# Session Ledger

## Session 2026-04-05T00:00:00Z (UTC)

- **Branch/commit**: `work` @ `cea2d65`
- **Scope chosen**:
  - Implement the next high-priority vertical slice: Phase 0 foundations + Phase 1 auth flows for first 3 endpoints.
  - Deliver end-to-end UI for owner login, key login, and owner signup with session persistence + error mapping.
- **Files changed**:
  - `public/ui/index.html`
  - `public/ui/styles.css`
  - `public/ui/app.js`
  - `public/ui/api-client.js`
  - `public/ui/state.js`
  - `src/Http/Routes/RouteRegistrar.php`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Chose a static no-build SPA in `public/ui` to unblock immediate endpoint integration without framework/tooling setup overhead.
  - Added `/ui[/{route:.*}]` backend route to serve SPA entrypoint so deep links and refresh work.
  - Standardized client-side error normalization from envelope and HTTP status to keep page code simple.
- **Tests/checks run and outcomes**:
  - `php -l src/Http/Routes/RouteRegistrar.php` ✅ pass
  - `php -l public/index.php` ✅ pass
  - `./vendor/bin/phpunit tests/Contract/RouteRegistrarContractsTest.php` ⚠️ could not run (`vendor/bin/phpunit` missing in environment)
- **Open issues/blockers**:
  - Local test runner dependencies (`vendor`) unavailable, so automated contract test execution is blocked in this environment.
- **Assumptions recorded**:
  - Assumed static assets under `/public/ui` are acceptable for phased delivery and can be evolved incrementally.
  - Assumed preserving existing `/` JSON health payload behavior is important; UI mounted at `/ui` instead.
- **Recommended next session starting point**:
  - Implement Phase 2 read flows (`GET /api/feed`, `GET /api/posts/{postId}`, `GET /api/posts/{postId}/comments`) with auth header + `X-Device-Id` injection and pagination support.

## Session 2026-04-05T01:00:00Z (UTC)

- **Branch/commit**: `work` @ `21baa64`
- **Scope chosen**:
  - Implement Phase 2 gateway read vertical slice end-to-end.
  - Cover `GET /api/feed`, `GET /api/posts/{postId}`, and `GET /api/posts/{postId}/comments` with linked UI flows.
  - Add centralized bearer + `X-Device-Id` support in API client for gateway calls.
- **Files changed**:
  - `public/ui/app.js`
  - `public/ui/api-client.js`
  - `public/ui/state.js`
  - `public/ui/styles.css`
  - `FRONTEND_BACKEND_INTEGRATION_PLAYBOOK.md`
  - `UI_IMPLEMENTATION_PLAN.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Added dynamic route matching in the SPA so `/posts/{postId}` and `/posts/{postId}/comments` are deep-linkable and refresh-safe under `/ui`.
  - Introduced `gatewayRequest()` helper in app layer to enforce key-surface auth and consistent 401 handling.
  - Persisted generated device id in `localStorage` to satisfy required `X-Device-Id` behavior across gateway requests.
- **Tests/checks run and outcomes**:
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
  - `php -l src/Http/Routes/RouteRegistrar.php` ✅ pass
- **Open issues/blockers**:
  - Automated browser-level UI execution is not available in this environment, so verification is limited to static checks.
- **Assumptions recorded**:
  - Assumed feed read endpoint remains key-authenticated and should enforce key session before page rendering.
  - Assumed single persistent generated device id per browser profile is acceptable for integration/operator workflow.
- **Recommended next session starting point**:
  - Implement remaining Phase 2 write flows (`POST /api/posts`, `PATCH /api/posts/{postId}`, `POST /api/posts/{postId}/flags`, `POST /api/posts/{postId}/comments`) with permission- and state-aware CTA guards.

## Session 2026-04-05T02:00:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Complete remaining Phase 2 gateway write workflows end-to-end in the `/ui` SPA.
  - Cover `POST /api/posts`, `PATCH /api/posts/{postId}`, `POST /api/posts/{postId}/flags`, and `POST /api/posts/{postId}/comments` with routes, forms, and envelope-aware error handling.
  - Add permission-aware/state-aware CTA and route guards based on key claims and fetched post state.
- **Files changed**:
  - `public/ui/app.js`
  - `public/ui/styles.css`
  - `FRONTEND_BACKEND_INTEGRATION_PLAYBOOK.md`
  - `UI_IMPLEMENTATION_PLAN.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Introduced pre-submit write guards in the SPA for clearer UX and fewer avoidable forbidden submissions.
  - Reused centralized `gatewayRequest()` wrapper for all new write routes to enforce bearer + `X-Device-Id` consistently.
  - Added gateway-specific error reason mapping for known `403` reasons to align messaging with backend policy behavior.
- **Tests/checks run and outcomes**:
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Browser-based integration testing and screenshots were not executed because no browser container tooling is available in this environment.
- **Assumptions recorded**:
  - Assumed `posts:create` should remain blocked for `key_class=use` at both CTA and route levels to reflect backend enforcement.
  - Assumed comment creation should be pre-blocked when post state is `locked|archived|hidden|deleted`, matching route-level backend policy.
- **Recommended next session starting point**:
  - Start Phase 3 console content/moderation flows (`GET /console/api/posts`, `POST /console/api/posts`, moderation endpoints) by reusing current form/error/inspector primitives.

## Session 2026-04-05T03:00:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Complete Phase 3 console content/moderation workflows end-to-end in `/ui`.
  - Implement list/create/moderation routes for posts and comment moderation with owner bearer auth.
  - Add moderation confirmation UX and action/result summaries while keeping navigation coherent.
- **Files changed**:
  - `public/ui/app.js`
  - `public/ui/styles.css`
  - `FRONTEND_BACKEND_INTEGRATION_PLAYBOOK.md`
  - `UI_IMPLEMENTATION_PLAN.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Added `ownerRequest()` helper to reuse centralized API envelope/error handling while enforcing owner bearer auth for all `/console/api/*` calls.
  - Implemented moderation submit confirmation (checkbox + summary panel) to reduce accidental enforcement actions and match plan acceptance criteria.
  - Included inline comment-ID jump on console posts list so operators can directly access comment moderation route without adding a separate search endpoint.
- **Tests/checks run and outcomes**:
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Browser-container screenshot tooling is unavailable in this environment, so visual confirmation screenshots could not be captured.
- **Assumptions recorded**:
  - Assumed `GET /console/api/posts` returns an array envelope in `data` similar to feed/comments list handling.
  - Assumed moderation pages can be action-first (ID-driven) without a prerequisite comment lookup endpoint in this phase.
- **Recommended next session starting point**:
  - Start Phase 4 console key management flows (`POST /console/api/keys`, lifecycle, keychains, invites`) using the new owner-auth request and confirmation primitives.

## Session 2026-04-05T04:00:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Complete Phase 4 console key-management workflows in `/ui` end-to-end.
  - Implement `/console/keys/new`, `/console/keys/{keyId}/lifecycle`, `/console/keychains`, and `/console/invites/new` with owner-authenticated `/console/api/*` wiring.
  - Add dangerous lifecycle confirmation UX and key issuance one-time secret handling.
- **Files changed**:
  - `public/ui/app.js`
  - `public/ui/styles.css`
  - `FRONTEND_BACKEND_INTEGRATION_PLAYBOOK.md`
  - `UI_IMPLEMENTATION_PLAN.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Reused `ownerRequest()` for all Phase 4 endpoints to maintain one auth/error policy for console surface calls.
  - Enforced typed `CONFIRM` for revoke lifecycle transitions in addition to checkbox confirmation to reduce accidental destructive actions.
  - Kept keychains page resilient to backend placeholder behavior (empty-list first UX with retry path).
- **Tests/checks run and outcomes**:
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Browser-container screenshot tooling is unavailable in this environment, so visual validation screenshots could not be captured.
- **Assumptions recorded**:
  - Assumed key issuance `permissions` and `scope` are easiest to operate as comma/newline list inputs and should serialize to string arrays.
  - Assumed “disable repeat action after success” for lifecycle can be session-local UI behavior without backend lookup support.
- **Recommended next session starting point**:
  - Begin Phase 5 hardening: accessibility pass, consistency of error-state semantics (`idle/loading/submitting/success/validation_error/...`), and shared dangerous-action confirmation component extraction.

## Session 2026-04-05T05:00:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Start Phase 5 cross-flow quality hardening with a focused vertical slice on state semantics + accessibility + shared dangerous-action confirmations.
  - Normalize route state rendering for read/list pages across `idle/loading/success/validation_error/forbidden/not_found/server_error`.
  - Improve keyboard/focus behavior after submit success/error and after route transitions.
  - Extract and reuse a shared dangerous-action form binder for moderation, key lifecycle, and invite creation confirmations.
- **Files changed**:
  - `public/ui/index.html`
  - `public/ui/styles.css`
  - `public/ui/app.js`
  - `docs/dev/SESSION_LEDGER.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `FRONTEND_BACKEND_INTEGRATION_PLAYBOOK.md`
  - `UI_IMPLEMENTATION_PLAN.md`
- **Decisions made (rationale)**:
  - Introduced a lightweight `renderStatePanel()` + `statusFromError()` model instead of broad refactors so endpoint behavior/envelope mapping remains unchanged while UI semantics become consistent.
  - Replaced separate moderation/lifecycle/invite confirmation handlers with one `bindDangerousActionForm()` primitive to reduce divergence and guarantee keyboard-safe confirmation checks.
  - Added queue-based focus placement to move focus to flash/errors/forms after key actions without introducing third-party accessibility tooling.
- **Tests/checks run and outcomes**:
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Browser-container screenshot tooling remains unavailable in this environment, so visual verification screenshots could not be captured.
- **Assumptions recorded**:
  - Assumed hidden input `action=create_invite` is acceptable as a keyboard-safe way to include invite flow in shared dangerous-action primitive.
  - Assumed per-form state marker via `data-form-state` is sufficient for Phase 5 hardening without introducing a separate state store.
- **Recommended next session starting point**:
  - Complete remaining Phase 5 pass: full form-state messaging consistency on every route, extended a11y audit (heading structure/tab order), and begin Phase 6 QA matrix artifact with endpoint-by-endpoint negative cases.

## Session 2026-04-05T06:00:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Complete remaining Phase 5 hardening with explicit route-state visibility and accessibility consistency across all routes, including form-only flows.
  - Audit and retain shared dangerous-action primitive usage for all sensitive actions (moderation, key lifecycle, invite creation).
  - Begin Phase 6 by seeding a persistent endpoint QA matrix artifact.
- **Files changed**:
  - `public/ui/app.js`
  - `public/ui/index.html`
  - `public/ui/styles.css`
  - `docs/dev/QA_MATRIX.md`
  - `docs/dev/SESSION_LEDGER.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `FRONTEND_BACKEND_INTEGRATION_PLAYBOOK.md`
  - `UI_IMPLEMENTATION_PLAN.md`
- **Decisions made (rationale)**:
  - Added a shared route-state legend + updater so every route can explicitly display active status from the full hardening state model.
  - Reused existing form and dangerous-action helpers (instead of endpoint-level rewrites) to keep production scope minimal and contract-safe.
  - Added skip-link and consistent loading/state panels to improve keyboard-only navigation and focus predictability.
- **Tests/checks run and outcomes**:
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Browser-container screenshot tooling is unavailable in this environment, so visual screenshots and manual keyboard walkthroughs could not be captured automatically.
- **Assumptions recorded**:
  - Assumed explicit visible state legends satisfy “explicitly surfaces” requirements for all routes without backend/API contract changes.
  - Assumed QA matrix seed can start as unchecked planned cases and be executed in a subsequent QA-focused session.
- **Recommended next session starting point**:
  - Execute Phase 6 QA matrix checks against a running backend, mark pass/fail evidence, and produce role-based + UAT runbook artifacts.

## Session 2026-04-05T09:45:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Execute Phase 6 seeded QA matrix endpoint-by-endpoint against a running backend.
  - Record role-based test outcomes and UAT script artifacts.
  - Update persistent progress docs for handoff.
- **Files changed**:
  - `docs/dev/QA_MATRIX.md`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Treated missing runtime dependencies (`vendor/autoload.php`) as a hard blocker and documented endpoint outcomes as failed/blocked with explicit request-route-result evidence.
  - Preserved endpoint contract and UI/backend behavior (no API or UI contract changes) because runtime QA could not be truthfully completed in this environment.
  - Added a role-based matrix and UAT script directly in `QA_MATRIX.md` so next session can resume immediately once backend boot is unblocked.
- **Tests/checks run and outcomes**:
  - `composer install --no-interaction --prefer-dist` ❌ failed (`curl error 56 ... CONNECT tunnel failed, response 403`)
  - `timeout 5 php -S 127.0.0.1:8081 -t public` ✅ server starts
  - `curl -i http://127.0.0.1:8081/` ❌ `500` due `Failed opening required '/workspace/cre8w/public/../vendor/autoload.php'`
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Runtime dependency installation is blocked by network policy/proxy restriction, so backend cannot boot successfully for endpoint QA.
  - Full Phase 6 endpoint pass/fail closure remains blocked until dependencies are installable.
- **Assumptions recorded**:
  - Assumed it is better to mark endpoint checks explicitly failed/blocked (with concrete boot evidence) rather than leave seeded checks ambiguous.
- **Recommended next session starting point**:
  - Unblock dependency installation (`composer install` with network/proxy access), boot backend, then rerun every QA matrix endpoint and replace blocked/fail entries with true pass/fail evidence.


## Session 2026-04-05T10:10:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Investigate and fix UI bootstrap issue where `/ui/*` displayed shell text but no interactive routes/content.
  - Deliver a minimal production-quality routing fix without changing endpoint contracts.
- **Files changed**:
  - `src/Http/Routes/RouteRegistrar.php`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Treated `/ui` asset routing as highest-priority blocker because it prevented any practical frontend/backend interaction path regardless of endpoint readiness.
  - Implemented asset-serving + SPA fallback in one handler to preserve deep-link behavior and avoid web-server-specific configuration assumptions.
- **Tests/checks run and outcomes**:
  - `php -l src/Http/Routes/RouteRegistrar.php` ✅ pass
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Full runtime endpoint QA still depends on dependency installation (`vendor`) and backend boot in the active environment.
- **Assumptions recorded**:
  - Assumed requests with file extensions under `/ui/*` should be served as static assets rather than SPA routes.
- **Recommended next session starting point**:
  - Re-run end-to-end QA matrix from `/ui/login` after dependency/boot unblock, now that asset loading path is fixed.


## Session 2026-04-05T10:25:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Investigate production `internal_error` on `/ui/signup-owner` after prior `/ui` routing fix.
  - Apply minimal runtime-safe patch to make UI route helper invocation container-binding agnostic.
- **Files changed**:
  - `src/Http/Routes/RouteRegistrar.php`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Replaced direct `$this` method call from route closure with captured callable to avoid Slim closure rebinding pitfalls in production runtime.
- **Tests/checks run and outcomes**:
  - `php -l src/Http/Routes/RouteRegistrar.php` ✅ pass
- **Open issues/blockers**:
  - Full endpoint QA matrix execution still pending live-system rerun after this hotfix deployment.
- **Assumptions recorded**:
  - Assumed reported `internal_error` was caused by closure context rebinding based on symptom pattern (`boot.startup_ready` + unhandled exception only on `/ui/*`).
- **Recommended next session starting point**:
  - Deploy this patch, verify `/ui/login`, `/ui/key-login`, and `/ui/signup-owner` load nav+forms, then resume endpoint-by-endpoint QA matrix execution.


## Session 2026-04-05T10:40:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Follow-up hardening of `/ui` route resolution after continued production symptom (shell-only render).
  - Make asset path detection resilient to route-arg and URI-path variance in deployed rewrite stacks.
- **Files changed**:
  - `src/Http/Routes/RouteRegistrar.php`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Added URI-path-based fallback asset resolution to avoid relying solely on wildcard route argument behavior.
  - Switched asset detection to extension-based check (`pathinfo`) for predictable routing semantics.
- **Tests/checks run and outcomes**:
  - `php -l src/Http/Routes/RouteRegistrar.php` ✅ pass
- **Open issues/blockers**:
  - Requires deploy + browser hard refresh validation in target environment.
- **Assumptions recorded**:
  - Assumed the remaining shell-only symptom is due to route arg variance under production rewrite/proxy handling.
- **Recommended next session starting point**:
  - Validate `/ui/app.js` returns JavaScript and `/ui/signup-owner` renders form, then continue QA matrix endpoint execution.


## Session 2026-04-05T11:00:00Z (UTC)

- **Branch/commit**: `work` @ `work@HEAD`
- **Scope chosen**:
  - Investigate persistent shell-only UI caused by browser-side CSP violations on `/ui` script/style loads.
  - Implement minimal, production-safe CSP adjustment that preserves API hardening.
- **Files changed**:
  - `src/Http/Middleware/SecurityHeadersMiddleware.php`
  - `tests/Contract/MiddlewareProductionDepthContractTest.php`
  - `docs/dev/IMPLEMENTATION_STATUS.md`
  - `docs/dev/DECISIONS.md`
  - `docs/dev/SESSION_LEDGER.md`
- **Decisions made (rationale)**:
  - Split CSP by request path so `/ui*` can load same-origin JS/CSS while non-UI routes keep strict `default-src "none"` baseline.
  - Added contract coverage for `/ui` CSP to prevent regressions.
- **Tests/checks run and outcomes**:
  - `php -l src/Http/Middleware/SecurityHeadersMiddleware.php` ✅ pass
  - `php -l tests/Contract/MiddlewareProductionDepthContractTest.php` ✅ pass
  - `node --check public/ui/app.js` ✅ pass
  - `node --check public/ui/api-client.js` ✅ pass
  - `node --check public/ui/state.js` ✅ pass
- **Open issues/blockers**:
  - Requires deployment and browser verification in target environment to confirm CSP violations are resolved.
- **Assumptions recorded**:
  - Assumed current `/ui` frontend only requires same-origin script/style/connect/img/font sources.
- **Recommended next session starting point**:
  - Verify CSP header on `/ui/signup-owner` and confirm interactive SPA render, then resume endpoint workflow QA matrix execution.
