/**
 * ArtifactManifest — canon's SECOND canonical record kind (beside Message).
 *
 * Capability artifacts (skills, agents, MCP configs, plugins) and the intent
 * layer (projects, plans) are versioned document/config BUNDLES, not temporal
 * event streams — they deliberately do NOT use the Message schema
 * (CANON_CROSS_HARNESS_PLAN.md §27p). A manifest records identity, version,
 * blob-addressed content, provenance, and per-harness compatibility; the
 * artifact bytes live in the store's top-level taxonomy dirs and are
 * translated between harnesses by per-kind LAYOUT adapters (skill-dir ↔
 * skill-dir, agent-frontmatter ↔ agent-frontmatter) — never by the gateway
 * Message conversion.
 *
 * plans/projects carry a thin `state` field (doc-snapshot + state — fork 1;
 * NOT a full event log).
