**Notes**:

* Reviewed Session 02 inventory rows for Worker participants, recent events, authority hashes, idempotency records, room revisions, and browser hint adjacency.
* Reviewed Session 03 summary for local/browser runtime behavior and its no-overclaim handoff to Worker handling.
* Reviewed Phase 08 routing and risk matrices for P08-R007 through P08-R009 and P08-RISK-001/P08-RISK-004.
* Reviewed current War Room authority code: authority verification is room-local, uses hashed tokens, supports leader role enforcement, and already handles idempotent join decisions.

### Task T025 - Validate checklist and handoff readiness

**Started**: 2026-05-31 02:33 **Completed**: 2026-05-31 02:33 **Duration**: 1 minute

**Notes**:

* Marked all 25 implementation tasks complete and closed the completion checklist.
* Confirmed the implementation handoff documents the Worker room-state erasure scope, hosted identity no-claim gate, command outcomes, residual limitations, and validate-workflow next step.
* Session is ready for the validate workflow.

**Files Changed**:

### Task T024 - Run wording and file hygiene validation

**Started**: 2026-05-31 02:32 **Completed**: 2026-05-31 02:32 **Duration**: 1 minute

**Notes**:

* Reviewed Worker erasure and hosted identity wording across docs, UI copy, protocol, Worker, and server release-gate surfaces.
* Confirmed expected no-overclaim wording remains explicit: Worker erasure is one Durable Object room-record deletion; browser state, local filesystem state, hosted identity, production-hosted validation, and full trusted unified erasure remain separate or unavailable.
* No residual implementation blocker found. Residual release risk remains intentionally documented: Session 04 does not provide hosted identity, hosted account deletion, public replay takedown, production-hosted validation, or full trusted unified erasure.

**Files Changed**:

* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T024 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded validation outcomes.

**Command Results**:

* `git diff --check` - PASS.
* `rg` broad no-overclaim review over touched docs/code - PASS, expected boundary language found.
* `rg` risky-phrase review for overclaiming availability phrases - PASS, no matches.
* `LC_ALL=C rg -n '[^[:ascii:]]' ...` over touched text files - PASS, no non-ASCII matches.
* `rg -n $'\r' ...` over touched text files - PASS, no CRLF matches.

***

### Task T013 - Write Worker helper tests

**Started**: 2026-05-31 02:31 **Completed**: 2026-05-31 02:36 **Duration**: 5 minutes

**Notes**:

* Added helper coverage for sanitized previews, stale authority counts, idempotency counts, receipts, verification, and partial failure.
* Verified helper output does not include raw authority tokens, raw authority hashes, room payloads, or local paths.

**Files Changed**:

* `apps/warroom/tests/roomErasure.test.ts` - added Worker erasure helper tests.

**BQC Fixes**:

* Error information boundaries: tests assert redacted helper output.

***

### Task T014 - Write Durable Object erasure route tests

**Started**: 2026-05-31 02:36 **Completed**: 2026-05-31 02:42 **Duration**: 6 minutes

**Notes**:

* Added Durable Object tests for preview, confirm, non-leader authority, stale revision, bad confirmation, replayed keys, duplicate receipts, socket closure, room absence, and partial storage failure.
* Extended fake storage with delete and failure injection.

**Files Changed**:

* `apps/warroom/tests/warroom.test.ts` - added Durable Object erasure route tests.

**BQC Fixes**:

* Resource cleanup: tests verify sockets close after confirmed deletion.
* Failure path completeness: tests verify partial storage failure leaves room state in place.

***

### Task T015 - Write routed Worker erasure tests

**Started**: 2026-05-31 02:42 **Completed**: 2026-05-31 02:45 **Duration**: 3 minutes

**Notes**:

* Added Worker router tests for erasure endpoint CORS, malformed request validation, missing authority, no raw token/hash output, and missing room behavior.

**Files Changed**:

* `apps/warroom/tests/worker.test.ts` - added routed erasure endpoint tests and fake storage delete support.

***

### Task T016 - Write protocol erasure and hosted identity contract tests

**Files Changed**:

* `apps/server/tests/hostedIdentityDiagnostics.test.ts` - added hosted identity release gate assertions.

***

### Task T021 - Write web erasure client, panel, and hosted identity tests

**Started**: 2026-05-31 02:51 **Completed**: 2026-05-31 02:56 **Duration**: 5 minutes

**Notes**:

* Added web client tests for erasure preview/confirm, timeout, malformed response, authority failure, confirmation failure, and redaction.

***

### Task T020 - Update War Room store and panel erasure state

**Started**: 2026-05-31 02:27 **Completed**: 2026-05-31 02:31 **Duration**: 4 minutes

**Notes**:

* Added store state and actions for Worker erasure preview, confirmation input, confirm result, in-flight guards, and reset-on-reentry cleanup.
* Added War Room panel controls for leader-only preview and typed confirmation before confirmed room-state erasure.
* Confirm success clears stale room state, authority, sockets, remote context, and room code while preserving explicit no-overclaim completion copy.

**Files Changed**:

* `apps/web/src/store/useWarRoomStore.ts` - added Worker erasure preview/confirm state, actions, guards, and cleanup.
* `apps/web/src/components/WarRoomPanel.tsx` - surfaced Worker erasure preview/confirm UI and no-overclaim messaging.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T020 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T020 implementation.

**BQC Fixes**:

* Duplicate action prevention: preview and confirm have independent in-flight guards and confirm requires the exact typed phrase.
* State freshness on re-entry: create, join, hydrate, reset, leave, and Worker URL changes clear stale erasure state.
* Accessibility: destructive confirmation input and buttons use accessible labels and busy/disabled states.

***

### Task T019 - Update War Room erasure and no-overclaim copy

**Started**: 2026-05-31 02:25 **Completed**: 2026-05-31 02:27 **Duration**: 2 minutes

**Notes**:

* Added Worker erasure copy that distinguishes Durable Object room-record deletion from browser state, local files, hosted identity, production-hosted validation, and full trusted unified erasure.
* Added user-facing failure copy for erasure confirmation mismatch, missing idempotency key, and partial failure.
* Existing leave/reset copy continues to say browser context cleanup is not Worker or trusted erasure.

**Files Changed**:

* `apps/web/src/lib/warRoomUi.ts` - added Worker erasure copy and explicit erasure error wording.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T019 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T019 implementation.

**BQC Fixes**:

* Error information boundaries: UI error copy names stable states only and never displays raw Worker response values.

***

### Task T017 - Add hosted identity diagnostics release gate

**Started**: 2026-05-31 02:24 **Completed**: 2026-05-31 02:25 **Duration**: 1 minute

**Notes**:

* Server hosted identity diagnostics now include a protocol release gate object.
* The gate reports no active hosted auth runtime, account UI, OAuth, SSO, organization membership, analytics consent runtime, production audit proof, or trusted erasure claim.

**Files Changed**:

* `apps/server/src/lib/hostedIdentity.ts` - added `releaseGate` to diagnostics snapshots.
* `apps/web/src/lib/hostedIdentity.ts` - exposed the same protocol release gate to browser helpers.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T017 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T017 implementation.

**BQC Fixes**:

* Error information boundaries: release gate fields are booleans and labels only; no env values, account ids, OAuth values, or authority values are introduced.

***

### Task T012 - Implement confirmed Worker room-state deletion

**Started**: 2026-05-31 02:22 **Completed**: 2026-05-31 02:24 **Duration**: 2 minutes

**Notes**:

* Confirmed Worker erasure deletes the Durable Object `room` record, verifies post-delete absence, clears in-memory room state, closes active sockets, and stores a redacted erasure receipt.
* Duplicate confirm requests with the same idempotency key and fingerprint return the stored redacted receipt with `duplicate: true`.
* Storage delete, verification, and receipt-write failures return partial-failure summaries without raw room data.

**Files Changed**:

* `apps/warroom/src/index.ts` - added deletion, verification, socket closure, receipt storage, and duplicate handling.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T012 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T012 implementation.

**BQC Fixes**:

* Resource cleanup: active sockets are closed after room state is removed and before the response returns.
* State freshness on re-entry: in-memory room state is cleared after verified storage deletion.
* Failure path completeness: storage delete, post-delete verification, and receipt persistence each map to partial failure.

***

### Task T011 - Enforce destructive erasure preconditions

**Started**: 2026-05-31 02:21 **Completed**: 2026-05-31 02:22 **Duration**: 1 minute

**Notes**:

* Confirmed Worker erasure requires room-local leader authority, current room revision, exact confirmation phrase, and an idempotency key.
* Non-leader authority maps to `only_leader_can_decide`; stale revision maps to `stale_room_revision`.
* Confirmation mismatch and missing idempotency key are rejected before any storage mutation.

**Files Changed**:

* `apps/warroom/src/index.ts` - enforced authority, revision, confirmation, and idempotency checks.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T011 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T011 implementation.

**BQC Fixes**:

* Duplicate action prevention: idempotency receipt checks run before destructive storage mutation.
* Concurrency safety: expected revision prevents stale room snapshots from deleting newer room state.

***

### Task T010 - Wire Worker erasure Durable Object routes

**Started**: 2026-05-31 02:18 **Completed**: 2026-05-31 02:21 **Duration**: 3 minutes

**Notes**:

* Added `/erasure/preview` and `/erasure/confirm` POST handling inside the Durable Object room boundary.
* Route handlers parse request bodies with protocol validators before using request values.
* Partial storage failures return the protocol erasure partial-failure response instead of silent success.

**Files Changed**:

* `apps/warroom/src/index.ts` - wired preview/confirm Durable Object routes and error mapping.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T010 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T010 implementation.

**BQC Fixes**:

* Trust boundary enforcement: request parsing and authority checks happen inside the Durable Object before room storage mutation.
* Failure path completeness: malformed, authority, stale revision, replayed idempotency, and partial storage failures all return explicit responses.

***

### Task T009 - Add web Worker erasure client helpers

**Started**: 2026-05-31 02:16 **Completed**: 2026-05-31 02:18 **Duration**: 2 minutes

**Notes**:

* Added typed browser client helpers for Worker erasure preview and confirm.
* The helpers reuse the existing request path for URL normalization, fetch timeout, offline mapping, HTTP error mapping, malformed response detection, rate limits, and authority failures.
* Confirm requests are locally parsed before fetch so missing authority, stale/missing revision, confirmation mismatch, and missing idempotency key fail without network mutation.

**Files Changed**:

* `apps/web/src/lib/warRoomClient.ts` - added Worker erasure preview/confirm helpers and response validators.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T009 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T009 implementation.

**BQC Fixes**:

* Duplicate action prevention: confirm requires an idempotency key before the client sends a destructive request.
* Failure path completeness: client helpers map timeout, offline, malformed response, authority, invalid input, rate limit, and HTTP failure states.

***

### Task T008 - Update Worker erasure inventory metadata

**Started**: 2026-05-31 02:15 **Completed**: 2026-05-31 02:16 **Duration**: 1 minute

**Notes**:

* Updated Worker erasure inventory metadata to show a room-state destructive runtime can exist for `apps/warroom`.
* Kept `trustedUnifiedErasureAvailable` false and raw authority/hash/room payload exposure false.

**Files Changed**:

* `apps/warroom/src/erasureInventory.ts` - exposed Worker room-state runtime availability while preserving no trusted unified erasure claim.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T008 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T008 implementation.

**BQC Fixes**:

* Contract alignment: inventory metadata reflects the Worker room-state runtime without changing hosted or full trusted erasure claims.

***

### Task T007 - Create Worker room erasure helper

**Started**: 2026-05-31 02:10 **Completed**: 2026-05-31 02:15 **Duration**: 5 minutes

**Notes**:

* Added a Worker room erasure helper that builds sanitized preview, completed, already-erased, partial-failure, verification, audit, receipt, and fingerprint objects.
* Helper outputs labels, counts, statuses, booleans, synthetic receipt ids, and docs-derived blocked payload labels only.
* Raw authority tokens, authority hashes, participant secrets, room payloads, paths, and idempotency response bodies are not copied into helper responses.

**Files Changed**:

* `apps/warroom/src/roomErasure.ts` - added redacted Worker room erasure helper.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T007 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T007 implementation.

**BQC Fixes**:

* Error information boundaries: receipt ids are synthetic and response bodies contain no raw room, authority, participant-secret, or path values.
* Contract alignment: helper uses protocol Worker boundary ids, audit kinds, verification methods, and no-overclaim copy.

***

### Task T006 - Add hosted identity release gate summary

**Started**: 2026-05-31 02:09 **Completed**: 2026-05-31 02:10 **Duration**: 1 minute

**Notes**:

* Added a hosted identity release-gate summary derived from the existing planned/unavailable guardrail summary.
* The summary explicitly reports no active hosted auth runtime, hosted identity claim, SSO claim, organization membership claim, account UI, analytics consent runtime, public collaboration safety claim, production audit proof, or trusted erasure claim.

**Files Changed**:

* `packages/protocol/src/hostedIdentity.ts` - added release gate status vocabulary and no-claim summary builder.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T006 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T006 implementation.

**BQC Fixes**:

* Trust boundary enforcement: hosted identity release posture is represented as an explicit protocol no-claim object instead of inferring from Worker authority or environment values.

***

### Task T005 - Add Worker erasure runtime vocabulary

**Started**: 2026-05-31 02:08 **Completed**: 2026-05-31 02:09 **Duration**: 1 minute

**Notes**:

* Added `worker` as an erasure runtime scope with the explicit Worker confirmation phrase.
* Added protocol-owned Worker boundary ids and runtime claim labels for room-state deletion, receipt, snapshot absence, no hosted identity, and no trusted unified erasure.
* Extended no-overclaim copy so Worker erasure stays limited to one Durable Object room record.

**Files Changed**:

* `packages/protocol/src/erasure.ts` - added Worker runtime scope, phrase, boundary ids, claim labels, type guards, and no-overclaim copy.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T005 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T005 implementation.

**BQC Fixes**:

* Contract alignment: Worker erasure now has distinct runtime vocabulary without changing the full trusted unified erasure claim to available.

***

### Task T004 - Add Worker erasure War Room protocol contracts

**Started**: 2026-05-31 02:07 **Completed**: 2026-05-31 02:08 **Duration**: 1 minute

**Notes**:

* Added Worker erasure preview and confirm request contracts with authority, expected revision, confirmation phrase, and idempotency validation.
* Added response statuses, counts, boundary summaries, audit entries, verification entries, and no-overclaim response fields.
* Added mapped error codes for invalid erasure confirmation, missing idempotency key, and partial failure.

**Files Changed**:

* `packages/protocol/src/warroom.ts` - added Worker erasure contracts and parser helpers.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T004 complete and updated progress.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - recorded T004 implementation.

**BQC Fixes**:

* Contract alignment: confirm parsing requires typed authority, positive expected revision, exact confirmation phrase, and idempotency key before any Worker can mutate room state.
* Error information boundaries: new protocol responses expose labels, counts, statuses, and synthetic ids only.

***

### Task T003 - Create implementation notes scaffold

**Started**: 2026-05-31 02:06 **Completed**: 2026-05-31 02:06 **Duration**: 1 minute

**Notes**:

* Created the implementation notes scaffold with environment verification, cross-cutting package context, and scope guards.
* Recorded that Worker room-state deletion is narrower than full trusted unified erasure.
* Recorded that hosted identity remains a no-claim release gate because no active hosted auth runtime is in scope.

**Files Changed**:

* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/implementation-notes.md` - added scaffold and scope guard.
* `.spec_system/specs/phase08-session04-war-room-and-hosted-identity-release-gate/tasks.md` - marked T003 complete and updated progress.

***

### Task T001 - Verify analyzer state and routing context
