Created session implementation log. ### Task T002 - Verify protocol exports and web dependency **Started**: 2026-05-30 00:07 **Completed**: 2026-05-30 00:08 **Duration**: 1 minute **Notes**: * Confirmed `apps/web/package.json` already depends on `@factionos/protocol`. * Confirmed `packages/protocol/src/index.ts` exports `warroom.ts`. * Confirmed Session 02 Worker REST and socket contracts exist in `packages/protocol/src/warroom.ts`. **Files Changed**: * `.spec_system/specs/phase05-session03-web-room-lifecycle-and-state-store/tasks.md` - Marked verification tasks complete. ### Task T003 - Create War Room web test utilities **Started**: 2026-05-30 00:08 **Completed**: 2026-05-30 00:09 **Duration**: 1 minute **Notes**: * Added JSON/text `Response` helpers for focused client and component tests. * Added a controllable mock WebSocket with open, message, error, server-close, and close-call tracking. * Added browser-state reset helper for localStorage and WebSocket instances. **Files Changed**: * `apps/web/tests/warRoomTestUtils.ts` - Created shared War Room testing helpers. * `.spec_system/specs/phase05-session03-web-room-lifecycle-and-state-store/tasks.md` - Marked T003 complete. ### Task T004 - Create typed Worker client foundation **Started**: 2026-05-30 00:09 **Completed**: 2026-05-30 00:16 **Duration**: 7 minutes **Notes**: * Added typed client success/failure result shapes, injected fetch/WebSocket/timer dependencies, and Worker URL normalization. * Rejected missing, non-http, credentialed, and oversized Worker URLs before network calls. **Files Changed**: * `apps/web/src/lib/warRoomClient.ts` - Created Worker client boundary. ### Task T005 - Create bounded identity persistence helpers **Started**: 2026-05-30 00:09 **Completed**: 2026-05-30 00:16 **Duration**: 7 minutes **Notes**: * Added bounded persistence for Worker URL, participant id, and participant display name only. * Added malformed JSON recovery, invalid stored URL fallback, storage exception handling, and reset helper. **Files Changed**: * `apps/web/src/lib/warRoomIdentity.ts` - Created War Room hint persistence helpers. ### Task T007 - Create lifecycle copy and tone helpers **Started**: 2026-05-30 00:09 **Completed**: 2026-05-30 00:16 **Duration**: 7 minutes **Notes**: * Added helper-owned copy for local-only, unavailable, pending, approved, connected, disconnected, and deferred lifecycle states. * Added bounded error copy and room-code input normalization helpers for component and tests. **Files Changed**: * `apps/web/src/lib/warRoomUi.ts` - Created War Room UI helper module. ### Task T010 - Implement Worker REST requests **Started**: 2026-05-30 00:09 **Completed**: 2026-05-30 00:16 **Duration**: 7 minutes **Notes**: * Added health, snapshot, create-room, and join-room requests with timeout-backed fetch. * Validated response shapes before returning success and mapped Worker error envelopes to safe UI failures. **Files Changed**: * `apps/web/src/lib/warRoomClient.ts` - Added REST request implementations. **BQC Fixes**: * External dependency resilience: all fetch calls use bounded timeout and explicit offline, timeout, HTTP, rate-limit, and bad-response failures (`apps/web/src/lib/warRoomClient.ts`). * Error information boundaries: UI failures use protocol-owned or generic copy without echoing raw request bodies, URLs, stack traces, paths, prompts, or tokens (`apps/web/src/lib/warRoomClient.ts`). ### Task T011 - Implement socket URL and cleanup helpers **Started**: 2026-05-30 00:09 **Completed**: 2026-05-30 00:16 **Duration**: 7 minutes **Notes**: * Added socket URL construction from Worker URL, room code, and validated participant id. * Added open-timeout handling, listener cleanup, close helper, and bounded socket frame parsing. **Files Changed**: * `apps/web/src/lib/warRoomClient.ts` - Added scoped socket lifecycle helpers. **BQC Fixes**: * Resource cleanup: socket listeners and open timers are removed on open, close, error, timeout, and explicit disconnect (`apps/web/src/lib/warRoomClient.ts`). * Failure path completeness: failed upgrades, unreadable frames, timeouts, unavailable sockets, and close-before-open paths produce visible failures (`apps/web/src/lib/warRoomClient.ts`). ### Task T006 - Create War Room Zustand store shape **Started**: 2026-05-30 00:16 **Completed**: 2026-05-30 00:18 **Duration**: 9 minutes **Notes**: * Added War Room store state for Worker URL hints, participant hints, room code, role, lifecycle state, last safe snapshot, socket connection, in-flight flags, and bounded error state. * Added selector helpers for create, join, connect, and disconnect availability. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Created War Room Zustand store. ### Task T012 - Implement hint hydration and reset **Started**: 2026-05-30 00:16 **Completed**: 2026-05-30 00:18 **Duration**: 9 minutes **Notes**: * Store hydrates bounded hints from `warRoomIdentity` and recovers malformed storage through the helper. * Hint saving persists only Worker URL, participant id, and participant name. * Local room reset closes any socket and clears room state without storing events or sensitive local data. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added hydration, hint saving, and reset behavior. **BQC Fixes**: * State freshness on re-entry: hydration and reset close the prior socket and rebuild room state from bounded hints (`apps/web/src/store/useWarRoomStore.ts`). * Error information boundaries: invalid hint errors use safe validation copy without echoing raw URLs (`apps/web/src/store/useWarRoomStore.ts`). ### Task T013 - Implement create-room action **Started**: 2026-05-30 00:16 **Completed**: 2026-05-30 00:18 **Duration**: 9 minutes **Notes**: * Added guarded create-room action that no-ops while a create request is already in flight. * Captures returned leader participant and room code, preserves a safe snapshot, and maps Worker-unavailable failures. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added create-room lifecycle action. **BQC Fixes**: * Duplicate action prevention: create-room returns early while `inFlight.createRoom` is true (`apps/web/src/store/useWarRoomStore.ts`). * Failure path completeness: unavailable, invalid input, HTTP, rate-limit, and bad-response failures update visible store error state (`apps/web/src/store/useWarRoomStore.ts`). ### Task T014 - Implement join-room action **Started**: 2026-05-30 00:16 **Completed**: 2026-05-30 00:18 **Duration**: 9 minutes **Notes**: * Added guarded join-room action with local room-code normalization and validation. * Maps pending, full, not-found, rate-limited, unavailable, and invalid-code outcomes into lifecycle and error state. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added join-room lifecycle action. **BQC Fixes**: * Duplicate action prevention: join-room returns early while `inFlight.joinRoom` is true (`apps/web/src/store/useWarRoomStore.ts`). * Trust boundary enforcement: room code and participant hints are normalized before Worker calls (`apps/web/src/store/useWarRoomStore.ts`). ### Task T015 - Implement connect and disconnect actions **Started**: 2026-05-30 00:16 **Completed**: 2026-05-30 00:18 **Duration**: 9 minutes **Notes**: * Connect revalidates the latest snapshot before opening a socket and refuses pending or missing participants. * Disconnect and reset close the scoped socket connection and remove socket references from the store. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added connect, disconnect, socket-frame, and cleanup behavior. **BQC Fixes**: * Resource cleanup: disconnect, reset, hydration, rejected join frames, and failed transitions close the active socket (`apps/web/src/store/useWarRoomStore.ts`). * State freshness on re-entry: connect re-fetches the room snapshot before opening the socket (`apps/web/src/store/useWarRoomStore.ts`). * Failure path completeness: failed socket opening, pending approval, missing participant, and Worker-unavailable paths update bounded UI error state (`apps/web/src/store/useWarRoomStore.ts`). ### Task T009 - Update shell metadata copy **Started**: 2026-05-30 00:18 **Completed**: 2026-05-30 00:20 **Duration**: 10 minutes **Notes**: * Changed War Room shell metadata from deferred stub copy to optional Worker lifecycle copy. * Surface status now reflects an available optional panel rather than a deferred surface. **Files Changed**: * `apps/web/src/lib/cockpitShell.ts` - Updated War Room boundary metadata. ### Task T016 - Replace disabled War Room panel **Started**: 2026-05-30 00:18 **Completed**: 2026-05-30 00:20 **Duration**: 10 minutes **Notes**: * Replaced the stub with Worker URL, participant name, room code, create, join, connect, disconnect, reset, and status controls. * Added labels, helper text, status region, form submit behavior, disabled states, and unmount socket cleanup. **Files Changed**: * `apps/web/src/components/WarRoomPanel.tsx` - Implemented accessible room lifecycle controls. **BQC Fixes**: * Accessibility and platform compliance: inputs have visible labels, helper text, and native form submit support; status uses `role=status` or `role=alert` as appropriate (`apps/web/src/components/WarRoomPanel.tsx`). * Resource cleanup: panel unmount disconnects any active socket through the store (`apps/web/src/components/WarRoomPanel.tsx`). ### Task T017 - Render lifecycle and error states **Started**: 2026-05-30 00:18 **Completed**: 2026-05-30 00:20 **Duration**: 10 minutes **Notes**: * Added visible local-only, loading, invalid input, unavailable, pending, connected, disconnected, and rate-limited status paths. * Error/status copy is helper-owned and avoids raw request, URL, token, path, prompt, command, export, replay, media, scan, and diagnostic payload output. **Files Changed**: * `apps/web/src/components/WarRoomPanel.tsx` - Added status, summary, and bounded error rendering. **BQC Fixes**: * Failure path completeness: all user-triggered Worker paths have visible status or error feedback (`apps/web/src/components/WarRoomPanel.tsx`). * Error information boundaries: status messages render safe client/store copy rather than raw Worker bodies or sensitive local state (`apps/web/src/components/WarRoomPanel.tsx`). ### Task T018 - Update web README notes **Started**: 2026-05-30 00:18 **Completed**: 2026-05-30 00:20 **Duration**: 10 minutes **Notes**: * Documented shipped Session 03 lifecycle controls, local-only fallback, bounded persistence, and Session 04-05 deferrals. **Files Changed**: * `apps/web/README_web.md` - Updated Phase 05 War Room boundary documentation. ### Task T008 - Add identity persistence tests **Started**: 2026-05-30 00:20 **Completed**: 2026-05-30 00:23 **Duration**: 13 minutes **Notes**: * Added coverage for defaults, valid hints, malformed JSON recovery, invalid URL rejection, oversized names, and reset. **Files Changed**: * `apps/web/tests/warRoomIdentity.test.ts` - Added focused identity persistence tests. ### Task T019 - Add Worker client tests **Started**: 2026-05-30 00:20 **Completed**: 2026-05-30 00:23 **Duration**: 13 minutes **Notes**: * Added REST client tests for success, offline, timeout, malformed response, rate limit, and room errors. * Added socket URL and scoped close tests. **Files Changed**: * `apps/web/tests/warRoomClient.test.ts` -
