Documentation

Atomic point-in-time agent memory snapshots.

Captures a verifiable bundle of:

  • Git-backed memory dir (memdir/) as a git bundle
  • SQLite tables produced by the memory crate: long_term, vector, concepts, compactions
  • Extractor cursor + last dream_run registry row

The bundle is a tar.zst archive sealed with a SHA-256 manifest. An optional age encryption layer is available behind the snapshot-encryption Cargo feature; the manifest itself stays plaintext so integrity can be verified without the identity.

The crate ships:

  • [MemorySnapshotter] — trait every backend implements.
  • [SnapshotRequest] / [RestoreRequest] — call inputs.
  • [SnapshotMeta] / [RestoreReport] / [SnapshotDiff] / [VerifyReport] — public output shapes (also wire-shape for NATS lifecycle events and CLI JSON).
  • [Manifest] — on-disk bundle header.
  • [SnapshotError] — typed error class with stable variants.

See docs/src/ops/memory-snapshot.md for the operator surface.
