Moe Charm (CI) 5c9b09148b Phase 69-0: Refill tuning design memo (parameter sweep plan)
Changes:
- docs/analysis/PHASE69_REFILL_TUNING_0_DESIGN.md: New design document
  * Identified 3 tunable parameters: refill batch size, unified cache C5-C7 capacity, warm pool size
  * Sweep plan: single-parameter isolation → combined optimization
  * Expected gain: +3-6% (shortest path to M2: 55% target)
  * Risk assessment and decision criteria (GO/Strong GO/NO-GO thresholds)

- CURRENT_TASK.md: Phase 69-0 marked complete, Phase 69-1 (sweep execution) set Active

Key Parameters Identified:
1. TINY_REFILL_BATCH_SIZE: 16 → 32/64 (expected +1-3%)
2. Unified Cache C5-C7: 128 → 256/512 slots (expected +1-2%)
3. Warm Pool: 12 → 16/24 SuperSlabs (expected +0.5-1%)

Strategy:
- ENV-only sweeps first (warm pool, cache capacity) - no recompile
- Batch size sweep requires PGO rebuild - highest expected gain
- Combined optimization targets +3-6% additive gain
