Persistence guarantees advertised by a session store implementation.

Hosts inspect these flags before relying on a durability semantics; a missing guarantee means the caller must arrange it above the store. The flags describe what an implementation already proves with its own tests, not aspirations (KRN-6).

Fields

atomic_session_snapshots: bool

A complete SessionSnapshotV1 is committed as one atomic generation.

aggregate_cas: bool

Saving a generation whose identity already exists either replaces it under one compare-and-swap decision or fails without a partial write; concurrent writers never interleave generations.

append_only_event_log: bool

Events are appended once with monotonically increasing sequence and can be replayed after reopen; duplicates fail closed.

lease_fencing: bool

Cross-process writers are fenced by a lease so a stale process cannot overwrite a newer generation after a takeover.

encrypted_at_rest: bool

Persisted bytes are encrypted at rest by the backend itself.

watch: bool

The store can notify watchers of committed generations.

reference_aware_artifact_gc: bool

Artifact garbage collection is reference-aware: content reachable from a retained provenance receipt, review finding, checkpoint, or publication is never removed.
