"""tests/docgen/test_intent_cases.py —— DC-INTENT-CASES-01~30（后端 pytest）。

唯一事实源：docs/team/cases_intent.md（30 条表，测试用副本 tests/docgen/cases_intent.md）。
数据文件：tests/docgen/data/intent_cases.json（由本文件从冻结表转写，转写后与 cases_intent.md 核对）。
执行：bash tests/docgen/run_all.sh intent（后端）；前端同表双跑见 test_intent_frontend.mjs。
