Re-run of all programs of this folder, 20 October 2026, from a fresh copy of the folder (outputs written to a
separate new directory; verification_run_B/ run inside its copy). Wall-clock times on one core (nice 10).

Every recorded output was reproduced.

A second complete re-run, by the third verification run from a fresh extraction of the source archive, is recorded
in independent_run_2/rerun_package_log.txt (all outputs reproduced; q7_q8_check.py up to the order of three lines).
