Its jaws open about 4.5 mm each way along Y and 2.5 mm each way across X. So no contact that carries a wire (any non-GND contact, the e-load's VOUT contact included) may sit within 5.5 mm along Y or 3.3 mm along X of that GND contact. A 4 mm column of contacts with the free GND one in the middle fails, as buck-12v5v's J5 did between J4 and J6. Put the free GND contact where it has that room, before the board is ordered. `adom-aiflow-probing coverage` checks this rule, `collide` checks the whole run, and `redesign` proposes the spot. - **Map by position, not by label.** Older layouts carry older panel labels; one audit found wires two contacts away from where their labels said. Check each MC name against the V2.1.0 PCB's contact positions before writing it.  Write the mapping as a table in the layout's README: molecule contact, net, panel contact, panel group, why.
