Ask a school what it is for and you get the manifest functions — the ones printed in the mission statement. Ask what it actually does and you find latent functions nobody planned. Ask what a student learns there and you find the hidden curriculum: lessons taught by the shape of the room rather than by the syllabus. Switch layers to watch the same building get re-labelled, read three ordinary school facts through each layer, then sort twelve claims back where they belong.

Same building, same bell, same children. What changes is the question you bring to them.
