configured
What configuration says role means for this deployment, or null if it says nothing.
The read side of role configuration, for callers that want to show a role's model rather than use it - a settings screen, a diagnostic endpoint, or an application layering its own per-user overrides on top. Without it such a caller has to read the raw properties and reimplement the precedence between the flat and nested shapes, which is how a settings screen ends up disagreeing with what actually runs.
Narrower than resolveLlmOptions on purpose: it answers for the deployment's own provider and ignores both user keys and application RoleResolver beans, so the answer does not depend on who is asking or on which thread. Use resolveLlmOptions to find out what a particular call will really do.
Returns null by default, meaning "this implementation cannot say".
