lekss361 b13c4be0ed fix(parcels): SAVEPOINT around velocity compute → не abort outer tx (#154) ... Production POST /parcels/{cad}/analyze падает с 500: sqlalchemy.exc.InternalError: (psycopg.errors.InFailedSqlTransaction) current transaction is aborted, commands ignored until end of transaction block ## Root cause `compute_velocity()` SQL fails (probably на cad's без conkurrentов / sparse sale_graph data) → exception caught в try/except → НО db.rollback() отсутствует → transaction остаётся в aborted state. Следующая query (_geotech_risk на line 828) пытается выполниться → крашится с InFailedSqlTransaction. ## Fix Wrap velocity в `with db.begin_nested()` — SAVEPOINT pattern (consistent with PR #124 pzz_loader fix). Failure внутри savepoint: - Rollbacks ТОЛЬКО savepoint - Outer transaction остаётся clean - Subsequent queries (_geotech_risk и пр.) работают Pattern matches feedback_subagent_delegation audit recommendation для in-loop / per-section exception handling. ## Impact POST /parcels/{cad}/analyze больше не 500 при velocity failure. Возвращает `velocity: null` + остальные fields normal. Refs: user report 2026-05-15 InFailedSqlTransaction Co-authored-by: lekss361 <claudestars@proton.me>		2026-05-15 08:29:24 +03:00
