> When Verify Configuration is run for a Connector configuration step, the
> framework merges request overrides onto the working configuration. Properties
> the user never set, because they already have a default, are absent from both
> and therefore missing from the merged context.
> Framework validation still sees those defaults. Connector
> {{verifyConfigurationStep}} implementations typically re-merge with
> {{createWithOverrides}} and then read {{getProperty(stepName,
> propertyName)}}, which does not apply descriptor defaults. Verify can pass
> property validation and then fail or behave incorrectly because the Connector
> sees {{null}} for a property that should have its default.
> Verify should include applicable descriptor defaults for unset properties
> whose dependencies are satisfied, without overwriting explicit working or
> request values.
