+# People 頁面設計文件
+
+## 1. 分層架構
+
+| 層級 | 負責 |
+|---|---|
+| **Rust (Backend)** | API 代理、檔案系統存取、API key 管理 |
+| **Vue (Frontend)** | UI 渲染、狀態管理、使用者交互 |
+
+---
+
+## 2. Core API 端點（已實測驗證）
+
+詳見 `CORE_API_REFERENCE.md`。以下摘要 People 頁面使用的端點：
+
+| 功能 | Method | 端點 | Response Key | 備註 |
+|---|---|---|---|---|
+| 列出人物 | GET | `/api/v1/identities` | `identities` | 含 metadata.starred |
+| 人物詳情 | GET | `/api/v1/identity/{uuid}` | 頂層 | 含 tmdb_profile 路徑 |
+| 搜尋人物 | GET | `/api/v1/identities/search?q=` | `results` | 欄位不同於 list |
+| 大頭照 | — | 本地檔案讀取 | — | 非 Core API |
+| 人臉列表 | GET | `/api/v1/identity/{uuid}/faces` | `data` | **不是** `faces` |
+| 追蹤列表 | GET | `/api/v1/identity/{uuid}/traces` | `traces` | |
+| 改名 | PATCH | `/api/v1/identity/{uuid}` | 頂層 | Body: `{"name": "..."}` |
+| 刪除 | DELETE | `/api/v1/identity/{uuid}` | — | 204/404 |
+| 建立 | POST | `/api/v1/identity` | — | 需要 face_json_path |
+| 合併 | POST | `/api/v1/identity/{uuid}/mergeinto` | — | Body: `{"into_uuid": "..."}` |
+| 綁定 | POST | `/api/v1/identity/{uuid}/bind` | — | Body: `{"face_id": "string", "file_uuid": "..."}` |
+| 解綁 | POST | `/api/v1/identity/{uuid}/unbind` | — | Body: 同上 |
+| 候選人臉 | GET | `/api/v1/faces/candidates` | `candidates` | |
+| 縮圖 | GET | `/api/v1/file/{uuid}/thumbnail` | Binary | |
+| 影片 | GET | `/api/v1/file/{uuid}/video` | Binary | |
+
+---
+
+## 3. Rust Structs 定義
+
+```rust
+struct PersonInfo {
+    identity_uuid: String,
+    name: String,
+    starred: bool,  // 從 metadata.starred 提取
+}
+
+struct FaceInfo {
+    id: i64,
+    file_uuid: String,
+    frame_number: i64,
+    timestamp_secs: f64,
+    face_id: Option<String>,
+    confidence: f64,
+}
+
+struct TraceInfo {
+    trace_id: i64,
+    file_uuid: String,
+    frame_count: i64,
+    first_sec: f64,
+    last_sec: f64,
+    avg_confidence: f64,
+}
+
+struct FaceCandidate {
+    id: i64,
+    face_id: Option<String>,
+    file_uuid: String,
+    frame_number: i64,
+    confidence: f64,
+}
+
+struct SearchIdentityResult {
+    identity_id: i64,
+    name: String,
+    source: String,
+    tmdb_id: Option<i64>,
+    file_uuid: Option<String>,
+    start_time: f64,
+    end_time: f64,
+    text_content: Option<String>,
+}
+```

+
+## 4. Rust Commands 清單
+
+### 4.1 現有（需修改）
+| Command | 修改內容 |
+|---|---|
+| `get_people` | PersonInfo 加 `starred: bool`，解析 metadata.starred |
+| `get_faces` | 解析 `data` key 而非 `faces`，FaceInfo 加 timestamp_secs |
+| `get_video_stream` | **重構**：寫入 temp file → 回傳 `file://` URL |
+
+### 4.2 現有（不變）
+| Command | 行為 |
+|---|---|
+| `get_traces` | `GET /identity/{uuid}/traces` |
+| `get_identity_profile` | 讀本地 profile.jpg → base64 |
+| `update_identity_name` | `PATCH /identity/{uuid}` |
+| `delete_identity` | `DELETE /identity/{uuid}` |
+| `get_thumbnail` | 抓縮圖 → base64 |
+
+### 4.3 新增
+| Command | Core API | Body/Params | 回傳 |
+|---|---|---|---|
+| `search_identities` | `GET /identities/search?q=...` | `query: String, limit: usize` | `Vec<SearchIdentityResult>` |
+| `merge_identities` | `POST /identity/{uuid}/mergeinto` | `uuid: String, into_uuid: String` | `()` |
+| `bind_face` | `POST /identity/{uuid}/bind` | `uuid, face_id: String, file_uuid: String` | `()` |
+| `unbind_face` | `POST /identity/{uuid}/unbind` | `uuid, face_id: String, file_uuid: String` | `()` |
+| `get_face_candidates` | `GET /faces/candidates` | `page: usize, per_page: usize` | `Vec<FaceCandidate>` |
+
+**注意：create_identity 需要 face_json_path，不在 People 頁面直接使用。**

+## 5. Vue 前端元件樹
+
+```
+PeopleView.vue
+├── Toolbar
+│   ├── h1 "People"
+│   ├── 搜尋框 → debounce 300ms → invoke('search_identities')
+│   └── 建立按鈕（暫留，create 需要 face_json_path）
+│
+├── PeopleGrid
+│   └── PersonCard × N (v-for filteredPeople)
+│       ├── 大頭照 → invoke('get_identity_profile') cache
+│       ├── 名稱
+│       ├── ⭐ 星號 (starred)
+│       └── @click → selectPerson()
+│
+├── DetailModal
+│   ├── Header: 大頭照 + 可編輯名稱 + UUID
+│   ├── FacesTab (橫向捲軸)
+│   │   └── face × N → confidence %
+│   ├── TracesTab (縱向列表)
+│   │   └── trace × N → 時間 + 信心% → @click → VideoPlayer
+│   └── ActionsTab
+│       ├── Delete → confirm + invoke('delete_identity')
+│       ├── Merge → 搜尋目標 + invoke('merge_identities')
+│       ├── Bind Face → 從 Candidates 選取 → invoke('bind_face')
+│       └── Unbind Face → invoke('unbind_face')
+│
+├── CandidatesModal
+│   └── FaceCandidate × N → @click → bind_face()
+│
+└── VideoPlayer (共用元件)
+    └── <video :src="videoSrc"> (file:// URL from temp file)

+
+## 8. 實作順序
+
+1. **Phase 1**: 修改 `PersonInfo` + `FaceInfo` struct + 重構 `get_video_stream` (temp file)
+2. **Phase 2**: 新增 `search_identities` + `get_face_candidates`
+3. **Phase 3**: 新增 `merge_identities` + `bind_face` + `unbind_face`
+4. **Phase 4**: Vue PeopleView 完整 UI（grid + modal + tabs + actions + 搜尋 + 合併 + 綁定）
+5. **Phase 5**: 更新 AGENTS.md + 提交
