jedarden 6c9db2da89 test(bf-1jx4r): verify profile_yaml fuzz build artifacts 
Verification summary:
- profile_yaml binary exists at fuzz/target/x86_64-unknown-linux-gnu/release/profile_yaml
- File size: 58M (non-zero, reasonable)
- Execute permissions: -rwxr-xr-x
- Structure matches other fuzz targets (57-58M range)
- Functional test: libFuzzer initializes successfully

Closes bf-1jx4r.

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):

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.
