The TPS25961's exposed pad is GND and the datasheet requires it be connected to the GND plane (Table 5-1; package note 3 adds a mechanical requirement). REVIEW.md claimed this was honoured because the footprint is the _ThermalVias variant -- but the variant alone connects nothing. hardware/TPS25961.kicad_sym defined pins 1-6 only, with no pin for the exposed pad, so KiCad had nothing to map onto footprint pad 7 and left it netless: an isolated copper island under the chip with its thermal vias going nowhere. Adds pin 7 (GND, power_in, hidden, stacked on pin 4) to the symbol library, the cached symbol in exi.kicad_sch, and the U13 instance. PCB updated and verified: U13 pad 7 carries GND on all four elements (both SMD rects and both thermal vias), R48 placed, EFUSE_OVLO routed, R49 gone. DRC reports 0 violations, 0 unconnected pads and 0 schematic parity issues -- the 0-unconnected result is what confirms pad 7 is tied into the GND network rather than merely labelled. The 4 DRC errors previously dismissed as zone-fill phantoms on this pad are gone, though zones were refilled in the same pass so that is not proof of cause either way.
