Gateway server-side named-pipe frame path, wire format byte-identical:
- Writer (GWC-08/IPC-13): serialize once into a single ArrayPool-rented buffer
holding the 4-byte LE length prefix + payload, then one WriteAsync. Removes
the second serialization pass (ToByteArray re-ran CalculateSize), the
separate prefix array + second stream write, and per-frame heap allocation.
- Reader (IPC-14): rent the payload buffer from ArrayPool instead of new byte[]
per frame; read/parse bounded to the real length, return in finally. Matches
the worker side which already pools.
- Correctness: length tracked separately from (larger) pool capacity; every
rented buffer returned exactly once in finally incl. the malformed-protobuf
path; ParseFrom copies into the message so the envelope never aliases the
returned buffer.
Cross-checked LE-prefix framing agrees across gateway+worker writer/reader.
Server build clean (0 warnings); WorkerFrameProtocol tests 10/10 incl. a new
large-payload-near-cap round-trip (forces pool buffer > frame). The 2 failing
WorkerClient/FakeWorkerHarness tests are the known macOS UDS 104-char path
limit, not a regression.

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
