MPP Mandate Reconciler — Scope

This node validates draw execution against a pre-authorized MPP envelope. Each draw is checked against the per-cycle cap and cumulative cap. Expiry timestamps are enforced against valid_until. Output includes a draw-set Merkle leaf commitment for chaining to downstream verification nodes. For mandate granting, see ART-36.
