Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available * [x] Directory structure ready *** ### Task T001 - Verify Worker contract coverage **Started**: 2026-05-30 00:39 **Completed**: 2026-05-30 00:39 **Duration**: 1 minute **Notes**: * Confirmed existing Worker tests cover join pending broadcasts, approve, reject, stale decisions, non-leader decisions, socket close cleanup, participant snapshots, and bounded catch-up behavior. * Confirmed Worker runtime already exposes approve, reject, participant-change, socket-close, and catch-up contracts through protocol-owned envelopes. **Files Changed**: * `.spec_system/specs/phase05-session04-join-approval-presence-and-reconnect-ux/implementation-notes.md` - Started implementation log. **BQC Fixes**: * N/A - verification task only. *** ### Task T002 - Verify Session 03 web baseline **Started**: 2026-05-30 00:39 **Completed**: 2026-05-30 00:40 **Duration**: 1 minute **Notes**: * Confirmed `useWarRoomStore` already hydrates bounded identity hints, creates and joins rooms, revalidates snapshots before socket connect, and cleans up sockets on disconnect/reset/hydration. * Confirmed `WarRoomPanel` currently renders lifecycle controls, room hints, local-only fallback, and duplicate guards for create/join/connect/disconnect/reset. * Confirmed fake socket utilities already support open, message, error, close, and server close paths for Session 04 extension. **Files Changed**: * `.spec_system/specs/phase05-session04-join-approval-presence-and-reconnect-ux/implementation-notes.md` - Logged baseline verification. **BQC Fixes**: * N/A - verification task only. *** ### Task T003 - Verify README boundary notes **Started**: 2026-05-30 00:40 **Completed**: 2026-05-30 00:41 **Duration**: 1 minute **Notes**: * Confirmed `apps/web/README_web.md` still states Session 03 lifecycle scope and defers approval, detailed roster, reconnect, catch-up display, leave semantics, and federation. * Confirmed `apps/warroom/README_warroom.md` documents the Worker routes, deterministic error envelopes, participant roles, bounded catch-up, sender-excluded broadcast, and redaction boundary. * Identified README updates needed after implementation to move Session 04 behavior from deferred to shipped while keeping Session 05 federation out of scope. **Files Changed**: * `.spec_system/specs/phase05-session04-join-approval-presence-and-reconnect-ux/implementation-notes.md` - Logged README baseline verification. **BQC Fixes**: * N/A - verification task only. *** ### Task T004 - Extend typed Worker client helpers **Started**: 2026-05-30 00:41 **Completed**: 2026-05-30 00:43 **Duration**: 2 minutes **Notes**: * Added `approveWarRoomJoin` and `rejectWarRoomJoin` helpers that normalize room codes, validate decision payloads with the protocol parser, and post to typed Worker routes. * Added response validation for `WarRoomJoinDecisionResponse` and explicit safe copy for stale decisions and non-leader decisions. **Files Changed**: * `apps/web/src/lib/warRoomClient.ts` - Added decision helpers, schema validation, and safe error mapping. **BQC Fixes**: * Trust boundary enforcement: join decision input is validated before crossing the Worker boundary. * Failure path completeness: stale and non-leader Worker errors map to bounded user-facing failures. *** ### Task T005 - Create presence and catch-up helpers **Started**: 2026-05-30 00:43 **Completed**: 2026-05-30 00:46 **Duration**: 3 minutes **Notes**: * Added pure helpers for sorted roster rows, pending approval rows, reconnect copy, pending-join lookup, and bounded catch-up summaries. * Catch-up summaries aggregate only safe event family counts and timestamps, avoiding raw event payload values. **Files Changed**: * `apps/web/src/lib/warRoomPresence.ts` - New helper module for roster, approval, reconnect, and catch-up UI derivation. **BQC Fixes**: * Contract alignment: role labels and participant sorting reuse protocol-owned contracts. * Error information boundaries: catch-up summaries expose only counts, timestamps, and safe event families. *** ### Task T006 - Extend War Room store state **Started**: 2026-05-30 00:46 **Completed**: 2026-05-30 00:49 **Duration**: 3 minutes **Notes**: * Added per-requester decision in-flight state, decision failure state, reconnect counters, catch-up summary state, and honest leave/reset notice state. * Reset, hydration, create, join, connect, and disconnect paths now clear or preserve the new participation state at lifecycle boundaries. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Extended store shape and lifecycle resets for Session 04 participation state. **BQC Fixes**: * Resource cleanup: hydration and reset close existing sockets and clear participation state. * State freshness on re-entry: create, join, connect, and reset paths clear stale decision/catch-up/leave state. *** ### Task T007 - Add presence helper tests **Started**: 2026-05-30 00:49 **Completed**: 2026-05-30 00:52 **Duration**: 3 minutes **Notes**: * Added tests for roster ordering, local participant labels, pending approval row state, observer display, reconnect copy, and catch-up redaction. * Verified helper expectations avoid raw focus targets, presence labels, and cursor coordinates in catch-up summaries. **Files Changed**: * `apps/web/tests/warRoomPresence.test.ts` - New focused tests for Session 04 helper derivation. **BQC Fixes**: * Accessibility and platform compliance: tests assert text labels for role/status/local state rather than color-only treatment. * Error information boundaries: tests assert catch-up summaries do not include raw event payload values. *** ### Task T008 - Extend fake browser socket utilities **Started**: 2026-05-30 00:52 **Completed**: 2026-05-30 00:54 **Duration**: 2 minutes **Notes**: * Added semantic socket frame emitters for participant changes, pending joins, join approval, join rejection, and catch-up frames. * Added listener-count inspection to support cleanup assertions in reconnect and disconnect tests. **Files Changed**: * `apps/web/tests/warRoomTestUtils.ts` - Extended fake WebSocket helpers for Session 04 socket lifecycle coverage. **BQC Fixes**: * Resource cleanup: fake sockets can now assert listener removal after close/replacement. * Contract alignment: helper frames use protocol-owned participant and catch-up types. *** ### Task T009 - Add Worker fixture assertions **Started**: 2026-05-30 00:54 **Completed**: 2026-05-30 00:56 **Duration**: 2 minutes **Notes**: * Added focused Worker fixture evidence for pending snapshot shape, non-leader decision envelope, approval snapshot update, and stale reject envelope. * Kept Worker runtime unchanged because existing routes already satisfy the Session 04 contracts. **Files Changed**: * `apps/warroom/tests/warroom.test.ts` - Added focused approval snapshot and deterministic error envelope assertions. **BQC Fixes**: * Contract alignment: Worker evidence now locks the response shapes consumed by the web client and store. * Error information boundaries: tests assert deterministic bounded error envelopes for decision failures. *** ### Task T010 - Implement approve and reject store actions **Started**: 2026-05-30 00:56 **Completed**: 2026-05-30 01:00 **Duration**: 4 minutes **Notes**: * Added `approveJoin` and `rejectJoin` store actions with leader-only gating, stale pending detection, per-requester in-flight flags, decision failure state, and duplicate-trigger prevention. * Successful and failed Worker decisions now revalidate the room snapshot when possible, with a local snapshot fallback for successful decisions. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added decision actions and snapshot reconciliation helpers. **BQC Fixes**: * Duplicate action prevention: repeated approve/reject calls for the same requester are ignored while in flight. * Trust boundary enforcement: non-leaders are rejected in the store before a Worker decision request is issued. * State freshness on re-entry: decisions refresh the Worker snapshot before updating visible roster state. *** ### Task T011 - Handle participation socket frames **Started**: 2026-05-30 01:00 **Completed**: 2026-05-30 01:03 **Duration**: 3 minutes **Notes**: * Updated socket frame handling for pending joins, participant changes, approvals, rejections, remote events, catch-up placeholders, and socket error frames. * Approval and rejection frames now reconcile snapshots, clear in-flight decision state, and close the local socket when the local participant is rejected. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Expanded socket frame participation handling and decision-state cleanup. **BQC Fixes**: * Contract alignment: each current Worker server frame type is handled explicitly. * State freshness on re-entry: participant changes remove stale in-flight decisions for requests that are no longer pending. * Error information boundaries: socket error frames continue to map to bounded failure copy. *** ### Task T012 - Implement reconnect and retry policy **Started**: 2026-05-30 01:03 **Completed**: 2026-05-30 01:08 **Duration**: 5 minutes **Notes**: * Added bounded manual retry with three attempts, increasing backoff, explicit retry in-flight state, and an unavailable failure when the retry cap is reached. * Retry closes any existing socket before reconnecting, reuses snapshot and socket validation, and cancels pending retry timers on hydrate, reset, or disconnect. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added retry action, retry selector, backoff timer cleanup, and retry exhaustion failure copy. **BQC Fixes**: * Resource cleanup: reconnect timers are canceled on reset, hydrate, and disconnect. * External dependency resilience: Worker socket retry uses bounded attempts and backoff on top of the client timeout. * Failure path completeness: retry exhaustion surfaces a visible bounded failure state. *** ### Task T013 - Implement bounded catch-up summary state **Started**: 2026-05-30 01:08 **Completed**: 2026-05-30 01:10 **Duration**: 2 minutes **Notes**: * Store catch-up handling now converts Worker catch-up frames into redacted summary state and moves lifecycle copy to `caught-up`. * Raw Worker catch-up event bodies are not stored in UI state. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added catch-up frame summary handling. **BQC Fixes**: * Error information boundaries: catch-up state stores only safe summary metadata, not raw payloads. * Contract alignment: catch-up handling consumes protocol-owned `warroom_pending_catchup` frames. *** ### Task T014 - Implement leave and disconnect semantics **Started**: 2026-05-30 01:10 **Completed**: 2026-05-30 01:13 **Duration**: 3 minutes **Notes**: * Added `leaveRoom` as a distinct local room-context exit that closes sockets, clears local room state, and does not claim trusted erasure. * Disconnect now preserves room context and records copy that it only closed this browser socket. * Reset copy was tightened to avoid claiming Worker storage, browser hints, logs, archives, exports, or replay buffers were erased. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added leave action and clearer disconnect/reset semantics. **BQC Fixes**: * Duplicate action prevention: leave ignores repeated triggers while in flight. * Resource cleanup: leave cancels retry timers and closes the active socket before clearing local state. * Error information boundaries: leave/reset copy avoids trusted-erasure claims. *** ### Task T015 - Add participant roster component **Started**: 2026-05-30 01:13 **Completed**: 2026-05-30 01:15 **Duration**: 2 minutes **Notes**: * Added a compact roster component that renders participant name, role, online/offline or pending status, and local participant marker. * Each row exposes an accessibility label with the same role/status/local state shown visually. **Files Changed**: * `apps/web/src/components/WarRoomRoster.tsx` - New accessible participant roster component. **BQC Fixes**: * Accessibility and platform compliance: roster state is text-labeled and exposed through row labels instead of color-only indicators. *** ### Task T016 - Add leader approval queue component **Started**: 2026-05-30 01:15 **Completed**: 2026-05-30 01:18 **Duration**: 3 minutes **Notes**: * Added a compact approval queue with approve/reject controls, non-leader unavailable copy, disabled in-flight behavior, and row-level failure copy. * Buttons use stable accessible names for pending requester decisions. **Files Changed**: * `apps/web/src/components/WarRoomApprovalQueue.tsx` - New leader approval/rejection queue component. **BQC Fixes**: * Duplicate action prevention: rows disable both decision controls while a requester decision is in flight. * Accessibility and platform compliance: decision buttons have requester-specific accessible labels. * Failure path completeness: stale and non-leader failures render visible row feedback. *** ### Task T017 - Wire participation UI into War Room panel **Started**: 2026-05-30 01:18 **Completed**: 2026-05-30 01:22 **Duration**: 4 minutes **Notes**: * Wired approval queue, participant roster, retry, disconnect, leave, reset, catch-up summary, and honest leave/disconnect notices into the panel. * Kept cockpit event federation and battlefield overlays explicitly deferred to Session 05. **Files Changed**: * `apps/web/src/components/WarRoomPanel.tsx` - Integrated Session 04 participation controls and state. **BQC Fixes**: * Failure path completeness: reconnect, catch-up, leave, and decision failures all have visible panel states. * Duplicate action prevention: panel disables retry and leave while those actions are in flight. * Accessibility and platform compliance: approval controls and roster are composed from accessible subcomponents. *** ### Task T018 - Update War Room lifecycle and error copy **Started**: 2026-05-30 01:22 **Completed**: 2026-05-30 01:24 **Duration**: 2 minutes **Notes**: * Updated reconnecting, caught-up, rejected, and left lifecycle copy for shipped Session 04 behavior. * Added safe copy for stale join decisions and non-leader decision attempts. **Files Changed**: * `apps/web/src/lib/warRoomUi.ts` - Updated lifecycle and decision error copy. **BQC Fixes**: * Failure path completeness: stale and non-leader decision codes now have explicit UI copy. * Error information boundaries: caught-up copy describes metadata without raw payload claims. *** ### Task T019 - Update web README Phase 05 notes **Started**: 2026-05-30 01:24 **Completed**: 2026-05-30 01:27 **Duration**: 3 minutes **Notes**: * Updated web README language from Session 03 lifecycle-only behavior to shipped Session 04 participation behavior. * Documented approval, presence, bounded retry, catch-up redaction, leave/reset limitations, and Session 05 federation deferrals. **Files Changed**: * `apps/web/README_web.md` - Updated web War Room boundary notes. **BQC Fixes**: * N/A - documentation task only. *** ### Task T020 - Update Worker README behavior notes **Started**: 2026-05-30 01:27 **Completed**: 2026-05-30 01:29 **Duration**: 2 minutes **Notes**: * Updated Worker README language for the Session 04 web integration boundary. * Clarified reject route behavior, deterministic decision envelopes, participant online/offline presence, bounded catch-up, and disconnect-only leave semantics. **Files Changed**: * `apps/warroom/README_warroom.md` - Updated Worker behavior and integration notes. **BQC Fixes**: * N/A - documentation task only. *** ### Task T021 - Add client decision tests **Started**: 2026-05-30 01:29 **Completed**: 2026-05-30 01:33 **Duration**: 4 minutes **Notes**: * Added approve/reject success coverage with typed request body assertions. * Added decision failure coverage for invalid input, non-leader, stale decision, rate-limit, Worker unavailable, and malformed responses. **Files Changed**: * `apps/web/tests/warRoomClient.test.ts` - Extended War Room client tests for Session 04 decision helpers. **BQC Fixes**: * Trust boundary enforcement: tests assert invalid decision payloads are blocked before request. * Failure path completeness: tests assert safe mapping for decision-specific Worker failures. *** ### Task T022 - Add store participation tests **Started**: 2026-05-30 01:33 **Completed**: 2026-05-30 01:39 **Duration**: 6 minutes **Notes**: * Added store coverage for duplicate approval guards, snapshot revalidation, non-leader decisions, stale decisions, participant-change frames, catch-up summaries, leave cleanup, socket listener cleanup, and bounded retry exhaustion. **Files Changed**: * `apps/web/tests/warRoomStore.test.ts` - Extended War Room store tests for Session 04 participation behavior. **BQC Fixes**: * Duplicate action prevention: tests assert one Worker decision request during duplicate approval. * Resource cleanup: tests assert socket listeners are removed after leave closes the connection. * External dependency resilience: tests assert bounded retry exhaustion produces visible failure state. * Error information boundaries: tests assert catch-up summaries do not expose raw focus targets. *** ### Task T023 - Add panel participation tests **Started**: 2026-05-30 01:39 **Completed**: 2026-05-30 01:45 **Duration**: 6 minutes **Notes**: * Added component coverage for leader approval controls, roster accessibility labels, non-leader disabled copy, rejected state, leave copy, and catch-up summary redaction. * Existing panel tests continue to cover local-only, invalid Worker URL, create, pending join, connect/disconnect, and Worker unavailable feedback. **Files Changed**: * `apps/web/tests/WarRoomPanel.test.tsx` - Extended panel tests for Session 04 participation UX. **BQC Fixes**: * Accessibility and platform compliance: tests assert roster rows and decision controls have meaningful accessible names. * Error information boundaries: tests assert catch-up panel output does not include raw Worker focus targets. * Failure path completeness: tests assert rejected and non-leader states are visible. *** ### Task T024 - Run focused validation **Started**: 2026-05-30 01:45 **Completed**: 2026-05-30 01:57 **Duration**: 12 minutes **Notes**: * Formatted touched Session 04 source, test, and documentation files with Biome. * Ran focused Worker and web tests for helper, client, store, panel, and Worker contracts. * Ran targeted Biome lint for touched web and Worker source/test files. * Ran package typechecks for `apps/web` and `apps/warroom`. * Ran ASCII and CR/LF validation across Session 04 implementation files. **Files Changed**: * `.spec_system/specs/phase05-session04-join-approval-presence-and-reconnect-ux/tasks.md` -
