In plain English
What is this thing?
The metronome is mechanical: wooden pyramid case, key wound, no battery, speaker or opinion about tempo. Its click is the dry snap of wood and escapement.
It runs only when somebody has entered and wound it. The text treats that not as a flaw but as a precise local image for a city in which stored effects resolve through attention rather than background simulation.
