# ============================================================
# 报告生成 v1（moduleId: domain-reports, 可重生 ✅, 黄金测试 tests/golden/test_m3_knowledge.py）
# plan.md §9.10：M3 落地——排产日报 + 版本对比 + 排产方案报告。
# 生成管线：冻结数据快照 → 结构化章节模板（确定性，数字全部来自快照）
#           → 证据链脚注 → Markdown 导出。
# 硬规则：每个数字可溯源到快照字段；LLM 不参与算数（M3 甚至不参与叙事——纯模板，
#         LLM 润色留到接入密钥后开启，报告可复现性优先）。
