Moe Charm (CI)	94e7d54a17	Tiny P0/FC tuning: per-class FastCache caps honored; defaults C5=96, C7=48. Raise direct-FC drain threshold default to 64. Default class7 direct-FC OFF for stability. 256B fixed-size shows branch-miss drop (~11%→~8.9%) and ~4.5M ops/s on Ryzen 7 5825U. Note: 1KB fixed-size currently SEGVs even with direct-FC OFF, pointing to non-direct P0 path; propose gating P0 for C7 and triage next (adopt-before-map recheck, bounds asserts). Update CURRENT_TASK.md with changes and results path.	2025-11-10 00:25:02 +09:00

Tiny: enable class7 (1024B) fast_cap by default (64); add 1T A/B switch for Remote Side (HAKMEM_TINY_ASSUME_1T)

Changes
- core/hakmem_tiny_config.c: set g_fast_cap_defaults[7]=64 (was 0) to reduce SuperSlab path frequency for 1024B.
- core/tiny_remote.c: add env HAKMEM_TINY_ASSUME_1T=1 to disable Remote Side table in single‑thread runs (A/B friendly).

A/B (1T, cpu2 pinned, 500k iters)
- 256B: cycles ↓ ~119.7M → ~60.0M, time 95.4ms → 83.2ms (~12% faster), IPC ~0.92→0.88, branch‑miss ~11%.
- 1024B: cycles ↓ ~74.4M → ~27.3M, time 83.3ms → 73.5ms (~12% faster), IPC ~0.82→0.75, branch‑miss ~11%.

Notes
- Branch‑miss率は依然高め。今後: adopt境界の分岐整理、超シンプルrefill（class7特例）/fast path優先度の再調整で詰める。
- A/B: export HAKMEM_TINY_ASSUME_1T=1 で1T時にRemote SideをOFF。HAKMEM_TINY_REMOTE_SIDEで明示的制御も可。

Debug Counters Implementation - Clean History

Major Features:
- Debug counter infrastructure for Refill Stage tracking
- Free Pipeline counters (ss_local, ss_remote, tls_sll)
- Diagnostic counters for early return analysis
- Unified larson.sh benchmark runner with profiles
- Phase 6-3 regression analysis documentation

Bug Fixes:
- Fix SuperSlab disabled by default (HAKMEM_TINY_USE_SUPERSLAB)
- Fix profile variable naming consistency
- Add .gitignore patterns for large files

Performance:
- Phase 6-3: 4.79 M ops/s (has OOM risk)
- With SuperSlab: 3.13 M ops/s (+19% improvement)

This is a clean repository without large log files.
