The independent review caught several unsafe issues in the first implementation, so I’m correcting them before closing: overvoltage on U3 EN/UVLO, TPS65987D dead-battery boot strapping, unsuitable TVS selection, and the connector’s 20 Gbps limitation.

Work is paused because no ACUs are currently available, so I could not retrieve or verify the executor’s final correction report.

Completed before the pause: J4 connectivity, a TPS65987D-based PD block, protected ASM VBUS sensing, a 100 × 80 mm board resize, and an independent safety review. Still requiring confirmation are the corrected U3 EN/UVLO network, TPS65987D dead-battery boot, PD-rated TVS, true 40 Gbps J4 replacement, ≥4 A SSD switch, duplicate U10 removal, and M.2 keepout.
