Current accepted baseline:

- Canonical Entity Catalog v0.4-pre is the active pre-release baseline.
- HUB has an open contour and a managed client/company context.
- `hub.public_pool_client` is a source-backed special Client used by the public pool context.
- `hub.open_contour` must not be treated as an ordinary `hub.client_context`.
- `ops.card` is the canonical OPS work object.
- OPS Product, OPS Gateway, and ENGINE-side OpsLayer are different entities.
- ENGINE L1/L2 workflow split is source-evidenced enough for first resolver implementation.
- Engine-side OPS / Agent Monitor / tender-agent config is non-canonical tech debt.
- Future Interface Layer is a planned separate layer/service, not more custom UI inside ENGINE core.
