| 2 | * Full create→write→read→live-update loop — the "smoke alarm" (sprint plan S0.3). |
| 3 | * |
| 4 | * Exercises the REAL data-plane helpers (not a re-implementation) against a |
| 5 | * live DoltGres, proving the exact path ISY hits: |
| 6 | * |
| 7 | * provision a project database |
| 8 | * → write a row with `SET dolt_transaction_commit = 1` |
| 9 | * → DOLT_HASHOF('HEAD') ADVANCES (this is what the realtime poller |
| 10 | * watches — so a "live update" would actually fire) |
| 11 | * → read the row back |
| 12 | * → drop the database (cleanup) |
| 13 | * |
| 14 | * If any link breaks on DoltGres, it fails HERE instead of in production. |
| 15 | * |
| 16 | * How to run (needs the local DoltGres container up on :5433): |
| 17 | * BRIVEN_DATA_PLANE_URL=postgres://postgres:password@127.0.0.1:5433/postgres \ |
| 18 | * bun test src/db/full-loop.integration.test.ts |
| 19 | * |
| 20 | * Skips entirely when BRIVEN_DATA_PLANE_URL is unset (keeps the no-DB unit run green). |
