120s lamps-on mash on the burned 9600 e0t5 chip: 236/236 presses, 88.0%
analog fill, NAK 0, zero wedges, board counters flat — normal operation
unaffected by the E0-threshold patch. Bonus field data: the keypad
A-9-E chord fired mid-mash and dropped the board into axis test 4
(display 04000000), confirming that button scanning halts in test mode
while ISR-driven serial keeps running — visible in the log as presses
freezing at 236 while analog continued to 1919.
