# R3-SHORTAGE regression script — S8-REGRESSION-FIXTURE-1 重构版（dev/test only, aidopdev）。
#
# 演变史：
#   - 旧版基于 G01_TEST_SHORTAGE 旧 fixture（id=53）。当前 dev 已无 SHORTAGE demo 规则。
#   - 重构后：找不到 SHORTAGE demo fixture → record_skip + exit 0。
#   - 任务 CTO 约束 六.F：不得 FAIL；不得自动创建 SHORTAGE TEMP fixture（除非有稳定方案）。
#
# 为日后 SHORTAGE 演示规则上线时启用，环境变量 RULE_CODE 可指定其他 SHORTAGE rule_code。
