Wow, what a finale puzzle. I felt this puzzle genuinely achieved an excellent balance between being a tournament finale & being an introduction to overlap, which I didn't think was possible until I was hours deep into the puzzle. Thank you for hosting the tournament! And thank you for creating these beautiful puzzles!

Before this puzzle, I was a non-overlapping purist and had never ever touched overlap, but man this puzzle has corrupted me into wanting to use overlap in everything. Come Monday, I thought I couldn't be missing *that* much overlap tech, but decided to check the OG leaderboards just in case. I was flashbanged by an unbelievable amount of blinding stew - Putting an input over disposal and an arm?? Using bonder/debonder + conduit to duplicate atoms? Blasphemy!

This solution stays at 29a for most of the construction, but 2 unfortunate swings near the end takes 3a and 2a respectively. (Especially the 2 hexes in the top left that's only used to store the molecule at the end)
