### Task T002 - Focused Baseline Tests

**Started**: 2026-05-30 04:46 **Completed**: 2026-05-30 04:46 **Duration**: 1 minute

**Notes**:

* Ran focused protocol, Worker, and web War Room tests before making new event-contract edits.
* Command passed: `npx vitest run packages/protocol/tests/warroom.test.ts apps/warroom/tests/warroom.test.ts apps/web/tests/warRoomClient.test.ts apps/web/tests/warRoomFederation.test.ts apps/web/tests/warRoomStore.test.ts apps/web/tests/WarRoomPanel.test.tsx`.
* Result: 6 test files passed, 85 tests passed.
* Cloudflare credentials were not required; Worker paths used local test harnesses and mocked browser/socket behavior.

**Files Changed**:

* `.spec_system/specs/phase06-session03-shared-collaboration-event-contracts/implementation-notes.md` - Recorded baseline test evidence.

**BQC Fixes**:

* N/A - baseline verification only.

***

### Task T003 - Protocol Event Contracts

**Started**: 2026-05-30 04:47 **Completed**: 2026-05-30 04:49 **Duration**: 2 minutes

**Notes**:

* Added protocol-owned recent-event and catch-up envelope parsers.
* Recent events now validate timestamp, sender participant id, unknown fields, persistable safe-frame payloads, blocked keys, and sensitive string values through shared error envelopes.
* Catch-up envelopes now require `warroom_pending_catchup`, a bounded event array, and schema-valid safe recent events.

**Files Changed**:

* `packages/protocol/src/warroom.ts` - Added `parseWarRoomRecentEvent`, `parseWarRoomCatchupFrame`, and `filterSafeWarRoomRecentEvents`.

**BQC Fixes**:

* Trust boundary enforcement: recent-event and catch-up inputs are schema-validated in protocol before Worker or web consumption.
* Error information boundaries: parser failures map to compact protocol errors without echoing raw payloads.

***

### Task T004 - Protocol Safety Tests

**Started**: 2026-05-30 04:48 **Completed**: 2026-05-30 04:49 **Duration**: 1 minute

**Notes**:

* Added tests for recent events, catch-up caps, blocked values, invalid senders, ping non-persistence in catch-up, and compact family summaries.
* Command passed: `npx vitest run packages/protocol/tests/warroom.test.ts`.
* Result: 1 test file passed, 15 tests passed.

**Files Changed**:

* `packages/protocol/tests/warroom.test.ts` - Extended War Room protocol coverage for new event and summary contracts.

**BQC Fixes**:

* Contract alignment: protocol tests now cover the new parser and summary contracts before Worker and web usage.

***

### Task T005 - Shared Family Labels And Summaries

**Started**: 2026-05-30 04:48 **Completed**: 2026-05-30 04:49 **Duration**: 1 minute

**Notes**:

* Added protocol-owned compact recent-event family summary types and helpers.
* Summary output is deterministic by safe family label and reports counts/timestamps only, not target ids, mission ids, hero ids, or raw payloads.

**Files Changed**:

* `packages/protocol/src/warroom.ts` - Added `warRoomFederationFamilyLabel` and `summarizeWarRoomRecentEvents`.
* `packages/protocol/tests/warroom.test.ts` - Verified deterministic labels and no raw payload details in summary copy.

**BQC Fixes**:

* Error information boundaries: summaries expose only counts, family labels, and timestamps.

***

### Task T006 - Protocol Documentation

**Started**: 2026-05-30 04:50 **Completed**: 2026-05-30 04:50 **Duration**: 1 minute

**Notes**:

* Documented protocol ownership for safe socket frames, recent-event parsing, catch-up parsing, safe filtering, family labels, and compact summaries.
* Reiterated blocked collaboration categories and summary limits.

**Files Changed**:

* `packages/protocol/README_protocol.md` - Added Session 03 contract ownership and helper guidance.

**BQC Fixes**:

* N/A - documentation update only.

***

### Task T007 - Protocol Decisions And Deferrals

**Started**: 2026-05-30 04:51 **Completed**: 2026-05-30 04:51 **Duration**: 1 minute

**Notes**:

* Protocol remains the source of truth for safe socket frames, safe recent events, catch-up envelopes, sender-facing family labels, and catch-up summaries.
* Catch-up parsing fails closed for malformed envelopes, while Worker legacy storage filtering can drop unsafe entries before delivery.
* Summary helpers intentionally expose family counts and timestamps only. Raw target ids, labels, commands, prompts, file paths, diagnostics, logs, exports, replay buffers, settings, and media drafts stay out of summary copy.
* Residual deferrals remain unchanged: hosted identity, hosted storage, analytics, public replay hosting, remote execution, mobile certification, production-hosted validation, and trusted erasure are not Session 03 behavior.

**Files Changed**:

* `.spec_system/specs/phase06-session03-shared-collaboration-event-contracts/implementation-notes.md` - Recorded protocol decisions and residual deferrals.

**BQC Fixes**:

* N/A - implementation note update only.

***

## Design Decisions

### Decision 1: Protocol-Owned Catch-Up Parsing

**Context**: Worker and web code both handle recent events and catch-up frames. Duplicated validation would let malformed or legacy unsafe frames diverge by consumer.

**Options Considered**:

1. Keep Worker and web validators local - simpler short term, but higher drift risk.
2. Add shared protocol parsers and safe-filter helpers - slightly broader protocol API, but one contract for both consumers.

**Chosen**: Add shared protocol parsers and safe-filter helpers.

**Rationale**: Session 03 explicitly requires protocol-owned recent-event and catch-up contracts before Worker and web behavior.

### Decision 2: Summary Copy Uses Family Counts Only

**Context**: Catch-up and remote context should be visible without exposing raw payload details.

**Options Considered**:

1. Include safe ids or labels in summaries - more specific, but risks leaking local workflow vocabulary.
2. Include only counts, timestamps, and family labels - less specific, but matches the privacy boundary.

**Chosen**: Include only counts, timestamps, and family labels.

**Rationale**: This keeps summaries useful while preserving the blocked payload and source-of-truth separation rules.

***

### Task T008 - Worker Socket Ingest And Persistence

**Started**: 2026-05-30 04:50 **Completed**: 2026-05-30 04:51 **Duration**: 1 minute

**Notes**:

* Verified socket setup remains authority-bound by participant id and Worker-issued authority token.
* Socket ingest continues to parse client frames through shared protocol validation and returns compact `warroom_error` frames for malformed, unsafe, blocked, or unknown frames.
* `ping` remains non-persistable through the protocol `persist: false` path.

**Files Changed**:

* `apps/warroom/src/index.ts` - Wired recent-event filtering to the protocol-owned safe filter.

**BQC Fixes**:

* Trust boundary enforcement: Worker storage and catch-up now use shared protocol validation for persisted recent events.
* Error information boundaries: socket errors keep compact protocol error codes and details.

***

### Task T009 - Worker Sender Exclusion And Catch-Up

**Started**: 2026-05-30 04:50 **Completed**: 2026-05-30 04:51 **Duration**: 1 minute

**Notes**:

* Verified remote broadcasts still skip the sending socket participant.
* Recent-event storage remains capped to `WAR_ROOM_MAX_RECENT_EVENTS`.
* Catch-up uses shared `filterSafeWarRoomRecentEvents`, preserving deterministic stored order while dropping malformed or legacy unsafe entries before delivery.
* Socket send failures still trigger participant disconnect cleanup.

**Files Changed**:

* `apps/warroom/src/index.ts` - Replaced local recent-event filtering with the shared protocol helper.

**BQC Fixes**:

* Resource cleanup: failed socket sends still disconnect and clean participant state.
* Contract alignment: Worker catch-up filtering now matches the protocol parser used by web consumers.

***

### Task T010 - Worker Socket And Catch-Up Tests

**Started**: 2026-05-30 04:51 **Completed**: 2026-05-30 04:51 **Duration**: 1 minute

**Notes**:

* Verified Worker tests cover malformed frames, blocked fields, sender exclusion, capped catch-up, ping non-persistence, and unsafe legacy recent-event filtering.
* Command passed: `npx vitest run apps/warroom/tests/warroom.test.ts`.
* Result: 1 test file passed, 28 tests passed.

**Files Changed**:

* `apps/warroom/src/index.ts` - Shared protocol filtering integration under existing Worker coverage.

**BQC Fixes**:

* Contract alignment: Worker behavior remains covered against shared protocol-safe events.

***

### Task T011 - Web Client Socket Frame Parsing

**Started**: 2026-05-30 04:51 **Completed**: 2026-05-30 04:52 **Duration**: 1 minute

**Notes**:

* Tightened browser socket frame type guards for inbound `remote_event` and `warroom_pending_catchup` frames.
* Inbound remote events now require a protocol-valid sender and persistable safe frame.
* Inbound catch-up envelopes now use the protocol catch-up parser before dispatching to store state.
* Outbound send failures continue to return compact client failures without echoing frame bodies.

**Files Changed**:

* `apps/web/src/lib/warRoomClient.ts` - Added protocol catch-up validation for inbound socket frames.

**BQC Fixes**:

* Trust boundary enforcement: Worker socket frames are validated before browser state receives them.
* Failure path completeness: unreadable frames use the existing visible bad-response failure path.

***

### Task T015 - Web Client Socket Safety Tests

**Started**: 2026-05-30 04:52 **Completed**: 2026-05-30 04:52 **Duration**: 1 minute

**Notes**:

***

### Task T012 - Web Federation Builders And Mergers

**Started**: 2026-05-30 04:52 **Completed**: 2026-05-30 04:53 **Duration**: 1 minute

**Notes**:

* Tightened outbound federation builders to choose safe hero, mission, and optional mission hero ids before frame construction.
* Inbound merge behavior remains dedicated to remote context and continues to parse remote frames through protocol validation.
* Remote summaries remain counts and family labels only, with no raw payload wording.

**Files Changed**:

* `apps/web/src/lib/warRoomFederation.ts` - Guarded outbound hero, mission, and focus frames with safe identifiers before construction.

**BQC Fixes**:

* Trust boundary enforcement: unsafe IDs are dropped before outbound frame construction.
* Contract alignment: outbound helpers still pass protocol frame validation before send.

***

### Task T016 - Web Federation Helper Tests

**Started**: 2026-05-30 04:53 **Completed**: 2026-05-30 04:53 **Duration**: 1 minute

**Notes**:

* Added coverage that invalid mission hero ids are omitted from outbound frames while valid mission state/focus frames remain sendable.
* Command passed: `npx vitest run apps/web/tests/warRoomFederation.test.ts`.
* Result: 1 test file passed, 6 tests passed.

**Files Changed**:

* `apps/web/tests/warRoomFederation.test.ts` - Extended outbound safe-ID coverage.

**BQC Fixes**:

* Contract alignment: federation helper tests cover redacted outbound IDs and local source-of-truth separation.

### Task T013 - War Room Store Remote Context Handling

**Started**: 2026-05-30 04:53 **Completed**: 2026-05-30 04:54 **Duration**: 1 minute

**Notes**:

* Verified duplicate federation sends remain guarded by `inFlight.federationSend`.
* Catch-up summaries now delegate to the protocol-owned compact recent-event summary helper.
* Reconnect, Worker URL changes, disconnect, leave, reset, rejected joins, and participant pruning continue to clear or prune remote context without mutating local source-of-truth state.
* Added store coverage for scoped federation send failure rollback.

**Files Changed**:

* `apps/web/src/lib/warRoomPresence.ts` - Reused the protocol-owned recent-event summary helper.
* `apps/web/tests/warRoomStore.test.ts` - Added scoped send failure coverage.

**BQC Fixes**:

* Duplicate action prevention: existing in-flight guard remains covered.
* Failure path completeness: failed federation sends now have explicit test coverage for error state and in-flight cleanup.
* Contract alignment: catch-up summaries use the shared protocol contract.

***

### Task T014 - War Room Panel Collaboration Summary

**Started**: 2026-05-30 04:54 **Completed**: 2026-05-30 04:55 **Duration**: 1 minute

**Notes**:

* Added an explicit accessible status label to the redacted federation summary.
* Visible and accessible summary copy uses `remoteSummary` label/description only and does not render raw payload wording.

**Files Changed**:

* `apps/web/src/components/WarRoomPanel.tsx` - Added `role="status"` and a safe `aria-label` for the federation summary.

**BQC Fixes**:

* Accessibility and platform compliance: redacted federation summary now has an accessible status label.
