Reference layouts

200 routed boards

22,248 placed parts across 18,839 nets, up to 10copper layers. Every board here is genuinely laid out, not a placement in progress: a closed board outline, footprints inside it, and real copper — tracks or zones — on the board. An unrouted rat's nest teaches the agent nothing, so it does not qualify.
