Bernt 754c89506b ADR-011: Four-Layer Data Architecture — Raw Archive → Knowledge → Ontology → Decision
- Layer 1: ArchiveArtifact — immutable original with retention policy
- Layer 2: KnowledgeArtifact — extracted knowledge (observations,
  segmentations, feature vectors, relations)
- Layer 3: Knowledge Graph / Ontology (documented, not implemented)
- Layer 4: Decision Intelligence (existing DecisionCase)
- DataLifecycle: tracks every step with artifact lineage
- Key principle: AI models trained on curated datasets, not whole archive
- Ontology answers 'what does it mean in our domain?'

Long-term goal: Every observation converted once to structured
knowledge, reused infinitely for analysis, decisions, training.
