Session Start **Environment verified**: * [x] Prerequisites confirmed with `.spec_system/scripts/check-prereqs.sh --json --env` * [x] Tools available: npm, Node workspace, jq, git * [x] Directory structure ready * [x] Database not configured for this project; no migration service required *** ### Task T001 - Verify hosted persistence prerequisites **Started**: 2026-05-30 10:06 **Completed**: 2026-05-30 10:07 **Duration**: 1 minute **Notes**: * Confirmed active session from `.spec_system/scripts/analyze-project.sh --json`. * Reviewed Phase 07 routing matrix, hosted payload privacy blocklist, Sessions 01-03 stubs, hosted services baseline, hosted identity guardrail artifact, ADRs, and existing replay/export/War Room redaction references. * Confirmed Session 04 owns hosted persistence eligibility, public replay requirements, local-only fallback, disabled-default posture, and Phase 08 erasure handoff without adding databases, buckets, uploads, public replay routes, or trusted erasure claims. **Files Changed**: * `.spec_system/specs/phase07-session04-hosted-persistence-and-public-replay-boundaries/implementation-notes.md` - Recorded prerequisite verification evidence. *** ### Task T002 - Create implementation evidence notes shell **Started**: 2026-05-30 10:07 **Completed**: 2026-05-30 10:07 **Duration**: 1 minute **Notes**: * Created the implementation evidence shell with environment evidence, progress table, task log, and placeholders for command evidence and residual risks. **Files Changed**: * `.spec_system/specs/phase07-session04-hosted-persistence-and-public-replay-boundaries/implementation-notes.md` - Created session notes shell. *** ### Task T003 - Create hosted persistence and public replay boundary artifact **Started**: 2026-05-30 10:07 **Completed**: 2026-05-30 10:08 **Duration**: 1 minute **Notes**: * Added the source-backed Session 04 boundary artifact with status vocabulary, data eligibility categories, blocked payload labels, server-mediated storage requirements, public replay hosting requirements, diagnostics rules, unsupported claims, local-only fallback, and Phase 08 erasure handoff. * Kept wording scoped to planned, unavailable, disabled, local-only, and unsupported states. **Files Changed**: * `.spec_system/PRD/phase_07/hosted_persistence_public_replay_boundaries.md` - Added hosted persistence and public replay guardrail baseline. *** ### Task T004 - Create hosted persistence protocol contracts **Started**: 2026-05-30 10:08 **Completed**: 2026-05-30 10:11 **Duration**: 3 minutes **Notes**: * Added protocol-owned hosted persistence and public replay status vocabulary, eligibility decisions, data classifications, blocked payload labels, public replay requirements, docs paths, unsupported claims, type guards, counts, and bounded summary builder. * Summary output is deterministic, status-only, and keeps hosted persistence required, storage runtime, upload endpoint, storage client, account-backed persistence, and public replay hosting disabled or not shipped. **Files Changed**: * `packages/protocol/src/hostedPersistence.ts` - Added shared guardrail contracts and summary helpers. **BQC Fixes**: * Contract alignment: Kept server/web-facing summary fields explicit and exhaustive for planned/unavailable diagnostics. * Error information boundaries: Summary builder exposes labels, docs paths, booleans, and counts only. *** ### Task T005 - Add protocol hosted persistence tests **Started**: 2026-05-30 10:09 **Completed**: 2026-05-30 10:11 **Duration**: 2 minutes **Notes**: * Added tests for status and eligibility vocabulary, storage classifications, public replay requirements, blocked payload labels, unsupported claims, uniqueness, bounded summary shape, and negative raw-value assertions. * Focused protocol test passed. **Files Changed**: * `packages/protocol/tests/hostedPersistence.test.ts` - Added hosted persistence contract tests. **BQC Fixes**: * Contract alignment: Tests verify count totals and exported array uniqueness. * Error information boundaries: Tests assert synthetic storage secrets, service-role keys, account ids, prompts, terminal output, and local paths are absent from serialized summaries. *** ### Task T006 - Create hosted persistence diagnostics builder **Started**: 2026-05-30 10:11 **Completed**: 2026-05-30 10:13 **Duration**: 2 minutes **Notes**: * Added a local diagnostics builder that wraps the protocol summary and normalizes status to `planned` or `unavailable`. * The builder does not read env values, request bodies, replay data, exports, logs, backups, account ids, tokens, local paths, or payload content. **Files Changed**: * `apps/server/src/lib/hostedPersistence.ts` - Added hosted persistence diagnostics builder and status normalization. **BQC Fixes**: * Error information boundaries: Diagnostics expose protocol labels and booleans only. * Contract alignment: Builder consumes the shared protocol summary. *** ### Task T007 - Wire hosted persistence diagnostics route **Started**: 2026-05-30 10:11 **Completed**: 2026-05-30 10:13 **Duration**: 2 minutes **Notes**: * Added `GET /diagnostics/hosted-persistence` to the existing diagnostics router. * The route inherits global local bearer auth, CORS, rate-limit, and JSON body limits from the server setup, and returns a compact 503 envelope if diagnostics fail. * Added server option plumbing for the planned/unavailable diagnostics status. **Files Changed**: * `apps/server/src/routes/diagnostics.ts` - Added hosted persistence diagnostics route. * `apps/server/src/server.ts` - Added hosted persistence diagnostics option plumbing. **BQC Fixes**: * Failure path completeness: Route catches builder failure and returns a bounded unavailable diagnostic error. * Error information boundaries: Error envelope does not echo request bodies or raw values. *** ### Task T008 - Add server hosted persistence diagnostics tests **Started**: 2026-05-30 10:11 **Completed**: 2026-05-30 10:13 **Duration**: 2 minutes **Notes**: * Added route tests for planned posture, CORS inheritance, local bearer auth inheritance, unavailable status, no storage/public replay activation, synthetic sensitive-value non-leakage, and unsupported method body non-echo. * Initial focused run failed because the protocol barrel had not exported the new module yet. Added the barrel export and reran successfully. **Files Changed**: * `apps/server/tests/hostedPersistenceDiagnostics.test.ts` - Added hosted persistence diagnostics route coverage. **BQC Fixes**: * Trust boundary enforcement: Auth inheritance is tested when `FACTIONOS_AUTH_TOKEN` equivalent test config is set. * Error information boundaries: Tests assert synthetic tokens, account ids, prompt text, replay/export/log/backup strings, and local paths are absent from diagnostics. *** ### Task T011 - Export hosted persistence contracts from protocol barrel **Started**: 2026-05-30 10:13 **Completed**: 2026-05-30 10:13 **Duration**: 1 minute **Notes**: * Exported hosted persistence contracts from the protocol barrel so server and web consumers can follow the existing `@factionos/protocol` import pattern. **Files Changed**: * `packages/protocol/src/index.ts` - Added `hostedPersistence` barrel export. **BQC Fixes**: * Contract alignment: Server diagnostics now consume the same public protocol surface as existing hosted config and hosted identity modules. *** ### Task T009 - Create browser hosted persistence helper **Started**: 2026-05-30 10:13 **Completed**: 2026-05-30 10:15 **Duration**: 2 minutes **Notes**: * Added browser helper state for planned/unavailable hosted persistence, disabled public replay hosting, local URL-fragment replay fallback, replay caps, docs, blocked labels, and unsupported claims. * Kept account UI, storage clients, upload endpoints, hosted storage, public replay hosting, and account-backed persistence explicitly unavailable or false. **Files Changed**: * `apps/web/src/lib/hostedPersistence.ts` - Added hosted persistence and public replay browser helpers. **BQC Fixes**: * Contract alignment: Browser helper consumes protocol-owned labels and replay-link caps. * Accessibility and platform compliance: Helper copy is bounded and explicit for future UI state, without adding UI controls in this task. *** ### Task T010 - Add web hosted persistence helper tests **Started**: 2026-05-30 10:14 **Completed**: 2026-05-30 10:15 **Duration**: 1 minute **Notes**: * Added tests for planned and unavailable browser posture, disabled public replay hosting, local URL-fragment fallback behavior, replay caps, and negative raw-value exposure. * Focused web helper test passed. **Files Changed**: * `apps/web/tests/hostedPersistence.test.ts` - Added hosted persistence browser helper tests. **BQC Fixes**: * Contract alignment: Tests verify replay caps and disabled-state flags match the replay-link module and protocol summary. * Error information boundaries: Tests assert synthetic storage secrets, service-role keys, account ids, replay/export bodies, and local paths are absent. *** ### Task T012 - Add replay-link local-only regression assertions **Started**: 2026-05-30 10:15 **Completed**: 2026-05-30 10:16 **Duration**: 1 minute **Notes**: * Added replay-link regression coverage proving share URLs remain `#replay=` fragments, do not include public replay or upload paths, redact prompts/commands/paths/secrets/URLs, and reject oversized per-event payloads. * Focused replay-link test passed. **Files Changed**: * `apps/web/tests/replayLink.test.ts` - Added hosted persistence/public replay boundary regression assertions. **BQC Fixes**: * Contract alignment: Test asserts local replay fragment semantics stay aligned with Session 04 public replay boundary. * Error information boundaries: Test asserts raw prompt, secret, URL, and local path strings are absent after decoding. *** ### Task T013 - Update API docs for hosted persistence diagnostics **Started**: 2026-05-30 10:16 **Completed**: 2026-05-30 10:17 **Duration**: 1 minute **Notes**: * Documented `GET /diagnostics/hosted-persistence` as local planned-state diagnostics only, with storage/public replay activation exclusions and raw-value non-leakage rules. * Added the route to the REST endpoint table. **Files Changed**: * `docs/api/README_api.md` - Added hosted persistence diagnostics API documentation. *** ### Task T014 - Update hosted-service docs **Started**: 2026-05-30 10:17 **Completed**: 2026-05-30 10:17 **Duration**: 1 minute **Notes**: * Added Session 04 hosted persistence and public replay guardrails, data eligibility categories, storage activation requirements, public replay requirements, disabled-default posture, local-only fallback, and Phase 08 erasure handoff. **Files Changed**: * `docs/hosted-services.md` - Added hosted persistence and public replay boundary section. *** ### Task T015 - Update privacy docs **Started**: 2026-05-30 10:17 **Completed**: 2026-05-30 10:18 **Duration**: 1 minute **Notes**: * Added hosted persistence and public replay privacy guardrails covering blocked payload categories, local replay fragment limits, future retention/export/deletion/takedown requirements, Phase 08 erasure limits, and hosted persistence diagnostics no-raw-value rules. **Files Changed**: * `docs/privacy-and-security.md` - Added hosted persistence and public replay privacy section. *** ### Task T016 - Update architecture docs **Started**: 2026-05-30 10:18 **Completed**: 2026-05-30 10:18 **Duration**: 1 minute **Notes**: * Added protocol-first Session 04 architecture notes, hosted persistence planned/unavailable data-layer language, future server-mediated storage requirements, local URL-fragment replay boundary, and current gap updates. **Files Changed**: * `docs/ARCHITECTURE.md` - Added hosted persistence and public replay planned-state architecture. *** ### Task T017 - Update environment docs **Started**: 2026-05-30 10:18 **Completed**: 2026-05-30 10:19 **Duration**: 1 minute **Notes**: * Clarified hosted persistence and public replay as planned or disabled environment surfaces. * Documented that Supabase, storage, Cloudflare, public replay-shaped, and auth placeholders do not enable hosted persistence, public replay hosting, deletion, takedown, or erasure. **Files Changed**: * `docs/environments.md` - Added hosted persistence environment boundary. *** ### Task T018 - Update deployment docs **Started**: 2026-05-30 10:19 **Completed**: 2026-05-30 10:19 **Duration**: 1 minute **Notes**: * Clarified that Session 04 diagnostics and deployed Worker/public demo health are not hosted storage, public replay, retention, deletion, takedown, production validation, or erasure evidence. **Files Changed**: * `docs/deployment.md` - Added hosted persistence deployment boundary. *** ### Task T019 - Update release docs **Started**: 2026-05-30 10:19 **Completed**: 2026-05-30 10:20 **Duration**: 1 minute **Notes**: * Added Session 04 release guardrails, negative-claim checks, focused test expectations, docs review requirements, and Phase 08 validation/erasure deferrals. **Files Changed**: * `docs/release.md` - Added hosted persistence and public replay release checklist. *** ### Task T020 - Update protocol README **Started**: 2026-05-30 10:20 **Completed**: 2026-05-30 10:20 **Duration**: 1 minute **Notes**: * Documented protocol ownership of hosted persistence/public replay contracts and future consumer rules for storage, replay, deletion, takedown, and erasure labels. **Files Changed**: * `packages/protocol/README_protocol.md` -
