//go:build ignore

// seed_test_data.go — fills the live DB with the reference + test data the
// current flows need, so Dharaneesh's customer/miler app builds have something
// real to work against.
//
// It seeds: (1) reference states/districts + pricing, (2) the base/hub network
// and tenant locations, (3) TEST MILERS WITH NO PIN so the first-login set-PIN
// flow can be exercised, and (4) a sample customer plus a multi-destination
// customer-app booking with two consignments in the rider's hands (ready to
// test the base-handover fix).
//
// It is IDEMPOTENT and NON-DESTRUCTIVE: every block is create-if-absent by a
// natural key. It never TRUNCATEs, never overwrites a curated live row, and —
// critically — never resets a test miler's Password once set, so re-running it
// after a rider has chosen their PIN does not wipe it.
//
// Run:  go run scratch/seed_test_data.go   (needs .env pointing at the target DB)
