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
6 tools declare hints; the AI readings agree with all 0 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
