 # Changelog

+## v0.27.0-preview（2026-09-29）
+
+- HTTP 配置新增 defaultMaxBodyBytes、maxBodyBytes、shutdownCancelTimeout；三种内置服务统一默认/路由/硬请求体限额，配置冲突在监听前报告完整路由与限额。native/HTTP2 不再以隐含 8 MiB 阻挡已放宽的 App 上传路由。
+- App 在所有服务入口跟踪完整请求处理链；关闭连接后有界等待处理器实际退出。超时仍有请求则返回 ErrResourcesRetained，跳过 App 清理；Runtime.Finish 继续停止后台工作但保留依赖，生成入口保留日志。
+- native 提前拒绝上传后有界半关闭连接，减少 TCP reset 吞掉错误响应；业务 HTTP 200 策略不再触发对被拒绝请求体的继续读取。
+- HTTP/2 Shutdown 同时等待连接和独立处理器，修复客户端断开后误判完成。增加真实 TLS/流式上传、取消收尾、拒绝晚到请求、资源保留和生成消费者回归，以及 httpSafety 示例。
+- 迁移：nethttp 手写普通路由新增默认 8 MiB 请求体上限，大请求显式覆盖；生成契约默认 1 MiB 保持。HTTP 停机多一个默认 5s 取消收尾窗口；外部宿主须将运行错误传给 Runtime.Finish，并遵守资源保留信号。
+
+## v0.26.0-preview（2026-09-29）
+
+- 新增独立 i18n：不可变命名空间词典、源/默认/启用语言、BCP 47 匹配、显式回退、参数/条件/基数复数和有界资源加载；不依赖 HTTP、业务或数据库。
+- Go/浏览器共用固定 CLDR 46.1 复数规则；JSON 资源版本、类型导出和按命名空间选择的语言包独立于业务错误格式。
+- 新增可选 httpi18n/errori18n 适配；错误 translation 元数据、PublicMessage 展示入口，保留原业务码/状态/失败语义/原始原因和首次幂等响应。
+- 新增 i18n check/export/types/extract；静态与动态键诊断、未知字段/重复定义/参数校验、显式覆盖；输入只读，不执行任意项目 Go。
+- 新增无前端框架依赖的浏览器模块、按需加载/切换竞态/失败保留、CLI/HTTP/表单示例及通用验收。旧项目默认行为不变。
+- 新 translation 生成代码要求 v0.26.0-preview 或具备能力的本地源码，未使用该元数据的模板最低版本保持 v0.22。
+
+- 修复 JSON 对象/数组结束定界符读取失败时丢失原始错误的问题，保留请求体限额的 HTTP 413；共享 Go 目录测试工程改用声明支持的 Go 1.22。
+

+
 从 `v0.10.0-preview` 起，业务可以只返回逻辑错误标识，框架从项目目录取得 HTTP 状态、对外业务码与公开提示。目录不依赖具体业务、数据库、身份模型或网络层，也不定义固定返回体。

+# HTTP 限额与停机
+
+从仓库根目录运行 `go run ./examples/httpSafety`，可用 `-addr 127.0.0.1:18080` 指定端口。仅使用本机 HTTP 和模拟收尾，不连接数据库或其他服务。
+
+上传验证：
+
+```sh
+dd if=/dev/zero bs=1048576 count=9 2>/dev/null | curl --data-binary @- http://127.0.0.1:8080/upload
+```
+
+普通路由默认 1 MiB，上传路由允许 16 MiB，服务硬上限 20 MiB；以上请求返回已读取的 9437184 字节。将上传路由改为 21 MiB 后，启动会报告该路由与服务硬上限冲突。实际文件上传须额外预留 multipart 字段/边界开销，并配置文件大小限制。
+
+停机验证：另一个终端执行 `curl http://127.0.0.1:8080/work`，随后在服务终端按 Ctrl-C。先等待 1s 排空，再取消请求，处理器模拟 100ms 收尾；日志中先出现 `request cleanup completed`，再出现资源关闭记录。因为用尽排空预算，本次退出仍返回超时错误。
+
+若处理器不在取消收尾窗口内退出，App 和 `deps.Finish(runErr)` 返回 `lifecycle.ErrResourcesRetained` 并跳过资源关闭。真实项目拥有的日志也必须在该错误下保留，生成入口已处理。进程应非零退出；库不自行退出进程，也不强杀 goroutine。

+
+访问 `http://127.0.0.1:8098/`，输入草稿并切换语言。只更新标题、标签和按钮文字；输入内容、提交次数和表单节点保留。浏览器模拟 `/locales/zh-Hans.json` 加载失败时保留当前语言；快速连续切换不会被旧加载覆盖。
+
+```sh
+curl -i -H 'Accept-Language: zh-CN' http://127.0.0.1:8098/api/limit
+```
+
+返回 HTTP 409，业务码 400001，中文公开提示；改成 `en` 时只改变展示文案。静态页面和语言包使用直接输出，不受公共响应格式包装。
+
+项目管理普通 UI 词典；错误源文案只在 Go Catalog 中维护，`errori18n.Source` 在装配时提供源词典，JSON 只维护中文译文。所有语言包显式嵌入，不受进程工作目录或环境变量影响。
+
+```sh
+go run ./examples/i18n -export-locale zh-Hans
+go run ./examples/i18n -catalog > /tmp/omni-i18n-errors.json
+go run ./cmd/go-omni i18n extract --catalog /tmp/omni-i18n-errors.json \
+  --locale en --namespace errors
+go test ./examples/i18n
+```
+
+前端 Pack 只导出 `ui` 命名空间，不把错误业务码、HTTP 状态、内部 cause 或未选择的文案混进去。更多检查与类型导出命令见 [通用说明](../../i18n/README.md)。

+# 通用国际化
+
+本功能从 `v0.26.0-preview` 提供。`i18n` 可以单独用于 CLI、后台任务、通知或 Web 服务，不依赖 App、HTTP、错误目录、数据库或前端框架。业务文案、启用语言和用户偏好由接入项目维护。
+
+模块没有全局当前语言、全局可变词典或自动文件扫描。词典构建后只读，支持多个实例、多个命名空间和并发调用。完整可运行示例见 [examples/i18n](../examples/i18n/README.md)，生成契约见 [i18n.api](../examples/contracts/i18n.api)。
+
+## 独立使用
+
+```go
+bundle, err := i18n.New(i18n.Config{
+    SourceLocale: "en", DefaultLocale: "en",
+    Locales: []string{"en", "zh-Hans"},
+},
+    i18n.Document{Version: 1, Namespace: "common", Locale: "en",

+```
+
+`Render` 显式接受语言。也可以用 `WithLocale(ctx, locale)` 和 `RenderContext`，语言只属于该上下文。任务消费者需由项目显式取得接收者语言；Go context 不会自动跨进程或写入队列。
+
+`Result` 提供文本、匹配后的请求语言、实际词典语言和是否发生回退。缺键、缺参、类型错误、渲染限额返回 `*Diagnostic`；核心不决定 HTTP 状态，也不把任意错误自动转换成业务错误。诊断没有参数值、内部原因或原始文案。
+
+## 语言选择与回退
+
+- `SourceLocale` 是定义消息和参数的语言，可以只用作最终回退而不对用户开放。
+- `DefaultLocale` 是无合适偏好时的选择，必须在 `Locales` 中。
+- `Locales` 是有序的启用语言。`Match` 使用 `x/text/language` 的 BCP 47 匹配，返回真实配置的词典标签；不会用匹配器生成的带扩展标签直接索引文件。
+- `Fallbacks` 是显式、有序、无环的关系。先查选中语言，再深度优先查配置的回退；然后查默认语言及其回退，最后查源语言，过程中去重。不会从文件名或地域字符串猜一条词典继承链。
+- 非法请求偏好忽略并使用可用偏好或默认语言；非法配置、重复规范化语言、回退循环在 `New` 时失败。
+
+运行时允许部分语言缺词，`Check` 单独列出各启用语言缺少的直接翻译。CI 可因此失败，在线请求仍使用回退。存在但格式损坏的译文在构建时拒绝；替换词典应先构建新实例，成功后由项目替换实例。
+
+## 文案资源 v1
+
+```json
+{
+  "version": 1,
+  "namespace": "notifications",
+  "locale": "en",
+  "messages": {
+    "unread": {
+      "params": {"count": "integer"},
+      "value": {
+        "plural": "count",
+        "cases": {
+          "=0": {"text": "No unread messages"},
+          "one": {"text": "{count} unread message"},
+          "other": {"text": "{count} unread messages"}
+        }
+      }
+    }
+  }
+}
+```
+
+同一命名空间的同一键只有一份源定义。译文省略 `params` 时继承源定义；重复声明时必须完全一致。参数是消息级契约：各语言使用相同参数集合，分支可以不使用其中某个参数，但整条消息的所有分支合起来必须使用全部参数。
+
+`value` 支持：
+
+- `text`：命名插值 `{name}`，`{{`、`}}` 表示字面花括号；空字符串是合法译文。
+- `literal: true`：文本原样保留，适用于已有固定消息。插入参数不会再次解析，也不会自动查词典。
+- `select`：根据 string/boolean 参数选择命名分支，必须有 `other`。
+- `plural`：根据 integer/number 参数选择基数复数分支，必须有 `other`；先匹配 `=0` 等精确 int64 分支，再匹配 `zero/one/two/few/many/other`。可与 select 嵌套。
+
+复数规则固定为 [Unicode CLDR JSON 46.1.0](https://github.com/unicode-org/cldr-json/blob/46.1.0/cldr-json/cldr-core/supplemental/plurals.json)。Go 和浏览器使用同一份规则，导出包携带实际语言及回退语言的规则，避免浏览器自带规则版本不同。数据来源和许可见 [cldr](cldr/README.md)。规则版本与文案格式版本分别记录。
+
+参数类型：
+
+| 类型 | Go 调用 | 浏览器调用 |
+| --- | --- | --- |
+| `string` | 字符串 | string |
+| `boolean` | bool | boolean |
+| `integer` | int/int32/int64 等整数，或精确的 json.Number；范围为 int64 | 安全整数 number、bigint 或十进制整数字符串；超范围拒绝 |
+| `number` | 有限 float32/float64 或 json.Number | 有限 number |
+
+Number 按规范化数值处理：`1.0` 与 `1` 等价，负零显示为 `0`，不保留输入小数位数。整数不会经过 float64；不接受任意对象、Stringer、nil、自动字符串转数值。日期、货币、精度敏感的小数和字段标签可由项目显式格式化为字符串参数，时区与币种不会从语言推断。
+
+v1 的范围是普通文本、命名参数、select 和基数复数，不宣称兼容完整 ICU MessageFormat；不含 ordinal、紧凑数字格式、HTML 执行或任意表达式。复数计算使用普通数值，CLDR 的 compact-number `c/e` 操作数为 0。字段文案可以先显式 Render 后再作为参数；用户输入和业务数据保持原样。
+
+## 加载、覆盖与资源限制
+
+`LoadFS(fs.FS, paths...)` 读取明确列出的 JSON 文件，支持 `embed.FS` 和 `os.DirFS`。`DecodeJSON` 可用于业务自己取得的内存数据，拒绝重复键、未知字段、无效 UTF-8、超深结构。它们不展开 `${...}`，不执行项目代码，不自动拉远程词典。文件系统实际访问范围由传入的 FS 决定。
+
+项目已有配置加载器可加载 `i18n.Config` 的语言设置，词典正文用本包加载；避免配置加载器把词典里的 `${...}` 解释成环境变量。数据库或远程词典由项目读取为 Document，再调用 New。
+
+同一语言、命名空间可拆成多个文件；重复键默认报错。`Overlay(base, override)` 明确替换完整消息并返回独立副本，再传给 New 校验；不隐式合并分支或参数。项目决定覆盖的先后顺序。
+
+主要限额：每个 JSON 文件 1 MiB、LoadFS 总量 4 MiB、最多 1024 个文档、64 个资源语言、128 个命名空间、10000 条消息、每条 64 个参数、单文本/字符串参数 64 KiB、模式深度 24、渲染结果 1 MiB。导出的单语言包最多 4 MiB，可按命名空间拆分。
+
+`Config()`、`Documents()` 和 `Schema()` 返回独立副本；`Config.Validate()` 可预检语言配置。运行时没有修改词典的方法。
+
+## 接入 go-omni 错误与 HTTP
+
+```go
+// 项目自己的 Catalog，既有 status/code/message/params 继续维护在这里。
+catalog = errori18n.Bind(catalog, "accountErrors")
+sourceDocuments, err := errori18n.Source(catalog, "en")
+// 把 sourceDocuments 与项目加载的译文一起传入 i18n.New。
+// Bind 不修改输入；已有显式 translation 引用保持。
+
+languagePolicy, err := httpi18n.New(bundle)
+localizer := errori18n.New(bundle, nil) // 第二参数可提供并发安全的诊断回调。
+if err := localizer.Validate(catalog); err != nil { return err }
+
+app := omni.New(
+    omni.WithErrors(catalog),
+    omni.WithLanguagePolicy(languagePolicy),
+    omni.WithErrorLocalizer(localizer),
+    // 继续传入项目自己的 WithResponse / WithResponseEncoder。
+)
+```
+
+也可在单项 Definition 或 `.api errorCatalog` 条目明确声明：
+
+```json
+"translation": {"namespace":"accountErrors", "key":"username.invalid"}
+```
+
+翻译引用与逻辑错误标识、对外业务码分别独立。不同目录可以为同名错误配置不同引用；多个错误引用同一源消息时，Source 会拒绝不一致的源文案或参数。Go 源目录通过 Source 导出，保留原固定文案的字面花括号，不包含状态、业务码、example 或 cause。
+
+HTTP 策略在应用中间件之前选语言，默认读取有界 `Accept-Language`，保留请求上下文中显式设置的语言优先级。`httpi18n.WithResolver` 可替换语言来源，并显式声明缓存 Vary 所需的头；无头可声明的个性化来源自动标记 private。HTTP 策略不会读取用户数据库、JWT 或 Cookie 中的业务字段，也不自动设置可能与逐词回退不符的 Content-Language。独立标准 HTTP 可以用 `Policy.Wrap`。
+
+自定义 Resolver panic 时按无偏好处理，继续使用显式上下文语言或默认语言，避免偏好查询故障中断业务请求。项目可在自己的 Resolver 中记录诊断。
+
+错误适配器先使用原有规则解析业务错误，只替换展示文案；缺资源、适配失败保持原文，参数调用错误仍遵循原有 INTERNAL_ERROR 处理。没有 translation 引用的条目保持原行为。标准响应的平铺字段、嵌套 `${message}`、RawJSON 错误、旧 Messages 校验、路由独立目录、认证提前返回和缓冲克隆均保留原语义。
+
+`response.Result.Message` 继续是契约原文；新增 `MessageOverride` 和 `PublicMessage()`。内置 Formatter 使用最终公开文案。自定义 Encoder 需要翻译时显式使用 `PublicMessage()`；固定回执继续由 Encoder 决定。`c.JSON/Text/XML/Bytes` 等直接输出不自动重写。
+
+失败快照保存当次展示文案。幂等重放保留首次响应和失败元数据，不重新翻译，不把语言加入业务幂等键。`Localizer.Localize(ctx, registry, resolvedError)` 也可供非 HTTP 入口使用；返回值只包含文本和是否应用，不修改传入错误。
+
+生成器识别 translation 元数据并写入 Catalog、路由目录和 OpenAPI；已有无 translation 的契约不变。新 metadata 的远程 runtime 下限为 `v0.26.0-preview`，CLI 和框架使用同版；开发框架时可以显式使用本地 checkout。生成到不具备能力的旧依赖会在写入前失败。
+
+## CLI 提取、检查与导出
+
+下面的命令在框架根目录可以直接运行；安装后的 CLI 把 `go run ./cmd/go-omni` 换成 `go-omni`。
+
+```sh
+go run ./cmd/go-omni i18n check --config examples/i18n/config.json \
+  --resource examples/i18n/locales/ui.en.json \
+  --resource examples/i18n/locales/ui.zh-Hans.json
+
+go run ./cmd/go-omni i18n export --config examples/i18n/config.json \
+  --resource examples/i18n/locales/ui.en.json \
+  --resource examples/i18n/locales/ui.zh-Hans.json \
+  --locale zh-Hans --namespace ui
+
+go run ./cmd/go-omni i18n types --config examples/i18n/config.json \
+  --resource examples/i18n/locales/ui.en.json \
+  --resource examples/i18n/locales/ui.zh-Hans.json --namespace ui
+
+go run ./cmd/go-omni i18n extract --go examples/i18n/main.go
+```
+
+- `check` 检查资源和直接翻译遗漏，非空诊断退出非零；可重复提供 `--go` 检查静态引用。
+- `extract --go` 识别 Go 中 `i18n.Ref` 的字符串字面量及 import 别名；动态引用、非字面量 Render 调用和 dot import 会报告，不能声称完成任意 Go/JS/模板的静态分析。提取命令输出发现结果，check 把未解决动态引用视为诊断。
+- `extract --catalog exported-errors.json --namespace errors --locale en` 读取已有错误目录导出物，生成单个源语言 Document，不执行项目 Go。目录可以由已有 workspace Go Catalog 导出流程产生。
+- `export` 显式选择命名空间，输出一个选中语言及全部回退资源的 Pack，不输出业务错误元数据。可重复 `--namespace`。
+- `types` 输出按 namespace/key 分层的 TypeScript 参数类型及 Translate 类型，不强制 Go 命名风格，不把 int64 简单降成 number。
+
+这些命令只读输入并输出 stdout，没有自动覆盖业务文件、扫描其他项目、翻译服务调用或安装前端依赖。`Bundle.Export`、`TypeScript` 提供相同的库入口。
+
+## 前端
+
+见 [browser](browser/README.md)。运行时是普通 ES module，带 TypeScript 声明，可按项目需要复制进前端或通过 `browseri18n.Files()` 提供静态文件。语言包按需加载、先验证再提交；连续切换只有最新选择能生效，失败保留已提交语言。没有 DOM、localStorage、表单或业务请求的隐式操作。
+
+升级本模块时必须一起验证资源格式、规则版本、前后端一致性、错误兼容和生成消费者。现有项目不启用这两个适配选项时，响应与错误行为保持原样。

+# 浏览器运行时
+
+`runtime.mjs` 是可独立导入的 ES module，`runtime.d.mts` 提供类型。需要支持 ES modules、BigInt、TextEncoder 和 structuredClone 的现代浏览器；Node.js 22 用于本仓库验证。复数规则来自导出包，与 Go 共用固定 CLDR 数据，不调用浏览器自己的 Intl.PluralRules。语言选择使用包中 `locales` 的精确标识，不由浏览器再次改写别名或推断回退链。
+
+```js
+import { createLanguageController, fetchPack } from './runtime.mjs';
+
+const urls = { en: '/locales/en.json', 'zh-Hans': '/locales/zh-Hans.json' };
+const language = createLanguageController(
+  await fetchPack(urls.en),
+  locale => fetchPack(urls[locale])
+);
+
+await language.setLanguage('zh-Hans');
+const text = language.current.t('ui', 'greeting', { name: 'Alex' });
+```
+
+`current.render` 额外返回实际语言和 fallback 标记。`setLanguage` 成功提交返回 true；被更新选择取代返回 false；最新加载失败抛错并保留 current。甚至“切回当前语言”也会取消旧请求的提交资格。未知语言、错误语言包、参数 schema 或启用语言集合变化都不能提交。
+
+`fetchPack` 检查 HTTP 状态和 4 MiB 限额，支持 AbortSignal 和自定义 fetch。加载资源、鉴权、缓存策略与 URL 映射由调用者决定。它只返回 JSON 数据，`createLocalizer` / controller 负责完整资源检查。
+
+`overlayPack(pack, documents)` 显式覆盖已导出键的完整消息并重新校验，不修改输入，不允许改变参数契约。例如替换品牌标题；覆写源消息时保留原 params。业务可在 loader 返回之前应用 overrides。
+
+```ts
+import type { Translate } from './messages.generated';
+const t: Translate = language.current.t;
+// t('ui', 'greeting', { name: 'Alex' })
+```
+
+应用需要在切换成功后重新取得 current.t。视图使用 textContent 或框架的文本绑定，动态参数不递归解析、不作为 HTML 执行。金额格式化、RTL 布局、表单、路由、业务提交和偏好持久化属于应用；运行时不重建页面或重新发业务请求。
+
+完整表单示例：[examples/i18n](../../examples/i18n/README.md)。验证：

+# Pinned cardinal plural data
+
+`plurals.json` is copied without modification from Unicode CLDR JSON **46.1.0**:
+
+https://github.com/unicode-org/cldr-json/blob/46.1.0/cldr-json/cldr-core/supplemental/plurals.json
+
+The upstream data identifies CLDR version 46 / Unicode 16.0.0. See the accompanying
+Unicode license. No data is downloaded at application startup or during generation.
+
+Both Go and the browser evaluate these same rules. Browser packs include only the
+rules for the exported language and its fallback chain, together with the Unicode
+license. They do not depend on the
+browser's built-in `Intl.PluralRules` data version. Language-tag matching is a
+separate responsibility provided by `golang.org/x/text/language`.
+
+When updating this data, update `PluralRulesVersion`, preserve the license, and run
+the upstream-sample and Go/browser conformance tests. This version supports cardinal
+rules for ordinary numbers; compact-number operands `c`/`e` are zero. Ordinal and
+compact-number formatting are not part of the v1 message format.

 手写项目使用 `lifecycle.NewRuntimeWithConfig(ctx, cfg)`；完成 HTTP 排空后调用 `runtime.Finish(runErr)`。库本身不执行 os.Exit。

+### HTTP 请求与依赖的关闭屏障
+
+App 统计已进入且尚未退出的整个处理链，包括中间件、响应编码和 defer；停止接收与登记请求共用同步屏障。关闭连接、取消 context、HTTP/2 session 结束均不等于处理链结束。
+
+`RunContext` / `ServeContext` 先按 `shutdownTimeout` 排空，超时取消并关闭连接；App 随后按 `http.shutdownCancelTimeout`（零默认 5s）等待处理器完成收尾。收尾成功则执行逆序 OnShutdown，仍保留原排空超时错误。收尾窗口结束时还有处理器运行，则永久返回 `ErrResourcesRetained` 并跳过所有 OnShutdown；后续 Close 或晚到的处理器返回不会触发补做清理。
+
+`Runtime.Finish(runErr)` 收到该错误后，继续执行后台 OnStop/OnDrain 并取消 WorkContext，但跳过 OnClose；后续 `Runtime.Close` 也保持资源保留。生成入口通过这条错误链保留数据库等共享依赖和借用日志，并非零退出。手写入口必须传递 runErr 给 Finish，并在 `errors.Is(runErr, lifecycle.ErrResourcesRetained)` 时跳过自己拥有的额外资源清理，不能无条件 defer DB.Close/Logger.Close。
+
+`App.Close` 本身会停止接收、取消请求并等待收尾，适用于外部 HTTP 宿主；正常优雅排空应先由宿主停止监听并 Shutdown，再调用 Close。不要在请求处理器或清理钩子内部调用 Close（会等待自身）。`App`、`Engine`、`NewServer().Handler` 和 `RunWith` 都经过统计；已停止的 App 返回简单 503，不再调用可能使用已关闭依赖的中间件或编码器。App 不支持关闭后重新启动。
+
+外部 Runner 返回不构成请求完成证明，App 仍执行自己的完成屏障；Runner 负责关闭自己拥有的 listener/连接。原始 `Router().ServeHTTP` 绕过 App。处理器退出后继续运行的自建 goroutine、Hijack/WebSocket 后台工作，必须用 OnStop/OnDrain 注册，框架不会推断这些工作的生命周期。HTTP/2 低层 Shutdown 也会等待独立 handler goroutine；超时返回 error 仍不表示它已退出。
+
+新行为增加一个有限 HTTP 收尾窗口，调用方总停机预算应计入它。已有生成项目升级框架即可获得 Runtime.Finish 的保护；重新生成可同步入口注释。可运行示例见 [httpSafety](../examples/httpSafety/README.md)。

 ### 升级

 v0.14.x 受管理项目将 module 和 CLI 一起升级到 v0.15.0-preview，再运行 `go-omni api generate`、`go-omni api generate --check` 和业务测试。生成器更新 main/runtimeGen，保留 svc、Logic 和配置。已有配置不添加新字段也会使用默认时限，需要调整时再编辑 yaml。

+## 兼容边界
+
+旧 nethttp 手写普通路由新增默认 8 MiB 限额，大请求应显式配置；生成契约默认 1 MiB 保持。取消后的等待默认 5s，需计入服务停机预算。手写资源拥有者须将运行错误传给 Runtime.Finish，并在资源保留信号下跳过自己的额外关闭操作。自建 goroutine、Hijack 后的工作仍须登记后台生命周期。
+
+自定义 Runner、独立 native/http2.Server、反向代理的额外限额由各自拥有者配置；使用 WithTransport 获取统一装配。请求体、multipart 单文件和幂等缓存限额保持各自用途。已发送的流式响应无法撤回，先完成有界读取再执行业务。

+环境：macOS / Apple M2 Max，Go 1.27.1，Node.js 22.15.1，TypeScript 5.6.3；最低版本另用 Go 1.22.12 核验。TypeScript 编译器通过 npm 临时缓存使用，没有添加项目 npm 依赖。
+
+| 验证 | 结果 |
+| --- | --- |
+| `go test -race ./...` | 54 个有测试的包通过；未启用集成环境变量的生成消费者单独执行如下 |
+| `go vet ./...`、`go build ./...`、`git diff --check` | 通过 |
+| `GO_OMNI_SCAFFOLD_INTEGRATION=1 go test ./cmd/go-omni/apigen -run 'TestI18nGeneratedConsumer\|TestErrorInheritance\|TestErrorParamsConsumer' -count=1 -v` | 3 组真实生成项目生成、重复生成、check 和消费者 race 测试通过 |
+| Go 1.22.12：`go test ./i18n/... ./app ./errors ./response ./httpx ./config ./cmd/go-omni ./examples/i18n` | 全部通过 |
+| Go 1.22.12：开启集成测试，`go test ./cmd/go-omni/apigen -run TestI18n -count=1 -v` | translation 元数据边界、真实生成消费者通过 |
+| `node --test i18n/browser/runtime.test.mjs` | 4 组通过，包含覆盖、并发切换、最新失败/过期请求、坏包与读取上限 |
+| `TestPinnedCLDRSamples` | 5,777 个上游普通基数规则样例端点通过；不把省略号和紧凑数字样例计入 |
+| `TestBrowserConformance`、`TestSourceLocaleCanBeFallbackOnly` | Go 导出包在 Node 中执行，中文/英文/俄文/阿拉伯文/法文、精确 int64、小数、回退与源语言未启用通过；cmn 别名及私用标签不由浏览器改写 |
+| `TestTypeScriptConsumer`（PATH 提供 tsc） | strict / ES2022 / NodeNext 编译通过；缺参、错类型、多余参数、未知键/命名空间必须产生编译诊断 |
+| `go test ./i18n -run '^$' -fuzz FuzzDecodeJSON -fuzztime 10s` | 419,121 次执行通过 |
+| 示例 CLI、词典 check、示例 HTTP 测试 | 通过；示例中英文输出及中文错误 HTTP 409 / code 400001 保持 |
+
+最后的 TypeScript 类型修正后，重新执行了 `i18n/...`、CLI、示例 race 测试及对应 Go 1.22 验证。核心一致性及类型验证可复现为：
+
+```sh
+npm exec --yes --package typescript@5.6.3 -- go test ./i18n \
+  -run 'TestTypeScriptConsumer|TestPinnedCLDRSamples|TestBrowserConformance|TestSourceLocaleCanBeFallbackOnly' \
+  -count=1 -v
+```
+
+原始日志见 [i18nValidation.txt](i18nValidation.txt)。
+
+## 兼容和隔离覆盖
+
+- 多 Bundle、多 App、并发请求与多个命名空间不共享可变语言状态；构建输入与导出快照修改不影响实例。
+- 项目目录和路由独立目录同名错误正确选取各自翻译；固定旧文案的字面花括号保留。
+- 翻译仅进入展示层。HTTP 200 业务失败、HTTP 409/401/500、int64 业务码、嵌套响应模板、旧 Messages 校验、RawJSON 错误、认证提前返回、panic、缺参数和缓冲桥接均有回归。
+- 参数值不重新解释为模板，内部 cause 不进入响应；Localizer 或偏好 Resolver panic 不把语言故障传播成新的业务执行结果。
+- 自定义固定回执由原 Encoder 控制；直接 Text/JSON 等输出不自动改写。自定义 Encoder 可显式采用 PublicMessage。
+- 本地/共享幂等重放保留首次响应，即使后续请求语言不同也只执行业务一次。
+- 资源严格校验、循环回退、参数契约不一致、缺键诊断、显式覆盖、CLI 输入不被改写、旧 runtime 能力门槛均有测试。
+
+## 浏览器实测
+
+使用独立示例启动本机 `127.0.0.1:8098`，执行了：
+
+1. 输入测试草稿，从英文切为中文：草稿保留，提交次数为 0。
+2. 点击提交：次数变为 1。切回英文：草稿保留，次数仍为 1。
+3. 停止示例服务后再选择中文：显示加载失败，仍停留在英文，草稿和一次提交保留。
+
+示例服务和临时浏览器页面已关闭。乱序和快速重复选择由浏览器运行时自动测试验证。
+
+## Go 1.22 发布前兼容性修复
+
+初轮全仓 Go 1.22 验收暴露了两处旧问题，发布准备阶段已修复：
+
+- 共享 Go 目录测试工程的 go.mod 从 1.24.0 调整为框架声明支持的 1.22.0，远程验收的同类测试工程同步调整。
+- JSON 对象/数组结束定界符读取失败时保留底层错误，外层 MaxBytesReader 的限额错误继续被识别为 HTTP 413。新增对象、数组、嵌套结构的 reader cause 回归，原有 limit=0/1/4 测试保留。
+
+最初发现问题的日志仍保留在 i18nValidation.txt 中，便于追溯；发布前的最终结果单独记录在 i18nReleaseValidation.txt 中。
+
+## 发布前最终验收
+
+- `GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race ./...`：54 个有测试的包通过，包含实际生成消费者；PATH 提供 TypeScript 5.6.3，跨端和类型测试实际执行。
+- `GOTOOLCHAIN=go1.22.12 GO_OMNI_SCAFFOLD_INTEGRATION=1 go test ./...`：全仓通过，先前两处失败已消除。
+- `go vet ./...`、`go build ./...`、浏览器运行时测试、发布脚本语法检查、`git diff --check`：通过。
+- `python3 scripts/verifyManagedProject.py --report reports/i18nManagedLocal.json`：真实生成项目运行、构建、重复生成、nethttp/native 信号退出、上传下载与故障清理通过；临时进程已清理。[机器记录](i18nManagedLocal.json)。
+
+完整最终输出见 [i18nReleaseValidation.txt](i18nReleaseValidation.txt)。发布后从空 module 缓存安装固定标签的验收也已通过，见文末；远程报告独立提交，不移动发布标签。
+
+## 性能与发布边界
+
+`BenchmarkRender` 对俄文基数复数、22 参数的单条消息，当前机器一次测量为 3,753 ns/op、1,040 B/op、27 allocs/op；这只是开发机样本，不代表 SLA 或与旧实现的性能对比。
+
+本次按 Go module 标签 `v0.26.0-preview` 发布；浏览器运行时随 module 分发，没有单独发布 npm 包。CLDR 46.1.0 数据随源码和导出包携带许可，启动不下载规则。v1 支持普通文本、命名参数、select 和基数复数；不是完整 ICU MessageFormat，不自动处理金额、日期、时区、RTL 布局或业务字段翻译。
+
+## 已发布远程产物验收
+
+`v0.26.0-preview` 标签固定在 `d1a747c36f15d964dd445d661623b68a45892adf`；远程 Go module 校验和为 `h1:9Ao/6+8jdqXf4Ia++rhgorTrYclAgrWgXw3U+AWtB4I=`。发布代码与标签已推送，验收记录独立提交，标签没有移动。
+
+使用空 module 缓存安装已发布 CLI，10 组真实生成消费者、87 项发布检查通过，耗时 83.76 秒。CLI 与框架固定同版，所有消费者均确认无本地 replace。新检查覆盖下载模块中的独立 i18n、HTTP 错误不变量、源语言仅回退、CLDR 及 Go/浏览器一致性、TypeScript strict 消费者、四个 CLI 子命令和浏览器切换竞态/失败保留。详见 [i18nRemote.json](i18nRemote.json)。
+
+复验命令（需要 Node.js，TypeScript 由 npm 临时缓存提供）：
+
+```sh
+npm exec --yes --package typescript@5.6.3 -- python3 scripts/verifyManagedRelease.py \
+  --version v0.26.0-preview --report reports/i18nRemote.json

 Outcome 只属于当前受管理事务；回调不得自己提交/回滚、执行隐式提交 SQL、把事务交给其他 goroutine。其他连接、独立事务、非事务表、文件和第三方系统的副作用由业务负责。

 标准库异步回滚不公开的驱动原因无法还原。只拿到 ErrTxDone 时保守返回 Unknown；直接观察到的回滚失败全部保留。panic/Goexit 保持原有传播，没有普通返回值可携带回滚原因。返回错误的文本/具体最外层类型有变化，调用方使用 errors.Is/As；GORM 自己的 Transaction 不属于本次接口。
