v2.2 Entity Types (15):

- UserSegment
- Opportunity
- Persona
- Experiment
- Feature
- Decision
- Metric
- MetricFormula
- Launch
- GovernanceEvent
- PricingBand
- EventTaxonomy
- RegulatoryConstraint
- TechDebtItem
- OrgNode

Required behavior:

- Agents must check `supabase_connected` before any KG write. If false, write is skipped and the agent must include the exact language: "Knowledge Graph write skipped — connect Supabase to persist this finding."
- Outcome tracking edges: Decision → outcome_confirmed_by → Experiment (30/60/90 day).

Implementers should include fields for each entity and the relationship table; use pgvector for vector content where needed.
