 - 本轮修正后，`src/codex/accounts/service/refresh.rs` 提供 `probe_account_refresh()`，用于执行 OAuth refresh 探测但失败不直接落库状态；admin/manual refresh 仍通过 `refresh_account()` 应用结果。
 - 本轮修正后，`src/codex/tasks/token_refresh.rs` 后台调度器调用 `probe_account_refresh()`，只有 `AccountProbeOutcome::Alive` 视为成功，`Dead` 会进入重试与 permanent threshold 判断；第二次 permanent failure 后才写入 expired/banned。
 - `src/codex/tasks/token_refresh.rs` 单元测试 `do_refresh_inner_should_mark_expired_only_after_second_permanent_failure` 覆盖连续两次 `InvalidGrant` 前数据库状态仍为 `active`，第二次失败后才写入 `expired`。

 - `src/codex/gateway/oauth/client.rs:402-423` 把 `quota`、`banned`、`token_revoked` 等映射为结构化 `RefreshFailure`。
 - 本轮修正后，`src/codex/accounts/service/health.rs` 健康检查通过 `refresh_account()` 调用 OAuth refresh token 链路，不再访问 Codex usage endpoint；`tests/admin/accounts/cookies_quota.rs` 断言 `/api/codex/usage` 调用次数为 0。

 - 每账号 refresh 防重已经存在，Rust 用 SQLite lease 替代文件锁，语义上更适合当前数据库架构。

 - 后台 refresh 调度器已不再把 `Dead` probe 误判为成功；scheduler 路径 permanent failure 的状态写入已延后到连续两次失败。
+- 后台 refresh 调度器的临时错误耗尽语义已与原版一致：不把账号标为 expired，恢复为 active，并安排 10 分钟 recovery。

 - 原版 refresh 对一次性 RT 的网络错误非常谨慎，只有请求确认未到服务器时才 fallback/retry；Rust 当前 `reqwest` refresh client 不能区分 pre-flight 与 mid-flight 失败，且 runtime 调度器错误处理路径与原版不等价。
 
 缺口/后续动作：
-- 增加 transport error 的后台恢复调度测试，覆盖非 permanent 错误耗尽重试后进入 10 分钟恢复调度。
+- 若要继续把 refresh client 做到原版级细粒度，需要区分 refresh token 请求的 pre-flight 网络失败与 mid-flight 失败，避免一次性 RT 被服务器接收后仍重试。
