-    "github.com/router-for-me/CLIProxyAPI/v6/internal/config"
 )
 ```
 
 Add the module with `go get github.com/router-for-me/CLIProxyAPI/v6/sdk/access`.
 
+## Provider Registry
+
+Providers are registered globally and then attached to a `Manager` as a snapshot:
+
+- `RegisterProvider(type, provider)` installs a pre-initialized provider instance.
+- Registration order is preserved the first time each `type` is seen.
+- `RegisteredProviders()` returns the providers in that order.
+
 ## Manager Lifecycle
 
 ```go
 manager := sdkaccess.NewManager()
-providers, err := sdkaccess.BuildProviders(cfg)
-if err != nil {
-    return err
-}
-manager.SetProviders(providers)
+manager.SetProviders(sdkaccess.RegisteredProviders())
 ```
 
 * `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.
+
+If the manager itself is `nil` or no providers are configured, the call returns `nil, nil`, allowing callers to treat access control as disabled.
 
 ## Authenticating Requests
 
 ```go
-result, err := manager.Authenticate(ctx, req)
+result, authErr := manager.Authenticate(ctx, req)
 switch {
-case err == nil:
+case authErr == nil:
     // Authentication succeeded; result describes the provider and principal.
-case errors.Is(err, sdkaccess.ErrNoCredentials):
+case sdkaccess.IsAuthErrorCode(authErr, sdkaccess.AuthErrorCodeNoCredentials):

-case errors.Is(err, sdkaccess.ErrInvalidCredential):
+case sdkaccess.IsAuthErrorCode(authErr, sdkaccess.AuthErrorCodeInvalidCredential):
     // Supplied credentials were present but rejected.
 default:
-    // Transport-level failure was returned by a provider.
+    // Internal/transport 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.

+`Manager.Authenticate` walks the configured providers in order. It returns on the first success, skips providers that return `AuthErrorCodeNotHandled`, and aggregates `AuthErrorCodeNoCredentials` / `AuthErrorCodeInvalidCredential` for a final result.
 
 Each `Result` includes the provider identifier, the resolved principal, and optional metadata (for example, which header carried the credential).
 
-## Configuration Layout
+## Built-in `config-api-key` Provider
 
-The manager expects access providers under the `auth.providers` key inside `config.yaml`:
+The proxy includes one built-in access provider:
+
+- `config-api-key`: Validates API keys declared under top-level `api-keys`.
+  - Credential sources: `Authorization: Bearer`, `X-Goog-Api-Key`, `X-Api-Key`, `?key=`, `?auth_token=`
+  - Metadata: `Result.Metadata["source"]` is set to the matched source label.
+
+In the CLI server and `sdk/cliproxy`, this provider is registered automatically based on the loaded configuration.
 
 ```yaml
-auth:
-  providers:
-    - name: inline-api
-      type: config-api-key
-      api-keys:
-        - sk-test-123
-        - sk-prod-456
+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.

-- `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.

 ## 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。
+- `NewNoCredentialsError()`（`AuthErrorCodeNoCredentials`）：未提供或未识别到凭证。（HTTP 401）
+- `NewInvalidCredentialError()`（`AuthErrorCodeInvalidCredential`）：凭证存在但校验失败。（HTTP 401）
+- `NewNotHandledError()`（`AuthErrorCodeNotHandled`）：告诉管理器跳到下一个 provider。
+- `NewInternalAuthError(message, cause)`（`AuthErrorCodeInternal`）：网络/系统错误。（HTTP 500）

+使用 `sdk/cliproxy` 构建服务时会自动接入 `@sdk/access`。如果希望在宿主进程里复用同一个 `Manager` 实例，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)
+accessManager := sdkaccess.NewManager()

   WithConfig(coreCfg).
-  WithAccessManager(manager).
+  WithConfigPath("config.yaml").
+  WithRequestAccessManager(accessManager).
   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。
+请在调用 `Build()` 之前完成自定义 provider 的注册（通常通过空白导入触发 `init`），以确保它们被包含在全局 registry 的快照中。
 
 ### 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：
+当配置发生变化时，刷新依赖配置的 provider，然后重置 manager 的 provider 链：

-providers, err := sdkaccess.BuildProviders(newCfg)
-if err != nil {

+configaccess.Register(&newCfg.SDKConfig)
+accessManager.SetProviders(sdkaccess.RegisteredProviders())

-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。
