📝 Walkthrough

Walkthrough

The change adds WCAG 2.2 AA and HTML5 requirements. Report templates now use semantic markup. Sanitization removes obsolete attributes and secures blank-target links. Pages add titles, and tests validate accessibility rules.

Changes

Accessibility compliance

Layer / File(s) Summary
Semantic report markup
assets/refactor-first-report.mustache, public/assets/refactor-first-report.mustache
Report headings, tables, navigation, charts, anchors, and spacing markup now use semantic HTML5 structures and CSS classes.
Sanitization, page metadata, and styles
lib/renderer.js, app/*/page.jsx, app/globals.css
DOMPurify removes obsolete attributes and adds security attributes to blank-target links. Static pages export metadata titles. Styles update the accent color and keyboard-focus behavior.
Accessibility validation and guidance
tests/unit/*, tests/e2e/user-journeys.spec.js, AGENTS.md, README.md
Tests validate report structure, HTML5 attributes, CSS contrast, target sizes, focus visibility, and page titles. Project guidance documents these checks and the updated test count.

Inline comments:
In `@assets/refactor-first-report.mustache`:
- Line 162: Wrap the Cycle Map link near the Cycle Map navigation item in
classCycles.largestCycle.hasCycleMap so it renders only when the target exists.
Apply the same template change in assets/refactor-first-report.mustache at lines
162-162 and public/assets/refactor-first-report.mustache at lines 162-162;
update tests/unit/report-template-wcag.test.js at lines 94-106 to cover cycles
without a largest-cycle map and assert that no dead link is rendered.

In `@lib/renderer.js`:
- Line 73: Remove start from FORBID_ATTR in lib/renderer.js so valid ol[start]
attributes survive sanitization. In tests/unit/html5-attributes.test.js, remove
start from OBSOLETE_ATTRIBUTES and add or update coverage verifying ordered-list
numbering is preserved.
- Around line 27-28: Update the link-safety check in the sanitizer hook to
normalize the anchor’s target value by trimming whitespace and comparing
case-insensitively before applying rel="noopener noreferrer". Preserve the
existing behavior for non-anchor elements and targets other than _blank.

In `@README.md`:
- Around line 18-19: Update both accessibility statements in the README to avoid
claiming complete WCAG 2.2 AA conformance; describe the site and reports as
targeting WCAG 2.2 AA or having automated checks for selected WCAG 2.2 AA
requirements.
