nx_nxa_groom_gate.nx -- THE GROOM GATE v3: anatomical invariants on a generated groom asset. WHY (operator 2026-08-26, twice in one day): first a backwards groom shipped because the referee plot inherited the organ's own facing assumption; then a head-covering wrap shipped because 794 permil of synthesized roots sat INSIDE the skull and hair grew out of the volume. Both defects are now BANKED REAL ASSETS and both are teeth here. v2 replaces the v1 facing basis (an extreme-extent nose test, itself refuted: the dense face mesh drags the centroid so the sparse occiput measures the larger extent) with the same basis the groom organ now uses: the estate rig convention ANTERIOR-NEGATIVE = FACE, cross-checked by mesh density, refusing on disagreement. license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
