nativeThreadRef durable
+  -> on next work, open a new provider runtime
+  -> resume the active ProviderThread before starting/retrying work
+```
+
+Idle cleanup and crash recovery must use production lifecycle APIs. Tests may recreate the outermost layer/runtime or drive the same reaper/recovery service with deterministic clock and replayed provider transport, but they must not use test-only session restart methods.
+
+If provider resume fails:
+
+- preserve historical graph.
+- mark provider thread not loaded or error.
+- create replacement provider thread from reconstructed app context when the user continues.
+- mark pending live requests as not resumable.
+
+Provider resume failure is a runtime/recovery condition. It should not be modeled as "provider does not support resume."
+
+## Forking
+
+Forking creates a new first-class `AppThread` from a stable source.
+
+Supported fork sources:
+
+```ts
+type ForkSource =
+  | { type: "run"; threadId: ThreadId; runId: RunId }
+  | { type: "node"; nodeId: NodeId }
+  | {
+      type: "provider_thread";
+      providerThreadId: ProviderThreadId;
+      providerTurnId?: ProviderTurnId;
+    };
+```
+
+Stable fork boundaries:
+
+- completed run
+- interrupted or failed run with a provider snapshot/checkpoint
+- completed subagent node with a provider thread
+- provider thread snapshot returned by the provider
+- checkpoint boundary
+
+Unstable boundaries:
+
+- streaming message delta
+- active tool call
+- pending approval
+- active subagent turn, unless live fork support is explicitly implemented
+
+Forking from a subagent:
+
+```text
+subagent node selected
+  -> resolve ProviderThread owned by node
+  -> provider fork/resume if supported
+  -> create new AppThread
+  -> attach forked ProviderThread
+  -> copy/link checkpoint baseline
+```
+
+If the provider cannot fork native threads, V2 may synthesize a fork by creating a new app thread with projected messages/context, but that should be marked as lower fidelity by capability.
+
+## Checkpointing
+
+Checkpoints attach to checkpoint scopes. Root runs and child execution nodes can both be checkpointed.
+
+Pre-run baseline:
+
+```text
+before root execution starts
+  -> ensure root checkpoint for current app run ordinal - 1
+```
+
+Post-root-run checkpoint:
+
+```text
+root node terminal
+  -> drain/finalize streams
+  -> capture root checkpoint for app run ordinal
+  -> compute diff from prior root checkpoint
+  -> mark run terminal with checkpoint
+```
+
+Child/subagent checkpoint:
+
+```text
+child checkpointable node starts
+  -> create child CheckpointScope under parent scope
+child node terminal
+  -> drain/finalize child streams/items
+  -> capture child checkpoint for that scope
+  -> compute diff from parent/previous child checkpoint
+  -> mark child node checkpointed
+```
+
+Interrupted/failed runs:
+
+- If filesystem state is meaningful and safe to capture, capture with status reflecting terminal state.
+- If not, store a missing/error checkpoint summary.
+- Child/subagent checkpoints are allowed, but they do not advance the parent app run count.
+- Root run checkpointing should include or reference child checkpoint summaries so the run has a complete audit trail.
+
+Rollback:
+
+```text
+rollback.toRun(threadId, targetRunOrdinal)
+  -> restore filesystem checkpoint targetRunOrdinal
+  -> compute provider turns to roll back if provider supports rollback
+  -> call provider rollback
+  -> reconcile returned provider snapshot if available
+  -> mark later runs rolled_back
+  -> delete or mark stale later checkpoint refs
+```
+
+Codex `thread/rollback` returns an authoritative provider thread snapshot. Other providers may require a synthetic provider thread restart from context.
+
+Nested rollback:
+
+```text
+rollback.node(nodeId, checkpointId)
+  -> restore child checkpoint if scope cwd/ref is available
+  -> roll back provider thread for that child scope if supported
+  -> mark descendant child checkpoints stale/rolled_back
+  -> preserve parent run checkpoint history unless parent filesystem state changed
+```
+
+If a child checkpoint mutates the same workspace as the parent, restoring it may dirty the parent run's workspace state. The UI/API should make that explicit.
+
+## Approvals
+
+Approvals are runtime requests scoped to execution nodes.
+
+```text
+provider requestApproval
+  -> RuntimeRequest(kind=...)
+  -> approval ExecutionNode
+  -> thread pending request projection
+  -> optional thread status waiting
+```
+
+User response:
+
+```text
+approval.respond(RuntimeRequestId)
+  -> resolve live provider callback
+  -> send provider response
+  -> RuntimeRequest resolved
+  -> approval node completed/cancelled
+```
+
+Rules:
+
+- Approval ids are app-owned.
+- Provider request ids are refs.
+- Pending approvals from subagents are still actionable if the provider exposes live response capability.
+- Approval response should fail with `not_resumable` if provider callback state is gone.
+
+## Ask Questions / User Input
+
+Ask-questions is a user-input request, not a plan by itself.
+
+```text
+provider requests user input
+  -> RuntimeRequest(kind=user_input)
+  -> ExecutionNode(kind=user_input_request)
+  -> Question artifact
+  -> run status=waiting
+```
+
+On answer:
+
+```text
+user-input.respond(RuntimeRequestId, answers)
+  -> provider callback
+  -> request resolved
+  -> node completed
+  -> run resumes/runs
+```
+
+If the provider does not support structured questions, the adapter may project a plain assistant message and no respondable request.
+
+## Plans And Todo Lists
+
+V2 separates three concepts:
+
+- Proposed plan: a durable plan artifact the user can accept/implement.
+- Todo list: live execution progress for the current run.
+- Ask questions: structured user-input request.
+
+Codex examples:
+
+```text
+turn/plan/updated
+  -> PlanArtifact(kind=todo_list)
+  -> activity/projection update
+
+item/plan/delta or plan item completed
+  -> PlanArtifact(kind=proposed_plan)
+
+item/tool/requestUserInput
+  -> PlanArtifact(kind=questions)
+  -> RuntimeRequest(kind=user_input)
+```
+
+Rules:
+
+- Root run todo lists update the main plan/progress UI.
+- Child/subagent todo lists are nested under their execution node.
+- Child plans do not replace root plans unless promoted/forked.
+- Proposed plan implementation creates a new run or a new thread depending on user action.
+
+## Activities
+
+Activities are a projection of execution graph events.
+
+Examples:
+
+```text
+tool.started
+approval.requested
+approval.resolved
+plan.updated
+checkpoint.captured
+subagent.started
+subagent.completed
+runtime.warning
+```
+
+Activities should keep `nodeId` and `runId` so the UI can group them correctly.
+
+## Completion Barriers
+
+Before a run is marked terminal, V2 should pass a finalization barrier:
+
+```text
+root provider turn terminal
+  -> flush assistant text buffers
+  -> close active assistant messages
+  -> finalize plan/todo artifacts
+  -> close open non-live child nodes if provider marked them done
+  -> capture checkpoint
+  -> publish run terminal
+```
+
+This prevents early checkpoint capture and incomplete plan state.

+# Orchestrator MCP Server
+
+## Purpose
+
+T3 exposes V2 orchestration through its app-owned MCP endpoint. A provider
+agent can use this endpoint to:
+
+- create an app-owned sub-agent on any supported provider instance;
+- wait for or poll the sub-agent's durable result;
+- cancel an active delegated task; and
+- create one or more ordinary top-level T3 threads;
+- list and incrementally read project threads;
+- send or steer follow-up messages; and
+- wait for or interrupt ordinary thread runs.
+
+These are T3 orchestration operations, not provider-native sub-agent APIs.
+Delegated tasks always create a T3 child thread and run. The child receives
+only the supplied task prompt, plus an optional role instruction supplied in
+the same tool call. Parent conversation history is not copied into the child.
+
+`ThreadManagementService` is the shared server application boundary for V2
+WebSocket commands and MCP. It owns project-scoped lookup, listing, send-mode
+selection, durable send postconditions, wait polling, and interrupt selection;
+`OrchestratorV2` remains the lower-level command/event processor. Transport
+adapters only authenticate, resolve transport-specific inputs, and shape
+responses.
+
+## Transport And Authentication
+
+The orchestration tools share the existing authenticated HTTP MCP endpoint:
+
+```text
+http://127.0.0.1:<server-port>/mcp
+```
+
+The provider-visible server key is `t3-code`. The endpoint registers both the
+preview toolkit and the orchestration toolkit.
+
+Before `ProviderSessionManager` opens a new V2 provider session, it asks
+`McpSessionRegistry` for a credential scoped to:
+
+- the T3 environment;
+- the parent T3 thread;
+- the concrete provider instance; and
+- the provider session.
+
+The credential grants `preview` and `orchestration` capabilities. Credentials
+expire after a maximum lifetime, expire when idle, and are revoked when the
+provider session is released. The raw token is not persisted in orchestration
+state.
+
+The MCP HTTP server resolves the bearer token and supplies the resulting
+`McpInvocationScope` to tool handlers. Orchestration handlers additionally
+check the `orchestration` capability before reading or mutating state.
+
+## Provider Injection
+
+### Codex V2
+
+Codex app-server receives the remote MCP server through command-line config
+overrides:
+
+```text
+-c mcp_servers.t3-code.url=http://127.0.0.1:<port>/mcp
+-c mcp_servers.t3-code.bearer_token_env_var="T3_MCP_BEARER_TOKEN"
+```
+
+The provider-session token is placed in `T3_MCP_BEARER_TOKEN`. Both the
+production Codex launcher and the injectable test launcher use the same
+projection helper.
+
+### Claude Agent SDK V2
+
+Claude receives an HTTP MCP server in its query options:
+
+```ts
+{
+  mcpServers: {
+    "t3-code": {
+      type: "http",
+      url: "http://127.0.0.1:<port>/mcp",
+      headers: {
+        Authorization: "Bearer <provider-session-token>",
+      },
+    },
+  },
+  allowedTools: [
+    // existing allowed tools
+    "mcp__t3-code__*",
+  ],
+}
+```
+
+The adapter logs only whether MCP configuration exists; it does not log the
+server headers or token.
+
+### Cursor Agent SDK V2
+
+Cursor receives the same authenticated HTTP MCP endpoint through the SDK's
+`mcpServers` agent and send options. The adapter passes the authorization header
+to the SDK but projects only redacted option metadata into protocol diagnostics.
+
+### Grok ACP V2
+
+Grok receives the authenticated HTTP MCP endpoint through the ACP
+`session/new`, `session/load`, and `session/fork` `mcpServers` field. The shared
+ACP adapter owns standard protocol behavior; the Grok flavor adds xAI extension
+requests such as structured user questions.
+
+ACP does not define native subagents or active steering. Grok therefore uses
+orchestrator-owned child threads and implements steering through
+cancel-and-restart. Its current driver also lacks `session/fork`, so app forks
+use portable context transfer. These are orchestrator policies, not
+provider-specific MCP tools.
+
+### ACP Registry V2
+
+The `acpRegistry` driver is the generic flavor of the same shared ACP adapter.
+Each provider instance names an agent from the official ACP Registry. At
+session startup the driver resolves the current platform distribution, uses a
+managed binary cache or the declared `npx`/`uvx` package, and then negotiates
+standard ACP capabilities during `initialize`. A local executable may override
+the managed command without changing the registry-declared arguments or
+environment.
+
+Capabilities such as session loading, session forking, models, modes, and MCP
+transport are enabled only when the selected agent advertises them. Missing
+features degrade through V2 policy: steering uses interrupt-and-restart,
+forking uses portable context when native `session/fork` is unavailable, and
+subagents use orchestrator-owned child threads. Registry agents do not receive
+provider-specific extensions; those remain in flavors such as Grok.
+
+### Initial Provider Support
+
+The V2 provider adapters are Codex, Claude Agent SDK, Cursor Agent SDK, and
+Grok plus generic registry agents over ACP.
+Capability discovery still reports other registered provider instances, but marks them
+unavailable for orchestration when no V2 adapter exists. This keeps provider
+selection model-visible without allowing a request that cannot run.
+
+## Tool Surface
+
+The server exposes eleven orchestration tools.
+
+### `orchestrator_capabilities`
+
+Returns:
+
+- the inherited provider instance and model;
+- the parent runtime and interaction modes;
+- registered provider instances and advertised models;
+- whether each provider can run a child task; and
+- feature flags for polling, cancellation, and batch thread creation.
+
+Unavailable providers include model-visible constraints such as missing V2
+adapter support, disabled state, missing executable, or missing authentication.
+
+### `delegate_task`
+
+Creates a T3-owned child thread and immediately dispatches the supplied task
+prompt.
+
+```ts
+type DelegateTaskInput = {
+  task: string;
+  target?: {
+    providerInstanceId?: string;
+    driverKind?: string;
+    model?: string;
+  };
+  title?: string;
+  role?: "implementation" | "research" | "review" | "design" | "test" | "general";
+  mode?: "async" | "wait";
+  timeoutMs?: number;
+  clientRequestId?: string;
+  runtimeMode?: "inherit" | "approval-required" | "auto-accept-edits" | "full-access";
+  interactionMode?: "inherit" | "plan" | "default";
+};
+```
+
+Provider, model, runtime mode, and interaction mode inherit from the parent
+when omitted. Selecting a different provider without a model uses that
+provider's first advertised model.
+
+Delegation requires an active parent run owned by the MCP credential's
+provider session. The request becomes the V2 command
+`delegated_task.request`.
+
+`mode: "async"` returns the current durable state immediately.
+`mode: "wait"` polls the original delegated run until it becomes terminal or
+the timeout expires. A wait timeout does not cancel the child; the result sets
+`waitTimedOut: true`, and the caller can continue with `task_status`.
+
+```ts
+type DelegateTaskResult = {
+  taskId: string;
+  childThreadId: string;
+  childRunId: string | null;
+  childNodeId: string;
+  status: "queued" | "running" | "waiting" | "completed" | "failed" | "cancelled" | "interrupted";
+  hasPendingChildRuns: boolean;
+  providerInstanceId: string;
+  model: string | null;
+  summary: string | null;
+  resultContextTransferId: string | null;
+  latestTerminalRunId: string | null;
+  latestTerminalStatus: "completed" | "failed" | "cancelled" | "interrupted" | null;
+  latestTerminalSummary: string | null;
+  latestTerminalResultContextTransferId: string | null;
+  waitTimedOut: boolean;
+};
+```
+
+### `task_status`
+
+Reads a delegated task from the parent thread's durable projection. A task ID
+from another parent thread is rejected. The primary `childRunId`, `status`,
+`summary`, and `resultContextTransferId` fields stay tied to the original
+delegated run. `hasPendingChildRuns` remains true while any later child run is
+queued or executing. The `latestTerminal*` fields expose the original run or
+the highest-ordinal later terminal run that began execution. Rolled-back runs
+and never-started later cancellations do not displace the latest meaningful
+result.
+
+### `task_cancel`
+
+Interrupts the original delegated run through the normal V2 `run.interrupt`
+command. It is idempotent for terminal tasks and accepts an optional cancellation
+reason. Use `t3_thread_interrupt` to interrupt a later follow-up run.
+
+### `create_threads`
+
+Creates between one and twenty ordinary top-level T3 threads:
+
+```ts
+type CreateThreadsInput = {
+  threads: Array<{
+    prompt?: string;
+    title?: string;
+    target?: {
+      providerInstanceId?: string;
+      driverKind?: string;
+      model?: string;
+    };
+    runtimeMode?: "inherit" | "approval-required" | "auto-accept-edits" | "full-access";
+    interactionMode?: "inherit" | "plan" | "default";
+  }>;
+  clientRequestId?: string;
+};
+```
+
+Each entry independently resolves provider, model, and modes. The new threads
+inherit the parent's project, branch, and worktree path, but they have no
+sub-agent lineage. Entries with a prompt immediately dispatch a run; entries
+without a prompt remain idle.
+
+### `t3_thread_start`
+
+Creates one ordinary top-level thread and immediately dispatches its first
+prompt. It is the single-thread convenience form of `create_threads` and
+returns the created thread and run IDs. Use `clientRequestId` when a caller may
+retry the request.
+
+### `t3_thread_list`
+
+Lists durable thread shells in the calling thread's project, newest first.
+Callers can filter by title, run status, and whether app-owned sub-agent threads
+are included. Results are bounded and offset-paginated. Deleted threads and
+threads from other projects are never exposed.
+
+### `t3_thread_read`
+
+Reads a project-scoped thread's durable state, recent runs, and visible
+timeline. The default `messages` view returns user messages, assistant
+messages, and proposed plans. The `activity` view also returns summarized tool,
+reasoning, checkpoint, handoff, and runtime-request items. Large item text is
+bounded and reports whether it was truncated. `afterPosition` and
+`nextPosition` support incremental reads.
+
+Thread and message results include required `createdBy` and `creationSource`
+provenance. MCP-created threads and user-role messages use `createdBy: "agent"`
+and `creationSource: "mcp"`; provider output uses `creationSource: "provider"`.
+Actor and ingress are separate so agent-authored user-role messages remain
+distinguishable from human-authored messages.
+
+### `t3_thread_send`
+
+Sends a message to an ordinary or delegated thread in the calling project:
+
+- `auto` starts an idle thread, steers a fully active turn, or queues behind a
+  turn that is not yet steerable;
+- `queue` creates a separate follow-up run after active work;
+- `steer` requires a steerable active provider turn; and
+- `restart` requires an active provider turn and uses the orchestrator's
+  interrupt-and-restart path.
+
+The target runtime and interaction modes may not be broader than the caller's.
+Stable command and message IDs are derived from `clientRequestId` for
+idempotent retries.
+
+### `t3_thread_wait`
+
+Waits for a selected run to become `completed`, `failed`, `cancelled`,
+`interrupted`, or `rolled_back`. Without `runId`, it pins the latest run at call
+time; an idle thread returns immediately. A timeout reports the latest durable
+status and does not cancel work.
+
+### `t3_thread_interrupt`
+
+Interrupts a selected active run through the normal V2 `run.interrupt` command.
+Without `runId`, it selects the newest interruptible run. A terminal run is
+returned unchanged, and a thread with no active provider turn returns
+`no_active_run`.
+
+## Delegated Task Lifecycle
+
+The MCP server is a command ingress into V2. It does not call provider adapters
+directly.
+
+```text
+provider model
+  -> MCP tools/call delegate_task
+  -> authenticated OrchestratorMcpService
+  -> shared ThreadManagementService
+  -> V2 delegated_task.request command
+  -> child thread + child run
+  -> parent app_owned subagent projection
+  -> parent/child execution nodes
+  -> consumed subagent_spawn context transfer
+  -> normal provider effect and runtime ingestion
+  -> child run reaches a terminal state
+  -> parent subagent/node/turn item finalized
+  -> consumed subagent_result context transfer
+  -> wait result or later task_status result
+```
+
+The child thread has lineage relationship `subagent` and points back to the
+parent node. The parent gets an `app_owned` sub-agent projection and a
+sub-agent turn item so the existing debug UI can render progress.
+
+Terminal provider events trigger finalization. The event stream first replays
+persisted events and then follows live events, so finalization also runs after
+a server restart. An existing `subagent_result` transfer makes finalization
+idempotent.
+
+The result summary prefers the latest assistant content from the child run and
+falls back to a terminal-status message when no assistant text exists.
+
+## Policy And Idempotency
+
+- A child runtime mode may stay equal to or become narrower than the parent
+  mode. It may not escalate privileges.
+- A child interaction mode may stay equal to or narrow from `default` to
+  `plan`. It may not escalate from `plan` to `default`.
+- General thread management is limited to the calling thread's project. Send
+  additionally enforces the same runtime and interaction privilege ceiling as
+  child creation.
+- Provider instances must be enabled, installed, available, authenticated, and
+  backed by a V2 adapter.
+- A requested model must be advertised by the selected provider when the
+  provider publishes a model list.
+- `clientRequestId` derives stable command, thread, and message IDs within the
+  provider session. Retrying the same call returns the same durable work.
+- Calls without `clientRequestId` receive a generated request key and create
+  new work.
+
+Expected denials use the typed `OrchestratorMcpFailure` result:
+
+```text
+capability_denied
+parent_not_active
+provider_unavailable
+model_unavailable
+runtime_mode_escalation_denied
+interaction_mode_escalation_denied

+thread_not_found
+run_not_found
+thread_not_sendable

+
+## Code Ownership
+
+- Shared schemas: `packages/contracts/src/orchestratorMcp.ts`
+- MCP service: `apps/server/src/mcp/OrchestratorMcpService.ts`
+- Tool definitions and handlers:
+  `apps/server/src/mcp/toolkits/orchestrator/`
+- HTTP registration and authentication:

+
+## Verification
+
+The integration test uses the real MCP toolkit registration, V2 orchestrator,
+SQL persistence, event ingestion, projections, and checkpoints. Only the
+external provider adapters are deterministic test implementations.
+
+Coverage includes:
+
+- capability discovery;
+- cross-provider delegated completion;
+- prompt-only child context;
+- parent and child lineage projections;
+- spawn and result context transfers;
+- async status polling;
+- cancellation;
+- batch ordinary-thread creation;
+- project-scoped thread listing and timeline reads;
+- ordinary-thread send, wait, steering, and interruption;
+- inheritance and per-thread provider overrides; and
+- idempotent retries.
+
+Provider adapter tests separately verify Codex, Claude, Cursor, Grok, and ACP
+Registry behavior and MCP injection. The provider-session manager test verifies
+that credentials exist before an adapter opens and are revoked when it closes.

+# Provider Capability System
+
+V2 must not assume every provider can do what Codex can do. Provider behavior should be expressed through capabilities and policies, not provider-name conditionals spread across orchestration.
+
+## Capability Shape
+
+```ts
+type ProviderCapabilities = {
+  sessions: SessionCapabilities;
+  threads: ThreadCapabilities;
+  turns: TurnCapabilities;
+  streaming: StreamingCapabilities;
+  tools: ToolCapabilities;
+  approvals: ApprovalCapabilities;
+  planning: PlanningCapabilities;
+  subagents: SubagentCapabilities;
+  context: ContextCapabilities;
+  checkpointing: CheckpointCapabilities;
+  identity: IdentityCapabilities;
+};
+```
+
+Capabilities should be versioned and emitted by each adapter at session start.
+
+## Session Capabilities
+
+```ts
+type SessionCapabilities = {
+  supportsMultipleProviderThreadsPerSession: boolean;
+  supportsModelSwitchInSession: boolean;
+  supportsProviderSwitchingViaHandoff: boolean;
+  supportsRuntimeModeSwitchInSession: boolean;
+  pendingRequestsSurviveRestart: boolean;
+};
+```
+
+Policy examples:
+
+- If model switching is unsupported, start a new provider session.
+- If pending requests do not survive restart, mark old requests `not_resumable`.
+
+Provider-thread resumption is not a capability. It is a required adapter primitive. Adapters must be able to start from a stored provider cursor/session/thread handle or return a runtime resume failure.
+
+## Thread Capabilities
+
+```ts
+type ThreadCapabilities = {
+  canCreateEmptyThread: boolean;
+  canReadThreadSnapshot: boolean;
+  canRollbackThread: boolean;
+  canForkThread: boolean;
+  canForkFromTurn: boolean;
+  canForkFromSubagentThread: boolean;
+  exposesNativeThreadId: boolean;
+};
+```
+
+Codex can expose strong thread ids and rollback snapshots. Claude may support native forking through its own model/session primitives. Other providers may only support synthetic app forks.
+
+## Turn Capabilities
+
+```ts
+type TurnCapabilities = {
+  exposesNativeTurnId: boolean;
+  emitsTurnStarted: boolean;
+  emitsTurnCompleted: boolean;
+  supportsInterrupt: boolean;
+  supportsActiveSteering: boolean;
+  supportsSteeringByInterruptRestart: boolean;
+  supportsQueuedMessages: boolean;
+  terminalStatusQuality: "strong" | "weak" | "none";
+};
+```
+
+If `terminalStatusQuality` is weak, V2 should use adapter policy to infer terminal state, but still mark correlation strength accordingly.
+
+`supportsActiveSteering` means the provider can modify an in-flight turn directly. `supportsSteeringByInterruptRestart` means V2 can implement app-level steering by interrupting the active turn and starting a replacement attempt. Most providers should support the latter if they support interruption and normal follow-up turns.
+
+## Streaming Capabilities
+
+```ts
+type StreamingCapabilities = {
+  streamsAssistantText: boolean;
+  streamsReasoning: boolean;
+  streamsToolOutput: boolean;
+  streamsPlanText: boolean;
+  emitsMessageCompleted: boolean;
+};
+```
+
+If message completion is not emitted, the normalizer closes assistant messages at root run terminal.
+
+## Tool Capabilities
+
+```ts
+type ToolCapabilities = {
+  exposesToolItemIds: boolean;
+  emitsToolStarted: boolean;
+  emitsToolCompleted: boolean;
+  emitsToolOutput: boolean;
+  supportsMcpTools: boolean;
+  supportsDynamicToolCallbacks: boolean;
+};
+```
+
+Weak providers may produce only textual tool summaries. The adapter can still create ordered `turnItems` and execution nodes by scoped ordinal.
+
+## Approval Capabilities
+
+```ts
+type ApprovalCapabilities = {
+  supportsCommandApproval: boolean;
+  supportsFileReadApproval: boolean;
+  supportsFileChangeApproval: boolean;
+  supportsApplyPatchApproval: boolean;
+  approvalsHaveNativeRequestIds: boolean;
+  approvalCallbacksAreLiveOnly: boolean;
+  approvalsCanOriginateFromSubagents: boolean;
+};
+```
+
+The UI should show pending approvals from any execution node, including subagents, if they are respondable.
+
+## Planning Capabilities
+
+```ts
+type PlanningCapabilities = {
+  emitsPlanUpdated: boolean;
+  emitsTodoList: boolean;
+  emitsProposedPlan: boolean;
+  supportsStructuredQuestions: boolean;
+  planDeltasHaveItemIds: boolean;
+};
+```
+
+Mapping policy:
+
+- `emitsTodoList`: update live run progress.
+- `emitsProposedPlan`: create accept/implementable plan artifacts.
+- `supportsStructuredQuestions`: create respondable user-input requests.
+
+If a provider only emits plain assistant text, the app should not pretend it has structured plans.
+
+## Subagent Capabilities
+
+```ts
+type SubagentCapabilities = {
+  supportsSubagents: boolean;
+  exposesSubagentThreadIds: boolean;
+  emitsSubagentLifecycle: boolean;
+  canWaitForSubagents: boolean;
+  canCloseSubagents: boolean;
+  canForkSubagentThread: boolean;
+};
+```
+
+When `exposesSubagentThreadIds` is true, subagent provider threads become addressable `ProviderThread` records. When false, subagents can still be shown as nested execution nodes if the provider exposes enough lifecycle information.
+
+## Context Handoff Capabilities
+
+Context handoff controls provider switching and provider-thread reconstruction.
+
+```ts
+type ContextCapabilities = {
+  acceptsSystemContext: boolean;
+  acceptsDeveloperContext: boolean;
+  acceptsSyntheticUserContext: boolean;
+  canGenerateSummaries: boolean;
+  canConsumeHandoffSummaries: boolean;
+  supportsDeltaHandoff: boolean;
+  supportsFullThreadHandoff: boolean;
+  maxRecommendedHandoffChars: number | null;
+};
+```
+
+Policy examples:
+
+- If `supportsDeltaHandoff` is available, return to a previous provider thread with a summary of only off-provider runs.
+- If delta handoff is unsupported or low quality, create a new provider thread with a full thread summary.
+- If the provider cannot accept explicit context, provider switching should require synthetic user context or be marked unsupported.
+- If no provider can generate summaries, use the app's configured summarization provider or a local summarizer capability.
+
+## Checkpoint Capabilities
+
+Checkpointing is primarily app-owned, but provider conversation rollback is provider-dependent.
+
+```ts
+type CheckpointCapabilities = {
+  appCanCheckpointFilesystem: boolean;
+  supportsNestedCheckpointScopes: boolean;
+  providerCanRollbackConversation: boolean;
+  providerRollbackReturnsSnapshot: boolean;
+  providerCanReadConversationSnapshot: boolean;
+};
+```
+
+If provider rollback is unsupported, filesystem rollback can still happen, but provider conversation state must be restarted or marked divergent. Nested checkpoint scopes are app-owned; providers only affect whether their nested provider conversations can be rolled back to match restored filesystem state.
+
+## Identity Capabilities
+
+```ts
+type IdentityCapabilities = {
+  nativeThreadIds: "strong" | "weak" | "none";
+  nativeTurnIds: "strong" | "weak" | "none";
+  nativeItemIds: "strong" | "weak" | "none";
+  nativeRequestIds: "strong" | "weak" | "none";
+};
+```
+
+This controls how the normalizer correlates events:
+
+- `strong`: use native id as scoped provider ref.
+- `weak`: use native id plus ordinal/fingerprint.
+- `none`: allocate by scoped ordinal.
+
+## Degradation Policies
+
+Every feature should declare what happens when capability is missing.
+
+Examples:
+
+```text
+interrupt unsupported
+  -> stop session if allowed, otherwise mark unsupported
+
+active steering unsupported
+  -> interrupt active turn and restart the run as a steering replacement attempt
+
+fork unsupported
+  -> synthetic fork from app projection if policy allows
+
+rollback unsupported
+  -> restore filesystem checkpoint, restart provider context, mark provider state divergent
+
+nested checkpoint unsupported
+  -> capture only root-run checkpoint and record child filesystem activity as uncheckpointed
+
+provider switch return unsupported
+  -> create fresh provider thread with full app-thread summary
+
+structured approvals unsupported
+  -> provider runs under configured sandbox policy; no approval UI
+
+plan_updated unsupported
+  -> no live todo UI; rely on assistant messages
+```
+
+The UI should not hide unsupported behavior behind provider-specific errors. It should receive typed capability results.
+
+## Adapter Contract
+
+Each provider adapter should expose:
+
+```ts
+type ProviderAdapter = {
+  getCapabilities(): ProviderCapabilities;
+  startSession(input): ProviderSession;
+  ensureProviderThread(input): ProviderThread;
+  sendRun(input): ProviderTurnStartResult;
+  steerRun?(input): void;
+  interrupt(input): void;
+  respondToRequest(input): void;
+  readThreadSnapshot?(input): ProviderThreadSnapshot;
+  rollbackThread?(input): ProviderThreadSnapshot | void;
+  forkThread?(input): ProviderThread;
+  streamEvents(): Stream<ProviderAdapterEvent>;
+};
+```
+
+Optional methods are guarded by capabilities. The orchestration layer should not call optional methods without checking capability or going through a policy wrapper.
+
+Raw provider frames should be logged by the provider transport/runtime as bounded diagnostics. Adapter streams should expose normalized provider events that the V2 normalizer can turn into app orchestration events.
+
+## Capability-Driven UI
+
+The UI should receive capability-informed affordances:
+
+- show or hide fork action by fork source.
+- show interrupt as available, destructive fallback, or unavailable.
+- show approvals as respondable or expired.
+- show plan/todo panels only when structured plan artifacts exist.
+- show rollback only when app checkpoint exists, and annotate provider rollback support.
+
+This keeps the product predictable across Codex, Claude, Cursor, OpenCode, and future providers.

+# Provider Switching And Context Handoff
+
+Provider switching is a first-class V2 feature. An app thread may contain runs from multiple providers while preserving each provider's native conversation handles and the app's canonical conversation history.
+
+This document describes the provider-switching specialization of the broader [Thread Lineage And Context Transfer](./thread-lineage-and-context-transfer.md) model. Provider switching is a context transfer where the source and target app thread are usually the same thread. Forking, merge-back, and subagents use the same source-point/resolution concepts with different product lifecycles.
+
+## Recommendation
+
+When returning to a provider that was used earlier, default to resuming that provider's previous provider thread and inject a delta summary covering the runs that happened while the provider was inactive.
+
+Create a fresh provider thread with a full app-thread summary only when resuming the prior provider thread fails, settings are incompatible, or delta handoff is likely to produce poor context.
+
+This gives the best default tradeoff:
+
+- preserves native continuity for provider-specific prior work,
+- avoids repeatedly summarizing everything,
+- lets each provider keep its own tool/history affordances,
+- makes cross-provider context explicit and auditable,
+- keeps a clean fallback when old provider context is stale.
+
+## Example
+
+```text
+runs 1-5: Codex, ProviderThread C1
+switch to Claude for run 6
+  -> ContextHandoff H1 covers runs 1-5
+  -> create ProviderThread L1
+  -> run 6 uses L1 with H1
+runs 6-8: Claude, ProviderThread L1
+switch back to Codex for run 9
+  -> ContextHandoff H2 covers runs 6-8
+  -> resume ProviderThread C1
+  -> run 9 uses C1 with H2
+```
+
+ProviderThread C1 is not expected to natively contain Claude's runs. It contains Codex's native conversation plus explicit handoff artifacts that summarize external progress.
+
+## Why Not Always Create A Fresh Provider Thread?
+
+Always creating a fresh provider thread is simpler but loses useful provider-native continuity:
+
+- prior hidden reasoning/context that is only available in the provider thread,
+- provider-side thread metadata,
+- native tool state where available,
+- continuity for provider-specific behavior.
+
+It also forces every switch to depend on full summarization quality. Full summaries are useful fallback artifacts, but they should not be the default when a previous provider thread can be safely resumed.
+
+## Why Not Resume Without Summary?
+
+Because the app thread moved on while the provider was inactive. The resumed provider would not know what another provider did. That creates wrong answers, stale plans, and unsafe file assumptions.
+
+Returning to a provider requires a handoff summary unless no runs happened since that provider last participated.
+
+## Provider Thread Coverage
+
+Provider threads have native coverage and handoff coverage.
+
+```ts
+type ProviderThreadCoverage = {
+  providerThreadId: ProviderThreadId;
+  nativeRunOrdinals: number[];
+  handoffIds: ContextHandoffId[];
+};
+```
+
+For the example above:
+
+```text
+C1 native runs: 1,2,3,4,5,9
+C1 handoffs: H2 covering 6-8
+
+L1 native runs: 6,7,8
+L1 handoffs: H1 covering 1-5
+```
+
+The app thread remains the source of truth for full history.
+
+## Handoff Artifact
+
+A handoff is explicit graph data. In the broader model, `ContextTransfer` records source, target, relationship type, and resolution status. `ContextHandoff` is the materialized portable context artifact used when the transfer cannot be satisfied by native provider continuity.
+
+```ts
+type ContextHandoff = {
+  id: ContextHandoffId;
+  transferId: ContextTransferId;
+  threadId: ThreadId;
+  targetRunId: RunId;
+  fromProviderThreadIds: ProviderThreadId[];
+  toProviderThreadId: ProviderThreadId;
+  coveredRunOrdinals: { from: number; to: number };
+  strategy:
+    | "delta_since_target_last_seen"
+    | "full_thread_summary"
+    | "checkpoint_summary"
+    | "manual_context";
+  summaryText: string;
+  status: "pending" | "ready" | "failed" | "superseded";
+  createdByProvider: ProviderKind | null;
+  createdAt: string;
+  updatedAt: string;
+};
+```
+
+The handoff should be linked to the run that consumes it. If the same summary is regenerated, the old handoff is superseded rather than mutated invisibly.
+
+## Switch Flow
+
+```text
+start run with target provider P
+  -> find current app thread history
+  -> find best ProviderThread for P
+  -> decide handoff strategy
+  -> generate ContextHandoff if needed
+  -> ensure ProviderSession for P
+  -> ensure/resume/create target ProviderThread
+  -> send provider turn with handoff context + user message
+```
+
+The user message remains the actual run input. The handoff context is a separate preamble/system/developer/synthetic-user context depending on provider capability.
+
+## Strategy Selection
+
+### Session cleanup
+
+Closing a provider session waits up to 30 seconds for cleanup. A timeout returns an error, records the session as `error`, and leaves cleanup running. It does not confirm that the old process has stopped.
+
+While cleanup is pending, the session manager rejects reuse of the releasing session ID, creation of sessions for its recorded app threads, and new attachments of those threads to another session. A thread already attached to a different live session can keep reusing that session. Repeated close or detach requests wait for the original cleanup. Successful cleanup removes this block; failed cleanup keeps it until the environment restarts. Other threads can still open sessions.
+
+This applies when a session is released. Detaching a thread from a shared session does not necessarily release that session, so this is not a complete shared-process account-switching protocol.
+
+### Handoff selection
+
+Recommended strategy order:
+
+1. No handoff: target provider thread already has current app run coverage.
+2. Delta handoff into existing provider thread: target provider thread can resume and only missed a run range.
+3. Full thread handoff into existing provider thread: target provider can resume, but delta chain is too complex.
+4. Full thread handoff into new provider thread: target provider resume failed, settings are incompatible, or old context is stale.
+5. Unsupported: provider cannot accept handoff context and no safe reconstruction path exists.
+
+## Staleness Policy
+
+The app should be able to decide that returning to an old provider thread is no longer appropriate.
+
+Possible staleness signals:
+
+- too many off-provider runs since last use,
+- too many chained handoffs,
+- target provider model/runtime mode changed incompatibly,
+- provider thread resume failed,
+- prior provider thread was rolled back or forked in a conflicting way,
+- user selected "clean context",
+- handoff summary would exceed provider context policy.
+
+When stale, create a new provider thread with `full_thread_summary`.
+
+## Summarization Source
+
+Summaries can be generated by:
+
+- the provider being left,
+- the provider being entered,
+- a configured summarization provider,
+- a local deterministic summarizer for structured artifacts.
+
+The summary generator is not necessarily the target provider. The handoff records `createdByProvider` so quality and provenance can be inspected later.
+
+## What The Summary Should Contain
+
+The summary should be app-thread canonical, not provider transcript-only.
+
+Include:
+
+- user goals and constraints,
+- decisions made,
+- files changed,
+- commands/tests run,
+- plans/todo state,
+- unresolved approvals/questions,
+- current checkpoint/diff summary,
+- known failures,
+- relevant subagent results.
+
+Do not include:
+
+- irrelevant provider protocol noise,
+- hidden chain-of-thought,
+- stale tool output that is superseded by later runs,
+- large diffs when a file summary is enough.
+
+## Checkpoint Interaction
+
+Provider switching does not change checkpoint ownership. Checkpoints still attach to app runs.
+
+However, handoff generation should reference the latest checkpoint and diff summary so the next provider has a correct workspace-state picture.
+
+```text
+run N completed
+  -> checkpoint N captured
+switch provider for run N+1
+  -> handoff includes summary through checkpoint N
+```
+
+## Rollback Interaction
+
+Rollback invalidates handoffs that cover rolled-back runs.
+
+```text
+rollback to run 5
+  -> runs 6+ marked rolled_back
+  -> handoffs covering 6+ marked superseded
+  -> provider threads whose native/handoff coverage includes 6+ marked divergent or rolled back by capability
+```
+
+If the active provider supports provider rollback, call it. Otherwise, create a new provider thread from the retained app-thread summary when work resumes.
+
+## Forking Interaction
+
+Forking from a mixed-provider app thread should record app-thread lineage and a source point without requiring provider selection at fork time. Provider context is resolved lazily when the first run starts on the fork.
+
+Examples:
+
+- Fork from run 5 on Codex, first fork run uses Codex: prefer Codex native fork if the source refs are strong.
+- Fork from run 5 on Codex, first fork run uses Claude: build portable context lazily at first dispatch.
+- Fork from app checkpoint with no provider-native thread: create target provider thread with checkpoint/full-thread context.
+- Fork from subagent provider thread: use the subagent's provider thread directly if stable, otherwise fall back to portable context.
+
+## Data Model Changes
+
+Provider switching requires:
+
+- `Run.provider`
+- `Run.providerThreadId`
+- `Run.contextHandoffId`
+- `ContextTransfer`
+- `ProviderThread.firstRunOrdinal`
+- `ProviderThread.lastRunOrdinal`
+- `ProviderThread.handoffIds`
+- `ContextHandoff`
+- provider capabilities for handoff support
+
+The app does not need separate conversation threads for provider switches. It needs multiple provider threads attached to the same app thread.

+# Testing Strategy
+
+V2 should be validated with a small number of high-value integration tests rather than a large suite of unit tests that mock away the behavior being tested.
+
+The goal is not "no test doubles ever." The goal is that test doubles exist only at true process, network, clock, id, and filesystem boundaries. Core orchestration behavior must run for real.
+
+## Testing Principle
+
+The default V2 test shape is:
+
+```text
+command dispatch
+  -> real Orchestrator
+  -> real ProviderAdapter
+  -> replayed ProviderRuntime transport
+  -> real adapter normalizer
+  -> real V2 event store/sink using production persistence semantics
+  -> real V2 projection/projector
+  -> real Checkpoint policy
+  -> assertions
+```
+
+The replay framework replaces the external provider process or network stream. It does not replace the adapter, normalizer, command/event infrastructure, projection reducers/projectors, checkpoint policy, or business logic.
+
+Raw provider frames in replay transcripts are realistic transport evidence. In production, equivalent raw frames are diagnostic log data with bounded retention. Integration tests should still use real normalized orchestration persistence/projections so replay input exercises the same adapter and orchestration paths as live provider output.
+
+## Allowed Test Substitutes
+
+Allowed substitutes:
+
+- provider runtime transport, backed by deterministic replay transcripts.
+- Effect runtime time, controlled in tests with `TestClock` from `effect/testing`.
+- Effect `Random`, provided with a deterministic test implementation for stable UUIDs/numbers.
+- temporary filesystem/worktree.
+- temporary database or in-memory database with the same repository interfaces.
+- fake process supervisor only when it is testing process failure behavior directly.
+
+Not allowed in integration tests:
+
+- mocked orchestrator.
+- mocked provider adapter.
+- mocked provider event normalizer.
+- mocked command/event infrastructure or V2 event sink.
+- mocked projection reducer.
+- mocked checkpoint service behavior.
+- mocked provider capability policy.
+- pre-normalized domain events used as the input for adapter tests.
+- custom clock/id services that duplicate Effect's `Clock`, `DateTime`, or `Random` services.
+
+Pure reducer tests are still valid, but they should be few and targeted. They should test projection invariants directly, not replace integration coverage.
+
+Production code should read time through Effect runtime APIs, such as `DateTime.now` and `Clock.currentTimeMillis`, not through `Date.now` or ad hoc wrappers. Production code should allocate random values through `effect/Random`, not through direct `crypto.randomUUID`, `Math.random`, or a custom global id generator.
+
+Tests should provide Effect test services:
+
+```ts
+import { TestClock } from "effect/testing";
+```
+
+The id allocator can still expose domain-specific helpers such as `newRunId` or `newNodeId`, but those helpers should be implemented on top of `Random` so test layers can produce deterministic values without mocking orchestration logic.
+
+## Generic Replay Runtime
+
+Replay must be provider-neutral. Codex NDJSON fixtures are one provider's transcript format, not the framework itself.
+
+```ts
+type ProviderReplayTranscript = {
+  provider: ProviderKind;
+  protocol: string;
+  version: string;
+  scenario: string;
+  entries: ProviderReplayEntry[];
+};
+
+type ProviderReplayEntry =
+  | {
+      type: "expect_outbound";
+      label?: string;
+      frame: unknown;
+    }
+  | {
+      type: "emit_inbound";
+      label?: string;
+      frame: unknown;
+      afterMs?: number;
+    }
+  | {
+      type: "runtime_exit";
+      status: "success" | "error" | "cancelled";
+      error?: unknown;
+    };
+```
+
+The replay runtime owns deterministic transport semantics:
+
+- ordered inbound event emission.
+- outbound command assertion.
+- pause/resume and timing control.
+- runtime exit/error simulation.
+- resume cursor/session restoration.
+- transcript metadata validation.
+
+The replay runtime must not know what a turn, plan, approval, subagent, or checkpoint means. Provider adapters interpret provider-specific frames.
+
+Recovery tests use replay only at the provider transport boundary. App restart is tested by tearing down and recreating the outermost orchestrator/server layer against durable persistence. Idle cleanup and crash recovery are tested through production lifecycle services such as the session reaper or runtime recovery policy. Tests must not add adapter or orchestrator methods whose only purpose is to restart sessions for assertions.
+
+## Provider Transcript Formats

+Each provider can have its own raw frame format inside the generic replay envelope.
+
+Examples:
+
+```text
+Codex replay transcript
+  -> JSON-RPC app-server requests/responses/notifications
+  -> consumed by CodexAdapter
+
+Claude replay transcript
+  -> Claude Agent SDK query() outbound options and yielded SDKMessage chunks
+  -> consumed by ClaudeAdapter
+
+Cursor replay transcript
+  -> Cursor Agent SDK open/send calls and ordered onDelta/run results
+  -> consumed by CursorAdapter
+
+OpenCode replay transcript
+  -> OpenCode SDK requests/responses plus ordered SSE events
+  -> consumed by OpenCodeAdapter
+
+ACP replay transcript
+  -> logical JSON-RPC requests/responses/notifications over a strict NDJSON peer
+  -> consumed by AcpAdapter and a provider flavor (Grok or ACP Registry)
+```
+
+Fixtures should preserve raw provider evidence as closely as possible. Expected V2 events or projections are assertions, not fixture input.
+
+For Claude, the initial replay boundary is the async iterable returned by the Agent SDK `query()`
+call. A transcript should include the `query` prompt/options we sent and then replay the raw
+`SDKMessage` chunks in provider order. This intentionally tests the V2 adapter against real Claude
+SDK output; it does not test the SDK's own subprocess or transport parser.
+
+ACP fixtures run against a child-process replay peer that validates every outbound frame and
+serves recorded inbound frames. This replaces only the external ACP driver transport; the shared
+runtime, adapter normalization, orchestration, persistence, and projections remain production code.
+The generic ACP Registry harness retargets protocol-standard ACP transcripts;
+provider-extension transcripts remain scoped to the flavor that owns the extension.
+
+OpenCode fixtures replace the SDK client at its HTTP/SSE boundary. They must preserve races between
+request responses and SSE events, because user messages and terminal `session.status` events can
+arrive before the corresponding `promptAsync` or `abort` response. Subagent fixtures must retain
+both parent and child session ids so root-only terminal behavior remains testable.
+
+Provider transcript recorders live with the server orchestration testkit, not with provider client
+packages. Use `bun run record:codex-replay -- --scenario <name>` for Codex app-server transcripts
+and `bun run record:claude-replay -- --scenario <name>` for Claude Agent SDK transcripts. Use
+`pnpm --filter t3 record:cursor-replay -- --scenario <name>` for Cursor Agent SDK transcripts.
+
+## Contract Test Levels
+
+Recommended levels:
+
+1. Schema tests for V2 contracts.
+2. Pure projection tests for hard invariants.
+3. Provider adapter replay tests from raw transcript to V2 domain events.
+4. Full orchestration integration tests from commands through replay runtime to final projection.
+
+The fourth level is the most important one. It is the test that catches lifecycle mismatches such as child turns closing parent runs or checkpoints being captured too early.
+
+## First Ten Integration Tests
+
+V2 should start with roughly ten strong tests:
+
+1. `simple`: sending one message creates one run, one root node, one provider turn, one assistant response, and one root checkpoint.
+2. `multi_turn`: follow-up messages create monotonically ordered app runs on the same app thread.
+3. `message_steering`: steering attaches to the active run intent instead of becoming an unrelated run.
+4. `turn_interrupt`: interrupt acknowledgement does not complete the run until the provider terminal event arrives.
+5. `steering_restart_fallback`: a provider without native steering interrupts the active attempt and creates a replacement attempt under the same run.
+6. `subagent`: child provider turns create nested execution nodes and never complete the parent run.
+7. `subagent_checkpoint`: child/subagent nodes create nested checkpoint scopes without advancing the app run count.
+8. `thread_rollback`: rollback targets checkpoint scopes and reconciles provider rollback snapshots.
+9. `approval_request`: provider approval callbacks become durable runtime requests and are resolved through the real adapter path.
+10. `provider_switch_return`: switching away from a provider creates a context handoff, and switching back resumes the prior provider thread with a delta handoff.
+
+Additional tests should be added only when they protect a new invariant or reproduce a real failure mode.
+
+## Fixture Rules
+
+- Fixtures are raw provider transcripts, not mocked domain events.
+- Fixtures should include enough outbound expectations to prove the app sent the correct provider commands.
+- Fixtures should include protocol metadata, provider version, model, cwd policy, and capture timestamp.
+- Fixture playback must be deterministic under Effect `TestClock` and deterministic `Random` layers.
+- When a provider transcript is generated from a real run, keep the original provider frame ordering.
+- Redaction should preserve ids, method names, lifecycle ordering, and correlation structure.
+- Fixture transcripts are test input and diagnostic evidence. They do not imply production stores all raw provider frames in SQLite.
+
+## Assertions
+
+Assertions should prefer final projections and durable normalized orchestration events over incidental implementation calls.
+
+Good assertions:
+
+- duplicate command dispatch returns the original receipt sequence without replaying provider transport.
+- stored-event sequence monotonicity.
+- snapshot sequence plus stream-after-sequence behavior.
+- run status and ordinal.
+- active/final run attempt.
+- execution node parent/child structure.
+- provider thread and provider turn correlation.
+- checkpoint scope hierarchy.
+- pending/resolved runtime requests.
+- handoff coverage and strategy.
+- replay transcript frame count and normalized event count when relevant.
+
+Weak assertions:
+
+- exact internal function call counts.
+- private helper invocation order.
+- mocked callback arguments below the adapter/runtime boundary.
+
+## Implementation Order
+
+Testing infrastructure should be built before production rewrites:
+
+1. V2 contract schemas.
+2. Effect service definitions.
+3. provider runtime transport abstraction.
+4. generic replay runtime.
+5. Codex, Claude, Cursor, OpenCode, and ACP transcript loaders for app-owned provider replay fixtures.
+6. projection reducer tests for core invariants.
+7. full command-to-projection integration tests.
+8. production layers.
+
+This keeps the architecture executable while it is being built and prevents tests from validating only simplified mocks.

+# Thread Lineage And Context Transfer
+
+Forking, provider handoff, merge-back, and subagents are separate product features, but they should share one orchestration model. The common primitive is not "fork" and not "summary". It is:
+
+```text
+thread relationship
+  + source point
+  + optional context transfer resolution
+```
+
+The app should preserve lineage cheaply and resolve expensive provider/context work lazily when a run actually needs it.
+
+## Product Use Cases
+
+### Fork To Explore
+
+A user forks an existing app thread to explore a tangent without polluting the source thread's context.
+
+```text
+source AppThread
+  -> user forks from stable source point
+  -> new idle AppThread
+  -> no provider chosen yet
+  -> first message chooses provider/model
+```
+
+If the first run on the fork uses the same provider as the source and the provider supports native fork, use the provider-native fork path. If it uses a different provider, materialize portable context at first dispatch.
+
+### Continue Same Thread With A Different Agent
+
+A user continues the same app thread with another provider. This is not a new app thread, but it is still a context transfer.
+
+```text
+AppThread runs 1-5 with Codex
+user sends run 6 with Claude
+  -> resolve context transfer from Codex-backed source state to Claude
+  -> start Claude provider thread with handoff context + user message
+```
+
+The app thread remains the canonical conversation. Provider-native threads are backing handles with explicit coverage.
+
+### Merge A Fork Back Into Its Source
+
+A user explores deeply in a fork, then brings the result back to the source thread.
+
+```text
+source thread at source point S
+fork explores runs F1-Fn
+user sends next message in source thread with "bring this back"
+  -> build delta from S to fork latest stable point
+  -> inject delta context with the source-thread user message
+```
+
+This is not a full source-thread provider switch. It is a targeted context transfer from the fork back to the original thread.
+
+### Subagents
+
+Subagents are the same family of operation with a different creator and lifecycle contract.
+
+Native subagents:
+
+- the provider spawns the child through its native capability;
+- the app observes native child refs/events;
+- the child is modeled as a child execution node and, when useful, as a related app subthread.
+
+Cross-provider T3 subagents:
+
+- the parent agent calls an app-owned tool;
+- the app creates a child app thread/run with a relationship to the parent;
+- the child result is transferred back to the parent as a subagent result context transfer.
+
+The shared model should make user forks and agent-created subthreads feel like the same graph shape with different `createdBy` and lifecycle policy.
+
+## Core Concepts
+
+### Thread Relationship
+
+Thread relationship describes why a target thread or run exists relative to another thread.
+
+```ts
+type ThreadRelationshipKind =
+  "fork" | "provider_handoff" | "merge_back" | "subagent_spawn" | "subagent_result";
+```
+
+Relationships are product-level and provider-neutral. A fork is not the same thing as a provider-native fork. A provider-native fork is one possible resolution strategy for a fork relationship.
+
+### Source Point
+
+Source point describes the exact state being transferred.
+
+```ts
+type ContextSourcePoint = {
+  threadId: ThreadId;
+  runId?: RunId;
+  checkpointId?: CheckpointId;
+  turnItemId?: TurnItemId;
+  providerThreadRef?: NativeThreadRef;
+  providerTurnRef?: NativeTurnRef;
+};
+```
+
+Stable source points should prefer completed runs/checkpoints. Active runs are harder because provider chunks may still arrive and checkpoints may not be final.
+
+### Context Transfer
+
+Context transfer is the durable operational record that connects source and target. It is cheap to create and may stay unresolved until first use.
+
+```ts
+type ContextTransfer = {
+  id: ContextTransferId;
+  type: ThreadRelationshipKind;
+  sourceThreadId: ThreadId;
+  targetThreadId: ThreadId;
+  sourcePoint: ContextSourcePoint;
+  basePoint?: ContextSourcePoint;
+  sourceProvider?: ProviderKind;
+  targetProvider?: ProviderKind;
+  status:
+    "pending" | "resolved_native" | "resolved_portable" | "failed" | "consumed" | "superseded";
+  resolution?: ContextTransferResolution;
+  createdBy: "user" | "agent" | "system";
+  createdAt: string;
+  consumedAt?: string;
+};
+```
+
+`basePoint` is used for delta transfers, especially merge-back. For a fork merge-back, `basePoint` is the original fork source point and `sourcePoint` is the fork's latest stable point.
+
+### Context Handoff
+
+Context handoff is the expensive materialized context artifact. It is created lazily only when native transfer is unavailable or insufficient.
+
+```ts
+type ContextHandoff = {
+  id: ContextHandoffId;
+  transferId: ContextTransferId;
+  kind: "portable_context" | "delta_context" | "checkpoint_context";
+  payload: PortableContextPayload;
+  createdAt: string;
+};
+```
+
+Context handoffs should be auditable app artifacts, not hidden prompt concatenation.
+
+### Resolution Strategy
+
+Resolution decides how the target provider/thread receives the source context.
+
+```ts
+type ContextTransferResolution =
+  | {
+      strategy: "native_fork";
+      providerThreadRef: NativeThreadRef;
+    }
+  | {
+      strategy: "portable_context";
+      contextHandoffId: ContextHandoffId;
+    }
+  | {
+      strategy: "delta_context";
+      contextHandoffId: ContextHandoffId;
+    }
+  | {
+      strategy: "checkpoint_context";
+      contextHandoffId: ContextHandoffId;
+    };
+```
+
+Same-provider forks should prefer `native_fork` when the source native refs are strong and the adapter supports it. Cross-provider handoff and merge-back usually require a context handoff.
+
+## Lazy Resolution
+
+Fork creation should be cheap:
+
+```text
+thread.fork
+  -> create target AppThread
+  -> record thread relationship / ContextTransfer(status=pending)
+  -> do not create provider session
+  -> do not create provider thread
+  -> do not build portable context
+```
+
+First dispatch on a pending fork resolves the transfer:
+
+```text
+first run on fork chooses provider P
+  -> find pending fork ContextTransfer
+  -> if source provider == P and native fork is supported:
+       resolve native fork
+     else:
+       materialize portable context
+  -> create/resume provider thread
+  -> send handoff/native context + user message
+```
+
+This avoids forcing users to choose an agent at fork time and avoids generating summaries that may never be used.
+
+## Runtime Entry Point
+
+Run startup should have one provider-neutral hook:
+
+```ts
+resolveStartContext({
+  threadId,
+  provider,
+  message,
+}): StartContextResolution
+```
+
+This hook checks pending context transfers targeting the thread/run and chooses a strategy:
+
+1. No transfer needed: target provider already has current coverage.
+2. Native transfer: same provider and adapter supports native fork/resume.
+3. Portable transfer: build a context handoff and inject it into the run.
+4. Delta transfer: build the changes between `basePoint` and `sourcePoint`.
+5. Unsupported: fail explicitly before provider work starts.
+
+Provider adapters own native details. The orchestrator owns the relationship, source point, durable transfer record, and command receipts.
+
+For Codex, native `thread/fork` forks the latest native thread state. When the app source point is an earlier completed provider turn, the Codex adapter resolves that provider-specific detail by forking first, then rolling back the forked native thread by the number of later terminal provider turns. The orchestrator still passes a provider-neutral source point and source provider-turn history; it does not encode Codex rollback policy.
+
+## Data Ownership
+
+`AppThread` should store lightweight browsing lineage:
+
+```ts
+type AppThreadLineage = {
+  parentThreadId: ThreadId | null;
+  relationshipToParent: "fork" | "subagent" | null;
+  rootThreadId: ThreadId;
+};
+```
+
+Operational transfer details should live in `ContextTransfer`, not directly on `AppThread`, because a thread can participate in many transfers:
+
+- created by fork;
+- later switched to another provider;
+- later merged back to its source;
+- later spawned subagents.
+
+## Checkpoint And Active-Run Policy
+
+The first implementation should prefer stable source points:
+
+- completed run checkpoint;
+- explicit checkpoint;
+- idle provider thread with known coverage.
+
+Forking or handoff from an active run should either:
+
+- use the latest completed checkpoint, or
+- be rejected until active-run semantics are designed.
+
+Do not silently fork from partially streamed provider state. That weakens correlation and makes replay/recovery difficult.
+
+## Current Implementation Boundary
+
+The first backend slice implements lazy same-provider fork resolution:
+
+- `thread.fork` creates a target app thread with fork lineage and a pending `ContextTransfer`.
+- `thread.fork` does not create a provider session, provider thread, provider turn, or portable context artifact.
+- The first dispatch on the fork resolves the pending transfer. For Codex-to-Codex forks with strong native refs and `thread/fork` support, the orchestrator uses the provider-native fork path and records `resolved_native` then `consumed`.
+- Cross-provider or otherwise non-native fork transfers materialize a portable `ContextHandoff`
+  lazily on the target thread's first dispatch.
+- Active source runs are rejected for explicit run/checkpoint forks; `latest_stable` resolves to the latest completed checkpointed run.
+
+This keeps the runtime aligned with the architecture while making portable context explicit and
+auditable through `ContextTransfer` and `ContextHandoff` records.
+
+## Relationship To Provider Switching
+
+Provider switching is a context transfer where `sourceThreadId === targetThreadId` and the target provider differs from the current active provider.
+
+Returning to a prior provider is also a context transfer, usually a delta from the provider's last covered run range to the current app-thread point.
+
+The [Provider Switching And Context Handoff](./provider-switching-and-context.md) document describes strategy selection for that specific feature. This document defines the broader model shared by provider switching, forks, merge-back, and subagents.

+# Cursor
+
+Cursor V2 runs through the official [`@cursor/sdk`](https://cursor.com/docs/api/sdk/typescript)
+TypeScript package. It does not use Cursor's ACP transport for V2 execution.
+
+## Prerequisites
+
+- Node.js 22.13 or newer. The repository's supported Node version satisfies this requirement.
+- A Cursor API key in `CURSOR_API_KEY`. Provider-instance environment variables override the host
+  environment in the same way as the other providers.
+- A model accepted by the Cursor SDK. `auto` is sent to the SDK as its `default` model selection.
+
+The adapter currently uses the SDK's local-agent runtime so runs operate in the selected T3 Code
+workspace. Cursor cloud agents need repository and cloud-environment configuration that T3 Code does
+not expose yet.
+
+## V2 Capability Mapping
+
+The adapter supports:
+
+- creating and resuming local Cursor agent threads;
+- changing the model and model parameters between turns;
+- assistant text, reasoning, tool output, plans, and todo streaming;
+- thread-scoped T3 Code MCP tools;
+- image attachments;
+- interruption, queued app messages, and orchestrator-owned interrupt/restart steering;
+- provider conversation snapshots through `Agent.messages.list()`;
+- Cursor `task` subagents, projected as read-only child app threads with their tool activity and
+  final result.
+
+The public SDK does not currently expose native agent fork, conversation rollback, active steering,
+or interactive approval callbacks. Direct active steering is advertised as unsupported, while V2
+steering uses the orchestrator's interrupt-and-restart path and preserves the app run identity across
+provider turns. Same-provider Cursor forks use the orchestrator's portable full-thread context
+handoff into a fresh Cursor agent. The SDK has in-process custom callback tools, but the V2 adapter
+intentionally uses the authenticated, thread-scoped MCP server instead.
+
+Portable handoffs summarize eligible timeline items and can omit the end of long messages. Read
+[Context in portable handoffs](./portable-handoffs.md) before using a fork for work whose exact
+instructions must carry forward.
+
+Cursor task events include an `agentId`, but the local SDK does not register that identifier as a
+resumable agent: `Agent.resume()` returns `AgentNotFoundError`. The adapter therefore does not attach
+a provider thread to native task projections or advertise subagent thread IDs. Sending a new message
+from a projected child starts a new Cursor agent rather than pretending to resume the task runtime.
+
+Runtime modes map to the controls the local SDK exposes: full access disables its sandbox, while
+restricted modes and explicit non-full-access sandbox policies enable it. Explicit approval policy
+overrides also control Cursor Auto-review. Auto-review is not represented as an interactive T3 Code
+approval flow.
+
+The existing Cursor binary path and API endpoint settings belong to the CLI/ACP integration. Cursor
+V2 execution does not launch that binary, and the SDK does not expose an API endpoint override.
+
+## Replay And Live Testing
+
+Cursor replay fixtures preserve the SDK boundary: agent open/resume, sends, ordered `onDelta`
+updates, terminal results, cancellation, message snapshots, and close. The real V2 adapter,
+orchestrator, event store, projections, and checkpoint logic still run in tests.
+
+Record a fixture against the real SDK with:
+
+```bash
+pnpm --filter t3 record:cursor-replay -- --scenario simple
+```
+
+Use `--out <path>` to record a temporary probe without replacing a checked-in fixture. Supported
+scenarios are listed by the recorder when an invalid scenario is supplied.

+# Context in portable handoffs
+
+T3 Code sometimes starts a fresh provider session instead of resuming a provider's native session.
+This happens when you switch providers, continue through portable restart steering, or use a fork
+that the provider cannot resume itself.
+
+The new provider receives a text handoff. This handoff is useful context, but it is not a copy of
+the original provider session. For each included user message, assistant message, command, or prior
+handoff, T3 Code collapses whitespace and keeps up to 240 characters from the beginning. File
+changes appear by filename, and checkpoints appear with a file count. Other timeline items may not
+appear in the handoff.
+
+Text near the end of a long message can be omitted. Before switching providers or continuing a
+portable fork, put the current goal, hard constraints, and any unresolved failure in a short message.
+You can also paste the exact detail again after the new provider starts.
+
+This 240-character rule is different from migration of older threads. A migrated thread gives its
+first fresh provider session the newest transcript suffix within a separate 32,000-character budget.
+See [Threads from older T3 Code versions](./thread-migration.md) for that migration path.

+# Threads from older T3 Code versions
+
+When a server first starts with the current orchestration system, it brings its existing threads
+forward automatically. You do not need to run an import command.
+
+The migrated thread keeps its title, project, provider and model selection, permission and
+interaction modes, branch or worktree, archive state, settlement state, snooze and pin state, and
+linked pull request. T3 Code also brings over user and assistant messages, their timestamps, and
+supported attachments. Large histories may appear in stages while the server imports transcripts.
+
+The migration does not recreate the old provider's live session. It also does not convert old run
+records, checkpoints and diffs, tool activity, approval history, or proposed plan history into the
+new format. These items may be absent from a migrated timeline even though the conversation text is
+present.
+
+## Continuing a migrated thread
+
+The first new message starts a fresh provider session. T3 Code gives that session the newest part of
+the old user and assistant transcript, up to 32,000 characters. Earlier text remains visible in the
+thread, but the provider does not receive it automatically.
+
+Before continuing a long or important thread, read the recent transcript and include any older
+requirements the agent still needs in your next message. Starting a new thread and pasting a short
+handoff is also a good choice when the old conversation contains conflicting instructions.
+
+## Keeping a recovery copy
+
+T3 Code does not currently have a whole-thread export command. Before a major server update, stop
+the server and copy its `userdata` directory to a safe location. The default is
+`~/.t3/userdata`; a server started with `--home-dir <path>` uses `<path>/userdata`.
+
+If a migrated transcript is missing from the app, keep that copy unchanged. You can inspect the
+old transcript without starting a server against it:
+
+```sh
+sqlite3 -readonly /path/to/recovery-copy/state.sqlite
+```
+
+At the SQLite prompt, list recent legacy threads:
+
+```sql
+.headers on
+.mode tabs
+SELECT thread_id, title, updated_at
+FROM projection_threads
+ORDER BY updated_at DESC;
+```
+
+Then print one transcript, replacing `<thread-id>` with the value from the first query:
+
+```sql
+SELECT role, text, created_at
+FROM projection_thread_messages
+WHERE thread_id = '<thread-id>'
+  AND role IN ('user', 'assistant')
+ORDER BY created_at, message_id;
+```
+
+Open only the copied database. Do not edit it or point a newer or older server at your recovery
+copy. If the affected environment is remote, make and inspect the copy on the machine that runs
+that environment.
