The session makes the current posture explicit and source-backed: browser notifications remain local OS notifications, Web Push and VAPID remain reserved, remote access and Cloudflare tunnels remain unavailable until a later explicit opt-in, and hosted-service diagnostics report only bounded posture (labels, counts, docs paths, booleans) without exposing raw secrets, ids, tokens, paths, payloads, logs, backups, exports, or replay buffers. This closed the last source-backed guardrail gap before the Phase 07 validation closeout (routing requirements P07-R017 through P07-R019). *** ## Deliverables ### Files Created | File | Purpose | Lines | | --------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- | ----- | | `.spec_system/PRD/phase_07/push_remote_access_operator_diagnostics_guardrails.md` | Source-backed push/VAPID/remote/tunnel/diagnostics guardrail baseline | \~263 | | `packages/protocol/src/hostedOperations.ts` | Shared hosted operation status, surface, requirement, blocked payload, claim, and summary contracts | \~328 | | `packages/protocol/tests/hostedOperations.test.ts` | Protocol contract coverage and negative-claim/leak assertions | \~186 | | `apps/server/src/lib/hostedOperations.ts` | Local hosted operation diagnostics snapshot builder | \~30 | | `apps/server/tests/hostedOperationsDiagnostics.test.ts` | Server route tests for auth, CORS, posture, unsupported methods, leak prevention | \~190 | | `apps/web/src/lib/hostedOperations.ts` | Browser hosted operation posture helper | \~255 | | `apps/web/tests/hostedOperations.test.ts` | Browser helper coverage for local/unavailable posture | \~145 | ### Files Modified | File | Changes | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------- | | `packages/protocol/src/index.ts` | Exported hosted operation contracts from the barrel | | `packages/protocol/src/hostedConfig.ts` | Refined reserved VAPID and Cloudflare/tunnel metadata; browser-blocked mirrors | | `packages/protocol/tests/hostedConfig.test.ts` | Regression coverage for reserved/secret/browser-blocked VAPID and Cloudflare/tunnel values | | `apps/server/src/routes/diagnostics.ts` | Wired `GET /diagnostics/hosted-operations` through existing auth/CORS/rate-limit stack | | `apps/server/src/server.ts` | Optional hosted operation diagnostics status passthrough | | `apps/cli/src/lib/orchestrationDiagnostics.js` | Loopback-only fetch, compaction, redaction, and description helpers | | `apps/cli/src/commands/status.js` | Compact hosted operation posture output | | `apps/cli/src/commands/doctor.js` | Route availability and inactive-surface checks | | `apps/cli/tests/orchestrationDiagnostics.test.js` | Helper coverage for compaction, non-loopback rejection, sanitization | | `apps/cli/tests/cliRuntime.test.js` | Runtime fixture and status/doctor output assertions | | `apps/web/src/lib/notifications.ts` | Local notification copy and bounded payload/click-target sanitization | | `apps/web/public/sw.js` | Bounded future push payload parsing and same-origin click-target sanitization | | `apps/web/tests/notifications.test.ts` | Local-only copy and bounded push-adjacent payload regression coverage | | `.env.local.example` | Aligned VAPID and Cloudflare/tunnel comments with no-raw-value posture | | `docs/api/README_api.md`, `docs/hosted-services.md`, `docs/privacy-and-security.md`, `docs/ARCHITECTURE.md`, `docs/environments.md`, `docs/deployment.md`, `docs/release.md` | Documented diagnostics route, guardrails, blocked categories, and Phase 08 deferrals | | `packages/protocol/README_protocol.md`, `apps/server/README_server.md`, `apps/cli/README_cli.md`, `apps/web/README_web.md` | Package README alignment for contract ownership, route behavior, loopback probes, and notification posture | *** ## Technical Decisions 1. **Protocol-first vocabulary**: One protocol-owned summary shape feeds server, CLI, and web consumers so posture labels and counts stay consistent and bounded across surfaces. 2. **Planned-state scaffolding**: Source reports `planned`/`disabled`/ `unavailable` posture without creating any push subscription, VAPID consumption, remote access, or tunnel activation path. 3. **Loopback-only CLI diagnostics**: `fetchHostedOperationDiagnostics` fails closed on non-loopback URLs before any network request, and all failure text passes through `sanitizeDiagnosticText` (Bearer tokens, key=value secrets, URLs, and filesystem paths redacted). 4. **Boundary-local redaction**: The server route returns only labels, counts, docs paths, and booleans with no request-body echo; the service worker bounds push payload fields and constrains click targets to same-origin relative URLs. *** ## Test Results | Metric | Value | | ---------- | -------------------------------- | | Test Files | 7 | | Tests | 64 | | Passed | 64 | | Failed | 0 | | Typechecks | protocol, server, web - all pass | *** ## Lessons Learned 1. Static public assets like `apps/web/public/sw.js` need a lightweight repo-root file read in the web test environment, since `import.meta.url` is not a file URL there. 2. Asserting posture labels rather than full command output keeps CLI status and doctor tests stable against formatting drift. *** ## Future Considerations Items for future sessions: 1. Phase 08 owns any actual push delivery, VAPID consumption, remote access, and Cloudflare tunnel activation, each gated on consent, authorization, revocation, redaction, rate-limit, and abuse-control scope. 2. Phase 08 owns trusted unified erasure; current unsubscribe, local reset, diagnostics cleanup, Worker leave, and tunnel revocation are not trusted erasure. 3. Session 07 will run the Phase 07 validation and documentation closeout. *** ## Session Statistics * **Tasks**: 25 completed * **Files Created**: 7 * **Files Modified**: 25 * **Tests Added**: hosted operation coverage across protocol, server, CLI, web (64 focused tests passing) * **Blockers**: 0 resolved --- # 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-session06-push-remote-access-and-operator-diagnostics-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.
