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).

- AttributesAsync was a stub returning nothing; it now reads NodeClass /
DisplayName / DataType / ValueRank / UserAccessLevel in one request and maps them
through UpstreamAttributeMapping, the same mapping discovery registers with (moved
into the shared .Session leaf; the driver forwards to it). Objects have no value
attributes.
- Certificate auth was refused "in v1". The browse now builds its identity through
OpcUaUserIdentityFactory (shared .Session leaf, the driver forwards to it),
including the secret: resolution of Password / UserCertificatePassword through the
host's ISecretResolver (optional ctor param, DI-injected). Fail-closed: a secret:
ref with no store throws instead of being sent as the literal (the browse used to
send a secret: Password verbatim). The identity is built before any network I/O.
