meeting-103 v2.1 clean R2 ✅5/5: PuLID 0.85+Redux 0.5 = pastel 49.99% (전체 best 갱신)

R2 5조합 (5/5 success, retry 2회 포함):
- 2-1: PuLID 0.7 + Redux 0.5 + Stage 3 Refiner (denoise 0.3) → 48.82% (Stage 3 효과 미미)
- 2-2: PuLID 0.7 + Redux 0.7 → 48.93%
- 2-3: PuLID 0.7 + Redux 0.3 → 38.52% (Redux 낮으면 파스텔 감소)
- 2-4: PuLID 0.85 + Redux 0.5 → 49.99% ★ R2 best & 전체 best
- 2-5: 한옥 spring (cherry blossom) → 44.45% / black 4.3%

R1 best (R1-4 48.5%) → R2-4 (49.99%) = +1.5 pp 갱신
R9 legacy (44.5%) → R2-4 (49.99%) = +5.5 pp 누적

학습:
- PuLID weight 0.85 + Redux 0.5 multiply 조합이 0.7/0.5 보다 우월
- Redux 0.3 너무 낮음, 0.7 비슷, 0.85+ 미검증
- Stage 3 Refiner 효과 미미 (48.5% → 48.82%, +0.3pp)

CUDA error 회복:
- 2-3, 2-4, 2-5 첫 시도 CUDA invalid argument
- ComfyUI venv 재시작 후 retry → 3/3 모두 success
- 매 ~5건 후 재시작 패턴 확인됨

자산 라이브러리:
- models-performance: 8 모델 추적
- workflows: winner_auto 4 (R1-4, R2-1, R2-2, R2-4) + partial 5
- prompts/proven: 7 패턴 (R1, R2 합산)

R3 계획:
- 3-1: PuLID 0.7 + Redux 0.85 (push redux 더 강)
- 3-2: PuLID 0.6 + Redux 0.7 (PuLID 약화)
- 3-3: PuLID 0.7 + Redux 0.7 @ 1024x1792 (해상도 증가)
- 3-4: Qwen-Image fp8 + Lightning LoRA 60갑자 (fp8 ~20G 완료, GGUF 회피)
- 3-5: Pony V6 img2img from byeolyi-ref (대안 ID 방법)
