+## Runtime pending 恢复不能让大型 async frame 共用默认 worker 栈（2026-08-03）
+
+- 现象：Supervisor collaboration durable isolated spawn 恢复测试在默认 Tokio worker 栈下稳定 `stack overflow`；单独运行同样失败，提高 `RUST_MIN_STACK` 后通过。
+- 原因：不是业务递归。debug 构建中 pending action continuation、后台 task queue 和 Agent 主循环各自形成大型 async poll frame；恢复路径在同一次 poll 调用链直接进入下一层状态机，累计超过 worker 默认栈。
+- 处理：整个 pending continuation、它进入的后台主循环，以及完成、取消或失败后 drain 同 Agent 后续队列时，都必须跨越独立 Tokio task 轮询边界，使上层 poll 先退栈后再轮询下一层状态机。传入边界的 future 必须先装箱；若泛型 helper 直接持有大型 future，即使随后 `spawn`，调用方 async frame 仍会把它保留在默认 worker 栈上。边界必须保留结构化取消语义；当前使用 boxed future 与 `JoinSet`，父 continuation 被丢弃时同步 abort 子任务。不得只增大 CI 的 `RUST_MIN_STACK`，否则生产默认栈仍可能崩溃。
+- 验证：失败用例必须在未设置 `RUST_MIN_STACK` 时通过；同时覆盖 policy batch 全组、拒绝 pending 后重规划并 drain 下一任务，以及 pending/cancellation 回归，证明恢复不重复生成 isolated spawn、队列继续推进且父任务取消不遗留后台子任务。
+- 关联：`apps/ai-game-creator-shell/src-tauri/src/agent/runtime_driver/pending_execution.rs`。

 ## Provider 可扩展不能用一个全局 protocol 枚举代替实例隔离
 
 - 现象：把 `openai_chat / openai_responses / anthropic` 直接当 Provider 身份，注册第二个同协议 endpoint 时发生 ID 冲突；或为方便调用把 API Key、base URL、raw-log 目录放进全局状态，并行请求后日志串目录。
