404: no page at that address

Nothing is published here. Either the address is wrong, or a page that used to be at it has moved.

Where to look instead

If you are a program

This response is a real 404, not a 200 with an application shell: every path that does not exist says so in the status line. The body is negotiated: ask for text/markdown or send no preference and you get the list above as markdown; ask for application/json, or request any path under /api/ or ending in .json, and you get an error object with a code, a message and a hint. The shape is in /openapi.json.
