TimeAverage2/Total2: the interval the data ends inside with no non-Bad time before its last sample (comms-loss recovery, a single sample) answers that sample's value (Total2 0), Uncertain + Partial, instead of Bad/BadNoData — as the SDK. Parity datasets RecoveryEnds, OutageLast, BoolSwitch with documented masks; ProcessedConformance's reverse TA/Total mask narrowed to the later-edge-sample interval. Docs: report-by-exception consequence, outage-last and Boolean differences; CLAUDE.md historian bullet.
