Closes #99. Phase 1 of the uncertainty engine spike. Four endpoints under /api/uncertainty, all gated by requireAuth: - POST /predictions: emits a prediction. Computes cohort_key from surface|model|model_version|bucketLower. Writes state='emitted', orphan_after = now + ttl. Returns id + orphan_after. - PUT /predictions/:id/witness: idempotent. 404 if missing, 409 if already witnessed. Otherwise flips to state='witnessed' with outcome label/correctness/payload and witnessed_at. - GET /calibration?surface&model&model_version: returns the cached snapshot bucket rows for the matching cohort prefix, ordered by bucket lower bound. - GET /orphans: per-surface counts grouped by state. Pure cohort/Brier helpers in api/lib/uncertainty/cohort.ts so they unit-test without needing Hono or D1 in the test surface. Vitest covers bucketing, cohort composition, Brier math, and the schema guards on confidence range and state/outcome enums (18 tests). Mounts in both api/app.ts (AppType source) and pages/api/[...slug].ts (the inlined runtime app, per the existing dual-mount pattern). db/client.ts now wires the uncertainty schema through drizzle.
