// See C:\Users\ricar\.claude\plans\logical-yawning-tome.md for the migration
// plan this schema implements (source: UTILITIES.accdb, SEGUROS 16_be.mdb,

// carries legacySource* provenance columns so migrated rows are traceable
// back to their Access original and the ETL can be re-run idempotently.
