+# SI-M1 Face SDK License Request
+
+This public DLL-only package requires a project-specific license file for real serial-port runtime usage. Mock mode does not require a license.
+
+## License File Path
+
+Place the license file at:
+
+```text
+Assets/StreamingAssets/si-m1_face.dat
+```
+
+The SDK reads this file through `Application.streamingAssetsPath`.
+
+## Required Unity Binding Parameters
+
+Provide these values from the Unity project that will run the SDK:
+
+| Field | Unity Source |
+|---|---|
+| `identifier` | `Application.identifier` |
+| `companyName` | `Application.companyName` |
+| `productName` | `Application.productName` |
+| `version` | `Application.version` |
+| `unityVersion` | `Application.unityVersion` |
+
+If any of these values changes, the existing license becomes invalid and a new license is required.
+
+## Parameter Probe
+
+Add this temporary script to the customer project and copy the Console output when requesting a license:
+
+```csharp
+using UnityEngine;
+
+public sealed class FaceLicenseParameterPrinter : MonoBehaviour
+{
+    private void Awake()
+    {
+        Debug.Log("identifier=" + Application.identifier);
+        Debug.Log("companyName=" + Application.companyName);
+        Debug.Log("productName=" + Application.productName);
+        Debug.Log("version=" + Application.version);
+        Debug.Log("unityVersion=" + Application.unityVersion);
+    }
+}
+```
+
+## Request Information
+
+Provide:
+
+| Item | Example |
+|---|---|
+| Customer name | `customer-a` |
+| Project name | `Face App` |
+| Unity binding parameters | See above |
+| License start time | `2026-08-10T00:00:00+08:00` |
+| License expiry time | `2027-08-10T00:00:00+08:00` |
+| Licensed features | `SerialRuntime,Basic,Verify,Enroll` |
+
+License times use Beijing time and must use `yyyy-MM-ddTHH:mm:ss+08:00`.
+
+## Common Failures
+
+| Symptom | Cause |
+|---|---|
+| License file missing | `si-m1_face.dat` is not under `Assets/StreamingAssets` |
+| Binding mismatch | One of the Unity binding parameters changed |
+| Expired | Current Beijing time is after `expireAt` |
+| Not yet valid | Current Beijing time is before `issuedAt` |
+| Feature denied | The license does not include the requested SDK feature |
+| Invalid signature | The file was modified or does not match this SDK build |

+# SI-M1 Face SDK 授权申请
+
+DLL-only 公开包在真实串口运行时需要项目专用授权文件。Mock 模式不需要授权。
+
+## 授权文件路径
+
+授权文件必须放在客户 Unity 项目中：
+
+```text
+Assets/StreamingAssets/si-m1_face.dat
+```
+
+SDK 会通过 `Application.streamingAssetsPath` 读取该文件。
+
+## 需要提供的 Unity 绑定参数
+
+申请授权时需要提供运行 SDK 的 Unity 项目参数：
+
+| 字段 | Unity 读取来源 |
+|---|---|
+| `identifier` | `Application.identifier` |
+| `companyName` | `Application.companyName` |
+| `productName` | `Application.productName` |
+| `version` | `Application.version` |
+| `unityVersion` | `Application.unityVersion` |
+
+这些值任意变化后，已有授权会失效，需要重新申请授权。
+
+## 参数打印脚本
+
+客户可以在项目中临时添加以下脚本，并把 Console 输出发给授权人员：
+
+```csharp
+using UnityEngine;
+
+public sealed class FaceLicenseParameterPrinter : MonoBehaviour
+{
+    private void Awake()
+    {
+        Debug.Log("identifier=" + Application.identifier);
+        Debug.Log("companyName=" + Application.companyName);
+        Debug.Log("productName=" + Application.productName);
+        Debug.Log("version=" + Application.version);
+        Debug.Log("unityVersion=" + Application.unityVersion);
+    }
+}
+```
+
+## 授权申请信息
+
+建议提供：
+
+| 项 | 示例 |
+|---|---|
+| 客户名称 | `customer-a` |
+| 项目名称 | `Face App` |
+| Unity 绑定参数 | 见上文 |
+| 授权开始时间 | `2026-08-10T00:00:00+08:00` |
+| 授权过期时间 | `2027-08-10T00:00:00+08:00` |
+| 授权功能 | `SerialRuntime,Basic,Verify,Enroll` |
+
+授权时间使用北京时间，格式必须为 `yyyy-MM-ddTHH:mm:ss+08:00`。
+
+## 常见失败原因
+
+| 现象 | 原因 |
+|---|---|
+| 授权文件不存在 | `si-m1_face.dat` 没有放在 `Assets/StreamingAssets` 下 |
+| 授权绑定不匹配 | Unity 绑定参数发生变化 |
+| 授权已过期 | 当前北京时间晚于 `expireAt` |
+| 授权尚未生效 | 当前北京时间早于 `issuedAt` |
+| 功能未授权 | 授权中不包含当前调用的 SDK 功能 |
+| 签名无效 | 授权文件被修改，或与当前 SDK 构建不匹配 |
