/**
 * Boot migration: reservations.ingest_state.
 *
 * The column gates the two anonymous exports (ICS feed, shared trip) so an
 * automated ingest can park a booking for review without publishing it. Every
 * row that exists before the ALTER has to come out 'live', or the migration
 * would empty a calendar subscription that works today.
 *
 * Ported off the legacy runner (Task 0 triage: PORT) onto the real
 * `Migration20200101031900_reservations_an_automated_ingest_parked_for_review`:
 * migrate to the step immediately before it, seed rows with raw SQL, apply
 * just that one migration, assert. The replay case runs the migration class
 * directly a second time (bypassing the Migrator's own "already applied, skip"
 * bookkeeping) to prove the `addColumnIfMissing` guard is what the legacy
 * test's schema_version rewind was really exercising.
