#Overview

One instance's serialized protocol KV snapshots on SQLite-backed storage. Storage and host identity never enter the shared application's state.

An expiring snapshot arms the instance's alarm at expiresAt plus alarmGraceMs, and only when expiresAt changes: an alarm write is billed as a row written, and a counter's expiry changes once per window, not once per call. alarm() deletes the storage of an expired snapshot.
