 # Changelog
 
+## Unreleased
+
+- 新增 `TestNginxHTTP2Proxy` 与 `scripts/verifyHTTP2Proxy.py`：验证两段 TLS/h2、回源连接复用、证书校验拒绝、超时/客户端取消恢复，以及 GOAWAY 下的新旧实例切换和请求排空。Linux amd64、Nginx 1.30.5 普通与 race 模式各 3 轮通过；保留源码/镜像/日志校验信息和实际执行记录。
+- HTTP/2 代理验收的编译与测试阶段顺序运行，均限制 2 核、2 GiB、256 个进程/线程；集成测试禁用外部网络并使用只读根文件系统。总时限、SIGTERM、SIGHUP 清理实测通过；native 默认协议保持 HTTP/1.1。
+- 新增 `TestTLSMixedSoak` 与 `verifyHTTP2.py --scenario mixed`：8 条 TLS 连接、128 个 worker 持续混跑普通请求、慢上传和慢下载，校验 TLS/HTTP2、requestId、响应内容及传输摘要；分别统计三类请求与每条连接覆盖情况，并记录退出/GC 后的回收数据。
+- 完成 Linux amd64 30 分钟多连接慢客户端混合长测：53,191,687 次请求（含 106,971 次慢上传、5,588 次慢下载），0 失败与协议错误；采样 RSS 峰值约 116.6 MiB，连接/请求、goroutine 和 FD 回收，释放测试数据后存活堆约 450 KiB。保留完整日志、120 份采样及每条连接的分类计数。
+- 新增独立 `transport/http2` 实验 Runner：支持 h2c/TLS h2、连接上限、全局请求并发闸门、GOAWAY 排空、RST_STREAM 单流取消和生命周期统计；不改变 native HTTP/1.1 默认路径。
+- HTTP/2 实验 Runner 增加标准 1 MiB 头部上限、默认 8 MiB 请求体上限、128 路同连接多路复用、2 MiB 慢读取流控验收、协议错误、RST_STREAM 和 GOAWAY 帧计数；已声明超限请求在进入业务 handler 前返回 413。
+- 新增可配置时长的 HTTP/2 TLS soak：默认 3 秒，Linux 验收可通过 `GO_OMNI_HTTP2_SOAK_DURATION=30m` 覆盖，混合验证 128 路 stream、慢 handler、请求体、Keep-Alive 和退出回收。
+- HTTP/2 soak 每 15 秒输出请求/失败数、Go 堆、Linux RSS、goroutine、FD 和协议统计；校验响应协议、内容和独立请求 ID，不再忽略压测期限附近已发出请求的失败。
+- 补充 HTTP/2 慢响应流窗口为零时的隔离与恢复验收：同连接 204、另一连接带 body 响应、WINDOW_UPDATE 恢复发送及 RST_STREAM 释放请求槽位；补充 TLS 握手未完成时的连接上限拒绝、握手超时回收和正常请求恢复。
+- 补充连接级接收窗口耗尽测试：保持 stream 信用充足，消费完 65,535 字节连接窗口后确认大响应暂停，同连接 204 和另一条连接仍可完成，连接级 WINDOW_UPDATE 恢复后继续复用；补充零窗口阻塞写在关闭超时后解除阻塞、取消请求与连接回收的验收。
+- 新增 `scripts/verifyHTTP2.py`，固定在 Go 1.25 Linux 容器中运行 HTTP/2 TLS 长测；默认使用普通模式，`--race` 默认运行 60 秒。容器默认限制为 2 核、2 GiB 内存、256 个进程/线程，带总时限、中断清理和日志大小限制。
+- 完成 Linux amd64 单 TLS 连接、128 个 worker 的 30 分钟 HTTP/2 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（包含客户端和服务端），退出后连接/请求/FD 回收；保留原始日志和 120 份采样。
+- native TLS 明确限制 ALPN 为 `http/1.1`：缺省自动宣告该协议，误配置 `h2` 等未实现协议时在启动阶段报错。
+- native `Server.Stats()` 新增连接和请求过载拒绝计数；新增可信代理配置，访问日志只在 socket 对端属于配置网段时解析 `X-Forwarded-For`。
+- 新增 transport-neutral `metrics` 包，支持请求数、错误数、in-flight、累计耗时和状态分布，并可直接注册 `/metrics` 接口。
+- native 新增 `Server.Stats()`，提供 accepted connections、active connections 和 active requests 生命周期指标。
+- native 请求体改为流式读取，Content-Length 与 chunked body 不再在进入 Handler 前整体复制到内存；保留大小限制、读超时、trailer 校验和 Keep-Alive 排空。
+- 统一标准库与 native 的真实 TCP benchmark，增加固定并发档位、响应状态与读写错误检查。
+- 新增独立进程并发与长连接内存测量工具，记录成功吞吐、P95/P99、服务端分配、空闲连接堆内存和回收情况；修正并行 `ns/op` 与客户端/服务端混合分配的解释。
+- 加固 native HTTP/1.1 解析边界：校验 Host、重复 Content-Length、Connection token、Transfer-Encoding、控制字符和响应头名称；补充 HTTP/1.0 Keep-Alive、HEAD、204 以及异常请求测试。
+- native 支持带 trailers 的 chunked 请求体，并继续通过 `MaxBodyBytes`、读超时和头部上限控制解析内存与连接占用。
+- native 响应实现 `http.Flusher`：HTTP/1.1 流式响应自动使用 chunked framing，普通响应继续自动生成 `Content-Length`。
+- native 在长 Handler 运行期间监测客户端断开并取消请求 context，流式写失败同步取消；短请求延迟启动监测，管线数据保留给下一次请求。补充断开、监测退出和长连接复用验收。
+- native 增加 `ServeTLS` / `RunTLS` 和 `TLSConfig` 启动入口，App.RunWith 可以直接启用 TLS；补充真实 TLS 客户端握手、请求和优雅退出验收。
+- native 请求补齐 `Request.TLS` 连接状态；Linux/arm64 容器通过全量 race、vet、build，以及 TLS 并发、Keep-Alive、慢握手和连接上限回收验收。
+- 补充慢请求体超时、大请求体和同连接管线请求验收，确认流式 body 读取超时会取消请求并关闭连接，连续请求不会串线。
+- 补充 `MaxConnections` 满载拒绝与槽位释放验收，确认请求完成后连接容量可再次使用。
+- 补充 `MaxConcurrentRequests` 过载恢复验收，确认 503 拒绝后请求槽位释放并可继续处理新请求。
+- 增加高频建连/断连的状态池 churn 验收，覆盖连接对象回收与容量复用。
+- 新增 Linux Nginx 反向代理验收脚本，覆盖 native TLS、Keep-Alive、上游超时和优雅关闭。
+
+## v0.6.0-preview
+
+- native 网络层完成流式 Content-Length / chunked body、慢请求头、慢 body、慢 TLS 握手和 TLS 请求元数据验收；Handler 可在 body 未完全到达时开始读取，超时、畸形和超限 body 会被拒绝并关闭连接。
+- 将 native 连接 churn race 验收扩展为 16 个 worker、3,200 次建连/断连，并覆盖明文与 TLS 的连接上限、Keep-Alive 和槽位回收。
+- perfcheck 支持最长 30 分钟持续场景，新增 Linux 文件描述符采样；固定记录服务端堆、goroutine、连接数、accept 数和 FD 回收状态。
+- 新增 `scripts/verifyLinux.py`，在 `golang:1.25` Linux 容器内统一执行 race、vet、build 和可选 TLS / 非 TLS 压测。
+- 完成 Linux/arm64 30 秒高并发回归：128 并发流量、512 条空闲连接，TLS 与非 TLS 均为 0 错误，连接、goroutine 和 FD 回收正常；原始报告见 `performance/linuxSoak.json` 和 `performance/linuxSoakTLS.json`。
+
+## v0.5.0
+
+- 新增 `transport/native` 第一版自研 HTTP/1.1 服务端，接管 TCP 监听、连接、Keep-Alive、请求解析、响应写回和优雅关闭。
+- 新增 `App.RunWith` / `omni.Runner` 启动边界；native 通过标准 `http.Handler` 接入，现有 Handler、Service 和 Repository 无需修改。
+- native 支持 `Content-Length` / chunked 请求体、请求头 / 请求体限制、读写超时和服务关闭时的请求取消；通过对象池和 `MaxConnections` / `MaxConcurrentRequests` 控制高并发内存。
+- `omni.New()` 默认仍使用只依赖标准库的 `transport/nethttp` 路由，native 作为显式启用的网络层预览实现。
+
+## v0.4.0
+
+- **破坏性变更**：移除 Gin 适配器及其全部依赖，`omni.New()` 默认使用只依赖标准库的 `transport/nethttp`。
+- 移除 Gin 专属的 `Config.Mode` / `WithMode` API；网络层运行模式由具体适配器或启动层自行配置。
+- 公共 `httpx.Router`、`transport/transporttest.Run` 和 `omni.NewWithRouter` 保留，自研网络层无需修改业务 Handler / Service 即可接入。
+- benchmark 改为标准库路由和完整 GoOmni 请求链，新增 `scripts/verifyPerformance.py` 作为 race、vet、build 和性能基线入口。
+- 远程业务试用、脚手架、适配器契约和 MySQL 验收全部迁移到 `v0.4.0`。
+
+## v0.3.1
+
+- 新增独立业务模块验收 `scripts/verifyBusiness.py`：从远程 `v0.2.0` 升级到 `v0.3.1`，验证无本地 replace、配置加载、结构化日志、requestId、CRUD、校验错误、业务错误和优雅退出。
+- 脚手架与各项远程验收脚本默认跟随 `v0.3.1`，新项目会固定到最新补丁版本。
+
+## v0.3.0
+
+- 新增公共适配器验收套件 `transport/transporttest.Run` 和远程消费验收脚本 `scripts/verifyTransports.py`。Gin、nethttp 使用同一套路由与业务处理链测试，并通过完整用户 CRUD 与 race 验证。
+- 统一参数、分组、方法、URL 解码、路由优先级及 404/405 规则；Gin 405 的 Allow 由适配层计算，避免方法树回退状态带入无关方法。
+- 统一路由注册校验；非法路径、重复路由、参数名冲突和 catch-all 冲突在注册时 panic。
+- `App.Handle` / `RouterGroup.Handle` 支持在完整业务中间件链内显式注册 HEAD、OPTIONS 与扩展方法。
+- JSON 在提交响应前编码，编码失败可正确返回统一 500；通过 Context 已提交的响应不会因后续错误、panic 或重复响应追加内容，访问日志保留实际提交的状态。
+- 验证 requestId 与业务日志关联、认证授权短路、请求并发隔离、context 值与 deadline 保留，以及真实客户端取消传入 Service。
+- **升级行为调整**：Gin 不再自动重定向尾部斜杠；nethttp 不再忽略尾部斜杠，通配参数包含开头的 `/`，Any 收敛为九种标准方法。HEAD 不自动回退 GET，其他方法需显式注册。404/405 为统一纯文本响应，405 附排序后的 Allow。
+- `gin.NewWithEngine` 应用 GoOmni 路由策略；原生 Gin 扩展与 Raw 流式响应不属于可移植契约。详见 `transport/README.md`。
+- 新增业务试用验收 `scripts/verifyBusiness.py`：独立目录内固定远程版本，执行 `v0.2.0` → `v0.3.0` 升级，验证生成业务服务的配置、日志、requestId、CRUD、参数校验、错误映射和优雅退出。
+
+## v0.2.0
+
+- 新增 `go-omni new --database mysql`，生成数据库配置、MySQL Repository、ServiceContext、`schema.sql` 和数据库就绪探针；默认仍使用内存存储。
+- 两种存储模式的脚手架均提供完整 CRUD、分页、输入校验与统一响应。新生成项目的 `POST /users` 从直接返回用户对象改为标准响应封装，用户对象位于 `data`。
+- MySQL 启动时检查连接和表结构，失败时清理连接池；数据库停机后 readiness 返回 503，恢复后自动重新检查。
+- MySQL Repository 支持 `*sql.DB` 和 `*sql.Tx`，可在同一事务中复用业务查询。
+- 修复 `MaxIdleConns=0` 未生效的问题，数据库健康检查增加超时限制。
+- 新增隔离 MySQL 容器验收脚本，覆盖真实 CRUD、事务提交和错误/panic/取消回滚、持久化、资源清理及数据库停机恢复。
+
 ## v0.1.1
 
 - 修复脚手架生成项目固定依赖不存在的 `v0.0.0`；远程安装的 CLI 默认使用自身版本，支持 `--framework-version` 指定完整版本号。

+# GoOmni 性能基线
+
+这轮测量显示 native 与标准库处于相同吞吐量级，在本机短时测试中，native 的空闲长连接堆内存更少。当前 native 仅实现 HTTP 的部分能力，尚不能据此判断生产容量或替代完整标准库服务端。
+
+## 运行方式
+
+```sh
+# race、vet、build，以及进程内和真实 TCP benchmark
+python3 scripts/verifyPerformance.py
+
+# 另加独立服务进程的并发、延迟和空闲长连接内存矩阵
+python3 scripts/verifyPerformance.py --load --output /tmp/goOmniPerf.json
+
+# 只运行独立进程矩阵，默认每档 2 秒、3 轮
+go run ./internal/perfcheck --duration 2s --count 3 --output /tmp/goOmniPerf.json
+
+# 在 Linux Docker 容器内固定运行 race、vet、build 和 TLS 压测
+python3 scripts/verifyLinux.py --load --tls --duration 30s \
+  --concurrency 128 --idle 512 --count 1 \
+  --output performance/linuxSoakTLS.json
+
+# 发布候选验收可把持续流量延长到 30 分钟
+python3 scripts/verifyLinux.py --load --tls --duration 30m \
+  --concurrency 128 --idle 512 --count 1 \
+  --output performance/linuxSoakTLS-30m.json
+
+# Linux 上用 Nginx 反向代理接入 native TLS 服务，检查 Keep-Alive、超时和优雅关闭
+python3 scripts/verifyProxy.py
+```
+
+可通过 `--concurrency 1,32,128` / `--idle 128,1024` 调整矩阵；传空字符串可跳过对应场景。工具只监听本机随机端口，每个场景启动独立服务进程，并在结束后关闭客户端、检查连接排空、关闭服务。响应状态、完整响应体、requestId 或传输错误均计入失败，不能把快速返回的错误页算成成功吞吐。
+
+Linux 验收脚本使用 `golang:1.25` 容器，固定执行 `go test -race ./...`、`go vet ./...`、`go build ./...`，再按参数运行 perfcheck。perfcheck 在 Linux 读取 `/proc/self/fd`，报告连接建立期间的文件描述符峰值以及回收后的数量；同时记录服务端堆、goroutine、连接数和累计 accept 数。30 秒报告用于快速回归，30 分钟命令用于发布前持续压测。
+
+## 2026-09-21 本机测量
+
+环境：Go 1.25.0、darwin/arm64、Apple M2 Max、GOMAXPROCS=12。网络实现来自 `3d5f225` 工作树（native 与 v0.6.0-preview 相同）；本次新增测量工具，不修改服务端实现。原始测量值见 [tcpBaseline.json](performance/tcpBaseline.json)。报告时间为 UTC，北京时间是 9 月 21 日。
+
+每个并发档位持续约 2 秒、重复 3 轮，每轮交替标准库/native 的先后顺序。下表为各指标的三轮中位数；全部流量场景共完成 **2,660,828** 次请求，错误 **0**。另有 128 / 1,024 条空闲长连接的建立、保持和回收测试。
+
+| 并发请求 | 标准库成功请求/秒 | native 成功请求/秒 | 标准库 P95 | native P95 | 标准库 P99 | native P99 |
+| --- | ---: | ---: | ---: | ---: | ---: | ---: |
+| 1 | 19,731 | 21,497 | 0.074 ms | 0.070 ms | 0.139 ms | 0.119 ms |
+| 32 | 90,099 | 88,812 | 1.016 ms | 0.983 ms | 1.507 ms | 1.507 ms |
+| 128 | 112,422 | 112,105 | 3.277 ms | 3.408 ms | 4.719 ms | 4.981 ms |
+
+128 并发时，两者吞吐差约 0.3%，native 的尾延迟略高。基于这组结果，暂时没有理由仅为健康接口吞吐就改成手写事件循环。
+
+| 空闲 Keep-Alive 连接 | 标准库新增堆内存 | native 新增堆内存 | 标准库约每连接 | native 约每连接 |
+| --- | ---: | ---: | ---: | ---: |
+| 128 | 1.275 MiB | 0.658 MiB | 10,444 B | 5,389 B |
+| 1,024 | 9.871 MiB | 5.137 MiB | 10,108 B | 5,260 B |
+
+1,024 条空闲连接时，native 的新增堆内存约少 48%。这是**服务端 Go 堆内存增量**，不包括 goroutine 栈、进程其他内存和内核 socket 缓冲区，不能解释为整个进程内存减半。同档服务端 `StackInuse` 分别约为标准库 8.75 MiB、native 8.69 MiB，原始报告单独记录。
+
+连接断开后，两者连接数都回到 0，goroutine 分别回到 2 / 3 的初始基线。一次 GC 后仍有对象池缓存；第二次 GC 后，总堆内存中位数回到约 2.10 / 2.08 MiB（启动基线约 1.54 MiB）。堆内存不会立刻精确回到启动数值，不把缓存保留解释为泄漏，也不把这轮短测解释为长期无泄漏证明。
+
+128 并发时，**服务端单独累计分配**约为标准库 4,454 B/请求、47 次/请求，native 4,297 B/请求、55 次/请求。native 的分配字节较少、次数较多；具体来源需用分配 profile 确认，不能仅凭总量归因于 HTTP 桥接或 JSON。
+
+## 统计边界
+
+- 同一台机器上，压测客户端和服务端是两个独立进程。两者使用同一健康接口、相同小型 JSON 响应、固定 `requestId=perfCheck` 和 Keep-Alive；不启用访问日志、TLS 或数据库。
+- 并发模型为闭环：每个 worker 等上一个请求完成后发下一个。实际经过时间包含最后请求排空；吞吐只计算成功响应。不能据此推断开放到达流量下的排队或过载表现。
+- 延迟从客户端发起请求到完整响应校验完成，包含失败请求。直方图使用每个 2 的幂区间内 16 档，报告桶上界，舍入误差至多约 6.25%。小幅差别不应过度解释。
+- 服务端 `runtime.MemStats` 通过独立 stdin/stdout 控制通道读取，客户端内存不计入。累计分配差值包含少量采样开销。堆峰值每 200 ms 采样，可能错过瞬时峰值；这些指标不是进程 RSS。
+- Linux 文件描述符来自服务端子进程的 `/proc/self/fd`，包含标准输入输出、监听 socket 和连接；macOS 等没有该路径的平台会省略该字段。回收后的数量应回到启动附近，不能代替内核 socket 缓冲或 RSS 测量。
+- 空闲场景在所有连接完成健康请求后做 GC 再采样。新增堆内存包括连接、缓冲区及分摊的运行时开销。`after` 为客户端断开并排空后一次 GC，`afterReclaim` 为第二次 GC，用于观察对象池缓存释放。
+- native 配置上限为 8,192 连接 / 4,096 活跃请求；本轮并发低于上限，未验证过载保护容量。标准库没有同样的并发闸门；比较包括各自真实实现的开销。
+- 可用 `python3 scripts/verifyPerformance.py --load --tls --duration 2s` 运行 TLS 版本的独立进程矩阵。该模式在每个子进程生成短期自签名证书，客户端仅用于本机基准验证；本报告的历史表格仍是无 TLS 数据。

+## benchmark 口径修正
+
+## TLS 验收记录
+
+macOS arm64 本机的 5 秒 TLS 矩阵见 [tlsBaseline.json](performance/tlsBaseline.json)：1 / 32 / 128 并发和 128 / 1,024 条空闲连接均为 0 错误；native 在 128 并发约 114,232 req/s，1,024 条空闲 TLS 连接的服务端堆增量约 8.94 MiB，连接关闭后 goroutine 回到基线。
+
+Linux arm64 容器使用 Go 1.25.14、GOMAXPROCS=4 运行 3 秒矩阵，见 [tlsBaselineLinux.json](performance/tlsBaselineLinux.json)：1 / 32 / 128 并发和 128 / 512 条空闲连接均为 0 错误；native 在 128 并发约 99,876 req/s，512 条空闲 TLS 连接的服务端堆增量约 4.47 MiB，连接关闭后 goroutine 回到基线。容器验证同时通过全量 race、vet、build。
+
+Linux arm64 的 30 秒高并发回归见 [linuxSoak.json](performance/linuxSoak.json) 和 [linuxSoakTLS.json](performance/linuxSoakTLS.json)：两份报告均使用 128 并发流量和 512 条空闲连接，所有场景错误为 0；native 非 TLS 约 146,614 req/s、TLS 约 149,720 req/s，空闲连接堆增量分别约 2.57 MiB 和 4.47 MiB，FD 均由 7 增至 519 并回到 7，goroutine 均回到启动附近。
+
+目标 Linux amd64 服务器的 30 分钟 TLS 验收使用 1 个 CPU、1 GiB 内存的隔离 Docker 容器完成：net/http 约 11,865 req/s，native 约 13,098 req/s，两个流量场景均为 0 错误；native 的 P95/P99 为 44.040/52.429 ms。512 条空闲 TLS 连接时，native 服务端堆增量约 4.50 MiB（约 9,215 B/连接），文件描述符由 7 增至 519 后回到 7，goroutine 和连接均正常回收。原始报告保存在服务器的 `performance/linuxServerSoakTLS.json`。
+
+`BenchmarkTransportTCPApplicationRequest/{nethttp,native}/concurrency{1,32,128}` 使用同一测试入口、客户端、应用与响应检查。原先独立的 `BenchmarkNativeApplicationRequest` 已合并，避免两个入口配置漂移。`verifyPerformance.py` 会一并运行。
+
+并行 benchmark 的 **`ns/op` 是总经过时间除以请求数，反映吞吐成本，不是单请求延迟**。`B/op` / `allocs/op` 统计同一进程中的客户端与服务端总分配。此前报告的 native 15.4–16.7 µs/op、约 7.8 KB/op、100 allocs/op 应按这个含义理解，不能作为服务端延迟或独立内存指标。
+
+`BenchmarkTransportRouteDispatch` 和 `BenchmarkTransportApplicationRequest` 继续保留，分别测进程内路由分发和完整框架处理链；不包含 TCP，不能直接与上述网络延迟比较。
+
+后续通过 30 分钟命令完成发布前持续压测，并在目标反向代理和部署环境继续观察内核 socket 缓冲、FD 上限与真实业务流量；再通过 profile 决定是否优化对象分配或事件状态机。

+- 新增 `transport/native` 第一版自研 HTTP/1.1 服务端：自行管理 TCP listener、Keep-Alive、Content-Length / chunked 请求解析、响应写回、读写超时和优雅关闭；通过 `App.RunWith` 接入，业务 Handler / Service 保持不变。
+- 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。

+- 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。
+- 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。

 # Transport adapters
 
-GoOmni 的业务处理链依赖 `httpx.Router`，不直接依赖具体网络框架。当前的 `transport/gin` 只负责把 Gin 的路由、路径参数和响应写入转换成标准 HTTP 接口；`transport/nethttp` 提供了一个只使用标准库的参考实现。
-
-使用标准库适配器：
+业务 Handler 依赖 GoOmni 的 `httpx.Context`，Service 接收标准 `context.Context`。适配器只在启动入口组装：
 
 ```go
 import (
-	omni "git.yuntuo.hk/k2safe/go-omni"
-	netrouter "git.yuntuo.hk/k2safe/go-omni/transport/nethttp"
+    omni "git.yuntuo.hk/k2safe/go-omni"
+    netrouter "git.yuntuo.hk/k2safe/go-omni/transport/nethttp"
 )
 
 application := omni.NewWithRouter(netrouter.New())
+registerRoutes(application) // 与 omni.New() 复用同一份业务注册代码
 ```
 
-后续自研网络层时，实现以下能力即可接入现有 `app`、中间件和业务 Handler：
+`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。
 
-- `httpx.Router`：注册路由、分组并实现 `http.Handler`。
-- `httpx.RouterGroup`：注册分组内路由。
-- 适配器为请求 context 注入 `httpx.WithRouteParams` 和 `httpx.WithRoutePattern`。
+`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。
 
-业务层不应该导入具体 transport 包；它们只是网络层实现。
+`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，拒绝数可从 `Stats()` 采集。
+
+访问日志默认只记录 TCP socket 对端地址。部署在 Nginx、Cloudflare 等反向代理后面时，通过 `omni.WithTrustedProxies("127.0.0.1/32")` 或 `GO_OMNI_TRUSTED_PROXIES` 配置可信代理网段，框架才会从 `X-Forwarded-For` 右向左校验并取得真实客户端地址；未配置时转发头不会被信任。
+
+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。
+
+使用自研服务端：
+
+```go
+application := omni.New()
+server := native.New(nil)
+if err := application.RunWith(ctx, server, ":8080"); err != nil {
+    log.Fatal(err)
+}
+```
+
+`omni.New()` 默认仍使用 `transport/nethttp` 路由；native 服务端是显式启用的预览实现，等协议和连接边界稳定后再考虑切换默认启动器。
+
+TLS 可以直接作为 `App.RunWith` 的启动配置：
+
+```go
+server := native.New(nil)
+server.TLSConfig = &tls.Config{Certificates: certificates}
+if err := application.RunWith(ctx, server, ":8443"); err != nil {
+    log.Fatal(err)
+}
+```
+
+需要自己持有 listener 或配置证书文件时，分别使用 `ServeTLS` 或 `RunTLS`；TLS 握手仍受 native 的读超时、连接上限和优雅关闭控制，Handler 可通过 `Request.TLS` 读取标准 `tls.ConnectionState`。
+
+native 当前只宣告 TLS ALPN `http/1.1`。未配置 `NextProtos` 时会自动补上；如果配置了 `h2` 等未实现协议，服务会在启动时直接返回错误，避免 TLS 协商成功后再被 HTTP/1.1 解析器拒绝。需要 HTTP/2 时，先让 Nginx/Cloudflare 在边缘终止 HTTP/2，再以 HTTP/1.1 回源；或继续使用默认的 `transport/nethttp` 适配器。native 的 HTTP/2 会在独立协议设计和压测完成后再进入。
+
+HTTP/2 的进入条件、连接/流生命周期、背压和长测矩阵见 [native HTTP/2 进入条件](native/HTTP2.md)。
+
+## 可移植路由规则（v0.3.0）
+
+| 项目 | 约定 |
+| --- | --- |
+| 路径 | 顶层路由必须以 `/` 开头；区分大小写。禁止重复斜杠、`.` / `..` 段、查询串和片段标识。 |
+| 参数 | `/users/:id` 匹配一个非空路径段；参数必须占据整个段，同一路由内名称唯一。 |
+| 通配 | `/files/*path` 仅允许出现在末尾，值包含开头的 `/`；`/files/` 对应 `/`，`/files` 不匹配。 |
+| 路由优先级 | 相同方法内，从左向右比较，静态段优先于参数段；更具体的分支匹配失败后允许回退。 |
+| 注册冲突 | 同方法重复注册、相同前缀处参数名冲突、catch-all 与同级分支冲突，均在注册时 panic。不同方法可用同一路径。 |
+| 分组 | 支持嵌套与相对路径。`Group("/api").Handle("GET", "", h)` 注册 `/api`，传 `"/"` 则注册 `/api/`。 |
+| 尾部斜杠 | `/users` 与 `/users/` 是不同路由；不自动重定向、补斜杠或清理请求路径。 |
+| URL 编码 | 使用已解码的 `URL.Path`；例如 `%2F` 作为路径分隔符，`+` 保留为加号。 |
+| 方法 | `Handle` 接受大写字母组成的方法名；HEAD 不自动复用 GET，OPTIONS 不自动成功。 |
+| Any | 注册 GET、POST、PUT、PATCH、HEAD、OPTIONS、DELETE、CONNECT、TRACE 九种方法；其他方法需显式注册。 |
+| 404 / 405 | 未找到路径返回纯文本 404；路径存在但方法不支持时返回纯文本 405，`Allow` 去重并按字母排序。 |
+| 并发 | 启动前完成路由注册；允许并发处理请求，各请求参数、业务值、requestId 必须隔离。 |
+
+HTTP 回退响应属于路由层，不进入应用路由中间件，不携带统一 JSON 封装或 requestId。业务 Handler 返回的错误则经过统一 JSON 错误处理。
+
+业务层通过 `application.Handle("HEAD", path, handler)` 或 `group.Handle("OPTIONS", path, handler)` 显式注册其他方法，同样经过框架中间件和错误处理。
+
+## 业务行为
+
+- 同一套 Handler、Service、中间件用于两种适配器；应用、分组、嵌套分组、路由中间件依次进入、反序退出。
+- `Use` 只影响后续注册的路由。鉴权失败短路处理链，panic 转为统一 500。
+- URI / Query / JSON 绑定、业务错误、requestId 与业务日志关联一致。
+- `JSON` / `OK` 等方法先编码再发送；编码失败返回统一 500。已通过 Context 提交响应后，后续错误、panic 或重复响应不会追加 JSON。
+- 客户端断开会取消传入 Service 的 context；适配时保留原有 context 的值、截止时间和取消信号。
+- `Raw()` 是高级逃生口；直接写入、流式响应、Hijack 等行为不属于上述 Context 响应追踪契约，勿与自动响应方法混用。
+
+## 自研适配器验收
+
+实现 `httpx.Router` / `httpx.RouterGroup`，在调用 Handler 前通过 `httpx.WithRouteParams` 和 `httpx.WithRoutePattern` 注入请求元数据。使用外部测试包接入公共验收套件：
+
+```go
+package myrouter_test
+
+import (
+    "testing"
+    "git.yuntuo.hk/k2safe/go-omni/httpx"
+    "git.yuntuo.hk/k2safe/go-omni/transport/transporttest"
+    "example.com/project/myrouter"
+)
+
+func TestContract(t *testing.T) {
+    transporttest.Run(t, func() httpx.Router { return myrouter.New() })
+}
+```
+
+工厂需每次返回新的空路由器。套件依次创建路由器，内部会发送并发请求、打开本地 HTTP 测试服务，运行时应启用 race 检查：
+
+```sh
+go test -race ./transport/... ./examples/reference
+python3 scripts/verifyTransports.py --version v0.6.0-preview
+```
+
+第一条验证标准库适配器复用完整 Handler / Service / Repository。第二条在源码目录外创建无 replace 的消费模块，从远程版本导入同一套验收包；自研适配器也应使用同一个公共测试包。
+
+当前替换边界分成两层：`transport/nethttp` 提供标准库路由，`transport/native` 进一步接管 TCP 监听、连接管理和 HTTP/1.1 协议 I/O。`App.Run` / `App.RunContext` 仍使用标准库 `net/http.Server`，需要显式调用 `App.RunWith(ctx, native.New(nil), address)` 才会启用 native 预览实现。native 当前通过标准 `http.Request` / `http.ResponseWriter` 桥接到业务层，后续可在不改 Handler / Service 的前提下逐步替换解析器和响应写回。

+# 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。
+
+这些实验结果已经覆盖到 Nginx HTTP/2 回源联调。下一步是统一启动配置、native 的 HTTP/1.1 与 HTTP/2 协议接入回归，以及业务环境试用，不能仅通过添加 `h2` 到 native 的 TLS ALPN 就宣告接入完成。当前继续保持显式选择实验适配器；默认 native 路径仍为 HTTP/1.1，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。
