Session Start **Environment verified**: * [x] Prerequisites confirmed through `.spec_system/scripts/analyze-project.sh --json` * [x] Environment prerequisites confirmed through `.spec_system/scripts/check-prereqs.sh --json --env` * [x] Directory structure ready * [x] Workspace tools available through local npm workspace dependencies *** ### Task T001 - Verify prerequisites before editing source **Started**: 2026-05-30 09:26 **Completed**: 2026-05-30 09:27 **Duration**: 1 minute **Notes**: * Reviewed Phase 07 requirement routing matrix and confirmed Session 03 owns hosted identity lifecycle, authorization boundaries, role/audit requirements, and Worker authority non-overclaim. * Reviewed Session 01 and Session 02 prerequisite stubs plus the current hosted config source and diagnostics pattern. * Reviewed relevant ADRs for local-first workspace boundaries and optional Cloudflare Worker War Room relay. * Reviewed open finding `P06-S07-HOSTED-IDENTITY` in `.spec_system/SECURITY-COMPLIANCE.md`; it remains open until hosted account lifecycle, consent, authorization, revocation, audit, and end-to-end validation are defined without overclaiming Worker authority. **Files Changed**: * `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/implementation-notes.md` - Created session notes and recorded prerequisite evidence. *** ### Task T002 - Create implementation evidence notes shell **Started**: 2026-05-30 09:27 **Completed**: 2026-05-30 09:28 **Duration**: 1 minute **Notes**: * Created the required implementation notes shell for session progress, task evidence, command outcomes, skipped checks, and residual risks. * Recorded deterministic project analysis, environment prerequisites, and npm-workspace tool availability notes. **Files Changed**: * `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/implementation-notes.md` - Added progress table, environment evidence, and task log structure. *** ### Task T003 - Create hosted identity guardrail artifact **Started**: 2026-05-30 09:28 **Completed**: 2026-05-30 09:29 **Duration**: 1 minute **Notes**: * Added the Session 03 guardrail baseline covering lifecycle, consent, revocation, authorization, roles, audit, local-only fallback, diagnostics limits, abuse controls, non-overclaim labels, and Phase 08 handoffs. * Kept the artifact scoped to planned/unavailable requirements and negative claims; no hosted account runtime behavior was introduced. **Files Changed**: * `.spec_system/PRD/phase_07/hosted_identity_authorization_guardrails.md` - Created source-backed hosted identity and authorization guardrail baseline. *** ### Task T004 - Create hosted identity protocol contracts **Started**: 2026-05-30 09:29 **Completed**: 2026-05-30 09:31 **Duration**: 2 minutes **Notes**: * Added shared hosted identity status, lifecycle, authorization surface, role, audit, docs path, unsupported claim, and non-overclaim vocabulary. * Added pure summary/count builders with planned or unavailable status and local-only, not-shipped account runtime flags. **Files Changed**: * `packages/protocol/src/hostedIdentity.ts` - Created shared hosted identity guardrail contracts and helpers. **BQC Fixes**: * Contract alignment: Kept exported summary fields bounded to status labels, docs paths, booleans, and requirement arrays so server/web consumers do not invent divergent response shapes. *** ### Task T005 - Add hosted identity protocol tests **Started**: 2026-05-30 09:31 **Completed**: 2026-05-30 09:33 **Duration**: 2 minutes **Notes**: * Added protocol coverage for identity status vocabulary, lifecycle requirements, authorization surfaces, role/audit requirements, unsupported account claims, non-overclaim labels, unique exported values, and bounded summary counts. * Added negative assertions for raw account, OAuth, and Worker authority value leakage in generated summaries. **Files Changed**: * `packages/protocol/tests/hostedIdentity.test.ts` - Created protocol hosted identity contract tests. **BQC Fixes**: * Contract alignment: Tests verify exported arrays and summary counts stay synchronized for downstream diagnostics consumers. * Error information boundaries: Tests assert summaries do not contain raw account, OAuth, or Worker authority values. *** ### Task T006 - Create server hosted identity diagnostics builder **Started**: 2026-05-30 09:33 **Completed**: 2026-05-30 09:35 **Duration**: 2 minutes **Notes**: * Added a local diagnostics builder that delegates to the protocol summary and accepts only planned or unavailable status. * Kept the builder free of env parsing, raw account ids, token inputs, request bodies, authority token inputs, local paths, and file reads. **Files Changed**: * `apps/server/src/lib/hostedIdentity.ts` - Created status-only hosted identity diagnostics builder. **BQC Fixes**: * Error information boundaries: Builder accepts only a status enum and generated timestamp, preventing raw sensitive values from entering the diagnostics shape. * Contract alignment: Server summary uses the protocol contract directly. *** ### Task T007 - Wire hosted identity diagnostics route **Started**: 2026-05-30 09:35 **Completed**: 2026-05-30 09:37 **Duration**: 2 minutes **Notes**: * Added `GET /diagnostics/hosted-identity` to the existing diagnostics router. * Routed it through the same server middleware stack as existing diagnostics, including CORS, rate limiting, local bearer auth, and compact 503 error handling. * Added optional server dependency wiring for planned or unavailable hosted identity status. **Files Changed**: * `apps/server/src/routes/diagnostics.ts` - Added hosted identity diagnostics route. * `apps/server/src/server.ts` - Added optional hosted identity diagnostics status dependency. **BQC Fixes**: * Trust boundary enforcement: Route inherits existing local auth middleware before diagnostics are served. * Failure path completeness: Route catches builder failures and returns a bounded `diagnostics_unavailable` response. *** ### Task T008 - Add hosted identity diagnostics route tests **Started**: 2026-05-30 09:37 **Completed**: 2026-05-30 09:39 **Duration**: 2 minutes **Notes**: * Added route tests for default planned posture, unavailable posture, local bearer auth inheritance, local-only fallback, and synthetic secret redaction. * Confirmed tests assert no raw account, OAuth, authority, env, or local path values appear in diagnostics output. **Files Changed**: * `apps/server/tests/hostedIdentityDiagnostics.test.ts` - Created hosted identity diagnostics route coverage. **BQC Fixes**: * Trust boundary enforcement: Tests cover local bearer auth before diagnostics access. * Error information boundaries: Tests cover redaction and absence of raw sensitive values. *** ### Task T009 - Create browser hosted identity helper **Started**: 2026-05-30 09:39 **Completed**: 2026-05-30 09:41 **Duration**: 2 minutes **Notes**: * Added pure browser helper copy for planned and unavailable hosted identity posture. * Added explicit local-only fallback, no account UI, no OAuth redirect, no persisted account state, and War Room authority distinction fields. **Files Changed**: * `apps/web/src/lib/hostedIdentity.ts` - Created hosted identity browser posture and War Room authority boundary helpers. **BQC Fixes**: * State freshness on re-entry: Helper returns derived state only and persists no account identity state between lifecycles. * Accessibility and platform compliance: Copy helpers expose clear labels/titles for UI consumers without adding interactive account controls. *** ### Task T010 - Add hosted identity web helper tests **Started**: 2026-05-30 09:41 **Completed**: 2026-05-30 09:43 **Duration**: 2 minutes **Notes**: * Added browser helper tests for planned and unavailable hosted identity posture. * Added explicit checks that no account UI, OAuth redirect, or persisted account state is implied. * Added War Room authority boundary coverage for non-overclaim labels. **Files Changed**: * `apps/web/tests/hostedIdentity.test.ts` - Created hosted identity browser helper tests. **BQC Fixes**: * Contract alignment: Tests assert browser helper summaries align with protocol planned/unavailable states. * Error information boundaries: Tests assert no raw account, OAuth, Worker authority, or local path values appear in helper output. *** ### Task T011 - Export hosted identity contracts from protocol barrel **Started**: 2026-05-30 09:43 **Completed**: 2026-05-30 09:44 **Duration**: 1 minute **Notes**: * Exported the hosted identity contract module from the protocol package barrel for server and web consumers. **Files Changed**: * `packages/protocol/src/index.ts` - Added hosted identity barrel export. **BQC Fixes**: * Contract alignment: Downstream packages now import the same protocol-owned vocabulary through `@factionos/protocol`. *** ### Task T012 - Update API docs for hosted identity diagnostics **Started**: 2026-05-30 09:44 **Completed**: 2026-05-30 09:48 **Duration**: 4 minutes **Notes**: * Documented `GET /diagnostics/hosted-identity` as local planned-state diagnostics. * Added endpoint table coverage and reiterated that Worker authority is not hosted identity, SSO, organization membership, analytics consent, production audit proof, public collaboration safety, or trusted erasure. **Files Changed**: * `docs/api/README_api.md` - Added hosted identity diagnostics API documentation and negative-claim wording. *** ### Task T013 - Update hosted-service docs with identity guardrails **Started**: 2026-05-30 09:48 **Completed**: 2026-05-30 09:50 **Duration**: 2 minutes **Notes**: * Added a hosted identity boundary section with the Session 03 guardrail artifact, protocol module, diagnostics route, and web helper ownership. * Documented account lifecycle, consent, revocation, authorization, role/audit, and Worker authority non-overclaim requirements. **Files Changed**: * `docs/hosted-services.md` - Added hosted identity guardrails and expanded Supabase auth/persistence requirements. *** ### Task T014 - Update privacy docs with hosted identity privacy rules **Started**: 2026-05-30 09:50 **Completed**: 2026-05-30 09:52 **Duration**: 2 minutes **Notes**: * Added hosted identity privacy guardrails for account tokens, OAuth values, consent, revocation, audit, diagnostics, and Worker authority non-overclaim. * Updated open release risk wording so hosted auth and analytics require lifecycle, consent, revocation, audit, scrubbing, authorization, and local-only fallback before activation. **Files Changed**: * `docs/privacy-and-security.md` - Added hosted identity privacy guardrails and release-risk wording. *** ### Task T015 - Update architecture docs for hosted identity planned-state contracts **Started**: 2026-05-30 09:52 **Completed**: 2026-05-30 09:54 **Duration**: 2 minutes **Notes**: * Added Phase 07 Session 03 architecture notes for protocol-first hosted identity contracts and planned-state server/web consumers. * Preserved the separation between local server runtime, optional Worker room authority, and future account-backed hosted identity. **Files Changed**: * `docs/ARCHITECTURE.md` - Added hosted identity planned-state architecture and current-gap wording. *** ### Task T016 - Update environment docs for hosted identity variable boundaries **Started**: 2026-05-30 09:54 **Completed**: 2026-05-30 09:56 **Duration**: 2 minutes **Notes**: * Clarified that reserved Supabase, OAuth-shaped, Cloudflare, and local auth variables do not enable hosted identity or account-backed claims. * Added hosted identity environment boundary docs for planned/unavailable posture and future activation requirements. **Files Changed**: * `docs/environments.md` - Added hosted identity variable boundary and expanded future hosted auth/analytics privacy requirements. *** ### Task T017 - Update deployment docs for Worker and hosted identity proof limits **Started**: 2026-05-30 09:56 **Completed**: 2026-05-30 09:57 **Duration**: 1 minute **Notes**: * Clarified that Session 03 adds planned-state hosted identity diagnostics only. * Documented that Worker deploy success, Worker health, Cloudflare domain state, and browser Worker URLs are not hosted identity proof. **Files Changed**: * `docs/deployment.md` - Added hosted identity deployment boundary and Worker non-proof wording. *** ### Task T018 - Update release docs with hosted identity release guardrails **Started**: 2026-05-30 09:57 **Completed**: 2026-05-30 09:59 **Duration**: 2 minutes **Notes**: * Added Session 03 hosted identity guardrail checks for protocol, server, web, and docs. * Kept negative claims explicit and preserved Phase 08 ownership of production-hosted validation, trusted erasure, certification, release hardening, and decommission. **Files Changed**: * `docs/release.md` - Added hosted identity release guardrails and Phase 08 deferral wording. *** ### Task T019 - Update protocol README for hosted identity ownership **Started**: 2026-05-30 09:59 **Completed**: 2026-05-30 10:00 **Duration**: 1 minute **Notes**: * Documented `src/hostedIdentity.ts` as the protocol-owned source for hosted identity status, lifecycle, authorization, role, audit, docs, unsupported claim, and non-overclaim vocabulary. * Added future consumer rules so server/web/Worker/CLI/hooks/adapters do not redefine hosted identity labels. **Files Changed**: * `packages/protocol/README_protocol.md` - Added hosted identity contract ownership guidance. *** ### Task T020 - Update server README for hosted identity diagnostics **Started**: 2026-05-30 10:00 **Completed**: 2026-05-30 10:02 **Duration**: 2 minutes **Notes**: * Added hosted identity diagnostics to the server route table and diagnostics section. * Documented planned/unavailable state, local auth inheritance, redaction boundaries, and no account-runtime claims. **Files Changed**: * `apps/server/README_server.md` -
