0.6.0 put the store-path rules in the shared library, but the guard was not
running at the moment that matters here.
CreateBuilder resolves ${secret:} references before the host exists, using a
throwaway ServiceCollection that contains no IHostEnvironment — and it runs the
store migrator, which creates the database. The library resolved the content
root from IHostEnvironment alone, so it could not distinguish "no content root"
from "no host registered" and skipped the under-content-root rule entirely. The
store was created at the rejected path; the boot then failed a moment later when
the real host validated. The leftover empty database with its -wal/-shm siblings
is exactly the artifact that made the 2026-08-09 credential loss read as "the
database is there, it's just empty".
The pin alone does not close this. An app with a correctly configured path shows
no symptom and is still unprotected, because the guard simply is not running when
the store is created. 0.6.1 adds a 4-argument AddZbSecrets overload taking the
content root explicitly, and the call site has to use it. The in-host
registration below needs nothing.
Verified by removing the fix rather than by observing a clean boot — which is how
this survived its first release. With the 3-argument overload the new test fails
by finding a created database at
src/ZB.MOM.WW.MxGateway.Server/probe-secrets-*.db: inside the source tree, since
that is what the content root resolves to under test.
Two things about the test itself, both of which it would have been easy to get
subtly wrong:
It asserts no-file-created before asserting that startup threw. "It threw" is the
weaker claim, and asserting it first masks the stronger one — the run that proved
this defect would have reported "no exception was thrown" and said nothing about
the database sitting in the source tree.
The accepting case asserts the database *is* created, not merely that nothing
threw. A not-null builder is close to a tautology once no exception escaped, and
it would still pass if the pre-host container stopped opening the store at all —
which would also quietly void the rejecting case, since that one can only observe
a file the migration would otherwise have written. The two assertions hold each
other up.
Found by HistorianGateway's adoption, which probed the rejected paths instead of
observing a successful boot.
0.6.0 moves the store-path rules into the shared library — both the rooted check
and the content-root check — with a SecretsOptionsValidator wired into
AddZbSecrets and validated on start, so all four consuming apps get the guard
from one implementation rather than four copies. mxgw therefore adds no local
validator over the Secrets section.
This is a four-minor jump, not a re-pin: mxgw was on 0.2.3 and skips 0.3.0,
0.4.0, 0.4.1, 0.5.0 and 0.5.1 in one step. Verified rather than assumed —
diffing the 0.2.3 and 0.6.0 assemblies shows the added surface is the new path
rules and their plumbing (AddIfNotRooted, AddIfUnderContentRoot,
ComputeDefaultSqlitePath, DefaultSqlitePath, IValidateOptions, IsPathRooted,
GetFullPath) and nothing touching store or delete behaviour. Secrets.Ui is
byte-identical across the range: both assemblies are 39424 bytes and differ only
in the version stamp, because this package family shares one version across
every package even when a release touches only one of them. So the browser gate
run against the /admin/secrets delete modal on 0.2.3 still covers what ships
here.
The library default is LocalApplicationData-derived so the family's
cross-platform apps still boot locally. The gateway keeps its own
CommonApplicationData value, which always wins — see the note on
ApplyDefaultSecretsStorePath for why the difference is deliberate and why
deleting that method as a redundancy would silently move the store.
site.css declared `font-size: 0.82rem` literally on `.btn`. Bootstrap sizes
buttons through `font-size: var(--bs-btn-font-size)`, and `.btn-sm` /
`.btn-group-sm > .btn` do nothing but redefine that variable — so a literal at
equal specificity, loaded after Bootstrap, silently flattened every small button
in the dashboard into a padding-only difference. `btn-sm` was inert app-wide.
The kit now owns the sizing: 0.4.0 shipped the four `--bs-btn-*` overrides in
layout.css, which ThemeHead emits ahead of site.css, so removing the local
literal restores `.btn-sm` without a local copy. 0.4.1 is a pin-only follow-up
(it fixes `.rail-btn-block`, which this app does not use; `theme.css` is
byte-identical and the `.btn` rule is unchanged between the two).
The rest of the local rule is kept deliberately. 0.4.0 upstreamed sizing only,
not `border-radius` / `font-weight` / `white-space`, so deleting the block
wholesale would have dropped three app-specific declarations. `border-radius`
also stays a literal rather than `--bs-btn-border-radius`, because `.btn-sm`
redefines that variable and small buttons would shrink to Bootstrap's radius.
Verified in a browser against the running dashboard: `.btn` 13.6px and `.btn-sm`
12.48px, btn-group seams intact, and `--bs-btn-font-size` now declared in
exactly two sheets (bootstrap.min.css, layout.css) instead of three.
Repo-side half of SEC-36. The appsettings.json plaintext was already discharged
before this branch (HEAD ships the fail-closed ${secret:ldap/mxgateway/bind}
store reference), so the residual leak was the literal value in glauth.md,
docs/GatewayTesting.md, and the historical archreview SEC-06 evidence -- all
scrubbed to <service-account-password> placeholders pointing at the source of
truth scadaproj/infra/glauth/.
- csproj: add <UserSecretsId>mxaccessgw-server</UserSecretsId> (dev channel)
- GatewayOptionsValidator: blank-password message now names both channels
(dev user-secrets, deployed MxGateway__Ldap__ServiceAccountPassword)
- test: assert the message names both channels
- docs: GatewayConfiguration.md (three channels + rotation note), glauth.md
(placeholders + rotation-required + runbook pointer), GatewayTesting.md
- new operator runbook docs/runbooks/SEC-36-ldap-credential-rotation.md
(live rotation + NSSM staging remain operator-pending)
- tracking: SEC-36 -> Done (repo-side) in both registers + change-log
Deviation: kept the ${secret:} reference in appsettings.json rather than
deleting it (spec step 2 assumed the stale plaintext baseline); deleting it
would regress the shipped/documented/tested secret-store channel.
git grep -i for the old value is empty across all tracked files.
Family version-matrix alignment. No behaviour change — mxgw registers no Akka
checks, and 0.2.0's per-entry `data` object is emitted only when a check
publishes some, so its health payloads are byte-identical.
Note: this repo uses inline package pins, NOT central package management (there is
no Directory.Packages.props), so the version lives in the Server csproj.
Verified: Server builds 0 warnings.
Part of scadaproj docs/plans/2026-07-22-overview-dashboard-impl-plan.md Task 2.3.
0.2.3's Secrets.Ui ships ConfirmDeleteModal's own styles under
collision-proof zb-secrets-* class names. This host links no Bootstrap so
it never exhibited the invisible-modal defect, but it takes the fixed
line for parity; also rides over 0.2.1/0.2.2 (Akka-replicator fixes -
inert here, no replicator in use). Tests: 780 pass, 45 fail on macOS both
before and after the bump (NamedPipeServerStream multi-instance is
Windows-only - the fake-worker pipe harness cannot run on this platform);
zero delta from the bump.

The suppression's own comment said 'Remove once an upstream fix ships'. It has:
SQLitePCLRaw.lib.e_sqlite3 2.1.12 patches this advisory within the 2.1.x line, so
the premise that no patched release existed is no longer true.
The Server project already resolved 2.1.12, but only incidentally - transitively via
ZB.MOM.WW.Auth.ApiKeys. An explicit PackageReference makes that floor intentional, so
a change to the Auth dependency graph cannot silently regress to the vulnerable 2.1.11.
Removing the suppression restores auditing for exactly that case.
Verified: forced restore of the NonWindows solution reports no NU1903; build is
0 warnings / 0 errors; test results unchanged from baseline (781 passed, 44 failed -
all 44 pre-existing macOS Unix-domain-socket path-length failures in the fake-worker
harness, identical count before and after).
Version hygiene + picks up the G-8 KEK-rotation surface.
NOT a security fix for this repo. An earlier version of this message claimed it
closed GHSA-2m69-gcr7-jv3q; that was wrong. A/B against the 0.1.2 baseline shows
SQLitePCLRaw.lib.e_sqlite3 already resolved 2.1.12, supplied transitively by the
pre-existing ZB.MOM.WW.Auth.ApiKeys 0.1.5 reference.
Note: src/Directory.Build.props still suppresses GHSA-2m69-gcr7-jv3q on the
now-outdated rationale that no patched e_sqlite3 exists. 2.1.12 is patched and
already resolving, so that suppression looks removable - verify separately.
Auth.ApiKeys 0.1.4 pulled SQLitePCLRaw.lib.e_sqlite3 2.1.11, which carries
high-severity advisory GHSA-2m69-gcr7-jv3q. This gateway was genuinely exposed --
verified 2.1.11 resolving before the bump and 2.1.12 after, with the vulnerability
scan now clean.
Auth 0.1.5 is 0.1.4 plus a transitive pin, so there is no API change here.
Suite unchanged from the documented baseline: 781 pass / 44 pre-existing worker-COM
failures on macOS, none Auth/ApiKey/SQLite related.
Claude-Session: https://claude.ai/code/session_01BL2Vu1ESDQ9SCN4gVKkdts
Bump all four ZB.MOM.WW.Auth.* package refs 0.1.2 -> 0.1.4. The shared
ApiKeyVerifier now rejects any key whose ExpiresUtc is in the past;
existing keys have NULL expiry (never expire), so nothing breaks, and the
auth SQLite DB auto-migrates to schema v3 (nullable expires_utc column) on
first boot. Implement the two IApiKeyAdminStore members added in 0.1.3
(SetScopesAsync/SetEnabledAsync) on the test FakeApiKeyAdminStore.
Build green; no new test failures (the macOS worker-pipe IPC failures are
pre-existing/environmental, identical to the pre-bump baseline).
Add packageSourceMapping entry for ZB.MOM.WW.GalaxyRepository in nuget.config
and add the PackageReference (Version 0.2.0) to the Server csproj. Also set
NuGetAuditMode=direct to suppress the pre-existing NU1903 transitive vulnerability
in SQLitePCLRaw.lib.e_sqlite3 2.1.11 (no upstream fix available yet).
Layout
------
DashboardLayout.razor replaces the inline header nav with a left side rail
modelled on the OtOpcUa admin (Dashboard B). The top bar keeps only the
brand, breadcrumb, and signed-in status pill; navigation moves into a
fixed-width 218px rail with grouped section eyebrows (Overview,
Runtime, Galaxy, Admin) and a Session footer carrying the user name,
role claims, and a Sign-out button. dashboard.css gains the
`.app-shell` flex container, `.side-rail` column, `.rail-eyebrow`,
`.rail-link[.active]`, `.rail-foot`, `.rail-user`, `.rail-roles`, and
`.rail-btn` rules (all driven by the existing theme.css tokens, no new
hard-coded colours).
SignalR (push)
--------------
Adds three hubs under `Dashboard/Hubs/`, all gated by the
`HubClientsPolicy` registered in the previous commit:
* DashboardSnapshotHub (/hubs/snapshot)
Broadcasts the full DashboardSnapshot on every change. Sends the
current snapshot to a new caller in OnConnectedAsync so the first
paint is immediate.
* AlarmsHub (/hubs/alarms)
Connected clients auto-join the `__alarms__` group. Receives
AlarmFeedMessage values (active_alarm / snapshot_complete /
transition) re-broadcast from the gateway's central alarm monitor.
* EventsHub (/hubs/events)
Per-session push surface. Clients call SubscribeSession(sessionId)
to join `session:{id}`. The publisher side is intentionally a
follow-up — the snapshot hub already carries recent-events
rollups; a dedicated MxEvent broadcaster on EventStreamService
will plug into this hub's group convention.
Two BackgroundService publishers wire server-side data sources to the
hubs:
* DashboardSnapshotPublisher subscribes to
`IDashboardSnapshotService.WatchSnapshotsAsync` and forwards every
snapshot to all connected hub clients.
* AlarmsHubPublisher subscribes to `IGatewayAlarmService.StreamAsync`
(no filter) and forwards every AlarmFeedMessage to the
`__alarms__` group, reconnecting with a 5-second backoff if the
stream faults.
Connection + auth plumbing
--------------------------
* `GET /hubs/token` issues a fresh data-protected bearer token
bound to the calling user's identity and roles. Gated by the
cookie-only ViewerPolicy so a Blazor circuit (cookie-authenticated)
can mint a token, but a hub bearer cannot self-bootstrap a new
one.
* DashboardHubConnectionFactory (scoped) is the client-side helper
Razor pages inject. It builds a HubConnection with an
AccessTokenProvider that calls HubTokenService.Issue on every
(re)connect — keeps the connection alive across cookie refresh
boundaries.
Pull → push refactor
--------------------
DashboardPageBase no longer drives its own `WatchSnapshotsAsync`
async-foreach loop. It now:
1. seeds Snapshot synchronously from `IDashboardSnapshotService.GetSnapshot()`
so the first render is non-empty;
2. opens a `DashboardSnapshotHub` connection via the connection
factory;
3. updates Snapshot + triggers StateHasChanged on each
`SnapshotUpdated` push.
The hub connection is best-effort: if SignalR can't start, the
synchronous snapshot seed keeps the UI populated. SignalR's
WithAutomaticReconnect handles the recovery path.
Package
-------
Adds `Microsoft.AspNetCore.SignalR.Client` 10.0.0 to the server csproj
so the in-process Blazor pages can open hub connections back to their
own hosting process.
Verification: 475 server tests (+ 2 new
`DashboardHubsRegistrationTests` that pin the hub negotiate endpoints
and the singleton/scoped DI shape), 275 worker tests (+ 9 dev-rig
skips), 18 integration tests (live MxAccess + LDAP + Galaxy) all pass.

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
