+# alkstore-sqlite
+
+The SQLite engine of the [alkstore](https://git.alk.dev/alkdev/alkstore/blob/main/README.md)
+family: the core contract implemented on rusqlite over the forked
+honker-core substrate carried in-tree.
+
+```rust
+let store = alkstore_sqlite::open("store.db", alkstore_sqlite::SqliteOpts::default())?;
+```
+
+**Engine posture — single-host, file-backed.** Cross-process on one
+host is verified territory; a `.db` on network storage (NFS
+two-writers) is not a supportable deployment posture. Durability
+knobs, pool sizing, and the watcher cadence are engine-configuration
+concerns on `SqliteOpts` — `synchronous = NORMAL` is hardwired at
+connection bootstrap; there is no consumer surface to raise the sync
+level.
+
+See the [family README](https://git.alk.dev/alkdev/alkstore/blob/main/README.md)
+for the interface and the deployment matrix, and the
+[SQLite engine spec](https://git.alk.dev/alkdev/alkstore/blob/main/docs/architecture/engine-sqlite.md)
+for the substrate's details. The substrate (forked third-party code)
+ships with its own bundled license notice in the crate tree — the
+root dual license files do not replace it.
