### Task T020 - Export executor components

**Started**: 2026-06-26 07:09 **Completed**: 2026-06-26 07:10 **Duration**: 1 minute

**Notes**:

* Exported the executor family panel and execution run-history drawer from the orchestration component index for stable imports.

**Files Changed**:

* `apps/web/src/components/orchestration/index.ts` - exported executor components.
* `.spec_system/specs/phase19-session06-executor-registry/implementation-notes.md` - logged T020 evidence.
* `.spec_system/specs/phase19-session06-executor-registry/tasks.md` - marked T020 complete.

**Verification**:

* Command/check: `rg -n "ExecutorFamiliesPanel|ExecutorRunHistoryDrawer" apps/web/src/components/orchestration/index.ts`
  * Result: PASS - Both executor components are exported.
  * Evidence: Output shows exports for `ExecutorFamiliesPanel` and `ExecutorRunHistoryDrawer`.
* UI product-surface check: N/A - export-only change.
* UI craft check: N/A - export-only change.

### Task T019 - Delegate execution-run drawer rendering

**Started**: 2026-06-26 07:06 **Completed**: 2026-06-26 07:09 **Duration**: 3 minutes

**Notes**:

* `OrchestrationDrawer` now delegates selected execution records to `ExecutorRunHistoryDrawer`.
* Existing generic command-center drawer behavior remains unchanged for all other record kinds.
* Generic drawer focus and Escape effects skip execution selections so the scoped run drawer owns its lifecycle.

**Files Changed**:

* `apps/web/src/components/orchestration/OrchestrationDrawer.tsx` - delegates execution selections to the scoped run drawer.
* `.spec_system/specs/phase19-session06-executor-registry/implementation-notes.md` - logged T019 evidence.
* `.spec_system/specs/phase19-session06-executor-registry/tasks.md` - marked T019 complete.

**Verification**:

* Command/check: `rg -n "ExecutorRunHistoryDrawer|selection.kind === \"executions\"|command-center-drawer" apps/web/src/components/orchestration/OrchestrationDrawer.tsx`
  * Result: PASS - Execution drawer delegation and existing generic drawer markup are present.
  * Evidence: Output shows the scoped drawer import/branch and generic drawer test ids.
* Command/check: `sed -n '1,70p' apps/web/src/components/orchestration/OrchestrationDrawer.tsx`
  * Result: PASS - Hook order is preserved and generic focus/Escape effects skip execution selections.
  * Evidence: Inspection shows hooks run before returns, with non-execution guards.
* UI product-surface check: PASS - Execution selections use scoped run copy, other command-center records keep the existing generic drawer.
* UI craft check: PASS - Focus and Escape ownership are not duplicated for execution run details.

**BQC Fixes**:

* State freshness on re-entry: Execution selections are delegated through the current selected record lookup and existing selection cleanup path (`apps/web/src/components/orchestration/OrchestrationDrawer.tsx`).
* Accessibility and platform compliance: Scoped execution drawer owns its focus and Escape lifecycle (`apps/web/src/components/orchestration/OrchestrationDrawer.tsx`).

  * Result: PASS - Panel, refresh handler, and run-selection wiring are present.
  * Evidence: Output lists panel import/rendering, shell probe call, pass-through props, and execution selection.
* Command/check: `rg -n "case \"executors\"|onSelect\\(\"executions\"" apps/web/src/components/orchestration/CommandCenterPanes.tsx`
  * Result: PASS - Executors tab routes run clicks to execution detail selection.
  * Evidence: Output shows the `executors` case and `onSelect("executions", id)`.
* UI product-surface check: PASS - Executors tab now shows product-facing executor posture instead of generic record lists.
* UI craft check: PASS - Refresh and run-selection controls are keyboard buttons with accessible labels from the panel.

**BQC Fixes**:

* Duplicate action prevention: Executor refresh uses the existing command-center mutation in-flight guard and client idempotency key helper (`apps/web/src/components/orchestration/OrchestrationShell.tsx`).

  * Result: PASS - Route persists execution runs and emits executor/execution updates.
  * Evidence: Output shows create, executing, complete, executor update, and execution update calls.
* Command/check: `sed -n '1,260p' apps/server/src/routes/guardedActions.ts`
  * Result: PASS - Route keeps validation, idempotent duplicates, and in-flight mutation locks around the approval path.
  * Evidence: Inspection shows validated route ids, parsed decision bodies, duplicate short-circuit, and `runMutation` cleanup in `finally`.
* UI product-surface check: N/A - server route code only.
* UI craft check: N/A - server route code only.

**BQC Fixes**:

* Failure path completeness: If command-center run creation fails, approval completes with a compact failed guarded-action result (`apps/server/src/routes/guardedActions.ts`).
* Concurrency safety: Route mutation lock covers the async registry execution path and clears in `finally` (`apps/server/src/routes/guardedActions.ts`).

***

### Task T009 - Update guarded-action approval logic for registry results

**Started**: 2026-06-26 06:38 **Completed**: 2026-06-26 06:42 **Duration**: 4 minutes

**Notes**:

* Changed approval to record an approved decision first instead of immediately claiming the hardcoded unavailable result.
* Added `completeApproval` so registry results can complete approved proposals as executed, failed, unavailable, or approved-not-executing.
* Preserved stale revision, duplicate decision, rejection, expiry, and mutation-lock behavior in the manager path.

**Files Changed**:

* `apps/server/src/managers/guardedActions.ts` - added approval completion and removed the fixed unavailable approval result.
* `apps/server/src/routes/guardedActions.ts` - routes approval through registry evaluation before completing the guarded action.
* `.spec_system/specs/phase19-session06-executor-registry/implementation-notes.md` - logged T009 evidence.
* `.spec_system/specs/phase19-session06-executor-registry/tasks.md` - marked T009 complete.

**Verification**:

  * Evidence: Output shows `completeApproval`, `stateForResult`, and approved state assignment.
* Command/check: `rg -n "completeApprovedAction|executorRegistry.evaluate" apps/server/src/routes/guardedActions.ts`
  * Result: PASS - Guarded-action route approval evaluates registry state before completion.
  * Evidence: Output shows route-level registry evaluation and completion helper.
* UI product-surface check: N/A - server approval code only.
* UI craft check: N/A - server approval code only.

**BQC Fixes**:

* Duplicate action prevention: Existing decision idempotency and mutation locks remain in the manager, while route-level in-flight locks wrap the registry completion path (`apps/server/src/managers/guardedActions.ts`, `apps/server/src/routes/guardedActions.ts`).
* Contract alignment: Guarded-action result state is now derived from registry result status instead of a fixed unavailable path (`apps/server/src/managers/guardedActions.ts`).

***

### Task T004 - Create executor registry entry and execution contracts

**Started**: 2026-06-26 06:28 **Completed**: 2026-06-26 06:31 **Duration**: 3 minutes

**Notes**:

* Added the executor registry boundary with entry types, guarded family/kind mapping, probe contracts, timeout policy, execute contract, and cleanup hook.
* Implemented timeout cleanup with `AbortController`, `clearTimeout`, and optional entry cleanup on scope exit.

**Files Changed**:

* `apps/server/src/managers/executorRegistry.ts` - created registry contracts, mapping helpers, timeout execution wrapper, and cleanup support.
* `.spec_system/specs/phase19-session06-executor-registry/implementation-notes.md` - logged T004 evidence.
* `.spec_system/specs/phase19-session06-executor-registry/tasks.md` - marked T004 complete.

**Verification**:

* Command/check: `rg -n "interface ExecutorRegistryEntry|guardedToExecutorKind|ExecutorExecutionContext|cleanup|timeoutMs|AbortController" apps/server/src/managers/executorRegistry.ts`
  * Result: PASS - Registry contracts, mapping, timeout, abort, and cleanup hooks are present.
  * Evidence: Output shows `ExecutorRegistryEntry`, `ExecutorExecutionContext`, `guardedToExecutorKind`, `timeoutMs`, `AbortController`, `clearTimeout`, and `entry.cleanup`.
* UI product-surface check: N/A - server registry code only.
* UI craft check: N/A - server registry code only.

**BQC Fixes**:

* Resource cleanup: Timeout handles are cleared and the abort controller is aborted in `finally`; optional entry cleanup runs on scope exit (`apps/server/src/managers/executorRegistry.ts`).

* Added a focused Vitest component scaffold naming executor cards, run-history drawer, offline and empty states, failed and executed states, and redaction coverage.
* Left assertions as todo cases until the executor panel and drawer implementation exists.

**Files Changed**:

* `apps/web/tests/ExecutorFamiliesPanel.test.tsx` - created executor panel test scaffold.
* `.spec_system/specs/phase19-session06-executor-registry/implementation-notes.md` - logged T003 evidence.
* `.spec_system/specs/phase19-session06-executor-registry/tasks.md` - marked T003 complete.

**Verification**:

* Command/check: `sed -n '1,80p' apps/web/tests/ExecutorFamiliesPanel.test.tsx`
  * Result: PASS - Scaffold exists with required case names.
  * Evidence: Test file declares family card, run-history drawer, offline/empty, failed/executed, and redaction todo cases.
* UI product-surface check: N/A - test scaffold only.
* UI craft check: N/A - test scaffold only.

## Task Log

### Task T021 - Update focused protocol-adjacent, server, web, and WebSocket tests

**Started**: 2026-06-26 06:52 **Completed**: 2026-06-26 07:01 **Duration**: 9 minutes

**Notes**:

* Replaced executor registry and executor panel todo scaffolds with executable Vitest coverage.
* Added server coverage for ready execution, non-ready repair guidance, bounded/redacted summaries, failure and timeout mapping, guarded approval completion, execution-run idempotency, executor probe routes, execution detail routes, diagnostics posture, and WebSocket approval event sequences.
* Wired WebSocket guarded-action approvals through the executor registry and command-center execution runs to match the REST approval path.
* Removed preview-summary fallback from command-center execution target labels so compact execution events do not carry guarded preview text.

### Task T001 - Verify prerequisite artifacts and guarded-action approval boundary

**Started**: 2026-06-26 06:26 **Completed**: 2026-06-26 06:26 **Duration**: 1 minute

**Notes**:

* Confirmed Session 05 validation report passed and documented the command-center attention and permission approval baseline.
* Confirmed the current guarded-action approval boundary still marks approved actions as unavailable through `unavailableResult`, which is the boundary this session replaces with registry-gated execution.
* Confirmed Node 26.2.0 is available through nvm for session checks even though the default shell node is v24.14.0.

**Files Changed**:

* `.spec_system/specs/phase19-session06-executor-registry/implementation-notes.md` - created session progress log and T001 evidence.
* `.spec_system/specs/phase19-session06-executor-registry/tasks.md` - marked T001 complete.

**Verification**:

* Command/check: `sed -n '1,260p' .spec_system/specs/phase19-session05-attention-and-permissions/validation.md`
  * Result: PASS - Session 05 validation result is PASS with 20/20 tasks complete and no blockers.
  * Evidence: Report confirms attention and permission state, stale/duplicate handling, redaction, local-only boundaries, and full-suite validation.

  * Result: PASS - Current guarded-action approvals still call the fixed unavailable path.
  * Evidence: `apps/server/src/managers/guardedActions.ts` sets approved proposals to `unavailable` and assigns `unavailableResult`.
* Command/check: `source "$NVM_DIR/nvm.sh" && nvm use 26.2.0 >/dev/null && node --version && npm --version`
  * Result: PASS - Required toolchain is available.
  * Evidence: Node `v26.2.0`, npm `11.16.0`.
