User decision: save, Test Connect, live browse and the deploy gate keep
refusing out-of-namespace credential references, but an ALREADY-DEPLOYED
driver must not fault at the upgrade restart or (Galaxy) at the next
gateway reconnect, since ReopenAsync re-resolves Gateway.ApiKeySecretRef.
- LegacyCredentialReferenceTracker (Core.Abstractions): the one, deprecated,
call-site-chosen compatibility path. Running Galaxy (InitializeAsync,
ReopenAsync, ack fallback) and OpcUaClient (session open) pass it and keep
the pre-#815 semantics (case-insensitive prefixes, Galaxy file:, OpcUaClient
literal pass-through) with a rate-limited Warning (driver/field/allowed
form, never the value) and a credential-compat:<field> diagnostics entry
(both drivers now implement IDriverDiagnostics). Browsers and probes pass
none and stay hard-fail; Heidenhain has none.
- Deploy-gate message names the migration.
- Upgrade preflight: CredentialReferencePreflightService (admin nodes, once
after ApplicationStarted, ConfigDb only, resolves nothing) logs a Warning
per Draft row / Deployed-artifact finding; the /raw banner shows them plus
Running drivers reporting warn-only use (driver-health diagnostics).
- docs/security.md: exact replacement table (incl. the old form default
env:MX_API_KEY, file:, un-namespaced secret:, casing changes), the
ReopenAsync reconnect behaviour, the warn-only window and its removal.

A Designer could point a Galaxy / OpcUaClient endpoint at a host they control,
set a credential field to any reference the node can resolve
(env:ConnectionStrings__ConfigDb, env:ServerHistorian__ApiKey, secret:<any>,
Galaxy file:<any path>) and click Test Connect / live browse; the node resolved
the value and sent it to that host.
One shared rule in Core.Abstractions (CredentialReferences +
DriverCredentialPolicy) generalises the #803 Heidenhain namespace:
- Galaxy: secret:galaxy/... | secret:otopcua/galaxy/... | env:OTOPCUA_GALAXY_... |
legacy env:GALAXY_MXGW_...; file: refused; dev:/literal API key unchanged.
- OpcUaClient: secret:opcuaclient/... | env:OTOPCUA_OPCUACLIENT_...; literals unchanged.
- Heidenhain adopts the shared parser/resolver (namespace unchanged).
Enforced at the AdminUI save path (DriverConfigSaveGate), the deploy gate
(CredentialReferenceDeployChecks, code CredentialReferenceOutOfScope), Test
Connect (AdminOperationsActor, before any probe), live browse
(BrowserSessionService, before any browser) and again at resolve time in every
driver/browser (fail closed, before any store/env read).
