- IHistorianDataSource.ReadEventsAsync(..., bool reverse, ...) overload: reverse = Part 11 window (lo, hi] newest-first by (time, id) DESC. Default forwards forward reads and throws NotSupportedException for reverse (Null); Gateway refuses explicitly (ascending-only stream). Server answers BadHistoryOperationUnsupported instead of silently returning the earliest N ascending. - SqlServer / QuestDB serve reverse natively (ORDER BY time DESC, id DESC + TOP/LIMIT). - Node manager: reverse event reads page with continuation points; direction stored in the cursor (HistoryContinuationState.Reverse) so a resume continues in the cursor's direction; reverse tie clusters over-fetched forward and sliced from the newest end (SliceTieCluster(reverse:)); end-only reads with a cap page backward from EndTime (mirrors raw). - Resumed event pages over-fetch by the boundary skip, so every non-final page is a full cap page. - Tests: node-manager reverse paging (ties, clusters, coarse resolution, overfetch bound, resume direction both ways, end-only, unsupported backend); shared EventReadConformance on SqlServer + QuestDB; over-the-wire reverse paging; offline Gateway pin of the UTC DateTime.MaxValue bound through the published client's proto conversion (in-process gRPC capture) and FILETIME. - docs/Historian.md event paging section.
