+/**
+ * 契约级单测：能力键 {@code family.familyMembers.removeMember}（移除/退出家庭成员后的会员身份重算）。
+ *
+ * <p><b>溯源·需求</b>：{@code tests/user-scenarios/应用场景总览.md} SC-P-06（移除/删除成员，业务域 A 家庭与成员管理）。
+ * <p><b>溯源·设计</b>：{@code docs/superpowers/api/API_REFERENCE.md} §4.2
+ * {@code POST /api/family/member/kick}（移除成员）/ {@code POST /api/family/member/leave}（主动退出家庭），
+ * 均已合入 origin/cfclub。</p>
+ *
+ * <p><b>用户实测缺陷</b>：用户被从家庭会员家庭移除后未恢复免费身份——
+ * {@code users.member_level / member_expire_time} 缓存残留（仍在 FAMILY），
+ * {@code MembershipService.getMemberLevel} 取 personal 与 family 高者仍返回 FAMILY。
+ * <b>期望</b>：kick/leave 后被踢用户如无个人独立更高等级会员则恢复 FREE。</p>
+ *
+ * <p><b>实现链现状（缺陷定位）</b>：
+ * <blockquote>
+ *   {@code FamilyMemberService.kickMember()} 仅调用 {@code membershipService.reconcileFamilyMembership(oldFamilyId)}
+ *   （会先迁移被踢用户 familyId → 初始家庭，再对原家庭查全部成员）——被踢用户已迁出，不在
+ *   {@code downgradeFamilyMembers} / {@code syncMembershipToFamilyMembers}（只升不降）的查询范围，
+ *   其 {@code users.member_level} 缓存原样残留；{@code leaveFamily()} 同样只核原家庭。
+ *   {@code MembershipService.getMemberLevel(userId)} 把缓存值当「个人维度」参与取高，
+ *   新家庭无有效会员（family=FREE）时仍返回缓存的 FAMILY。
+ * </blockquote></p>
+ *
+ * <p><b>修复方向（GREEN 升级指引）</b>：kick/leave 对被踢用户按「个人维度」重算会员缓存——
+ * 仅清除源自家庭会员的缓存（等级 + 到期时间），保留更高等级独立个人会员；若无独立更高等级则恢复 FREE。
+ * 本测试以「结果契约」断言（被踢用户落库的 member_level / getMemberLevel 返回值），不预设具体方法名，
+ * 实现即可自主选择改造路径（新方法或对新家庭维度的重核），只要结果符合契约即转绿。</p>
+ *
+ * <p><b>RED 预期</b>：本分支 src/main 未落地该重算逻辑——「恢复 FREE」「getMemberLevel 重归 FREE」
+ * 类用例应失败（红，4 例）；「保留更高个人会员」「权限守卫」类用例当前已具备应为绿（用于锁定
+ * GREEN 不得误清个人高等级会员、不得放开权限规则）。纯 Mockito / 反射，无 Spring / 无 DB / 无外部服务。</p>
