Review 2026-10-21 G-4, G-7, G-11, G-10.
- G-4: PerPlatformProbeWatcher publishes its probe handles into the
driver's SubscriptionRegistry under the reserved ProbeSubscriptionId
(-1), so the EventPump's fan-out finally reaches the watcher — every
ScanState event used to be dropped as "stale after unsubscribe" and
per-platform host status never updated. ResubscribeAllAsync delegates
the reserved entry to the watcher's new ResubscribeAsync, so the probe
survives a reconnect; StopAsync removes the entry. Probe traffic is
routed by the reserved handle and never reaches the public OnDataChange.
The watcher is also built on the seam path (subscriber only), which is
what makes the wiring testable without a gateway.
- G-7: GalaxyDiscoverer.DiscoverAsync returns the hierarchy it fetched and
the driver selects its $WinPlatform/$AppEngine probe targets from that
same sweep instead of asking the gateway for the whole galaxy twice.
- G-11: OnPumpDataChange stamps LastSuccessfulRead from inbound stream
data, throttled (1 s default), so the comms-loss watchdog has honest
liveness evidence under a Degraded supervisor.
- G-10: an EventPump dispatch-loop exit that is not a cancellation now
reports a stream fault so the supervisor recreates the pump, instead of
leaving a deaf pump reporting Healthy.

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.
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.
