UNDERSTANDING — the evidence behind a capability. Every edge that lands on it: the provider, the tag, the exact OpenAPI file, a calibrated confidence, and the QUOTED FRAGMENT OF THE PROVIDER'S OWN CONTRACT that justifies the claim. Only edges at confidence >= 0.7 whose evidence was found verbatim in the source contract are published, so an edge here is checkable rather than asserted. This is what you cite when someone asks "says who?". Understanding plan. Priced B1 (single-entity synthesis) — $0.01 per call under pay-as-you-go; included in Understanding and Influence.
