The browser's actual keyboard/search behavior is being tracked separately in [accessibility test issue #65](https://github.com/scarp-lang/scarp-docs/issues/65); static asset checks are not equivalent to a full browser accessibility audit.

 For a local repeat, install dependencies with `npm install`, install Chromium with `npx playwright install chromium` (CI uses the same browser install on GitHub-hosted Ubuntu, which has its required system libraries), run `npm run docs:build && npm run package:offline`, then `npm run test:browser-offline`. Failure screenshots, when possible, are saved under ignored `artifacts/browser-failures/` and uploaded on CI failure. The expanded suite also checks a keyboard-opened empty search state and focus restoration on close (implemented by the small theme-level `local-search-focus.ts` manager for VitePress 1.6), translated-page switching, skip-to-content link and target, persisted appearance mode across reloads, and usable CLI controls under a reduced-motion viewport. These tests exercise selected interactive controls, not every screen-reader combination or a full WCAG conformance audit; track broader access testing in [Issue #65](https://github.com/scarp-lang/scarp-docs/issues/65). The offline distribution remains pinned to the tested docs commit, and the browser suite has no external-search backend.
 
+## Offline accessibility rule audits
+
+The VitePress 1.6.4 search UI needs small theme-level semantic repairs: `search-trigger-accessibility.ts` derives the desktop search control's name from visible text and labels its icon-only mobile form, while `search-dialog-accessibility.ts` presents the overlay as a properly named modal dialog rather than a button containing interactive descendants. Retest these fixes against the real browser whenever VitePress is upgraded.
+
+The offline browser job now runs **axe-core 4.14.0** from the pinned local npm devDependency against ten extracted-site states: English/Hindi Command Finder in light and dark appearances, a narrow 320 CSS-pixel viewport, an open local-search dialog, and the English/Hindi homepages. It asserts zero automated WCAG A/AA violations, verifies that the browser did not make external network requests, and writes per-state JSON results under ignored `artifacts/browser-a11y/` (uploaded to CI on a failure). The 320px viewport checks reflow; it approximates the content width at 200% browser zoom on a 640 CSS-pixel display, **not** a test of native browser zoom or text-only zoom.
+
+The checks run automatically within `npm run test:browser-offline` after `npm run docs:build && npm run package:offline`. If an audit reports a violation, inspect its concrete rule ID, offending selector and remediation in the uploaded JSON rather than excluding the rule. Review `incomplete` manual-review signals as well. These tests catch common machine-detectable accessibility issues but **cannot establish WCAG compliance**, screen-reader compatibility, color differentiation perception, or real-user navigation quality. Manual assistive-technology review remains tracked under [Issue #65](https://github.com/scarp-lang/scarp-docs/issues/65).
+
 ## Supported TypeScript and Vue toolchain
 
 The docs run strict Vue SFC checks through `vue-tsc`. The tested compatibility line is **TypeScript 6.0.x** with **vue-tsc 3.3.x**. TypeScript 7.0 removes the programmatic TypeScript API expected by Vue's checker, causing `ERR_PACKAGE_PATH_NOT_EXPORTED` before actual document diagnostics run. This is an **upstream integration limitation**, not evidence that the TypeScript 7 compiler itself is defective.
