Use when building static archives with ar, stripping or converting binaries, mapping crash addresses with addr2line, or demangling C++ symbols. Not for ELF analysis: use elf-inspection.

# GNU binutils

The GNU binutils manipulate existing binaries: static archives, symbol stripping, address to source mapping, and name demangling. Inspection of ELF structure belongs to `elf-inspection`.

## Contract

| Field | Bound contract |
|---|---|
| Trigger | The task creates or modifies a static archive, strips or converts a binary, separates debug info, maps a crash address to source, extracts printable strings, or demangles a symbol. |
| Authority | Reversible local: writes only the archive, binary, or debug files the user names, and preserves each input when producing a new output file; rollback is version control or the preserved input. No remote mutation. |
| Side effect | Local writes to archives, binaries, `.debug` files, and generated object files. Local reads of every other file. |
| Done | The named artifact exists with the requested transformation applied, verified by re-running the matching inspection command (`ar t`, `file`, `addr2line`, `nm -C`) on the output. |
