A 2026-08-11 investigation treated the windev production binary as having no
traceable provenance. Both pieces of evidence were normal output of our own
build and deploy procedure, and the binary was fine — but nothing in the repo
said so, so it cost a forensics pass to establish.
The version stamp is the first trap. SHA stamping landed in ec6f82b (TST-11)
and was broken on Windows until 0152180 (NEXT-09) a month later: the trailing
backslash in MSBuildThisFileDirectory escaped the Exec's closing quote, and
because the target runs ContinueOnError with ConsoleToMSBuild, git's stderr was
stamped as the revision. Every Windows build in that window reads
`0.1.2+fatal: cannot change to ...`. The point an operator needs is that this
is non-diagnostic in *both* directions — it neither incriminates a build nor
confirms one — which is not obvious from a stamp that looks like a failure.
The second is that the build directory is *supposed* to be gone: deploys build
from a detached worktree so the host's checkout stays on its own branch, and
remove it afterwards.
Records what does identify a build instead, cheapest first — including the wire
probe for the worker, since plain Write/Write2 carrying statuses[0] separates
53f69cd from b948e69 without host access or symbols — plus the deploys to date.
Also records something that went unlogged and is the reason this read as a
mystery rather than an improvement: the 2026-08-09 deploy returned the x86
worker to mainline. Production had been running dd7ca163, contained only by
origin/test/client-e2e-coverage and not an ancestor of main, so the worker in
production was not rebuildable from any mainline commit.
SEC-25 (near-term hardening; full per-session EventsHub ACL stays deferred to
roadmap item 12): DashboardEventBroadcaster now redacts tag values from a deep
CLONE of the event before mirroring to SignalR when Dashboard:ShowTagValues is
false (the default). Clears MxEvent.value (covers OnDataChange/OnWriteComplete/
OperationComplete/OnBufferedDataChange — their bodies are empty discriminators,
values ride in the top-level field incl. buffered arrays) and the alarm body's
current_value/limit_value. Source event never mutated (shared with the gRPC
path + replay ring) - verified by a source-not-mutated test. Makes the formerly
dead ShowTagValues flag live for the mirror. EventsHub TODO(per-session-acl)
kept and tied to roadmap item 12. Tests: DashboardEventBroadcasterTests (3).
SEC-30: trim docs/Diagnostics.md to mark opt-in command-value logging as NOT
YET IMPLEMENTED (no LogCommandValues knob, RedactCommandValue has no call
sites, no values logged); wiring deferred pending secured-bulk redaction
coverage (SEC-13). No option/call sites added.
Server build clean (0 warnings); Dashboard tests 152/152.

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

- Resolve 14 conflicts from popping local stash on top of origin's
eed1e88 + 8d3352f doc-comment additions (11 mechanical, plus
version.rs, DashboardAuthenticatorTests.cs, DashboardGalaxyProjector.cs)
- Fix 4 test files that used AGENTS.md as the repo-root sentinel
(now use CLAUDE.md, since AGENTS.md was removed in 4731ab5)
- Redirect 10 doc citations from AGENTS.md to the matching gateway.md
sections (Value Model, Status Model, Security, STA Worker Thread
Model, gRPC Layer rule, cancellation rule)
Verified: solution build clean, x86 worker build clean, 266/266
gateway tests passing, 121/121 worker tests passing.
