//! Process exit codes for every `pitboss` subcommand.
//!
//! The numeric values are part of the supported CLI surface — scripts wrapping
//! pitboss read them. Variants were originally named for the `pitboss grind`
//! exit-code table because grind was the first subcommand to surface a non-zero
//! exit; later subcommands (`pitboss sweep`, future others) reuse the same
//! enum so that exit-code semantics stay coherent across the binary.
//!
//! Variant naming therefore mixes generic codes (`Success`, `Aborted`,
//! `FailedToStart`) with grind-flavored ones (`MixedFailures`,
//! `BudgetExhausted`, `ConsecutiveFailures`, `PrCreationFailed`). Non-grind
//! callers map their failure mode onto the closest semantic match — for
//! example `pitboss sweep` returns `MixedFailures` on a halt because that slot
//! is the canonical "exit 1 / something failed" code.

/// Documented process exit codes for the `pitboss` binary. Mapped to a
/// [`std::process::ExitCode`] via [`ExitCode::into_process`].
