//! This file was the drill-in picker's row set until bl-7942: the five JSON
//! records litany contracts to write, the words each seat carries, and the
//! rule that a log earns a seat only when it has bytes. A picker is a face,
//! and the face is the seat crate's now — what a server keeps is the two
//! *names*, which the §7.3 wound and orphan derivations open directly.
//!
//! `pub(crate)` since bl-9b88: the §3.5 classifier reads a step's `stderr.log`
//! too — the out-of-band half of "why the latest model call failed"
//! ([`crate::git_tree`]'s `failure`) — and this module's whole claim is that
//! one file name has one spelling however many derivations open it.
/// The adapter subprocess's captured stderr, per step (litany ARCH §2.3). The
/// §7.3 wound reads its tail to say why a step produced nothing.
