"""Real-DB integration tests for BAT-016 ledger consolidation (REQ-036/037).
These exercise `insert_ledger_trade` against an actual PostgreSQL/TimescaleDB
instance (docker-compose.local-test). The mock-based suite cannot catch DB-level
defects such as the hypertable `ON CONFLICT` regression that BAT-016 originally
shipped; this module closes that gap.
Skipped automatically when the local DB is unreachable.
