# ---------- DOMAIN ----------
domain:
  class: MetadataOntology
  category: AISemanticLibraryMetadata
  subject: FlowHash
  purpose:
    - represent deterministic semantic hashes derived from canonical Flow Algebra state
    - preserve hash identity, algorithm, canonical inputs, canonicalisation rules, flow version, ontology context, generation time, verification state, and provenance
    - support semantic integrity checking, version comparison, change detection, reproducibility, caching, synchronisation, and AI consumption
    - distinguish FlowHash from flow identity, file hashes, content checksums, signatures, semantic truth, and factual correctness
    - enable machine-readable verification of canonical semantic state
