## Docs Review

* Stable docs and package READMEs describe hosted config diagnostics as local and status-only.
* Browser docs describe public-client config as publishable and optional, not secret-safe.
* Docs keep hosted auth, hosted storage, analytics capture, push delivery, public replay hosting, remote access, hosted diagnostics upload, production-hosted validation, trusted erasure, certification, release hardening, and decommission completion deferred.

## Residual Risks

* Production-hosted validation, hosted identity, hosted persistence, analytics consent, push, remote access, hosted diagnostics upload, public replay hosting, and trusted unified erasure remain deferred to later Phase 07 sessions or Phase 08.
* The current diagnostics route reports local process/env posture only; it does not probe external hosted accounts or deployment health.
* `.spec_system/state.json` was already modified before implementation began and was preserved as existing session setup.

## Handoff

Ready for the `validate` workflow step.

* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded README details.

**BQC Fixes**:

* Contract alignment: package docs now point to the owning source module and matching route/helper behavior.
* Error information boundaries: README docs call out blocked deploy-only/browser exposure paths.

***

### Task T017 - Update hosted config docs

**Started**: 2026-05-30 09:06 **Completed**: 2026-05-30 09:09 **Duration**: 3 minutes

**Notes**:

* Updated stable docs for source-backed hosted config categories, status-only diagnostics, local-only fallback, browser-visible config limits, deploy-only separation, release checks, and API route shape.
* Confirmed wording keeps hosted auth, hosted storage, analytics, push, public replay, remote access, hosted diagnostics upload, production validation, and trusted erasure out of shipped claims.

**Files Changed**:

* `docs/environments.md` - added hosted config diagnostics section and source ownership.
* `docs/hosted-services.md` - added Session 02 hosted configuration boundary.
* `docs/privacy-and-security.md` - added diagnostics privacy guarantees.
* `docs/deployment.md` - clarified hosted config diagnostics and deploy-only boundary.
* `docs/release.md` - added Phase 07 Session 02 release checks.
* `docs/api/README_api.md` - documented `/diagnostics/hosted-config` and local route status.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded docs details.

**BQC Fixes**:

* Error information boundaries: docs define status-only diagnostics and raw-value exclusions.
* Contract alignment: docs now name the protocol, server, and web source files that own the behavior.

***

### Task T016 - Update root and server env examples

**Started**: 2026-05-30 09:04 **Completed**: 2026-05-30 09:06 **Duration**: 2 minutes

**Notes**:

* Updated root and server env examples with source-backed hosted config diagnostics comments, public-client limits, blocked `VITE_` mirror guidance, server-only secret examples, deploy-only Cloudflare separation, and reserved future hosted values.
* Removed nonblank provider and Cloudflare placeholder values from `.env.local.example` so copying the example does not make diagnostics report placeholder credentials as present.

**Files Changed**:

* `.env.local.example` - clarified diagnostics, public-client, blocked mirror, server-only, and deploy-only comments.
* `apps/server/.env.example` - added hosted config diagnostics and boundary comments.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded env example details.

**BQC Fixes**:

* Error information boundaries: examples now state diagnostics are status-only and raw values are excluded.
* Trust boundary enforcement: examples explicitly block `VITE_` mirrors of server-only and deploy-only values.

***

### Task T015 - Create web hosted config helper tests

**Started**: 2026-05-30 09:04 **Completed**: 2026-05-30 09:04 **Duration**: 1 minute

**Notes**:

* Added browser helper tests for valid Worker URLs, blank/absent local-only fallback, malformed URL schemes, URL credentials, query strings, reserved Supabase placeholders, known blocked mirrors, unknown secret-like `VITE_` values, and raw-value exclusion.
* Focused command passed: `npx vitest run apps/web/tests/hostedConfig.test.ts apps/web/tests/warRoomDiagnostics.test.ts`.

**Files Changed**:

* `apps/web/tests/hostedConfig.test.ts` - new browser config helper tests.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded test details.

**BQC Fixes**:

* Contract alignment: tests lock helper behavior against protocol-backed statuses.
* Error information boundaries: tests assert blocked browser values are not serialized.

***

### Task T014 - Integrate browser helper with War Room defaults

**Started**: 2026-05-30 09:03 **Completed**: 2026-05-30 09:04 **Duration**: 1 minute

**Notes**:

* Routed `readBrowserSafeDefaultWarRoomWorkerUrl` through the hosted browser config helper.
* Existing War Room source classification remains covered by focused diagnostics tests for disabled, invalid, local Wrangler, workers.dev, and custom domain states.

**Files Changed**:

* `apps/web/src/lib/warRoomDiagnostics.ts` - uses hosted config helper for default Worker URL reading.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded integration details.

**BQC Fixes**:

* Contract alignment: War Room default URL parsing now consumes protocol-backed browser config status.
* State freshness on re-entry: helper reads caller-provided env records rather than caching browser config.

***

### Task T008 - Create browser hosted config helper

**Started**: 2026-05-30 09:02 **Completed**: 2026-05-30 09:03 **Duration**: 1 minute

**Notes**:

* Added browser hosted config helpers that read explicit Vite env records, validate documented browser-visible variables, normalize only safe public URLs, keep local-only fallback for absent/blank/malformed/reserved config, and flag known or unknown secret-like `VITE_` values as blocked.
* Helper output is status-only except for normalized safe public Worker URLs.

**Files Changed**:

* `apps/web/src/lib/hostedConfig.ts` - new browser hosted config helper.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded implementation details.

**BQC Fixes**:

* Trust boundary enforcement: browser env records are schema-filtered to `VITE_` names and string or undefined values.
* Failure path completeness: unsafe, malformed, reserved, absent, and blank config all return bounded local-only statuses.

***

### Task T013 - Create hosted config diagnostics route tests

**Started**: 2026-05-30 09:01 **Completed**: 2026-05-30 09:02 **Duration**: 1 minute

**Notes**:

* Added route tests for empty-env local fallback, bearer auth inheritance, blocked browser mirror reporting, bounded shape, and synthetic secret redaction.
* Focused command passed: `npx vitest run apps/server/tests/hostedConfigDiagnostics.test.ts`.

**Files Changed**:

* `apps/server/tests/hostedConfigDiagnostics.test.ts` - new hosted config diagnostics route tests.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded route test details.

**BQC Fixes**:

* Trust boundary enforcement: tests prove diagnostics require the existing bearer token when local auth is enabled.
* Error information boundaries: tests assert synthetic raw secrets, account ids, zone ids, local paths, and webhook suffixes are excluded.

***

### Task T012 - Wire hosted config diagnostics dependencies

**Started**: 2026-05-30 09:01 **Completed**: 2026-05-30 09:01 **Duration**: 1 minute

**Notes**:

* Added an optional `hostedConfigEnv` server creation seam for tests and diagnostics.
* Default runtime still reads process env only inside diagnostics; no hosted variable is required for startup.

**Files Changed**:

* `apps/server/src/server.ts` - passed optional hosted config env into diagnostics dependencies.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded wiring details.

**BQC Fixes**:

* State freshness on re-entry: tests can inject explicit env records, avoiding stale process env coupling.
* Failure path completeness: absent hosted config remains local-only rather than a startup failure.

### Task T011 - Add hosted config diagnostics route

**Started**: 2026-05-30 09:00 **Completed**: 2026-05-30 09:01 **Duration**: 1 minute

**Notes**:

* Added `GET /diagnostics/hosted-config` to the existing diagnostics router.
* The route is mounted behind the server's existing CORS, rate limit, JSON, and local bearer auth middleware.
* Route errors map to a bounded `diagnostics_unavailable` response without exposing exception details.

**Files Changed**:

* `apps/server/src/routes/diagnostics.ts` - added hosted config diagnostics route.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded route details.

**BQC Fixes**:

* Trust boundary enforcement: route inherits boundary-nearest local auth middleware.
* Failure path completeness: route catch path emits a stable safe error envelope.

### Task T010 - Implement redacted server posture details and counts

**Started**: 2026-05-30 08:58 **Completed**: 2026-05-30 09:00 **Duration**: 2 minutes

**Notes**:

* Server hosted config diagnostics now include deterministic protocol metadata order, sorted unknown blocked browser mirrors, status-only variable entries, category/exposure/status counts, docs paths, and local-only posture.
* Unknown secret-like `VITE_` values are represented as blocked entries without raw values.

**Files Changed**:

* `apps/server/src/lib/hostedConfig.ts` - added aggregate posture details and deterministic blocked mirror handling.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded implementation details.

**BQC Fixes**:

* Error information boundaries: posture entries expose compact labels only.
* Contract alignment: counts use protocol-owned category, exposure, and status vocabularies.

***

### Task T009 - Export protocol hosted config contracts

**Started**: 2026-05-30 08:58 **Completed**: 2026-05-30 08:59 **Duration**: 1 minute

**Notes**:

* Exported the hosted config contract from the protocol package barrel so server and web imports use `@factionos/protocol`.

**Files Changed**:

* `packages/protocol/src/index.ts` - added `export * from "./hostedConfig.js";`.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded export details.

**BQC Fixes**:

* Contract alignment: server consumers now use the shared protocol barrel instead of a package-internal path.

***

### Task T007 - Create server hosted config unit tests

**Started**: 2026-05-30 08:59 **Completed**: 2026-05-30 09:00 **Duration**: 1 minute

**Notes**:

* Added server unit tests for empty-env local-only fallback, blank values, valid public Worker URL, reserved Supabase placeholders, deploy-only Cloudflare credentials, server-only secrets, blocked `VITE_` mirrors, unknown secret-like browser names, and redaction.
* Initial focused run exposed the missing protocol barrel export; fixed by exporting `hostedConfig` from `packages/protocol/src/index.ts`.
* Focused command passed after the fix: `npx vitest run apps/server/tests/hostedConfig.test.ts`.

**Files Changed**:

* `apps/server/tests/hostedConfig.test.ts` - new server helper tests.
* `packages/protocol/src/index.ts` - exported hosted config contracts for package consumers.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded test details.

**BQC Fixes**:

* Contract alignment: tests caught the missing protocol barrel export before route/web integration.
* Error information boundaries: tests assert synthetic secrets, account ids, paths, and raw URLs never appear in serialized diagnostics.

***

### Task T006 - Create server hosted config posture builder

**Started**: 2026-05-30 08:58 **Completed**: 2026-05-30 08:59 **Duration**: 1 minute

**Notes**:

* Added a server helper that accepts explicit env records, validates env key/value shape, emits protocol diagnostic entries, detects unknown secret-like `VITE_` mirrors, and returns count summaries with local-only posture.
* The helper never returns raw env values.

**Files Changed**:

* `apps/server/src/lib/hostedConfig.ts` - new server hosted config diagnostics builder.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded implementation details.

**BQC Fixes**:

* Trust boundary enforcement: env input is normalized to uppercase env-name keys and string or undefined values only.
* Error information boundaries: diagnostics include names, categories, statuses, docs, and counts only; raw values are never serialized.

***

### Task T005 - Create protocol hosted config contract tests

**Started**: 2026-05-30 08:57 **Completed**: 2026-05-30 08:58 **Duration**: 1 minute

**Notes**:

* Added Vitest coverage for category, exposure, and status vocabularies; metadata uniqueness; representative variable classifications; blocked browser mirrors; safe public URL normalization; and status-only summary shapes.
* Focused command passed: `npx vitest run packages/protocol/tests/hostedConfig.test.ts`.

**Files Changed**:

* `packages/protocol/tests/hostedConfig.test.ts` - new protocol contract tests.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded test details.

**BQC Fixes**:

* Contract alignment: tests lock representative metadata and diagnostic shapes.
* Error information boundaries: tests assert summaries do not include synthetic raw secret values.

***

### Task T004 - Create protocol hosted config contracts

**Started**: 2026-05-30 08:54 **Completed**: 2026-05-30 08:57 **Duration**: 3 minutes

**Notes**:

* Added protocol-owned hosted config categories, exposure values, status values, docs paths, variable metadata, browser exposure helpers, public URL normalization, variable diagnostics, and count helpers.
* Kept all helpers deterministic and side-effect free.

**Files Changed**:

* `packages/protocol/src/hostedConfig.ts` - new shared hosted config contract module.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded implementation details.

**BQC Fixes**:

* Trust boundary enforcement: blocked browser mirror helpers reject known and secret-like `VITE_` names without inspecting or returning raw values.
* Failure path completeness: public URL normalization returns bounded status and reason codes instead of throwing or echoing input.

***

### Task T003 - Confirm current-session cleanup state

**Started**: 2026-05-30 08:53 **Completed**: 2026-05-30 08:54 **Duration**: 1 minute

**Notes**:

* Current session directory initially contained only `spec.md` and `tasks.md`; `implementation-notes.md` was created for this run.
* Phase 07 specs include Session 01 and current Session 02 only. No stale duplicate current-session files or older-than-retention active specs required cleanup.
* Existing user/generated spec-system changes were preserved.

**Files Changed**:

* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded cleanup review.

**BQC Fixes**:

* N/A - context verification only.

***

### Task T002 - Review env examples and diagnostics source boundaries

**Started**: 2026-05-30 08:52 **Completed**: 2026-05-30 08:53 **Duration**: 1 minute

**Notes**:

* Reviewed `.env.local.example`, `apps/server/.env.example`, existing isolation diagnostics, diagnostics route wiring, server auth middleware placement, and War Room browser URL helpers.
* Confirmed existing diagnostics routes inherit global local bearer auth because the diagnostics router is mounted after `createLocalAuthMiddleware`.
* Confirmed existing War Room URL behavior normalizes only valid http(s) Worker URLs and falls back to empty local-only mode for invalid values.

**Files Changed**:

* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded source-boundary review.

**BQC Fixes**:

* N/A - context verification only.

***

### Task T001 - Verify Session 01 artifacts and source inventory

**Started**: 2026-05-30 08:51 **Completed**: 2026-05-30 08:52 **Duration**: 1 minute

**Notes**:

* Analyzer resolved the current session, Phase 07 state, completed Session 01, and cross-package scope.
* Reviewed Session 01 hosted services baseline, routing matrix, and hosted payload privacy blocklist.
* Confirmed Session 02 owns hosted configuration categories, disabled defaults, public-client/server-only/deploy-only boundaries, diagnostics, and local fallback.

**Files Changed**:

* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/tasks.md` - marked task complete and updated progress.
* `.spec_system/specs/phase07-session02-hosted-configuration-and-client-exposure-boundaries/implementation-notes.md` - recorded setup evidence.

**BQC Fixes**:

* N/A - context verification only.

***

### 2026-05-30 - Session Start

**Environment verified**:

* [x] Prerequisites confirmed with `.spec_system/scripts/check-prereqs.sh --json --env`
* [x] Session resolved by analyzer as `phase07-session02-hosted-configuration-and-client-exposure-boundaries`
* [x] Directory structure ready
* [x] Workspace-local tools available through `node_modules/.bin` and npm scripts

**Notes**:

* Optional global tool probe reported `tsc`, `vitest`, and `biome` missing from global PATH, but the repository has local binaries in `node_modules/.bin`; verification will use npm scripts or local binaries.
