- enterprise_pdf_checker.py: resolve custom tag names through PDF RoleMap
in _check_headings so PDFs using /Heading1-style tags (mapped to /H1)
are correctly detected; add depth guard to walk_tree
- js/results.js: add CP14 (Heading Structure) to CP_TO_CHECK; relax
H-type restriction so M-type CPs with a linked check also get
Mark as Passed / Undo buttons
- api.php: add 'Heading Structure' => ['14'] to $check_to_cp for
server-side recalculate score with heading override
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
handleResult() now overlays accessibility_score/wcag_compliance from
.adjusted.json (if it exists) while keeping the original severity_counts
as the recalculation baseline — prevents double-subtraction.
displayResults() auto-calls applyScoreRecalc() on load when the result
was previously adjusted, restoring the (Adjusted) label and WCAG badges
without triggering another server save.

- Issue 1: Recompute WCAG A/AA compliance badges after dismissing issues (JS +
backend); exported reports now reflect updated pass/fail status
- Issue 2: Group document-wide table issues into collapsible cards with
Dismiss All button; reduces noise for multi-table documents
- Issue 3: Split cleanup retention — uploads deleted after 24h, result/meta
JSONs retained 30 days (RESULTS_RETENTION_HOURS env var, default 720h)
- Issue 4A: Library shows adjusted score when available (.adjusted.json preferred)
- Issue 4B: History page groups documents by retention countdown (red/yellow/green
sections); adds 30-day retention banner
- Issue 5+6: AI prompt updated — describe people by role/action not appearance,
use specific brand names; flags images with people for human review

- api.php: add save_adjusted_result action that merges dismissed issues,
check overrides and recalculated score into {job_id}.adjusted.json;
handleExport() now prefers .adjusted.json over .result.json
- js/results.js: displayMatterhorn() shows Mark as Passed / Undo buttons
for H-type CPs (CP04, CP13) linked to overridden checks; overrideCheck /
unoverrideCheck refresh Matterhorn table and recompute overall banner
- js/batch.js: exportReport() saves adjusted result before opening export
URL, using pre-opened window to avoid popup blockers
- report_generator.py: filter dismissed issues, show (Adjusted) badge,
Manual Pass in checks and Matterhorn tables; switch generate_html() to
Montserrat + Oliver branding (#1a1a1a header, #FFC407 skip-link)
- css/styles.css: fix dark-mode log-header from blue-ish #252840 to #242424

- api.php: read accessibility_score (not score) from result.json
- api.php: handleDelete() also removes .dismissed.json, .overrides.json, .error.log
- js/app.js: add Delete button to each history row with confirm dialog
- css/styles.css: red hover style for delete button

Jobs created before user isolation was added have null user_id.
Previously they were hidden from authenticated users. Now authenticated
users see their own jobs + all legacy jobs (no user_id). Jobs belonging
to a different authenticated user are still excluded.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- api.php: extractUserFromToken() decodes Azure AD JWT payload (oid/name/email)
- Upload: stores user_id, user_name, user_email in job .meta.json
- handleList(): filters jobs by authenticated user's oid — full user isolation
(jobs without user_id are excluded for authenticated users to prevent leakage);
enriches each entry with score, grade, critical/error counts from result JSON
- index.html: "My Documents" history section, shown after login
- js/app.js: showAuthenticatedUI() triggers loadHistory(); full renderHistory()
renders sortable table with score, grade, severity badges, and Open/HTML/PDF/JSON
action buttons; openHistoryJob() loads any past result into the results panel
- js/results.js: calls loadHistory() after displayResults() so table refreshes
immediately after a new check completes
- css/styles.css: history table styles with colour-coded score/grade/severity badges

Replace the Redis queue + Python worker daemon with a synchronous HTTP
call to a Cloud Run service, eliminating Redis and simplifying the
infrastructure from 4 containers (web, worker, redis, postgres) to just
web + postgres (with Cloud Run handling processing).
- Add cloudrun_service.py: Flask app wrapping EnterprisePDFChecker with
POST /check and GET /health endpoints, GCS image upload
- Add Dockerfile.cloudrun + requirements-cloudrun.txt for Cloud Run image
- Add cloudbuild.yaml for Cloud Build with custom Dockerfile
- Rewrite api.php: remove all Redis code, add Cloud Run OIDC auth
(getCloudRunToken), synchronous processing in handleCheck(), file-based
rate limiting, GCS redirect in handleImage(), DB helper updateJobInDatabase()
- Update js/upload.js: handle synchronous completed response from Cloud Run,
increase poll timeout to 15 minutes
- Update js/page-viewer.js: use GCS URLs directly for page images
- Simplify docker-compose.yml and docker-compose.prod.yml: remove worker
and redis services
- Remove PHP Redis extension from Dockerfile.web
- Set 900s timeouts across nginx, PHP-FPM, gunicorn, curl, and Cloud Run
- Update cleanup.py: remove result_images pattern (now on GCS), add
rate_limits cleanup
- Update .env.example: replace Redis vars with Cloud Run/GCS config
Cloud Run service deployed to:
https://pdf-checker-bcb6ipdqka-uc.a.run.app
GCS bucket: gs://optical-pdf-images (7-day lifecycle, public read)
GCP project: optical-414516
