Verify prior War Room validation and boundaries **Started**: 2026-05-30 01:52 **Completed**: 2026-05-30 01:53 **Duration**: 1 minute **Notes**: * Reviewed Session 05 validation and security reports; validation passed with 22/22 tasks complete, root tests passing, ASCII/LF confirmed, and no security or GDPR findings. * Confirmed the inherited boundary: federation uses allowlisted redacted frames, sender exclusion, bounded catch-up, and no DB-layer changes. **Files Changed**: * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T001 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded setup verification evidence. ### Task T002 - Review current web and Worker docs **Started**: 2026-05-30 01:53 **Completed**: 2026-05-30 01:54 **Duration**: 1 minute **Notes**: * Reviewed deployment, environment, package README, workflow, API, architecture, privacy, release, and incident-response docs. * Identified stale Session 01-era wording that still describes the web War Room panel as a stub or not fully wired; later documentation tasks will replace this with optional redacted Worker federation and diagnostic behavior. * Confirmed Cloudflare credentials remain documented as operational/deploy-only inputs, not local core runtime requirements. **Files Changed**: * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T002 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded stale-doc review evidence. ### Task T003 - Confirm database and hosted-service scope **Started**: 2026-05-30 01:54 **Completed**: 2026-05-30 01:55 **Duration**: 1 minute **Notes**: * Confirmed `CONVENTIONS.md` reports no configured database layer and the session spec explicitly excludes database/schema migration work. * Searched for database migration tooling and found no Prisma/Drizzle/SQL database scope; the existing `apps/warroom/wrangler.toml` migration is a Cloudflare Durable Object class registration. * Confirmed this session remains optional Worker diagnostics only: no hosted auth, hosted storage, analytics, public replay hosting, or required Cloudflare credentials for core local use. **Files Changed**: * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T003 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded scope confirmation. ### Task T004 - Create War Room diagnostic helper **Started**: 2026-05-30 01:55 **Completed**: 2026-05-30 02:01 **Duration**: 6 minutes **Notes**: * Added a pure diagnostic helper for Worker URL source labels, browser-safe default URL loading, local-only disabled state, invalid URL state, loading, unchecked, healthy, connected, offline, timeout, rate-limited, bad-response, and generic error diagnostics. * Kept user-facing diagnostic copy bounded and avoided echoing full Worker URLs, account ids, paths, tokens, response bodies, or raw failure payloads. **Files Changed**: * `apps/web/src/lib/warRoomDiagnostics.ts` - created source classification, health diagnostic derivation, and rate-limit copy helpers. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T004 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded helper implementation. **BQC Fixes**: * Error information boundaries: diagnostic copy intentionally uses labels and safe failure messages rather than raw Worker URLs or response content (`apps/web/src/lib/warRoomDiagnostics.ts`). ### Task T005 - Add diagnostic helper tests **Started**: 2026-05-30 02:01 **Completed**: 2026-05-30 02:02 **Duration**: 1 minute **Notes**: * Added focused Vitest coverage for browser-safe default Worker URL loading, disabled/local Wrangler/workers.dev/custom/invalid URL classification, health-state copy, rate-limit copy, stale diagnostic reset, and sensitive URL fragment absence. * Ran `npx vitest run apps/web/tests/warRoomDiagnostics.test.ts`; 6 tests passed. **Files Changed**: * `apps/web/tests/warRoomDiagnostics.test.ts` - created diagnostics helper coverage. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T005 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded test evidence. **BQC Fixes**: * Contract alignment: tests pin helper output for disabled, invalid, loading, success, connected, timeout, offline, rate-limited, bad-response, and generic error states (`apps/web/tests/warRoomDiagnostics.test.ts`). ### Task T006 - Extend War Room client health parsing **Started**: 2026-05-30 02:02 **Completed**: 2026-05-30 02:05 **Duration**: 3 minutes **Notes**: * Enriched the health response contract with compact rate-limit and deployment metadata. * Sanitized health parsing so extra Worker response fields are not returned to the caller. * Extended HTTP failure mapping to treat 429 responses as rate-limited and read bounded retry metadata from either JSON envelopes or `Retry-After` headers. * Ran `npx vitest run apps/web/tests/warRoomClient.test.ts apps/web/tests/warRoomDiagnostics.test.ts`; 15 tests passed. **Files Changed**: * `apps/web/src/lib/warRoomClient.ts` - added enriched health types, sanitized health parser, and retry-after failure mapping. * `apps/web/tests/warRoomClient.test.ts` - updated existing health success fixture for the enriched response contract. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T006 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded client parsing evidence. **BQC Fixes**: * Error information boundaries: health parsing returns only compact typed service/time/rate-limit/deployment fields and drops unknown response fields (`apps/web/src/lib/warRoomClient.ts`). * External dependency resilience: health checks continue to use the existing bounded timeout and map offline, timeout, rate-limit, malformed, and HTTP failures to caller-visible states (`apps/web/src/lib/warRoomClient.ts`). ### Task T007 - Add compact Worker health metadata **Started**: 2026-05-30 02:05 **Completed**: 2026-05-30 02:08 **Duration**: 3 minutes **Notes**: * Updated `/health` to return service, ISO time, app-level rate-limit enabled/max/window metadata, and deployment-safe labels. * Deployment metadata is derived from the request host as `local-wrangler`, `workers-dev`, `custom-domain`, or `unknown`; it does not echo account ids, tokens, paths, request headers, or request bodies. * Ran `npx vitest run apps/warroom/tests/worker.test.ts`; 12 tests passed. **Files Changed**: * `apps/warroom/src/index.ts` - added compact health response metadata and safe deployment classification. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T007 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded Worker health metadata implementation. **BQC Fixes**: * Error information boundaries: Worker health metadata uses deployment type labels instead of hostnames, account ids, request headers, or request body details (`apps/warroom/src/index.ts`). ### Task T008 - Add Worker health metadata tests **Started**: 2026-05-30 02:08 **Completed**: 2026-05-30 02:10 **Duration**: 2 minutes **Notes**: * Added Worker health tests for compact metadata, custom-domain/local-wrangler/workers.dev labels, configured rate-limit values, disabled app-level rate limiting, and sensitive request-detail absence. * Ran `npx vitest run apps/warroom/tests/warroom.test.ts apps/warroom/tests/worker.test.ts`; 38 tests passed. **Files Changed**: * `apps/warroom/tests/warroom.test.ts` - added Worker health metadata and privacy tests. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T008 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded Worker health test evidence. **BQC Fixes**: * Contract alignment: tests require compact health metadata and prohibit host, token, secret, IP, header, request, and URL echo in health responses (`apps/warroom/tests/warroom.test.ts`). ### Task T009 - Load browser-safe default Worker URL before storage overrides **Started**: 2026-05-30 02:10 **Completed**: 2026-05-30 02:13 **Duration**: 3 minutes **Notes**: * Added default Worker URL loading through the diagnostics helper so `VITE_FACTIONOS_WARROOM_WORKER_URL` can provide a browser-safe default when no localStorage hint exists. * Preserved localStorage override semantics: a stored empty Worker URL keeps local-only mode even when a default URL exists. * Ran `npx vitest run apps/web/tests/warRoomIdentity.test.ts apps/web/tests/warRoomDiagnostics.test.ts`; 13 tests passed. **Files Changed**: * `apps/web/src/lib/warRoomIdentity.ts` - loaded browser-safe default Worker URL in fallback identity hints. * `apps/web/tests/warRoomIdentity.test.ts` - covered default loading and stored empty override behavior. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T009 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded identity default implementation. **BQC Fixes**: * State freshness on re-entry: hydration still rebuilds identity from storage/defaults and closes any existing room context before re-entering (`apps/web/src/lib/warRoomIdentity.ts`, `apps/web/src/store/useWarRoomStore.ts`). ### Task T010 - Add store-owned Worker health diagnostics **Started**: 2026-05-30 02:13 **Completed**: 2026-05-30 02:18 **Duration**: 5 minutes **Notes**: * Added `healthDiagnostic` state and a `checkWorkerHealth` action to the War Room store. * Guarded duplicate health checks while in flight and dropped stale health responses when the Worker URL input changed before the response returned. * Reset diagnostic state on Worker URL edits, hint saves, storage hydration, local room reset, disconnect, leave, and socket close cleanup. * Ran `npx vitest run apps/web/tests/warRoomStore.test.ts apps/web/tests/warRoomIdentity.test.ts apps/web/tests/warRoomDiagnostics.test.ts`; 27 tests passed. **Files Changed**: * `apps/web/src/store/useWarRoomStore.ts` - added health diagnostic state/action, duplicate guard, stale-result guard, and cleanup paths. * `apps/web/tests/warRoomStore.test.ts` - added health diagnostic in-flight, stale reset, and rate-limit coverage. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T010 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded store diagnostic implementation. **BQC Fixes**: * Duplicate action prevention: `checkWorkerHealth` exits while a health check is already in flight (`apps/web/src/store/useWarRoomStore.ts`). * State freshness on re-entry: stale health results are discarded if the Worker URL input changes before the health response arrives (`apps/web/src/store/useWarRoomStore.ts`). ### Task T011 - Render Worker diagnostics in the War Room panel **Started**: 2026-05-30 02:18 **Completed**: 2026-05-30 02:23 **Duration**: 5 minutes **Notes**: * Added a Worker diagnostics section with a guarded health-check button, accessible status/alert region, source/service metadata, full rate-limit copy, and explicit privacy boundary text. * Covered healthy and rate-limited UI states, local-only disabled behavior, accessible status labels, and sensitive-data absence. * Ran `npx vitest run apps/web/tests/WarRoomPanel.test.tsx apps/web/tests/warRoomStore.test.ts apps/web/tests/warRoomClient.test.ts apps/web/tests/warRoomDiagnostics.test.ts`; 42 tests passed. **Files Changed**: * `apps/web/src/components/WarRoomPanel.tsx` - rendered diagnostics controls and visible health/failure states. * `apps/web/tests/WarRoomPanel.test.tsx` - added diagnostics UI coverage. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T011 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded UI diagnostic implementation. **BQC Fixes**: * Accessibility and platform compliance: diagnostics render through a native button plus `role="status"`/`role="alert"` regions with accessible labels (`apps/web/src/components/WarRoomPanel.tsx`). * Error information boundaries: panel tests confirm rate-limited diagnostics do not render account-like host fragments, private paths, or raw secrets (`apps/web/tests/WarRoomPanel.test.tsx`). ### Task T012 - Add post-deploy Worker health smoke check **Started**: 2026-05-30 02:23 **Completed**: 2026-05-30 02:26 **Duration**: 3 minutes **Notes**: * Added a GitHub Actions post-deploy health smoke check with an 8-second abort timeout. * The check validates compact health metadata and logs only service, deployment type, and rate-limit enabled/disabled state; it does not print secrets, account ids, request bodies, URLs, or raw response bodies. * Ran `ruby -e "require 'yaml'; YAML.load_file('.github/workflows/warroom-deploy.yml'); puts 'yaml ok'"`; YAML parsed successfully. **Files Changed**: * `.github/workflows/warroom-deploy.yml` - added bounded secret-safe health smoke check after Worker deploy. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T012 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded workflow smoke-check evidence. **BQC Fixes**: * External dependency resilience: deploy smoke check uses an explicit timeout and fails the workflow with bounded error text on unreachable, non-OK, malformed, or incomplete health responses (`.github/workflows/warroom-deploy.yml`). * Error information boundaries: workflow logs compact metadata only and avoids raw health bodies or URL echo (`.github/workflows/warroom-deploy.yml`). ### Task T013 - Update environment example for Worker diagnostics **Started**: 2026-05-30 02:26 **Completed**: 2026-05-30 02:29 **Duration**: 3 minutes **Notes**: * Added `VITE_FACTIONOS_WARROOM_WORKER_URL` as an optional browser-safe Worker default that can be left blank for local-only mode. * Added local Wrangler URL and health URL reference variables for operator diagnostics. * Preserved Cloudflare credentials as deploy/operations-only values and kept deployed Worker health URL variables documented without real secrets. **Files Changed**: * `.env.local.example` - documented browser-safe Worker default, local Wrangler diagnostics, and deployed health URL behavior. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T013 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded environment example update. ### Task T014 - Update environment documentation **Started**: 2026-05-30 02:29 **Completed**: 2026-05-30 02:32 **Duration**: 3 minutes **Notes**: * Added `VITE_FACTIONOS_WARROOM_WORKER_URL` as an active optional web variable and documented local-only fallback behavior. * Added local Wrangler URL and health URL references. * Clarified that Cloudflare credentials and ids are deploy/operations inputs only and must not be exposed to the browser. * Updated the data boundary to describe optional Worker diagnostics and allowlisted redacted federation rather than the stale not-fully-wired wording. **Files Changed**: * `docs/environments.md` - aligned active Worker variables, operational Cloudflare variables, and future hosted-service boundaries. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T014 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded environment docs update. ### Task T015 - Update deployment and API docs **Started**: 2026-05-30 02:32 **Completed**: 2026-05-30 02:37 **Duration**: 5 minutes **Notes**: * Updated deploy validation to use bounded health probes and documented the GitHub Actions health smoke check. * Documented local Wrangler health checks, compact health response metadata, app-level rate limits, current WAF posture, socket upgrade checks, and Worker rollback commands. * Updated the API reference for `/health`, `/rooms`, `/join`, `/approve`, `/reject`, and socket behavior, including rate-limit headers and safe socket failure codes. * Removed stale web-panel stub wording from the current Worker API/deployment sections. **Files Changed**: * `docs/deployment.md` - added deploy smoke, local Wrangler, health metadata, socket check, and rollback guidance. * `docs/api/README_api.md` - updated War Room Worker API reference for current room, reject, socket, health, and federation behavior. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T015 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded deployment/API documentation update. ### Task T016 - Update architecture, privacy, and release guidance **Started**: 2026-05-30 02:37 **Completed**: 2026-05-30 02:43 **Duration**: 6 minutes **Notes**: * Updated architecture docs to describe optional Worker room lifecycle, diagnostics, approval, presence, reconnect, bounded catch-up, and allowlisted redacted federation. * Updated privacy docs for current Worker diagnostics, safe health metadata, sender-excluded redacted federation, and local-only fallback states. * Updated release guidance with War Room typecheck/test/deploy-smoke/health-probe checks and forbidden claims around hosted identity, trusted erasure, public replay hosting, hosted storage, and analytics. * Rechecked the edited docs for stale web-panel stub wording. **Files Changed**: * `docs/ARCHITECTURE.md` - aligned current Worker/web architecture and remaining gaps. * `docs/privacy-and-security.md` - updated War Room external transfer controls and Cloudflare notes. * `docs/release.md` - added War Room diagnostic and deploy checks to release readiness notes. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T016 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded architecture/privacy/release documentation update. ### Task T017 - Create War Room operations runbook **Started**: 2026-05-30 02:43 **Completed**: 2026-05-30 02:48 **Duration**: 5 minutes **Notes**: * Created an operations runbook covering custom-domain and workers.dev health checks, local Wrangler checks, deploy smoke behavior, room and socket checks, rate-limit and WAF posture, Wrangler tail, rollback, browser diagnostics, and privacy-safe incident notes. * Explicitly documented that rollback and leave/reset do not provide trusted erasure. **Files Changed**: * `docs/runbooks/war-room-operations.md` - created War Room operations runbook. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T017 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded runbook creation. ### Task T018 - Update web README War Room boundaries **Started**: 2026-05-30 02:48 **Completed**: 2026-05-30 02:51 **Duration**: 3 minutes **Notes**: * Documented `VITE_FACTIONOS_WARROOM_WORKER_URL`, browser localStorage override/clear behavior, diagnostics UI states, safe health metadata, and privacy exclusions. * Noted that Session 07 still owns end-to-end browser evidence and final War Room phase closeout. **Files Changed**: * `apps/web/README_web.md` - updated web War Room diagnostics and validation boundaries. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T018 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded web README update. ### Task T019 - Add enriched health client tests **Started**: 2026-05-30 02:51 **Completed**: 2026-05-30 02:54 **Duration**: 3 minutes **Notes**: * Expanded client tests for sanitized enriched health parsing, invalid health URLs, `Retry-After` header mapping, malformed health metadata, timeout/offline/rate-limit states, and sensitive-data absence. * Ran `npx vitest run apps/web/tests/warRoomClient.test.ts`; 11 tests passed. **Files Changed**: * `apps/web/tests/warRoomClient.test.ts` - added focused client health diagnostics coverage. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T019 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded client test evidence. **BQC Fixes**: * Contract alignment: tests require sanitized enriched health responses and malformed health rejection (`apps/web/tests/warRoomClient.test.ts`). ### Task T020 - Add store and panel diagnostic tests **Started**: 2026-05-30 02:54 **Completed**: 2026-05-30 02:57 **Duration**: 3 minutes **Notes**: * Store tests cover health diagnostics, in-flight guards, stale Worker URL cleanup, and rate-limit diagnostics. * Panel tests cover the diagnostics status region, healthy/rate-limited copy, disabled local-only state, and sensitive-data absence. * Ran `npx vitest run apps/web/tests/warRoomStore.test.ts apps/web/tests/WarRoomPanel.test.tsx`; 27 tests passed. **Files Changed**: * `apps/web/tests/warRoomStore.test.ts` - added store diagnostic coverage. * `apps/web/tests/WarRoomPanel.test.tsx` - added diagnostics UI and privacy coverage. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T020 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded store/panel test evidence. **BQC Fixes**: * Duplicate action prevention: tests confirm only one health request is made while a health check is in flight (`apps/web/tests/warRoomStore.test.ts`). * Accessibility and platform compliance: panel tests require an accessible diagnostics status region (`apps/web/tests/WarRoomPanel.test.tsx`). ### Task T021 - Update cross-package documentation consistency **Started**: 2026-05-30 02:57 **Completed**: 2026-05-30 03:02 **Duration**: 5 minutes **Notes**: * Updated workflow documentation for the War Room deploy health smoke check. * Updated the War Room README for health metadata, deploy smoke behavior, local health checks, current web diagnostics, and remaining non-goals. * Updated the incident-response runbook to link the War Room operations runbook and remove stale stub guidance. * Updated hosted-services notes for current optional Worker diagnostics and redacted federation boundaries. * Ran a stale wording scan across current docs/package docs/workflow docs; only the historical ADR retains the original accepted context. **Files Changed**: * `.github/workflows/README_workflows.md` - documented War Room deploy smoke behavior. * `apps/warroom/README_warroom.md` - documented enriched health metadata, deploy checks, local checks, and integration boundaries. * `docs/runbooks/incident-response.md` - linked the War Room operations runbook and updated response steps. * `docs/hosted-services.md` - aligned optional Cloudflare Worker hosted boundary with current source. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T021 complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded cross-doc consistency update. ### Task T022 - Run final focused validation **Started**: 2026-05-30 03:02 **Completed**: 2026-05-30 03:08 **Duration**: 6 minutes **Notes**: * Ran focused Worker/web tests: `npx vitest run apps/web/tests/warRoomDiagnostics.test.ts apps/web/tests/warRoomClient.test.ts apps/web/tests/warRoomIdentity.test.ts apps/web/tests/warRoomStore.test.ts apps/web/tests/WarRoomPanel.test.tsx apps/warroom/tests/warroom.test.ts apps/warroom/tests/worker.test.ts`; 89 tests passed. * Ran package typechecks: `npm --workspace @factionos/web run typecheck` and `npm --workspace @factionos/warroom run typecheck`; both passed. * Reviewed workflow YAML with Ruby YAML parser; passed. * Ran Biome lint on touched source/workflow files; passed. * Ran `npm run security:secrets`; passed across 729 tracked text files. * Ran current-doc stale stub scan excluding historical ADRs; no matches. * Ran ASCII/LF validation across changed and untracked session files; passed. * Ran `git diff --check`; passed. * Added `IMPLEMENTATION_SUMMARY.md` for session closeout. **Files Changed**: * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/tasks.md` - marked T022 and completion checklist complete. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/implementation-notes.md` - recorded final validation evidence. * `.spec_system/specs/phase05-session06-deployment-environment-and-diagnostics/IMPLEMENTATION_SUMMARY.md` -
