+# Changelog
+
+## Unreleased
+
+- 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，确认请求体未完整读取时不会进入业务 Handler，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。
+- 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。
+
+## v0.6.0-preview
+
+- native 网络层完成慢请求头、慢 Content-Length / chunked body、慢 TLS 握手和 TLS 请求元数据验收，未完整读取的请求不会进入业务 Handler。
+- 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。
+- 显式远程版本禁用自动本地替换；本地替换路径支持空格，并按精确 module path 识别框架目录。
+- 生成项目通过 `signal.NotifyContext` 接入优雅退出，启动过程中的错误会先执行 defer 清理再报告。
+- `App.Run` 自动处理 `SIGINT` / `SIGTERM`；`RunContext` 仍由调用方控制，退出超时会关闭活跃连接。
+- 增加请求排空、超时取消、启动失败清理测试，以及远程脚手架和真实进程信号验收脚本。
+
+## v0.1.0
+
+- 首个可试用版本：应用生命周期、HTTP 抽象、Gin 与标准库路由适配器、统一响应与错误。
+- 提供配置、日志、校验、认证接口、数据库基础能力、健康探针和项目脚手架。

+# 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
+```
+
+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。
+
+`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。

+- 已验证初始化失败、缺少表结构、正常退出时关闭连接池，以及数据库停止后的 readiness 503、恢复后的 200。
+- 自动验收入口：`python3 scripts/verifyDatabase.py --version v0.2.0`；结束后清理本次测试容器、匿名卷和临时项目。
+
+## 3. 网络适配一致性（已完成，v0.4.0）
+
+- 标准库适配器运行公共契约测试，并为自研网络层保留相同的接入边界。
+- 覆盖路由参数、分组、中间件、错误响应和取消传播。
+- 验收：切换适配器后，业务 Handler 和 Service 无需修改，约定的 HTTP 行为一致。
+- 新增公共 `transport/transporttest.Run`，自研适配器可直接复用；覆盖静态 / 参数 / 通配路由、分组、405 Allow、鉴权短路、错误与 panic、响应提交、requestId、并发隔离、截止时间及真实客户端取消。
+- 标准库路由实现明确的路径、方法、尾部斜杠、通配参数、Any 和 404/405 约定；不再引入 Gin 依赖。
+- 完整用户 CRUD 已用标准库适配器验证；自研适配器可直接复用同一公共契约测试包。
+- 自动验收入口：`python3 scripts/verifyTransports.py --version v0.4.0`，从源码目录外消费远程版本与公共契约测试包。
+
+## 4. 实际业务试用（已完成，v0.4.0）
+
+- 在独立业务目录生成 billing service，先固定远程 `v0.2.0`，再升级到 `v0.4.0`，全程无本地 replace。
+- 验证环境配置、结构化访问日志、requestId 关联、参数校验、业务错误映射、CRUD、优雅退出和升级后的 race 测试。
+- 业务试用没有要求修改 Handler / Service；现有公共 API 足以支撑一套分层业务模块。
+- 自动验收入口：`python3 scripts/verifyBusiness.py --version v0.4.0`。
+
+## 5. 自研网络层、稳定性与性能基线（v0.6.0-preview 验收完成）
+
+- 已加入标准库路由和完整 GoOmni 请求链 benchmark，输出分配次数和耗时，作为未来自研网络层的对照基线。
+- 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 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。
+
+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。

 # go-omni CLI
 
-生成一个带 Handler / Service / Repository / Model 分层的服务骨架：
+从远程安装，生成一个带 Handler / Service / Repository / Model 分层的服务骨架：
 
 ```sh
-go run ./cmd/go-omni new --module example.com/billing ./billing
+go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.6.0-preview
+go-omni new --module example.com/billing ./billing
+cd billing
+go mod tidy
+go run ./cmd/server
 ```
 
+通过 `go install ...@版本` 安装的 CLI 从构建信息中读取版本，并把它固定到生成项目的
+`go.mod`。不会使用不存在的 `v0.0.0`，也不会在普通业务目录中添加本地 `replace`。
+
+需要选择其他已发布版本时，使用完整版本号：
+
+```sh
+go-omni new --framework-version v0.6.0-preview --module example.com/billing ./billing
+```
+
+`--framework-version` 禁用自动本地替换；`main`、`latest` 等浮动引用不接受为固定版本。
+源码构建的 CLI 使用代码中声明的目标发布版本；该版本未发布时请显式选择已发布版本，或用 `--framework-dir` 验证本地源码。
+
 在 GoOmni 源码目录执行时，命令会自动在生成项目的 `go.mod` 中加入本地
 `replace git.yuntuo.hk/k2safe/go-omni => ...`，便于立即运行和测试。目标目录非空时命令会停止，明确传入
 `--force` 才会覆盖脚手架文件。
+
+也可以在任意目录显式指定源码路径：
+
+```sh
+go-omni new --framework-dir /path/to/go-omni --module example.com/billing ./billing
+```
+
+默认生成内存存储版本；选择 MySQL 时：
+
+```sh
+go-omni new --database mysql --module example.com/billing ./billing
+```
+
+MySQL 项目额外包含 `schema.sql`、MySQL Repository 和可选的数据库集成测试。
+先应用建表脚本，再设置 `GO_OMNI_DB_DSN` 启动。ServiceContext 负责连接池初始化、表结构检查、
+就绪探针注册和关闭。两种模式都提供用户 CRUD、分页、输入校验和统一错误响应。
+
+生成服务默认包含 `/health/live`、`/health/ready` 和示例 `/users` CRUD。
+退出信号通过 `signal.NotifyContext` 传入 `RunContext`，Logger 的关闭函数注册到应用生命周期。
+
+发布验收使用 Python 3 标准库脚本，不需要额外 Python 依赖：
+
+```sh
+python3 scripts/verifyScaffold.py --version v0.6.0-preview
+python3 scripts/verifyDatabase.py --version v0.6.0-preview
+```
+
+脚本在源码目录外安装远程 CLI、生成项目，确认固定版本且没有 `replace`，再下载依赖、
+编译、请求接口，并对真实二进制分别发送 `SIGINT` 和 `SIGTERM`。同时验证框架 `Run` 的
+信号处理和清理回调。每个进程都必须退出码为 0、释放监听端口；临时项目和测试进程会被清理。
+
+发布前验证当前源码：
+
+```sh
+go build -o /tmp/go-omni ./cmd/go-omni
+python3 scripts/verifyScaffold.py --cli /tmp/go-omni --framework-dir .
+python3 scripts/verifyDatabase.py --cli /tmp/go-omni --framework-dir .
+```
+
+数据库验收需要本地 Docker，使用独立 MySQL 8.4 容器；不会连接已有业务数据库，结束后清理测试容器与数据卷。

 `GO_OMNI_HTTP_ADDR` 可以修改监听地址。生成项目默认提供 `/health/live` 和
 `/health/ready`，日志、请求 ID 和优雅退出等基础能力由 GoOmni 统一初始化；业务依赖集中放在项目自己的 `internal/servicecontext`。
 
-The generated layout keeps HTTP handlers, business services, repositories,
-models and a project-owned ServiceContext separate. Replace the memory
-repository with a database implementation when the service is ready for
-persistence, then add it to `internal/servicecontext`.
+服务使用 `signal.NotifyContext` 处理 `SIGINT` / `SIGTERM`。部署时构建并运行服务二进制，
+使信号直接到达服务进程：

+```sh
+go build -o server ./cmd/server
+./server

+`GO_OMNI_SHUTDOWN_TIMEOUT` 控制等待请求完成的时间，默认 `10s`。
+{{if eq .Database "mysql"}}
+`/health/ready` 已注册数据库探针：连接失败返回 `503`，数据库恢复后重新返回 `200`。
+`/health/live` 始终只检查服务存活。`GO_OMNI_DB_PING_TIMEOUT` 限制初始化检查和数据库探针的等待时间。

+
+`MAX_IDLE_CONNS=0` 禁用空闲连接，`MAX_OPEN_CONNS=0` 表示不限制连接数。
+项目会启用 MySQL `parseTime` 并按 UTC 读取 DATETIME 字段，JSON 字段保持 lowerCamelCase。
+
+事务内复用 Repository（在业务代码中导入 `database/sql` 和项目的 `internal/repository`）：
+
+```go
+err := services.DB.InTx(ctx, nil, func(tx *sql.Tx) error {
+	users := repository.NewMySQLUsers(tx)
+	_, err := users.Create(ctx, input)
+	return err
+})
+```
+
+业务函数返回错误、发生 panic 或 context 取消时会回滚。事务内必须使用基于 `tx` 创建的 Repository。
+
+可选集成测试（只针对已应用 schema.sql 的独立测试数据库）：
+
+```sh
+GO_OMNI_TEST_MYSQL_DSN='app:password@tcp(127.0.0.1:3306)/test?parseTime=true' go test -race ./...
+```
+
+未设置 `GO_OMNI_TEST_MYSQL_DSN` 时跳过数据库集成测试。框架仓库中的 `scripts/verifyDatabase.py`
+可以自动创建、验收和清理独立的 MySQL 容器。
+{{else}}
+内存模式没有外部依赖探针；后续添加依赖时，在 `internal/servicecontext` 注册检查与资源清理。

 # 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 (
@@ -11,12 +9,103 @@ import (
 )
 
 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/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。
 
-业务层不应该导入具体 transport 包；它们只是网络层实现。
+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。
+
+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`。
+
+## 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。
