Module snapshot 

Atomic four-layer snapshot orchestration.

Snapshotter runs the four LayerCapture implementations concurrently, collects their layer descriptors, assembles a Manifest, persists it via PfStore, and returns the resulting content-id. The whole orchestration is wall-clock ≤500 ms for the synthetic 4-layer fixture (Phase-1 acceptance gate).

Structs

Snapshotter

Atomic four-layer snapshot orchestrator.

Enums

LayerDescriptor

Heterogeneous capture-result shape — one variant per layer kind.

LayerKind

Discriminator for the four layer kinds.

Traits

LayerCapture

One layer’s contribution to a snapshot. Implementations capture their live state, write blobs into the supplied store, and return a typed descriptor suitable for Manifest embedding.
