pysqlite's legacy mode emitted BEGIN only at the first DML, so every read before it ran outside any transaction and a lock wait surfaced as "database is locked" at an arbitrary later statement; place_bet also mistook that error for a write-snapshot conflict, which SQLite cannot produce. - _register_sqlite_pragmas: synchronous=FULL, isolation_level=None and a `begin` event that emits BEGIN / BEGIN IMMEDIATE. - begin_immediate(session): takes the write lock before the first read; called first thing in place_bet, request_withdrawal, the scheduler transitions, _trigger_payout, the confirmation poller, the reconciler, bump_fee's persist phase, deposit crediting / external-spend marking / reinstating, and the derivation-index allocation at registration. - A lock not granted before a broadcast answers service_busy (503, all seven languages), nothing built or sent; after a broadcast nothing is undone, the rows stay `building` for the reconciler. - Spec, storico, BUGS.md and CLAUDE.md updated; 37 new tests on a real file DB.
