High-Speed PCIe PCB Integrity Review

I have a multi-lane PCIe board laid out in KiCad and I want a sharp set of eyes on its signal integrity before we order production units. The schematic and layout are finished, so the assignment is strictly a design review with testing; no new routing or simulation work is required...
