Summary

  • authenticate and deduplicate Discord Gateway events before any thread, session, workflow, or sandbox side effect
  • authorize every root, continuation, stop, and proposal approval against immutable actor/guild/channel/thread/role policy
  • add durable typed proposal, atomic approval, semantic notification, and idempotent Discord delivery primitives
  • reconcile a separate per-user execution principal and reject direct or unreviewed grants
  • mint GitHub App installation tokens for exact repository scopes and invalidate wider cached tokens when scope changes

Discord remains disabled by default. The organization overlay and infrastructure rollout gates will land separately.

Validation

  • Discord typecheck and full suite: 157 passed
  • Rust api-server, workflows, and iron-control suites: 327 passed
  • Python workflow-host suite: 40 passed
  • changed Ruby files compile under Ruby 3.4.8
  • frozen offline pnpm install and diff checks passed

Rails integration, chart rendering, and end-to-end production policy gates remain required CI/deployment checks before Discord can be enabled.


Note

High Risk
Changes span authentication, Discord authorization, iron-control principal/role reconciliation, and durable proposal approval paths—any bug could block ingress or approve the wrong mutation.

Overview
This PR wires Discord actor-scoped access and human-in-the-loop mutations through the control plane, Helm, and workflow runtime—not just the bot adapter.

Discord ingress and deployment replace the old trigger-role allowlist with reviewed roleBindings (plus optional triggerBotBindings and TTL/replay env). Enabling Discord now fails Helm render without guild/channel allowlists and a non-empty binding policy. api-rs gets Discord internal URL, approval-role allowlist, and actionProposalBindings; NetworkPolicies allow api-rs → discordbot:3001 for authenticated workflow delivery.

API auth and session metadata add a WorkflowApprovals capability for discordbot ingress only. Session create/append/execute strip or validate trusted Discord policy fields so audit records cannot spoof actor, scope, or thread identity. A new POST /api/workflows/proposals/{fingerprint}/approve route is restricted to authenticated Discord ingress.

Iron-control shifts policy-managed Discord sessions to per-user principals, atomically replace_principal_policy from the asserted reviewed role, and fail-closed on direct grants, unreviewed roles, or GitHub App scope mismatches. Discord policy errors map to 403.

Workflows v2 gains durable action proposals, approval claims, and semantic notification state (migrations + runtime hooks documented as put_action_proposal, transition_notification_state, post_to_discord). HTTP tool secrets can declare http_methods / paths for tighter iron-proxy rules.

The @chat-adapter/discord patch adds Gateway admission hooks, verified bot identity, safer outbound mentions, lock-conflict handling, and trimmed Gateway intents.

📝 Walkthrough

Walkthrough

The change adds policy-controlled Discord Gateway admission, actor-scoped sessions, workflow proposals, notification state, authenticated Discord delivery, HTTP request scoping, sandbox policy replacement, and repository-scoped GitHub App credentials.

Changes

Discord policy and workflow controls

Layer / File(s) Summary
Discord policy configuration and Gateway admission
contrib/chart/*, services/discordbot/src/*, patches/@chat-adapter__discord@4.31.0.patch
Discord ingress now uses validated role bindings, verified Gateway identity, durable admission records, actor checks, continuation checks, delivery fingerprints, and fail-closed rejection paths.
Actor-scoped sessions and workflow controls
services/discordbot/src/session-api.ts, services/discordbot/src/index.ts, services/api-rs/crates/centaur-api-server/*, services/api-rs/crates/centaur-iron-control/*, services/api-rs/crates/centaur-workflows/*, services/workflow-python/*, services/api-rs/crates/centaur-session-sqlx/migrations/*
Accepted Discord policy now flows into sessions and principals. The runtime supports canonical proposals, notification state, interruption, authenticated approval, and idempotent Discord delivery.

GitHub App repository scope

Layer / File(s) Summary
Repository scope persistence and token enforcement
services/console/app/*, services/console/db/*, services/console/lib/broker/*, services/console/test/*
Broker credentials now store exact repository allowlists. Validation, token refresh requests, response scope checks, API serialization, and rescoping behavior are covered.

HTTP secret request scoping

Layer / File(s) Summary
HTTP method and path restrictions
services/api-rs/crates/centaur-api-server/src/tool_discovery.rs, services/api-rs/crates/centaur-perms/*, services/console/app/services/credential_profiles/github_token.rb, tools/README.md
HTTP secrets now validate and preserve method and path restrictions in generated request rules.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to a3fc2

This PR adds actor-scoped Discord authorization, approvals, and internal workflow delivery, but the current implementation still permits a test-oriented emulation path to establish trusted identity without transport proof and leaves credential authentication and encryption requirements for internal delivery insufficiently enforced. An attacker or misconfigured deployment could bypass intended admission controls or expose delivery credentials, so these risks should be resolved or explicitly accepted before merge.

The partial index covers pending rows only. Consumed and expired rows stay in workflow_action_proposals forever, and each row holds the full proposal JSON plus Discord actor identifiers. Add a periodic delete or archive step for rows past a retention window, so table growth and retained Discord identifiers stay bounded.

Add a timeout and reuse the HTTP client for the Discord delivery call.

reqwest::Client::new() applies no request timeout. If discordbot accepts the connection and never responds, this await blocks the workflow context request for the lifetime of the task, and the Python workflow stalls with no error. The call also builds a new connection pool on every delivery.

Set an explicit timeout and share one client. Also include the response body in the error so the bot's delivery error code reaches the workflow log.

Inline comments:

- Around line 748-752: Update the Helm template handling discordbot.roleBindings
to explicitly fail rendering when discordbot.enabled is true and the
roleBindings list is empty; do not rely on required, which accepts an empty
non-nil list. Preserve the existing validated JSON generation for non-empty
bindings and place the check in the template logic that sets
DISCORDBOT_ROLE_BINDINGS_JSON.

In `@services/api-rs/crates/centaur-workflows/src/action_proposals.rs`:
- Line 548: Update approve_action_proposal to retain the normalized result from
sha256_fingerprint and use it for the subsequent FOR UPDATE lookup,
computed_fingerprint comparison, and approved-proposal idempotency key; do not
reuse the raw path fingerprint after validation.
- Around line 696-713: The repository validators must reject “.” and “..” as
owner or repository segments and share one validation rule to prevent drift.
Update exact_repository in
services/api-rs/crates/centaur-workflows/src/action_proposals.rs (lines 696-713)
and the corresponding validator in
services/api-rs/crates/centaur-api-server/src/routes.rs (lines 1020-1036) to
reuse the shared segment check alongside the existing character validation.

In `@services/discordbot/src/discord-allowlist.ts`:
- Line 241: The inert-status logic around configuredDiscordRoleIds and
resolveTriggerRoleAllowlist is inconsistent: empty roleBindings are reported as
incomplete while a legacy triggerRoleAllowlist can still admit users. Align
these behaviors by either disabling legacy-role fallback when policy bindings
are absent or removing the inert status for that state, and add coverage for
empty roleBindings with a configured legacy role.

In `@services/discordbot/src/discord-delivery.ts`:
- Line 63: Update the idempotency handling around isDeliveryResult to store and
compare a canonical fingerprint of the complete delivery request, including
text, channel_id, and delivery_id. Return the existing result only when the
fingerprint matches; otherwise reject the reused delivery_id with HTTP 409
before posting or overwriting the result.
- Around line 152-155: Validate the resolved Discord API base URL in
discord-delivery before any request is sent, rejecting non-HTTPS schemes. Apply
this consistently to every Discord API call that uses options.discordApiUrl,
including the apiBase construction path, while preserving the existing default
URL and trailing-slash normalization.

💡 Codex Review

if (!isDiscordPermissionError(error)) throw error;

P2 Badge Release the guild slot when context collection fails

If Discord history collection fails with a transient non-permission error after a root execution acquires its guild slot, this rethrow exits before any release path or the later execution try block is reached. Each such failure permanently consumes one in-memory slot, and after the configured maximum is exhausted every subsequent guild execution is demoted to append-only until the pod restarts; release the slot in an encompassing finally or acquire it after context collection.

💡 Codex Review


P1 Badge Rescan obligations skipped by a live lease

When the pod dies during a live render, its two-minute lease remains in Postgres; the replacement pod normally starts before that TTL expires, reaches this branch, and skips the obligation. Because the skip does not increment deferredCount, recoverRenderObligationsWithRetry sees zero deferred work and exits permanently, so the indexed execution is never rendered even after the stale lease expires. Count lease-skipped obligations as deferred so startup recovery rescans them.
