// Round thirty-nine: the faces no walk has seen. Round thirty-one built the
// phone's honest failure states and its own verifier named the gap it left —
// six of them shipped with no expectation at all, because neither `loadHome`
// nor `loadLyrics` was reachable from the `__ss` handle the walk drives the
// app through, and both answer a second ask with nothing (one is gated on
// `started`, the other on the track's own `key`), so no amount of tapping
// re-runs them. Four names on the handle — the two stores and their two
// loaders — eight probe fields, and a block of thirty-six mock steps that
// arms each failure with the mock's own weather, drives the face, asserts the
// words a person reads AND that the Rust string is not among them, and then
// disarms. It lands BEFORE the first-run block: that one reloads twice, and
// the mock's follows live in a module-level `let` a reload empties, so after
// it Home's catalogDown and the Gaps shelf are both unreachable. No new UI,
// no CSS, no Rust, no Kotlin.
