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

**Started**: 2026-05-31 01:17 **Completed**: 2026-05-31 01:17 **Duration**: 1 minute

**Notes**:

* Ran `.spec_system/scripts/analyze-project.sh --json`.
* Active session resolved to `phase08-session03-local-erasure-runtime-and-controls`.
* Session 02 appears in `completed_sessions`.
* Phase 08 is `in_progress`; Session 03 is the first incomplete Phase 08 candidate.
* `spec.md` declares `Package: Cross-cutting`, matching the phase routing metadata.

**Files Changed**:

* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md` - added workflow scaffold and session-start context.

***

### Task T002 - Map Session 02 erasure inventory boundaries

**Started**: 2026-05-31 01:17 **Completed**: 2026-05-31 01:18 **Duration**: 1 minute

**Notes**:

* Reviewed `.spec_system/PRD/phase_08/unified_erasure_inventory.md`.
* Local runtime implementation maps to `local_factionos_home`, archives, memory, settings, lifecycle, project-root state, logs, backups, valid spool, malformed spool, exports, diagnostics, scan runtime memory, and LLM runtime memory.
* Browser implementation maps to settings, replay fragments and buffers, War Room hints, local auth hints, and in-memory runtime state.
* Worker Durable Object, hosted identity/storage/analytics, public replay, push, remote access, broad workspace files, and full trusted unified erasure remain unsupported, manual-review, future-scope, or later-session boundaries.

**Files Changed**:

* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md` - logged inventory mapping.

***

### Task T003 - Confirm destructive erasure scope

**Started**: 2026-05-31 01:18 **Completed**: 2026-05-31 01:18 **Duration**: 1 minute

**Notes**:

* Implementation notes scaffold exists and will be updated after every task.
* Destructive execution is limited to explicit local filesystem and browser-local erasure after confirmation.
* The session will not delete Worker Durable Object state, hosted account/storage/analytics state, public replay state, push subscriptions, remote-access state, broad workspace source files, or claim full trusted unified erasure.

**Files Changed**:

* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md` - added destructive-scope guardrail.

***

### Task T004 - Add protocol runtime erasure contracts

**Started**: 2026-05-31 01:18 **Completed**: 2026-05-31 01:21 **Duration**: 3 minutes

**Notes**:

* Added protocol-owned local/browser runtime boundary ids, unsupported runtime boundary ids, runtime action/status/verification vocabularies, confirmation phrases, route constants, request/result/audit/verification shapes, no-overclaim helpers, type guards, and count helpers.
* Kept inventory-derived summaries pure and deterministic with no side effects or raw payload/path fields.
* Added protocol tests for runtime vocabulary, confirmation phrases, idempotency-compatible result shape, partial-failure status vocabulary, unsupported boundaries, and no-overclaim wording.

**Files Changed**:

* `packages/protocol/src/erasure.ts` - runtime erasure contracts and helpers.
* `packages/protocol/tests/erasure.test.ts` - runtime contract coverage.

**BQC Fixes**:

* Contract alignment: added shared status and boundary ids before package-specific consumers use them (`packages/protocol/src/erasure.ts`).
* Error information boundaries: runtime summaries expose labels/counts/docs only and tests assert sensitive fixture strings are absent (`packages/protocol/tests/erasure.test.ts`).

**Verification**:

* `npx vitest run packages/protocol/tests/erasure.test.ts` - passed.

***

### Task T005 - Create safe local erasure path resolver

**Started**: 2026-05-31 01:21 **Completed**: 2026-05-31 01:25 **Duration**: 4 minutes

**Notes**:

* Added `resolveLocalErasurePaths` with FactionOS home, archives, memory, settings, lifecycle, project-root state, logs, backups, spool, exports, diagnostics, scan runtime, and LLM runtime boundaries.
* Added root confinement checks for every deletion target before it can be counted or deleted.
* Internal paths stay inside the engine and are not emitted in summaries, audit entries, errors, or verification output.

**Files Changed**:

* `apps/server/src/lib/localErasure.ts` - added local path resolver and target model.

**BQC Fixes**:

* Trust boundary enforcement: boundary ids are validated against the protocol local boundary list (`apps/server/src/lib/localErasure.ts`).
* Error information boundaries: resolver errors expose generic messages and never return configured paths (`apps/server/src/lib/localErasure.ts`).

**Verification**:

* `npm --workspace @factionos/server run typecheck` - passed.

***

### Task T006 - Add dry-run preview builder

**Started**: 2026-05-31 01:25 **Completed**: 2026-05-31 01:26 **Duration**: 1 minute

**Notes**:

* Added `buildLocalErasurePreview` for eligible, absent, skipped, manual-review, and unsupported local runtime boundaries.
* Preview output uses protocol runtime summaries with bounded item counts, labels, docs, blocked payload labels, and no-overclaim wording.
* Unsupported Worker, hosted, public replay, push, remote, analytics, workspace-file, and full trusted unified erasure boundaries are included as unsupported runtime boundaries.

**Files Changed**:

* `apps/server/src/lib/localErasure.ts` - added dry-run preview builder and verification/audit summaries.

**BQC Fixes**:

* Failure path completeness: malformed or absent local directories produce explicit absent/skipped/manual-review states instead of throwing (`apps/server/src/lib/localErasure.ts`).
* Error information boundaries: preview serializes no raw paths or payload contents (`apps/server/src/lib/localErasure.ts`).

**Verification**:

* `npm --workspace @factionos/server run typecheck` - passed.

***

### Task T007 - Add confirmed local erasure executor

**Started**: 2026-05-31 01:26 **Completed**: 2026-05-31 01:27 **Duration**: 1 minute

**Notes**:

* Added `executeLocalErasure` with exact confirmation phrase validation and required idempotency key.
* Added in-flight duplicate-key guard and bounded idempotency result cache.
* Deletes eligible boundaries independently, skips runtime/manual-review boundaries, reports partial failures, and verifies absence after deletion.
* Existing absence is treated as verified absence.

**Files Changed**:

* `apps/server/src/lib/localErasure.ts` - added confirmed executor, idempotency protection, per-boundary audit, and verification.

**BQC Fixes**:

* Duplicate action prevention: idempotency keys are cached and in-flight keys are rejected (`apps/server/src/lib/localErasure.ts`).
* Failure path completeness: failed deletion or verification is surfaced as boundary-level `failed` and summary-level `partial_failure` (`apps/server/src/lib/localErasure.ts`).
* Resource cleanup: in-flight idempotency state is removed in a `finally` block (`apps/server/src/lib/localErasure.ts`).

**Verification**:

* `npm --workspace @factionos/server run typecheck` - passed.

***

### Task T008 - Create local erasure HTTP routes

**Started**: 2026-05-31 01:27 **Completed**: 2026-05-31 01:29 **Duration**: 2 minutes

**Notes**:

* Added `POST /erasure/local/preview` and `POST /erasure/local/confirm`.
* Route inputs are schema-validated before invoking the runtime.
* Responses use no-store and no-overclaim headers while relying on the existing global local auth middleware.
* Error responses return compact codes without echoing request bodies, paths, payloads, or confirmation values.

**Files Changed**:

* `apps/server/src/routes/erasure.ts` - added local erasure preview and confirm route handlers.

**BQC Fixes**:

* Trust boundary enforcement: route validation happens before runtime execution (`apps/server/src/routes/erasure.ts`).
* Error information boundaries: route errors include stable codes only and do not echo sensitive request values (`apps/server/src/routes/erasure.ts`).

**Verification**:

* `npm --workspace @factionos/server run typecheck` - passed.

***

### Task T009 - Create browser erasure helper

**Started**: 2026-05-31 01:29 **Completed**: 2026-05-31 01:34 **Duration**: 5 minutes

**Notes**:

* Added browser-local preview and confirmed erasure helpers for settings, replay buffers, replay URL fragments, War Room hints, local auth hints, and in-memory reset hooks.
* Added idempotency result caching for browser erasure requests.
* Added compact local-server preview and confirm clients for the new server erasure routes.
* Added storage-unavailable and malformed-server-response failure states with no raw storage values in output.

**Files Changed**:

* `apps/web/src/lib/localErasure.ts` - browser erasure helper and local server route client.
* `packages/protocol/src/erasure.ts` - added CLI/web README docs paths so runtime summaries can reference package docs.

**BQC Fixes**:

* State freshness on re-entry: helper supports fresh preview from current storage state (`apps/web/src/lib/localErasure.ts`).
* Duplicate action prevention: browser idempotency keys return cached results (`apps/web/src/lib/localErasure.ts`).
* Failure path completeness: unavailable storage and bad server responses return explicit failure objects (`apps/web/src/lib/localErasure.ts`).
* Error information boundaries: summaries expose counts and labels, not storage values or URL tokens (`apps/web/src/lib/localErasure.ts`).

**Verification**:

* `npm --workspace @factionos/web run typecheck` - passed.

***

### Task T010 - Register local erasure routes

**Started**: 2026-05-31 01:34 **Completed**: 2026-05-31 01:35 **Duration**: 1 minute

**Notes**:

* Registered `erasureRouter()` after existing local auth/json middleware and before the unsupported-route catch-all.
* Route responses include local-runtime no-overclaim metadata from the route module.

**Files Changed**:

* `apps/server/src/server.ts` - mounted the local erasure router.

**BQC Fixes**:

* Trust boundary enforcement: route registration keeps erasure endpoints behind the same local auth middleware as other HTTP routes (`apps/server/src/server.ts`).

**Verification**:

* `npm --workspace @factionos/server run typecheck` - passed.

***

### Task T011 - Write server local erasure runtime tests

**Started**: 2026-05-31 01:35 **Completed**: 2026-05-31 01:37 **Duration**: 2 minutes

**Notes**:

* Added temp-directory runtime tests for dry-run, confirmation validation, idempotency, partial failure, already-absent verification, malformed spool handling, backup/log/export boundaries, unsupported boundary ids, and sensitive-output redaction.

**Files Changed**:

* `apps/server/tests/localErasure.test.ts` - local erasure runtime test coverage.

**BQC Fixes**:

* Failure path completeness: tests inject a deletion failure and assert partial-failure reporting (`apps/server/tests/localErasure.test.ts`).
* Error information boundaries: tests assert raw paths, prompts, spool payloads, exports, diagnostics, logs, backups, and tokens are absent from summaries (`apps/server/tests/localErasure.test.ts`).

**Verification**:

* `npx vitest run apps/server/tests/localErasure.test.ts apps/server/tests/erasureRoute.test.ts` - passed.

***

### Task T012 - Write server erasure route tests

**Started**: 2026-05-31 01:37 **Completed**: 2026-05-31 01:38 **Duration**: 1 minute

**Notes**:

* Added route tests for preview, confirm, malformed bodies, auth-required behavior, duplicate idempotency keys, unsupported boundaries, no-overclaim headers, and compact error mapping.

**Files Changed**:

* `apps/server/tests/erasureRoute.test.ts` - route-level local erasure tests.

**BQC Fixes**:

* Trust boundary enforcement: tests assert auth is required before preview access (`apps/server/tests/erasureRoute.test.ts`).
* Error information boundaries: tests assert invalid request payloads and idempotency values are not echoed (`apps/server/tests/erasureRoute.test.ts`).

**Verification**:

* `npx vitest run apps/server/tests/localErasure.test.ts apps/server/tests/erasureRoute.test.ts` - passed.

***

### Task T013 - Create CLI erasure client and formatter

**Started**: 2026-05-31 01:38 **Completed**: 2026-05-31 01:41 **Duration**: 3 minutes

**Notes**:

* Added loopback-only local erasure preview and confirm client helpers.
* Added timeout, unreachable, auth-required, malformed JSON, malformed shape, unavailable route, unsupported boundary, partial-failure, and compact formatting paths.
* Added in-flight idempotency guard and synthetic idempotency key generator.

**Files Changed**:

* `apps/cli/src/lib/erasureClient.js` - local erasure HTTP client, redacted formatter, and idempotency guard.

**BQC Fixes**:

* Duplicate action prevention: confirm requests with the same in-flight idempotency key are rejected client-side (`apps/cli/src/lib/erasureClient.js`).
* External dependency resilience: local server requests use loopback-only URL validation and bounded timeouts (`apps/cli/src/lib/erasureClient.js`).
* Error information boundaries: responses are compacted and sanitized before formatting (`apps/cli/src/lib/erasureClient.js`).

**Verification**:

* `node -e "import('./apps/cli/src/lib/erasureClient.js').then((m)=>console.log(typeof m.previewLocalErasure, m.LOCAL_ERASURE_CONFIRMATION_PHRASE))"` - passed.

***

### Task T014 - Add `factionos erase` command

**Started**: 2026-05-31 01:41 **Completed**: 2026-05-31 01:43 **Duration**: 2 minutes

**Notes**:

* Added a preview-by-default `runErase` command.
* Destructive execution requires the exact typed `--confirm "ERASE LOCAL FACTIONOS STATE"` phrase.
* Confirmed runs use a provided `--idempotency-key` or generate a synthetic one.
* Command output repeats no-overclaim local/browser-only wording.

**Files Changed**:

* `apps/cli/src/commands/erase.js` - CLI erase command.

**BQC Fixes**:

* Duplicate action prevention: confirmed command path always sends an idempotency key (`apps/cli/src/commands/erase.js`).
* Failure path completeness: invalid confirmation is handled locally before contacting the server (`apps/cli/src/commands/erase.js`).

**Verification**:

* `node -e "import('./apps/cli/src/commands/erase.js').then((m)=>console.log(typeof m.runErase))"` - passed.

***

### Task T015 - Wire CLI help and command dispatch

**Started**: 2026-05-31 01:43 **Completed**: 2026-05-31 01:44 **Duration**: 1 minute

**Notes**:

* Added `erase` to CLI help and command dispatch.
* Existing `init`, `install`, `start`, `launch`, `stop`, `open`, `status`, `doctor`, and `uninstall` dispatch remains unchanged.

**Files Changed**:

* `apps/cli/src/index.js` - wired erase command.

**Verification**:

* `node -e "import('./apps/cli/src/index.js').then((m)=>console.log(typeof m.main))"` - passed.

***

### Task T016 - Write CLI erasure tests

**Started**: 2026-05-31 01:44 **Completed**: 2026-05-31 01:46 **Duration**: 2 minutes

**Notes**:

* Added CLI erasure client tests for preview, confirm, non-loopback rejection, duplicate in-flight confirm keys, malformed JSON, malformed response shape, timeout, and redacted formatted output.

**Files Changed**:

* `apps/cli/tests/erasureClient.test.js` - CLI erasure client coverage.

**BQC Fixes**:

* Duplicate action prevention: tests assert duplicate in-flight confirm requests are rejected (`apps/cli/tests/erasureClient.test.js`).
* External dependency resilience: tests assert timeout and malformed local server responses have explicit failure states (`apps/cli/tests/erasureClient.test.js`).
* Error information boundaries: tests assert raw paths and token-like strings are redacted from result and formatted output (`apps/cli/tests/erasureClient.test.js`).

**Verification**:

* `npx vitest run apps/cli/tests/erasureClient.test.js` - passed.

***

### Task T017 - Create local erasure Zustand store

**Started**: 2026-05-31 01:46 **Completed**: 2026-05-31 01:49 **Duration**: 3 minutes

**Notes**:

* Added a Settings-panel state store for browser preview/result, local-server preview/result, separate confirmation phrases, in-flight guards, unavailable/error states, and drawer re-entry refresh.

**Files Changed**:

* `apps/web/src/store/useLocalErasureStore.ts` - local erasure UI state store.

**BQC Fixes**:

* Duplicate action prevention: browser and local confirm actions return early while already in flight (`apps/web/src/store/useLocalErasureStore.ts`).
* State freshness on re-entry: `openPanel` resets transient state and refreshes previews (`apps/web/src/store/useLocalErasureStore.ts`).
* Failure path completeness: local-server unavailable and invalid confirmation paths produce explicit UI state (`apps/web/src/store/useLocalErasureStore.ts`).

**Verification**:

* `npm --workspace @factionos/web run typecheck` - passed.

***

### Task T018 - Create Settings drawer local erasure panel

**Started**: 2026-05-31 01:49 **Completed**: 2026-05-31 01:53 **Duration**: 4 minutes

**Notes**:

* Added a Settings-compatible local erasure panel with loading, unavailable, preview, typed confirmation, in-flight, completed, partial-failure, unsupported boundary, and verification/count states.
* Browser and local server erasure use separate confirmation phrases and controls.
* Browser erasure reset hooks refresh in-memory cockpit, replay, settings, and War Room context without writing deleted storage keys back.

**Files Changed**:

* `apps/web/src/components/LocalErasurePanel.tsx` - local/browser erasure panel.
* `apps/web/src/lib/localErasure.ts` - added persisted faction hint to browser settings cleanup.

**BQC Fixes**:

* Accessibility and platform compliance: inputs/buttons have labels and disabled states (`apps/web/src/components/LocalErasurePanel.tsx`).
* Duplicate action prevention: confirm buttons disable while corresponding action is in flight (`apps/web/src/components/LocalErasurePanel.tsx`).
* State freshness on re-entry: panel calls store `openPanel` on mount and resets on unmount (`apps/web/src/components/LocalErasurePanel.tsx`).

**Verification**:

* `npm --workspace @factionos/web run typecheck` - passed.

***

### Task T019 - Mount local erasure panel in Settings

**Started**: 2026-05-31 01:53 **Completed**: 2026-05-31 01:54 **Duration**: 1 minute

**Notes**:

* Mounted `LocalErasurePanel` in the Settings drawer after codebase scan controls and before the existing dev/data controls.
* Existing audio, notification, scan, replay, reset, analytics, theme, and faction controls remain intact.

**Files Changed**:

* `apps/web/src/components/SettingsDrawer.tsx` - mounted the local erasure panel.

**Verification**:

* `npm --workspace @factionos/web run typecheck` - passed.

***

### Task T020 - Write browser erasure helper tests

**Started**: 2026-05-31 01:54 **Completed**: 2026-05-31 01:56 **Duration**: 2 minutes

**Notes**:

* Added browser helper tests for localStorage cleanup, URL fragment cleanup, War Room hint cleanup, settings/replay reset hooks, storage-unavailable handling, idempotency, invalid confirmation, and redacted summaries.

**Files Changed**:

* `apps/web/tests/localErasure.test.ts` - browser erasure helper coverage.

**BQC Fixes**:

* State freshness on re-entry: tests verify previews derive from current storage state (`apps/web/tests/localErasure.test.ts`).
* Error information boundaries: tests assert raw tokens and replay payloads are absent from summaries (`apps/web/tests/localErasure.test.ts`).

**Verification**:

* `npx vitest run apps/web/tests/localErasure.test.ts` - passed.

***

### Task T021 - Write LocalErasurePanel tests

**Started**: 2026-05-31 01:56 **Completed**: 2026-05-31 01:58 **Duration**: 2 minutes

**Notes**:

* Added UI tests for focus behavior, typed confirmation, disabled while pending controls, partial failure, completed browser cleanup, unavailable server state, unsupported copy, and state reset on close/reopen.

**Files Changed**:

* `apps/web/tests/LocalErasurePanel.test.tsx` - UI tests for the local erasure panel.

**BQC Fixes**:

* Accessibility and platform compliance: tests assert focus lands on the refresh control after mount (`apps/web/tests/LocalErasurePanel.test.tsx`).
* Duplicate action prevention: tests assert local confirm is disabled and shows pending copy while the request is unresolved (`apps/web/tests/LocalErasurePanel.test.tsx`).
* State freshness on re-entry: tests assert transient confirmation state resets on unmount/reopen (`apps/web/tests/LocalErasurePanel.test.tsx`).

**Verification**:

* `npx vitest run apps/web/tests/LocalErasurePanel.test.tsx` - passed.

***

### Task T022 - Update local/browser erasure docs

**Started**: 2026-05-31 01:58 **Completed**: 2026-05-31 02:03 **Duration**: 5 minutes

**Notes**:

* Updated stable docs and package READMEs for local/browser erasure behavior, no raw-output guarantees, explicit confirmation, local auth boundary, manual-review boundaries, partial-failure states, and remaining Worker/hosted/full trusted erasure limitations.

**Files Changed**:

* `docs/privacy-and-security.md` - documented Session 03 local/browser runtime and controls.
* `docs/release.md` - added Session 03 release evidence and limitations.
* `docs/api/README_api.md` - documented local erasure routes and no-overclaim API behavior.
* `apps/cli/README_cli.md` - documented `factionos erase` preview/confirm behavior.
* `apps/web/README_web.md` - documented Settings local erasure panel and browser boundaries.
* `apps/server/README_server.md` - documented server erasure runtime scope and sensitive-output rules.

**BQC Fixes**:

* Error information boundaries: docs explicitly prohibit raw paths, prompts, logs, backups, exports, diagnostics, spool payloads, tokens, request bodies, and idempotency keys in output.
* Contract alignment: docs distinguish local/browser erasure from Worker, hosted, workspace-file, public replay, analytics, push, remote, and full trusted unified erasure.

***

### Task T023 - Run focused tests and affected typechecks

**Started**: 2026-05-31 02:03 **Completed**: 2026-05-31 02:05 **Duration**: 2 minutes

**Notes**:

* Ran focused protocol, server, CLI, and web erasure test coverage.
* Ran affected protocol, server, and web workspace typechecks.

**Files Changed**:

* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md` - recorded validation results.

**Verification**:

* `npx vitest run packages/protocol/tests/erasure.test.ts apps/server/tests/localErasure.test.ts apps/server/tests/erasureRoute.test.ts apps/cli/tests/erasureClient.test.js apps/web/tests/localErasure.test.ts apps/web/tests/LocalErasurePanel.test.tsx` - passed, 28 tests.
* `npm --workspace @factionos/protocol run typecheck` - passed.
* `npm --workspace @factionos/server run typecheck` - passed.
* `npm --workspace @factionos/web run typecheck` - passed.

***

### Task T024 - Run docs/no-overclaim and file hygiene validation

**Started**: 2026-05-31 02:05 **Completed**: 2026-05-31 02:08 **Duration**: 3 minutes

**Notes**:

* Reviewed changed docs and user-facing runtime copy for trusted-erasure wording.
* Added formatter validation after applying scoped Biome formatting to the touched code/test files.
* Confirmed session-owned text, code, docs, and spec files contain ASCII-only content and no CRLF line endings.
* Confirmed whitespace validation is clean.

**Files Changed**:

* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/tasks.md` - marked T024 complete and updated progress.
* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md` - recorded T024 quality gates.

**BQC Fixes**:

* Error information boundaries: no-overclaim review confirms added copy keeps `P06-S07-ERASURE` open and says Worker, hosted, public replay, analytics, push, remote, workspace-file, production-hosted, and full trusted unified erasure remain unavailable.
* Static analysis and formatting: Biome formatting was applied to touched code/test files, then rechecked successfully.

**Verification**:

* `npx biome format --write ...` - passed, formatted 17 touched code/test files and fixed 9 files.
* `npx vitest run packages/protocol/tests/erasure.test.ts apps/server/tests/localErasure.test.ts apps/server/tests/erasureRoute.test.ts apps/cli/tests/erasureClient.test.js apps/web/tests/localErasure.test.ts apps/web/tests/LocalErasurePanel.test.tsx` - passed, 28 tests.
* `npm --workspace @factionos/protocol run typecheck` - passed.
* `npm --workspace @factionos/server run typecheck` - passed.
* `npm --workspace @factionos/web run typecheck` - passed.
* `npx biome format ...` - passed, no fixes required.
* Scoped ASCII scan across session-owned text/code/docs/spec files - passed, no output.
* Scoped CRLF scan across session-owned text/code/docs/spec files - passed, no output.
* Scoped trailing-whitespace scan across session-owned text/code/docs/spec files - passed, no output.
* `git diff --check` - passed.
* `git diff -- docs/privacy-and-security.md docs/release.md docs/api/README_api.md apps/cli/README_cli.md apps/web/README_web.md apps/server/README_server.md apps/web/src/components/LocalErasurePanel.tsx apps/cli/src/commands/erase.js apps/server/src/routes/erasure.ts packages/protocol/src/erasure.ts | rg -n "^\\+.*(trusted unified erasure|trusted erasure|full trusted|P06-S07-ERASURE|Worker Durable|hosted|public replay|workspace)"` - reviewed added limitation copy; no overclaim found.

**Residual Risks**:

* `P06-S07-ERASURE` remains open; Session 03 does not claim full trusted unified erasure.
* Worker Durable Object erasure, hosted account/storage/analytics deletion, public replay takedown, push deletion, remote-access deletion, broad workspace-file deletion, and production-hosted validation remain out of scope.
* Manual-review boundaries such as local backups and malformed spool recovery remain explicit manual-review or narrow cleanup paths, not trusted erasure proof.
* Unrelated untracked binary music assets are present in the worktree and were not rewritten or treated as session text artifacts.

### Task T025 - Validate checklist and handoff readiness

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

**Notes**:

* Confirmed the task checklist has all 25 tasks marked complete and the completion checklist is checked.
* Confirmed implementation notes include task-by-task changes, verification commands, BQC fixes, and residual risks.
* Confirmed T024 records ASCII, LF, formatting, diff, and no-overclaim evidence.
* Session is ready for the validate workflow step, while `P06-S07-ERASURE` remains open for later Phase 08 work.

**Files Changed**:

* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/tasks.md` - marked T025 and completion checklist complete; updated progress and next step.
* `.spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md` - recorded final handoff readiness.

**BQC Fixes**:

* Contract alignment: checklist, implementation notes, and next-step copy now all point to validate as the next workflow action.
* Error information boundaries: final handoff preserves the limitation that Session 03 does not close full trusted unified erasure.

**Verification**:

* `rg -n "^- \\[ \\]" .spec_system/specs/phase08-session03-local-erasure-runtime-and-controls/tasks.md` - passed, no output.
* `git diff --check` - passed.
* Scoped ASCII scan across session-owned text/code/docs/spec files - passed, no output.
* Scoped CRLF scan across session-owned text/code/docs/spec files - passed, no output.
* Scoped trailing-whitespace scan across session-owned text/code/docs/spec files - passed, no output.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase08-session03-local-erasure-runtime-and-controls/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
