Exact states and meaning
- ARDabsent
Exact state: not found · No document retrieved
The supported discovery location returned no matching document.

A usable protocol document was retrieved and validated.
Directly observed
- MCPfailed
Exact state: unreachable · Tool inventory unavailable · resource inventory unavailable · prompt inventory unavailable
The supported discovery location did not provide a usable response within the observation boundary.
An unreachable result does not prove the service is unavailable to every client or that it advertises no capabilities.
Not observed / not fetched
- OpenAPIabsent
Exact state: not detected · 0 operations
No endpoint was established from the evidence and scope that InterfaceDelta inspected.
Not detected does not prove that no endpoint exists.

No tools declare hints.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
