# Level blockout

Ask: beat-sheet | metric-kit | greybox-play.
Block in metrics from `platform-jump` and `locomotion`. One new verb per room (`level-teach`). Art comes after a stranger can walk the greybox (`gameplay-validation`).
Do not dress a room that has no teach/test beat.

Accept: the greybox plays without textures. Jump heights match the kit, not the concept art.
