Crate converge_policy 

converge-policy

Cedar-based policy enforcement as Suggestors for the Converge Engine.

Policy gates participate INSIDE the convergence loop — they evaluate proposals against Cedar policies and write constraints for violations.

Usage

use converge_policy::{PolicyGateSuggestor, PolicyEngine};
use std::sync::Arc;

let engine = PolicyEngine::from_policy_str(EXPENSE_APPROVAL_POLICY)?;
let gate = PolicyGateSuggestor::new(Arc::new(engine));
converge_engine.register_suggestor(gate);

Available Suggestors

• PolicyGateSuggestor — Cedar policy evaluation
• DelegationVerifySuggestor — Ed25519 delegation chain verification
• FlowGateSuggestor — Flow-level authorization gates
