…#10) Three small surgical fixes backed by 5-case offline evidence (10 images): A. removeBackground: COMPAT_API_URL -> DASHSCOPE_SUBMIT_URL (native endpoint) wan2.7-image-pro image-edit ability is NOT exposed via OpenAI compat layer. Prod silently swallowed errors and returned the original white-bg image. Offline: compat-mode 0/6, native 8/10. Real root cause for the 'all-white' user complaints. B. PROMPT_MODEL: qwen3.6-plus -> qwen3.6-max-preview enable_thinking already on. One-line change. C. critique pass: second LLM call detects 4 drift classes (D1 subject_replacement / D2 keyword_omission / D3 style_inversion / D4 topic_drift) and emits a fixed pair when verdict=fix. Adds the counterexample reasoning only; SYSTEM_PROMPT positive examples untouched. Offline hit rate: 2/5 (40%). Best-effort: any failure falls back silently to the original variants. Out of scope (deliberately not done): - vl-plus visual verification (latency vs. marginal gain) - retry on failed cut (one-shot, fall back to original) - alternative cut backends (birefnet etc.) Closes #10 Refs T-121

synthesizePrompts解析校验完后追加第二次 LLM 调用SYSTEM_PROMPT_CRITIQUE：仅检测 4 类 drift（D1 subject_replacement / D2 keyword_omission / D3 style_inversion / D4 topic_drift）不做
