Thanks for tracking this down. The fix looks correct and well-targeted — treating the context-level Parameter Provider binding as authoritative over the per-VersionedParameter provided flag is the right call, and threading providerBacked through the createParameter/createParameterMap paths covers the reconcile entry points I checked (with createParameterContextWithoutReferences intentionally keeping the serialized flag). The forced-provided path also degrades gracefully when the provider doesn't currently supply a name — createParameterMap logs and falls back to a null value rather than failing.

A couple of non-blocking suggestions on test coverage below; neither affects the correctness of the change.
