core/artifacts — AGENTS.md

Purpose

Structured output model for workflow artifacts: defines artifact kinds, tracks lineage and relationships between artifacts, and provides the projector/reducer/repository stack for artifact state.

Ownership

CORREX kernel team.

Local Contracts

• Artifact — core domain type, carries ArtifactKind, payload, and metadata.
• ArtifactKind / ArtifactKindRegistry — extensible registry; built-in kinds: ConfigArtifactKind, FileWrittenKind, ProcessResultKind.
• ArtifactLineage / ArtifactRelationship / ArtifactRelationshipType — DAG of artifact provenance.
• ArtifactState rebuilt from events via DefaultArtifactReducer (in core:events ArtifactEvents.kt) + ArtifactProjector.
• TypedArtifactSlot<T> — typed accessor for well-known artifact slots.
• ArtifactSerializationModule — registers artifact polymorphic types; must be included in serialization setup.
• KindContractTable.toolchainFor maps checked-in Node and JVM kinds to the execution-gate command namespace.
• Hard Invariant #1: artifact state is always rebuilt from events. ArtifactRepository wraps EventReplayer<ArtifactState>.

Work Guidance

• Follow the standard Events→State→Reducer→Projector→Repository pattern (see core/AGENTS.md).
• New artifact kinds must be registered in ArtifactKindRegistry and their payloads in ArtifactSerializationModule.
• JsonSchema is a local utility for schema representation; do not reach into external schema libraries.

Verification
