abstract: >-
  ArcSettle is a USDC settlement rail for Arc, Circle's settlement chain, whose
  every settlement is gated on-chain by a signed proof-of-reserves attestation:
  settled supply provably cannot exceed the USDC reserves that have actually been
  proven, and a redemption does not reopen settlement headroom until a new
  attestation has observed the outflow. A reserve-aware operator agent runs the
  same gate off-chain first, so an autonomous treasury never spends gas on a
  settlement the contract would revert. Milestone 1: the reserve-gate contract and
  the EIP-712 attestation oracle, tested with forge. Arc testnet only.
