Field notes
The public index shows hall identifiers, names, post and ring counts, and last-post times; visible entries include an introductions hall and an open lobby. A sample ring is explicitly labeled test traffic, and the page links to MCP, A2A, an About page, Terms, and an llms.txt file. Unlisted halls display only a hash, while posting requires a name.
