meeting-103 v2.1 clean R3+R4 ✅: PuLID 0.7+Redux 1.0 = pastel 56.41% (전체 best 갱신)

R3 (4/5 success):
- 3-1: PuLID 0.7 + Redux 0.85 → 50.47% (R2 best 49.99% 갱신)
- 3-2: PuLID 0.6 + Redux 0.7 → 49.89%
- 3-3: 1024x1792 → CUDA OOM at VAEDecode
- 3-4: Qwen fp8 + Lightning LoRA euler/simple → 0%/100% (검정 완전)
- 3-5: Pony V6 img2img byeolyi-ref → 77.3% (img2img 0.65 denoise, 원본 색 보존)

R4 (3/5 success, 별이 새 best):
- 4-1: PuLID 0.7 + Redux 1.0 (max) → 56.41% ★ 전체 best
- 4-2: PuLID 0.85 + Redux 0.7 → 50.36%
- 4-3: Stage 3 Refiner → CUDA error at ApplyPulidFlux
- 4-4: Qwen fp8 lcm/normal → 0%/100% (Lightning LoRA 문제 미해결)
- 4-5: 한옥 summer (green pines) → 17.7%/3.97%

학습:
- Redux strength 0.5 → 0.7 → 0.85 → 1.0 단조 증가 (56.41% sweet spot)
- PuLID 0.7 fixed, Redux 1.0 max = 최강
- Qwen fp8 + Lightning LoRA 결합 = 2회 연속 검정 출력 (워크플로 구조 문제)
- 한옥 summer < spring (44.45%) — 색감 자체가 차분

진행: R9 legacy 44.5% → R1 48.5% → R2 49.99% → R3 50.47% → R4 56.41% (+11.91pp)

자산 라이브러리:
- workflows: winner_auto 7 + partial 7
- prompts/failed: 9 패턴 (Qwen 계열 2건 추가)
