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

2 tools declare hints; the AI readings agree with all 2 that have a reading.

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

Snapshot generated: 5 Nov 2026, 12:20 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.
