### Task T018 - Run final validation

**Started**: 2026-06-26 16:29 **Completed**: 2026-06-26 16:31 **Duration**: 2 minutes

**Notes**:

* Ran the required focused validation command for mission artifact server tests, web helper/store tests, existing command-center store tests, Orchestration panel tests, all workspace typechecks, and root format check.
* Ran repository diff whitespace validation.
* Verified ASCII encoding and LF line endings across changed and new files.
* Captured final git status for handoff; `.spec_system/state.json` remained an existing modified file and was not reverted.

**Files Changed**:

* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T018 validation evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T018 complete and completed the session checklist.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- commandCenterMissionArtifacts missionArtifacts commandCenterStore OrchestrationPanel && npm run typecheck --workspaces --if-present && npm run format:check`
  * Result: PASS - focused tests, workspace typechecks, and root format check passed.
  * Evidence: Output reported 4 test files and 25 tests passed, all workspace `tsc` commands passed, and Biome format checked 699 files with no fixes applied.
* Command/check: `git diff --check`
  * Result: PASS - no whitespace errors reported.
  * Evidence: Command exited 0 with no output.
* Command/check: `while IFS= read -r file; do [ -f "$file" ] || continue; if LC_ALL=C grep -nP '[^\\x00-\\x7F]' "$file"; then bad=1; fi; done < <((git diff --name-only; git ls-files --others --exclude-standard) | sort -u); exit ${bad:-0}`
  * Result: PASS - no non-ASCII characters reported in changed/new files.
  * Evidence: Command exited 0 with no output.
* Command/check: `while IFS= read -r file; do [ -f "$file" ] || continue; if grep -n $'\\r' "$file"; then bad=1; fi; done < <((git diff --name-only; git ls-files --others --exclude-standard) | sort -u); exit ${bad:-0}`
  * Result: PASS - no CRLF line endings reported in changed/new files.
  * Evidence: Command exited 0 with no output.
* UI product-surface check: PASS - focused Orchestration panel tests cover artifact product copy and absence of debug/scaffolding labels.
* UI craft check: PASS - focused Orchestration panel tests cover accessible artifact region/buttons/dialogs and linked drawer navigation.

**BQC Fixes**:

* Final validation confirms duplicate-trigger guards, stale-selection cleanup, malformed frame rejection, raw-content blocking, route validation, attention side effects, and accessible artifact UI coverage remain green.

### Task T017 - Add Orchestration panel mission artifact tests

**Started**: 2026-06-26 16:25 **Completed**: 2026-06-26 16:29 **Duration**: 4 minutes

**Notes**:

* Added direct Mission Artifacts panel state coverage for loading, error, offline, disconnected, and empty states with product-facing copy.
* Added mounted Orchestration panel coverage for hydrated workpad, evidence, verification, and review-gate records in the Campaigns tab.
* Added drawer coverage for opening an evidence artifact, rendering linked artifact details, and navigating from the evidence drawer to a linked workpad drawer.
* Kept duplicate in-flight coverage through the existing guarded-action approval test in the same Orchestration panel suite because the artifact panel has no mutation buttons.

**Files Changed**:

* `apps/web/tests/OrchestrationPanel.test.tsx` - added Mission Artifacts panel state and mounted drawer-detail tests.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T017 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T017 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- OrchestrationPanel --run`
  * Result: PASS - Orchestration panel test suite passed.
  * Evidence: Output reported `apps/web/tests/OrchestrationPanel.test.tsx (13 tests)` passed.
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/tests/OrchestrationPanel.test.tsx apps/web/src/components/orchestration/MissionArtifactsPanel.tsx apps/web/src/components/orchestration/OrchestrationDrawer.tsx`
  * Result: PASS - focused Biome check passed after assertion wrapping.
  * Evidence: Output reported `Checked 3 files in 8ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* UI product-surface check: PASS - tests assert artifact states and records use product-facing copy and do not render debug/scaffolding labels.
* UI craft check: PASS - tests assert accessible region, buttons, modal dialog, linked drawer navigation, and existing duplicate in-flight control behavior remains covered.

**BQC Fixes**:

* Product surface discipline: panel tests cover loading, error, offline, disconnected, empty, hydrated record, blocked-label, and drawer-detail states without debug copy (`apps/web/tests/OrchestrationPanel.test.tsx`).
* Accessibility and platform compliance: tests use accessible region, button, and dialog queries for the mounted artifact panel and drawer (`apps/web/tests/OrchestrationPanel.test.tsx`).

***

### Task T016 - Add web mission artifact helper and store tests

**Started**: 2026-06-26 16:22 **Completed**: 2026-06-26 16:25 **Duration**: 3 minutes

**Notes**:

* Added helper tests for mission artifact progress chips, linked record ordering, blocked raw-content labels, and empty panel view state.
* Added store reducer tests for partial workpad event merging, delete-event stale drawer cleanup, verification/review-gate reconciliation, and separate verification/review counts.
* Added malformed artifact WebSocket frame coverage through `parseServerEventFrame` to ensure raw evidence payload fields are dropped before reducers can blank existing state.
* Kept fixtures protocol-valid with `test_result` evidence kind and safe repo-relative source paths.

**Files Changed**:

* `apps/web/tests/missionArtifacts.test.ts` - added web mission artifact helper and command-center store reducer tests.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T016 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T016 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- missionArtifacts --run`
  * Result: PASS - mission artifact tests passed; the filter also ran the server artifact test file.
  * Evidence: Output reported `apps/web/tests/missionArtifacts.test.ts (4 tests)` and `apps/server/tests/commandCenterMissionArtifacts.test.ts (2 tests)` passed.
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/tests/missionArtifacts.test.ts apps/web/src/lib/missionArtifacts.ts apps/web/src/store/useGameStore.ts`
  * Result: PASS - focused Biome check passed.
  * Evidence: Output reported `Checked 3 files in 18ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* UI product-surface check: N/A - helper/store tests only.
* UI craft check: N/A - helper/store tests only.

**BQC Fixes**:

* Failure path completeness: malformed artifact frames with raw fields are rejected before reducer application, preserving existing artifact state (`apps/web/tests/missionArtifacts.test.ts`).
* State freshness on re-entry: store tests assert partial artifact updates preserve existing records and delete events clear stale drawer selections (`apps/web/tests/missionArtifacts.test.ts`).

***

### Task T015 - Add server mission artifact tests

**Started**: 2026-06-26 16:15 **Completed**: 2026-06-26 16:22 **Duration**: 7 minutes

**Notes**:

* Added focused server coverage for workpad metadata writes, evidence metadata writes, failed verification attention creation, verification retry, retry-limit conflicts, verification skip, review-gate transitions, and review attention resolution.
* Added route and WebSocket coverage for nested workpad/evidence/verification/review mutation envelopes, verification retry duplicates, review decisions, compact artifact update frames, attention frames, and blocked raw payload errors.
* Fixed `parseMutationBody` so command-center mutation routes accept both existing direct DTO bodies and the web client's `{ item, expectedRevision?, idempotencyKey? }` envelope while still rejecting blocked raw fields at the envelope boundary.
* Kept assertions focused on safe metadata and verified route responses/events do not echo raw secrets or broad local paths.

**Files Changed**:

* `apps/server/tests/commandCenterMissionArtifacts.test.ts` - added manager and route/WebSocket tests for mission artifact behavior.
* `apps/server/src/lib/commandCenterValidation.ts` - accepted nested mutation envelopes for command-center mutation routes and retained blocked-field rejection.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T015 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T015 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- commandCenterMissionArtifacts --run`
  * Result: PASS - new mission artifact server tests passed.
  * Evidence: Output reported `apps/server/tests/commandCenterMissionArtifacts.test.ts (2 tests)` passed.
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- commandCenterValidation --run`
  * Result: PASS - existing command-center validation tests still passed after mutation envelope parser change.
  * Evidence: Output reported `apps/server/tests/commandCenterValidation.test.ts (3 tests)` passed.
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/server/src/lib/commandCenterValidation.ts apps/server/tests/commandCenterMissionArtifacts.test.ts`
  * Result: PASS - focused Biome check passed.
  * Evidence: Output reported `Checked 2 files in 10ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compile passed.
  * Evidence: Output reported `tsc --noEmit` with exit code 0.
* UI product-surface check: N/A - server tests and validation only.
* UI craft check: N/A - server tests and validation only.

**BQC Fixes**:

* Contract alignment: mutation routes now accept the nested envelope sent by the web command-center client while preserving the existing direct DTO compatibility path (`apps/server/src/lib/commandCenterValidation.ts`).
* Failure path completeness: tests cover retry-limit conflicts, blocked raw payload validation, duplicate retry idempotency, compact WebSocket updates, and attention side effects (`apps/server/tests/commandCenterMissionArtifacts.test.ts`).

***

### Task T014 - Document package mission artifact behavior

**Started**: 2026-06-26 16:14 **Completed**: 2026-06-26 16:15 **Duration**: 1 minute

**Notes**:

* Documented that server mission artifact ownership stays inside `orchestrationCommandCenter.ts`.
* Documented workpad/evidence writes, verification retry/skip, review decisions, retry limits, stale revision checks, duplicate-trigger guards, and attention side effects at the server package level.
* Documented that the web Mission Artifacts panel renders compact artifact metadata with loading, empty, error, offline, disconnected, linked-record, progress-chip, blocked-label, and drawer-detail states.
* Documented web artifact event reducer reconciliation and stale drawer-selection cleanup.

**Files Changed**:

* `apps/server/README_server.md` - documented server-owned mission artifact metadata routes and raw-content boundary.
* `apps/web/README_web.md` - documented Mission Artifacts panel behavior and artifact reducer reconciliation.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T014 evidence.

  * Result: PASS - no non-ASCII characters reported.
  * Evidence: Command exited with no matches.
* UI product-surface check: N/A - documentation only.
* UI craft check: N/A - documentation only.

**BQC Fixes**:

* Contract alignment: package docs now describe the server manager boundary, artifact action routes, and web artifact panel expectations (`apps/server/README_server.md`, `apps/web/README_web.md`).
* Product surface discipline: web package docs now explicitly block broad artifact surfaces from rendering raw evidence contents or unsafe local payloads (`apps/web/README_web.md`).

***

### Task T013 - Document mission artifact API routes

**Started**: 2026-06-26 16:12 **Completed**: 2026-06-26 16:14 **Duration**: 2 minutes

**Notes**:

* Added API reference rows for workpad metadata writes, evidence metadata writes, verification retry, verification skip, and review-gate decisions.
* Documented expected revision, idempotency, retry-limit, decision, and attention-update behavior for the new action routes.
* Added a command-center artifact privacy note explaining that blocked raw field names are rejected and accepted records can carry labels but not raw material.
* Added a WebSocket note for artifact update frames, including linked review gates inside verification frames and the raw-content exclusion boundary.

**Files Changed**:

* `docs/api/README_api.md` - documented local mission artifact REST routes, WebSocket metadata frames, and raw-content blocking.

  * Result: PASS - no non-ASCII characters reported.
  * Evidence: Command exited with no matches.
* UI product-surface check: N/A - documentation only.
* UI craft check: N/A - documentation only.

**BQC Fixes**:

* Trust boundary clarity: API docs now state that mission artifact routes reject blocked raw field names and only expose blocked-category labels for broad surfaces (`docs/api/README_api.md`).
* Contract alignment: route docs now describe verification retry/skip, review decisions, attention updates, and linked review gates in verification WebSocket frames (`docs/api/README_api.md`).

***

### Task T012 - Reconcile artifact updates in the command-center store

**Started**: 2026-06-26 16:08 **Completed**: 2026-06-26 16:12 **Duration**: 4 minutes

**Notes**:

* Added a normalized event merge helper for command-center artifact collections so WebSocket changes reconcile by id instead of replacing previously loaded records.
* Kept hydrate methods authoritative snapshots while making workpad, evidence, verification, and review-gate event reducers resilient to partial update frames.
* Updated verification events to normalize verification attempts and linked review gates as separate collections rather than applying the combined event count to both families.
* Preserved stale drawer cleanup by routing merged collections through the existing `commandCenterWithEventCollection` selection cleanup path.

**Files Changed**:

* `apps/web/src/store/useGameStore.ts` - added artifact event merge normalization and wired artifact event reducers through it.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T012 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T012 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/src/store/useGameStore.ts`
  * Result: PASS - focused Biome check passed after indentation cleanup.
  * Evidence: Output reported `Checked 1 file in 17ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* Command/check: Targeted code inspection of `apps/web/src/store/useGameStore.ts`
  * Result: PASS - artifact events merge incoming records, delete by changed id, normalize linked review gates separately, and retain existing stale selection cleanup.
  * Evidence: `normalizeCommandCenterEventCollection`, `mergeCommandCenterEventItems`, and artifact event cases inspected.
* UI product-surface check: N/A - no rendered UI copy changed.
* UI craft check: N/A - no rendered UI layout changed.

**BQC Fixes**:

* State freshness on re-entry: stale artifact drawer selections continue to close after merged event collections remove the selected id (`apps/web/src/store/useGameStore.ts`).
* Failure path completeness: partial artifact events preserve existing normalized records instead of blanking workpad, evidence, verification, or review-gate panels (`apps/web/src/store/useGameStore.ts`).

***

### Task T011 - Add artifact mutation clients

**Started**: 2026-06-26 16:05 **Completed**: 2026-06-26 16:07 **Duration**: 2 minutes

**Notes**:

* Added typed web API clients for workpad writes, evidence writes, verification retry, verification skip, and review-gate decisions.
* Expanded the generic command-center mutable family map to include workpads and evidence.
* Reused existing `requestCommandCenterMutation` in-flight guards, route-id validation, idempotency fields, refresh callbacks, timeout handling, and compact failure mapping.
* Added bounded invalid-reference responses for mission artifact action clients.

**Files Changed**:

* `apps/web/src/lib/orchestrationApi.ts` - added mission artifact mutation/action API clients and mutable family entries.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T011 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T011 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/src/lib/orchestrationApi.ts`
  * Result: PASS - focused Biome check passed.
  * Evidence: Output reported `Checked 1 file in 15ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* Command/check: `rg -n "recordCommandCenterWorkpad|recordCommandCenterEvidence|retryCommandCenterVerification|skipCommandCenterVerification|decideCommandCenterReviewGate|CommandCenterVerificationRetryInput|CommandCenterReviewGateDecisionInput|workpads:|evidence:" apps/web/src/lib/orchestrationApi.ts`
  * Result: PASS - new clients, types, mutable map entries, and parsers found.
  * Evidence: Output located all artifact client exports and workpad/evidence map entries.
* UI product-surface check: N/A - no rendered UI changed.
* UI craft check: N/A - no rendered UI changed.

**BQC Fixes**:

* Duplicate action prevention: artifact clients use existing in-flight mutation keys through `requestCommandCenterMutation` and send idempotency keys when provided (`apps/web/src/lib/orchestrationApi.ts`).
* Failure path completeness: invalid artifact route ids return caller-visible `invalid_input` failures before network calls (`apps/web/src/lib/orchestrationApi.ts`).

***

### Task T010 - Extend command-center drawer with linked artifact details

**Started**: 2026-06-26 16:03 **Completed**: 2026-06-26 16:05 **Duration**: 2 minutes

**Notes**:

* Added linked artifact detail rendering to the command-center drawer using the safe mission artifact helper.
* Added linked record rows for workpads, evidence, verification attempts, and review gates, excluding the currently selected record.
* Added optional drawer selection support so linked artifact rows can open their own command-center records.
* Kept drawer detail rows to safe metadata, state labels, target labels, and blocked raw-content labels only.

**Files Changed**:

* `apps/web/src/components/orchestration/OrchestrationDrawer.tsx` - added linked artifact detail section and selection handling.
* `apps/web/src/components/orchestration/OrchestrationShell.tsx` - passed command-center detail selection callback into the drawer.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T010 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T010 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/src/components/orchestration/OrchestrationDrawer.tsx apps/web/src/components/orchestration/OrchestrationShell.tsx`
  * Result: PASS - focused Biome check passed after formatting.
  * Evidence: Output reported `Checked 2 files in 8ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* Command/check: Targeted code inspection of `apps/web/src/components/orchestration/OrchestrationDrawer.tsx`
  * Result: PASS - linked artifact details render safe summaries and blocked labels only.
  * Evidence: `ArtifactDetails` and `buildDrawerArtifactDetails` inspected.
* UI product-surface check: PASS - drawer copy is product-facing and contains no debug/runtime/scaffolding labels.
* UI craft check: PASS - drawer details use existing modal semantics, close behavior, focus styles, compact rows, and text-fit utilities.

**BQC Fixes**:

* State freshness on re-entry: drawer already closes stale selections; linked artifact rows reuse current normalized collections and open fresh selections through the store (`apps/web/src/components/orchestration/OrchestrationDrawer.tsx`).
* Product surface discipline: linked details show safe metadata and blocked labels, never raw evidence content (`apps/web/src/components/orchestration/OrchestrationDrawer.tsx`).

***

### Task T009 - Wire Mission Artifacts into Orchestration panes

**Started**: 2026-06-26 16:02 **Completed**: 2026-06-26 16:03 **Duration**: 1 minute

**Notes**:

* Mounted `MissionArtifactsPanel` in the campaigns pane after the campaign and queue workbench.
* Passed normalized command-center workpad, evidence, verification, and review-gate collections into the panel.
* Preserved existing related-record groups for artifact families while adding a dedicated artifact surface.
* Passed connected, offline, loading, error, and selection callbacks through existing Orchestration pane state.

**Files Changed**:

* `apps/web/src/components/orchestration/CommandCenterPanes.tsx` - wired the Mission Artifacts panel into the campaigns pane.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T009 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T009 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/src/components/orchestration/CommandCenterPanes.tsx apps/web/src/components/orchestration/MissionArtifactsPanel.tsx apps/web/src/lib/missionArtifacts.ts`
  * Result: PASS - focused Biome check passed.
  * Evidence: Output reported `Checked 3 files in 6ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* Command/check: Targeted code inspection of `apps/web/src/components/orchestration/CommandCenterPanes.tsx`
  * Result: PASS - campaigns pane now renders `MissionArtifactsPanel` with artifact collections and existing `onSelect`.
  * Evidence: New panel mount inspected.
* UI product-surface check: PASS - source inspection confirms mounted copy is product-facing local artifact state and does not expose diagnostics, raw payloads, or scaffolding labels.
* UI craft check: PASS - panel uses existing Orchestration `PanelSection`, `StatusPill`, responsive grid, focus styles, and text-fit utilities.

**BQC Fixes**:

* Product surface discipline: artifact records now have a dedicated panel instead of relying on generic implementation-flavored collection lists (`apps/web/src/components/orchestration/CommandCenterPanes.tsx`).

***

### Task T008 - Create the Mission Artifacts panel

**Started**: 2026-06-26 16:00 **Completed**: 2026-06-26 16:02 **Duration**: 2 minutes

**Notes**:

* Added a Mission Artifacts panel component that renders workpad, evidence, verification, and review-gate records through the safe web view-model helper.

* Command/check: Targeted code inspection of `apps/web/src/components/orchestration/MissionArtifactsPanel.tsx`
  * Result: PASS - component includes loading, empty, error, offline, disconnected, linked-record, and blocked-label rendering paths.
  * Evidence: `MissionArtifactsPanel` and `MissionArtifactRow` inspected.
* UI product-surface check: N/A - component is not mounted in a route until T009.
* UI craft check: N/A - component is not mounted in a route until T009.

**BQC Fixes**:

* Accessibility and platform compliance: linked records render as buttons with accessible labels and visible focus styles (`apps/web/src/components/orchestration/MissionArtifactsPanel.tsx`).
* Product surface discipline: panel copy describes artifact state and local availability, not implementation diagnostics (`apps/web/src/components/orchestration/MissionArtifactsPanel.tsx`).

### Task T007 - Add bounded parsers for artifact action bodies and route ids

**Started**: 2026-06-26 15:55 **Completed**: 2026-06-26 16:00 **Duration**: 5 minutes

**Notes**:

* Added parser entry points for verification retry, verification skip, and review-gate decision request bodies.
* Added route id validators for verification and review-gate action routes.
* Added bounded optional retry-limit parsing and reused shared blocked-payload rejection, revision, idempotency, timestamp, audit, and summary normalization.
* Kept parser outputs separate from manager defaults so routes can add local-operator audit fallback at the action boundary.

**Files Changed**:

* `apps/server/src/lib/commandCenterValidation.ts` - added artifact action parsers, route id validators, and bounded retry-limit helper.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T007 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T007 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm test -- commandCenterValidation --run`
  * Result: PASS - focused validation test file passed.
  * Evidence: Vitest reported `apps/server/tests/commandCenterValidation.test.ts (3 tests)` and `Test Files 1 passed`.
* Command/check: `rg -n "parseVerificationRetryBody|parseVerificationSkipBody|parseReviewGateDecisionBody|validateCommandCenterVerificationRouteId|validateCommandCenterReviewGateRouteId|optionalPositiveInteger" apps/server/src/lib/commandCenterValidation.ts`
  * Result: PASS - parser and validator entry points found.
  * Evidence: Output located retry, skip, review decision parsers, route id validators, and bounded integer helper.
* UI product-surface check: N/A - no UI code changed.
* UI craft check: N/A - no UI code changed.

**BQC Fixes**:

* Trust boundary enforcement: action bodies reject blocked raw payload fields and validate revisions, idempotency keys, timestamps, audit refs, and bounded text before route handlers mutate state (`apps/server/src/lib/commandCenterValidation.ts`).
* Error information boundaries: parser failures use existing compact invalid-request responses rather than surfacing internal parser details (`apps/server/src/lib/commandCenterValidation.ts`).

### Task T006 - Create web mission artifact view-model helpers

**Started**: 2026-06-26 15:57 **Completed**: 2026-06-26 16:00 **Duration**: 3 minutes

**Notes**:

* Added pure web helpers for mission artifact panel view models, progress chips, linked records, safe summaries, target labels, and blocked raw-content labels.
* Supported both full REST records and compact WebSocket event entries for workpads, evidence, verification attempts, and review gates.
* Kept summaries bounded to known safe metadata fields and turned blocked categories into product-facing labels rather than raw content.
* Added target matching and linked evidence resolution through workpad evidence ids and verification evidence ids.

**Files Changed**:

* `apps/web/src/lib/missionArtifacts.ts` - created web mission artifact view-model helper module.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T006 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T006 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/web/src/lib/missionArtifacts.ts`
  * Result: PASS - focused Biome check passed after formatting.
  * Evidence: Output reported `Checked 1 file in 6ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/web run typecheck`
  * Result: PASS - web TypeScript build passed.
  * Evidence: Output reported `tsc -b --noEmit` with exit code 0.
* Command/check: Targeted code inspection of `apps/web/src/lib/missionArtifacts.ts`
  * Result: PASS - helper emits progress chips, linked records, safe summaries, and blocked labels without exposing raw artifact content.
  * Evidence: `buildMissionArtifactPanelView`, `buildMissionArtifactProgressChips`, `buildMissionArtifactLinkedRecords`, and `blockedRawContentLabel` inspected.
* UI product-surface check: N/A - no rendered UI surface changed.
* UI craft check: N/A - no rendered UI surface changed.

**BQC Fixes**:

* Product surface discipline: helper returns product-facing labels for blocked categories and safe summaries only (`apps/web/src/lib/missionArtifacts.ts`).
* Contract alignment: helper accepts both REST and WebSocket artifact record shapes already used by the normalized command-center store (`apps/web/src/lib/missionArtifacts.ts`).

### Task T005 - Wire mission artifact mutation and action routes

**Started**: 2026-06-26 15:55 **Completed**: 2026-06-26 15:57 **Duration**: 2 minutes

**Notes**:

* Added POST routes for workpad and evidence artifact writes using existing mutation envelopes.
* Added verification retry and skip routes with id route validation, in-flight duplicate protection, schema-backed action body parsing, and manager action calls.
* Added review-gate decision route with id route validation, schema-backed body parsing, local-operator audit fallback, in-flight duplicate protection, and manager decision calls.
* Updated the generic mutation runner to emit bounded attention updates when artifact managers return an attention change.

**Files Changed**:

* `apps/server/src/routes/commandCenter.ts` - added artifact mutation/action routes and attention event emission for artifact side effects.
* `apps/server/src/lib/commandCenterValidation.ts` - added route action parsers and verification/review id validators needed by the new routes.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T005 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T005 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/server/src/routes/commandCenter.ts apps/server/src/lib/commandCenterValidation.ts`
  * Result: PASS - focused Biome check passed after formatting.
  * Evidence: Output reported `Checked 2 files in 11ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compile passed.
  * Evidence: Output reported `tsc --noEmit` with exit code 0.
* Command/check: `rg -n "command-center/workpads|command-center/evidence|verification/:id/retry|verification/:id/skip|review-gates/:id/decision|parseVerificationRetryBody|parseVerificationSkipBody|parseReviewGateDecisionBody|changes\\.attention" apps/server/src/routes/commandCenter.ts apps/server/src/lib/commandCenterValidation.ts`
  * Result: PASS - route and parser entry points found.
  * Evidence: Output located new workpad, evidence, retry, skip, review decision routes, parser functions, and attention event emission.
* UI product-surface check: N/A - no UI code changed.
* UI craft check: N/A - no UI code changed.

**BQC Fixes**:

* Trust boundary enforcement: artifact action routes parse and validate request bodies before reaching manager state (`apps/server/src/lib/commandCenterValidation.ts`).
* Duplicate action prevention: route-level in-flight mutation keys guard retry, skip, and review decision actions while manager idempotency handles replay (`apps/server/src/routes/commandCenter.ts`).
* Contract alignment: new routes reuse existing mutation envelopes, manager result shapes, and command-center WebSocket event builders (`apps/server/src/routes/commandCenter.ts`).

### Task T004 - Extend command-center manager with mission artifact helpers

**Started**: 2026-06-26 15:51 **Completed**: 2026-06-26 15:55 **Duration**: 4 minutes

**Notes**:

* Added manager action input types for verification retry, verification skip, and review-gate decisions.
* Extended manager mutation success metadata so artifact actions can report attention, workpad, evidence, verification, and review-gate changes alongside the primary change.
* Added verification retry handling with failed-only precondition, expected-revision checks, idempotency-key dedupe, collection capacity guard, retry-limit enforcement, deterministic next attempt ids, and failed-verification attention resolution.
* Added verification skip handling with stale-revision checks, idempotency-key dedupe, completed-at audit time, and failed-verification attention dismissal.
* Added review-gate decision handling with stale-revision checks, idempotency-key dedupe, pending-state enforcement, decision audit fields, and review attention resolution or blocked-state refresh.
* Updated verification and review saves to create bounded attention items for failed verification and open or blocked review gates.

**Files Changed**:

* `apps/server/src/managers/orchestrationCommandCenter.ts` - added artifact action methods and attention dedupe/resolution helpers.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T004 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T004 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/server/src/managers/orchestrationCommandCenter.ts`
  * Result: PASS - focused Biome check passed after formatting.
  * Evidence: Output reported `Checked 1 file in 17ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compile passed.
  * Evidence: Output reported `tsc --noEmit` with exit code 0.
* Command/check: `rg -n "retryVerificationAttempt|skipVerificationAttempt|decideReviewGate|withMissionArtifactAttention|upsertMissionArtifactAttention|resolveMissionArtifactAttention" apps/server/src/managers/orchestrationCommandCenter.ts`
  * Result: PASS - new manager action and attention helper methods are present.
  * Evidence: Output located retry, skip, review decision, attention upsert, and attention resolution methods.
* UI product-surface check: N/A - no UI code changed.
* UI craft check: N/A - no UI code changed.

**BQC Fixes**:

* Duplicate action prevention: retry, skip, and review decision methods use mutation locks and action-specific idempotency keys (`apps/server/src/managers/orchestrationCommandCenter.ts`).
* State freshness on re-entry: action methods enforce expected revisions and pending-state checks before mutating records (`apps/server/src/managers/orchestrationCommandCenter.ts`).
* Failure path completeness: action methods return compact not-found, conflict, stale-revision, duplicate-trigger, capacity, and retry-limit responses instead of silently ignoring invalid states (`apps/server/src/managers/orchestrationCommandCenter.ts`).

### Task T003 - Create mission artifact server helpers

**Started**: 2026-06-26 15:47 **Completed**: 2026-06-26 15:51 **Duration**: 4 minutes

**Notes**:

* Added pure server helpers for mission artifact payload validation, safe target links, progress chips, retry-limit decisions, attention trigger derivation, attention item creation, and compact error mapping.
* Kept helper behavior protocol-first by reusing shared target parsing, blocked raw field rejection, compact error creation, and safe command-center id generation.
* Added explicit retry cap handling with deterministic next-attempt ids and conflict responses for exhausted retry budgets.
* Added attention trigger support for failed verification, review gates, budget, stall, escalation, and stale revision states without reading raw artifact contents.

**Files Changed**:

* `apps/server/src/lib/missionArtifacts.ts` - created server helper module for artifact safety, metadata, retry limits, and attention triggers.
* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T003 evidence.
* `.spec_system/specs/phase19-session10-mission-artifacts/tasks.md` - marked T003 complete.

**Verification**:

* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npx biome check apps/server/src/lib/missionArtifacts.ts`
  * Result: PASS - focused Biome check passed after formatting.
  * Evidence: Output reported `Checked 1 file in 6ms. No fixes applied.`
* Command/check: `source "$HOME/.nvm/nvm.sh" && nvm use 26.2.0 >/dev/null && npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compile passed.
  * Evidence: Output reported `tsc --noEmit` with exit code 0.
* Command/check: Targeted code inspection of `apps/server/src/lib/missionArtifacts.ts`
  * Result: PASS - helper rejects blocked raw fields, returns compact validation/conflict/not-found errors, and keeps output to metadata labels/chips only.
  * Evidence: `validateMissionArtifactPayload`, `parseMissionArtifactTarget`, `checkMissionArtifactRetryLimit`, and `buildMissionArtifactAttentionItem` inspected.
* UI product-surface check: N/A - no UI code changed.
* UI craft check: N/A - no UI code changed.

**BQC Fixes**:

* Trust boundary enforcement: central helper validates target refs and rejects blocked raw fields before manager or route code consumes artifact action inputs (`apps/server/src/lib/missionArtifacts.ts`).
* Mutation safety: retry helper enforces bounded retries and deterministic idempotent attempt ids for later manager action paths (`apps/server/src/lib/missionArtifacts.ts`).

### Task T002 - Verify existing command-center artifact DTOs and parsers

**Started**: 2026-06-26 15:46 **Completed**: 2026-06-26 15:47 **Duration**: 1 minute

**Notes**:

* Confirmed protocol already defines artifact target kinds for `workpad`, `evidence`, `verification`, and `review_gate`.
* Confirmed protocol DTOs exist for `CommandCenterWorkpadRecord`, `CommandCenterEvidenceArtifact`, `CommandCenterVerificationAttempt`, and `CommandCenterReviewGate`.
* Confirmed WebSocket event DTOs exist for `command_center_workpad_update`, `command_center_evidence_update`, and `command_center_verification_update`.
* Confirmed parsers reject blocked raw fields, enforce safe repo-relative `sourcePath`, validate revisions, normalize id arrays, and bound summary strings.
* Identified the gap for this session: route/action request body parsers for artifact writes, verification retry/skip, and review decisions live outside the shared protocol and need server-side validation.

**Files Changed**:

* `.spec_system/specs/phase19-session10-mission-artifacts/implementation-notes.md` - added T002 evidence.

**Verification**:

* Command/check: `rg -n "Workpad|Evidence|Verification|Review|workpad|evidence|verification|reviewGate|review_gate|parse.*Artifact|command_center_.*update" packages/protocol/src/orchestrationCommandCenter.ts`
  * Result: PASS - protocol artifact contracts and parser locations found.
  * Evidence: Output located workpad, evidence, verification, and review gate DTOs, parser functions, enum guards, and update event types.
* Command/check: `sed -n '760,1260p' packages/protocol/src/orchestrationCommandCenter.ts`
  * Result: PASS - artifact DTO and event contracts inspected.
  * Evidence: File defines artifact records and event entries for workpads, evidence, verification attempts, and review gates.
* Command/check: `sed -n '3338,3568p' packages/protocol/src/orchestrationCommandCenter.ts`
  * Result: PASS - artifact parsers inspected.
  * Evidence: Parsers call `rejectCommandCenterBlockedPayloadFields`, revision/timestamp normalization, id array normalization, and safe path parsing.
* UI product-surface check: N/A - no UI code changed.
* UI craft check: N/A - no UI code changed.
