//! Inject-and-assert test for the viz **Knowledge** tab (plan item C2, LAW #1).
//!
//! The map is the code room's (`Viz.Knowledge`: one bubble per local crate).
//! A workspace nothing was consumed into must SAY so — the reader's
//! `not_consumed`, with its sentence — never a `crates: 0` map that reads as
//! "this workspace has no crates"; and a workspace switch must re-scope it.
//! (The map itself, over a consumed workspace: `viz::knowledge::tests`.)
