Conformance over time
What changed across the record, month by month
Covering 2026-08 to 2026-10. Every figure below is computed from the observation record on each publish; none of it is stored, and none of it is written by hand.
88 endpoints, 3 months of record, 71 recorded declaration changes and 7 recorded returns.
2026-10 is covered only as far as 2026-10-03, the most recent observation on the record. Its counts are a part of that month, not all of it.
This report does not say whether grades moved. The observation record retains availability and a capability fingerprint; it has never retained a grade, so no run can look up what an endpoint was graded last month. Deriving one from the fingerprint would be inventing a measurement nobody took. What is reported instead is what the record does hold: who was observed, who answered, and what changed in what they declare.
Month by month
2026-08
45 endpoints were observed at least once this month. 37 answered every check they were given and 8 missed at least one. An endpoint absent from both numbers was not observed at all this month, which is a fact about this project's runs.

Moved from one condition to another
No endpoint that failed to answer moved from one recorded condition to another this month. A month with no move is the ordinary case; a month before this project began retaining the condition can produce no move at all, which is a fact about the record rather than about any endpoint.
2026-09
88 endpoints were observed at least once this month. 63 answered every check they were given and 25 missed at least one. An endpoint absent from both numbers was not observed at all this month, which is a fact about this project's runs.

What a reader should take from this
Nothing here is a trend. A month is a window over one project's probing schedule, and a month with fewer observations is a month with fewer runs, not a month with less availability. The per-endpoint record at the observation record carries every observation with its date, which is the evidence these counts are drawn from.
The narrative front door this report was planned to have is a piece of writing, not a computation, and is deliberately not generated here.
