+# 业务基础模块
+
+这批能力位于 main，尚未包含在 `v0.6.0-preview` 标签中。统一示例见
+[examples/modules](examples/modules/README.md)。业务入口继续使用 `omni.New`，中间件依赖
+`httpx`，不依赖具体服务端网络实现。各模块按需创建、注入 Service，再注册到应用关闭流程。
+
+## 缓存：cache 与 cache/redis
+
+```go
+store, err := cache.NewMemory(cache.MemoryConfig{MaxEntries: 4096, MaxBytes: 32 << 20})
+if err != nil { return err }
+application.OnShutdown(store.Close)
+loader, err := cache.NewLoader(store, cache.LoaderConfig{MaxLoads: 128, Timeout: 5 * time.Second})
+if err != nil { return err }
+value, err := loader.GetOrLoad(ctx, "tenant:42:product:7", time.Minute,
+    func(ctx context.Context) ([]byte, error) { return repository.LoadProduct(ctx, "42", "7") })
+```
+
+- `Store` 统一 `Get/Set/Delete`，返回字节切片；业务可用 JSON 编解码。
+- 内存缓存使用 LRU，同时限制条目数和 key/value 总字节数；字节上限不包含 Go 对象开销。
+  读写复制切片，过期时懒清理，没有每个条目一个 goroutine。
+- TTL 为零表示不过期，负值拒绝；缺失返回 `cache.ErrMiss`。删除不存在的 key 成功。
+- Loader 合并**同进程、同 key**的并发回源，最多同时运行 `MaxLoads` 个不同 key 的加载。
+  单个调用者取消只停止等待；共享加载有独立超时，加载函数必须响应 context。
+  超限返回 `ErrBusy`，缓存故障直接返回错误，不自动当成 miss 冲击数据库。
+- 同 key 的调用必须具有相同数据含义、权限范围和 TTL；加载采用首个调用者的 context 值。
+  多租户 key 必须含租户标识。进程间合并、分布式锁、缓存更新与数据库事务一致性由业务另外设计。
+
+Redis 适配器借用调用方创建的 go-redis 客户端和连接池：
+
+```go
+client := goredis.NewClient(&goredis.Options{
+    Addr: "127.0.0.1:6379", PoolSize: 16, MaxRetries: -1,
+    DialTimeout: time.Second, ReadTimeout: time.Second,
+    WriteTimeout: time.Second, PoolTimeout: time.Second,
+    ContextTimeoutEnabled: true,
+})
+// 启动时先使用有截止时间的 context 执行 client.Ping(ctx)。
+store, err := rediscache.New(client, "billing:") // cache/redis 的导入别名
+if err != nil { _ = client.Close(); return err }
+application.OnShutdown(client.Close)
+// store 可直接传入 cache.NewLoader。
+```
+
+连接失败与 Redis 错误保持原样；只有 Redis nil 映射为 `ErrMiss`。Redis TTL 精度为毫秒，
+正的亚毫秒 TTL 提升到 1ms。适配器不负责关闭借用的客户端，Redis 服务端容量策略由部署配置。
+连接池和超时配置参考 [go-redis 官方生产使用说明](https://redis.io/docs/latest/develop/clients/go/produsage/)。
+
+## 出站 HTTP：httpc
+
+```go
+client, err := httpc.New(httpc.Config{
+    Timeout: 3*time.Second, MaxRetries: 2, MaxConnsPerHost: 32,
+    MaxResponseBytes: 1 << 20,
+})
+if err != nil { return err }
+application.OnShutdown(client.Close)
+err = client.JSON(ctx, "GET", serviceURL, nil, &result)
+```
+
+客户端应在服务启动时创建并复用。默认使用独立的 `net/http.Transport` 连接池，每个目标主机
+有连接上限；该上限不是整个进程的全局连接数上限。也可以注入自有 `http.RoundTripper`，
+其连接限制和生命周期由调用方负责。这样出站实现同样可以替换。
+
+总超时覆盖建连、重试、等待和读取响应体。`Do` 返回后调用方必须读取/关闭 `response.Body`；
+`JSON` 自动关闭，并限制解码前读取的字节数。`Do` 允许流式读取，本身不限制响应体大小。
+`Close` 拒绝新请求、关闭自有池的空闲连接；在途请求应先排空。
+
+`MaxRetries` 默认 0，最多 5。封装只对可重放的 GET/HEAD/OPTIONS 重试网络错误及
+429/502/503/504；POST/PUT/PATCH/DELETE 不做应用层自动重试。标准库 Transport 和借用的
+RoundTripper 自身的重放规则仍生效，不能据此承诺“只执行一次”。退避带抖动，尊重
+`Retry-After`；服务器要求等待超过 `MaxBackoff` 时直接返回该响应，不提前重试。
+重定向交给业务处理，3xx 不会自动跟随。
+
+默认从 context 传递 `X-Request-ID`，日志只包含方法、主机、状态、尝试次数和收到响应头的耗时，
+不记录完整 URL、查询参数、凭证和响应体。非 2xx 的 JSON 调用返回只带状态码的 `StatusError`。
+
+## 请求保护：middleware
+
+```go
+limiter, err := middleware.NewRateLimiter(middleware.RateLimitConfig{Rate: 20, Burst: 40})
+if err != nil { return err }
+idempotency, err := middleware.NewIdempotency(middleware.IdempotencyConfig{
+    Scope: func(c *httpx.Context) (string, error) {
+        principal, _ := auth.FromContext(c)
+        return principal.UserID, nil // 多租户应用应组合租户和用户 ID
+    },
+})
+if err != nil { return err }
+api := application.Group("/api", middleware.Timeout(3*time.Second),
+    auth.RequireAuth(authenticator), limiter.Middleware())
+api.POST("/orders", createOrder, idempotency.Middleware())
+```
+
+限流为进程内令牌桶，`Rate` 为每秒额度，`Burst` 为突发容量。默认按已解析的可信客户端 IP，
+可用 `Key` 按已认证身份分桶。额度不足返回 **429 + Retry-After**；key 数超过 `MaxKeys`
+返回 **503**。满容量时不会踢掉活跃桶让攻击者绕过限流；空闲桶经过完整补充周期后才允许回收。
+
+Timeout 设置协作式 deadline，不额外启动 Handler goroutine。业务及下游调用必须响应 context；
+超时后尚未提交响应时返回 **504**，已经提交的响应保持原状态。它不能强制中断任意 Go 代码，
+也不能替代网络层读写超时。不要在业务代码中异步持有 `httpx.Context`。
+
+幂等保护适用于小型、非流式写接口：
+
+- 必须先认证/鉴权，再执行幂等中间件；`Scope` 必须取自服务端验证过的身份。
+  GET/HEAD/OPTIONS 直接通过，写请求要求 `Idempotency-Key`，长度 1..128 个非空格 ASCII 字符。
+- 同 Scope + key + 方法/URL/Content-Type/body 重放首次响应；内容改变返回 **409**。
+  正在执行或结果不可重放的相同请求也返回 **409**，不并发执行第二次。
+- 默认最多 32 个处理中请求、256 条记录、16 MiB 保存的响应头/body，单次请求体 1 MiB、
+  响应 body 64 KiB。请求超限 **413**，容量满 **503**，响应超限 **500**。
+- panic、5xx、超时、响应超限、Set-Cookie、Cache-Control:no-store 或保存容量不足时保留失败记录，
+  阻止在 TTL 内自动重执行业务。业务可能已经提交，调用方应查询实际结果后处理。
+- 完成记录默认保留 10 分钟；在途记录不会因 TTL 到期而允许重复执行。
+  重放保留原响应 body、原 `requestId` 与原 `X-Request-ID`，增加 `Idempotency-Replayed:true`；
+  本次访问日志仍使用本次请求 ID。
+- 记录仅在当前进程有效，重启、TTL 到期和多副本切换后均无法保证去重。支付、库存等关键写入
+  应在数据库事务内配合唯一业务键。该实现不提供跨进程 exactly-once，也不支持 SSE/流式/升级连接。
+
+## 后台执行：task
+
+```go
+jobs, err := task.New(task.Config{Workers: 4, QueueSize: 128, TaskTimeout: 30*time.Second})
+if err != nil { return err }
+application.OnShutdown(jobs.Close) // 在注册数据库/缓存关闭之后注册，先排空任务
+future, err := jobs.Submit(serviceContext, "refreshCatalog", refreshCatalog)
+if err != nil { return err } // 满队列立即返回 ErrQueueFull
+err = future.Wait(ctx)       // 可选；不等待时，任务失败仍通过 OnError/logx 报告
+err = jobs.Every("refreshCatalog", time.Minute, refreshCatalog)
+```
+
+固定 worker 和有界队列控制资源。任务保留提交 context；需要独立于 HTTP 请求执行时使用服务
+context，或明确使用 `context.WithoutCancel` 保留日志关联值。任务仍受 Runner 的超时/退出控制。
+任务函数与 `OnError` 回调应及时返回，尤其要响应取消；panic 被转为失败，worker 继续工作。
+
+`Every` 使用固定间隔，第一次在一个间隔后执行；同一计划上轮尚未完成、排队或队列满时跳过。
+默认最多 128 个计划，名称不可重复。`Stats` 提供 active/queued/completed/failed/skipped。
+它是进程内任务执行器，没有任务持久化、失败自动重试、cron 表达式、跨副本选主或崩溃恢复。
+
+`Shutdown(ctx)` 停止接收和调度，排空已接受任务；截止时间到后取消任务并及时返回。
+忽略取消的任务不能被 Go 强杀，可能继续运行。`Close` 默认给排空 10 秒。
+
+## 增加业务模块：go-omni add
+
+```sh
+go build -o /tmp/go-omni ./cmd/go-omni
+/tmp/go-omni add orderItems --dir /path/to/billing
+```
+
+生成 `internal/orderItems/{module.go,model,repository,service,handler,README.md}`，包含 name/createdAt
+示例模型、内存 CRUD、输入校验、错误映射及可注入 Repository。模块名使用 lowerCamelCase。
+
+在现有启动代码中导入模块后调用 `orderItems.Register(application, repository, authMiddleware)`。
+脚手架不自动修改现有路由、main、go.mod 或数据库，已有目录不会覆盖。
+内存 Repository 仅为可运行示例：重启丢数据，列表未分页；正式业务应实现自己的持久化 Repository。
+
+## 验证入口
+
+```sh
+GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race ./...
+go vet ./...
+go build ./...
+python3 scripts/verifyModules.py --goproxy https://goproxy.cn,direct
+```
+
+Linux runner 顺序运行两个容器：全量 race/vet/build/独立生成项目，随后真实 Redis 适配验证。
+每次最多一个容器，限制 2 CPU、2 GiB（不额外使用 swap）、256 pids；Redis 测试容器禁外网，
+只用内部 loopback，不发布端口。Redis 集成二进制为静态非 race，适配器单测在全量 race 中覆盖。
+结束清理本轮容器，并记录提交、源文件摘要、镜像 ID、日志摘要和原有容器是否仍运行。
+
+本轮通过结果和原始证据见 [业务模块验收](performance/modulesAcceptance.md)。

 `transport/native` 当前支持 HTTP/1.1、Keep-Alive、`Content-Length` 和 chunked 请求体、`http.Flusher` 流式响应、可选 TLS、读写超时和优雅关闭；不支持的传输编码会被拒绝。它会复用连接状态和响应对象，并可通过 `MaxConnections`、`MaxConcurrentRequests` 限制内存峰值。它仍通过标准 HTTP 请求/响应接口连接业务层，适合在现有 Handler / Service 上做网络层验证。

 - 标准库与 native 共用 TCP benchmark，固定 1 / 32 / 128 并发；相同应用、客户端、超时和响应检查，避免两个测试入口逐渐失去可比性。
 - 新增独立服务进程压测 `internal/perfcheck`，记录成功吞吐、P50/P95/P99、服务端分配、采样堆峰值，以及 128 / 1,024 条空闲长连接的堆内存、goroutine 和断开后的回收情况。原始报告保存在 `performance/tcpBaseline.json`。
 - native 已支持受 `MaxBodyBytes` 约束的 `Content-Length` / chunked 请求体，仍使用标准 `http.Request` / `http.ResponseWriter` 作为桥接；解析器、连接抽象和生产压测将在后续阶段继续下沉。
+- native 请求体已改为流式读取，Handler 可边到边处理，服务端只在 Handler 返回后排空剩余 body，超时、畸形和超限 body 会取消请求并关闭连接。
 - native 响应已支持标准 `http.Flusher`；HTTP/1.1 流式响应使用 chunked framing，普通响应继续走 `Content-Length`，HTTP/1.0 回退到关闭连接分帧。
 - native 长请求已补客户端断开及流式写失败取消，监测退出后再复用 Reader；已验收普通/流式断开、慢 Handler 后连续 Keep-Alive 和管线数据不被误消费。短请求延迟启动监测，已有管线数据时取消依赖后续写失败或 Handler 返回。
 - 已补充慢请求头、慢 Content-Length body、慢 chunked body、慢 TLS 握手、大请求体、HTTP/1.0 Keep-Alive、HEAD/204 和管线请求验收；Linux/arm64 容器已通过全量 race、vet、build，以及 3 秒 TLS 并发/空闲连接矩阵。原始报告见 [tlsBaselineLinux.json](performance/tlsBaselineLinux.json)。
 - 已验证 `MaxConnections` 满载时快速拒绝新连接、请求完成后释放容量；后续仍需在目标部署环境观察文件描述符、内核 socket 缓冲和反向代理联动。
+- 已验证 `MaxConcurrentRequests` 满载返回 503，活动请求结束后槽位释放，后续请求可以恢复处理。
+- native `Stats()` 已记录连接和请求过载拒绝数；访问日志已支持可信代理网段配置，默认拒绝伪造的 `X-Forwarded-For`。
+- native TLS 已明确只宣告 HTTP/1.1 ALPN；HTTP/2 暂由边缘代理终止或使用 `transport/nethttp`，已整理独立协议设计、流控和压测门槛，见 [native HTTP/2 进入条件](transport/native/HTTP2.md)，完成后再接入 native。
+- 已加入独立 `transport/http2` 实验 Runner，验证 h2c/TLS h2、连接上限、全局请求并发拒绝和恢复，以及 GOAWAY 排空、RST_STREAM 单流取消和服务关闭超时；它使用 `x/net/http2` 作为临时帧/流控实现，已完成下述 Nginx HTTP/2 回源联调，尚未接入 native 默认路径。
+- HTTP/2 实验已补齐头部/请求体上限、128 路同连接多路复用、慢读取流控、协议错误、RST_STREAM 与 GOAWAY 统计，并提供 `scripts/verifyHTTP2.py --duration 30m` 的 Linux TLS 长测入口；长测默认不启用 race，短时并发检查使用 `--race`（默认 60 秒）。测试容器默认限制为 2 核、2 GiB 内存、256 个进程/线程，并设总时限和退出清理；受限长测和 Nginx 回源联调结果见下方。
+- 新 Linux amd64 环境在上述硬上限内完成 HTTP/2 普通模式 2 分钟与 race 模式 60 秒短测，分别为 3,885,273 和 377,788 次请求，均为 0 失败；连接/请求归零、FD 回到基线。SIGTERM、SIGHUP 和总时限退出清理已实测。报告见 [HTTP/2 短测记录](performance/http2SmokeLinux.json)；此前无资源上限的 race 长测因 RSS 增长而停止，不作为通过依据。
+- 已完成受限的 HTTP/2 单连接 TLS 30 分钟长测：128 个 worker、58,102,476 次请求、0 失败及协议错误；包含客户端与服务端的采样 RSS 峰值约 22.6 MiB，连接/活动请求归零，FD 由 9 回到 6。120 份定时采样见 [HTTP/2 长测报告](performance/http2SoakLinux.json)，测试提交和原始日志校验值保存在报告中。Nginx HTTP/2 回源的 GOAWAY/排空结果见下方。
+- 已完成 8 条 TLS 连接、128 个 worker 的 30 分钟混合长测：53,079,128 次普通请求、106,971 次慢上传、5,588 次慢下载，0 失败及协议错误。采样 RSS 峰值约 116.6 MiB（包含客户端和服务端），前段与最后 5 分钟 RSS 中位数分别约 111.3/110.4 MiB；退出后活动连接/请求归零，goroutine 2、FD 6 均回到基线，两次 GC 后存活堆约 450 KiB。原始日志、120 份采样、测试提交和校验值见 [混合长测报告](performance/http2MixedSoakLinux.json)。
+- 已补连接级窗口耗尽时的暂停、同连接 204/跨连接隔离、WINDOW_UPDATE 恢复和连接复用；已补零窗口写阻塞在关闭超时后的解除阻塞、请求取消与回收。Linux amd64 的 HTTP/2 全包 race、vet、build 已通过，见 [边界回归报告](performance/http2FlowControlLinux.json)。
+- 新增 HTTP/2 零 stream 窗口时的慢响应隔离、WINDOW_UPDATE 恢复、RST_STREAM 取消与请求槽位回收测试；补充 TLS 半开握手占满连接上限时的及时拒绝、超时回收及正常请求恢复测试。
+- 已完成 Nginx 1.30.5 → HTTP/2 的 TLS 回源联调：普通与 race 模式各 3 轮，共 18 个子场景通过；覆盖两段证书校验、32 次 POST 复用一条回源连接、不可信 CA/主机名拒绝、504 超时、客户端取消、GOAWAY 后旧 POST 完成及 20 个新 POST 转入新实例，无重复业务执行。见 [验收说明与报告](transport/http2/PROXY.md)。
+- `scripts/verifyHTTP2Proxy.py` 顺序运行受限编译容器和禁用外部网络的测试容器；总时限、SIGTERM、SIGHUP 清理已在 Linux 实测，原有 7 个业务容器仍运行。当前结果不覆盖 Nginx master/worker 重载或 Cloudflare 实网部署。
+- 已接入 `omni.New` 的统一 transport / TLS / shutdownTimeout 配置：默认 nethttp，可显式选择 native 或实验 HTTP/2；证书在监听前加载，HTTP/2 配置必须启用 TLS。`RunWith` 继续支持自定义网络层，业务不依赖具体适配器。
+- 参考业务已增加五种真实 TCP/TLS 组合的 CRUD、认证权限、错误响应、requestId 日志与协议协商测试；三种适配器共用排空和超时退出测试。修复 native 退出时过早取消在途请求，并使关闭超时错误返回调用方。下一步仍为业务环境试用、native 多协议监听器设计与接入回归，HTTP/2 保持实验状态。
+- 统一启动已通过 Linux 全仓库 race/vet/build 及关键场景 10 次重复验证；修复了重复测试发现的 native 活动连接转为空闲时错过关闭的竞态，并保证不响应取消的 Handler 不阻塞关闭超时返回。脚手架独立项目的 native SIGINT/SIGTERM 验证通过；失败复现与最终验收证据见 [统一启动验收](performance/transportStartup.md)。
 - 已用 16 个并发 worker 完成 3,200 次建连/断连 race 验收；MaxConnections 满载拒绝、槽位释放和 TLS 连接上限均已覆盖。
 - 新增 `scripts/verifyLinux.py`，固定在 Go 1.25 Linux 容器内运行 race、vet、build 和可选 TLS/非 TLS perfcheck；perfcheck 记录堆、goroutine、连接和 Linux 文件描述符。
 - Linux/arm64 已完成 30 秒、128 并发、512 空闲连接的 TLS 与非 TLS 持续回归，报告见 `performance/linuxSoak.json` 和 `performance/linuxSoakTLS.json`，均为 0 错误且连接、goroutine、FD 回收正常。
-- 自动验收入口：`python3 scripts/verifyPerformance.py`；Linux 固定验收入口：`python3 scripts/verifyLinux.py --load --tls --duration 30m`。真实部署仍需按目标代理和内核参数执行 30 分钟发布前压测。
+- 目标 Linux amd64 服务器已完成 30 分钟、128 并发、512 空闲连接的 TLS 验收：net/http 约 11,865 req/s、native 约 13,098 req/s，均为 0 错误；native P95/P99 为 44.040/52.429 ms，空闲连接堆增量约 4.50 MiB，FD 由 7 增至 519 后回到 7。
+- 新增 `scripts/verifyProxy.py`，在 Linux Docker 中用 Nginx 反向代理 native TLS 服务，检查真实 TLS、Keep-Alive、上游超时和 native 优雅关闭。
+- 自动验收入口：`python3 scripts/verifyPerformance.py`；Linux 固定验收入口：`python3 scripts/verifyLinux.py --load --tls --duration 30m`；代理联调入口：`python3 scripts/verifyProxy.py`。
+
+## 6. 可复用业务基础模块（第一版）
+
+- `cache`：有界 LRU 内存缓存、TTL、数据复制、同进程合并回源；`cache/redis` 适配 go-redis 客户端，保留借用连接池的生命周期边界。
+- `httpc`：复用出站连接、每目标主机连接上限、覆盖响应体的总超时、保守重试、requestId 传递、JSON 响应大小限制与安全日志字段。
+- `middleware`：有容量上限的令牌桶限流；按已认证身份隔离的幂等保护，覆盖冲突、处理中记录、失败记录、容量与请求/响应大小上限；协作式请求 deadline。
+- `task`：固定 worker、有界队列、任务超时、panic 隔离、间隔调度、不重叠执行、停止接收与排空/取消。
+- `go-omni add`：向已有项目生成 Handler / Service / Repository / Model 和模块注册入口；目标存在时拒绝覆盖，默认内存 CRUD 可注入持久化 Repository。
+- `examples/modules` 将以上运行时能力串联，使用真实 TLS 在 nethttp、native、实验 HTTP/2 下验证缓存、出站 requestId、认证、幂等、后台任务与退出。
+- 使用文档：[业务基础模块](MODULES.md)。验证入口：`GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race ./...` 和 `python3 scripts/verifyModules.py`；Linux runner 顺序运行全量检查及独立 Redis 容器，硬限制 2 CPU / 2 GiB / 256 pids。
+- 最终代码已通过 Linux amd64 全仓库 race/vet/build、独立生成项目 CRUD、真实 Redis 7.4.11 与三种网络层 TLS 组合测试；测试容器清理完成、原有 7 个业务容器仍运行。提交、源码摘要与完整输出见 [验收记录](performance/modulesAcceptance.md)。
+- 当前幂等、限流、任务调度和合并回源均为单进程能力；Redis 仅提供缓存存储，不代表已实现分布式去重、任务持久化或跨副本选主。eTax 指定业务模块接入依用户要求暂缓。
 
 以上阶段以验收结果判断完成。当前仍是基础框架试用阶段；MySQL、适配层契约和一次业务模块试用已完成，自研网络层已有可运行预览，稳定性与生产规模验证尚未完成。

+# 业务基础模块验收
+
+2026-09-23，第一版功能验收通过。运行时代码提交：
+`b9259e628e84a4e1cc3a73801b04dd864c4f3a19`。
+使用方式与限制见 [MODULES.md](../MODULES.md)。
+
+| 能力 | 验收内容 |
+| --- | --- |
+| cache | 字节切片所有权、LRU/容量、TTL 边界、取消/关闭、并发合并加载、独立等待取消、加载容量/超时/panic、存储故障不触发回源 |
+| cache/redis | 真实 Redis 二进制值读写、TTL 到期、零 TTL 持久、删除、WRONGTYPE 错误保留、取消写入不落库、关闭客户端错误不被当成 miss |
+| httpc | TCP 连接复用、GET 503 重试、POST/不可重放 body 不做应用层重试、总超时覆盖退避与响应体、响应大小、禁止自动重定向、请求 ID、提前拒绝时关闭请求体 |
+| middleware | 并发限流额度、补充与过期、429/503、504 和已提交响应；身份隔离、精确响应重放、内容冲突、在途记录不随 TTL 过期、失败/panic/超限记录、容量拒绝与超时组合 |
+| task | worker/队列上限、panic 隔离、正常排空、超时取消、队列任务不在强制关闭后启动、间隔任务不重叠、跳过统计 |
+| go-omni add | 模块命名/路径校验、符号链接拒绝、已有文件保护、独立消费项目编译和完整 CRUD、认证/校验/取消 |
+| 组合运行 | 同一示例在 nethttp/native/实验 HTTP/2 的真实 TLS 下验证：合并缓存、上游请求 ID、幂等重放、认证不可绕过、任务只提交一次和退出 |
+
+macOS arm64 / Go 1.27.1 完成主体提交的全仓库 race、vet、build 与独立生成项目测试；
+最后的 HTTP 客户端请求体关闭修补另行通过 httpc race/vet。
+
+Linux amd64 / Go 1.25.14 对上述最终运行时代码提交重新执行并通过：
+
+```sh
+GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race -count=1 -timeout=240s ./...
+go vet ./...
+go build ./...
+```
+
+随后使用 Redis 7.4.11 执行真实集成测试。Redis 测试二进制静态编译、未启用 race，
+适配器单元测试包含在前一阶段的全量 race 检查中。生成项目使用本地 replace 验证当前源码，
+本轮不包含新版本标签发布或远程 CLI 安装验收。
+
+可复现入口：
+
+```sh
+python3 scripts/verifyModules.py --goproxy https://goproxy.cn,direct
+```
+
+两阶段容器顺序运行，单容器限制 2 CPU / 2 GiB 内存及内存+swap / 256 pids，
+总时限 900 秒；本次约 155 秒完成。Redis 容器以非 root 身份运行，禁外网、根文件系统只读，
+只使用内部 loopback，未发布端口。结束确认两个测试容器清理完毕，原有 7 个业务容器均仍运行。
+
+原始证据：[结构化报告](modulesLinux.json)、[完整日志](modulesLinux.txt)。
+报告记录提交、各源码 SHA-256、镜像 ID、命令、资源上限和日志摘要，已与本地文件逐项核对。
+报告中的工作区状态仅为上一轮生成的两个未跟踪验收文件，没有未提交的运行时代码。
+
+测试期间修正了任务池取消回调尚未执行时任务结果误报成功的竞态，
+以及幂等缓冲链未提交响应时 deadline 应交给外层 Timeout 返回 504 的组合行为。
+
+这是功能与并发正确性验收，不是生产吞吐或跨副本一致性验收。当前限流、幂等、调度与合并回源
+是单进程能力；请求/任务超时依赖业务配合取消。native 和 HTTP/2 的成熟度沿用各自原有定义。

+# 统一启动配置与业务接入验收
+
+2026-09-23，代码提交 `be620d2243ff85288f0afc44689c2e46abd714ec`。
+
+`omni.New(omni.WithConfig(settings))` 现在通过 `Run`、`RunContext` 或 `ServeContext`
+统一选择 nethttp、native 或实验 HTTP/2，加载 TLS 证书，并应用退出等待时间。
+默认仍是 nethttp；HTTP/2 必须显式选择并配置 TLS，native 仍只支持 HTTP/1.1。
+`RunWith` 继续支持自定义 Runner，由 Runner 管理自己的 TLS、超时及其他网络参数。
+
+## 验证范围
+
+| 场景 | 检查 |
+| --- | --- |
+| nethttp / native 明文；nethttp / native / HTTP2 TLS | 参考业务通过真实 TCP 执行 CRUD、分页、认证权限、参数错误、冲突和 404；校验响应及日志 requestId |
+| 三种 TLS 启动 | 使用临时受信任证书，验证证书链及 ALPN；nethttp、HTTP2 为 h2，native 为 http/1.1 |
+| 配置错误 | 未知适配器、HTTP2 缺 TLS、证书不配对、证书无法读取，在监听前失败且只清理一次 |
+| 已有 listener / 自定义 Runner | 配置失败或取消时关闭 listener；自定义 Runner 入口继续独立于内置适配器选择 |
+| 正常关闭 | 停止监听后，在途请求仍能成功完成，然后清理资源 |
+| 关闭超时 | 取消请求、关闭连接并返回超时；不响应取消的 Handler 不会无限阻塞框架返回 |
+| native 响应完成与关闭并发 | 在响应已经选择 Keep-Alive 后暂停写入，再触发关闭；响应写完后连接立即回收，退出无超时 |
+
+框架无法强制终止不响应取消的业务 goroutine。业务仍需处理 context 取消；每个 native Server
+只用于一次服务生命周期，重启时创建新实例，以免超时后的旧 Handler 与新实例混用。
+
+## Linux 结果
+
+Go 1.25.14、Linux amd64、`golang:1.25` 镜像的实际 image ID、完整命令与代码提交
+记录于 [通过报告](transportStartupLinux.json)，[原始输出](transportStartupLinux.txt) 的 SHA-256 已核对。
+
+- 全仓库 `go test -race -p 1 -count=1 -timeout=3m ./...`、`go vet -p 1 ./...`、`go build -p 1 ./...` 通过。
+- 上表的配置、TLS 业务、退出和 native 并发回收测试重复 10 次，全部通过。
+- 单个验证容器限制为 2 核、2 GiB 内存、同额 memory-swap（无额外 swap）、256 个进程/线程，GOMAXPROCS=2。
+- Docker inspect 已确认限制生效，代码只读挂载，没有发布端口；测试流量仅访问容器内 loopback。
+- 总时限 480 秒；完成后验证容器已删除，之前运行的 7 个业务容器仍在运行。
+
+首轮重复测试曾在 native 排空阶段失败，记录保留在
+[修复前报告](transportStartupBeforeFixLinux.json) 和 [修复前输出](transportStartupBeforeFixLinux.txt)。
+原因是响应写入和关闭并发时，连接转为空闲后可能再次等待 Keep-Alive 请求，直到关闭超时。
+新增暂停响应写入的确定性测试在修复前失败；修复将“转为空闲”和“判断是否关闭”置于同一临界区，
+最终报告包含修复后的重复回归。首轮失败不计作通过证据。
+
+## 本地与脚手架
+
+macOS arm64、Go 1.27.1 的全仓库 race、vet、build 通过；app/native 包额外重复 10 次 race 检查通过。
+实际生成的独立业务模块通过以下入口验证 native 启动、HTTP 请求、SIGINT / SIGTERM、退出码 0、
+端口关闭，以及 `omni.New().Run` 的资源清理回调：
+
+```sh
+go build -o /tmp/go-omni-startup-cli ./cmd/go-omni
+python3 scripts/verifyScaffold.py --cli /tmp/go-omni-startup-cli --framework-dir . --transport native
+```
+
+独立模块通过本地 replace 引用被测源码；这不表示旧的 `v0.6.0-preview` 发布标签已包含新增配置。
+本轮是功能、并发和生命周期验收，没有重新进行 30 分钟长测，也不代表 native 已合并 HTTP/2
+或已经在真实业务环境发布。下一步是业务试用及 native 多协议监听器的独立设计与验收。

 `transport/nethttp` 是当前内置的标准库路由实现。它提供一套可移植的路径、方法和错误回退规则；自研网络层可以直接实现同一个 `httpx.Router` 契约。
 
+`transport/http2` 是独立的 opt-in 实验 Runner，负责连接接入、TLS/ALPN、连接上限和全局请求背压，底层帧解析与 stream 流控暂由 `golang.org/x/net/http2` 提供。它不替换 `transport/native`，也不改变默认启动器；只有通过 `App.RunWith(ctx, http2.New(nil), address)` 显式启用才会运行。
+
 `transport/native` 是第一版自研 HTTP/1.1 服务端：它自己管理 TCP listener、连接、Keep-Alive、请求解析、响应写回和优雅关闭，再把请求交给现有 `http.Handler`。请求体支持 `Content-Length` 和 chunked，并统一受 `MaxBodyBytes` 限制；其他传输编码会被拒绝。它仍使用标准 `http.Request` / `http.ResponseWriter` 作为业务桥接，因此不会影响现有 Handler / Service。
 
+native 提供 `server.Stats()` 读取已接受连接数、连接拒绝数、当前连接数和当前请求数，适合和 `metrics.Metrics` 的业务请求指标一起采集；读取不会阻塞连接生命周期。`RejectedConnections` 统计连接闸门拒绝，`RejectedRequests` 统计并发请求闸门返回 503。
+
 业务 Handler 需要流式返回时可以断言 `http.Flusher` 并调用 `Flush()`；HTTP/1.1 会自动使用 chunked 响应，普通未 Flush 的响应仍自动生成 `Content-Length`。HTTP/1.0 没有 chunked framing，会退回到写完后关闭连接。
 
 Handler 运行超过约 5 ms 时，native 启动一次阻塞读取监测；读到 EOF 或连接错误会取消 `Request.Context()`，流式写入失败也会触发取消。Handler 返回后先停止监测，再复用连接和 Reader；普通短请求不会启动监测 goroutine。
 
 如果客户端提前发送了下一条请求，监测器会保留管线数据并退出，避免预读不断占用内存。这种情况下，断开取消会延后到写失败或 Handler 返回；业务仍应为下游调用设置自己的超时。
 
-服务端不是把连接交给一个全局串行 worker，而是每条连接独立处理请求；Keep-Alive 负责复用客户端连接，`Server` 内部的 `sync.Pool` 负责复用小型 Reader、响应对象和连接状态。Reader 默认只有 4 KiB，需要处理大请求头时按需增长。需要保护内存上限时，可以设置 `MaxConnections` 和 `MaxConcurrentRequests`；超出连接上限的连接会被关闭，超出请求并发上限的请求返回 503，不会无限排队。

 这个设计借鉴了 Nginx 的资源边界，但没有照搬它的进程模型：Nginx 用少量 worker 进程和事件机制管理大量连接，并用 `worker_connections` 限制每个 worker 的同时连接数；Go runtime 自己已经用 epoll / kqueue 等网络轮询器唤醒阻塞的 goroutine，因此 native 采用“accept loop + 每连接轻量 goroutine + 请求并发闸门”的等价实现。这样业务 Handler 可以继续执行同步代码，慢请求不会阻塞其他连接；只有在真实压测证明 goroutine 调度或协议状态机成为瓶颈时，才需要继续下沉为手写事件循环。

+# HTTP/2 代理回源验收
+
+本项验证的链路是：`Go HTTP/2 客户端 → TLS/h2 → Nginx → TLS/h2 → transport/http2`。客户端与回源两段分别检查协议、TLS 和请求内容；它使用真实 Nginx 进程及生成的测试证书。
+
+Nginx 的 `proxy_http_version 2` 从 1.29.4 起可用，见 [官方配置说明](https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_http_version)。本次固定使用 1.30.5。原有 `scripts/verifyProxy.py` 和 Nginx 1.27 环境继续用于 native HTTP/1.1 回源验收。
+
+## 运行
+
+在项目根目录执行：
+
+```sh
+python3 scripts/verifyHTTP2Proxy.py --count 3
+python3 scripts/verifyHTTP2Proxy.py --race --count 3 --output performance/http2ProxyRaceLinux.json
+```
+
+需要指定 Go 模块代理时追加 `--goproxy https://goproxy.cn,direct`。普通模式使用 `nginx:1.30.5-alpine`，race 模式使用 `nginx:1.30.5`，以提供 Go race 二进制需要的 glibc 运行环境；使用 `--nginx-image` 覆盖时需自行保持该兼容性。
+
+脚本先在 `golang:1.25` 中执行 vet 并编译测试二进制，清理编译容器后，再在 Nginx 镜像中执行测试。两个阶段顺序运行，每个容器固定限制为 2 核、2 GiB 内存、禁用 swap、256 个进程/线程。整个运行默认 600 秒总时限，单次测试进程还有 120 秒时限。
+
+集成测试容器使用 `--network none`、只读根文件系统和 128 MiB 临时内存目录，没有发布端口。客户端、Nginx 和新旧两个后端都只监听容器内回环地址。超时、SIGTERM、SIGHUP 会清理当前运行拥有的容器；检测到其他 HTTP/2 验收容器运行时，脚本会拒绝开始。
+
+## 验收内容
+
+| 场景 | 必须满足的结果 |
+| --- | --- |
+| 双段 TLS/h2 | 客户端验证代理证书；代理验证源服务器证书和主机名。业务 handler 必须看到 HTTP/2、ALPN h2 和预期 SNI。 |
+| 回源连接复用 | 32 次顺序 POST 仅建立 1 条回源 TLS 连接；每次校验独立 requestId、方法、请求体长度与 SHA-256。 |
+| 证书失败 | 不可信 CA 和错误主机名分别得到 502，均未进入业务 handler；正常路由随后仍可请求成功。 |
+| 超时 | 代理 250 ms 读取超时得到 504，后端请求 context 被取消、活动请求回到 0，后续请求恢复。 |
+| 客户端取消 | 客户端取消后，后端 handler 能退出并释放请求槽位，后续请求恢复。 |
+| GOAWAY 与新旧实例切换 | 旧实例保留一个处理中的 POST；开始 Shutdown 后必须观察到 GOAWAY。随后 20 个独立 POST 进入备用的新实例，旧 POST 释放后仍返回原实例的正确响应。旧实例最终连接/请求归零，业务执行无重复。 |
+
+新旧实例场景使用 Nginx primary/backup 上游与有限重试；测试没有开启 `non_idempotent` 重试。除了检查每次响应，还检查两个实例的实际 handler 次数及重复 requestId，避免重试掩盖重复执行。
+
+本次 Nginx 在超时和取消场景中关闭了相关回源连接，随后重新建连恢复；这里验收的是请求取消与资源回收，不要求代理必须通过 RST_STREAM 保留同一条回源连接。
+
+## 已有结果与边界
+
+2026-09-23，Linux amd64、Go 1.25.14、Nginx 1.30.5：普通模式和 race 模式各连续 3 轮全部通过，共 18 个子场景，无数据竞争。两轮运行后原有 7 个业务容器仍在运行。
+
+- [普通模式报告](../../performance/http2ProxyLinux.json) / [原始日志](../../performance/http2ProxyLinux.txt)
+- [race 报告](../../performance/http2ProxyRaceLinux.json) / [原始日志](../../performance/http2ProxyRaceLinux.txt)
+- [总时限、SIGTERM、SIGHUP 清理实测](../../performance/http2ProxyCleanupLinux.json)
+
+报告记录测试提交、源码 SHA-256、镜像 ID、完整执行命令、结果与日志校验值。它是功能联调，不是代理吞吐基准；使用单进程 Nginx 测试配置，验证后端实例切换，不覆盖 Nginx master/worker 配置重载、公网链路或 Cloudflare 实网部署。`transport/http2` 仍是独立实验适配器，native 的 HTTP/1.1 默认路径保持现状。

+# native HTTP/2 进入条件
+
+当前 `transport/native` 是经过 Linux 长连接和反向代理验收的 HTTP/1.1 实现。HTTP/2 暂不直接打开，原因是它把一个 TCP 连接变成多个独立请求流，连接级的 Keep-Alive、超时和并发限制不能直接复用现有 HTTP/1.1 状态机。
+
+当前已提供独立的 `transport/http2` 实验 Runner。它已经验证 TLS/h2、h2c、本地连接和请求闸门、GOAWAY 排空以及 RST_STREAM 取消；这些结果用于验证生命周期设计，不代表 native 已经启用 HTTP/2。实验 Runner 还覆盖了默认 1 MiB 头部上限、8 MiB 请求体上限、128 路同连接 stream 多路复用，以及 2 MiB 慢读取 body 在窗口耗尽后的恢复。`TestTLSSoak` 默认运行 3 秒，Linux 长测通过 `python3 scripts/verifyHTTP2.py --duration 30m` 启动。
+
+2026-09-23 已在 Linux amd64 完成单 TLS 连接、128 个 worker 的 30 分钟长测：58,102,476 次请求，0 失败与协议错误，采样 RSS 峰值约 22.6 MiB，退出后连接、活动请求和 FD 回收。测试容器限制为 2 核、2 GiB，测量包含同一进程中的客户端与服务端，见 [报告](../../performance/http2SoakLinux.json)。该场景包含慢 Handler 与 64 KiB body。
+
+同日完成多连接慢客户端混合场景：8 条独立 TLS 连接，每条 14 个普通请求 worker、1 个慢上传 worker、1 个慢下载 worker，持续 30 分钟。256 KiB 上传每 4 KiB 等待 2 ms；8 MiB 下载每次最多读取 64 KiB 后等待 20 ms。共完成 53,191,687 次请求，其中慢上传 106,971 次、慢下载 5,588 次，0 失败与协议错误；每条连接均覆盖三类请求且没有重连。采样 RSS 峰值约 116.6 MiB，包含客户端、服务端与下载缓冲；退出后活动连接/请求归零、goroutine 回到 2、FD 回到 6，释放测试数据并两次 GC 后存活堆约 450 KiB。运行命令为 `python3 scripts/verifyHTTP2.py --scenario mixed --duration 30m`，完整采样见 [混合长测报告](../../performance/http2MixedSoakLinux.json)。8 MiB 下载超过客户端的 stream 初始窗口，需要窗口更新，但不代表耗尽了连接级窗口；后者由下述独立帧测试验证。Nginx HTTP/2 回源联调结果见下方。
+
+连接级流控及关闭边界测试已通过 Linux amd64 的 HTTP/2 全包 race、vet、build 回归，测试提交、执行命令和原始日志校验值见 [边界回归报告](../../performance/http2FlowControlLinux.json)。
+
+Nginx 1.30.5 的真实 HTTP/2 回源联调也已通过：普通与 race 模式各 3 轮，覆盖两段 TLS/h2、证书拒绝、连接复用、超时/取消恢复和 GOAWAY 下的新旧实例切换。完整配置边界、运行方法与报告见 [HTTP/2 代理回源验收](../http2/PROXY.md)。
+
+## 目标边界
+
+- HTTP/2 必须作为显式 opt-in 协议，不改变 `omni.New()`、`transport/nethttp` 或 native HTTP/1.1 的默认行为。
+- TLS ALPN 只在 HTTP/2 实现通过全部验收后增加 `h2`；当前 native 只宣告 `http/1.1`，误配 `h2` 会在启动时失败。
+- Handler、Service、统一响应、requestId、可信代理和业务日志继续复用现有 `httpx.Context` 与 `http.Handler` 边界。
+- h2c 只用于本地测试，生产入口使用 TLS + ALPN；不能把明文升级路径默认为公网协议。
+
+## 连接和流的生命周期
+
+1. accept loop 先执行连接上限检查，再执行 TLS 握手；握手受独立超时约束，不能占满连接槽位后无限等待。
+2. TLS 协商得到 `h2` 后进入 HTTP/2 connection state；其他 ALPN 直接关闭，不能把 HTTP/2 preface 交给 HTTP/1.1 解析器。
+3. 每个 stream 创建独立的 `http.Request` 和取消 context。`RST_STREAM` 只取消当前请求，TCP 断开才取消该连接上的所有请求。
+4. `MaxConcurrentRequests` 是所有连接共享的全局请求闸门；`MaxConcurrentStreams` 限制单连接并发流；两者都必须在收到完整请求体前生效。
+5. `MaxHeaderBytes` 沿用标准库默认 1 MiB 上限，`MaxBodyBytes` 默认限制请求体为 8 MiB；已声明超限的请求在进入业务 handler 前返回 413，未声明长度的 body 通过受限 reader 读取，避免业务层无意间把整个请求体加载到内存。
+6. 服务关闭时停止 accept，发送 GOAWAY 拒绝新流，等待活动流排空；超过 `ShutdownTimeout` 后关闭连接并取消剩余请求。实验 Runner 已覆盖这条顺序。
+
+## 必须可观测的状态
+
+HTTP/2 版本需要在 native `Stats` 之外至少记录：活动 stream、被拒绝 stream、连接级 protocol error、RST_STREAM、GOAWAY 发送次数，以及因流控或并发闸门触发的拒绝。实验 Runner 当前已通过 `ActiveRequests`、`RejectedRequests`、`ProtocolErrors`、`RSTStreams`、`GoAwaySent` 和 `GoAwayFrames` 暴露活动/拒绝/协议错误/客户端重置/优雅关闭快照；帧观察器只解析 9 字节头部并跳过 payload，不会缓存大 body。计数必须是原子快照，不能在 metrics handler 中锁住连接状态机。
+
+## 进入实现前的验收矩阵
+
+- TLS ALPN：只协商 `h2`，HTTP/1.1 客户端仍由现有 native 路径处理；不支持的 ALPN 在握手前后都不会误入错误解析器。
+- 多路复用：一个连接并发至少 128 个 stream，响应和 requestId 不串线，在流与连接级发送额度充足时，单个慢 stream 不阻塞其他可发送 stream（实验 Runner 已覆盖 128 路同连接 stream）。
+- 流控：慢读取、慢写、窗口耗尽和大 body 都能恢复；内存不会随未消费 body 无限增长。实验 Runner 已覆盖 2 MiB 慢读取 body 和请求体上限，以及客户端将 stream 窗口设为零时的大响应阻塞、同连接 204、其他连接带 body 响应、WINDOW_UPDATE 恢复发送和 RST_STREAM 取消回收；连接级独立测试将初始 stream 窗口设为 128 KiB，仅消耗默认 65,535 字节连接窗口，确认暂停与隔离，连接级 WINDOW_UPDATE 后恢复并复用连接；持续慢客户端混合长测也已通过。连接级窗口耗尽时，同连接的其他 DATA 也受该窗口约束，HEADERS 和其他 TCP 连接仍可继续。
+- 取消：RST_STREAM、客户端断开、服务关闭分别只影响应受影响的请求，并能在 metrics 中看到回收；当前实验 Runner 已覆盖 RST_STREAM 与服务关闭，包括客户端零接收窗口造成写阻塞时，关闭超时强制解除写阻塞、取消请求并回收连接。
+- 背压：连接上限、全局 stream 上限、单连接 stream 上限和 header/body 上限均能快速拒绝并自动恢复。实验 Runner 已增加 TLS 未完成握手占满连接槽位时的及时拒绝、握手超时回收及后续正常 HTTPS 请求恢复验收。
+- 代理联调：Nginx 的 TLS/h2 回源、Keep-Alive、超时/取消及 GOAWAY 排空已由 `verifyHTTP2Proxy.py` 验证。旧实例处理中的 POST 能正常完成，新请求转入备用实例，旧实例连接与请求归零。此测试使用单进程 Nginx，未验证 Nginx master/worker 重载或 Cloudflare 实网部署。`verifyProxy.py` 继续承担 native HTTP/1.1 TLS 回源验收。
+- 长测：Linux amd64 至少 30 分钟 TLS、多连接、多 stream、慢客户端混合场景；要求 0 协议错误、0 请求串线，连接、stream、goroutine 和 FD 在停止后回收。单连接场景与 8 连接慢上传/慢下载混合场景均已通过，原始日志与采样分别保存在两个报告中。
+
+统一启动配置已接入 `omni.New`：`GO_OMNI_TRANSPORT=http2` 加证书和私钥可显式选择实验适配器，业务路由不需要改变；native 仍只协商 HTTP/1.1。参考业务增加了三种适配器的真实网络验证与排空/超时回归。下一步是业务环境试用、native 的 HTTP/1.1 与 HTTP/2 多协议监听器设计和接入回归，不能仅通过添加 `h2` 到 native 的 TLS ALPN 就宣告接入完成。需要成熟 HTTP/2 入口时可使用 `transport/nethttp` 或代理终止后回源 HTTP/1.1。
