Larger/heavier or repeatedly handled workcell tools favor large pins; document the reason without inventing cycle ratings. Medium pins use the selected LrgMed scaffold’s 8 mm grid and finite span; large pins use the base scaffold’s 32 mm grid. The 2 mm wiring grid is separate. Recheck all sockets, seating and probe-ground compatibility.  Include heatsinks, fans, guards and wires in access/collision checks. Fan rotation does not remove the housing or heatsink from the collision model. If access fails, record a return to interface/placement/routing, implement test points in the native board and revalidate it. Never claim coverage from proposed coordinates alone. Edge connectors need mating/cable clearance after every resize.++## Mandatory mating compatibility gate (2026-10-16)++The workcell probe carries a SHORT MEDIUM machine pin. It can mate only with a verified medium machine contact or an unoccupied medium machine-pin head. A LARGE corner pin or large contact does NOT accept it. Ground continuity, matching XY coordinates and scaffold seating do not prove mating compatibility. Large-pin molecules can mount directly on the base scaffold but still need a separate compatible medium GND receiver for the probe. Do not shrink their mounting pins just to satisfy probing.++Unknown receiver size fails closed. A generic connector/header hole is not a machine contact; do not infer compatibility from drill diameter or a J reference. Explicit machine-part identity is required (a recognized single-pad MC export is supported). Contacts occupied by panel wiring cannot also take the probe. No imaginary adapter, clip, enlarged pin, or socket is allowed.++After changing the board, wiring, receiver or cell tooling, rerun access, plan check, compile, collision, margins and coverage. Compilation must re-read the native board, not trust old access results. If no compatible receiver can reach the tests, record an AIFlow return to DFT/placement/routing for an accessible medium GND contact, rerun native checks, regenerate the twin, and repeat probing. Mark older clips/results invalid rather than retaining a misleading pass. Proposed contacts are design proposals, not installed hardware. Show and record the failed mating and the corrected connection; use separate captions and narrated clips.
