Enum Decision 

pub enum Decision {
    AuthorizationRequired {
        transaction_id: String,
        pending_agents: Vec<String>,
    },
    PolicySatisfactionRequired {
        transaction_id: String,
        requested_by: String,
    },
    SettlementRequired {
        transaction_id: String,
    },
}

A decision that an external system must make before the FSM can advance.

When the FSM reaches a decision point, it returns one of these variants describing the choices available. The external system (compliance engine, human operator, business rules) must call back with the chosen action.

Variants

AuthorizationRequired

A new transaction was received. The external system must decide how to respond.

Available actions:

• Send Authorize to approve
• Send Reject to deny
• Send UpdatePolicies to request more information
• Send RequestPresentation to request credentials
• Do nothing (wait for more context)

Fields

transaction_id: String

The transaction ID requiring a decision.

pending_agents: Vec<String>

DIDs of agents that need to make a decision.

PolicySatisfactionRequired

Outstanding policies must be satisfied before authorization can proceed. The external system must gather the required data and submit it.

Available actions:

• Send Presentation with requested credentials
• Send ConfirmRelationship to prove agent-party link
• Send Reject if policies cannot be satisfied
• Send Cancel to abort

Fields

transaction_id: String

The transaction ID.

requested_by: String

DID of the party that requested policies.

SettlementRequired

All agents have authorized. The originator must decide whether to execute settlement on-chain and send a Settle message.

Available actions:

• Execute on-chain settlement and send Settle
• Send Cancel if settlement should not proceed

Fields

transaction_id: String

The transaction ID.
