"""资产负债表取数层重分类引擎（R1~R12，调表不调账） 依据：《CMA 资产负债表重分类规则表 v1》 （`wecom-finance/reports/CMA_资产负债表重分类规则表_v1.md`，任总 2026-09-16 批准落地） 本模块只作用于**报表取数层**：`voucher_details` 只读，**不生成记账凭证、不改账簿** （调表不调账；账实不符走差错更正，见规则表 §四）。 口径要点 -------- 1. **余额方向**：资产类 NSB = Σ(借−贷)；负债/权益类 NSB = Σ(贷−借)。NSB = normal-side balance。 2. **触发**：NSB < 0（明细科目反方向余额，如预收账款出现借方余额）→ 转正额 = |NSB|， 移入目标报表项目（准则 30 号「不得抵销」）。 3. **全部触发判定基于原始余额**（单遍、顺序无关、可重复执行/幂等）——避免 R3/R4 这类互为镜像 的规则互相影响（如 2202 应收账款 ↔ 1123 预付账款 双向都有反向余额时）。 4. **科目取数一律前缀匹配**（`subject_code LIKE '1122%'`，与规则表 §二 公式一致）：CMA 科目为多级 （100101 / 22210101 / 310415），精确匹配会漏掉全部明细行。 5. **basis**：`end` = 期末余额（累计至 period，含期初/结转，资产负债表口径，默认）； `period` = 本期发生额（兼容旧报表口径）。 6. **不变量**：跨方向重分类（资产↔负债）使资产合计与负债合计**同额增加**， 故「总资产不变」只在同侧列报下成立；真正恒定的不变量是 `Δ资产合计 = Δ负债合计` 且 `资产合计 − 负债合计 − 所有者权益合计` 前后不变。 本模块把这两条都算出来（`invariants`），不隐藏 `total_assets_unchanged=False` 这一事实。 """ from __future__ import annotations from dataclasses import dataclass, field from decimal import Decimal from typing import Dict, List, Optional, Sequence, Tuple from sqlalchemy import func from app.utils.voucher_guard import apply_voucher_guard RULE_VERSION = "reclass-v1.0-20260916" DEFAULT_TOL = 0.01 #
