4the reply to a call; `Answer` and `Detail`, what is kept of Jev's answer,
5with `note`, `spread` and `line` to print it; `stored`, which reads old
6answers too; `Entry`, `Stats`, `Home`, `FEED` and `MOST`, the feed;
7`Fetch` and `Live`; `Told`, the messages out; `Admin`, `Answered` and
8`reads_only`, the admin door; and `when`.

11kind of client sent it, and whether it is a visit. `COLUMNS` and `values`
12are the shape of the archive's `events` table.
13
14`tests.rs` sends every message through JSON and back (they cross between a
15Worker and an object that may be on different code for a few seconds after
16a deploy) and checks the printed lines.
