v2-ci / unit-tests (push) Has been cancelled
The #815 warn-only compatibility window is over. A running Galaxy driver (InitializeAsync, every gateway ReopenAsync, the ack fallback password) and a running OpcUaClient driver (session open) now refuse an out-of-namespace credential reference with the same CredentialReferenceException that save, deploy (CredentialReferenceOutOfScope), Test Connect and browse already raise, before any store / environment / file read and before any endpoint is dialled. The one existing scope check (CredentialReferences.Parse/ResolveAsync) is now the only path; nothing new was added. Removed: - LegacyCredentialReferenceTracker (Core.Abstractions), its rate-limited WARN and the credential-compat:<field> diagnostics entry. - The per-driver Legacy* resolve methods and every `legacy` parameter (GalaxySecretRef, GalaxyAckCredentialResolver, OpcUaUserIdentityFactory, OpcUaUserCertificatePaths, OpcUaClientSecretResolution). - IDriverDiagnostics on GalaxyDriver / OpcUaClientDriver (it only carried the tracker's entries). - The tracker also kept a pre-#836 absolute UserCertificatePath loading on a running OpcUaClient driver; that is refused now too. Preflight / banner decision: KEPT, as a hard error. The Running source (driver-health credential-compat entries) and CredentialReferenceBannerModel are gone with the tracker, but the ConfigDb scan still tells an operator something no other surface does: a Deployed finding is now a driver that is not connecting, a Draft finding is a deploy the gate will refuse - named before anyone deploys, e.g. after restoring an old ConfigDb backup or importing a pre-#815 config. It also carries the #835 cross-instance and #836/#850 path checks. CredentialReferencePreflightService now logs one Error per finding (was Warning) with no warn-only wording, and the /raw banner is alert-danger. DEV and QA ConfigDbs hold no Galaxy/OpcUaClient driver (checked 2026-11-13); no production install exists. Tests: GalaxyDriverLegacyCredentialTests replaced by GalaxyDriverCredentialScopeTests; new OpcUaClientDriverCredentialScopeTests; tracker tests in OpcUaClientSecretResolutionTests / OpcUaClientUserCertificatePathTests deleted; AdminUI preflight tests drop the Running/banner-model cases and assert Error level. Against the old code the new refusal tests fail (Galaxy 5/6, OpcUaClient 4/5; the two positive controls pass on both). docs/security.md: the migration table now says running drivers refuse; the warn-only section is replaced by "The compatibility window is over".
