#90 is on main. Keep exploring the same Caccetta leftover: next hole is n=109, and F4 is still 0.34640. Close more leftover exact orders past 108 and/or tighten F4 below 0.34640. Same problem folder, same campaign style. When you wrap, open or update a PR with stored DRATs and replay commands. Do not mint a different problem.

Follow-up: continue as q5 on a new branch from origin/main. New work under compute/q5/. New wrap PR, not a reopen of #90.
