## NO BLOCKERS

Reviewed the clean current worktree at **`3d19314537a79c40bacd2e644996e2df711632ea`** on `sprint21/current-import-performance-cockpit`.

- **Schema 51 migration**
  - Legal schema-50 duplicate cash snapshots migrated successfully: schema **51**, both rows preserved, `integrity_check=ok`, **0 FK violations**.
  - Forced mid-migration failure left schema at **50**, restored all pre-migration column sets, leaked **0 tables, 0 indexes, 0 triggers**, and left no open transaction.
  - Removing the synthetic blocker and retrying reached schema **51** with `integrity_check=ok`.

- **Cash snapshot idempotency**
  - Equivalent amounts with different formatting and changed notes produced **1 snapshot total**.
  - First confirmation added one snapshot/audit; replay added **0 rows and 0 audits**, returning the same snapshot and audit identities.
  - Replaying against migrated legacy duplicates retained exactly the original two rows and added **0 audits**.
  - Existing dashboard/idempotency regression also passed.

- **Frontend confirmation paths**
  - Explicit row-confirm UI sent both `category_overrides` and `confirmed_row_tokens` through Apply and final Confirm.
  - The guarded review-only button appeared for technically confirmable but non-business-ready previews, kept economic Confirm disabled, and sent `confirm_review_candidates: true`.
  - Focused Vitest result: **2 passed**; TypeScript typecheck passed.

- **True Wealth repeated activities**
  - Two identical same-day activities produced **2 distinct fingerprints**, stable across reparsing; their persisted activity-ID prefixes were also distinct.
  - Persistence probe stored **2 rows / 2 distinct activity IDs / 2 distinct fingerprints**.
  - A fresh replay was idempotent and left all three counts unchanged.
