//! **The §6 signals yog derives from its own reads**, and the words they
//! are said in: `refused` (bl-b43b — the latest model call's failure, read off
//! the response tail the §3.5 classifier already opened), `truncated` (bl-ebef
//! — the `length` finish on that same tail) and `flagged`
//! (bl-6f2f — the signal-out verb's ops row). Every other signal is a
//! `refs/litany/*` mark or the inbox listing, which is the seam this file is
//! split from [`super::signals`] on (DESIGN §12).
