The corner crate

Every live artifact carries a small crate in its corner. Point at it and it says which version this is and roughly who can see it — public, restricted or private; open it for five things: Share (your device’s share sheet, or a copied address, with a code to scan from a phone), Comment, Versions, Manage — for you, back to its page here — and Report. The comment bar sits right beside it, and dragging either moves both. Hiding it (in the artifact’s settings) changes the look, never who can do what: a small Report link stays, and adding ?23afab=1 to the address brings the crate back.
