HistorianGateway answers a per-source ReadEvents (Source_Object = DevWinPlatform) with the object's own events (SourceName DevWinPlatform) AND its attribute alarms, which it reports as <Object>.<Attribute> (Source_ProcessVariable, e.g. DevWinPlatform.CPULoadAvg). The Gateway backend's defensive client-side source filter compared SourceName for equality, so it dropped the attribute alarms: 70 of the 72 DevWinPlatform events on vd03. The filter (and the past-the-cap "more events" signal) now uses EventSourceMatch: the source itself, or <source>.<anything> on the '.' boundary, ordinal. DevWinPlatform never matches DevWinPlatform2 or DevWinPlatform2.X. This needs no wire change and still makes one request. Each event keeps its own SourceName. SourceNode stays the condition its stored alarm id names, which is null for AVEVA rows. The attribute events ride the notifier's own read, so the per-folder HistoryRead verdict (#826) governs them: a denied folder answers BadUserAccessDenied before any backend call. The SqlServer and QuestDB backends still match exactly; they hold only OtOpcUa's own events. Tests: - GatewayAttributeEventSourceTests (16): the boundary theory, attribute-in/sibling-out through the data source, the drain signal, and an exact attribute-named read. - AttributeEventHistoryWireTests (2, over a real SDK session with the production Gateway backend on an AVEVA-shaped deterministic gateway): object + attribute events with their own SourceName, a prefix sibling excluded, paging, and the ACL-on deny with no backend call plus a granted positive control. - Mutation-checked: exact match fails both wire tests; dropping the '.' boundary fails the wire sibling check and 6 unit tests. - Live AVEVA harness re-run against vd03 HistorianGateway ea9f21c (read-only, no WinRM): folder DevWinPlatform 2 -> 72 events (whole, 72 1-event pages, reverse); the new #882 check passes; 221 of 225 shared cases are identical to the #801 SDK2 baseline, and the 4 that differ are exactly the DevWinPlatform event cases. Recorded in aveva-history-801.md. Follow-up #886: production folders name RawPaths/EquipmentIds, not Galaxy objects, plus the AVEVA severity/condition property mapping.
