HistoryRead-Raw with NumValuesPerNode=1 returns an empty page between every value

Gateway AtTime returns AVEVA interpolation unchanged (NULL handling, drift, no Interpolated bit)

Gateway historian: strict lowered ceiling refuses ordinary pages; deep event reads slow (follow-ups from #689–#691 gate)

Items 1 and 2 fixed on master 66a2b0c3 (commits 3c3513ea, de8bc7a1). Live AVEVA gate PASS (2026-10-13). Item 3 stays open, blocked on historiangw#27 (still open), so this issue stays…

HistoryRead returns BadHistoryOperationUnsupported when the historian backend is unreachable (should be a retryable communication status)

2026-10-13 02:12:08 -04:00

Historian value types differ across backends for integer/Boolean nodes (SQL backends Int64, Gateway node type; Gateway Raw Boolean as Double)

Gateway raw: warm reads refuse a tie cluster that fits under the learned ceiling (look-back below a reverse segment or bound lookup)

Gateway AtTime: prior-sample search starts at the requested time, not min(T, now); strict-ceiling stopped-tag end-only reads costly

Gateway raw reads return a stored NULL as value 0 (SQL backends return null)
