- FK rules via migration 7884505b16b3 (verified on dev with a rolled-
back probe): transactions/recurring items SET NULL on category delete
(this also fixes the 500 that DELETE /categories raised for in-use
categories), water readings CASCADE with their receipt. Models declare
ondelete to stay in sync. (ARCH-09, BE-11)
- compute_actuals_by_source: 3 grouped queries replace 10 single-
aggregate round-trips; behavior pinned by the existing cycle suite.
(BE-21)
- compute_cc_by_category prefetches category names (ARCH-15); agent
pension latest-per-fund resolved in SQL (BE-04); municipal water
consumption batched into one grouped query (BE-05).
- Deterministic pagination: date DESC, id DESC on all transaction
listings. (ARCH-12)
- New agent-tool tests (session binding, JSON-safe output, batched
queries): 64 tests green.
