DiffusalOrderBookExecutor

DiffusalOrderBookExecutor is called by DiffusalOptionsOrderBook during settlement.

It encapsulates match execution logic that was extracted for contract-size and separation-of-concerns reasons.

• collect maker/taker fees (including rebate handling)
• validate post-trade portfolio margin health

Access Model

• executeMatch(...) is restricted to the configured order book contract (onlyOrderBook)
• executor itself must be authorized as operator on dependent contracts
