- unified_render_service filter_complex Step1 trim 时长改为 effective-freeze（与直通路径同口径，tpad 补冻结） - test_duration_compensation / render_audio_utils / render_audio_pure / 两处 render_layer_utils：min(duration,actual) 断言改为目标段长为准 - estimate_total_duration 测试：cut 零重叠、非 cut 逐处扣转场（FakeClip 加 transition_effect/duration） - test_generation_tasks/preview：voice_ids kwarg/字段移除，配音改 voice_library_id
