+//! `ask_memory` in `memoryd` (M5c spec, section 9), against a fake Honcho that answers a chat
+//! with the one recorded from rift at `minimal` (fixture 19): the workspaces named, `own` when
+//! none is, both asked at once; each answer labelled by its workspace, neutralised, on one line
+//! and capped; a chat that hangs, fails or finds no workspace is `unavailable`; an unknown name or
+//! a question holding a secret asks nothing. Do not edit.
