-- 错误标注、违规习惯和一次性例外不能直接变为默认记忆。
+- 明确偏好后续可由用户认证确认后立即激活；首个切片只实现隐式候选，不把普通字段编辑冒充明确授权。
+- 隐式出行方式偏好需要同租户、同员工、同场景和同归一化值的 3 个不同 Expense Case 服务端核验纠正，其中至少 2 个出现 `application_approved`，且首尾证据至少跨 7 天；同一 Case、重试、草稿续签只计一票。
+- `accepted`、`client_observed`、`draft_saved` 和单纯 `application_submitted` 只能作为观察信息，不能单独激活；退回、反向纠正、结果 reversed 或制度冲突会抑制现有记忆。
+- Candidate 默认 90 天有效，Active 默认 180 天；状态支持 `candidate / active / suppressed / expired / revoked`。相反值先抑制旧记忆并建立新候选，不原地覆盖；用户“忘记”后立即 revoked，清除可恢复值且不可自动复活。

+- 个人记忆主体优先使用服务端 `employee_id`，缺失时才使用规范化用户名；所有唯一键、读取、证据外键和忘记动作都必须以 `tenant_id` 开头。同邮箱或同员工号在不同租户形成完全独立的记忆。

 - 外部 `/orchestrator/run` 的用户消息、定时任务和系统事件都必须携带有效登录会话，不能由请求体中的 `source` 自行声明可信内部来源；其中 `schedule` / `system_event` 只允许平台管理员触发。服务端使用登录态覆盖用户、租户、角色、管理员、员工、审批人和调度操作人别名，并移除客户端 preview/decision 状态。最近会话查询与删除只使用当前登录用户和租户，查询参数中的 `user_id` 仅保留协议兼容，不参与授权。

 - 反馈投毒：一次点击或违规习惯不能直接成为记忆，需要候选态、最小样本、制度约束和结果权重。
+- 记忆值恢复：现有学习账本只保存 HMAC 指纹，无法恢复具体偏好值；必须由独立记忆表在认证事务中只提取白名单枚举，不能为了复用把自由文本重新塞回账本。
+- 记忆与制度冲突：首个切片的三种交通方式当前均只有估价和舱等规则，没有“禁止某种交通方式”的制度维度；后续一旦增加按职级、路线或金额禁用交通方式的规则，必须先提供服务端允许性判定、抑制原因和回归用例，再允许个人记忆参与预填。
 - 自动化失控：高准确率不代表高风险动作可以无人值守，必须按动作授权并支持 shadow、Canary、抽检和回滚。
 - 虚假节省：风险暴露金额、暂缓付款和工时估算容易被夸大，必须由客户财务确认并执行去重。

+- 2026-07-14（证据信任边界）：记忆证据严格绑定当前 tenant、actor、employee、Case owner 和 Claim owner，并要求 Decision、Feedback、Outcome 指向同一申请、同一 Case 和同一个真实 `application_submitted` 业务事件；事件聚合必须是对应 `expense_claim`。同 Case 重放、invalidated/reversed 事实、最新退回、反向纠正和非白名单纠正不会继续支持 active 记忆。
+- 2026-07-14（应用、抑制与遗忘）：个人记忆只补空白出行方式，任何当前显式值都优先。命中后服务端重新计算交通与总额估算再签发 canonical decision；记忆异常降级为无记忆，不阻塞预览。反向或非白名单纠正抑制 active，用户忘记后状态改为 revoked、清空可恢复值和指纹，旧请求不可复活。
+- 2026-07-14（前端记忆解释）：申请核对表新增独立 `TravelReimbursementMemoryPanel`，展示已应用的常用出行方式、证据数量、学习回执和“忘记此偏好”入口；本地会话快照支持跨刷新恢复，忘记偏好不会篡改当前申请字段。
+- 2026-07-14（个人记忆验证）：容器内个人记忆专项 16 项、记忆/预览决策/迁移/所有权组合回归 56 项通过且 1 项条件跳过、前端申请与记忆组合 83 项通过；一次性 PostgreSQL 迁移循环、Ruff、Vite 生产构建和 `git diff --check` 均通过。当前规则中心尚不存在交通方式禁用维度，制度冲突守卫作为后续规则扩展的前置门禁保留，不以恒真占位判断冒充已实现。
