WRK-06: MxStatusProxyConverter caches the four resolved FieldInfo per status
type in a static ConcurrentDictionary (the GetField metadata scan ran 4x per
status per event on the STA path). GetValue+Convert.ToInt32 still run per event
(late-bound RCW). Exceptions byte-identical: missing-field message unchanged
(ResolveField, not cached on throw via GetOrAdd); null-value message unchanged.
WRK-11: MxAccessEventQueue.Enqueue takes ownership of the passed MxEvent -
stamps WorkerSequence/WorkerTimestamp on it in place and enqueues it, no
Clone(). Audited all 3 callers (base/alarm event sinks, provider-mode handler):
each builds a fresh event per Enqueue, none reuse it. MxAccessValueCache.Set now
deep-copies its retained Value/SourceTimestamp/Statuses so the cache snapshot
never aliases the queue-owned (later serialized) event. Net: alarm/other events
clone nothing (was full clone); data-change clones payload-only.
WRK-12: WorkerFrameWriter coalesces the flush across a drained batch - each
frame is written but not flushed individually; one FlushAsync after the batch,
then all written frames complete. Preserves the written+flushed completion
contract; a burst of N events costs 1 flush, not N. On write failure the whole
in-flight batch + queue fail so no caller hangs.
IPC-15 (doc): the multi-event WorkerEnvelope body remains unimplemented (wire
still carries one event per worker_event frame); gateway.md Performance section
now distinguishes the shipped flush-coalescing from that deferred proto change.
net48-safe (no init/records; readonly struct cache entry). Worker builds x86
only - verification on windev. Tests added: converter cache-reuse, queue
ownership-transfer, value-cache snapshot independence, writer batch-flush-once.

Adds missing <summary>/<param> XML docs across 99 server, worker, and test
files so CommentChecker reports zero issues (TreatWarningsAsErrors needs the
analyzer clean). Bundles in WIP dashboard work: NavSection extraction,
MainLayout/site.css/js styling alignment, and DashboardOptions/Auth tweaks.
Apply the ZB.MOM.WW. prefix to all gateway-side projects, folders,
.csproj/.sln contents, C# namespaces, using directives, generated proto
C# (csharp_namespace + checked-in generated files), InternalsVisibleTo
attributes, project-name string literals (LoadProject, .sln lookups,
worker exe paths, staticwebassets manifest), and the install/script/doc
references that point at any of the above. Migrate the solution from
.sln to .slnx via `dotnet sln migrate` and delete the old file.
External-runtime identifiers are intentionally NOT prefixed so external
configuration keeps working:
- GatewayMetrics.cs MeterName ("MxGateway.Server")
- DashboardAuthenticationDefaults Scheme/Policy ("MxGateway.Dashboard")
- GatewayRequestLoggingMiddleware logger category ("MxGateway.Request")
- StaRuntime thread name ("MxGateway.Worker.STA")
- appsettings.json root section "MxGateway" + env-var prefix
MxGateway__... and secret-name MxGateway:ApiKeyPepper
- C:\ProgramData\MxGateway\ data dir paths
Also fixes two tests that were not rename-related but became visible
while validating the rename:
- WorkerLiveMxAccessSmokeTests.ShutDownAsync: cancellation that the
gateway service correctly maps to RpcException(Cancelled) per gRPC
convention was being misclassified as a stream fault. Added a sibling
catch on RpcException with StatusCode.Cancelled.
- IntegrationTestEnvironment.ResolveRepositoryRoot: extracted IsRepositoryRoot
and made it accept either a .git marker OR a .sln/.slnx next to src/
so the worker-exe walker works in non-git working copies.
clients/proto/proto-inputs.json's protoRoot updated to point at
src/ZB.MOM.WW.MxGateway.Contracts/Protos.
Verified by `dotnet build` and a full `dotnet test` of the .slnx with
MXGATEWAY_RUN_LIVE_{MXACCESS,LDAP,GALAXY}_TESTS=1:
Tests: 472/472 pass
Worker.Tests: 280/280 pass (4 dev-rig [Fact(Skip=...)] skipped)
IntegrationTests: 18/18 pass
