What it is

  1. 1The Vlada ontology, layer one (who holds and who owns every Medicare, Medicaid and Marketplace instrument, over time), SIGNED by Ben on build v3o (2026-10-28; docs/architecture/ontology-v2/L1-SIGNOFF.md).
  2. 2Permanent IDs; a legal entity is not its brand nor the contract it holds; history is dated events with filings; every fact graded A/B/C with its evidence; two clocks.
  3. 3Built by tools/ontology2/build.py, served by tools/ontology2/serve.py (the view moves only to a signed build).
  4. 4Tools: resolve_entity, describe_entity;
  5. 5API: /v1/entities.
