session dir exists; monorepo is true. * Evidence: Analyzer reported Phase 22 in progress with Session 08 incomplete and Session 01-07 complete. * Command/check: `bash /home/aiwithapex/.codex/plugins/cache/apexdev/apex-spec/2.2.18-codex/skills/apex-spec/scripts/check-prereqs.sh --json --env --package apps/web` * Result: PASS - Spec system, jq, git, package directory, and package manifest are available. * Evidence: Overall result was `pass` with npm 11.16.0 detected. * Command/check: `sed -n '1,260p' .spec_system/specs/phase22-session07-honesty-regression-tests/validation.md` * Result: PASS - Session 07 validation result is PASS. * Evidence: Validation summary lists focused tests 59/59 passed and root suite 3206/3207 passed with 1 skipped. * Command/check: `sed -n '1,260p' .spec_system/PRD/phase_22/PRD_phase_22.md` * Result: PASS - Phase 22 PRD shows Session 08 as the only remaining session. * Evidence: Progress tracker lists Sessions 01-07 complete and Session 08 not started. * UI product-surface check: N/A - No user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T002 - Inspect browser erasure boundaries **Started**: 2026-07-05 13:21 **Completed**: 2026-07-05 13:22 **Duration**: 1 minute **Notes**: * Confirmed protocol browser boundary ids already include settings, replay fragments, War Room hints, auth hints, and runtime memory. * Confirmed `localErasure.ts` maps storage keys to existing browser boundaries and builds summaries from counts only. **Files Changed**: * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded boundary inspection evidence. **Verification**: * Command/check: `sed -n '1,260p' packages/protocol/src/erasure.ts` * Result: PASS - Browser boundary ids are protocol-owned and no projection-specific boundary exists. * Evidence: Browser ids include `browser_settings`, `browser_replay_fragments`, `browser_war_room_hints`, `browser_auth_hints`, and `browser_runtime_memory`. * Command/check: `sed -n '1,320p' apps/web/src/lib/localErasure.ts && sed -n '320,680p' apps/web/src/lib/localErasure.ts` * Result: PASS - Web cleanup is driven by `BROWSER_BOUNDARY_PLANS`; summaries contain counts, statuses, docs, and blocked payload labels. * Evidence: `executeBrowserBoundary()` removes listed storage keys, duplicate confirmations return cached summaries, and raw payloads are not included. * UI product-surface check: N/A - Inspection-only task; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T003 - Inspect projection storage, reset, and docs **Started**: 2026-07-05 13:22 **Completed**: 2026-07-05 13:23 **Duration**: 1 minute **Notes**: * Confirmed `GAME_PROJECTION_STORAGE_KEY` is the single projection storage key and is reused by projection persistence tests. * Confirmed `resetToSeed()` clears pending projection writes, removes persisted projection storage, and resets in-memory projection state. * Identified docs that need narrow reconciliation: technical projection doc, change log, implemented phase ledger, web README, and privacy docs. **Files Changed**: * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded projection and docs inspection evidence. **Verification**: * Command/check: `rg -n "GAME_PROJECTION_STORAGE_KEY|removePersistedGameProjection|resetToSeed|localStorage" apps/web/src/lib/gameProjection.ts apps/web/src/store/useGameStore.ts apps/web/tests/gameProjectionStore.test.ts apps/web/tests/localErasure.test.ts` * Result: PASS - Projection storage key, persistence helpers, reset path, and existing reset tests were found. * Evidence: `GAME_PROJECTION_STORAGE_KEY` is `"factionos-game-v1"`; `resetToSeed()` calls `removePersistedGameProjection()`. * Command/check: `sed -n '500,920p' apps/web/tests/gameProjectionStore.test.ts` * Result: PASS - Existing tests already prove reset removes browser projection storage and clears pending writes. * Evidence: `useGameStore reset projection memory` has focused assertions for storage absence after reset. * Command/check: `rg -n "suggestion_update|attention|pendingLinks|campLinks|erasure|trusted|factionos-game-v1|Phase 22" docs/game-design/10-technical-design-and-game-projection.md docs/game-design/11-open-questions-and-change-log.md docs/game-design/14-implemented-phases.md apps/web/README_web.md docs/privacy-and-security.md` * Result: PASS - Older docs text and local erasure wording needing source-backed reconciliation were identified. * Evidence: Technical doc still describes `suggestion_update` camp reconciliation while source implements a Phase 22 no-op. * UI product-surface check: N/A - Inspection-only task; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T004 - Add projection key to browser erasure inventory **Started**: 2026-07-05 13:23 **Completed**: 2026-07-05 13:24 **Duration**: 1 minute **Notes**: * Imported `GAME_PROJECTION_STORAGE_KEY` and added it to the existing browser settings/app-state cleanup plan. * Preserved protocol browser boundary ids and existing idempotency cache behavior. **Files Changed**: * `apps/web/src/lib/localErasure.ts` - Added projection storage key inventory under the existing browser storage boundary plan. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'node --version && npm test -- apps/web/tests/localErasure.test.ts'` * Result: PASS - Focused local erasure tests passed under Node 26.2.0. * Evidence: 1 test file passed; 4 tests passed. * Command/check: `sed -n '1,120p' apps/web/src/lib/localErasure.ts` * Result: PASS - No new protocol boundary id was added. * Evidence: `browser_settings` now includes settings keys plus `GAME_PROJECTION_STORAGE_KEY`. * UI product-surface check: N/A - No user-facing UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Contract alignment: Reused `GAME_PROJECTION_STORAGE_KEY` instead of duplicating the literal storage key (`apps/web/src/lib/localErasure.ts`). *** ### Task T005 - Extend browser erasure preview coverage **Started**: 2026-07-05 13:24 **Completed**: 2026-07-05 13:25 **Duration**: 1 minute **Notes**: * Seeded `localStorage["factionos-game-v1"]` through the shared projection key constant. * Asserted preview counts the projection key without leaking the seeded raw value. **Files Changed**: * `apps/web/tests/localErasure.test.ts` - Added projection storage seeding and preview redaction assertions. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/localErasure.test.ts'` * Result: PASS - Focused local erasure tests passed. * Evidence: 1 test file passed; 4 tests passed. * Command/check: `sed -n '1,130p' apps/web/tests/localErasure.test.ts` * Result: PASS - Preview assertions cover projection-key counting and raw-value redaction. * Evidence: `browser_settings` item count is asserted as 4 and preview JSON excludes `raw projection payload`. * UI product-surface check: N/A - No user-facing UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Error information boundaries: Added a raw projection payload sentinel to prove erasure summaries do not expose browser storage values (`apps/web/tests/localErasure.test.ts`). *** ### Task T006 - Extend browser erasure confirmation coverage **Started**: 2026-07-05 13:25 **Completed**: 2026-07-05 13:26 **Duration**: 1 minute **Notes**: * Added explicit confirmation assertions that projection storage is removed. * Added duplicate idempotency assertions proving a repeated key returns the cached result and does not execute another destructive pass. **Files Changed**: * `apps/web/tests/localErasure.test.ts` - Added projection confirmation removal and duplicate idempotency assertions. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/localErasure.test.ts'` * Result: PASS - Focused local erasure tests passed. * Evidence: 1 test file passed; 4 tests passed. * Command/check: `sed -n '1,130p' apps/web/tests/localErasure.test.ts` * Result: PASS - Confirmation removes `GAME_PROJECTION_STORAGE_KEY`; duplicate confirmation preserves restored storage values. * Evidence: Test asserts projection storage is null after confirmation and unchanged after cached duplicate confirmation. * UI product-surface check: N/A - No user-facing UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * Duplicate action prevention: Extended idempotency coverage for projection storage cleanup (`apps/web/tests/localErasure.test.ts`). * State freshness on re-entry: Confirmed browser erasure removes derived projection storage so later store creation cannot hydrate stale projection state. ### Task T007 - Verify reset projection storage coverage **Started**: 2026-07-05 13:26 **Completed**: 2026-07-05 13:27 **Duration**: 1 minute **Notes**: * Extended the existing reset test to import a fresh store after reset, proving re-entry hydrates seed projection state instead of stale persisted projection storage. * No production store change was required because `resetToSeed()` already clears pending projection writes and removes `GAME_PROJECTION_STORAGE_KEY`. **Files Changed**: * `apps/web/tests/gameProjectionStore.test.ts` - Added fresh-store re-entry assertion after reset. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/gameProjectionStore.test.ts'` * Result: PASS - Focused store projection tests passed. * Evidence: 1 test file passed; 21 tests passed. * Command/check: `sed -n '860,895p' apps/web/tests/gameProjectionStore.test.ts` * Result: PASS - Reset test proves in-memory reset, storage removal, and fresh-store re-entry state. * Evidence: Assertions compare both active and fresh store projection state to `createInitialGameProjection(LATER_NOW)`. * UI product-surface check: N/A - No user-facing UI changed. * UI craft check: N/A - No UI changed. **BQC Fixes**: * State freshness on re-entry: Added fresh-store import after reset to prove stale projection storage cannot rehydrate (`apps/web/tests/gameProjectionStore.test.ts`). *** ### Task T008 - Update technical game projection doc **Started**: 2026-07-05 13:27 **Completed**: 2026-07-05 13:28 **Duration**: 1 minute **Notes**: * Reconciled the event map with Phase 22 shipped behavior for `suggestion_update`, `mission_start`, and shared gate attention. * Added a Phase 22 foundation note covering persisted attention refs, dormant camp links, browser-local projection erasure, reset cleanup, and trusted-erasure no-claim. **Files Changed**: * `docs/game-design/10-technical-design-and-game-projection.md` - Updated technical design wording for shipped Phase 22 choices. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `rg -n "Phase 22 shipped behavior|Phase 22 shipped foundation notes|factionos-game-v1|trusted unified erasure|command_center_permission_update|Dormant unless" docs/game-design/10-technical-design-and-game-projection.md` * Result: PASS - Required source-backed closeout wording is present. * Evidence: Matches cover `suggestion_update` no-op, shared gate attention, dormant camp links, projection storage, and no-claim erasure language. * Command/check: `rg -n "reduceSuggestionUpdate|commandCenterPermission|recordProjectionPendingLink|removePersistedGameProjection|GAME_PROJECTION_STORAGE_KEY" apps/web/src/lib/gameProjection.ts apps/web/src/store/useGameStore.ts apps/web/src/lib/localErasure.ts` * Result: PASS - Source anchors support the doc update. * Evidence: Source implements snapshot no-op, shared gate refs, pending link recording, reset removal, and projection key inventory. * UI product-surface check: N/A - Documentation-only task; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T009 - Update change log and implemented phase ledger **Started**: 2026-07-05 13:28 **Completed**: 2026-07-05 13:29 **Duration**: 1 minute **Notes**: * Ran focused closeout validation before updating ledger wording. * Added Phase 22 closeout implementation evidence without claiming final spec-system workflow completion. **Files Changed**: * `docs/game-design/11-open-questions-and-change-log.md` - Added Phase 22 closeout implementation change-log entry. * `docs/game-design/14-implemented-phases.md` - Added Projection Foundation closeout evidence and pending workflow gate status. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/gameProjection.test.ts apps/web/tests/gameProjectionStore.test.ts apps/web/tests/replayPersist.test.ts apps/web/tests/localErasure.test.ts'` * Result: PASS - Focused closeout validation passed. * Evidence: 4 test files passed;

no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T010 - Review stable web and privacy docs **Started**: 2026-07-05 13:29 **Completed**: 2026-07-05 13:30 **Duration**: 1 minute **Notes**: * Updated stable docs where browser-local erasure wording diverged from the new projection cleanup behavior. * Preserved no-claim wording for Worker, hosted, workspace, public replay, analytics, push, remote, and full trusted erasure boundaries. **Files Changed**: * `apps/web/README_web.md` - Added derived game projection storage to browser-local erasure wording. * `docs/privacy-and-security.md` - Added derived projection storage to browser-local cleanup and data inventory wording. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded task evidence. **Verification**: * Command/check: `rg -n "derived game projection storage|factionos-game-v1|clears derived projection storage|trusted erasure claims unavailable" apps/web/README_web.md docs/privacy-and-security.md` * Result: PASS - Stable docs name projection storage cleanup and preserve no-claim wording. * Evidence: Matches cover web README cleanup bullets and privacy data inventory/local erasure safeguards. * Command/check: `rg -n "GAME_PROJECTION_STORAGE_KEY|BROWSER_GAME_PROJECTION_STORAGE_KEYS" apps/web/src/lib/gameProjection.ts apps/web/src/lib/localErasure.ts` * Result: PASS - Documentation wording matches source constants. * Evidence: Projection key is shared into browser erasure storage key inventory. * UI product-surface check: N/A - Documentation-only task; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T011 - Record implementation evidence and no-claim notes **Started**: 2026-07-05 13:30 **Completed**: 2026-07-05 13:31 **Duration**: 1 minute **Notes**: * Added a session evidence ledger for code, test, and documentation closeout work completed so far. * Recorded no-claim boundaries so validation does not overstate the browser-local projection cleanup. **Files Changed**: * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Added evidence and no-claim notes. **Verification**: * Command/check: `rg -n "Session Evidence Ledger|No-Claim Boundary Notes|factionos-game-v1|trusted unified erasure" .spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` * Result: PASS - Evidence and no-claim sections are present. * Evidence: Notes name the projection key cleanup and trusted-erasure no-claim boundary. * UI product-surface check: N/A - Notes-only task; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T012 - Run focused projection reducer validation **Started**: 2026-07-05 13:31 **Completed**: 2026-07-05 13:32 **Duration**: 1 minute **Notes**: * Ran the required focused reducer validation command after code and docs updates. **Files Changed**: * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded validation evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/gameProjection.test.ts'` * Result: PASS - Focused projection reducer tests passed. * Evidence: 1 test file passed;

16 tests passed. * UI product-surface check: N/A - Test-only validation; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T014 - Run broadened store regressions **Started**: 2026-07-05 13:33 **Completed**: 2026-07-05 13:34 **Duration**: 1 minute **Notes**: * Ran broadened store regressions because projection store test coverage changed and local erasure touches reset-adjacent browser state. **Files Changed**: * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded validation evidence. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/gameProjectionStore.test.ts apps/web/tests/replayBuffer.test.ts apps/web/tests/questBoardStore.test.ts apps/web/tests/orchestrationStore.test.ts apps/web/tests/commandCenterStore.test.ts'` * Result: PASS - Broadened store regressions passed. * Evidence: 5 test files passed; 60 tests passed. * UI product-surface check: N/A - Test-only validation; no user-facing UI changed. * UI craft check: N/A - No UI changed. *** ### Task T015 - Run typecheck, Biome, ASCII/LF, and closeout readiness **Started**: 2026-07-05 13:34 **Completed**: 2026-07-05 13:36 **Duration**: 2 minutes **Notes**: * Ran web typecheck under the project Node 26.2.0 baseline. * Ran changed-file Biome through the local binary after npm 11 rejected the first `npm exec` argument form. * Normalized touched markdown files to ASCII where older game-design glyphs would have failed the session gate. * Confirmed touched files use LF line endings and the diff has no whitespace errors. **Files Changed**: * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md` - Recorded closeout evidence. * `.spec_system/specs/phase22-session08-erasure-docs-and-validation/tasks.md` - Marked final task and completion checklist. * `docs/game-design/10-technical-design-and-game-projection.md` - Mechanically normalized touched doc to ASCII and replaced a damaged legacy flow diagram with ASCII text. * `docs/game-design/11-open-questions-and-change-log.md` - Mechanically normalized touched doc to ASCII. * `apps/web/README_web.md`, `docs/game-design/14-implemented-phases.md`, `docs/privacy-and-security.md` - Confirmed ASCII/LF after source-backed doc updates. **Verification**: * Command/check: `npx -y -p node@26.2.0 -c 'npm --workspace @factionos/web run typecheck'` * Result: PASS - Web package typecheck passed. * Evidence: `tsc -b --noEmit` completed with exit code 0. * Command/check: `npx -y -p node@26.2.0 -c './node_modules/.bin/biome check apps/web/src/lib/localErasure.ts apps/web/tests/localErasure.test.ts apps/web/tests/gameProjectionStore.test.ts apps/web/README_web.md docs/game-design/10-technical-design-and-game-projection.md docs/game-design/11-open-questions-and-change-log.md docs/game-design/14-implemented-phases.md docs/privacy-and-security.md .spec_system/specs/phase22-session08-erasure-docs-and-validation/spec.md .spec_system/specs/phase22-session08-erasure-docs-and-validation/tasks.md .spec_system/specs/phase22-session08-erasure-docs-and-validation/implementation-notes.md'` * Result: PASS - Changed-file Biome check passed for recognized files. * Evidence: Biome checked 3 files and applied no fixes. * Command/check: `LC_ALL=C grep -n '[^[:print:][:space:]]' ...; grep -n $'\r' ...` * Result: PASS - Touched files are ASCII and LF. * Evidence: Combined check printed `ASCII/LF PASS`. * Command/check: `git diff --check` * Result: PASS - No whitespace errors. * Evidence: Command exited 0 with no output. * UI product-surface check: N/A - No user-facing UI changed. * UI craft check: N/A - No UI changed. *** ## Session Evidence Ledger * Browser-local erasure inventory: `apps/web/src/lib/localErasure.ts` imports `GAME_PROJECTION_STORAGE_KEY` and includes it in the existing browser settings/app-state storage cleanup plan. * Browser-local erasure tests: `apps/web/tests/localErasure.test.ts` seeds `localStorage["factionos-game-v1"]`, proves preview counts it without raw-value leakage, proves confirmation removes it, and proves duplicate idempotency remains cached. * Store reset tests: `apps/web/tests/gameProjectionStore.test.ts` proves `resetToSeed()` removes `localStorage["factionos-game-v1"]` and fresh store re-entry starts from seed projection state. * Documentation: game-design, web README, and privacy docs now describe Phase 22 shipped behavior for projection erasure, `suggestion_update` no-op, shared gate attention, persisted attention refs, dormant camp links, and no-claim boundaries. * Focused validation to date: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/gameProjection.test.ts apps/web/tests/gameProjectionStore.test.ts apps/web/tests/replayPersist.test.ts apps/web/tests/localErasure.test.ts'` passed 4 files and 63 tests. * Closeout checks: web typecheck passed, changed-file Biome passed, ASCII/LF validation passed, and `git diff --check` passed. ## No-Claim Boundary Notes * Browser-local erasure now removes the derived projection key `localStorage["factionos-game-v1"]`; it does not prove trusted unified erasure across logs, backups, archives, exports, workspace files, Worker Durable Object state, hosted identity, hosted storage, analytics, push, remote access, or public replay. * `resetToSeed()` removes browser projection storage and resets in-memory projection state; it is not a broad erasure workflow. * `suggestion_update` remains an explicit Phase 22 no-op for projection camps; Quest Board remains source of truth until a later scoped reconciliation phase. * Camp links remain dormant unless a caller records real `campId`, `heroId`, and verbatim `prompt` values before a matching `mission_start`. *** ## Checkpoints ### Checkpoint After T006 * Test/build command: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/localErasure.test.ts'` * Result: PASS - 1 test file passed; 4 tests passed. * Scope check: Re-read Session 08 success criteria and confirmed work remains inside browser-local erasure and docs closeout scope. * Next task: T007 - verify or extend `resetToSeed()` projection storage removal coverage. ### Checkpoint After T010 * Test/build command: `npx -y -p node@26.2.0 -c 'npm test -- apps/web/tests/gameProjection.test.ts apps/web/tests/gameProjectionStore.test.ts apps/web/tests/replayPersist.test.ts apps/web/tests/localErasure.test.ts'` * Result: PASS - 4 test files passed; 63 tests passed. * Scope check: Re-read Session 08 success criteria and confirmed remaining work is evidence capture plus required closeout validation commands. * Next task: T011 - record implementation evidence, validation outputs, and no-claim boundary notes. --- # Agent Instructions This documentation is published with GitBook.
