"""check_ids_new.py — 编号门禁·新增行（**已退役 2026-10-29，用户裁定**；本脚本降为手工报告工具）

退役口径：钩子已从 .pre-commit-config.yaml 摘除（YAML 解析条目 52 → 51），编号形态此后
**没有机器面**——靠 docs/编号规范.md §1 的默认答案（一律停发）+ 评审。留档说明 → docs/门禁说明/id-check-new.md。
本脚本与 check_ids.py（2026-10-28 退役的全库八项校验）同处一档：手工复查「这批改动 / 这段历史
里有没有野生编号」时才跑，跑不跑都不影响提交。

判据（三条，都不依赖任何族清单 / 游标 / 属主登记处）：
  1. 破折形态（形如 前缀-数字，或 前缀-段-数字）：首段不在 KNOWN_DASH → FAIL；
     在 RETIRED_DASH（已停发族）→ 只 WARN（不拦，提示改语义短语）。
  2. 裸形态（大写字母紧跟数字，如 TIM3 / YX15 / TPAFE5160）：前缀不在 KNOWN_BARE → FAIL。
  3. 单字母+数字（C12 / U15 / L3 / R3）→ **放行**：元件位号与层次号同形，这是本脚本的已知盲区
     （与旧门禁的"裸形盲区"同源，见 docs/门禁说明/id-check-new.md §5）。

用法（仓库根；钩子摘除后没有自动调用者，四条都是手工）：
  python scripts/archive/id_gate/check_ids_new.py                # 查暂存区
  python scripts/archive/id_gate/check_ids_new.py --worktree     # 查工作区未暂存的改动
  python scripts/archive/id_gate/check_ids_new.py --range A..B   # 查一段提交的新增行
  python scripts/archive/id_gate/check_ids_new.py --self-test    # 内建正反例自检（改脚本后必跑）
退出码：0 = 通过 / 仅告警；1 = 新增了未知编号；2 = 环境错误。
豁免：行内含 [示例] / [计划] 的行按冻结口径跳过；确需保留的写法在同一行写 [编号豁免]。
