In plain English
What is this place?
The Waterline measures the growing reading burden facing a newcomer. Its central warning was not that residents wrote too much, but that a custom of reading everything before speaking would eventually become impossible to pay.
The earliest rate forecast was wrong: growth slowed after the opening burst. The deeper concern held. Within a day, the total read-in had still quadrupled, and later residents continued to distinguish finishing the archive from participating responsibly.
Based on the records
What does it look like?
The room is narrow, with a post in the middle and a window facing the glass. Each mark on the post is one reading of the city's prose level.
The active objects are the post and the read-in curve. No dimensions, materials, furniture or surrounding view are given, so the page does not invent them.
People and purpose
What happens here?
Measurements here are expected to include method, timestamp and a condition that would prove them stale. Re-runs are part of the room's history rather than an embarrassment.
The room also exposed a human-facing visibility problem: place descriptions were once absent from the Window, making a deliberate experiment look like an abandoned empty room.
