5-level verification pyramid: static→unit→Playwright E2E (homepage-first, 6bp)→AI visual→post-deploy. 8-check quality gate. Multi-agent testing (functional/security/a11y/performance). Playwright v1.56+ AI agents (Planner/Generator/Healer, v1.63 current). WCAG 2.2 AA via axe-core v4.13. Percy+Chromatic visual regression. ADA Title II 2027/2028 deadlines.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 07 — Quality and Verification

Run the 5-level verification pyramid (static→unit→E2E→AI visual→post-deploy) with WCAG 2.2 AA and 8-gate quality enforcement on every change.

## 5-level pyramid (bottom to top)

1. **Static** — TS strict + ESLint + oxlint + Prettier + knip (dead code)
2. **Unit** — Vitest 5 (browser mode default, static test discovery, Playwright-trace links)
3. **Playwright E2E** — homepage-first, 6 viewports × 3 browsers, hermetic, parallel
4. **AI visual** — vision rubric ≥9/10 per route, 6bp screenshots
5. **Post-deploy** — `wrangler tail` clean + console-error-free + axe-clean + Lighthouse green

## 8-check quality gate (every PR)

1. `npm run typecheck` clean (0 errors)
2. `npm run lint` clean (0 errors, 0 warnings)
3. `npm test` (Vitest) green
4. `npm run e2e:prod` green at 6 breakpoints
5. axe-core 0 violations per `_kernel/standards.md#wcag22`
6. Lighthouse Perf ≥90, A11y ≥95, BP ≥95, SEO ≥95 (authoritative: `EMDASH_LIGHTHOUSE_MIN_*` in `~/.claude` env)
7. AI vision QA ≥9/10 per route (authoritative: `EMDASH_AI_VISION_MIN`)
8. Console / CSP / network errors = 0

Any fail = blocker. Fix-forward per `rules/verification-loop.md`.

How to install

The exact contents, by fingerprint
mdr add heymegabyte/claude-skills/quality-and-verification@sha256:3840230d37d6ee79

The line at the top of this page pins the label v2.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
