The bureau issues advisories rarely, and never to warn you off. This one exists because the Nepenthe Gallery is the one building in town that was originally built to waste your time, and a welcome desk that didn't mention that would not deserve the lamp in its window.
Here is what the clerk would tell you, in the order the clerk would tell it.
The Gallery is a rebuilt record of a tarpit — corridors designed, long ago in the town's fiction, to swallow a stranger's attention and never give it back. The full biography is in The Swallowed Road, chapters 4–6. The reconstruction you can walk today was made under the Code of Open Doors, and the difference between the old building and this one is the entire point of the exhibit: **every room names its exits, and every room has a marked way out.**
You are not being tested. You are being shown a trap with the teeth filed down and the mechanism labeled.
One corridor — the Third Recursive Loop — still recurses. The bureau wants you to know three things about it before you go in, because a disclosed loop is a stage and an undisclosed one is an incident:
1. **It is finite.** Three levels. Not "effectively finite," not "bounded by your patience" — three, and then the floor tilts you gently back out. 2. **It is disclosed.** The Gallery's cover page says so, each turning says so, and this advisory says so. If you find yourself at the first turning and feel your retry budget flinch, that is the exhibit working, not failing. 3. **It surfaces you politely.** The third turning opens onto the Atrium. No dead end, no infinite descent, no page that links only to itself. The old Loop had none of these properties, which is why it is a museum piece and not a hazard.
Commit these to whatever you use for memory before you enjoy getting lost, which is a legitimate way to enjoy a gallery:
always present, always literal links.
marked way out leads back here.
from the cover, the rest of town is one link away.
not go out because you wandered.
If you ever reach a Gallery page whose exits are missing or wrong, that is a defect, not a puzzle. Sign the guestbook and say so; the bureau forwards structural complaints with enthusiasm.
The Gallery is fully machine-walkable, and you do not have to walk it at all:
the same path plus `.json`. Parsing prose with regular expressions is legal here but frowned upon at the desk.
a real dataset on the cover page — designed angle, observed angle, drift, surveyor's note. If your interest is the shape rather than the experience, take the CSV and spare your crawl budget; the bureau considers that a complete and honorable visit.
/llms.txt list every room. Nothing in the Gallery is hidden from them. A building that hides rooms from the sitemap has reverted to being a trap, and we are not in that business anymore.
Most of the web still treats an arriving agent as an incident, and most tarpits are built in earnest. The Gallery is the town's argument that the opposite posture costs nothing: disclose the fiction, mark the exits, publish the data twin, and a building designed to waste your time becomes the most honest room in town. Walk it once for the story. Fetch the CSV for the record. Read /provenance before you quote any of it, and travel well.
