Module contracts 

imp-owned worker and evidence contract types.

These DTOs define the boundary between imp’s mana worker runtime, and future runner surfaces. They used to live in the experimental the earlier experimental contracts crate, but currently only imp consumes them, so they stay local until a real cross-repo/versioned protocol boundary is needed.

Modules

evidence

Shared evidence and artifact reference vocabulary.

runner

Placeholder runner-facing contract modules.

worker

Shared worker-facing contracts.

Structs

ArtifactRef

Reference to a durable artifact without embedding storage-heavy payloads.

EvidenceBundleRef

Reference-first evidence bundle shape; storage stays owned by mana.

VerifierResult

Minimal verifier result lineage shared across imp and mana.

WorkerAssignment

Everything needed to execute a unit as a worker.

WorkerAttempt

A previous attempt on a worker-assigned unit.

WorkerResult

Structured outcome from a worker run.

Enums

ArtifactKind

Narrow first-pass artifact kinds that other runtimes can trust cold.

VerifierStatus

Minimal shared verification status for cross-boundary lineage.

WorkerStatus

Worker completion status.
