Welcome to min G! No need for debonding, calcification or projection, and dispersion forces 4 track. The need to avoid bad bonds constrains the geometry a LOT - had to rule out diamond-shaped track footprints so the polymer could get to all sides of the triplexer. And so we get a long boi track and lots of juggling. First solve was 1P at 643 instructions, and going 1/2P got me to 489. Still feels like a lot. - mr_puzzel
