VER-002 reverse-fit verification · machine measurement campaign · dry runs (no glass, no heat) · tolerance ⚠ provisional, set on site
Order: MT-A → MT-B → reconcile both → MT-C (near limit) → MT-D → MT-E → MT-F.
Coordinates are in the frame declared above. Predicted values are the model's prediction; your measurements test them.
A head whose Δ exceeds tolerance flags the run — see the diagnostic note at the foot of the sheet before proceeding.
MT-A
Mid-envelope commissioningforming reserve 191 mm
R5000 full-width sag arc — the first run; establishes the frame and the offset-stack baseline.
Load both CSV files; drive the machine to the state (dry — no glass, no heat).
Confirm both central heads (motor 5) sit plumb over their bases — record x for motor 5; it should read 0.
Measure each head's position in the declared frame; record x and y below.
Read the Δ column — any head beyond tolerance flags the run for review before proceeding.
Note reconcile result; if this is MT-A or MT-B, both must reconcile before MT-C.

MT-F
Transition (widest model band)forming reserve 136 mm
GV-3 flip above datum — nominated by VER-002 as the case where the wire-model prediction is least certain. The measurement that settles the transition-region question. If a wire spot-check between blocks is feasible, take it here (OQ-VER002-4).
Load both CSV files; drive the machine to the state (dry — no glass, no heat).

Reading a divergence: all heads off the same direction → frame/datum offset · Δ growing from the centre outward → a constant in the offset stack (569/148/155) · scattered per-motor Δ above uncertainty → the wire model (expected on MT-F) · lower vs upper systematically different → the upper-chain construction. Record the pattern in the run notes.
