Confirmed with an accelerated bit-packed random-information-set search at rung '1m' (1000000 trials, seed=694493808, pair_depth=16), tightest witness on side X at weight 9. Distance also taken through an internal exact-certification pipeline (MILP, one solve per logical-basis row per side, the same method as this repository's own verify/certify.py). Result: side_status X=exact, Z=exact (solver wall time 173457.5s, CPU time 171220.5s, summed over all per-row MILP solves on both sides). Per CONTRIBUTING.md's confidence-tier policy, this 'exact' claim is self-declared and will display as an upper bound on the board until a maintainer independently re-runs verify/certify.py and confirms it."
