 业务需要临时链接时显式依赖额外接口 `storage.Presigner`。S3/OSS 实现 `PresignGet`；Local 用 `storage.NewSigner(files, downloadBaseURL, secret)` 提供 HTTP 下载 Handler。链接 TTL 为 1 秒到 1 小时，私钥/临时凭据可能让云链接提前失效。签发链接前必须完成业务授权；对象 key 及 bucket 本身不是租户权限。签名链接不要写日志。受限直传和云端分片现已提供可选接口，见 [上传与续传说明](storage/README.md)。生命周期、ACL、CDN 自定义域名和版本管理仍由平台/部署管理。
 
+需要 inline 预览、显示文件名或指定响应 MIME 时，使用可选 `storage.ReadPresigner.PresignGetWithOptions`，返回 URL 和签名内的实际到期时间。Local、S3/R2、OSS 使用相同选项；Local 支持 HEAD 与范围读取，云端由原生存储服务处理。旧下载接口不变，见 [签名读取说明](storage/README.md#签名预览与下载)和[完整示例](examples/signedRead/README.md)。

 R2 实现 S3 的子集，配置入口使用标准账户 endpoint；法域专属 endpoint 可显式配置。兼容性依据：[R2 S3 API](https://developers.cloudflare.com/r2/api/s3/api/)、[R2 签名链接](https://developers.cloudflare.com/r2/api/s3/presigned-urls/)。OSS 使用其[官方 Go SDK v2](https://www.alibabacloud.com/help/en/oss/developer-reference/manual-for-go-sdk-v2/)，没有假定全部 S3 行为与 OSS 等价。

+
+范围是 `.api` 的响应类型。递归请求 DTO（包括间接包含递归类型的请求）仍不支持，`contract.New/Describe` 与手写 `openapi.SchemaOf` 的限制不变；它们不会自动获得递归请求绑定能力。直接值递归如 `Child Node`、仅由值字段形成的相互递归，以及字段组合循环仍会报错。业务返回值必须是可序列化的有限数据，不能构造对象指针环。

+新增通用签名读取选项：预览或下载、显示文件名和 MIME 类型，由调用方选择。`PresignGetWithOptions` 返回 URL 与签名内的到期时间；原 `PresignGet` 默认下载、第三方原有接口和旧本地链接继续兼容。有效期仍是 1 秒到 1 小时，不增加撤销或业务分享机制。
+
+Local、S3/R2、OSS 使用同一接口，所有选项参与签名。中文文件名采用标准编码，拒绝 CR/LF 等非法头内容。本地支持 HEAD、单段/多段 Range、206/416 与条件请求，按真实内容范围流式输出；过期与篡改在读取文件之前拒绝。

+# API 与通用工程混合工作区
+
+本例只定义生成工程的类型与目录，不包含业务模型、外部服务或特定调度方式。使用 v0.30.0-preview 或更新版本 CLI。
+
+下面从一个空目录创建两个独立 Go module；API 工程来自 API 模板，通用工程默认不监听端口。
+
+```sh
+go install git.yuntuo.hk/k2safe/go-omni/cmd/go-omni@v0.30.0-preview
+mkdir mixed-demo
+cd mixed-demo
+go-omni api new apps/interface --module example.com/interface
+go-omni project new apps/program --module example.com/program
+```
+
+将本目录的 `omni.workspace.json` 复制到 `mixed-demo` 根目录，然后执行：
+
+```sh
+go-omni workspace format    # 格式化 API 契约；通用工程显示 SKIP
+go-omni workspace generate
+go-omni workspace check
+```
+
+也可以省略两个 `kind`：CLI 根据各工程的生成清单识别。显式声明与清单冲突会报错；不会根据目录名称猜测类型。
+
+Go 多模块编译由 Go 工具链独立管理：
+
+```sh
+(cd apps/interface && go mod tidy)
+(cd apps/program && go mod tidy)
+go work init ./apps/interface ./apps/program
+go test ./apps/interface/... ./apps/program/...
+go build ./apps/interface/... ./apps/program/...
+```
+
+workspace check 不修改 `go.work`、`go.mod`、`go.sum` 或项目源文件；不启动应用。若显式配置了共享错误目录提供方，仍会按既有约定构建并调用该 Go 导出函数，见 [目录导出规则](../../DEVELOPMENT.md#同一份-go-错误目录供多个服务生成)。
+
+手工修改任一生成的 `main.go` 后，workspace check 会报告对应工程失败并返回非零退出码；两个工程都存在问题时，会汇总报告。workspace generate 先预检所有工程，再进行各自的文件事务；一个预检失败时，其他工程也不写入。不承诺多个模块之间的崩溃事务性。
+
+本例命令与 `go.work` 编译流程由 `cmd/go-omni/TestMixedWorkspaceConsumer` 在本地和远程发布验收中执行。

+
+按启动日志显示的监听地址访问 `/tree`、`/forest`、`/optional`、`/raw`、`/pair`。前三层节点通过 `[]types.Node` 编译和返回；`/optional` 返回 null，`/raw` 直接返回节点，`/pair` 返回相互引用类型的有限实例。`docs/openapi.json` 中的 `DTO_Node` 通过 `$ref` 引用自身，`DTO_Branch`、`DTO_Leaf` 互相引用。

+这个离线示例使用标准库 `httptest`，不连接网关、数据库或外部 Collector。它把 `X-Trace-Id`、`X-Span-Id` 和 `X-Request-Id` 配置给通用 `telemetry.HeaderPropagator`，再通过 `app.Use(runtime.Middleware())` 进入服务。业务 Handler 只读取 `logx.TraceID` / `logx.RequestID`，不解析 Header。
+
+`HeaderPropagator` 同时支持标准 W3C `traceparent`；两种格式同时存在时优先 W3C。出站请求使用 `telemetry.Transport` 时会注入 W3C 和配置的兼容 Header。旧项目不配置它时，go-omni 仍只使用默认 W3C 传播。
+
+示例中的 ID 是固定测试值。生产环境只有在网关或受信代理已经校验这些 Header 时才启用兼容传播；Trace ID/Span ID 不是认证凭据，也不能用于授权、幂等或租户隔离。自定义 Header 不携带采样标志，适配器会把有效的成对 ID 视为已采样；需要保留上游采样决定时应使用 `traceparent`。

+- `GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -count=1 ./...`：通过，包含生成器、生命周期、存储、i18n、telemetry 和离线示例。
+- `go test -race ./telemetry ./examples/telemetryHeaders`：通过。
+- `GO_OMNI_SCAFFOLD_INTEGRATION=1 GOTOOLCHAIN=go1.22.12 go test -count=1 ./...`：通过。
+- `go vet ./...`、`go build ./...`、`git diff --check`：通过。
+- `go run ./examples/telemetryHeaders`：通过，示例打印固定 Trace ID、Request ID 和 JSON 响应。
+- 发布后空模块缓存验收：`verifyManagedRelease.py` 通过 110 项，`verifyProgramRelease.py` 通过 30 项，`verifyWorkspaceRelease.py` 通过 16 项；三份结果分别见 `headerPropagationRemote.json`、`headerPropagationProgramRemote.json` 和 `headerPropagationWorkspaceRemote.json`。
+
+完整竞态套件在高并发生成器生命周期用例中出现了已有的时序超时（`TestGeneratedMainLifecycle/drainBeforeClose`、`TestGeneratedBackgroundPhases/nethttp`）；单独重跑受影响的 `TestManagedGeneratedProject` 通过，功能定向竞态测试通过，未发现本次 Header 传播相关竞态。
+
+## 代码边界
+
+- 默认 `telemetry.Config` 仍使用 W3C 传播，未配置新适配器的项目行为不变。
+- `telemetry.Transport` 在兼容模式下同时注入 W3C 与配置 Header，调用方请求对象不会被修改。
+- 无效 ID、重复 Header 名称以及试图覆盖 `traceparent` / `tracestate` 的配置会被拒绝或忽略。
+- 不增加认证、租户、幂等、业务重试或网关依赖。

 ## 远程发布验收
 
-发布后运行 `scripts/verifyProgramRelease.py` 与原有 `scripts/verifyManagedRelease.py`，使用空模块缓存安装固定远程 CLI，禁止本地 replace。结果在完成后补入本文件及 JSON 报告。
+2026-09-30，两个独立空模块缓存安装远程 v0.28.0-preview，均未使用本地 replace：
+
+- [通用工程远程报告](programRemote.json)：30 项检查通过，耗时 26.45 秒。测试直接从下载的框架模块运行，并通过远程 CLI 生成实际消费者；包含示例的一次性运行。
+- [既有生成项目远程报告](programManagedRemote.json)：98 项检查、10 组消费者通过，耗时 111.07 秒。覆盖原有配置、HTTP 关闭、上传策略、国际化及 TypeScript 消费者；TypeScript 5.6.3 通过 npm exec 提供，未跳过该检查。
+- 两组报告的远程模块 checksum 一致：`h1:nD9Xtn7RhHy81n+qp96rlcJlxpDc276Per+dt1low1g=`。
+- 发布标签固定在代码提交 `0b6c0043b6c3b58648645aeee03bf80801e6aa3f`；标签对象 `50caea1fc81a52080c0f0832d8c4a63cac786859`。代码与标签已推送，验收文档随后独立提交，不移动发布标签。

+# v0.29.0 通用签名读取验收
+
+范围：Local、S3/R2、OSS 的签名读取选项和本地范围读取。接口不包含业务身份、租户、分享记录、数据库、撤销或固定有效期。旧 Presigner、旧本地链接和默认下载行为兼容。
+
+## 本地回归
+
+2026-09-30，macOS arm64，Go 1.27.1：
+
+- `GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race -count=1 ./...`：57 个测试包通过，apigen 集成包 123.143 秒。
+- `GOTOOLCHAIN=go1.22.12 GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -count=1 ./...`：57 个测试包通过，apigen 集成包 113.212 秒。
+- `go vet ./...`、`go build ./...`、`git diff --check`：通过。
+- `go run ./examples/signedRead -check`：真实回环 HTTP 预览、中文文件名、下载、HEAD、Range 通过。
+- `python3 scripts/verifyUploads.py --output reports/signedReadMinio.json`：真实隔离 MinIO 的新读取选项、原上传/分片与存储契约通过，见 [报告](signedReadMinio.json)和[日志](signedReadMinio.txt)。独立容器无外部网络、不映射端口，已清理，原有容器保持运行。
+
+首次 MinIO 回归中，原有契约故意发送错误长度触发 SDK 重试退避，耗尽契约的 10 秒预算。测试专用 client 改为 MaxRetries=1，与现有协议测试一致；生产 client 配置未变，修正后通过。
+
+## 覆盖内容
+
+- 默认 attachment、inline、可选 MIME、ASCII/中文/特殊字符文件名，拒绝 CR/LF、控制字符、路径、过长参数、非法 MIME 和 disposition。
+- 本地签名绑定版本、key、有效期、全部响应选项，重复参数、未知参数、签名篡改、版本剥离和旧下载 URL 注入 inline 均拒绝，拒绝前不读存储。
+- 30 分钟实际签名到期时间、TTL 上下限、精确到期边界、取消 context；过期 Range/HEAD/条件请求不得读取文件或返回缓存命中。
+- 本地真实文件 GET/HEAD 内容长度、前缀/后缀/开放区间/截断/多段范围、206/416，Seek 不暴露元数据，按范围读取而非全文件缓冲；顺序读取 Store 回退完整 200。
+- 错误及条件响应保持 private/no-store，HEAD 成功与失败均无响应体。
+- OSS SDK V1/V4 独立重新计算签名，验证响应头在签名前加入，中文文件名、配置域名、到期时间及选项篡改；拒绝未签名配置。S3/R2 验证原生 SDK 查询参数与实际到期时间。
+- MinIO 实际 GET/Range 的响应头、字节和状态正确，篡改 disposition/type/cache/expiry 被服务端拒绝。
+
+## 验证边界
+
+OSS/R2 未使用云账号实测；SDK/MinIO 验证不能代替实际桶和域名验收。OSS 默认域名可能强制下载，其响应头覆盖受平台规则限制，需部署方检查实际 200/206。
+
+浏览器控制工具不可用，隔离 Chrome/Chromium 截图尝试未获得成功渲染证据，因此不计为浏览器预览通过。真实 PDF 的 HTTP 响应已检查，浏览器视觉预览与实际云域名接入仍需项目侧回归。
+
+## 发布验收
+
+三个独立空模块缓存安装远程固定 `v0.29.0-preview`，均无本地 replace，全部通过：
+
+- [综合远程报告](signedReadRemote.json)：107 项检查、11 组生成消费者，138.76 秒。包括下载模块中的签名读取、旧链接兼容、篡改/过期、范围读取、OSS V1/V4、S3/R2 和真实 HTTP 示例，以及原有生成器、生命周期、配置、i18n 等回归。
+- [通用工程报告](signedReadProgramRemote.json)：30 项，31.82 秒。
+- [混合工作区报告](signedReadWorkspaceRemote.json)：16 项，25.55 秒。
+
+首次综合检查因生成的基础消费者未引入可选云存储 SDK，缺少相应 go.sum 条目而中止。验收脚本增加固定版本的可选适配器依赖准备后，从空缓存重跑全部通过；框架发布代码未修改。
+
+三次下载 checksum 一致：`h1:FV3AzbYWBFQ7qnF3T2FWypGv2PSecCJfcOuNa2yKzRk=`。固定标签对应代码 `f0c62152d72b1b50672c29f5191ad88f8be3eee4`。验收脚本、说明和远程报告另行提交，不移动标签。

+# v0.28.1 混合工作区验收
+
+2026-09-30，macOS arm64。范围为 CLI 工程识别与命令分发，不改变运行时接口、生成模板归属或业务规则。
+
+## 发布前回归
+
+- `GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -race -count=1 ./...`：56 个测试包通过，包含实际生成消费者。
+- `GOTOOLCHAIN=go1.22.12 GO_OMNI_SCAFFOLD_INTEGRATION=1 go test -count=1 ./cmd/go-omni/...`：5 个 CLI 包通过，含 API 与通用工程消费者。
+- `go vet ./...`、`go build ./...`、`git diff --check`：通过。
+
+## 行为覆盖
+
+- 显式 kind 与按清单自动识别，两类工程混合及纯通用工程工作区。
+- 原有无 kind 的 API 清单、首次生成时显式 api 入口保持兼容。
+- 未知类型、类型与已有清单冲突、两种清单并存、project 携带 api、错误 module、损坏清单、重复 JSON 键、越界/重叠路径与符号链接均拒绝。
+- check 汇总两个工程的生成漂移，也在一个工程身份错误时继续检查其他工程；失败与成功均不写文件。
+- format 对通用工程显示 SKIP，即使它的 Go 文件存在漂移也不修改；API 格式化规则保持。
+- 任意一类工程预检失败时，另一类工程的待补生成文件不被提前写入；所有预检通过后可补回缺失产物。
+- 手写文件、go.work、go.work.sum、各 module 的 go.mod/go.sum 保持。
+- 原有显式共享 Go 错误目录提供方在加入通用工程后仍可生成、检查，失败不改项目文件。
+- 真实 CLI 创建两个独立 module，执行混合 format/generate/check，然后用 Go 原生 go.work 完成 race 测试与多模块构建。
+- 真实 CLI 遇到两个工程漂移时汇总输出，退出码 1；失败生成保持原工作区内容，修复后可恢复生成与检查。
+
+检查只涉及生成产物，不替代业务测试。显式 errorCatalogs 仍执行受信任的 Go 导出函数；生成事务按单个工程提交，不保证跨模块的崩溃原子性。
+
+## 远程发布验收
+
+三个独立空模块缓存安装固定远程 v0.28.1-preview，均未使用本地 replace：
+
+- [混合工作区报告](workspaceRemote.json)：16 项检查通过，耗时 21.74 秒。远程 CLI 创建两类 module，完成显式/隐式类型识别、混合生成检查、真实 go.work race/构建、失败汇总与写入前预检。
+- [通用工程报告](workspaceProgramRemote.json)：30 项检查通过，耗时 25.69 秒，含真实进程退出、资源保留与手写代码保护。
+- [既有生成器报告](workspaceManagedRemote.json)：98 项检查、10 组消费者通过，耗时 108.92 秒。包含配置、HTTP 安全、国际化与 TypeScript；TypeScript 5.6.3 通过 npm exec 提供，未跳过。
+- 三组远程模块 checksum 一致：`h1:tah8kFIFZMuPK/veNBu/AjB6bdmlp5DgN+fTuNNkQmA=`。
+- 发布标签固定在代码提交 `0d2c6040e2694795f203304148dbaec00318c608`，标签对象 `e0e483b2741f92c8e44a0e45e56d78a920cb3ebb`。验收文档随后独立提交，发布标签不移动。

 没有固定业务字段、目录规则或身份模型。鉴权、对象归属、业务配额由应用定义。SDK 客户端和连接池由应用持有；适配器不会在一次调用后关闭客户端。
 
+## 签名预览与下载
+
+`v0.29.0-preview` 新增独立的可选接口 `ReadPresigner`，不扩充原 Store/Presigner，不要求第三方适配器修改代码。原 `PresignGet(ctx, key, ttl)` 和既有本地下载链接继续有效、默认 attachment。
+
+```go
+// signer 可以是 storage.NewSigner 返回的本地 Handler，或 S3/R2、OSS Store。
+link, err := signer.PresignGetWithOptions(ctx, key, 30*time.Minute, storage.ReadOptions{
+    Disposition: storage.DispositionInline,
+    FileName: "示例报告.pdf",
+    ContentType: "application/pdf",
+})
+if err != nil { return err }
+// 把 link.URL 和 link.ExpiresAt 返回给已授权的调用方。
+```
+
+TTL 仍为 1 秒到 1 小时，30 分钟无需改配置。`ReadLink` 包含 `url` 和 `expiresAt`，到期时间取自实际签名，精确到秒（不足一秒的部分舍弃）；临时云凭据可能更早失效。无需额外请求 Header，客户端直接打开 URL。可通过 `storage.ReadPresigner` 做能力判断；不支持时由调用方明确处理，不应静默降级成公开地址。
+
+`Disposition` 只接受 inline/attachment，空值为 attachment。`FileName` 是显示名，与存储 key 无关；中文使用标准 `filename*` 编码，拒绝控制字符（包括 CR/LF）、路径分隔符及超长值。`ContentType` 为空时沿用对象元数据，可显式指定合法 MIME 类型；它只控制响应，不转换或验证文件内容。PDF 应在上传时就保存 `application/pdf` 元数据。inline 请求内联显示，能否展示还取决于浏览器的格式支持与用户设置。
+
+本地签名绑定 key、到期时间、版本及全部选项，拒绝重复/未知参数和篡改；先验签、验有效期，再读取对象或处理条件请求。Local 使用受文件内容边界约束的流，GET/HEAD 的长度不包含内部元数据；支持单段/多段 Range、206/416，以及 Last-Modified 条件请求。HEAD 返回完整对象头、无响应体，忽略 Range。自定义 Store 的 Body 实现 `io.ReadSeeker` 时复用同一行为；仅支持顺序读取时返回完整 200，不宣称支持范围读取，也不把整个对象加载到内存。
+
+云端适配器在 OSS/S3 原生 SDK 签名前传入响应参数，禁止先签名后拼参数或替换域名。Range 由云存储处理；云端 GET 签名不能直接改成 HEAD 使用。新接口请求 `Cache-Control: private, no-store`，本地成功、错误及条件响应均保持该策略；云端响应头覆盖受平台规则约束，需检查实际 200/206 响应与代理缓存配置。
+
+OSS 默认域名或加速域名可能强制下载。需要自定义域名时，在应用装配 SDK client 时设置已绑定桶的域名和 `WithUseCName(true)`，再传给适配器；SDK 的区域、签名版本、凭据由应用配置。例如在现有 SDK config 上调用 `WithEndpoint("https://files.example").WithUseCName(true)`。参见 [OSS 预览规则](https://help.aliyun.com/zh/oss/how-to-ensure-an-object-is-previewed-when-you-access-the-object)与 [GetObject 响应参数规则](https://www.alibabacloud.com/help/en/oss/developer-reference/getobject)。
+
+签发权限、对象是否不可变、审计和前端链接复用由项目维护。框架不添加分享表、撤销、租户或数据库依赖；重新签发不会撤销旧链接，到期不会收回已下载内容，也不会中断已开始的传输。本地入口使用显式配置的公开 baseURL，不猜测 Host/转发头，不公开磁盘目录。应用与代理日志应隐藏查询参数。
+
+完整离线 [预览/下载示例](../examples/signedRead/README.md)，包含真实 HTTP 检查与一页 PDF。OSS V1/V4、S3/R2 SDK 签名和隔离 MinIO 有回归；OSS/R2 云账号尚未实测，部署方仍需对实际桶、域名及浏览器进行验收。
