Gateway reverse raw paging reads ~32k rows per page on busy tags (ReverseRawReader sizing)

Fixed on master 15ccd9b7 (merge 88141d6e). The reverse walk moved into ReverseWalk.cs: segments are sized from the page size N (~N+8 target, ≤ 2N+18 per read; MaxTieClusterOverfetch is…

Gateway historian: default MaxTimeWeightedRawRows + 18 exceeds the gateway default ceiling

Fixed on master 1f5d3100. The per-sample aggregate budget is clamped to the gateway default ceiling (1,000,000) when the caller's cap is at or under it; the raw path is deliberately not clamped…

Gateway historian: raw HistoryRead returns AVEVA synthetic boundary row as a stored sample

Fixed on master 1f5d3100 (merge of fix/685-687-688-gateway-mapping).

a3ee917fb4 fix(historian): #687 re-review — a row at/before the Unix epoch is never a stored sample

8114f13a28 fix(historian): #687 review — one bounded re-read instead of failing, raw budget unclamped, exclusive forward end
