//! The §11 inspector family's wire shapes (bl-6233, REMOTE §9 step 1) — the
//! five surfaces that had no headless spelling at all, so no seat but the
//! window could read a conversation — and the seventh, the conversation seat
//! itself (REMOTE §9.4, bl-1eb0).
//!
//! [`chat`] holds the two whose rows are messages (the transcript and the
//! inbox), [`records`] the three whose rows are machinery (steps, one step's
//! records, the worktree and the spine). Here: the chokepoint drive that proves
//! the query reaches the encoder, over a real workspace on disk.
