**Started**: 2026-06-26 01:59 **Completed**: 2026-06-26 01:59 **Duration**: 1 minute

**Notes**:

* Verified current route modules keep in-flight mutation locks local to the route module, delegate state ownership to managers, and emit compact broadcaster frames on accepted mutations.
* Verified manager patterns use bounded in-memory maps, idempotency indexes, revision checks, deterministic ordering, compact event entries, and conflict or not-found envelopes.
* Verified WebSocket hydration appends orchestration frames after base cockpit state through `sendOrchestrationHydration`.
* Verified diagnostics report bounded counts rather than raw manager payloads.

**Files Changed**:

* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded setup evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T002 complete after evidence was recorded.

### Task T004 - Implement bounded manager collections, counts, ordering, and snapshots

**Started**: 2026-06-26 02:02 **Completed**: 2026-06-26 02:05 **Duration**: 3 minutes

**Notes**:

* Added bounded in-memory maps for the command-center families: campaigns, tasks, attention, executors, hero lifecycle, executions, permissions, file intents, workpads, evidence, verification, review gates, handoffs, diagnostics, channels, usage, and notification readiness.
* Added deterministic list snapshots with `CommandCenterScopeFilters`, cursor support, stable sort modes, scope filtering, bounded limits, and cloned response items.
* Added compact count helpers and event-entry builders for each family so later REST and WebSocket code can emit minimal state without raw payload rows.

**Files Changed**:

* `apps/server/src/managers/orchestrationCommandCenter.ts` - expanded the manager with read-side collections, list snapshots, counts, deterministic ordering, and compact entries.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T004 complete after evidence was recorded.

  * Evidence: `tsc --noEmit` completed with exit code 0 after fixing timestamp union narrowing.
* Command/check: `rg -n "counts\\(|listCampaigns|eventCampaigns|MAX_COLLECTION_SIZE|defaultScope" apps/server/src/managers/orchestrationCommandCenter.ts`
  * Result: PASS - manager exposes bounded collections, list snapshots, compact counts, event entries, and default scope helpers.
  * Evidence: found `MAX_COLLECTION_SIZE`, `counts`, `list*` methods, `event*` methods, and `defaultScope`.
* UI product-surface check: N/A - server manager read-side implementation only.
* UI craft check: N/A - server manager read-side implementation only.

**BQC Fixes**:

* Contract alignment: replaced broad union timestamp narrowing with guarded string-field access so all snapshot sorting helpers typecheck under strict TypeScript (`apps/server/src/managers/orchestrationCommandCenter.ts`).

***

### Task T005 - Implement shared mutation metadata, revision checks, and duplicate prevention

**Started**: 2026-06-26 02:05 **Completed**: 2026-06-26 02:07 **Duration**: 2 minutes

**Notes**:

* Added shared command-center mutation result and input types.
* Added a generic `upsertRecord` path for all manager-owned families, including idempotency-key duplicate returns, stale expected-revision conflicts, collection capacity conflicts, and in-manager mutation locks.
* Added permission decision handling with decision idempotency, stale revision rejection, duplicate decision rejection, and compact change metadata.
* Added stale-state cleanup for expirable attention, file intent, handoff, and permission records.

**Files Changed**:

* `apps/server/src/managers/orchestrationCommandCenter.ts` - added mutation metadata, idempotency maps, in-flight locks, revision checks, permission decisions, and expiry cleanup.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T005 complete after evidence was recorded.

**Verification**:

  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0 after generic conflict-return fixes.
* Command/check: `rg -n "upsertRecord|withMutationLock|idempotencyKeys|checkExpectedRevision|cleanupExpired|decidePermission" apps/server/src/managers/orchestrationCommandCenter.ts`
  * Result: PASS - mutation metadata and duplicate-prevention paths are present.
  * Evidence: found shared upsert, lock, idempotency, stale revision, cleanup, and permission decision helpers.
* UI product-surface check: N/A - server manager mutation implementation only.
* UI craft check: N/A - server manager mutation implementation only.

**BQC Fixes**:

* Duplicate action prevention: added manager-level mutation locks plus idempotency-key replay handling (`apps/server/src/managers/orchestrationCommandCenter.ts`).
* State freshness on re-entry: added `cleanupExpired` so stale expirable records are reconciled before snapshots or diagnostics can consume them (`apps/server/src/managers/orchestrationCommandCenter.ts`).
* Failure path completeness: stale revision, duplicate key, in-flight, missing permission, and capacity paths return compact conflict or not-found envelopes (`apps/server/src/managers/orchestrationCommandCenter.ts`).

***

### Task T006 - Implement capability and unavailable envelope helpers

**Started**: 2026-06-26 02:07 **Completed**: 2026-06-26 02:09 **Duration**: 2 minutes

**Notes**:

* Seeded executor capability records from the protocol `COMMAND_CENTER_EXECUTOR_KIND_VALUES` and `COMMAND_CENTER_EXECUTOR_FAMILY_VALUES` lists.
* Added capability envelope and response helpers with docs paths, repair requirements, non-executing messages, and explicit unavailable reasons for non-ready executor families.
* Added capability refresh support that updates compact executor capability timestamps without executing any work.

**Files Changed**:

* `apps/server/src/managers/orchestrationCommandCenter.ts` - added capability seeding, envelopes, docs paths, requirements, unavailable reasons, and refresh helpers.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T006 complete after evidence was recorded.

  * Result: PASS - capability seeding and unavailable envelope helpers are present.
  * Evidence: found protocol value-list seeding, envelope helpers, unavailable reason mapping, and refresh capability logic.
* UI product-surface check: N/A - server capability scaffolding only.
* UI craft check: N/A - server capability scaffolding only.

**BQC Fixes**:

* Contract alignment: seeded capabilities directly from protocol executor kind/family values so new server state cannot silently drift from Session 01 contracts (`apps/server/src/managers/orchestrationCommandCenter.ts`).
* Product surface discipline: capability messages explicitly state scaffolded or non-executing status rather than implying file, git, terminal, container, remote, Worker, hosted, or channel execution is available (`apps/server/src/managers/orchestrationCommandCenter.ts`).

***

### Task T007 - Create route validation adapters for command-center inputs

**Started**: 2026-06-26 02:09 **Completed**: 2026-06-26 02:11 **Duration**: 2 minutes

**Notes**:

* Added `apps/server/src/lib/commandCenterValidation.ts` with scope query, route id, mutation metadata, and protocol parser adapters.
* Added validation wrappers for every command-center route body family used by this session.
* Mapped protocol parser failures and blocked raw payload fields to compact `invalid_request` responses without echoing raw request values.

**Files Changed**:

* `apps/server/src/lib/commandCenterValidation.ts` - added command-center query/body/id validation adapters and error mapping.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T007 complete after evidence was recorded.

**Verification**:

  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "parseCommandCenterScopeQuery|parseMutationBody|rejectCommandCenterBlockedPayloadFields|validateCommandCenterRouteId|parsePermissionDecisionMutationBody" apps/server/src/lib/commandCenterValidation.ts`
  * Result: PASS - validation adapters cover scope queries, mutation bodies, raw-field rejection, route IDs, and permission decisions.
  * Evidence: found the exported validation helpers and shared mutation parser.
* UI product-surface check: N/A - server validation implementation only.
* UI craft check: N/A - server validation implementation only.

**BQC Fixes**:

* Trust boundary enforcement: every command-center request body now crosses a protocol parser and raw-field blocklist before entering manager state (`apps/server/src/lib/commandCenterValidation.ts`).
* Error information boundaries: validation responses include compact field messages and do not echo raw prompts, commands, paths, terminal output, provider payloads, tokens, or secrets (`apps/server/src/lib/commandCenterValidation.ts`).

***

### Task T008 - Create compact command-center event builders

**Started**: 2026-06-26 02:11 **Completed**: 2026-06-26 02:12 **Duration**: 1 minute

**Notes**:

* Added manager-owned builders for every `command_center_*_update` event family.
* Added deterministic `hydrationEvents()` ordering for future WebSocket connection setup.
* Reused compact event-entry helpers so event frames include IDs, states/statuses, revisions, counts, safe relative paths, timestamps, and blocked-category labels only.

**Files Changed**:

* `apps/server/src/managers/orchestrationCommandCenter.ts` - added compact command-center update event builders and hydration frame ordering.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T008 complete after evidence was recorded.

**Verification**:

* Command/check: `npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "planUpdateEvent|executorUpdateEvent|verificationUpdateEvent|usageUpdateEvent|hydrationEvents|combinedCounts" apps/server/src/managers/orchestrationCommandCenter.ts`
  * Result: PASS - command-center event builders and deterministic hydration list are present.
  * Evidence: found representative event builders plus `hydrationEvents` and combined count support.
* UI product-surface check: N/A - server WebSocket event builder implementation only.
* UI craft check: N/A - server WebSocket event builder implementation only.

**BQC Fixes**:

* Contract alignment: event builders return the protocol `CommandCenterServerEvent` union and use the protocol compact entry shapes (`apps/server/src/managers/orchestrationCommandCenter.ts`).
* Error information boundaries: event builders use compact entry methods instead of broadcasting raw manager records (`apps/server/src/managers/orchestrationCommandCenter.ts`).

### Task T009 - Wire manager construction into server startup and dependency passing

**Started**: 2026-06-26 02:12 **Completed**: 2026-06-26 02:13 **Duration**: 1 minute

**Notes**:

* Constructed one `OrchestrationCommandCenterManager` during server startup.
* Passed the manager through diagnostics and WebSocket dependency objects so later route, diagnostics, and hydration tasks share one manager-owned state source.

**Files Changed**:

* `apps/server/src/server.ts` - imported and instantiated the command-center manager and passed it to dependency objects.
* `apps/server/src/ws/handlers.ts` - added the manager to the WebSocket handler context type.

* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T009 complete after evidence was recorded.

**Verification**:

* Command/check: `npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "OrchestrationCommandCenterManager|commandCenter" apps/server/src/server.ts apps/server/src/ws/handlers.ts apps/server/src/lib/orchestrationDiagnostics.ts`
  * Result: PASS - manager construction and dependency passing are present.
  * Evidence: found server construction plus WebSocket and diagnostics dependency fields.
* UI product-surface check: N/A - server dependency wiring only.
* UI craft check: N/A - server dependency wiring only.

**Started**: 2026-06-26 02:13 **Completed**: 2026-06-26 02:14 **Duration**: 1 minute

**Notes**:

* Added `apps/server/src/routes/commandCenter.ts` with read-only snapshot endpoints under `/command-center/*`.
* Snapshot routes cover capabilities, plans, tasks, attention, executors, heroes, executions, permissions, file intents, workpads, evidence, verification, review gates, handoffs, diagnostics, channels, usage, and notification readiness.
* Snapshot routes parse typed scope queries and run expiry cleanup before returning manager snapshots.

**Files Changed**:

* `apps/server/src/routes/commandCenter.ts` - added command-center snapshot route module and shared snapshot helper.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.

  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "command-center/(capabilities|plans|tasks|attention|executors|heroes|executions|permissions|file-intents|workpads|evidence|verification|handoffs|diagnostics|channels|usage|notification-readiness)|addSnapshotRoute" apps/server/src/routes/commandCenter.ts`
  * Result: PASS - snapshot routes and shared route helper are present.
  * Evidence: found all required route families plus `addSnapshotRoute`.
* UI product-surface check: N/A - server REST route module only.
* UI craft check: N/A - server REST route module only.

**BQC Fixes**:

* State freshness on re-entry: snapshot routes call manager expiry cleanup before list responses (`apps/server/src/routes/commandCenter.ts`).
* Trust boundary enforcement: snapshot routes parse scope queries through command-center validation adapters before reading manager state (`apps/server/src/routes/commandCenter.ts`).

***

### Task T011 - Add scaffold mutation routes

**Started**: 2026-06-26 02:14 **Completed**: 2026-06-26 02:16 **Duration**: 2 minutes

**Notes**:

* Added scaffold mutation endpoints for plan campaigns, plan tasks, attention, permissions, permission decisions, unavailable execution results, file intents, verification attempts, review gates, handoffs, channel commands, and notification readiness.
* Routes validate request bodies through command-center parser adapters before touching manager state.
* Execution result route accepts only unavailable scaffold results so no executor path can be triggered from this session.

**Files Changed**:

* `apps/server/src/routes/commandCenter.ts` - added mutation route bindings and compact manager-result response handling.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T011 complete after evidence was recorded.

**Verification**:

* Command/check: `npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "r\\.post\\(\\\"/command-center/(plans|tasks|attention|permissions|executions/unavailable|file-intents|verification|review-gates|handoffs|channels|notification-readiness)|sendMutationResult" apps/server/src/routes/commandCenter.ts`
  * Result: PASS - scaffold mutation routes and result handling are present.
  * Evidence: found all required mutation route families plus `sendMutationResult`.
* UI product-surface check: N/A - server REST route implementation only.
* UI craft check: N/A - server REST route implementation only.

**BQC Fixes**:

* Trust boundary enforcement: every mutation route uses protocol-backed command-center validation before manager writes (`apps/server/src/routes/commandCenter.ts`).
* Failure path completeness: unavailable execution routes reject non-unavailable states with compact validation errors instead of falling through to execution (`apps/server/src/routes/commandCenter.ts`).
* Duplicate action prevention: routes delegate idempotency and expected-revision enforcement to the manager mutation layer (`apps/server/src/routes/commandCenter.ts`).

***

### Task T012 - Add shared route mutation wrapper and event emission

**Started**: 2026-06-26 02:16 **Completed**: 2026-06-26 02:18 **Duration**: 2 minutes

**Notes**:

* Added a shared `runMutation` route wrapper with route-local in-flight locks and compact conflict responses.
* Routed every command-center mutation through the wrapper.
* Emitted the matching compact `command_center_*_update` event only after the manager accepted a mutation.

**Files Changed**:

* `apps/server/src/routes/commandCenter.ts` - added shared route mutation wrapper, in-flight lock set, mutation keys, and broadcaster emissions.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T012 complete after evidence was recorded.

**Verification**:

* Command/check: `npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0 after annotating the helper status parameter.
* Command/check: `rg -n "runMutation|inFlightMutations|broadcaster.emit|mutationKey|RestConflictErrorResponse" apps/server/src/routes/commandCenter.ts`
  * Result: PASS - shared in-flight wrapper and compact event emission are present.
  * Evidence: found `runMutation`, route-local lock set, conflict response type, mutation keys, and `broadcaster.emit`.
* UI product-surface check: N/A - server route mutation wrapper only.
* UI craft check: N/A - server route mutation wrapper only.

**BQC Fixes**:

* Duplicate action prevention: added route-level in-flight locks in addition to manager-level idempotency checks (`apps/server/src/routes/commandCenter.ts`).
* Failure path completeness: manager failures return without emitting WebSocket events, so rejected mutations do not produce false-positive updates (`apps/server/src/routes/commandCenter.ts`).

***

### Task T013 - Mount command-center routes at root and /api

**Started**: 2026-06-26 02:18 **Completed**: 2026-06-26 02:18 **Duration**: 1 minute

**Notes**:

* Imported the command-center router in server startup.
* Mounted it through `mountLocalApiRoutes`, so the same route module is registered at both root and `/api`.

**Files Changed**:

* `apps/server/src/server.ts` - mounted `commandCenterRouter({ broadcaster, commandCenter })` in local API route registration.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T013 complete after evidence was recorded.

**Verification**:

  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "commandCenterRouter|commandCenter" apps/server/src/server.ts`
  * Result: PASS - router import, manager construction, and mount are present.
  * Evidence: found `commandCenterRouter` import and root/API registration path.
* UI product-surface check: N/A - server route mounting only.
* UI craft check: N/A - server route mounting only.

***

### Task T014 - Add command-center WebSocket hydration frames

**Started**: 2026-06-26 02:18 **Completed**: 2026-06-26 02:19 **Duration**: 1 minute

**Notes**:

* Appended command-center hydration frames after the existing guarded-action hydration event.
* Added cleanup before hydration so expired scaffold state is not sent as fresh state.
* Used manager-owned `hydrationEvents()` for deterministic command-center frame ordering.

**Files Changed**:

* `apps/server/src/ws/handlers.ts` - appended command-center cleanup and hydration event sending.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T014 complete after evidence was recorded.

  * Evidence: found cleanup and `hydrationEvents()` loop in `sendOrchestrationHydration`.
* UI product-surface check: N/A - server WebSocket hydration only.
* UI craft check: N/A - server WebSocket hydration only.

**BQC Fixes**:

* State freshness on re-entry: each new WebSocket connection triggers command-center expiry cleanup before hydration frames are sent (`apps/server/src/ws/handlers.ts`).
* Error information boundaries: hydration uses compact event builders rather than raw manager records (`apps/server/src/ws/handlers.ts`).

***

  * Evidence: found command-center dependency, snapshot fields, cleanup, compact count usage, and capability count helper.
* UI product-surface check: N/A - diagnostics endpoint implementation only.
* UI craft check: N/A - diagnostics endpoint implementation only.

**BQC Fixes**:

* Error information boundaries: diagnostics use bounded count maps and capability totals instead of raw command-center records (`apps/server/src/lib/orchestrationDiagnostics.ts`).
* State freshness on re-entry: diagnostics run command-center expiry cleanup before reporting counts (`apps/server/src/lib/orchestrationDiagnostics.ts`).

**Started**: 2026-06-26 02:23 **Completed**: 2026-06-26 02:25 **Duration**: 2 minutes

**Notes**:

* Added command-center route tests through the real `createFactionOsServer` factory.
* Covered root and `/api` snapshot parity, capability unavailable envelopes, scaffold mutation responses, WebSocket event emission, idempotent duplicates, stale revision conflicts, validation redaction, and unavailable-only execution routes.

**Files Changed**:

* `apps/server/tests/commandCenterRoutes.test.ts` - added focused route tests for snapshots, mutations, event emission, validation, `/api` parity, stale revisions, and unavailable execution boundaries.
* `.spec_system/specs/phase19-session02-server-backbone/implementation-notes.md` - recorded task evidence.
* `.spec_system/specs/phase19-session02-server-backbone/tasks.md` - marked T018 complete after evidence was recorded.

**Verification**:

* Command/check: `npx vitest run apps/server/tests/commandCenterRoutes.test.ts`
  * Result: PASS - 1 test file passed.
  * Evidence: 3 tests passed.
* Command/check: `npm --workspace apps/server run typecheck`
  * Result: PASS - server TypeScript compilation succeeded.
  * Evidence: `tsc --noEmit` completed with exit code 0.
* Command/check: `rg -n "capabilities|/api/command-center|emits compact events|stale|validation errors|unavailable-only|readFrames\\(socket, 26\\)" apps/server/tests/commandCenterRoutes.test.ts`
  * Result: PASS - route test coverage targets are present.
  * Evidence: found assertions for capability snapshots, `/api` prefix, WebSocket mutation events, stale conflicts, validation errors, unavailable execution, and command-center hydration count.
* UI product-surface check: N/A - server route tests only.
* UI craft check: N/A - server route tests only.

**BQC Fixes**:

* Trust boundary enforcement: route tests verify blocked raw fields return compact validation errors without raw prompt or token echoes (`apps/server/tests/commandCenterRoutes.test.ts`).
* Contract alignment: route tests validate root and `/api` route behavior plus compact WebSocket event emission (`apps/server/tests/commandCenterRoutes.test.ts`).
* Failure path completeness: route tests verify stale revision conflicts and unavailable-only execution enforcement (`apps/server/tests/commandCenterRoutes.test.ts`).
