Nyquist VALIDATION.md scaffold for Phase 2. Defines test infrastructure
(Vitest + Playwright already wired by Phase 1), sampling rates (npm test
after each commit, npm run ci after each wave), Wave-0 dependency surface
(BigQty + scheduler + Zustand store + V1Payload extension), and three
manual-only verifications (AudioContext cross-browser, letter voice review,
cozy-pace playtest). The per-task verification map is intentionally empty —
the planner fills it during plan generation; nyquist_compliant flips to
true once it's complete.
