# bf-1jx4r: Verify build artifacts and output

## Task
Verify that the cargo fuzz build produced the expected binary artifacts for the `profile_yaml` fuzz target.

## Verification Results

### Acceptance Criteria Status

✅ **PASS** - profile_yaml binary exists in the fuzz build output directory
- Location: `/home/coding/pdftract/fuzz/target/x86_64-unknown-linux-gnu/release/profile_yaml`

✅ **PASS** - File has non-zero size
- Size: 58M (58,541,912 bytes)
- Comparable to other fuzz targets (57-58M range)

✅ **PASS** - Binary is executable
- Permissions: `-rwxr-xr-x` (owner: read/write/execute, group/other: read/execute)

✅ **PASS** - Build artifacts match expected structure
- All fuzz targets follow same pattern:
  - `content`: 57M
  - `cmap_parser`: 57M
  - `lexer`: 57M
  - `profile_yaml`: 58M
  - `stream_decoder`: present
  - `xref`: present
  - `object_parser`: present

### Functional Test

Tested the binary with correct library path (NixOS requires explicit LD_LIBRARY_PATH):
```bash
LD_LIBRARY_PATH=/nix/store/chqq8mpmpyfi9kgsngya71akv5xicn03-gcc-15.2.0-lib/lib \
  /home/coding/pdftract/fuzz/target/x86_64-unknown-linux-gnu/release/profile_yaml
```

Result: ✅ libFuzzer initializes successfully, shows expected startup messages:
- Seed value assigned
- 1 module loaded with 13,269 inline 8-bit counters
- 1 PC table loaded with 13,269 PCs
- Max input length: 4096 bytes (default)
- Corpus discovery begins

## Summary

The cargo fuzz build for `profile_yaml` completed successfully and produced a fully functional fuzzing binary. The artifact matches the expected structure and size of other fuzz targets in the project.

## Build Context
