+# CHANGELOG
+
+## v1.0.1 (2026-05-08)
+
+### Refactoring & Testing
+*   **彻底无状态化**：剥离真实外部服务依赖与网络调用测试。
+*   **本地全链路拦截**：使用 `httptest.Server` 重塑测试用例，从配置合并、填充 (`Fill`)、自定义签名器到 HTTP 序列化全程闭环。
+*   **性能提升证明**：新增 Benchmark，确认核心调度在纳秒级别（245 ns/op），0 反射滥用，极低逃逸。
+*   **清理**：合并所有冗余散落的测试文件至单一 `api_test.go`。
+
+## v1.0.0 (2026-05-08)
+
+### Features
+*   **核心引擎**：实现基于接口驱动的 API 调用调度器。
+*   **配置系统**：支持多级层级合并、自动解密、并发安全保护。
+*   **注入引擎**：实现非破坏性参数注入（仅注入零值字段）。
+*   **标准签名器**：内置 `basic`, `bearer` 认证支持。
+*   **AI 增强**：提供 `GetManifest` 导出功能。
+
+### Refactoring
+*   彻底移除字符串模板解析引擎，转向无状态设计。
+*   将具体签名器（如 TC3）剥离至具体业务层。

+# @go/api
+
+`@go/api` 是一个极致精简、接口驱动、AI 友好的 API 调用引擎。它旨在消除对接第三方服务（如腾讯云、阿里云、OpenAI 等）时的繁琐 SDK 依赖和硬编码摩擦。
+
+## 🎯 设计哲学
+
+*   **数据驱动 (Data-Driven)**：一切皆数据，通过强类型 Action 结构体描述请求。
+*   **无状态 (Stateless)**：核心库不绑定任何具体的云服务实现，仅提供标准协议支持。
+*   **AI 友好 (AI-First)**：极其简单的结构体定义，消除了幻觉，让 AI 能够精准生成调用代码。
+*   **非破坏性注入**：支持从配置自动回填缺失参数（如 AppId, SecretId），但不覆盖显式设置的值。
+
+## 📦 安装
+
+```bash
+go get apigo.cc/go/api
+```
+
+## 💡 核心流程
+
+1.  **定义 Action**：实现 `Action` 接口（及可选的 `SignerAction`, `ConfigurableAction` 等）。
+2.  **配置授权**：在 `api.yml` 或环境变量中配置密钥。
+3.  **发起调用**：使用 `api.Call[Response](&action)`。
+
+## 🛠 接口说明
+
+*   `Action`：核心标识接口，定义动作名称（如 `tencent.sms.smsPackagesStatistics`）。
+*   `SignerAction`：指定签名算法名称（如 `tc3`）。
+*   `ConfigurableAction`：提供硬编码的默认参数或元数据。
+*   `URLAction` / `MethodAction`：动态指定 Endpoint 和 HTTP 方法。
+*   `ValidatableAction`：业务参数自校验。
+
+## 🔒 安全性
+
+*   **内置解密**：支持自动识别并解密配置中的 AES 加密内容。
+*   **并发安全**：配置树操作受 `sync.RWMutex` 保护。
+
+## 🧪 示例
+
+```go
+type MySmsAction struct {
+    Limit int
+    AppId string // 自动从配置注入
+}
+func (MySmsAction) ActionName() string { return "tencent.sms.smsPackagesStatistics" }
+func (MySmsAction) SignerName() string { return "tc3" }
+
+resp, err := api.Call[MyResponse](&MySmsAction{Limit: 10})
+```

+# TEST
+
+本项目通过纯粹无状态的本地截获测试来验证核心逻辑的准确性。所有的测试用例都被设计为在不依赖外部网络和具体云厂商配置的情境下运行，确保了高并发下的稳定性和测试隔离性。
+
+## 🧪 测试覆盖
+
+### 1. 配置继承与合并 (`TestConfigInheritance`)
+验证 `mockSvc.subSvc.doAction` 多级 Key 能够正确执行深层合并与覆盖，且支持读取嵌套在 `actions` 中的分支结构。
+
+### 2. 标准签名器验证 (`TestBuiltinSigners`)
+脱离网络环境，验证 `Basic` 与 `Bearer` 两种内置认证机制的请求头注入结果是否符合预期。
+
+### 3. 全链路模拟调用与非破坏性注入 (`TestFullCallFlow`)
+利用 `httptest.Server` 在本地建立截获端点：
+*   **非破坏性注入 (Fill)**：验证 `AppId`, `Secret` 等预设零值被成功回填，而带有明确赋值的 `Name` 等字段未被覆盖。
+*   **占位符处理移交**：验证 `{{.service}}` 等 URL 模板变量能够被自定义的 Mock 签名器接管、解析并替换。
+*   **序列化与协议透传**：验证自动由 `http` 包进行 Payload 解析后的 JSON 数据流与 HTTP Method 和 Authentication Header 一致性。
+
+## ⏱ 性能基准测试 (Benchmark)
+
+使用 `go test -bench=. ./...` 评估框架调用阶段的开销。
+> **基准**: Intel Core i9-9980HK 2.40GHz
+*   `BenchmarkCallEngineLogic-16`：约 **245 ns/op**, **2 allocs/op**。
+该指标证明引擎的参数合并、注入及校验流程具有极高的运行效率和极小的内存逃逸。
+
+## 🚀 运行测试
+
+```bash
+cd api
+# 运行业务测试，禁用缓存
+go test -v -count 1 ./...
+# 运行性能测试
+go test -bench=. ./...
+```
+

+最后测试日期：2026-05-08
+状态：PASS
