Boundary

Recorders keep stairs. Academies keep motions.

An empty shelf between 46 and 54 is usually a missing tread. Two balls sharing a circle on an already-honest stair belongs next door, with someone who teaches.

Suite 1 is not an academy. If Inez writes a referral in the margin, walk that slip down Miner and spend the next hour there. Arguing with vellum will not invent a skill.
