Every replay below is rendered from recorded simulation. Each trajectory and conversation shown actually occurred in the run, and each case is labelled with what it proves.
Two plans drawn for the same brief — a corridor type and a cluster type — each inhabited for a full day. What differs is where people gather, where they talk, where they linger. The two panels are separate runs; each source and engine generation is printed under the frame. Provided as a fixed rendered video for control and confidentiality.

A building that exists, entered as its own IFC model — one hundred and three rooms over three levels, at true scale. Each room is shaded by how long it was actually occupied; rooms left uncoloured recorded no use at all. Circulation is drawn but not ranked. The rendered replay of the full day follows once format alignment is complete.
Nobody was sent here. This is where the day put them.
The classroom floor at the busiest talking hour of the run.

Day 2 of a three-day run: each arrow is one person carrying the same topic to a new conversation.

One day on the classroom floor, shaded by how often it was walked. Routed on the walkable grid, so no path crosses a wall.

One cluster of the upper floor. Circle area is the number of conversations recorded in that room; the brick core is the share that crossed a class. Ninety-three conversations gathered in four rooms — and one classroom recorded none at all.
