A new identity cannot leave with its stake until an unbonding window has elapsed, and any fraud proof filed inside that window can claw the stake back, so an operator cannot register an identity, take a reward and vanish before the fraud is visible. The cost of one more head is paid in full and is never amortised across the fleet. A farm waits out a pigment, risks an oasis, and holds a signal hostage the entire time: it may abandon the signal to escape, but then the oasis still follows it into the next identity it registers.
