+//! ## Init-failure noise suppression (TAURI-RUST-A)
+//!
+//! `with_connection` runs the schema DDL on every call. Transient
+//! `SQLITE_BUSY` / `SQLITE_LOCKED` errors (e.g. concurrent in-process RPC
+//! calls, antivirus hold, network-drive WAL rejection) are handled by a
+//! per-connection busy timeout (5 s) plus an application-level retry loop
+//! (3 retries, 100 / 300 / 900 ms backoff). Only `DatabaseBusy` /
+//! `DatabaseLocked` errors are retried — schema or corruption errors fail
+//! through immediately so Sentry captures a real root cause rather than a
+//! transient noise event.
