Task 4 of the LocalDb Phase 1 adoption plan.
OperationTrackingStore took IOptions<OperationTrackingOptions> and opened its own
SqliteConnection from ConnectionString. It now takes ILocalDb and gets every
connection - writer and the two ad-hoc reader paths - from CreateConnection().
This is not cosmetic. OperationTracking is a RegisterReplicated table, so its
capture triggers call zb_hlc_next(). That UDF is registered per connection by
ILocalDb and by nothing else, so a raw SqliteConnection would fail closed on
every write. Connections from CreateConnection() also arrive already open -
calling Open()/OpenAsync() on one throws - hence the removed OpenAsync calls on
the reader paths.
OperationTrackingOptions.ConnectionString is now vestigial for this store; the
database location is LocalDb:Path. The options class stays (retention settings)
and the config key stays bound for the site config DB.
InitializeSchema is kept but is now always a no-op in the host: onReady runs
while ILocalDb is being constructed, strictly before this constructor can
receive it. It remains so a directly-constructed store (tests, tooling) is
self-sufficient.
Tests: the store fixture moves off mode=memory&cache=shared onto a real ILocalDb
over a temp file. There is no in-memory mode - LocalDbOptions.Path is a
filesystem path - and testing through a raw in-memory connection would no longer
resemble the host. Verifier connections stay raw on purpose: this fixture never
registers the table, so no trigger fires and the UDF is never reached.
Three DI fixtures needed LocalDb:Path added, because resolving
IOperationTrackingStore now forces ILocalDb construction:
SiteCompositionRootTests, SiteAuditWiringTests, and the AuditLog
CombinedTelemetryHarness.
Verified: build 0 warnings; Host 294/294, SiteRuntime 530/530, AuditLog 354/354.

Secrets.Ui components inject the SHARED ZB.MOM.WW.Audit.IAuditWriter seam,
which is deliberately distinct from the repo's own Commons IAuditWriter —
the G-4 adoption mounted the UI without registering it, so component
activation threw and the page 500'd on every render (hidden behind the
login wall; it plausibly never worked).
Fix: CentralSharedSeamAuditWriter forwards the shared seam into the central
direct-write path (ICentralAuditWriter -> dbo.AuditLog) — NOT the site
SQLite chain, which is never resolved on central and has no forwarder
there. Registered in the Central composition root next to the Secrets UI
authorization wiring.
Regression pin: CentralCompositionRootTests resolves the full Secrets.Ui
component injection set (ISecretStore / ISecretCipher / shared
IAuditWriter) out of the REAL Program.cs via WebApplicationFactory, plus a
type check that the seam is the central bridge. Red on the previous
commit; the defect class is invisible until the DI graph is actually
built.
Live-proven on the local docker cluster: /admin/secrets 200 + interactive
(Blazor circuit + working @onclick), and secret.add / secret.delete events
(both outcomes) landed in central dbo.AuditLog via the bridge.
Closes#22

CentralDbTestEnvironment sets five process-wide environment variables, and
Program's AddEnvironmentVariables() reads them at an unpredictable point during
host boot. With xUnit collection parallelization on, one fixture's teardown
could clear a var mid-boot for a sibling. Since the secrets adoption (G-4)
three of those keys are ${secret:...} references that fail closed, turning a
previously benign empty value into a SecretNotFoundException that aborts the
boot — an intermittent CI failure.
Adds a HostBootCollection that serializes every fixture booting a real host
while depending on that shared state, folding in the narrower "ActorSystem"
collection so its members stay serialized with each other as before. Site-role
fixtures stay parallel: they call Configuration.Sources.Clear(), dropping the
env-var provider, so they cannot participate in the race.
CentralDbTestEnvironment now also fails fast if two instances are ever live at
once, making a regression (a fixture added outside the collection) deterministic
rather than intermittent — this is what surfaced the disposed-CTS defect fixed
in the previous commit. Fixture teardown is try/finally so a throwing host
teardown can no longer strand the vars for the rest of the run.
Cost: Host.Tests runs ~2m30s -> ~4m10s; the serialized Central-boot classes are
most of the assembly's parallelism.
Fixes: Gitea #15
Switch the three literal ${SCADABRIDGE_*} placeholders in appsettings.Central.json
to ${secret:} references resolved by the pre-host secrets expander, and update the
_secrets doc note. Fix Host.Tests fixtures that boot the real Program pipeline against
Central config: CentralDbTestEnvironment now also supplies the LDAP service-account
password and JWT signing key as whole-key env overrides (rollback path) so the expander
skips the tokens without a seeded store; the three fixtures that managed env vars
inline now use CentralDbTestEnvironment.
VERIFY-THEN-FIX: the plan-authoring discovery is CONFIRMED. No code anywhere in
src/ registered IOperationTrackingStore in DI, yet AkkaHostedService and
AuditLog SCE both comment that AddSiteRuntime provides it. Every consumer
resolved it via GetService (null-tolerant) and silently ran degraded:
cached-drain scheduler never armed, PullSiteCalls reconciliation seam never
wired, Tracking.Status degraded to audit-only. This is a FUNCTIONAL FIX riding
the hygiene plan: AddSiteRuntime now registers the store (site-only), so
site-local cached-call tracking runs in its intended mode. OperationTrackingOptions
is now bound + eagerly validated in the Host site-options block.
REQ-HOST-3/REQ-HOST-4 require a MachineDataDb connection string for Central nodes.
The shipped docker appsettings (docker/central-node-a/appsettings.Central.json and
central-node-b) already carry the key. Host-008 had removed the fail-fast Require
because MachineDataDb had no consumer yet; this commit reverses that decision so a
misconfigured or missing connection string is caught at startup with a clear error.
Changes:
- DatabaseOptions: add MachineDataDb property with XML doc comment
- StartupValidator: add .Require for ScadaBridge:Database:MachineDataDb inside the
existing Central .When block, immediately after the ConfigurationDb Require
- StartupValidatorTests: rename Central_MissingMachineDataDb_PassesValidation ->
FailsValidation and flip to Assert.Throws; update comment to cite REQ-HOST-3/4,
shipped docker appsettings, and the Host-008 reversal; add MachineDataDb to
ValidCentralConfig() so all other Central tests remain green
- CentralDbTestEnvironment: supply ScadaBridge__Database__MachineDataDb env var
(mirrors ConfigurationDb pattern) so HostStartupTests, HealthCheckTests, and
MetricsEndpointTests pass through the new Require
- CompositionRootTests, AkkaHostedServiceAuditWiringTests, ActorPathTests: set
ScadaBridge__Database__MachineDataDb env var alongside the pepper env var and
clear it in Dispose, matching the existing pepper handling pattern
Build: 0 warnings, 0 errors. dotnet test Host.Tests: 233/233 passed.
Replace dc=scadabridge,dc=local with dc=zb,dc=local in all dev/test LDAP
references — app config, docker test-cluster node configs (docker/ and
docker-env2/), GLAuth fixture, dev tooling, Host.Tests fixtures,
IntegrationTests factory, and operational test_infra docs. OU structure
(ou=SCADA-Admins,ou=users,etc.) preserved throughout. Email domains
(@scadabridge.local), hostnames, and container names are untouched.
Historical plan docs (2026-05-24-second-environment.md,
2026-05-31-folder-repo-rename-scadabridge-design.md) excluded as
point-in-time records. No synthetic dc=example,dc=com placeholders touched.
Commit 1fcc4f5 added a Central-only Require for ScadaBridge:InboundApi:ApiKeyPepper
(>=16 chars) to StartupValidator. That Require fires in Program.cs before WebApplicationFactory
can apply any WithWebHostBuilder config overlays, so it must be satisfied via environment
variables (which ARE in the pre-host AddEnvironmentVariables() pass).
Fix (test-only, no src/ changes):
- CentralDbTestEnvironment: add ScadaBridge__InboundApi__ApiKeyPepper env var (TestPepper
constant, 23 chars) alongside the existing db connection string; restore on Dispose.
Fixes HealthCheckTests, MetricsEndpointTests, and HostStartupTests.CentralRole_StartsWithoutError
which all use CentralDbTestEnvironment.
- CentralActorPathTests.InitializeAsync: set the pepper env var before WebApplicationFactory
is constructed (the class uses IAsyncLifetime directly, not CentralDbTestEnvironment).
- CentralCompositionRootTests ctor + Dispose: same env-var pattern; those tests already had
the pepper in AddInMemoryCollection (DI-layer only, too late for pre-host validation).
- CentralAuditWiringTests ctor + Dispose: same env-var pattern for the same reason.
- StartupValidatorTests.ValidCentralConfig(): add pepper so the unit tests that call
StartupValidator.Validate() directly with a Central config stop failing.
- Add guard tests: Central_MissingApiKeyPepper_FailsValidation,
Central_ShortApiKeyPepper_FailsValidation, Site_ApiKeyPepper_NotRequired — these lock
the production behavior introduced by 1fcc4f5.
