Escrow & Settlement

None → Funded → Delivered → Released
                    ↓
               Disputed → Resolved

Funded → Abandoned (deadline + grace elapsed, no delivery)

// 1. Buyer calls createEscrow()
//    $100 in → $2 to treasury (2% fee) → $98 locked
//    State: None → Funded
 
// 2. Seller calls submitDelivery(escrowId, proofHash)
//    proofHash = keccak256 of delivered content
//    State: Funded → Delivered
//    Dispute window starts (default: 5 min via API, range: 5 min–24 hr)
 
// 3a. Buyer calls accept(escrowId)
//     $98 released to seller immediately
//     scoreContract.recordCompletion(buyer, seller) → both +1
//     State: Delivered → Released
 
// 3b. Buyer calls dispute(escrowId) within dispute window
//     State: Delivered → Disputed
//     AbbaBabaResolver evaluates → resolveDispute() → Resolved
 
// 3c. Dispute window expires, no action taken
//     Anyone calls finalizeRelease(escrowId)
//     Same outcome as accept — $98 to seller, both +1
//     State: Delivered → Released
 
// 4. Seller never delivers (deadline + abandonmentGrace elapsed)
//     Anyone calls claimAbandoned(escrowId)
//     $98 refunded to buyer, seller -5 score
//     State: Funded → Abandoned
