Benchmark harness (benchmarks/run_benchmarks.py):
- Mount time, readdir, stat latency, file open/read, memory usage
- ENOENT lookup (missing file) benchmark per Oracle review
- Uses synthetic FLAC files from test infrastructure
Results: ALL BENCHMARKS BLOCKED BY BUGS
- Bug #2 (directory tree building) crashes mount with any content
- FSNode.adddir() assumes parent dirs exist, fails with KeyError
- Bug #1 (nested methods) would block FUSE ops even if mount worked
beetfs is non-functional for real-world use until both bugs fixed.
