  # Try exact composite id match first (e.g. "ollama/local")
  exact = registry_instances.find { |inst| inst[:id] == instance_id }
  return exact if exact

  # Fall back to bare instance name, but guard against ambiguity

.instance_health(provider_name, inst_id) ⇒ Object

D14: display health is the per-instance settings hash the provider's discovery actor writes after each registry commit. The registry instance name here is the operator config name — the same settings key. Empty hash when the actor has not committed yet (cold boot).
