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.

When deploy.sh runs via sudo, git tried to use root's SSH key which
doesn't have Bitbucket access. Now detects repo owner and runs git
commands as that user so the user's SSH key is used.

Previously the git fetch/reset block was commented out and the script only
deployed whatever was already in the repo dir. Uncommented it and added
git config core.fileMode false to prevent permission-drift merge conflicts.

- 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

- Import langdetect with graceful fallback if not installed
- _check_language(): detect actual document language via langdetect on first
3 pages of text; store in self._detected_lang; warn when declared /Lang tag
doesn't match detected language; suggest correct BCP-47 tag when missing
- _check_readability(): skip Flesch Reading Ease / Flesch-Kincaid (English-only
formulas) for non-English documents; long-sentence check remains language-agnostic
- _check_links(): extend unclear-link patterns to Ukrainian, Russian, German,
French, Spanish, and Polish
- requirements-cloudrun.txt: add langdetect>=1.0.9

.score-display had overflow:hidden which cut off the right half of the
btn-recheck button. Changed to overflow:visible — decorative ::before
and ::after pseudo-elements use position:absolute;inset:0 so they remain
visually contained within the border-radius.

pdf_remediation.py:
- _suggest_title() now detects temp filenames (tmp + random chars) and
extracts the first line of content instead of using the useless
temp name (e.g. "Tmp9H15Ocsl" → actual document text)
report_generator.py — HTML report:
- Add skip-to-main-content link (WCAG 2.4.1)
- Wrap content in <main id="main-content"> landmark
- Proper <header>/<footer> semantic elements
- <section> + aria-labelledby on each card
- Tables: <caption>, scope="col" on all <th> (WCAG 1.3.1)
- Severity badges: aria-label="Severity: X", class-based color
(not inline style) so not color-only (WCAG 1.4.1)
- Score ring: role="img" + aria-label with numeric value + grade
- Stats grid: role="group" + aria-label
- Improved contrast: stat labels #475569 not #64748b
- @media (prefers-reduced-motion) block
- Links on WCAG criterion column
report_generator.py — PDF report HTML:
- Add <title> and <meta name="description"> to <head>
- <header role="banner">, <main>, <footer> semantic elements
- Matterhorn/issues tables: <caption>, scope="col" on <th>
- Score block: role="img" + aria-label
- Stats: role="group" + aria-label
- "Not tested" text instead of "—" in status cells

Each issue card's WCAG criterion (e.g. "1.4.3") is now a link to the
WAI Understanding page at w3.org. Comma-separated multi-criteria and
PDF/UA are handled separately. Links open in a new tab.
- js/utils.js: WCAG_SLUGS map + wcagCriterionLinks() helper
- js/results.js: issue-meta now calls wcagCriterionLinks()
- css/styles.css: .wcag-link style (dotted underline, hover accent)

Replaced full-page text scan with annotation-based extraction — now only
checks the text inside actual URI hyperlink bounding boxes, eliminating
false positives from vague words in body prose.

Page viewer:
- loadVisualPage() now accepts highlightNum; highlights marker after image onload
(was using fixed 300ms timeout which fired before GCS image finished loading)
- viewOnPage() passes markerNum directly to loadVisualPage()
Image analysis:
- Quality concerns downgraded WARNING → INFO (advisory, not WCAG violations)
- Cap at 2 concerns per image (was unlimited)
- Google Vision label detections removed — not actionable accessibility issues

- run_check() wraps each check in a ThreadPoolExecutor future with a timeout
- Heavy checks: Image 180s, OCR 180s, Color Contrast 120s, veraPDF 120s
- Default per-check timeout: 90s
- Timed-out checks emit WARNING instead of hanging the whole request
- Cloud Run service timeout raised to 3600s (gcloud run services update)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Cloud Run processes PDFs synchronously (2-5 min). The await startCheck()
call blocks JS, so progress never advanced past 30%. Add a setInterval
timer before the await that advances through realistic stages every 18s,
covering the full processing window. Timer is cleared on completion/error.

Keep dismissed_indices injection in handleResult() from our QA
fixes alongside the Cloud Run rewrite from origin/master.

- Downgrade readability ERROR → WARNING (advisory, not hard failure)
Part 4 — Auto-fix debugging:
- Remediation failure now returns up to 2000 chars of log (was 500)
- pdf_remediation.py: stderr output, sys.exit(0/1), output dir creation
Part 5 — Error location: View on Page button on each issue card
Part 6 — Matterhorn Protocol PDF/UA-1:
- _build_matterhorn_summary() maps 19 checks → 31 checkpoints

Remove stale Redis/worker references, add Cloud Run and rate_limits
config. Comment out git pull section for manual control.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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

Issue Numbering System:
📍 Issues with visual markers now show #1, #2, #3, etc.
- Yellow badge "📍#5" appears on issues with page locations
- Click badge to jump to Visual Page Inspector and highlight marker
- Numbers correlate between issue list and page markers
Smart Marker Grouping:
🎯 Multiple issues at same location = ONE marker
- Example: 8 issues on one image → Shows "1+7" badge
- Hover shows ALL issues at that location in tooltip
- Prevents marker overlap and clutter
- First issue number + count of additional issues
Table Coordinate Support:
📊 Tables now have visual markers
- Extract bounding box from pdfplumber find_tables()
- Tables highlighted with orange warning boxes
- Each table gets its own marker
Enhanced Tooltips:
💬 Hover markers to see multiple issues:
- Lists all issues at that coordinate
- Shows severity, description, and fix for each
- Scrollable for locations with many issues
- "3 issues at this location:" header
Interactive Features:
- Click 📍#5 badge in issue list → jumps to page & pulses marker
- Hover marker → see all issues there
- Larger badges for multi-issue locations (18px vs 16px)
- White stroke around badges for better visibility
Result: Page 1 with 3 images & 24 issues = 3 clean markers instead of 24!
