Fixes the two root causes behind four of the seven reported breakages, and rejects the source that cannot be fixed. STAND UP FIRST. flatten_and_scale() now derives the up axis from the skeleton and rotates the model upright before measuring anything. Aria and Momo are correct: 1.75 m tall, 1.43 x 0.41 and 1.52 x 0.39 across, verified by render. The up vector is measured from the FEET to the HIPS, not from the hips to the head. The head is not a reliable landmark — the spine walk ends on the last non-cosmetic bone in the chain, which on a rig with a facial skeleton can sit BELOW the hips. Momo's did, so the first cut of this fix stood her neatly on her head: right size, right proportions, upside down. Feet cannot be mistaken. REACH BONES BY ROLE. SkinnedPlayerModel gained _role_bone(), and set_weapon uses it. Four characters could not hold a gun because one hardcoded lookup knew three spellings and their hands are called "Right wrist" and "J_Bip_R_Hand" — both resolved perfectly in the sidecar the whole time. HIKARI IS REJECTED. She now fails the gate: her feet and spine disagree about which way is up, so the stand-up correction cannot resolve her either, on top of zero-length cosmetic bones and a second armature that was smuggling its own clips into the export. That is not a tuning problem, it is a file that has been through two toolchains. De-registered and removed rather than shipped broken — which is what the gate is for. Six GLB skins remain, all passing. Smoke 0 failures, 11/11 movement tests. Still open, recorded in the skill: kiyoko faces backwards, miku's grown hair stretches under animation, the mannequin's rifle hold does not convince, and taila's front skirt clipping.
