Verifying changes in accessibility-skills

This is a prompt-only repo — most diffs are docs/skill text with no runtime surface (SKIP those). The exception is committed evidence harnesses under evals/results/<tool>/harness/: each carries a README whose central claim is a reproduction recipe with expected output. Verify those by executing the recipe as a fresh consumer, never by re-running in the directory where the artifacts were authored.

Recipe that works:

1. mktemp -d under the session scratchpad; follow the harness README's commands verbatim, copying any story/test artifacts from the committed repo paths (drift between scratchpad and archive is exactly what this catches).
2. Compare the run's resolved dependency versions against the README's as-run table — report drift even when results hold.
3. Probe beyond the happy path: extract any code snippet quoted in .claude/skills/*/SKILL.md verbatim (sed the fenced block) and run it standalone — doc snippets rot independently of archives. Reproduce any "measured" behavioral claims (e.g., the virtual-screen-reader missing-stop log-leak) in the fresh environment.

Gotchas: the user-level npm guard min-release-age=7 blocks packages younger than 7 days — init tools fail with a message naming the compliant pin; use that pin, never bypass the guard. Playwright Chromium is cached machine-wide (~/Library/Caches/ms-playwright), so browser-mode Vitest runs need no download. Skill mirrors (.claude/skills/ and .agents/skills/) must stay identical — diff the edited sections as part of any verification touching them.
