The work established shared planned-state identity vocabulary, a redacted local diagnostics route, browser copy helpers, and stable doc updates that keep room-local Worker authority from being described as hosted account identity, SSO, organization membership, or production audit proof. The session stayed local-first. The cockpit continues to work without hosted accounts, OAuth, Supabase, hosted storage, analytics, public replay hosting, push, or remote access. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | ----- | | `.spec_system/PRD/phase_07/hosted_identity_authorization_guardrails.md` | Source-backed hosted identity and authorization guardrail baseline | \~240 | | `packages/protocol/src/hostedIdentity.ts` | Shared hosted identity posture contracts, requirement vocabulary, docs paths, diagnostics shapes, and pure helpers | \~240 | | `packages/protocol/tests/hostedIdentity.test.ts` | Protocol tests for lifecycle requirements, authorization surfaces, non-overclaim vocabulary, and bounded summary shapes | \~170 | | `apps/server/src/lib/hostedIdentity.ts` | Local hosted identity diagnostics builder with redacted planned-state output | \~150 | | `apps/server/tests/hostedIdentityDiagnostics.test.ts` | Server route tests for auth inheritance, planned status, local-only fallback, and no raw token leakage | \~150 | | `apps/web/src/lib/hostedIdentity.ts` | Browser helper for hosted identity unavailable/planned state and Worker authority distinction | \~130 | | `apps/web/tests/hostedIdentity.test.ts` | Web helper tests for local-only fallback, planned copy, and War Room authority non-overclaim | \~130 | | `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/implementation-notes.md` | Task log and command evidence | \~220 | | `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/security-compliance.md` | Security and GDPR review | \~120 | | `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/validation.md` | PASS validation report | \~200 | | `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~120 | ### Files Modified | File | Changes | | ------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------- | | `.spec_system/specs/phase07-session03-hosted-identity-and-authorization-guardrails/spec.md` | Marked the session complete | | `.spec_system/PRD/phase_07/PRD_phase_07.md` | Updated the phase progress tracker, completed sessions, and Session 03 outputs | | `.spec_system/PRD/PRD.md` | Updated the Phase 07 product status map and carried forward the completed Session 03 baseline | | `.spec_system/state.json` | Cleared the active session and recorded Session 03 completion history | | `package.json` | Bumped the root patch version from `0.1.65` to `0.1.66` | | `packages/protocol/src/index.ts` | Exported hosted identity contracts from the protocol barrel | | `apps/server/src/routes/diagnostics.ts` | Added `GET /diagnostics/hosted-identity` to the diagnostics router | | `apps/server/src/server.ts` | Added the optional hosted identity diagnostics dependency seam | | `docs/api/README_api.md` | Documented the local hosted identity diagnostics endpoint and negative claims | | `docs/hosted-services.md` | Added hosted identity guardrails and non-overclaim wording | | `docs/privacy-and-security.md` | Added account-token, authority-token, consent, revocation, audit, and redaction rules | | `docs/ARCHITECTURE.md` | Documented protocol-first hosted identity guardrails and local/Worker separation | | `docs/environments.md` | Clarified that reserved hosted-auth variables do not imply active hosted identity | | `docs/deployment.md` | Clarified deployment and Worker URLs are not hosted identity proof | | `docs/release.md` | Added hosted identity release guardrails and Phase 08 deferrals | | `packages/protocol/README_protocol.md` | Documented protocol ownership of hosted identity contracts | | `apps/server/README_server.md` | Documented server hosted identity diagnostics and redaction boundaries | | `apps/web/README_web.md` | Documented browser planned-state helpers and no account UI | | `apps/warroom/README_warroom.md` | Reaffirmed room-local authority is not hosted account identity | *** ## Technical Decisions 1. **Protocol-first contract ownership**: Shared hosted identity vocabulary lives in `packages/protocol` so server and web consumers cannot drift on the meaning of planned or unavailable states. 2. **Redacted diagnostics only**: The server route reports posture labels, docs paths, and requirement counts without emitting raw account, OAuth, or authority values. *** ## Test Results | Metric | Value | | -------- | ------------ | | Tests | 2127 total | | Passed | 2126 | | Coverage | Not reported | Focused hosted identity checks passed for protocol, server, and web helpers: * `npm test -- packages/protocol/tests/hostedIdentity.test.ts apps/server/tests/hostedIdentityDiagnostics.test.ts apps/web/tests/hostedIdentity.test.ts` * Result: 14 passed, 0 failed *** ## Lessons Learned 1. Planned-state identity wording needs to live beside the runtime contracts so the docs, tests, and diagnostics stay aligned. 2. Negative-claim tests are the most reliable guardrail for keeping Worker authority from being mistaken for hosted account identity. *** ## Future Considerations Items for future sessions: 1. Define hosted persistence and public replay guardrails without broadening the identity surface. 2. Keep release-phase validation, trusted erasure, and production-hosted checks in later Phase 07 and Phase 08 work. *** ## Session Statistics * **Tasks**: 25 completed * **Files Created**: 11 * **Files Modified**: 18 * **Tests Added**: 3 * **Blockers**: 0 --- # Agent Instructions This documentation is published with GitBook.

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/phase07-session03-hosted-identity-and-authorization-guardrails/implementation_summary.md?ask=&goal= ``` `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.
