- LBC supervisor v1..v4 (linux/patches/b10b3-lbc-supervisor-v3.patch + b10/b10b3/lbc-v3-to-v4-fault-clamp.diff): CHARGING 4.20 V/450 mA -> HOLD 4.05 V after 60 min CV -> battery -> new cycle on USB insert; FAULT = VDD_MAX 4.00 V clamp - RAM tests C/B/D/D2/D3/D4 (safety timer only ends fast charge), B10B-4 actuator audit (VDD_MAX works, USB_SUSP does not), B10B-5 FAULT clamp regression, production run, warm reboot via PON reboot reason - cache = B10B-5 c3732515 (HW EDL write, readback + full partition verify), class-A persistent validation - test-only hooks/images are not part of the production kernel; images with the AP PSK are not published
