//! The §4.2 trail's corpus fixture (bl-4d81): one trail whose rows spell **all
//! five** [`Standing`](crate::opslog::Standing) words, plus both `failed`
//! answers and three readings of `exit_label`.
//!
//! Its own file rather than six inline literals in [`super`], which is already
//! at §12's pre-split band — and its own seam: every other listing here is a
//! list of independent rows, while these rows only mean anything **together**.
//! `standings` is the producer, exactly as it is in the answer; a hand-built
//! standing beside a hand-built row would be a second authority for the fold
//! the fixture exists to pin.

/// One durable line. `cwd` is shared, because §6's retirement key is

/// rather than inferred from the exit: on a `-2` line it is the whole question
/// — a folded sink means the driver died, and an empty one means it handed off
/// (§4.2, bl-b95e).
