"""Mako: read-only probe of the interior fork (never saved). The deck well's lip in the Tender's own frame at BOARD (launch
arm, origin (3.015, -3.66, -2.16), turned 90 deg as sweep_check.py does), so the hull can be sized to the user's 1 m limit
before anything is built. Writes checks/well_tender_frame.json."""
