 `bumpTokenVersionTx`(或 `RevokeSessions`)使旧 JWT 失效，并按第 6 节携带
 `TokenProof`、接续操作者会话。因子写入与版本递增不得拆成两个独立提交。

-## 4. 「至少一种登录方式」不变量
+滑动续期(`MaybeRenew`)是唯一的非敏感换发:剩余有效期 < `renewThreshold`
+且请求方法为 GET/HEAD 时,经 `X-Renewed-Token` / `X-Renewed-Expires-At`
+响应头换发**同 jti、同版本**新令牌并延长会话行。写请求不得预生成续期头:
+handler 可能撤销会话或递增版本,导致响应到达时头中令牌已经失效。续期不 bump
+版本、不新建会话行;新增登录方式不得绕过此约定自行签发长时令牌。
+
+## 4. 场景：滑动续期响应头
+
+### 1. Scope / Trigger
+
+已鉴权 GET/HEAD 请求携带的 JWT 剩余有效期低于 `renewThreshold` 时触发。
+
+### 2. Signatures
+
+```go
+func (s *AuthService) MaybeRenew(
+    ctx context.Context, token string,
+) (renewed string, expires time.Time, ok bool)
+```
+
+成功时响应携带 `X-Renewed-Token` 与 RFC3339 格式的
+`X-Renewed-Expires-At`;客户端只在 HTTP 2xx 时应用。
+
+### 3. Contracts
+
+- 新 JWT 沿用原 `jti + Ver`,基础 TTL 仍为 24h。
+- 写响应不携带滑动续期头;敏感写接口以响应体中的新会话为准。
+- `user_sessions.expires_at` 更新成功后才能返回 `ok=true`;数据库失败不得发头。
+- 无会话行的兼容期旧 JWT 可续期,但不得新建会话行。
+
+### 4. Validation & Error Matrix
+
+| 条件 | 结果 |
+| --- | --- |
+| GET/HEAD 且剩余 <12h、持久化成功 | 返回双响应头 |
+| GET/HEAD 且剩余 ≥12h | 无续期头 |
+| POST/PUT/PATCH/DELETE | 无续期头 |
+| JWT 解析或会话延期失败 | `ok=false`,无续期头 |
+| 非 2xx 响应意外携带续期头 | 客户端忽略,不写 Store |
+
+### 5. Good/Base/Bad Cases
+
+- Good：列表 GET 续期后,会话行过期时间与新 JWT 对齐。
+- Base：普通写请求由原 JWT 完成,不做滑动续期。
+- Bad：在 `c.Next()` 前为写请求签头,handler 随后 bump 版本或 Logout。
+
+### 6. Tests Required
+
+- 路由测试断言临期 GET 返回头、临期敏感 POST 不返回头。
+- 服务测试先把会话行缩短,再断言续期确实延长该行。
+- 注入数据库更新失败,断言 Token/expiry 为空且 `ok=false`。
+
+### 7. Wrong vs Correct
+
+```go
+// Wrong：所有鉴权请求都预生成续期头
+maybeRenewToken(c, auth, token)
+
+// Correct：只读请求才允许滑动续期
+if allowsSessionRenewal(c.Request.Method) {
+    maybeRenewToken(c, auth, token)
+}
+```
+
+## 5. 「至少一种登录方式」不变量
