Control Plane

Settld is the enforcement layer between autonomous actions and settlement.

Layer model

1. Identity and delegation
2. Agent identity, delegation lineage, revocation/expiry checks
3. Policy decision
4. Deterministic outcome: allow, challenge, deny, escalate
5. Execution binding
6. Request binding to policy/authorization context
7. Settlement and lifecycle
8. Authorization, verification, release/refund/reversal paths
9. Evidence and operations
10. Receipt bundles, closepacks, replay, audit exports

Hard invariants

• No paid settlement without verification checks.
• No override without signed operator decision.
• No mutable receipt history (append-only timeline).
• No bypass path around policy runtime for high-risk actions.

Why this matters

Payment rails can settle money. Settld makes agent settlement trustworthy, explainable, and operable under incident pressure.
