Clamp-between-cones pad at each tunnel end, last composition step, chamber cases removed, bounds extended (proof and
feature samplers 16/16 clean). Open-ground result looks as intended; but pads pass 8/96 (flatness up to 0.75 m, blend
up to 81 deg), interior air fails 16/16 (839-1,588 solid capsule samples), route audits fail, FI band check fails at
seed 0. Owner asked for one attempt, no tuning.
