Enum FallbackKind 

pub enum FallbackKind {
    Versioned,
    BasenameOnly,
}

Kind of fallback that matched, returned by find_file_fallback.

Versioned — suffix/prefix stripping changed the basename (Perl FindFile_fallback’s core function). Drivers: 1206.0536 (mysvjour3 → svjour3), astro-ph0005021 (./aaspp4 → ./aaspp).

BasenameOnly — the only change was directory-prefix removal, matching the binding registry by leaf name. This is a Rust-specific extension on top of Perl’s FindFile_fallback that exists because our contrib-binding registry is keyed by basename. Drivers: 2105.02087 (misc/ieeetran → IEEEtran binding); 2405.18387 (assets/equations → equations binding).

Both kinds win unconditionally over local raw .sty/.cls files at the call site (see input_definitions Step 3): the .rs bindings are hand-tuned for the conversion, so a binding match always supersedes a co-located vendored copy. The variant is preserved for diagnostics and potential future policy tweaks.
