The ReconnectSupervisor was constructed but its trigger
ReportTransportFailure was never called. When the gateway StreamEvents
stream faulted, EventPump just logged and exited — the supervisor was
never notified, so a transient gateway drop permanently stopped
data-change notifications while GetHealth() still reported Healthy.
EventPump gains an optional onStreamFault callback invoked from its
stream-fault catch block (not on clean shutdown). GalaxyDriver wires it
to ReconnectSupervisor.ReportTransportFailure so a transport drop drives
reopen → replay.
This is the minimal fix for -001; the pump-restart-on-reopen gap remains
tracked as Driver.Galaxy-008. Regression tests cover the callback being
invoked on fault, the end-to-end supervisor reopen/replay, and that a
clean shutdown does not fire it. Driver.Galaxy suite: 206/206 pass.
Resolves code-review finding Driver.Galaxy-001 (Critical).

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.

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
