names: keep state in SQLite

2026-10-16T19:57:19Z

persist() rewrote the whole state file, close to 10 MB, on every settled payment and every queue tick, so one crash during a write could take every name with it. State now lives in SQLite (bun:sqlite, WAL, synchronous=FULL): one row per name, offer, invoice and so on, with the forwarder wallet's state kept as a single row. Each persist() is one transaction that writes only the rows that changed, so a crash leaves the previous state or the new one, never a torn file. The in-memory state object and every persist() call stay as they were. On the first start the JSON state file is imported, and a corrupt one stops startup. The file is left in place, so a rollback to the JSON build still finds its data. store.snapshot() makes a consistent copy while the service runs, for backups. Co-Authored-By: Claude Opus 5.5
