Docs: Phase B completion report
Summary:
- TinyFrontC23Box: Ultra-simple C2/C3 front path implemented
- Performance: +7-15% improvement (128B: 9.55M, 256B: 8.47M ops/s)
- Refill target: refill=64 selected via A/B testing
- 500K stability: Fixed deadlock + node pool exhaustion bugs
- Analysis: User-space optimization reached diminishing returns (99%+ kernel overhead)
- Recommendation: Proceed to Phase 12 (Shared SuperSlab Pool) for step-function improvement
Report includes:
1. Executive summary with key achievements
2. Detailed work breakdown (classify_ptr, TinyFrontC23Box, A/B testing, 500K fix)
3. Performance analysis and why we didn't reach 15-20M target
4. Lessons learned (technical + process)
5. Phase 12 recommendation (mimalloc-style shared SS)
6. Complete performance data appendix
