ci/woodpecker/push/main Pipeline was successful
ASK-20261014-04（任总 2026-10-14 11:20「放行4」）批后口径： - §4-1 博海固定成本弃净额：6601/6602/6603 仅借方（133.98 万，2026-01..09）；2026-03 单月由 -9.02 万转正； 6603 贷方（现金折扣收益 64.40 万）改 finance_income_terms 单列备查，不进固定成本/末行/勾稽。 - §4-2 博海变动成本追加 6403 营业税金及附加（530.17 万）。 - §4-3/§4-4 维持现行（酣客收入/边际贡献基数不动）。 - §4-5 管理利润表页加「数据批次/导入时刻」纯展示备注（import_logs）。 - 口径唯一源仍为 bep_caliber.ENTITY_CALIBERS；报表/卡面/派生器一律经 fixed_cost_spec() 解析（读口写口一致）。

"""管理利润表「真实科目取数」重建单测 — project-20261014-cma-profit-summary-real-data-rebuild（2026-10-14）
|
||
|
||
背景（代码级审核实锤的 3 处硬伤，本文件逐条设负对照）：
|
||
① 原 `reports.py` L74 `contribution_margin = gross_profit`（边际贡献=毛利）；
|
||
② 原 L76 变动成本 = 营收 × 硬编码比例（五成）；
|
||
③ 原末行标签「＝ 息税前利润」却装净利率算出的 net_profit；且纵向勾稽对不上。
|
||
|
||
断言分组：
|
||
L1 逐行可对到真实科目 —— 每行 = 该 entity 口径下真实科目发生额（`rows.parts.by_subject` 留痕）
|
||
L2 无硬编码比例 / 无 KPI 比率倒推（AST+源码级负对照）、标签与算法一致、勾稽自检生效（含不平负对照）
|
||
L3 按 entity 隔离 —— e1（酣客）/e2（博海）各读自己的科目集；口径改动只改 ENTITY_CALIBERS 即自动跟随
