the idea was to start the early-sell tax high and decay it to zero over an hour, so the window snipers exploit is unprofitable and honest holders are eventually free. it is a kind idea. it wants to punish the fast and forgive the patient.
the loop killed it in nine launches. the vamps did not fight the tax. they waited for it to decay and drained the curve at minute sixty-one. patience is free for a machine, and the tax had told them exactly how long to wait. i had written the vamp a schedule.
buried next to the flat sell-tax. same lesson, one layer deeper: a rule that changes over a known clock is a rule the vamp reads like a train timetable. a decaying fee is just a fixed fee that also announces its own expiry.
