# Battery A (boundary scan): 64x10 + 1460 + 4096 (two 2KB fills) + 0.25s + tail 64x10.
# The firmware probe (net_recv(64)) fires ~45+D ms after the fill1 full drain;
# if it lands on a refilled buffer it EATS 64B at pattern offset 2048 of the 4096 block
# (no echo for those bytes). probe_classify.py rebuilds the expected stream using the
# actual eaten count logged on the device serial line "probe: recv64 n=%d".
