DiffusalOrderBookAuth

DiffusalOrderBookAuth is a deployed contract that provides EIP-712 hashing and signer recovery for DiffusalOptionsOrderBook. It underpins the signature-first placement and cancellation flow used by placeOrderSigned(...), batchPlaceOrders(...), cancelOrderSigned(...), batchCancelOrders(...), replaceOrderSigned(...), and batchReplaceOrders(...).

It handles:

• PlaceOrder typed-data hashing
• CancelOrder typed-data hashing
• signer recovery for EIP-712 payloads used by the signed-order and batch entry points

Its address is passed into the order-book constructor during deployment.

Key Functions

recoverPlaceOrderSigner(...)
recoverCancelOrderSigner(...)

These helpers recover the maker address from the exact typed-data payload that the order-book contract validates before registering or cancelling a stored order.
