Replaces the handler's whole-pipeline Session (one transaction across all three stages, connection pinned during Ingestion's external IO) with a Unit-of-Work per stage (ADR-0012, added here). Each stage runs its batch in one unit and commits once; any property raising aborts the batch and the subtask fails noisily. - BaselineOrchestrator(unit_of_work, rebaseliner): one unit for the batch, commit once. Raise on a pre-SAP10 property leaves the unit uncommitted. - IngestionOrchestrator(unit_of_work, epc_fetcher, geospatial_repo, solar_fetcher): fetch/write split — phase 1 fetches the whole batch (EPC / coords / solar) with NO unit open; phase 2 writes in one unit and commits. The connection is never held during external IO. Geospatial S3 repo stays injected (reference data, not transactional). - Handler: module-scoped engine (pool reused across warm invocations) + a UoW factory; whole-pipeline `with Session` gone. `build_first_run_pipeline` composes on the factory. Source clients still behind the raising seam. - ADR-0012 records the decision (per-stage boundary, all-or-nothing batch, idempotent re-run, fetch/write split, module-scoped engine). Modelling stub left untouched (no-op, no DB) per the ADR. Tests: orchestrators on a shared FakeUnitOfWork (assert persisted batch + exactly-once commit + no-commit-on-raise). New real-DB E2E integration test: real PostgresUnitOfWork, Ingestion writes the EPC → Baseline reads it back through the repo → re-run replaces, not duplicates (1 EPC row, 1 baseline row after two runs). 121 pass in tests/; pyright strict clean; AAA.
