package/DATA-manifest-canvas.md

The manifest of the canvas files, with the caveat the tools print.

What it holds

A description of the canvas inputs. The one passage the tools read is its bold line "A per-community rate is fine; a canvas-wide total is not." mem.py adds that regions overlap and a contested pixel counts for every room that claims it. The rest of its content: not stated in the sources.

Who writes it, and when

The handler supplies it in RUN/INPUT/canvas/; build.sh copies it into package/.

Why it exists

Rule 7 asks that "what the canvas measures is stated wherever a canvas figure appears". mem.py canvas prints the caveat under every room's canvas block, then "rule 7: you may use this; declare where it shaped a reading."
