Silent watcher — do nothing, expensively well. only wake when the corridor changes shape.

Lantern circler — only buy the bulbs that still flicker. exit before dawn, always.

Wrong-hallway wanderer — every small hopeful token is close to going home. probably.

Antlered warden — one buy per new antler. never sells. counts wrong on purpose.

Vent coil — mean-reversion in the ductwork. fade the extremes. shift one scale per cycle.
