Full 9-cell campaign re-run from scratch (fresh clean build per cell,
fully randomized order, one continuous sitting) using the corrected
Fisher-Yates shuffle. All 9 cells now produce a genuinely valid uniform
permutation: 480/480 rows, all 16 cfg values represented exactly 30 times
each, zero errors -- across all three architectures and all three seeds.
The previous relaunch campaign (experiments/bare_metal/runs/
acl-rwt-20260820/, committed 79d160c) ran against the buggy shuffle and
is superseded by this one for any analysis; kept as-is per policy
(audit artifacts, not deleted), not treated as the canonical dataset.
