 - 复查中核过、确认不是问题的两点：其一，网关放宽的作用域正确——`/api/*` 走 `is_generic_api_proxy_path`，读超时默认 `3600` 秒，远高于服务端 90 秒预算与客户端 120 秒，次序是 `90 < 120 < 3600`，网关不会在服务端合法工作期间截断，它合成 502/504 只可能是连接失败或进程不可用，确属未知结果；唯一变数是有人把 `GENARRATIVE_PINGORA_GATEWAY_UPSTREAM_API_READ_TIMEOUT_SECONDS` 调到 90 秒以下。其二，`projectHasUnresolvedGenerationDialog` 由 `some(...)` 改为「取首个匹配再判」存在极低风险的语义收窄，同 id 多 dialog 时行为不同，但 id 唯一，实际不可达。

+## 2026-08-03 inline 占位补到期清理，收掉存活窗口引入的回归
+
+- 缺陷：存活窗口把「立即刷新也能清掉孤儿占位」这条旧行为换掉了。剥离只在项目首次加载执行一次，窗口内被保留的占位再没有任何东西会重新判定——页面保持打开就一直转，必须等到用户下一次加载且距创建已满窗口才收口。这是引入 TTL 时的已知取舍，本次补上。
+- 复查中发现的关键事实：**手动收口入口本来就存在**——`requestRemoveCanvasGenerationDialog` 已接入键盘快捷键，对 `generating` 占位会先弹确认再删。所以缺的从来不是删除手段，而是「它已经死了」这个信号；占位看起来和正在干活一模一样。
+- 决策：加一次性到期定时器，到点走与加载期**完全一致**的处置——移除 + 同一条文案（抽成 `DEAD_INLINE_PLACEHOLDER_NOTICE` 共用）。未采纳「标记 failed 而不移除」：`failed` 会被自动保存持久化，而剥离只处理 `generating`，那张卡片会跨刷新长期存在，与当初选「刷新后占位消失」的用意相反，把一次性噪音变成永久残留。
+- 三条必须守住的实现约束，都写进了 hook 的文档注释：其一，到期回调只推进 tick 让 effect 重跑，判定始终在 effect 体里用当前 dialogs 和当前时间做——挂上定时器之后占位可能已被拥有者会话正常收口，按闭包旧值行动会清掉一个已完成的占位；其二，清理用底层 `removeCanvasGenerationDialogById` 而不是 View 的 `removeCanvasGenerationDialog`，后者是用户主动删除的语义（写 `delete-generation-result` 历史、清空选中、切回选择工具），自动清理记用户没做过的历史、抢走当前选中态都是错的，加载期剥离同样不做这些；其三，本会话自己在途的占位不会被误清（客户端 120 秒就 abort，catch 会把它推离 `generating`），但不依赖该推理，靠第一条的重新判定兜住。
+- 作用面划分：`dropDeadInlineGenerationPlaceholders` 跑在**快照**上、只在加载时执行；`collectExpiredInlineGenerationDialogIds` / `resolveNextInlineGenerationDialogExpiryAt` 跑在**内存 dialog** 上、供页面打开期间使用。同一条规则、两种数据形状，边界（到期时刻含等号不算过期）与缺时间戳的兜底方向都保持一致。
+- 到期时刻可精确计算，所以挂一次性定时器而不是轮询；多给 50ms 余量，避免贴着到期时刻醒来判定为未到期、白白多挂一轮。
+- 验证：纯函数四条用例覆盖边界、队列型与已终态不到期、缺时间戳立即到期、最早到期时刻；hook 四条覆盖到期清理、醒来重新判定（占位期间被收口则不清）、队列型永不挂定时器、已超窗立即清理。去掉定时器重挂逻辑后第一条变红。`vitest src/components/image-editor` 916 通过 / 73 文件，typecheck、eslint、check:encoding 通过。
