//! Unit coverage for `archive_recovery`. Pure helpers
//! (`split_sha_date`, `id_from_path`, `parse_deletions`) are exercised
//! with crafted input so the recreate/live/header-corruption branches
//! that real git never emits are still covered; the git-touching
//! functions run against a real temp store.
