Enum SnapshotOrigin 

pub enum SnapshotOrigin {
    Launch,
    ResumeBackfill,
}

The provenance of a Run snapshot’s bound_agents array.

Persisted as the BOUND_AGENTS_ORIGIN_KEY sibling of bound_agents inside the opaque RunRecord::input_json blob. This is Run-store metadata, not a schema-crate Blueprint wire type: it never enters crate::blueprint::BoundAgent, BoundAgentDigestInput, or any digest computation. It lives here beside RunContext — rather than in crate::service::task_launch — because both the domain launch service (which writes it) and the server crate’s bindings-explain handler (which reads it) consume it, and both already depend on this module; parking it in the service module would force the server crate to reach into a service-private type.

Variants

Launch

bound_agents were resolved and pinned at the Run’s initial launch — the binding identity is the launch-time pin.

ResumeBackfill

bound_agents were backfilled from the current Blueprint when a pre-binding-snapshot Run was resumed or reran. The binding identity carries no launch-time pin guarantee.

Implementations

impl SnapshotOrigin

pub fn from_snapshot(snapshot: &Value) -> Self

Read the origin marker from a decoded launch snapshot. An absent (or unparseable) BOUND_AGENTS_ORIGIN_KEY maps to SnapshotOrigin::ResumeBackfill — the safe side: a snapshot whose bound_agents were persisted before this marker existed cannot prove they were pinned at launch, so it must not be reported as a launch pin and (on the replay axis) must not have binding digests mixed into its replay keys. Only test artifacts hit this case in practice — the strict-binding series is unreleased, so no real snapshot predates the marker.
