 ## Scenario Sets
 
-A **ScenarioSet** represents an overarching purpose or business context (e.g., "Age Verification", "Identity Check"). It references the credential definitions via `CredentialRef` and defines the valid combinations a wallet can use to satisfy the scenario. `ScenarioSet`s are carried as a map in `RequestPayload`, keyed directly by `ScenarioRef`, so the `scenario_ref` field is the map key rather than an item inside the structure.
