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

18 tools declare hints; the AI readings agree with all 17 that have a reading.

A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.

Identity and snapshot

Target key: sha256:95a0e6e25036a105f8fa45b916273f698a13a969ce97117329016f3c92f3cfec
Locator SHA-256: 571fb0ef2dadeec6d82ca5b0ac44876b5a04e1ebef4e1743b294f54c41b973bf
Snapshot generated: 11 Nov 2026, 22:36 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.
