The parts

There are only three motions to understand. Each motion has a limit. The limit is the product.

Window Share

Two percent of each trade. Holding HAND is free. Sending HAND outside a trade is free. The Window Share does not credit a wallet. Consequence: a Partner never receives the take as cash.

Window Share cannot be rewritten. It has no setter.

Timed Hold

Where every Window Share goes. A Timed Hold is not spendable. It waits on the Gate Rule and a Counter Fill. Consequence: the take is bound the moment the trade lands.

A Timed Hold cannot be unlocked early, redirected, or settled out of turn.

Unbind and the Roll

Unbind turns a Timed Hold into Closed HAND when both conditions hold. Closed HAND leaves issue and is never issued a second time. If either condition fails, the Timed Hold Rolls into the next Live Window untouched. Consequence: Closed HAND only happens when the window and the other side agree.

Nobody can cancel a Roll or claw a Hold back.
