How listing works
Any Mint may post its report to the feed, signed with its own key; the feed verifies the signature under the Mint's NYM, keeps the bytes it signed, and anyone can read them at /mints/<nym>/status. Appearing on this page needs the map: a record signed by a Mint the feed's operator names, listing Mints by NYM, name and domain. For the pilot that is the lab's Mint and one file. When Mints reconcile the map among themselves (the paper's Appendix A.5), the reconciled map takes its place and the operator's list goes away. A Mint that has posted and is not listed is counted above, not shown.
The feed is a small Cloudflare Worker in the site repository under worker/; its README describes the routes, the signed records and how another operator runs their own. The Lab status draws the default Mint's report and checks its signature in your browser; the Steward's book reads the same report.
