- POST /import/stage (CSV text), GET /import/status (report + first-50 problem
rows with honest totals), POST /import/commit — all owner-only, audited;
commit still refuses while ANY staged row carries problems (existing guard)
- /import page (ADMIN nav, owner-only): file pickers → problem tables →
verification stats (incl. invoice-value cross-check) → confirm-gated Commit;
re-stage freely, series seeding message surfaced
- 2 route tests (403s for staff; bad→refuse→clean→commit round-trip incl.
series seeding past legacy numbers); suite 344 green
