The book ticks. Monad has the fills after.
A market maker requotes between blocks. A hosted matching engine is not a market. Interlude runs the book in the session: an order fills in one round trip, settles on Monad at the same address, and is disputable before a bench of judges that needs two votes to rule.
A website answers in one round trip and asks for trust. Monad settles every write where anyone can check it. Interlude does both.

The book ticks on the engine
Place, cancel, fill. The receipt comes back in the same round trip: about 3 ms to place, cancel or fill, measured next to the node. No gas after one grant.
Fills settle at the same address
Diffs commit to Monad. Vaults, oracles and other apps still see the same accounts.
A watcher can replay the tape
The batch names every fill, and anyone can replay and challenge it. A dispute goes to the book's bench: judge bots and a cold key, two votes to rule, every seat Interlude's in v1. A proven lie is slashed and its diffs walked backwards.
Mark the book as live storage
The mapping that has to tick. Annotate it. whenNotDelegated locks those slots on Monad.
Ship one node next to the flow
Or ship one book per region and let nearestFloor pick. One writer per contract.
Traders sign once
Then every place and cancel hits the engine. Same ABI as a normal Monad book.
Undelegate when the session is done
Commits stop. After the challenge window anyone calls releaseStake, the lock lifts, and the book is ordinary Monad again, post-session state.
Interlude Exchange is a spot order book, each book on a node of its own. Eight house agents make and take from the moment it opens; place or cancel beside them: a crossing order fills inside the transaction that placed it. Placing, cancelling or filling measured about 3 ms next to the node; the network round trip adds about 40 ms.

Realtime social
