Pre-deployment validation only WARNED when a data-sourced attribute had no
connection binding, so an instance with unresolved bindings still passed IsValid
and could deploy. There was also no check that a binding resolves to a connection
that actually exists at the target site.
- ValidationService.Validate gains an opt-in `enforceConnectionBindings` flag
(default false) plus a `siteConnectionNames` set. Default-false keeps the
template DESIGN-TIME path (ManagementActor.HandleValidateTemplate) non-blocking,
since bindings are legitimately set later at instance/deploy time. The DEPLOY
path (FlatteningPipeline) opts in (true) so:
* a data-sourced attribute with no binding is now a deploy-gating Error;
* a binding to a connection that does not exist on the target site is an Error.
Static (non-data-sourced) attributes are never flagged.
- FlatteningPipeline computes the site-connection-names set from the loaded site
data connections (mirroring M2.1's alarmCapableConnectionNames) and threads it in.
- Tests: TemplateEngine.Tests covers design-time warning / deploy-time error /
static-ok / exists-at-site / non-existent-connection. New
FlatteningPipelineConnectionBindingTests proves the deploy path enforces it.
Mark M2.7 + M2.8 completed in the plan task tracker.
- connection-name capable-set comparer kept as StringComparer.Ordinal:
FlatteningService and SemanticValidator use all-ordinal name-keyed
dictionaries throughout; OrdinalIgnoreCase would be inconsistent with
the rest of the binding-resolution path — added comment documenting this
- IsAlarmCapable protocol-match confirmed consistent with DataConnectionFactory
(both OrdinalIgnoreCase); added case-insensitive InlineData variants
(OPCUA, opcua, mxgateway, MXGATEWAY) to lock the contract
- clarified FlatteningPipeline comment: "filters connections by alarm-capable
protocol, then collects their names" (was "maps from the protocol string")
- added DataConnectionLayer/DataConnectionFactory.cs path reference to
AlarmCapableProtocols sync-risk comment
FlatteningPipeline loaded data connections but never passed the alarm-capable
connection set to SemanticValidator, so the native-alarm-source capability check
(built but inert) never ran — a source bound to a non-alarm-capable connection
deployed silently. Compute the capable set (IAlarmSubscribableConnection: OPC UA
+ MxGateway) and thread it through ValidationService to SemanticValidator.
