-## Cost Optimization / 成本优化
-
-### Current Usage / 当前使用
-- ✅ Path filters to skip unnecessary runs
-- ✅ Caching for dependencies
-- ✅ Parallel job execution
-- ✅ Conditional execution
-
-### Additional Optimizations / 额外优化
-1. Use `concurrency` to cancel outdated runs
-2. Implement smart caching for build artifacts
-3. Use `actions/upload-artifact` for sharing between jobs
-4. Consider using ARM runners for cost savings (10x cheaper)
-5. Implement workflow-level caching strategies
-
----
-
-## Security Best Practices / 安全最佳实践
+## Cost & Security Best Practices / 成本与安全最佳实践
 
 ### Current / 当前
-- ✅ Minimal permissions (`contents: read` mostly)
-- ✅ `pull_request_target` for untrusted code
-- ✅ Third-party action pinning
-- ✅ Secret scanning enabled
-
-### Recommended / 推荐
-1. Use GitHub Environments for deployment protection
-2. Implement branch protection rules
-3. Require status checks for merge
-4. Use Dependabot for automated updates
-5. Regular security audits of workflows
-6. Implement CODEOWNERS file
-7. Use signed commits for releases
-
----
-
-## Monitoring / 监控
-
-### Metrics to Track / 要跟踪的指标
-
-| Metric | Tool | Purpose |
-|--------|------|---------|
-| Workflow success rate | GitHub Actions | CI reliability |
-| Average runtime | GitHub Actions | Performance |
-| Code coverage | Codecov | Test quality |
-| Vulnerabilities | cargo-audit/deny | Security |
-| Dependency freshness | Dependabot | Maintenance |
-| Benchmark results | Criterion | Performance |
-| Flaky tests | pytest-flaky | Stability |
-
----
-
-## Maintenance / 维护
-
-### Regular Tasks / 定期任务
-- [ ] Review and update Actions monthly
-- [ ] Audit workflow permissions quarterly
-- [ ] Review and update deny.toml
-- [ ] Check for deprecated lints in clippy.toml
-- [ ] Update Rust toolchain versions
-- [ ] Review and optimize cache strategies
-- [ ] Clean up old workflow runs
+- ✅ Path filters (`paths`/`paths-ignore`) to skip unnecessary runs
+- ✅ `concurrency` to cancel superseded runs (saves minutes)
+- ✅ `timeout-minutes` on every job (prevents runaway runners)
+- ✅ Minimal `permissions` (`contents: read` default)
+- ✅ Third-party actions pinned to major versions
+- ✅ `Swatinem/rust-cache@v2` for reliable smart caching across all jobs
+- ✅ `actions/checkout@v6` everywhere (improved credential safety)
+
+### Recommended Next Steps / 推荐的后续步骤
+1. **Cross-platform matrix** (macOS/Windows) — adds CI cost but catches platform bugs
+2. Widen clippy/test to `--all-targets` once the runtime-fix branch merges
+3. GitHub Environments for release protection
+4. Branch protection rules requiring status checks to merge
+5. `CODEOWNERS` file for automatic review requests
+6. Signed commits for releases

+//! io_uring reactor 后端(仅 Linux,feature `io-uring`)。
+//!
+//! **Status: reserved / not yet implemented.**
+//! **状态:预留 / 尚未实现。**
+//!
+//! This module is the integration point for a future high-performance
+//! thread-per-core io_uring reactor, modeled after [monoio]. When the
+//! `io-uring` feature is active on Linux, `Runtime::with_config` should prefer
+//! an [`IoUringDriver`] over the default `async-io` reactor.
+//!
+//! 此模块是未来高性能 thread-per-core io_uring reactor 的接入点,参考 [monoio]
+//! 建模。当 `io-uring` feature 在 Linux 上激活时,`Runtime::with_config` 应优先
+//! 选用 [`IoUringDriver`] 而非默认的 `async-io` reactor。
+//!
+//! # Why io_uring? / 为何用 io_uring?
+//!
+//! io_uring delivers true zero-syscall-storm async I/O: submissions and
+//! completions are batched in shared ring buffers, eliminating the per-call
+//! `epoll_wait`/`read`/`write` syscalls. Combined with thread-per-core (no
+//! cross-thread work stealing), this is the lowest-latency async model on
+//! Linux. See <https://kernel.dk/io_uring.pdf> and the monoio architecture.
+//!
+//! io_uring 提供真正的零系统调用风暴异步 I/O:提交与完成在共享环形缓冲区中
+//! 批处理,消除每次调用的 `epoll_wait`/`read`/`write` 系统调用。配合
+//! thread-per-core（无跨线程 work stealing),这是 Linux 上最低延迟的异步模型。
+//! 见 <https://kernel.dk/io_uring.pdf> 及 monoio 架构。
+//!
+//! # Implementation plan / 实现计划
+//!
+//! 1. Add `io-uring = "0.7"` under `[target.'cfg(target_os = "linux")'.dependencies]` (gated by the
+//!    `io-uring` feature) in `Cargo.toml`.
+//! 2. Implement `IoUringDriver` here: a `Driver`-equivalent that owns an `io_uring::IoUring`
+//!    instance, registers FDs as `SubmissionQueuee`s, and drains the completion queue into wakers —
+//!    mirroring `async-io`'s `Reactor::react()` but with ring buffers instead of epoll.
+//! 3. In `runtime.rs`, add `#[cfg(all(target_os="linux", feature="io-uring"))]` selection logic in
+//!    `Runtime::with_config` to build an `IoUringDriver` instead of relying on `async-io`.
+//! 4. The `async-net` I/O types would need io_uring-aware equivalents (or use `monoio`'s net
+//!    types), since async-net is bound to the async-io reactor.
+//!
+//! # Why this is deferred / 为何暂缓
+//!
+//! This requires a Linux environment to build, run, and benchmark. On macOS
+//! (the current dev platform) io_uring does not exist, so the implementation
+//! cannot be validated here. The reservation (feature flag + this module) lets
+//! a Linux contributor pick up the work with a clear integration point.
+//!
+//! 这需要 Linux 环境来构建、运行与基准测试。在 macOS（当前开发平台）上
+//! io_uring 不存在,故实现无法在此验证。此预留（feature flag + 本模块）使
+//! Linux 贡献者可在明确的接入点继续该项工作。

-//! `hiver-runtime` provides a high-performance async runtime based on io-uring

+//! `hiver-runtime` builds on the [`async-executor`] + [`async-io`] + [`async-net`]
+//! ecosystem (the same crates `smol` is composed of): a multi-task executor driven
+//! by a reactor-aware `block_on`, with cross-platform epoll/kqueue/IOCP I/O.
+//! This keeps the public surface stable (`Runtime`, `block_on`, `spawn`,
+//! `io::*`, `time::*`) while delegating the low-level scheduling and I/O to
+//! battle-tested libraries.

-//! Task management module
-//! 任务管理模块
+//! Task module
+//! 任务模块
 //!
-//! # Overview / 概述
+//! Provides the task spawning and joining primitives. In the
+//! async-executor/async-io backend, `spawn` submits to the runtime's
+//! [`async_executor::Executor`] (reached via [`crate::runtime::Handle`]) and
+//! returns a [`JoinHandle`] that wraps the [`async_executor::Task`].
+//! Fire-and-forget semantics are supported via [`JoinHandle::Drop`], which
+//! detaches the underlying task so it keeps running when the handle is
+//! dropped without being awaited.
 //!
-//! This module provides task spawning and management with support for:
-//! - Task lifecycle tracking (Running, Completed, Cancelled)
-//! - Wake-up notifications for async polling
-//! - Join handles for awaiting task completion
-//!
-//! 本模块提供任务生成和管理，支持：
-//! - 任务生命周期跟踪（运行中、已完成、已取消）
-//! - 异步轮询的唤醒通知
-//! - 等待任务完成的join句柄
-
-#![allow(private_interfaces)]
+//! 提供任务 spawn 与 join 原语。在 async-executor/async-io 后端,`spawn` 将任务
+//! 提交到 runtime 的 [`async_executor::Executor`]（经 [`crate::runtime::Handle`]
+//! 访问）,并返回包裹 [`async_executor::Task`] 的 [`JoinHandle`]。
+//! fire-and-forget 语义经由 [`JoinHandle::Drop`] 支持 —— 它 detach 底层任务,
+//! 使句柄在未被 await 即丢弃时任务仍继续运行。

 //! Timer module
 //! 定时器模块
 //!
-//! # Overview / 概述
+//! Provides async timers backed by [`async_io::Timer`], driven by the same
+//! `async-io` reactor that [`crate::Runtime::block_on`] polls. This replaces
+//! the former self-built hierarchical timing wheel, which required a dedicated
+//! `advance_timers()` step in `block_on` — that step no longer runs in the
+//! async-executor/async-io backend, so the wheel-based timers would never wake.
 //!
-//! This module provides efficient timer management using a hierarchical timing wheel.
-//! The timing wheel provides O(1) insertion, deletion, and advancement.
-//!
-//! 本模块使用分层时间轮提供高效的定时器管理。
-//! 时间轮提供O(1)插入、删除和推进操作。
-//!
-//! # Timer Wheel Algorithm / 时间轮算法
-//!
-//! The timer wheel is organized as a hierarchy of wheels with different granularities:
-//! - Wheel 0: 1ms resolution, 256 slots (256ms range)
-//! - Wheel 1: 256ms resolution, 64 slots (16.384s range)
-//! - Wheel 2: 16.384s resolution, 64 slots (1048.576s range)
-//! - Wheel 3: 1048.576s resolution, 64 slots (67108.864s range)
-//!
-//! 时间轮组织为具有不同粒度的层级：
-//! - 轮0：1ms分辨率，256个槽（256ms范围）
-//! - 轮1：256ms分辨率，64个槽（16.384s范围）
-//! - 轮2：16.384s分辨率，64个槽（1048.576s范围）
-//! - 轮3：1048.576s分辨率，64个槽（67108.864s范围）
-//!
-//! # Example / 示例
-//!
-//! ```rust,no_run,ignore
-//! use hiver_runtime::time::{sleep, Duration};
-//!
-//! async fn example() {
-//!     sleep(Duration::from_millis(100)).await;
-//!     println!("Woke up after 100ms");
-//! }
-//! ```
+//! 提供基于 [`async_io::Timer`] 的异步定时器,由 [`crate::Runtime::block_on`]
+//! 轮询的同一 `async-io` reactor 驱动。这替代了原先自研的分层时间轮 —— 后者
+//! 需要 `block_on` 中专用的 `advance_timers()` 步骤,而该步骤在
+//! async-executor/async-io 后端中不再运行,故基于时间轮的定时器永不会唤醒。

+//! Before the waker fix, `AcceptFuture`/`ReadFuture` returned `Poll::Pending`
