kin-model contains the canonical shared types for Kin's semantic repository
substrate.
It defines the graph objects that the public Kin stack uses across the local engine, CLI, daemon, MCP server, projection layer, and supporting crates:
- entities, artifacts, relations, revisions, and retrieval keys
- sessions, intents, locks, traffic reports, and coordination events
- review, work, provenance, verification, and temporal records
- projection, reconciliation, preset, and policy types
This crate is intentionally small and dependency-light. It is the schema and domain boundary for the open local substrate, not the hosted KinLab control plane.
