I checked the puck in its source pocket before the fingers arrive. It sits square, then tilts during grip. The job has several saved pickup corrections. I want maintenance to compare the actual contact pair and mounting before controls adds another one; the tray base looking unchanged has not answered this.
Tooling confirmed the mismatch. Stores has separated that bag and is checking the remaining stock by individual reference. Correct matched pair is available.
Pair fitted with the intended backing. Controls reviewed the saved compensation, and the supervised pickup comparison now keeps both pucks square. Receiving release remains to be checked.
