Content-Transfer-Encoding: 8bit - 新增 test_viral_video_wiring.py：9 个集成测试覆盖四步接线全流程 - image_analysis / intent_parsing 走 loader + XML 解析 - storyboard 三档 fusion_level 注入 system_prompt - review 走 Reviewer 且 pass/rewrite 两条路径正确 - 端到端验证每步都调用 prompt_loader - 修复 test_script_generation_returns_copy_result：mock 改为返回 XML 字符串 - 修复 test_review_pass_v16：mock Reviewer.review 返回真实 ReviewResult - viral_video.py 增加 import re，_xml_to_product 的 text_on_package 同时从子标签读取（兜底） - prompts.py _STORYBOARD_SYSTEM 改为普通字符串 + {fusion_instruction}/{global_constraints}/{negative_rules} 占位符，支持运行时注入 全量 viral_video 单测 150/150 通过，无回归。 Closes #2040 --- apps/worker/worker_app/tasks/viral_video.py | 4 + packages/application/viral_video/prompts.py | 8 +- tests/unit/test_viral_video.py | 58 ++--
