- AlarmTransitionKind.ActiveAcknowledged (appended): active AND acked applied as ONE projection.
Galaxy ActiveAcked snapshot entries and OpcUaClient inactive->(active,acked) use it; the
projector writes 'Activated' only if not already active, 'Acknowledged' only if not acked.
- AlarmEventArgs.IsRestatement (optional, default false): set only by Galaxy snapshot entries
and OpcUaClient first sight. A flagged Retrigger on an Active+unacked condition with the same
message and severity, or a flagged Clear on an inactive condition, writes no /alerts row.
- NativeAlarmProjector reports the history rows per transition; ForwardNativeAlarm writes one
row per entry. Unflagged sources (FOCAS/MTConnect/AbCip, live Galaxy) are unchanged.
- Tests: projector rules each with a must-write control; OpcUaClient transition table;
Galaxy feed/driver mapping; Galaxy + OpcUaClient end-to-end through DriverHostActor.

MAJOR-1: a deploy that changes a driver's config respawns it, and the fresh instance's empty told
record re-sent Raise for every still-active alarm, un-acking acknowledged conditions and writing a
duplicate "Activated" alerts row. NativeAlarmProjector now treats Raise on an already-active
condition as a re-statement (keeps Acked; ForwardNativeAlarm skips the alerts row); only Retrigger
(or inactive->active) un-acks. Sources whose upstream ack state is authoritative send Retrigger for
an unacked re-statement: OpcUaClient on first sight (no prior told), Galaxy for an unacked active
snapshot entry. Runtime E2E drives a FRESH FOCAS driver after a redeploy and asserts the ack survives.
MAJOR-2: a failed FOCAS alarm read annotates each subscribed condition BadNoCommunication once per
outage (#626 quality-only path) with one Warning (MINOR-6), lifted to Good on recovery; failed alarm
reads degrade driver health with LastSuccessfulRead frozen (successful ones advance it), so an
alarm-only driver trips the #527 comms-loss watchdog.
MINOR-3 CLAUDE.md #630 bullet; MINOR-4 split line; MINOR-5 a non-empty cnc_rdalmmsg2 payload that
fits neither stride throws; MINOR-7 value-tag + parsed-address tables are built and swapped, never
cleared in place under the retained poll engine. Docs corrected (FOCAS.md, AlarmTracking.md, CLAUDE.md).

Imports the freshly-rebuilt ZB.MOM.WW.MxGateway.Client + ZB.MOM.WW.MxGateway.Contracts
nupkgs (0.1.0) from /tmp/mxgw-dist. Replaces the vendored libs/ DLLs and the
pre-restructure MxGateway.* namespaces across the runtime Galaxy driver,
Galaxy.Browser, and their tests.
Key changes:
- nuget-packages/ added as a local feed via NuGet.config; .gitignore exempts it
from the *.nupkg rule so the packages are tracked
- Directory.Packages.props pins both packages at 0.1.0
- 4 csprojs swap <Reference HintPath="libs/...dll"/> for <PackageReference/>
- 36 .cs files renamed `using MxGateway.*` -> `using ZB.MOM.WW.MxGateway.*`
- libs/ removed (vendored DLLs + README.md)
GalaxyBrowseSession rewritten around the new lazy API:
- RootAsync calls GalaxyRepositoryClient.BrowseAsync (returns LazyBrowseNodes)
and caches them by TagName instead of bulk-fetching the whole hierarchy
- ExpandAsync looks up the cached LazyBrowseNode and calls its ExpandAsync,
giving true one-wire-call-per-click instead of in-memory parent/child scan
- _byGobjectId + _hasChildrenSet dropped (LazyBrowseNode carries HasChildrenHint)
- AttributesAsync unchanged (already uses DiscoverHierarchyAsync MaxDepth=0)
Tests: Galaxy.Tests 245/245, Galaxy.Browser.Tests 10/10, AdminUI.Tests 66/66.
Pre-existing 12 solution errors unchanged (test sinks + Cli XML comments).
Adds <summary>, <param>, <typeparam>, and <inheritdoc/> tags to public
members surfaced by commentchecker — resolves 5,847 of 5,869 issues
(99.6%) across three /fixdocs passes.
The mxaccessgw updated alarms to a session-less central monitor:
AcknowledgeAlarm dropped SessionId and alarm transitions now come from
the session-less StreamAlarms feed instead of the per-session worker
StreamEvents stream. The GalaxyDriver no longer compiled against the
updated client.
- GatewayGalaxyAlarmAcknowledger: session-less rewrite — no GalaxyMxSession;
outcome read from ProtocolStatus (throw) and Hresult (warn).
- New IGalaxyAlarmFeed seam + GatewayGalaxyAlarmFeed: background consumer
of StreamAlarms that decodes the active-alarm snapshot plus live
transitions into GalaxyAlarmTransition and reopens the stream on
transport faults.
- EventPump: drop the dead per-session OnAlarmTransition path; the
per-session stream no longer carries alarms.
- GalaxyDriver: bridge the feed onto IAlarmSource.OnAlarmEvent; the feed
starts on SubscribeAlarmsAsync, independent of data subscriptions.
- Tests: replace EventPumpAlarmTests with GatewayGalaxyAlarmFeedTests;
move the driver alarm-source tests onto the IGalaxyAlarmFeed seam.
Browse needed no change — GatewayGalaxyHierarchySource consumes the
unchanged DiscoverHierarchy contract.
