+# @sdk/access SDK Reference
+
+The `github.com/router-for-me/CLIProxyAPI/v6/sdk/access` package centralizes inbound request authentication for the proxy. It offers a lightweight manager that chains credential providers, so servers can reuse the same access control logic inside or outside the CLI runtime.
+
+## Importing
+
+```go
+import (
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+)
+```
+
+Add the module with `go get github.com/router-for-me/CLIProxyAPI/v6/sdk/access`.
+
+## Manager Lifecycle
+
+```go
+manager := sdkaccess.NewManager()
+providers, err := sdkaccess.BuildProviders(cfg)
+if err != nil {
+    return err
+}
+manager.SetProviders(providers)
+```
+
+* `NewManager` constructs an empty manager.
+* `SetProviders` replaces the provider slice using a defensive copy.
+* `Providers` retrieves a snapshot that can be iterated safely from other goroutines.
+* `BuildProviders` translates `config.Config` access declarations into runnable providers. When the config omits explicit providers but defines inline API keys, the helper auto-installs the built-in `config-api-key` provider.
+
+## Authenticating Requests
+
+```go
+result, err := manager.Authenticate(ctx, req)
+switch {
+case err == nil:
+    // Authentication succeeded; result describes the provider and principal.
+case errors.Is(err, sdkaccess.ErrNoCredentials):
+    // No recognizable credentials were supplied.
+case errors.Is(err, sdkaccess.ErrInvalidCredential):
+    // Supplied credentials were present but rejected.
+default:
+    // Transport-level failure was returned by a provider.
+}
+```
+
+`Manager.Authenticate` walks the configured providers in order. It returns on the first success, skips providers that surface `ErrNotHandled`, and tracks whether any provider reported `ErrNoCredentials` or `ErrInvalidCredential` for downstream error reporting.
+
+If the manager itself is `nil` or no providers are registered, the call returns `nil, nil`, allowing callers to treat access control as disabled without branching on errors.
+
+Each `Result` includes the provider identifier, the resolved principal, and optional metadata (for example, which header carried the credential).
+
+## Configuration Layout
+
+The manager expects access providers under the `auth.providers` key inside `config.yaml`:
+
+```yaml
+auth:
+  providers:
+    - name: inline-api
+      type: config-api-key
+      api-keys:
+        - sk-test-123
+        - sk-prod-456
+```
+
+Fields map directly to `config.AccessProvider`: `name` labels the provider, `type` selects the registered factory, `sdk` can name an external module, `api-keys` seeds inline credentials, and `config` passes provider-specific options.
+
+### Loading providers from external SDK modules
+
+To consume a provider shipped in another Go module, point the `sdk` field at the module path and import it for its registration side effect:
+
+```yaml
+auth:
+  providers:
+    - name: partner-auth
+      type: partner-token
+      sdk: github.com/acme/xplatform/sdk/access/providers/partner
+      config:
+        region: us-west-2
+        audience: cli-proxy
+```
+
+```go
+import (
+    _ "github.com/acme/xplatform/sdk/access/providers/partner" // registers partner-token
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+)
+```
+
+The blank identifier import ensures `init` runs so `sdkaccess.RegisterProvider` executes before `BuildProviders` is called.
+
+## Built-in Providers
+
+The SDK ships with one provider out of the box:
+
+- `config-api-key`: Validates API keys declared inline or under top-level `api-keys`. It accepts the key from `Authorization: Bearer`, `X-Goog-Api-Key`, `X-Api-Key`, or the `?key=` query string and reports `ErrInvalidCredential` when no match is found.
+
+Additional providers can be delivered by third-party packages. When a provider package is imported, it registers itself with `sdkaccess.RegisterProvider`.
+
+### Metadata and auditing
+
+`Result.Metadata` carries provider-specific context. The built-in `config-api-key` provider, for example, stores the credential source (`authorization`, `x-goog-api-key`, `x-api-key`, or `query-key`). Populate this map in custom providers to enrich logs and downstream auditing.
+
+## Writing Custom Providers
+
+```go
+type customProvider struct{}
+
+func (p *customProvider) Identifier() string { return "my-provider" }
+
+func (p *customProvider) Authenticate(ctx context.Context, r *http.Request) (*sdkaccess.Result, error) {
+    token := r.Header.Get("X-Custom")
+    if token == "" {
+        return nil, sdkaccess.ErrNoCredentials
+    }
+    if token != "expected" {
+        return nil, sdkaccess.ErrInvalidCredential
+    }
+    return &sdkaccess.Result{
+        Provider:  p.Identifier(),
+        Principal: "service-user",
+        Metadata:  map[string]string{"source": "x-custom"},
+    }, nil
+}
+
+func init() {
+    sdkaccess.RegisterProvider("custom", func(cfg *config.AccessProvider, root *config.Config) (sdkaccess.Provider, error) {
+        return &customProvider{}, nil
+    })
+}
+```
+
+A provider must implement `Identifier()` and `Authenticate()`. To expose it to configuration, call `RegisterProvider` inside `init`. Provider factories receive the specific `AccessProvider` block plus the full root configuration for contextual needs.
+
+## Error Semantics
+
+- `ErrNoCredentials`: no credentials were present or recognized by any provider.
+- `ErrInvalidCredential`: at least one provider processed the credentials but rejected them.
+- `ErrNotHandled`: instructs the manager to fall through to the next provider without affecting aggregate error reporting.
+
+Return custom errors to surface transport failures; they propagate immediately to the caller instead of being masked.
+
+## Integration with cliproxy Service
+
+`sdk/cliproxy` wires `@sdk/access` automatically when you build a CLI service via `cliproxy.NewBuilder`. Supplying a preconfigured manager allows you to extend or override the default providers:
+
+```go
+coreCfg, _ := config.LoadConfig("config.yaml")
+providers, _ := sdkaccess.BuildProviders(coreCfg)
+manager := sdkaccess.NewManager()
+manager.SetProviders(providers)
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(coreCfg).
+  WithAccessManager(manager).
+  Build()
+```
+
+The service reuses the manager for every inbound request, ensuring consistent authentication across embedded deployments and the canonical CLI binary.
+
+### Hot reloading providers
+
+When configuration changes, rebuild providers and swap them into the manager:
+
+```go
+providers, err := sdkaccess.BuildProviders(newCfg)
+if err != nil {
+    log.Errorf("reload auth providers failed: %v", err)
+    return
+}
+accessManager.SetProviders(providers)
+```
+
+This mirrors the behaviour in `cliproxy.Service.refreshAccessProviders` and `api.Server.applyAccessConfig`, enabling runtime updates without restarting the process.

+# @sdk/access 开发指引
+
+`github.com/router-for-me/CLIProxyAPI/v6/sdk/access` 包负责代理的入站访问认证。它提供一个轻量的管理器，用于按顺序链接多种凭证校验实现，让服务器在 CLI 运行时内外都能复用相同的访问控制逻辑。
+
+## 引用方式
+
+```go
+import (
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+)
+```
+
+通过 `go get github.com/router-for-me/CLIProxyAPI/v6/sdk/access` 添加依赖。
+
+## 管理器生命周期
+
+```go
+manager := sdkaccess.NewManager()
+providers, err := sdkaccess.BuildProviders(cfg)
+if err != nil {
+    return err
+}
+manager.SetProviders(providers)
+```
+
+- `NewManager` 创建空管理器。
+- `SetProviders` 替换提供者切片并做防御性拷贝。
+- `Providers` 返回适合并发读取的快照。
+- `BuildProviders` 将 `config.Config` 中的访问配置转换成可运行的提供者。当配置没有显式声明但包含顶层 `api-keys` 时，会自动挂载内建的 `config-api-key` 提供者。
+
+## 认证请求
+
+```go
+result, err := manager.Authenticate(ctx, req)
+switch {
+case err == nil:
+    // Authentication succeeded; result carries provider and principal.
+case errors.Is(err, sdkaccess.ErrNoCredentials):
+    // No recognizable credentials were supplied.
+case errors.Is(err, sdkaccess.ErrInvalidCredential):
+    // Credentials were present but rejected.
+default:
+    // Provider surfaced a transport-level failure.
+}
+```
+
+`Manager.Authenticate` 按配置顺序遍历提供者。遇到成功立即返回，`ErrNotHandled` 会继续尝试下一个；若发现 `ErrNoCredentials` 或 `ErrInvalidCredential`，会在遍历结束后汇总给调用方。
+
+若管理器本身为 `nil` 或尚未注册提供者，调用会返回 `nil, nil`，让调用方无需针对错误做额外分支即可关闭访问控制。
+
+`Result` 提供认证提供者标识、解析出的主体以及可选元数据（例如凭证来源）。
+
+## 配置结构
+
+在 `config.yaml` 的 `auth.providers` 下定义访问提供者：
+
+```yaml
+auth:
+  providers:
+    - name: inline-api
+      type: config-api-key
+      api-keys:
+        - sk-test-123
+        - sk-prod-456
+```
+
+条目映射到 `config.AccessProvider`：`name` 指定实例名，`type` 选择注册的工厂，`sdk` 可引用第三方模块，`api-keys` 提供内联凭证，`config` 用于传递特定选项。
+
+### 引入外部 SDK 提供者
+
+若要消费其它 Go 模块输出的访问提供者，可在配置里填写 `sdk` 字段并在代码中引入该包，利用其 `init` 注册过程：
+
+```yaml
+auth:
+  providers:
+    - name: partner-auth
+      type: partner-token
+      sdk: github.com/acme/xplatform/sdk/access/providers/partner
+      config:
+        region: us-west-2
+        audience: cli-proxy
+```
+
+```go
+import (
+    _ "github.com/acme/xplatform/sdk/access/providers/partner" // registers partner-token
+    sdkaccess "github.com/router-for-me/CLIProxyAPI/v6/sdk/access"
+)
+```
+
+通过空白标识符导入即可确保 `init` 调用，先于 `BuildProviders` 完成 `sdkaccess.RegisterProvider`。
+
+## 内建提供者
+
+当前 SDK 默认内置：
+
+- `config-api-key`：校验配置中的 API Key。它从 `Authorization: Bearer`、`X-Goog-Api-Key`、`X-Api-Key` 以及查询参数 `?key=` 提取凭证，不匹配时抛出 `ErrInvalidCredential`。
+
+导入第三方包即可通过 `sdkaccess.RegisterProvider` 注册更多类型。
+
+### 元数据与审计
+
+`Result.Metadata` 用于携带提供者特定的上下文信息。内建的 `config-api-key` 会记录凭证来源（`authorization`、`x-goog-api-key`、`x-api-key` 或 `query-key`）。自定义提供者同样可以填充该 Map，以便丰富日志与审计场景。
+
+## 编写自定义提供者
+
+```go
+type customProvider struct{}
+
+func (p *customProvider) Identifier() string { return "my-provider" }
+
+func (p *customProvider) Authenticate(ctx context.Context, r *http.Request) (*sdkaccess.Result, error) {
+    token := r.Header.Get("X-Custom")
+    if token == "" {
+        return nil, sdkaccess.ErrNoCredentials
+    }
+    if token != "expected" {
+        return nil, sdkaccess.ErrInvalidCredential
+    }
+    return &sdkaccess.Result{
+        Provider:  p.Identifier(),
+        Principal: "service-user",
+        Metadata:  map[string]string{"source": "x-custom"},
+    }, nil
+}
+
+func init() {
+    sdkaccess.RegisterProvider("custom", func(cfg *config.AccessProvider, root *config.Config) (sdkaccess.Provider, error) {
+        return &customProvider{}, nil
+    })
+}
+```
+
+自定义提供者需要实现 `Identifier()` 与 `Authenticate()`。在 `init` 中调用 `RegisterProvider` 暴露给配置层，工厂函数既能读取当前条目，也能访问完整根配置。
+
+## 错误语义
+
+- `ErrNoCredentials`：任何提供者都未识别到凭证。
+- `ErrInvalidCredential`：至少一个提供者处理了凭证但判定无效。
+- `ErrNotHandled`：告诉管理器跳到下一个提供者，不影响最终错误统计。
+
+自定义错误（例如网络异常）会马上冒泡返回。
+
+## 与 cliproxy 集成
+
+使用 `sdk/cliproxy` 构建服务时会自动接入 `@sdk/access`。如果需要扩展内置行为，可传入自定义管理器：
+
+```go
+coreCfg, _ := config.LoadConfig("config.yaml")
+providers, _ := sdkaccess.BuildProviders(coreCfg)
+manager := sdkaccess.NewManager()
+manager.SetProviders(providers)
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(coreCfg).
+  WithAccessManager(manager).
+  Build()
+```
+
+服务会复用该管理器处理每一个入站请求，实现与 CLI 二进制一致的访问控制体验。
+
+### 动态热更新提供者
+
+当配置发生变化时，可以重新构建提供者并替换当前列表：
+
+```go
+providers, err := sdkaccess.BuildProviders(newCfg)
+if err != nil {
+    log.Errorf("reload auth providers failed: %v", err)
+    return
+}
+accessManager.SetProviders(providers)
+```
+
+这一流程与 `cliproxy.Service.refreshAccessProviders` 和 `api.Server.applyAccessConfig` 保持一致，避免为更新访问策略而重启进程。

+# SDK Advanced: Executors & Translators
+
+This guide explains how to extend the embedded proxy with custom providers and schemas using the SDK. You will:
+- Implement a provider executor that talks to your upstream API
+- Register request/response translators for schema conversion
+- Register models so they appear in `/v1/models`
+
+The examples use Go 1.24+ and the v6 module path.
+
+## Concepts
+
+- Provider executor: a runtime component implementing `auth.ProviderExecutor` that performs outbound calls for a given provider key (e.g., `gemini`, `claude`, `codex`). Executors can also implement `RequestPreparer` to inject credentials on raw HTTP requests.
+- Translator registry: schema conversion functions routed by `sdk/translator`. The built‑in handlers translate between OpenAI/Gemini/Claude/Codex formats; you can register new ones.
+- Model registry: publishes the list of available models per client/provider to power `/v1/models` and routing hints.
+
+## 1) Implement a Provider Executor
+
+Create a type that satisfies `auth.ProviderExecutor`.
+
+```go
+package myprov
+
+import (
+  "context"
+  "net/http"
+
+  coreauth "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/auth"
+  clipexec "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/executor"
+)
+
+type Executor struct{}
+
+func (Executor) Identifier() string { return "myprov" }
+
+// Optional: mutate outbound HTTP requests with credentials
+func (Executor) PrepareRequest(req *http.Request, a *coreauth.Auth) error {
+  // Example: req.Header.Set("Authorization", "Bearer "+a.APIKey)
+  return nil
+}
+
+func (Executor) Execute(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (clipexec.Response, error) {
+  // Build HTTP request based on req.Payload (already translated into provider format)
+  // Use per‑auth transport if provided: transport := a.RoundTripper // via RoundTripperProvider
+  // Perform call and return provider JSON payload
+  return clipexec.Response{Payload: []byte(`{"ok":true}`)}, nil
+}
+
+func (Executor) ExecuteStream(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (<-chan clipexec.StreamChunk, error) {
+  ch := make(chan clipexec.StreamChunk, 1)
+  go func() { defer close(ch); ch <- clipexec.StreamChunk{Payload: []byte("data: {\"done\":true}\n\n")} }()
+  return ch, nil
+}
+
+func (Executor) Refresh(ctx context.Context, a *coreauth.Auth) (*coreauth.Auth, error) {
+  // Optionally refresh tokens and return updated auth
+  return a, nil
+}
+```
+
+Register the executor with the core manager before starting the service:
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.RegisterExecutor(myprov.Executor{})
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath(cfgPath).WithCoreAuthManager(core).Build()
+```
+
+If your auth entries use provider `"myprov"`, the manager routes requests to your executor.
+
+## 2) Register Translators
+
+The handlers accept OpenAI/Gemini/Claude/Codex inputs. To support a new provider format, register translation functions in `sdk/translator`’s default registry.
+
+Direction matters:
+- Request: register from inbound schema to provider schema
+- Response: register from provider schema back to inbound schema
+
+Example: Convert OpenAI Chat → MyProv Chat and back.
+
+```go
+package myprov
+
+import (
+  "context"
+  sdktr "github.com/router-for-me/CLIProxyAPI/v6/sdk/translator"
+)
+
+const (
+  FOpenAI = sdktr.Format("openai.chat")
+  FMyProv = sdktr.Format("myprov.chat")
+)
+
+func init() {
+  sdktr.Register(FOpenAI, FMyProv,
+    // Request transform (model, rawJSON, stream)
+    func(model string, raw []byte, stream bool) []byte { return convertOpenAIToMyProv(model, raw, stream) },
+    // Response transform (stream & non‑stream)
+    sdktr.ResponseTransform{
+      Stream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) []string {
+        return convertStreamMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+      NonStream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) string {
+        return convertMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+    },
+  )
+}
+```
+
+When the OpenAI handler receives a request that should route to `myprov`, the pipeline uses the registered transforms automatically.
+
+## 3) Register Models
+
+Expose models under `/v1/models` by registering them in the global model registry using the auth ID (client ID) and provider name.
+
+```go
+models := []*cliproxy.ModelInfo{
+  { ID: "myprov-pro-1", Object: "model", Type: "myprov", DisplayName: "MyProv Pro 1" },
+}
+cliproxy.GlobalModelRegistry().RegisterClient(authID, "myprov", models)
+```
+
+The embedded server calls this automatically for built‑in providers; for custom providers, register during startup (e.g., after loading auths) or upon auth registration hooks.
+
+## Credentials & Transports
+
+- Use `Manager.SetRoundTripperProvider` to inject per‑auth `*http.Transport` (e.g., proxy):
+  ```go
+  core.SetRoundTripperProvider(myProvider) // returns transport per auth
+  ```
+- For raw HTTP flows, implement `PrepareRequest` and/or call `Manager.InjectCredentials(req, authID)` to set headers.
+
+## Testing Tips
+
+- Enable request logging: Management API GET/PUT `/v0/management/request-log`
+- Toggle debug logs: Management API GET/PUT `/v0/management/debug`
+- Hot reload changes in `config.yaml` and `auths/` are picked up automatically by the watcher

+# SDK 高级指南：执行器与翻译器
+
+本文介绍如何使用 SDK 扩展内嵌代理：
+- 实现自定义 Provider 执行器以调用你的上游 API
+- 注册请求/响应翻译器进行协议转换
+- 注册模型以出现在 `/v1/models`
+
+示例基于 Go 1.24+ 与 v6 模块路径。
+
+## 概念
+
+- Provider 执行器：实现 `auth.ProviderExecutor` 的运行时组件，负责某个 provider key（如 `gemini`、`claude`、`codex`）的真正出站调用。若实现 `RequestPreparer` 接口，可在原始 HTTP 请求上注入凭据。
+- 翻译器注册表：由 `sdk/translator` 驱动的协议转换函数。内置了 OpenAI/Gemini/Claude/Codex 的互转；你也可以注册新的格式转换。
+- 模型注册表：对外发布可用模型列表，供 `/v1/models` 与路由参考。
+
+## 1) 实现 Provider 执行器
+
+创建类型满足 `auth.ProviderExecutor` 接口。
+
+```go
+package myprov
+
+import (
+    "context"
+    "net/http"
+
+    coreauth "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/auth"
+    clipexec "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy/executor"
+)
+
+type Executor struct{}
+
+func (Executor) Identifier() string { return "myprov" }
+
+// 可选：在原始 HTTP 请求上注入凭据
+func (Executor) PrepareRequest(req *http.Request, a *coreauth.Auth) error {
+    // 例如：req.Header.Set("Authorization", "Bearer "+a.Attributes["api_key"]) 
+    return nil
+}
+
+func (Executor) Execute(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (clipexec.Response, error) {
+    // 基于 req.Payload 构造上游请求，返回上游 JSON 负载
+    return clipexec.Response{Payload: []byte(`{"ok":true}`)}, nil
+}
+
+func (Executor) ExecuteStream(ctx context.Context, a *coreauth.Auth, req clipexec.Request, opts clipexec.Options) (<-chan clipexec.StreamChunk, error) {
+    ch := make(chan clipexec.StreamChunk, 1)
+    go func() { defer close(ch); ch <- clipexec.StreamChunk{Payload: []byte("data: {\\"done\\":true}\\n\\n")} }()
+    return ch, nil
+}
+
+func (Executor) Refresh(ctx context.Context, a *coreauth.Auth) (*coreauth.Auth, error) { return a, nil }
+```
+
+在启动服务前将执行器注册到核心管理器：
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.RegisterExecutor(myprov.Executor{})
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath(cfgPath).WithCoreAuthManager(core).Build()
+```
+
+当凭据的 `Provider` 为 `"myprov"` 时，管理器会将请求路由到你的执行器。
+
+## 2) 注册翻译器
+
+内置处理器接受 OpenAI/Gemini/Claude/Codex 的入站格式。要支持新的 provider 协议，需要在 `sdk/translator` 的默认注册表中注册转换函数。
+
+方向很重要：
+- 请求：从“入站格式”转换为“provider 格式”
+- 响应：从“provider 格式”转换回“入站格式”
+
+示例：OpenAI Chat → MyProv Chat 及其反向。
+
+```go
+package myprov
+
+import (
+  "context"
+  sdktr "github.com/router-for-me/CLIProxyAPI/v6/sdk/translator"
+)
+
+const (
+  FOpenAI = sdktr.Format("openai.chat")
+  FMyProv = sdktr.Format("myprov.chat")
+)
+
+func init() {
+  sdktr.Register(FOpenAI, FMyProv,
+    func(model string, raw []byte, stream bool) []byte { return convertOpenAIToMyProv(model, raw, stream) },
+    sdktr.ResponseTransform{
+      Stream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) []string {
+        return convertStreamMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+      NonStream: func(ctx context.Context, model string, originalReq, translatedReq, raw []byte, param *any) string {
+        return convertMyProvToOpenAI(model, originalReq, translatedReq, raw)
+      },
+    },
+  )
+}
+```
+
+当 OpenAI 处理器接到需要路由到 `myprov` 的请求时，流水线会自动应用已注册的转换。
+
+## 3) 注册模型
+
+通过全局模型注册表将模型暴露到 `/v1/models`：
+
+```go
+models := []*cliproxy.ModelInfo{
+  { ID: "myprov-pro-1", Object: "model", Type: "myprov", DisplayName: "MyProv Pro 1" },
+}
+cliproxy.GlobalModelRegistry().RegisterClient(authID, "myprov", models)
+```
+
+内置 Provider 会自动注册；自定义 Provider 建议在启动时（例如加载到 Auth 后）或在 Auth 注册钩子中调用。
+
+## 凭据与传输
+
+- 使用 `Manager.SetRoundTripperProvider` 注入按账户的 `*http.Transport`（例如代理）：
+  ```go
+  core.SetRoundTripperProvider(myProvider) // 按账户返回 transport
+  ```
+- 对于原始 HTTP 请求，若实现了 `PrepareRequest`，或通过 `Manager.InjectCredentials(req, authID)` 进行头部注入。
+
+## 测试建议
+
+- 启用请求日志：管理 API GET/PUT `/v0/management/request-log`
+- 切换调试日志：管理 API GET/PUT `/v0/management/debug`
+- 热更新：`config.yaml` 与 `auths/` 变化会自动被侦测并应用

+# CLI Proxy SDK Guide
+
+The `sdk/cliproxy` module exposes the proxy as a reusable Go library so external programs can embed the routing, authentication, hot‑reload, and translation layers without depending on the CLI binary.
+
+## Install & Import
+
+```bash
+go get github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy
+```
+
+```go
+import (
+    "context"
+    "errors"
+    "time"
+
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+    "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy"
+)
+```
+
+Note the `/v6` module path.
+
+## Minimal Embed
+
+```go
+cfg, err := config.LoadConfig("config.yaml")
+if err != nil { panic(err) }
+
+svc, err := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml"). // absolute or working-dir relative
+    Build()
+if err != nil { panic(err) }
+
+ctx, cancel := context.WithCancel(context.Background())
+defer cancel()
+
+if err := svc.Run(ctx); err != nil && !errors.Is(err, context.Canceled) {
+    panic(err)
+}
+```
+
+The service manages config/auth watching, background token refresh, and graceful shutdown. Cancel the context to stop it.
+
+## Server Options (middleware, routes, logs)
+
+The server accepts options via `WithServerOptions`:
+
+```go
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithServerOptions(
+    // Add global middleware
+    cliproxy.WithMiddleware(func(c *gin.Context) { c.Header("X-Embed", "1"); c.Next() }),
+    // Tweak gin engine early (CORS, trusted proxies, etc.)
+    cliproxy.WithEngineConfigurator(func(e *gin.Engine) { e.ForwardedByClientIP = true }),
+    // Add your own routes after defaults
+    cliproxy.WithRouterConfigurator(func(e *gin.Engine, _ *handlers.BaseAPIHandler, _ *config.Config) {
+      e.GET("/healthz", func(c *gin.Context) { c.String(200, "ok") })
+    }),
+    // Override request log writer/dir
+    cliproxy.WithRequestLoggerFactory(func(cfg *config.Config, cfgPath string) logging.RequestLogger {
+      return logging.NewFileRequestLogger(true, "logs", filepath.Dir(cfgPath))
+    }),
+  ).
+  Build()
+```
+
+These options mirror the internals used by the CLI server.
+
+## Management API (when embedded)
+
+- Management endpoints are mounted only when `remote-management.secret-key` is set in `config.yaml`.
+- Remote access additionally requires `remote-management.allow-remote: true`.
+- See MANAGEMENT_API.md for endpoints. Your embedded server exposes them under `/v0/management` on the configured port.
+
+## Using the Core Auth Manager
+
+The service uses a core `auth.Manager` for selection, execution, and auto‑refresh. When embedding, you can provide your own manager to customize transports or hooks:
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.SetRoundTripperProvider(myRTProvider) // per‑auth *http.Transport
+
+svc, _ := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml").
+    WithCoreAuthManager(core).
+    Build()
+```
+
+Implement a custom per‑auth transport:
+
+```go
+type myRTProvider struct{}
+func (myRTProvider) RoundTripperFor(a *coreauth.Auth) http.RoundTripper {
+    if a == nil || a.ProxyURL == "" { return nil }
+    u, _ := url.Parse(a.ProxyURL)
+    return &http.Transport{ Proxy: http.ProxyURL(u) }
+}
+```
+
+Programmatic execution is available on the manager:
+
+```go
+// Non‑streaming
+resp, err := core.Execute(ctx, []string{"gemini"}, req, opts)
+
+// Streaming
+chunks, err := core.ExecuteStream(ctx, []string{"gemini"}, req, opts)
+for ch := range chunks { /* ... */ }
+```
+
+Note: Built‑in provider executors are wired automatically when you run the `Service`. If you want to use `Manager` stand‑alone without the HTTP server, you must register your own executors that implement `auth.ProviderExecutor`.
+
+## Custom Client Sources
+
+Replace the default loaders if your creds live outside the local filesystem:
+
+```go
+type memoryTokenProvider struct{}
+func (p *memoryTokenProvider) Load(ctx context.Context, cfg *config.Config) (*cliproxy.TokenClientResult, error) {
+    // Populate from memory/remote store and return counts
+    return &cliproxy.TokenClientResult{}, nil
+}
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithTokenClientProvider(&memoryTokenProvider{}).
+  WithAPIKeyClientProvider(cliproxy.NewAPIKeyClientProvider()).
+  Build()
+```
+
+## Hooks
+
+Observe lifecycle without patching internals:
+
+```go
+hooks := cliproxy.Hooks{
+  OnBeforeStart: func(cfg *config.Config) { log.Infof("starting on :%d", cfg.Port) },
+  OnAfterStart:  func(s *cliproxy.Service) { log.Info("ready") },
+}
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath("config.yaml").WithHooks(hooks).Build()
+```
+
+## Shutdown
+
+`Run` defers `Shutdown`, so cancelling the parent context is enough. To stop manually:
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
+defer cancel()
+_ = svc.Shutdown(ctx)
+```
+
+## Notes
+
+- Hot reload: changes to `config.yaml` and `auths/` are picked up automatically.
+- Request logging can be toggled at runtime via the Management API.
+- Gemini Web features (`gemini-web.*`) are honored in the embedded server.

+# CLI Proxy SDK 使用指南
+
+`sdk/cliproxy` 模块将代理能力以 Go 库的形式对外暴露，方便在其它服务中内嵌路由、鉴权、热更新与翻译层，而无需依赖可执行的 CLI 程序。
+
+## 安装与导入
+
+```bash
+go get github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy
+```
+
+```go
+import (
+    "context"
+    "errors"
+    "time"
+
+    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
+    "github.com/router-for-me/CLIProxyAPI/v6/sdk/cliproxy"
+)
+```
+
+注意模块路径包含 `/v6`。
+
+## 最小可用示例
+
+```go
+cfg, err := config.LoadConfig("config.yaml")
+if err != nil { panic(err) }
+
+svc, err := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml"). // 绝对路径或工作目录相对路径
+    Build()
+if err != nil { panic(err) }
+
+ctx, cancel := context.WithCancel(context.Background())
+defer cancel()
+
+if err := svc.Run(ctx); err != nil && !errors.Is(err, context.Canceled) {
+    panic(err)
+}
+```
+
+服务内部会管理配置与认证文件的监听、后台令牌刷新与优雅关闭。取消上下文即可停止服务。
+
+## 服务器可选项（中间件、路由、日志）
+
+通过 `WithServerOptions` 自定义：
+
+```go
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithServerOptions(
+    // 追加全局中间件
+    cliproxy.WithMiddleware(func(c *gin.Context) { c.Header("X-Embed", "1"); c.Next() }),
+    // 提前调整 gin 引擎（如 CORS、trusted proxies）
+    cliproxy.WithEngineConfigurator(func(e *gin.Engine) { e.ForwardedByClientIP = true }),
+    // 在默认路由之后追加自定义路由
+    cliproxy.WithRouterConfigurator(func(e *gin.Engine, _ *handlers.BaseAPIHandler, _ *config.Config) {
+      e.GET("/healthz", func(c *gin.Context) { c.String(200, "ok") })
+    }),
+    // 覆盖请求日志的创建（启用/目录）
+    cliproxy.WithRequestLoggerFactory(func(cfg *config.Config, cfgPath string) logging.RequestLogger {
+      return logging.NewFileRequestLogger(true, "logs", filepath.Dir(cfgPath))
+    }),
+  ).
+  Build()
+```
+
+这些选项与 CLI 服务器内部用法保持一致。
+
+## 管理 API（内嵌时）
+
+- 仅当 `config.yaml` 中设置了 `remote-management.secret-key` 时才会挂载管理端点。
+- 远程访问还需要 `remote-management.allow-remote: true`。
+- 具体端点见 MANAGEMENT_API_CN.md。内嵌服务器会在配置端口下暴露 `/v0/management`。
+
+## 使用核心鉴权管理器
+
+服务内部使用核心 `auth.Manager` 负责选择、执行、自动刷新。内嵌时可自定义其传输或钩子：
+
+```go
+core := coreauth.NewManager(coreauth.NewFileStore(cfg.AuthDir), nil, nil)
+core.SetRoundTripperProvider(myRTProvider) // 按账户返回 *http.Transport
+
+svc, _ := cliproxy.NewBuilder().
+    WithConfig(cfg).
+    WithConfigPath("config.yaml").
+    WithCoreAuthManager(core).
+    Build()
+```
+
+实现每个账户的自定义传输：
+
+```go
+type myRTProvider struct{}
+func (myRTProvider) RoundTripperFor(a *coreauth.Auth) http.RoundTripper {
+    if a == nil || a.ProxyURL == "" { return nil }
+    u, _ := url.Parse(a.ProxyURL)
+    return &http.Transport{ Proxy: http.ProxyURL(u) }
+}
+```
+
+管理器提供编程式执行接口：
+
+```go
+// 非流式
+resp, err := core.Execute(ctx, []string{"gemini"}, req, opts)
+
+// 流式
+chunks, err := core.ExecuteStream(ctx, []string{"gemini"}, req, opts)
+for ch := range chunks { /* ... */ }
+```
+
+说明：运行 `Service` 时会自动注册内置的提供商执行器；若仅单独使用 `Manager` 而不启动 HTTP 服务器，则需要自行实现并注册满足 `auth.ProviderExecutor` 的执行器。
+
+## 自定义凭据来源
+
+当凭据不在本地文件系统时，替换默认加载器：
+
+```go
+type memoryTokenProvider struct{}
+func (p *memoryTokenProvider) Load(ctx context.Context, cfg *config.Config) (*cliproxy.TokenClientResult, error) {
+    // 从内存/远端加载并返回数量统计
+    return &cliproxy.TokenClientResult{}, nil
+}
+
+svc, _ := cliproxy.NewBuilder().
+  WithConfig(cfg).
+  WithConfigPath("config.yaml").
+  WithTokenClientProvider(&memoryTokenProvider{}).
+  WithAPIKeyClientProvider(cliproxy.NewAPIKeyClientProvider()).
+  Build()
+```
+
+## 启动钩子
+
+无需修改内部代码即可观察生命周期：
+
+```go
+hooks := cliproxy.Hooks{
+  OnBeforeStart: func(cfg *config.Config) { log.Infof("starting on :%d", cfg.Port) },
+  OnAfterStart:  func(s *cliproxy.Service) { log.Info("ready") },
+}
+svc, _ := cliproxy.NewBuilder().WithConfig(cfg).WithConfigPath("config.yaml").WithHooks(hooks).Build()
+```
+
+## 关闭
+
+`Run` 内部会延迟调用 `Shutdown`，因此只需取消父上下文即可。若需手动停止：
+
+```go
+ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
+defer cancel()
+_ = svc.Shutdown(ctx)
+```
+
+## 说明
+
+- 热更新：`config.yaml` 与 `auths/` 变化会被自动侦测并应用。
+- 请求日志可通过管理 API 在运行时开关。
+- `gemini-web.*` 相关配置在内嵌服务器中会被遵循。

+# SDK Watcher Integration
+
+The SDK service exposes a watcher integration that surfaces granular auth updates without forcing a full reload. This document explains the queue contract, how the service consumes updates, and how high-frequency change bursts are handled.
+
+## Update Queue Contract
+
+- `watcher.AuthUpdate` represents a single credential change. `Action` may be `add`, `modify`, or `delete`, and `ID` carries the credential identifier. For `add`/`modify` the `Auth` payload contains a fully populated clone of the credential; `delete` may omit `Auth`.
+- `WatcherWrapper.SetAuthUpdateQueue(chan<- watcher.AuthUpdate)` wires the queue produced by the SDK service into the watcher. The queue must be created before the watcher starts.
+- The service builds the queue via `ensureAuthUpdateQueue`, using a buffered channel (`capacity=256`) and a dedicated consumer goroutine (`consumeAuthUpdates`). The consumer drains bursts by looping through the backlog before reacquiring the select loop.
+
+## Watcher Behaviour
+
+- `internal/watcher/watcher.go` keeps a shadow snapshot of auth state (`currentAuths`). Each filesystem or configuration event triggers a recomputation and a diff against the previous snapshot to produce minimal `AuthUpdate` entries that mirror adds, edits, and removals.
+- Updates are coalesced per credential identifier. If multiple changes occur before dispatch (e.g., write followed by delete), only the final action is sent downstream.
+- The watcher runs an internal dispatch loop that buffers pending updates in memory and forwards them asynchronously to the queue. Producers never block on channel capacity; they just enqueue into the in-memory buffer and signal the dispatcher. Dispatch cancellation happens when the watcher stops, guaranteeing goroutines exit cleanly.
+
+## High-Frequency Change Handling
+
+- The dispatch loop and service consumer run independently, preventing filesystem watchers from blocking even when many updates arrive at once.
+- Back-pressure is absorbed in two places:
+  - The dispatch buffer (map + order slice) coalesces repeated updates for the same credential until the consumer catches up.
+  - The service channel capacity (256) combined with the consumer drain loop ensures several bursts can be processed without oscillation.
+- If the queue is saturated for an extended period, updates continue to be merged, so the latest state is eventually applied without replaying redundant intermediate states.
+
+## Usage Checklist
+
+1. Instantiate the SDK service (builder or manual construction).
+2. Call `ensureAuthUpdateQueue` before starting the watcher to allocate the shared channel.
+3. When the `WatcherWrapper` is created, call `SetAuthUpdateQueue` with the service queue, then start the watcher.
+4. Provide a reload callback that handles configuration updates; auth deltas will arrive via the queue and are applied by the service automatically through `handleAuthUpdate`.
+
+Following this flow keeps auth changes responsive while avoiding full reloads for every edit.

+# SDK Watcher集成说明
+
+本文档介绍SDK服务与文件监控器之间的增量更新队列，包括接口契约、高频变更下的处理策略以及接入步骤。
+
+## 更新队列契约
+
+- `watcher.AuthUpdate`描述单条凭据变更，`Action`可能为`add`、`modify`或`delete`，`ID`是凭据标识。对于`add`/`modify`会携带完整的`Auth`克隆，`delete`可以省略`Auth`。
+- `WatcherWrapper.SetAuthUpdateQueue(chan<- watcher.AuthUpdate)`用于将服务侧创建的队列注入watcher，必须在watcher启动前完成。
+- 服务通过`ensureAuthUpdateQueue`创建容量为256的缓冲通道，并在`consumeAuthUpdates`中使用专职goroutine消费；消费侧会主动“抽干”积压事件，降低切换开销。
+
+## Watcher行为
+
+- `internal/watcher/watcher.go`维护`currentAuths`快照，文件或配置事件触发后会重建快照并与旧快照对比，生成最小化的`AuthUpdate`列表。
+- 以凭据ID为维度对更新进行合并，同一凭据在短时间内的多次变更只会保留最新状态（例如先写后删只会下发`delete`）。
+- watcher内部运行异步分发循环：生产者只向内存缓冲追加事件并唤醒分发协程，即使通道暂时写满也不会阻塞文件事件线程。watcher停止时会取消分发循环，确保协程正常退出。
+
+## 高频变更处理
+
+- 分发循环与服务消费协程相互独立，因此即便短时间内出现大量变更也不会阻塞watcher事件处理。
+- 背压通过两级缓冲吸收：
+  - 分发缓冲（map + 顺序切片）会合并同一凭据的重复事件，直到消费者完成处理。
+  - 服务端通道的256容量加上消费侧的“抽干”逻辑，可平稳处理多个突发批次。
+- 当通道长时间处于高压状态时，缓冲仍持续合并事件，从而在消费者恢复后一次性应用最新状态，避免重复处理无意义的中间状态。
+
+## 接入步骤
+
+1. 实例化SDK Service（构建器或手工创建）。
+2. 在启动watcher之前调用`ensureAuthUpdateQueue`创建共享通道。
+3. watcher通过工厂函数创建后立刻调用`SetAuthUpdateQueue`注入通道，然后再启动watcher。
+4. Reload回调专注于配置更新；认证增量会通过队列送达，并由`handleAuthUpdate`自动应用。
+
+遵循上述流程即可在避免全量重载的同时保持凭据变更的实时性。
