Inventory incomplete. The displayed count is a lower bound; missing items do not prove removal.
None recorded in this Passport.
Not observed in this Passport: A2A skills, MCP resources, OpenAPI operations.
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.

Each class compares an observation with the previous atlas observation. Runs of unchanged observations are grouped. Struck values are what the previous observation recorded; inserted values are what this one recorded.
Declared and observed
15 tools declare hints; the AI readings agree with all 11 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.

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.
