铁律合规: - P0: 移除三处硬编码API密钥 → lib/secrets.py 三层查找 - P0: 统一LIB/engines调用关系(tts复用音色表,composer桥接editor) - P0: batch支持参数+batch-resume断点续传 - P0: Seed一致性(seed_value/lock_seed字段+gen --lock-seed) - P0: 跨集资产继承(inherit命令)+A/B对比(compare命令) - P1: concat逻辑修复/滤镜崩溃修复/FFmpeg路径统一/成本追踪 - P2: 状态判断修复/CLI --help+--version+模糊匹配 - 新增: 65条命令(原17条)覆盖全链路 - 新增: deps/info/note/history/report/flow/director等 - 语法OK 零重复函数 零密钥泄露
