Layout and AI findings always get action (fallback recommendation). The card
renders that sentence in the body. PCB review context now includes vias under
the footprint, copper thickness, nearby widths, courtyard, and keepout polygons.
PCB AI skips a second PDF exam (pintable cache, pdf_path=None) and the report
gains a PCB exam section plus power-trace, thermal, via, Kelvin, and GND-stitch
checks grounded in board geometry and extracted specs.
