Acceptance Criteria

1. cargo fuzz --version runs without error

✅ PASS - Command succeeds and reports version 0.13.1

$ cargo fuzz --version
cargo-fuzz 0.13.1

2. Fuzz toolchain is present in rustup show

✅ PASS - Nightly toolchain is installed and active

$ rustup show
Default host: x86_64-unknown-linux-gnu
installed toolchains
--------------------
stable-x86_64-unknown-linux-gnu (default)
nightly-x86_64-unknown-linux-gnu (active)
...

The active toolchain in the pdftract workspace is nightly-x86_64-unknown-linux-gnu, which is required for cargo-fuzz.

3. No error messages about missing fuzz toolchain

✅ PASS - All commands execute successfully with no errors

Additional Verification

• ✅ cargo fuzz --help works correctly, showing all available commands (init, add, build, run, cmin, tmin, coverage, etc.)
• ✅ cargo fuzz list successfully lists 6 existing fuzz targets:
  • cmap_parser
  • content
  • lexer
  • object_parser
  • stream_decoder
  • xref
• ✅ Fuzz directory structure exists with proper layout (fuzz/fuzz_targets/, fuzz/corpus/, fuzz/artifacts/)

Conclusion

The cargo fuzz toolchain is properly installed and fully functional. All acceptance criteria are met.
