No owner exit

What ships, and the accepted design

ckeri no longer offers close; the close the M1 V1 release made by the current keys is recorded on Close your identity checkpoint. The accepted design has no owner exit: no close, no parking and no revival. There is no withdraw. Conviction is the only way a checkpoint ends. Play the checkpoint simulator and the registry simulation.

As an identity owner, Alice keeps her checkpoint alive — bonds, rotations, unfreezing, top-ups — until it is convicted. There is no step that takes her checkpoint off chain, parks it or brings it back.

As a relying party, the treasury sees a checkpoint that is either alive (consumable only when bonded, not poisoned and past the juvenility window W) or convicted. A conviction needs a duplicity proof against the checkpoint's key state. It moves the conviction bond to the convictor and the freeze bond and pool to the refund address, and places the retained output in pending custody. Only the associated Registry fold consumes that request, burns the token and permanently retires the registry key. Registering the same AID again is refused forever: the token is minted once.

What happens to the bonds and pool of an owner who simply stops maintaining a checkpoint is an open economic question. Today they leave a live checkpoint only through rotation premiums, a freeze (the freeze bond, to a hunter) and conviction. Parking was removed because it left unsettled who holds the deposit while parked and how a sponsor is tracked; it may return only with an economic model that settles both.

The close page is the V1 command that ships on preprod. Do not read it as the accepted design.
