Exact states and meaning

ARD
failed
Exact state: unreachable · No document retrieved
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
A2A

Exact state: invalid · Revision 1.0 · 0 skills
InterfaceDelta retained the machine state “invalid” without assigning an additional meaning.

Exact state: not detected · 0 declarative form tools · experimental
No named declarative WebMCP form tools were observed in the origin root HTML.

The atlas shows each capability by its plain identifier, inputs and declared sign-in. Publisher descriptions, paths, links and source evidence are not published here.

The comparison with the previous observation is shown only to the account that recorded it.

Snapshot generated: 14 Nov 2026, 08:50 UTC

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
