Spent too long handwaving the swing of middle third, and working on the remote water without that constraint made me overestimate how hard min C is (to the point when Morraconda said "lexC for this puzzle seems to be the same as C?
" on Thursday I assumed they didn't know that minC is possible).

Costwise the tribonder for middle third looks suspect but arm 10 and 12 feeding it are doing good work (need to move fast and get out of way for arm 4/5 big swing). I didn't imagine I can reuse a debonder. Remote water routing takes lot of mechanisms but direct access is blocked by output glyph and what can you do about that.
