bf-4zhtc: Validate profile_yaml fuzz harness source code

Date: 2026-07-06 Status: PASS

Acceptance Criteria Validation

✓ fuzz/fuzz_targets/profile_yaml.rs exists and is readable

  • File exists at /home/coding/pdftract/fuzz/fuzz_targets/profile_yaml.rs
  • File size: 766 bytes
  • Readable and properly formatted

✓ File contains valid Rust code structure

  • Correct #![no_main] attribute for fuzz targets
  • Proper use libfuzzer_sys::fuzz_target; import
  • Valid fuzz_target!(|data: &[u8]| { ... }); macro usage
  • Expected rustc error about libfuzzer_sys is normal for fuzz-only dependencies

✓ No obvious syntax errors when viewing the file

  • Proper UTF-8 handling with early return on invalid UTF-8
  • Clean closure structure
  • Well-documented with INV-8 (no panic at public boundary) reference

✓ Imports match patterns used in other working fuzz targets

  • Pattern matches other targets (content.rs, cmap_parser.rs, stream_decoder.rs)
  • Uses same libfuzzer_sys::fuzz_target pattern
  • Follows same documentation style with INV-8 reference

✓ Target function exists

  • Verified pdftract_core::profiles::load_profile_yaml exists in crates/pdftract-core/src/profiles/loader.rs
  • Function signature: pub fn load_profile_yaml(content: &str) -> Result<Value, ProfileLoadError>

✓ Cargo.toml configuration

  • libfuzzer-sys = { version = "0.4", features = ["arbitrary-derive"] } properly configured
  • pdftract-core = { path = "../crates/pdftract-core", features = ["profiles"] } includes profiles feature
  • [[bin]] target for profile_yaml properly registered (lines 43-45)

Conclusion

The profile_yaml fuzz harness source code is valid and properly configured. No issues found. Ready for build testing.
