The rework was sound and controlled. The run died because I edited and
deliberately broke the sweep script while its own run was in flight, and the sweep
read the script at its start, which fell in that window.
The self-test refused to run: constructed PERSISTS came back RESETS. Without it the
sweep would have reported RESETS for all three screens -- confident, uniform and
fabricated. First save, on the day it was written.
Three further self-inflicted faults recorded: a competing x11grab during a
measurement (the concurrency confound the port warned of), a pkill -f that can kill
the running sweep's own capture, and a restore that sat as the last line of a
timed-out command so it never ran. The process fix is to commit the tool before
running it.
