 ## M19: Developer Experience & Quality
 
-- [ ] **M19.1** — Storybook 8 (stories for all `ui/` components, dark glass canvas, `pnpm storybook`)
-- [ ] **M19.2** — Visual regression tests (Playwright screenshots for key views, fail on > 0.5% pixel diff)
-- [ ] **M19.3** — Bundle size CI gate (`bundlesize`, fail if > 250 KB gzipped, PR comment with diff)
-- [ ] **M19.4** — Comprehensive mock data (20+ items per content type, mock Nostr relay, mock TMDB)
-- [ ] **M19.5** — E2E cross-browser matrix (Chromium + Firefox + WebKit, mobile viewports iPhone 14 + Galaxy S21)
-- [ ] **M19.6** — Proxy integration tests (mock Anthropic API, assert SSE format, tool_use, error codes, disconnect)
-- [ ] **M19.7** — Lighthouse CI (LCP < 3s, CLS < 0.15, scores posted as PR comment, stored in `reports/`)
-- [ ] **M19.8** — Dependency audit (`pnpm audit` + `license-checker`, weekly job, block on critical vulns)
-- [ ] **TEST:M19** — Run full suite: `pnpm test && pnpm test:e2e && pnpm typecheck && pnpm lint`. All must pass.
