Run Pure and aup on an x86_64 WSL2 and an M3 Mac against the Pi (029)

Every pure-run of aup's check (1,053 runs of 667 modules) gives the same
output, errors and exit on the Pi, the WSL2 (x86_64, 4 KiB pages, gcc 13)
and the Mac (Apple clang 21); the same events make byte-identical stores
on the Pi and the Mac, and either opens the other's and goes on the
same. Pure's checks pass one at a time in WSL (each_check.py); its wall
clock is set back about 2 s every 32 s (clock.py). stores.py streams
pure-run's output, whose size grows with the square of the events.
