๐Ÿšจ Severity: HIGH
๐Ÿ’ก Vulnerability: The component library gallery (components/index.html) lacked a Content Security Policy (CSP), leaving it potentially vulnerable to XSS and framing attacks. It also relied heavily on inline scripts (<script>...) and inline styles (<style>...</style>, style="...").
๐ŸŽฏ Impact: An attacker could potentially inject malicious scripts or styles into the component gallery context, or embed the page maliciously.
๐Ÿ”ง Fix:

  1. Added a strict CSP meta tag (default-src 'self', object-src 'none', style-src 'self', etc.) and a Referrer-Policy to components/index.html.
  2. Extracted the inline <script> into components/krds-gallery.js and loaded it with defer.
  3. Extracted the inline <style> into components/krds-gallery.css.
  4. Refactored inline style="..." HTML attributes into reusable CSS utility classes (e.g., .mt-16, .max-w-320) in krds-gallery.css.
  5. Permitted data: URIs in img-src to allow the inline SVG icons used within krds-components.css.
    โœ… Verification: Playwright tests confirm that the console no longer throws CSP blocking errors when loading the gallery.

๐Ÿ‘‹ Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a ๐Ÿ‘€ emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Pull request overview

OpenCode reviewed the current-head mergeability evidence and changed-file flow before approval, then found merge conflicts on the affected path.

Findings

1. HIGH Merge Conflict Guidance - Resolve the PR branch against the latest base branch

  • Problem: GitHub reports mergeStateStatus DIRTY for this pull request.
  • Root cause: Branch sentinel/strict-csp-component-gallery-18356632995419362895 cannot be merged cleanly into main; the changed-file flow below shows which review/runtime path is blocked by the conflict.
  • Fix: Merge or rebase the latest main into sentinel/strict-csp-component-gallery-18356632995419362895, resolve conflict markers in the PR branch, rerun the focused checks, and push the same branch.
  • Repair commands:
gh pr checkout 77 --repo ContextualWisdomLab/ContextualWisdomLab.github.io
git fetch origin main
git merge --no-ff origin/main  # or: git rebase origin/main
git status --short
# resolve files, then git add <resolved-files>
# merge path: git commit
# rebase path: git rebase --continue
git push origin HEAD:sentinel/strict-csp-component-gallery-18356632995419362895
# rebase path only: git push --force-with-lease origin HEAD:sentinel/strict-csp-component-gallery-18356632995419362895
  • Regression test: Keep OpenCode approval gated on mergeability so model-output failures cannot approve a conflicted PR.

Pull request overview

OpenCode could not approve from deterministic current-head evidence because GitHub Checks have failed.

Findings

1. HIGH Current-head GitHub Checks - Fix failed required checks before approval

  • Problem: Failed same-head checks remain for 7837ff379bc93eb0d30d70195c39fbf29935ce2b.
  • Root cause: The model-unavailable evidence fallback is allowed only when peer GitHub Checks are complete and clean.
  • Fix: Read and fix the failed check logs below, then rerun the current-head checks.
  • Regression test: Keep the model-unavailable fallback gated on an empty failed-check rollup.

Rebuilt on current main@4c9241c8de1fde19ae2646dbcb52e796feaa38e7 and pushed as exact head c175eba944c162667327340936b0dc472fc745a9.

Current-head changes and evidence:

  • Extracted all gallery inline style blocks, style attributes, and scripts into same-origin krds-gallery.css and krds-gallery.js.
  • Enforced default-src none, explicit same-origin script/style/font/connect directives, data images only, no object/base/form/frame targets, HTTPS upgrades, and Trusted Types.
  • Added strict referrer policy and regression guards for CSP directives, inline active content, event attributes, and unsafe DOM sinks.
  • TDD: 3 failures before the CSP extraction; 5 tests pass after the fix.
  • Coverage: 50 statements, 100 percent.
  • Trivy CRITICAL/HIGH/MEDIUM vulnerability, misconfiguration, and secret findings: 0.
  • Prior CodeQL failure was a no-source configuration error on the stale conflicting head; current main supplies Python test source for extraction.
  • Open review threads: 0.
