# ---- INV-013: Matchmaker不能读取Counseling正文 ----
# Phase 23 KEEP-VERIFY（2026-09-18）：原 test_matchmaker_cannot_read_counseling_body
# 的函数体为 `pass` 空壳（注释自述「在当前测试框架下简化验证」），从未真实断言过任何权限，
# 却在 docs/STATUS.md 中被计为 P23-T06「咨询 E2E ✅」的一部分。
# 计划 Phase 23 Gate「不允许 skip/pass 空壳」→ 已移除该空壳。
#
# INV-013 现由后端真实行为用例覆盖：
#   backend/.../invariants/V11InvariantsTest#inv013MatchmakerCannotReadCounselingBody
#   走真实 CounselingService.getDetail：断言 Matchmaker 读到的 user_request_summary 为 null，
#   并以「assigned Counselor 能读到正文」作反证，避免全局脱敏造成的假阳性；
#   已通过负向注入验证（把 isMatchmaker 分支改为返回全文 → 该用例精准变红）。
#
# E2E 层待补场景：用真实红娘 token 调用咨询详情接口并断言被拒。
