gate_a_kernel_drills.py stages the three remaining GATE A kernel
drills (controlled-stop deceleration floor, resume waypoint with the
latch locked, mid-ramp latch unlock) with software witnesses and the
PSU-connector scope point. lid_ir_ambient_baseline.csv is the
fire-watch ambient anchor (600 samples, lid closed, machine idle);
BRINGUP records the baseline statistics and the idle verification of
the emission/fire/HV evidence plumbing.
