Trait DecisionHandler 

pub trait DecisionHandler:
    Send
    + Sync
    + Debug {
    // Required method
    fn handle_decision<'life0, 'life1, 'life2, 'async_trait>(
        &'life0 self,
        ctx: &'life1 TransactionContext,
        decision: &'life2 Decision,
    ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait,
             'life2: 'async_trait;
}

Trait for handling FSM decision points.

When the FSM reaches a state that requires an external decision (e.g., whether to authorize a new transfer), the StandardTransactionProcessor calls the configured DecisionHandler.

Implementations can auto-approve, publish to an event bus, call out to a compliance API, present a UI to a human operator, etc.

Required Methods

fn handle_decision<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 TransactionContext, decision: &'life2 Decision, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called when the FSM produces a Decision.

The handler receives the full TransactionContext (current state, per-agent status) and the Decision describing what needs to be resolved.

Implementations that auto-resolve should return the same Decision back. Implementations that defer to external systems should publish the decision and return it for auditing.
