+"""Shared saved-memory context, independent of the chat route graph.
+
+Normal chat retains its existing embedding-backfill behavior. Planning callers
+must pass ``read_only=True`` and ``authorized_user_id`` from the authenticated
+server context, never from request JSON. Personal scope must equal that user;
+group scope is revalidated through ``assert_group_role`` before any memory read.
+Only user/group scopes are supported by the existing memory store. Conversation
+and agent IDs are provenance, not authorization, and must already be authorized
+by the caller. The store intentionally recalls across conversations in a scope.
+
+Read-only context performs no autosave or embedding backfill. Facts without a
+stored embedding are omitted; query embedding generation itself does not write
+memory. Returned context, thoughts and citations have bounded values and counts.

+# Capability-aware orchestration planning
+
+**Version: 0.261.104**
+
+**Fixed in version: 0.261.104**, tracked by `VERSION` in
+`application/single_app/config.py`.
+
+## Issue and root cause
+
+Orchestration could describe live retrieval as unauthorized even when the user
+expected the deployment's research capabilities to be available. Planner context
+combined the real server-resolved capability list with
+`user_selected.web_search: false`, conflating an unchecked default with a denial.
+Short requests could also bypass the planner entirely.
+
+Agent discovery had a separate shape mismatch: group-ID strings reached catalog
+code expecting group records. Its broad fallback then looked like a successfully
+resolved empty catalog. Initial model failures likewise looked like successful
+answer-only plans.
+
+The existing balanced research-depth guidance had not been removed. These fixes
+correct the surrounding context and failure contracts rather than introducing
+topic-specific routing.
+
+## Requirements versus availability
+
+The initial planner receives separate, authoritative information:
+
+| Context | Contract |
+| --- | --- |
+| Available capabilities | Server feature gates, orchestration allowlist, current caller access, and resource prerequisites. Descriptors include arguments, outputs, costs, and per-plan limits. |
+| Positive requirements | Selected supported controls, documents, and agents. Initial validation rejects silently dropped selections. |
+| Neutral controls | An unchecked control, including legacy false Web values, is not a veto. |
+| Authorized resources | Relevant documents, governed actions, current agent records, bounded conversation context, and enabled read-only saved memory. |
+| Time and prior activity | Current UTC time and bounded earlier-run summaries; neither grants permissions nor proves evidence was retrieved. |
+
+The planner can use another available capability without a manual opt-in. An
+explicit instruction such as "do not browse" remains an instruction. Selected
+workspace and document filters continue to bound retrieval; the fix does not
+widen authorization.
+
+Selected Deep Research no longer requires selecting Web first. Automatic web
+discovery still depends on the server's Web Search setting. Unsupported Image
+generation and ineligible URL controls are not silently converted into
+orchestration requirements.
+
+An existing Image selection blocks submission until the user chooses regular
+Chat with Image or explicitly excludes Image for this orchestration message.
+That exclusion does not erase the ordinary-chat Image preference. URL
+eligibility uses the resolved message, including attached prompts, rather than
+only the draft editor text.
+
+## Planning, editing, and execution
+
+Every Orchestrate request invokes the planner, including short questions.
+The model can choose a direct answer when context is sufficient. There is no
+keyword router, fixed research quota, compulsory Web step, or mandatory Deep
+Research step.
+
+Discovery and provider failures are explicit errors, not empty catalogs or
+successful answer-only plans. Missing, empty, or non-list model-authored steps
+are rejected before normalization; a missing final answering step is repaired
+only when real planned work remains. A failed edit preserves the prior plan. Later
+manual/editor narrowing remains possible and reports when original selected
+work is removed.
+
+The agent and action catalogs share fresh membership resolution. Client group
+IDs or records narrow current, role-checked group records; supplied names and
+roles are not trusted. Selected agents are resolved from the authorized catalog.
+
+Before execution, current feature and resource gates are rechecked. Stored plan
+usage and positive composer requirements are separate: restoring a model-chosen
+Web step does not turn the Web button into an original user selection. Completed
+usage reports come from actual executed capabilities, not merely proposed steps.
+
+## Read-only saved memory
+
+With **Fact Memory** enabled (`enable_fact_memory_plugin`), initial planning,
+planner edits, and final answers reuse the existing instruction/fact reader.
+Recall is limited to eight instructions and four relevant embedded facts, with
+each value bounded to 2,000 characters. Saved instructions are preferences
+subordinate to the current request; facts are background context, not permissions
+or proof of current external conditions.
+
+In a private conversation, personal/public source modes use the caller's memory.
+Group/all source modes with a selected group use the first active group's memory,
+after fresh membership authorization. Selecting an ID never grants access, and a
+denied group does not fall back to personal memory. Public document access does
+not create a public-memory scope.
+
+Shared conversations and their hidden source records receive no saved memory.
+Owning a source record does not establish a private audience; the owner-only
+orchestration API does not establish shared-memory authorization. This limitation
+is reported in planner context rather than treating personal memories as shared.
+
+Only audience and scope markers, not recalled prompt text, are saved with a plan
+or cached clarification outcome. These markers identify what was used; they do
+not grant access. Audience and current membership are checked before publishing
+plans, questions, and their replays. Each cached outcome keeps its own scope
+even if a later continuation changes sources.
+
+Recall and authorization are repeated before final synthesis so changed
+membership or disabled memory cannot reuse a stale payload. The actual recalled
+scope is checked again after the model call, before an answer or its memory
+citations can be published. Final answers retain the existing `fact_memory`
+citation format and provenance.
+
+Planning and orchestration recall do not autosave facts or backfill embeddings.
+Missing embeddings are reported as unavailable, while usable instruction
+memories can remain. Query embeddings may still require a model request.
+Disabled memory performs no memory-store or embedding access. Ordinary chat
+keeps its existing backfill behavior.
+
+## Files and regression coverage
+
+The contract is implemented in `functions_orchestration_context.py`,
+`functions_orchestration_registry.py`, `functions_orchestration_planner.py`,
+`functions_orchestration_schema.py`, the editing/revision modules, and
+`route_backend_orchestration.py`. Agent discovery uses
+`functions_action_catalog.py` and `functions_agent_catalog.py`. The V2 composer,
+request builder, plan normalization, and stores preserve positive selections.
+
+`functional_tests/test_orchestration_capability_context.py` exercises real group
+record resolution, authorization narrowing, requirements, and notice projection.
+Research-selection, conversation, clarification, revision, and hydration suites
+cover their related contracts. Browser tests cover the real composer and the
+combined editor/Flask workflow.
+
+`functional_tests/test_orchestration_memory_context.py` exercises the real reader
+through planning, editing, and final synthesis, including citations, scope
+revocation, audience changes during planning and synthesis, clarification replay,
+disabled memory, missing embeddings, and no writes.
+`functional_tests/test_fact_memory_read_only_context.py` covers the bounded
+reader and unchanged ordinary-chat backfill. Integration lives in
+`functions_orchestration_memory.py`, the executor/respond adapter, and the
+existing planning/revision routes.
+
+## Evaluation boundaries
+
+The research-planning evaluator captures actual serialized synthetic contexts,
+capability projections, guidance, and source fingerprints. Before/after variants
+retain their own contexts while keeping scenario permissions and model
+parameters paired. Captured source is data and is never executed.
+
+The suite includes an unchanged playlist request, synthetic coastal-planning
+paraphrases, a short question, explicit research requirements, neutral false Web
+selection, authorized documents and agents, saved preferences, and direct-answer
+controls. Controlled completions establish
+application behavior, not improved live model judgment. Live paired evaluation
+requires an explicitly selected deployment and call budget; it is not performed
+by ordinary regression tests.

+# Orchestration reasoning-level compatibility
+
+**Version: 0.261.104**
+
+**Fixed in version: 0.261.104**, tracked by `VERSION` in
+`application/single_app/config.py`.
+
+## Issue and root cause
+
+Plan edits could fail while Auto or Review -> Run failed during answer generation.
+The selected GPT-5.6 Luna deployment rejected `reasoning_effort="minimal"` and
+reported the supported levels as None, Low, Medium, High, and XHigh.
+
+Both interfaces used outdated family-based reasoning choices. The V2 picker also
+inferred support from a preference key that could be an opaque model UUID.
+Orchestration passed the unsupported level to the provider. Initial planning
+concealed its failure with a direct-answer fallback, whereas editing correctly
+kept the previous plan. Ordinary chat appeared to work because it retried without
+the effort parameter; that did not mean Minimal had been honored.
+
+## Runtime policy
+
+`static/json/model_capabilities.json` now carries additive reasoning policies.
+`functions_model_capabilities.py` resolves the allowed levels from authorized
+canonical model metadata and declared aliases, independently of preference IDs.
+Existing non-reasoning and vision capability records are preserved.
+
+| Request | Effective behavior |
+| --- | --- |
+| Supported explicit level | Send it unchanged, including literal `none`. |
+| Unsupported level on a known model | Use its supported application default and show the correction. Luna Minimal becomes Low. |
+| No requested level | Omit the parameter; report model default. |
+| Unsupported or unknown reasoning support | Do not invent allowed levels. Omit the parameter and explain any discarded explicit choice. |
+| Provider rejects `reasoning_effort` | Retry once without that parameter only for the specific SDK HTTP 400 parameter/code rejection. Preserve the model and other valid arguments. |
+| Other provider failure | Propagate the failure; do not disguise it as compatibility recovery. |
+
+Low is the application's preferred supported fallback, not a claim about the
+provider's default. Model-default mode does not assert which effort the provider
+actually used.
+
+`model_endpoint_clients.py`, `functions_orchestration_models.py`, and
+`route_backend_chats.py` share this policy. A dedicated planner override keeps its
+own policy instead of inheriting the answer model's effort. JSON-format recovery
+is separate and only handles a rejected `response_format`.
+If both parameters are rejected, the binding remembers the reasoning omission
+before attempting recovery. A later JSON-format retry does not resend the
+rejected effort or reset its retry allowance. Model-default metadata survives
+even when the intermediate retry raises; a different explicit per-call effort
+retains its independent policy.
+
+## User-visible behavior and persistence
+
+V2 and classic selectors receive safe `reasoning_capabilities` metadata from
+`route_frontend_chats.py`. They retain the existing preference keys and merge
+corrected selections after preferences load rather than replacing unrelated
+model preferences.
+
+Live updates are merged by model and stage before filtering notices. A later
+resolution with no adjustment clears that stage's obsolete warning without
+removing a separate planner or answer correction.
+
+Corrections appear in the composer or relevant plan/answer surface. Saved message
+and run metadata distinguish:
+
+| Field | Meaning |
+| --- | --- |
+| `requested_reasoning_effort` | The original requested level. |
+| `reasoning_effort` | The effective explicit level, or null for model default. |
+| `reasoning_mode` | `explicit` or `model_default`. |
+| `reasoning_adjustments` | Safe requested/effective values, reason, canonical model name, and planner/answer stage. |
+
+The orchestration events, editor publication, and hydration projections preserve
+these notices. Display metadata does not rewrite immutable historical plans, add
+fake revisions, retarget models, or alter approval and concurrency rules. A
+failed edit still leaves the previous valid plan intact. Initial planning now
+also reports failures instead of manufacturing a successful direct-answer plan.
+
+## Validation and limitations
+
+Canonical policy and provider-error behavior are covered by
+`functional_tests/test_model_reasoning_capability_resolution.py` and
+`functional_tests/test_orchestration_model_selection.py`. Ordinary streaming and
+non-streaming paths are covered by `test_chat_reasoning_runtime.py`; empty-stream
+recovery has separate regression coverage. Combined reasoning/JSON rejection
+cases exercise both retry orders and require no more than three requests, with
+unchanged model identity, messages, and completion budget.
+
+`ui_tests/test_v2_reasoning_controls.py` exercises real composer behavior.
+`ui_tests/test_v2_orchestration_plan_editor_backend.py` forwards browser requests
+to the real Flask handlers, including stale Luna Minimal, a Web Search edit, and
+Run. Provider and storage boundaries are deterministic; these are not live
+model-quality evaluations.
+
+No API-version migration or Azure configuration change is required. The code
+must still be deployed before an existing hosted application gains this fix.

+    *   Every Orchestrate request reaches the planner, including short questions. Direct answers remain available; no topic rule forces research. Model and discovery failures are surfaced instead of becoming successful answer-only plans.
+    *   Fixed authorized group-agent catalog discovery and preserved original selections separately from model-chosen plan usage. Current capabilities are rechecked before execution.
+    *   Enabled saved memories now inform private-conversation planning, edits, and answers without autosave or embedding backfill. Scope and audience are rechecked before answering, and existing memory citations are preserved.

+## Orchestration context
+
+Since **0.261.104**, private-conversation orchestration also recalls enabled saved
+instructions and relevant embedded facts when planning, editing a plan, and
+answering. This automatic context is read-only; it does not require assigning
+the action to an agent and does not autosave or backfill memory embeddings.
+Current requests override saved preferences. Scope and membership are rechecked
+before answering, and memory provenance remains available in citations.
+
+Shared conversations, including their hidden backing records, do not receive
+this automatic memory context. See the
+[orchestration memory boundaries](https://github.com/microsoft/simplechat/blob/main/docs/explanation/fixes/ORCHESTRATION_CAPABILITY_CONTEXT_FIX.md#read-only-saved-memory)
+for scope selection and missing-embedding behavior.

+In Orchestrate, selected Document Search, Web Search, Deep Research, and eligible
+URL Access controls are positive requirements, not the complete list of permitted
+tools. Unchecked controls are neutral. The planner may choose other enabled,

+selecting Web Search. Image generation is unsupported in this mode and must be

+acknowledgment. The planner may choose a direct answer; no topic rule forces

 information before it can plan the request. They use the composer's editing capabilities

+Uses real Flask routes, revisions, executor, adapters and the shared memory reader.
+Only storage, membership, embedding and model boundaries are replaced. All network

-// Runtime test for the V2 per-model reasoning effort resolution.
-// Version: 0.261.036
-// Implemented in: 0.261.036
-//
-// The companion test, test_v2_reasoning_effort_persistence.py, asserts that the composer is
-// wired to the shared user setting and that the keys it writes are ones the route accepts.
-// Those are source assertions: they prove the pieces are connected, not that the right level
-// comes out.
-//
-// This file executes the resolution itself, because its failure modes are all silent. A level
-// stored under the wrong key is simply never found again. A stored level that the newly
-// selected model does not accept is sent and then stripped by the endpoint, so the user sees a
-// control claiming an effort that was never applied. And `none` is a real choice in the picker
-// but not a value the endpoint takes, so sending it looks like a working request.
-//
-// Run directly with `node functional_tests/test_v2_reasoning_effort_logic.mjs`. Requires Node
-// 22.6 or newer, which strips the TypeScript types so the real module can be imported rather
-// than a copy of it.
+// Version: 0.261.104

 """
-Functional test for V2 reasoning effort persistence.
+Functional regressions for canonical reasoning projection and preference contracts.
+Version: 0.261.104
+Implemented in: 0.261.104
 
-Version: 0.261.036
-Implemented in: 0.261.036
-
-The V2 reasoning level used to live only in the composer's local state. It was never read
-from or written to /api/user/settings, so it was lost on every remount -- navigating away
-and back, or reloading -- and it was never cleared when the model changed, which meant a
-level chosen for gpt-5 was still sent after switching to gpt-4o, a model that has no
-reasoning at all.
-
-The fix reuses the contract the classic interface already has rather than inventing a second
-one: the level is stored per model in the `reasoningEffortSettings` user setting, and the
-chosen model is stored in `preferredModelId` / `preferredModelDeployment`, which is what
-`_build_initial_chat_model_selection` restores the picker from.
-
-Three things are pinned here.
-
-**The keys have to be whitelisted.** /api/user/settings validates against `allowed_keys` in
-route_backend_users.py and drops anything outside it **without complaining** -- the POST
-still returns success and the value never arrives, so the preference appears to save and is
-gone on the next load.
-
-**The key a level is stored under has to match the classic interface.** Both write the same
-map, so `getCurrentModelName()` and `reasoningModelKey()` must agree on model id before
-deployment name. If they disagree, a level set in one interface is invisible in the other.
