# Bead bf-5kd: Sanitization Benchmark Scaffold

## Status: Already Implemented

All deliverables and acceptance criteria were already in place:

### Deliverables Status
- ✅ **benches/ directory structure**: Already exists
- ✅ **Criterion dependency**: Already configured in Cargo.toml (v0.5)
- ✅ **benches/sanitize.rs**: Already exists with comprehensive benchmark suite
- ✅ **Smaller sample sizes**: Already configured (sample_size(10) in all benchmark groups)

### Acceptance Criteria Verification
1. ✅ `benches/sanitize.rs` exists and compiles
2. ✅ `cargo bench --bench sanitize` runs successfully
3. ✅ Criterion dependency properly configured

### Current Implementation
The benchmark suite is production-ready with:
- Three trace size benchmarks (10KB, 100KB, 1MB)
- Median latency measurement
- Skip rate statistics reporting
- Assertion-style performance test (configurable threshold)
- Configurable sample counts and thresholds via environment variables
- Throughput measurements in MiB/s

### Benchmark Results (Sample Run)
```
sanitize_10kb/throughput:  1.32 ms (7.38 MiB/s)
sanitize_100kb/throughput: 11.37 ms (8.59 MiB/s)
sanitize_1mb/throughput:   125.37 ms (7.98 MiB/s)
median_latency/100kb:      9.66 ms
```

No changes were required - the scaffold was already fully implemented.
