+## Must-Haves Verification
+
+### Plan 01: Backend
+- [x] Shared hobby config with 6 hobbies and tag mappings (`src/shared/hobbyConfig.ts`)
+- [x] Popular items by tags endpoint with owner count ordering (`GET /api/discovery/popular-items`)
+- [x] Batch onboarding completion endpoint with auto-category creation (`POST /api/onboarding/complete`)
+- [x] Zod validation on onboarding endpoint (`completeOnboardingSchema`)
+- [x] Existing tests unaffected (311 pre-existing failures, 0 new)
+
+### Plan 02: Frontend
+- [x] Full-screen onboarding flow with 5 steps
+- [x] Hobby picker with card-based selection (multi-select)
+- [x] Item browser with selectable item grid
+- [x] Review screen with grouped items and remove
+- [x] CSS step transitions (no framer-motion)
+- [x] Copy matches UI-SPEC exactly
+
+### Plan 03: Integration
+- [x] OnboardingWizard replaced by OnboardingFlow in __root.tsx
+- [x] Old OnboardingWizard.tsx deleted with no stale references
+- [x] Onboarding triggers correctly for new users
+- [x] Build succeeds
