Session Start **Environment verified**: * [x] Prerequisites confirmed with `.spec_system/scripts/check-prereqs.sh --json --env` * [x] Tools available: Node v24.14.0, npm 10.5.1, jq 1.7, git 2.43.0 * [x] Directory structure ready * [x] Cloudflare credentials not required for focused local and mocked tests *** ### Task T001 - Review baseline and package context **Started**: 2026-05-30 03:58 **Completed**: 2026-05-30 03:58 **Duration**: 4 minutes **Notes**: * Reviewed Session 01 baseline, Phase 06 routing matrix, Session 02 PRD stub, root project overview, architecture docs, Cloudflare Worker ADR, and package READMEs for protocol, Worker, and web. * Confirmed cross-package scope is `packages/protocol`, `apps/warroom`, and `apps/web`; stable docs are also in scope. * Current authority gap is that Worker lifecycle and socket flows are validated and redacted, but participant authority still primarily trusts caller-supplied participant ids and browser hints. * Current worktree already contains unrelated spec archive moves and doc/package edits; this session will work with the existing dirty state without reverting unrelated files. **Files Changed**: * `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/implementation-notes.md` - Created implementation evidence log and recorded cross-package scope. **BQC Fixes**: * N/A - setup and documentation evidence only. *** ### Task T002 - Verify focused baseline commands **Started**: 2026-05-30 03:58 **Completed**: 2026-05-30 03:59 **Duration**: 1 minute **Notes**: * Ran focused pre-change War Room tests: `npx vitest run packages/protocol/tests/warroom.test.ts apps/warroom/tests/warroom.test.ts apps/web/tests/warRoomClient.test.ts apps/web/tests/warRoomStore.test.ts apps/web/tests/WarRoomPanel.test.tsx`. * Result: 5 test files passed, 76 tests passed. * Ran package typechecks: `npm --workspace packages/protocol run typecheck`, `npm --workspace @factionos/warroom run typecheck`, and `npm --workspace @factionos/web run typecheck`. * Result: all three typechecks passed. * No Cloudflare credentials, deployed Worker access, hosted auth, analytics, or hosted storage were required. **Files Changed**: * `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/implementation-notes.md` - Recorded baseline command evidence and no-credential assumptions. **BQC Fixes**: * N/A - baseline verification only. *** ### Task T003 - Extend protocol authority contracts **Started**: 2026-05-30 03:59 **Completed**: 2026-05-30 04:02 **Duration**: 3 minutes **Notes**: * Added shared authority envelopes with room code, participant id, role, room revision, issue time, expiration time, and Worker-issued opaque token. * Added room revision and authority metadata to create, init, join, decision, and snapshot contracts. * Added idempotency key support for create, join, and join decision request validators. * Added deterministic error codes for missing, invalid, expired, mismatched, stale revision, and replayed authority inputs. **Files Changed**: * `packages/protocol/src/warroom.ts` - Added authority constants, types, error codes, response/request fields, and validators. **BQC Fixes**: * Trust boundary enforcement: added schema validation for authority envelopes, authority tokens, room revisions, and idempotency keys. * Error information boundaries: new envelopes expose stable codes and bounded field names only, not tokens or raw request bodies. * Contract alignment: protocol contracts now carry the revision and authority metadata Worker and web consumers need. *** ### Task T004 - Add protocol authority parser tests **Started**: 2026-05-30 04:00 **Completed**: 2026-05-30 04:02 **Duration**: 2 minutes **Notes**: * Added tests for authority envelope parsing, socket authority token parsing, unknown authority fields, malformed role/code/token values, and revision/idempotency request parsing. * Verified protocol coverage with `npx vitest run packages/protocol/tests/warroom.test.ts`. * Verified package types with `npm --workspace packages/protocol run typecheck`. **Files Changed**: * `packages/protocol/tests/warroom.test.ts` - Added authority parser, type, enum, and malformed-input coverage. **BQC Fixes**: * Contract alignment: tests cover success and malformed shapes before Worker and web consumers use the fields. *** ### Task T005 - Create Worker authority helper **Started**: 2026-05-30 04:02 **Completed**: 2026-05-30 04:09 **Duration**: 7 minutes **Notes**: * Added a room-local authority helper that issues opaque `wrp_` tokens, stores SHA-256 token hashes, verifies room/participant/role/expiration, prunes expired records, and detects duplicate or replayed idempotency keys. * Authority records stay scoped to the Durable Object room boundary and do not require checked-in secrets, signing keys, hosted accounts, or Cloudflare credentials. **Files Changed**: * `apps/warroom/src/authority.ts` - Added authority issue, verify, expiration, rotation, idempotency, duplicate, and replay helpers. **BQC Fixes**: * Trust boundary enforcement: verification checks token possession against stored hashes and room/participant/role expectations. * Error information boundaries: helper returns compact envelopes and does not persist raw authority tokens. * Duplicate action prevention: idempotency helpers distinguish first, duplicate, and replayed mutation keys. *** ### Task T006 - Add Worker authority helper tests **Started**: 2026-05-30 04:03 **Completed**: 2026-05-30 04:09 **Duration**: 6 minutes **Notes**: * Added helper tests for issue, raw-token exclusion from stored records, valid verification, missing authority, expired authority, mismatched authority, role mismatch, rotation invalidation, pruning, duplicate decisions, and replayed idempotency keys. * Verified with `npx vitest run apps/warroom/tests/authority.test.ts`. **Files Changed**: * `apps/warroom/tests/authority.test.ts` - Added focused authority helper coverage. **BQC Fixes**: * Contract alignment: tests prove helper outcomes map to the protocol authority error vocabulary. *** ### Task T007 - Update Worker create, join, and snapshot behavior **Started**: 2026-05-30 04:04 **Completed**: 2026-05-30 04:09 **Duration**: 5 minutes **Notes**: * Create/init now issues leader authority and returns `roomRevision`. * Join now issues pending participant authority; duplicate joins require existing authority and rotate the participant authority response. * Snapshot now requires participant authority through bounded query parameters and returns room revision metadata. **Files Changed**: * `apps/warroom/src/index.ts` - Added room revision state, persisted authority records, create/join/snapshot authority enforcement, and rehydration defaults. * `apps/warroom/tests/warroom.test.ts` - Updated Worker lifecycle tests to pass authority-bearing requests and assert revision-bearing responses. **BQC Fixes**: * Trust boundary enforcement: snapshot and duplicate join paths no longer rely on participant id hints alone. * State freshness on re-entry: duplicate joins rotate authority so clients can refresh stale room authority. *** ### Task T008 - Harden Worker approve and reject behavior **Started**: 2026-05-30 04:05 **Completed**: 2026-05-30 04:09 **Duration**: 4 minutes **Notes**: * Approve/reject now require leader authority, expected room revision, and idempotency metadata. * Duplicate decisions with the same idempotency key return the stored response with `duplicate: true`; reused keys with different decision fingerprints return `replayed_authority`. * Approved participants keep their existing token possession while Worker-side role metadata is promoted; rejected participants have authority removed. **Files Changed**: * `apps/warroom/src/index.ts` - Added leader authority verification, stale revision errors, idempotency replay checks, participant authority promotion/removal, and revision increments. * `apps/warroom/tests/warroom.test.ts` - Updated approve/reject tests for authority and duplicate-idempotent decisions. **BQC Fixes**: * Duplicate action prevention: decision idempotency prevents repeated approve/reject retries from mutating state twice. * Concurrency safety: expected room revision rejects stale decision attempts before mutation. * Failure path completeness: non-leader, stale revision, stale join, missing authority, and replay paths return explicit envelopes. *** ### Task T009 - Harden Worker socket and reconnect behavior **Started**: 2026-05-30 04:06 **Completed**: 2026-05-30 04:09 **Duration**: 3 minutes **Notes**: * Socket setup now requires participant authority after participant and pending-state checks. * Online/offline socket state increments room revision and replacement sockets still close the old socket before accepting the new one. * Rehydrated Durable Object tests copy issued authority into the test room so reconnect/catch-up paths exercise stored authority. **Files Changed**: * `apps/warroom/src/index.ts` - Added socket authority token validation and revision updates for connect/disconnect state. * `apps/warroom/tests/warroom.test.ts` - Updated socket and rehydration tests for authority-bearing socket URLs. **BQC Fixes**: * Resource cleanup: socket replacement and close handling continue to remove stale sockets and mark participants offline. * State freshness on re-entry: reconnect requires current stored authority and revalidates persisted catch-up events. *** ### Task T010 - Extend Worker lifecycle tests **Started**: 2026-05-30 04:09 **Completed**: 2026-05-30 04:11 **Duration**: 2 minutes **Notes**: * Added explicit lifecycle coverage for stale room revisions, malformed authority envelopes, mismatched duplicate joins, replayed idempotency keys, missing socket authority, malformed socket authority, and expired socket authority. * Verified with `npx vitest run apps/warroom/tests/authority.test.ts apps/warroom/tests/warroom.test.ts`. * Verified Worker package types with `npm --workspace @factionos/warroom run typecheck`. **Files Changed**: * `apps/warroom/tests/warroom.test.ts` - Added focused authority failure and replay lifecycle tests. **BQC Fixes**: * Failure path completeness: lifecycle tests cover bounded errors for stale, malformed, mismatched, replayed, missing, and expired authority. * Error information boundaries: assertions check stable codes without raw token or request-body echo. *** ### Task T011 - Update web War Room client authority handling **Started**: 2026-05-30 04:11 **Completed**: 2026-05-30 04:20 **Duration**: 9 minutes **Notes**: * Added authority-bearing create, join, snapshot, approve/reject, and socket handling to the web client. * Added response parsing for authority and revision fields plus bounded authority error mapping. * Verified with web client tests and `npm --workspace @factionos/web run typecheck`. **Files Changed**: * `apps/web/src/lib/warRoomClient.ts` - Added authority request fields, socket authority query construction, response guards, and safe authority failure mapping. **BQC Fixes**: * Trust boundary enforcement: client validates authority-bearing responses before store consumption. * External dependency resilience: existing timeout handling now applies to authority-aware requests. * Error information boundaries: authority errors map to bounded copy and do not echo response tokens. *** ### Task T012 - Update browser identity hint handling **Started**: 2026-05-30 04:12 **Completed**: 2026-05-30 04:20 **Duration**: 8 minutes **Notes**: * Kept browser identity persistence limited to Worker URL, participant id, and display name hints. * Added a helper so the store clears room authority when Worker URL or participant id changes. **Files Changed**: * `apps/web/src/lib/warRoomIdentity.ts` - Added `shouldResetWarRoomAuthority` without persisting authority tokens. **BQC Fixes**: * State freshness on re-entry: authority is reset when persisted hints point at a different Worker URL or participant. *** ### Task T013 - Update War Room store authority state **Started**: 2026-05-30 04:12 **Completed**: 2026-05-30 04:20 **Duration**: 8 minutes **Notes**: * Added in-memory authority and authority status state. * Create/join now store Worker-issued authority, connect/snapshot/socket paths require authority, and approve/reject send authority plus expected revision and idempotency keys. * Hydration, Worker URL changes, leave, reset, rejected joins, expired/mismatched authority failures, and stale authority failures clear or mark authority state. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - Added authority state, request wiring, stale cleanup, failure status mapping, and revision-aware snapshot fallback. **BQC Fixes**: * Duplicate action prevention: decision requests carry idempotency keys while existing in-flight guards remain. * State freshness on re-entry: hydration, Worker URL changes, connect, join decisions, leave, and reset clear or revalidate authority. * Failure path completeness: authority failures update visible store error/status state instead of silently failing. *** ### Task T014 - Update War Room UI copy helpers **Started**: 2026-05-30 04:16 **Completed**: 2026-05-30 04:20 **Duration**: 4 minutes **Notes**: * Added bounded labels for authority status and copy for missing, invalid, expired, mismatched, stale revision, and replayed authority errors. **Files Changed**: * `apps/web/src/lib/warRoomUi.ts` - Added authority labels and authority error copy. **BQC Fixes**: * Error information boundaries: UI copy does not include raw tokens, URLs, request bodies, or account wording. *** ### Task T015 - Update War Room panel authority display **Started**: 2026-05-30 04:17 **Completed**: 2026-05-30 04:20 **Duration**: 3 minutes **Notes**: * Added visible authority state to the active room metrics. * The panel reports authority as `None`, `Issued`, `Expired`, `Mismatch`, or `Stale`; it does not render raw authority tokens. **Files Changed**: * `apps/web/src/components/WarRoomPanel.tsx` - Added authority status display. **BQC Fixes**: * Accessibility and platform compliance: authority state is text, not color-only. * Error information boundaries: no token or account-proof wording is shown. *** ### Task T016 - Document protocol authority ownership and proof limits **Started**: 2026-05-30 04:20 **Completed**: 2026-05-30 04:24 **Duration**: 4 minutes **Notes**: * Documented `packages/protocol/src/warroom.ts` as the source of truth for non-hosted War Room authority envelopes, token bounds, room revisions, idempotency keys, expiration, and stable authority error vocabulary. * Documented proof limits: authority proves possession of one Worker-issued room-local token, not hosted identity, organization membership, public collaboration safety, or trusted erasure. **Files Changed**: * `packages/protocol/README_protocol.md` - Added Phase 06 Session 02 authority ownership and proof-limit guidance. **BQC Fixes**: * Contract alignment: docs now route Worker and web consumers to shared protocol types instead of package-local authority shapes. * Error information boundaries: docs state that authority errors must not echo tokens, request bodies, URLs, paths, diagnostics, or logs. *** ### Task T017 - Document Worker authority behavior **Started**: 2026-05-30 04:20 **Completed**: 2026-05-30 04:24 **Duration**: 4 minutes **Notes**: * Documented Worker-issued room-local authority, hash-only Durable Object storage, current-authority requirements, expected revisions, idempotency keys, duplicate decision behavior, and replay failures. * Expanded the stable Worker error-code list to include authority and revision failures. * Kept non-hosted identity wording explicit for account proof, production auditability, public collaboration safety, and trusted deletion. **Files Changed**: * `apps/warroom/README_warroom.md` - Added Room Authority behavior and compact error guidance. **BQC Fixes**: * Trust boundary enforcement: docs now describe the Worker enforcement points for snapshot, duplicate join, decision, and socket setup. * Error information boundaries: docs explicitly avoid raw-token persistence and output. *** ### Task T018 - Document browser authority state **Started**: 2026-05-30 04:24 **Completed**: 2026-05-30 04:25 **Duration**: 1 minute **Notes**: * Documented browser authority as memory-only room state, separate from persisted Worker URL, participant id, and display name hints. * Recorded authority reset behavior for hydration, Worker URL changes, participant changes, leave/reset, rejected joins, missing/invalid/expired/mismatched authority, stale revision, and replay failures. * Preserved local-only fallback and non-erasure wording for Worker storage, browser hints, logs, archives, exports, replay buffers, backups, memory, settings, and future hosted data. **Files Changed**: * `apps/web/README_web.md` - Added Phase 06 War Room authority state guidance. **BQC Fixes**: * State freshness on re-entry: docs now list authority cleanup and stale-state conditions. * Error information boundaries: docs state the UI must not display raw authority tokens or account-proof wording. *** ### Task T019 - Update stable API, privacy, and operations docs **Started**: 2026-05-30 04:25 **Completed**: 2026-05-30 04:26 **Duration**: 1 minute **Notes**: * Updated the stable War Room Worker API reference with authority-aware create, snapshot, join, approve, reject, and socket shapes. * Updated privacy inventory and transfer boundary docs for raw browser-held authority, hash-only Durable Object storage, idempotency metadata, and Phase 07/08 deferrals. * Updated the War Room operations runbook with authority-required snapshot/socket checks and triage guidance for missing, invalid, expired, mismatched, stale, replayed, and non-leader failures. **Files Changed**: * `docs/api/README_api.md` - Documented authority-aware Worker API shapes, error codes, sensitive-output exclusions, and deferrals. * `docs/privacy-and-security.md` - Added authority metadata inventory, transfer limits, privacy controls, and release risks. * `docs/runbooks/war-room-operations.md` - Added authority-sensitive operational checks and failure triage. **BQC Fixes**: * Trust boundary enforcement: stable docs now identify which routes require current authority and expected revision. * Error information boundaries: docs now explicitly exclude authority tokens from logs, diagnostics, URLs in incident notes, exports, replay state, and user-facing output. *** ### Task T020 - Extend web client authority tests **Started**: 2026-05-30 04:17 **Completed**: 2026-05-30 04:20 **Duration**: 3 minutes **Notes**: * Updated web client fixtures for authority-bearing responses and socket URLs. * Added authority error mapping coverage that excludes raw token-like response fields. **Files Changed**: * `apps/web/tests/warRoomClient.test.ts` - Added authority fixtures, request body checks, socket URL checks, and safe error mapping coverage. **BQC Fixes**: * Contract alignment: tests cover request and response shape changes. * Error information boundaries: tests assert sensitive authority response fields are not surfaced. *** ### Task T021 - Extend web store authority tests **Started**: 2026-05-30 04:17 **Completed**: 2026-05-30 04:20 **Duration**: 3 minutes **Notes**: * Updated store fixtures for authority-bearing create, join, connect, approve, reconnect, and Worker URL change flows. * Added assertion that Worker URL changes clear authority and authority status. **Files Changed**: * `apps/web/tests/warRoomStore.test.ts` - Added authority fixtures and stale authority cleanup checks. **BQC Fixes**: * State freshness on re-entry: tests cover authority cleanup on Worker URL changes and hydration-controlled flows. *** ### Task T022 - Extend War Room panel authority tests **Started**: 2026-05-30 04:18 **Completed**: 2026-05-30 04:20 **Duration**: 2 minutes **Notes**: * Updated panel fixtures for authority-bearing create, join, approve, and connect flows. * Added visible authority-state assertions for local-only and issued authority states. **Files Changed**: * `apps/web/tests/WarRoomPanel.test.tsx` - Added authority fixtures and visible authority state checks. **BQC Fixes**: * Accessibility and platform compliance: tests verify authority state appears as visible text. *** ### Task T023 - Run focused tests and package typechecks **Started**: 2026-05-30 04:27 **Completed**: 2026-05-30 04:28 **Duration**: 1 minute **Notes**: * Ran `npx biome format --write --files-ignore-unknown=true` against the touched TypeScript and documentation paths before final validation; Biome formatted 14 files and fixed 6 files. * Ran focused War Room tests: `npx vitest run packages/protocol/tests/warroom.test.ts apps/warroom/tests/authority.test.ts apps/warroom/tests/warroom.test.ts apps/web/tests/warRoomClient.test.ts apps/web/tests/warRoomStore.test.ts apps/web/tests/WarRoomPanel.test.tsx`. * Result: 6 test files passed, 84 tests passed. * Ran package typechecks: `npm --workspace packages/protocol run typecheck`, `npm --workspace @factionos/warroom run typecheck`, and `npm --workspace @factionos/web run typecheck`. * Result: all three typechecks passed. **Files Changed**: * `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/implementation-notes.md` - Recorded focused validation evidence. **BQC Fixes**: * Contract alignment: final focused tests and package typechecks validate the protocol, Worker, and web authority contract together. *** ### Task T024 - Validate ASCII encoding and LF line endings **Started**: 2026-05-30 04:28 **Completed**: 2026-05-30 04:29 **Duration**: 1 minute **Notes**: * Ran an explicit touched-file encoding check for non-ASCII bytes and CRLF line endings across 22 session files. * Result: ASCII and LF validation passed for all 22 files. **Files Changed**: * `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/tasks.md` - Marked final task and completion checklist done. * `.spec_system/specs/phase06-session02-room-authority-and-participant-identity-contracts/implementation-notes.md` - Recorded encoding and line-ending validation evidence. **BQC Fixes**: * N/A - encoding and closeout validation only. *** ## Session Closeout * Tasks completed: 24 / 24. * Focused tests: 6 War Room-related test files passed, 84 tests passed. * Typechecks: protocol, Worker, and web package typechecks passed. * Encoding: 22 touched files passed ASCII and LF checks. * Blockers: 0. * Ready for the validate workflow step. * Repo-root `npm test` initially surfaced `apps/warroom/tests/worker.test.ts` expectations that still reflected the old hint-only snapshot and decision flow. The test was aligned with the current authority token and post-join revision contract, then the full repo test suite was rerun successfully. --- # Agent Instructions This documentation is published with GitBook.
