//! **The §3.5 spend ceiling at the frame's own door** (bl-56d5, bl-a80a) —
//! split off [`super`] at the cap on the seam it already had: every other beat
//! there asserts what a gesture *routed to*, and these two assert what one was
//! **refused** by, and that the refusal is a §4.2 trail row rather than a spawn.
//!
//! Two beats because the gate has two claims and the first cannot carry the
//! second: a `0` ceiling refuses over an empty roster too, so only a fire into
//! an idle workspace refused by a *sibling's* spend proves the door enumerates
//! the §3.1 roster at all.
