## 實作狀態（MVP）
|
||||
|

目前已實作**個人存取權杖（PAT）模式**的最小可用版本，涵蓋 P2 指令：
|
||||
|

| 指令 | 狀態 |

|------|------|

|
||||
| `bear token` | ✅ 已實作（印出 PAT；`--refresh` 在 PAT 模式下無作用） |
|
||||
| `bear logout` | ✅ 已實作（清除本機憑證；PAT 需至網頁撤銷） |
|
||||
| `bear status` | ✅ 已實作（純本機判定） |
|
||||
| `bear apps` | ⏳ P3 暫緩 |
|
||||
|
||||
### 建置與執行
|
||||
|
||||
```bash
|
||||
mix deps.get # 安裝依賴（Req、Jason）
|
||||
mix test # 跑單元測試

mix escript.build # 產生單檔可執行 `bear`

./bear --help
|
||||
./bear login --token <PAT> --issuer https://alterminal.com
|

```
|
||||
|

### 3.1 `bear login`
|
||||
|
||||
啟動 Device Flow 登入，取得並保存 Token。
|
||||
登入並保存 Token。目前有兩種模式：
|
||||
|
||||
- **PAT 模式（現行）**：`bear login --token <PAT>`，以個人存取權杖驗證 `GET /userinfo` 後保存 token，全程免瀏覽器。
|
||||
- **Device Flow（待 P1）**：`bear login`，啟動 Device Authorization Grant（RFC 8628），需伺服器端 P1 完成。
|
||||
|
||||
```
|
||||
bear login [--scope "openid profile email"] [--client-id ID]
|
||||
bear login [--token <PAT>] [--scope "openid profile email"] [--client-id ID]

|
||||
**PAT 模式行為**：
|
||||
|
||||
1. 向 `{issuer}/userinfo` 送 `Authorization: Bearer <PAT>` 驗證 token。
|
||||
2. 成功 → 寫入憑證檔（0600），印出 `已登入：<email>`；失敗（401）→ 印出錯誤，退出碼 `1`；網路錯誤 → 退出碼 `6`。
|
||||
|
||||
**Device Flow 行為**：
|
||||
|
||||
1. 讀取設定 → 向 `{issuer}/.well-known/openid-configuration` 取 `device_authorization_endpoint`（**動態發現，不寫死網址**）。
|
||||
2. `POST /device_authorization`（`client_id` + `scope`）。
