-# 「配對」用詞一致化 — 完整 mapping 表（frontend 照表落地）
-
-> 狀態：待 frontend 落地 · 產出：Design Agent · 語言：zh-TW
-> 目標檔：`visionA-frontend/src/lib/i18n/dictionaries/zh-Hant.ts`（zh）+ `en.ts`（en）
-> **本文件只出 mapping，不改任何 code / i18n 檔。frontend 照表逐 key 替換，不需自己判斷。**
-
----
-
-## 0. 為什麼要改（一句話）
-
-「配對裝置」讓使用者誤以為在配對 KL520/KL720 **晶片**，但實際配對的是**使用者電腦上的 local-agent**（建立雲端帳號 ↔ 這台電腦的信任連結；之後這台電腦上所有 USB 裝置都能從雲端操作）。所以把主詞從「裝置」換成「電腦」。
-
-## 1. 心智模型（frontend 理解用，務必記住）
-
-系統裡有**兩層不同的連結**，過去都叫「連接/連線」，這次改詞就是要讓兩層在同一畫面不打架：
-
-| 層 | 原本叫什麼 | 這次改成 | 語意 | 頻率 | 對象 |
-|----|-----------|---------|------|------|------|
-| **信任連結** | 配對 / pairing | **連接這台電腦 / Connect this computer** | 建立「雲端帳號 ↔ 這台電腦」的信任，一次性 | 一次 | 電腦（host / local-agent） |
-| **驅動連線** | 連線 / connect（`devices.connect.*`） | **不動**（維持「連線 / 斷線」） | 每次要用某顆 USB 晶片時開啟 driver 連線 | 每次使用 | 裝置（USB 晶片） |
-
-**一句話**：**「連接電腦」是把整台電腦接進你的雲端帳號（原 pairing）；「連線裝置」是開始使用電腦上的某顆晶片（原 device connect，不動）。**
-
-## 2. 避撞規則（frontend 落地時的鐵則）
-
-1. `common.connect="連接"`、`common.disconnect="中斷連線"`、`devices.connect.*`（連線/斷線/連線中）**全部保持不動**。
-2. **pairing 相關新詞一律帶主詞「電腦 / 這台電腦」**，不可出現裸「連接」。靠主詞讓使用者秒分辨兩層：
-   - ✅「連接這台電腦」「已連接的電腦」「重新連接電腦」
-   - ❌「連接」「已連接」（會跟裝置層 `devices.filter.onlineRegistered="已連接"` 撞）
-3. 英文同理：pairing 用 **connect (this) computer / connected computer**；裝置層維持既有 connect/disconnect 用於 device driver。英文 `Connected!`（pairing.step3.success）維持不變，因為那是「電腦已接上雲端」的成功提示，語境清楚。
-
-## 3. 成套用詞決定（正向 / 反向 / 名詞 / 欄位）
-
-| 類別 | 舊詞 | 新詞（zh） | 新詞（en） | 理由 |
-|------|------|-----------|-----------|------|
-| **正向動作** | 配對 / Pair | 連接這台電腦 / **Connect this computer**（按鈕短版「連接電腦 / Connect computer」） | 主詞換成電腦、消除晶片誤解；長句重寫成「連接你的電腦，就能從雲端使用裝置」 |
-| **反向動作（unpair）** | 解除配對 / unpair | **中斷這台電腦的連接 / 解除電腦連接**（動作按鈕沿用既有「移除裝置」不動，內文用「解除電腦連接」） | Disconnect this computer / unlink | unpair 語意=「移除裝置紀錄 + 撤銷存取」；改詞**不改語意**。用「解除…連接」對應正向「連接」，成套。註：現有 `devices.remove.action="移除裝置"` 是刪 device 紀錄的動作，**保持不動**；只有描述 pairing 關係的句子才改。 |
-| **名詞（Token）** | Pairing Token | **連接碼**（口語處）/ **連接 Token**（技術處） | **Pairing token → connection token**；CLI 參數 `--relay-token` **不動** | 見 §4「保留 pairing 原文」判定：token 名詞面向使用者改「連接碼」較白話；`--relay-token` 是實際 CLI flag，屬 code identifier，**絕不改**。 |
-| **欄位（pairedAt）** | 配對時間 / Paired at | **連接時間 / Connected at** | i18n label 可改；底層欄位名 `pairedAt`（API/DB）**不改**，只改顯示字。 |
-| **重新配對（re-pair）** | 重新配對 / re-pair | **重新連接電腦 / re-connect (the computer)** | 成套。凡「請在 local agent 重新配對一次」→「請在 local agent 重新連接一次」。 |
-
-### 3.1 判定「保留 pairing 原文」的技術術語（不改）
-
-| 保留項 | 出現位置 | 為何不改 |
-|--------|---------|---------|
-| `--relay-token` | `pairing.cli.description` | 實際 CLI flag、code identifier，改了指令會壞。 |
-| i18n **key 名**（`pairing.*`、`pairedAt`、`dashboard.pairDevice` 等） | 全部 key | 只改 value，不改 key（改 key 要動用到處引用的元件，超出本次範圍且無使用者可見效益）。 |
-| API/DB 欄位 `pairedAt`、後端 `pairing` endpoint、路由 `/devices/pair` | 非 i18n | 使用者拍板「不改路由」；欄位名屬後端契約，本次只改前端顯示文案。 |

-## 4. 完整 mapping 表（涵蓋 zh 55 處 + en 57 處）
-
-> 說明：一個 i18n key = 一列，同時給 zh/en 舊→新。frontend 逐列替換 value 即可。
-> 「備註」欄標注句子有無重寫、避撞注意。行號為撰文時快照（zh-Hant.ts / en.ts），實際以 key 為準。
-
-### 4.1 Dashboard
-
-| i18n key | 舊 zh | 新 zh | 舊 en | 新 en | 備註 |
-|----------|-------|-------|-------|-------|------|

-| `dashboard.noActivity` | 還沒有任何活動。配對裝置、上傳模型或跑一次推論後就會出現。 | 還沒有任何活動。連接電腦、上傳模型或跑一次推論後就會出現。 | Nothing here yet. Activity appears after pairing, uploads, or inference runs. | Nothing here yet. Activity appears after connecting a computer, uploads, or inference runs. | pairing→connecting a computer |
-| `dashboard.pairDevice` | 配對裝置 | 連接電腦 | Pair device | Connect computer | 按鈕短版 |
-| `dashboard.empty.description` | 配對你的第一台 Kneron 裝置，開始雲端推論之旅 | 連接你的電腦，開始從雲端使用 Kneron 裝置 | Pair your first Kneron device to start running inference from anywhere. | Connect your computer to start using Kneron devices from anywhere. | 句子重寫 |
-| `dashboard.empty.action` | 配對裝置 | 連接電腦 | Pair a device | Connect computer | 按鈕短版 |
-
-### 4.2 Devices（列表 / 空狀態 / 詳情）
-
-| i18n key | 舊 zh | 新 zh | 舊 en | 新 en | 備註 |
-|----------|-------|-------|-------|-------|------|
-| `devices.addMore` | 配對新裝置 | 連接新電腦 | Pair a new device | Connect a new computer | |
-| `devices.pairAction` | 配對新裝置 | 連接新電腦 | Pair a new device | Connect a new computer | 與上同值 |
-| `devices.empty.title` | 還沒有配對的裝置 | 還沒有連接任何電腦 | No devices paired yet | No computers connected yet | |
-| `devices.empty.description` | 在你的電腦上執行 local agent 並完成配對，就能從任何地方存取你的 Kneron 裝置 | 在你的電腦上執行 local agent 並完成連接，就能從任何地方存取你的 Kneron 裝置 | Run local agent on your computer and complete pairing to access your Kneron devices from anywhere. | Run local agent on your computer and complete the connection to access your Kneron devices from anywhere. | 完成配對→完成連接 |

-
-### 4.3 Devices：序號 missingHint（re-pair）
-
-| i18n key | 舊 zh | 新 zh | 舊 en | 新 en | 備註 |
-|----------|-------|-------|-------|-------|------|
-| `devices.serial.missingHint` | 此裝置尚未回報序號，無法執行推論相關操作。請在 local agent 重新配對一次，序號回報後即可使用。 | 此裝置尚未回報序號，無法執行推論相關操作。請在 local agent 重新連接一次，序號回報後即可使用。 | This device hasn't reported its serial number, so inference-related actions are unavailable. Re-pair it once from local agent to report the serial. | This device hasn't reported its serial number, so inference-related actions are unavailable. Re-connect once from local agent to report the serial. | re-pair→re-connect |
-
-### 4.4 Devices：移除裝置（unpair 語意，reverse action）
-
-| i18n key | 舊 zh | 新 zh | 舊 en | 新 en | 備註 |
-|----------|-------|-------|-------|-------|------|
-| `devices.remove.confirm.description` | 這會解除「{name}」與你帳號的配對並撤銷其存取權限。若要再次使用，需從 local agent 重新配對。此操作無法復原。 | 這會解除「{name}」與你帳號的連接並撤銷其存取權限。若要再次使用，需從 local agent 重新連接。此操作無法復原。 | This unpairs "{name}" from your account and revokes its access. To use it again, you'll need to pair it from local agent. This cannot be undone. | This disconnects "{name}" from your account and revokes its access. To use it again, you'll need to connect it from local agent. This cannot be undone. | **反向成套**：unpairs→disconnects；「解除…配對」→「解除…連接」。unpair 語意（刪紀錄+撤存取）不變。`devices.remove.action="移除裝置"` 按鈕**不動**。 |
-
-> 註：`devices.remove.action / removing / confirm.title / confirm.action / toast.success / error.*`（移除/移除中/確定要移除此裝置/移除/已移除裝置…）**全部不含「配對」字樣，保持不動**。這些是「移除 device 紀錄」的動作詞，與 pairing 改詞無關。

Re-connect once from local agent; these actions unlock after the serial is reported. | re-pair→re-connect |

-## 5. 明確「不動」清單（frontend 別誤改）
-
-以下 key 含「連接 / 連線 / connect」但屬**裝置驅動層或網路層**，與 pairing 無關，**一律不改**：
-
-- `common.connect="連接"`、`common.disconnect="中斷連線"`
-- `devices.connect.*` 全部（action 連線 / connecting 連線中 / disconnect 斷線 / driverStatusLabel 連線狀態 / toast.* …）
-- `devices.filter.onlineRegistered="已連接"`、`devices.filter.onlineUnregistered`、`devices.filter.offline`
-- `devices.status.connecting/connected/disconnected`、`devices.detail.port="連接埠"`
-- `devices.rescan.offlineHint`（「請先連接 local agent…」屬 agent 在線語意）
-- `tunnel.status.*`、`remote.status.*`、各處「連線失敗 / 網路連線」等網路語意字串
-- `devices.remove.action/removing/confirm.title/confirm.action/toast/error.*`（移除 device 紀錄動作、非 pairing 詞）
-
----
-
-## 6. 落地後驗證（frontend / Design QA 自檢）
-
-1. **同畫面不打架**：Devices 列表頁同時出現「連接新電腦」（pairing 按鈕）與裝置卡片上「連線 / 斷線」（device driver）時，主詞清楚不混淆。
-2. **grep 檢查**：改完後 `pairing.*` value 與 dashboard/devices/workspace 的 pairing 文案不再出現裸「配對」；en 不再出現 `Pair`/`pairing`/`unpair`（除 `--relay-token`、i18n key 名、`pairedAt` 欄位名外）。
-3. **避撞檢查**：pairing 新詞不得出現裸「連接/已連接」（無主詞），必帶「電腦」。
-4. **語意不變檢查**：`devices.remove.confirm.description`（unpair）改詞後仍表達「移除裝置紀錄 + 撤銷存取 + 不可復原」。

- * DeviceRescanButton — 重新掃描 USB 裝置按鈕
- *
- * 動機：
- *   使用者插入新的 USB 裝置後，雲端網頁抓不到（需重啟 local agent 才會 rescan）。
- *   後端 rescan 管線全部現成：`POST /api/devices/scan`（雲端 proxy 轉發 local agent
- *   的 ScanDevices → Rescan，重新偵測 USB 含新插入 / 拔除）。本按鈕補上前端入口：
- *   點按鈕 → rescanDevices()（打 scan → 成功後 fetchDevices refresh）→ 新裝置就出現。
- *
- * 行為：
- *   - loading：掃描中 disable + spinner + 文案「掃描中…」。
- *   - 成功：toast「已重新掃描」。
- *   - 失敗：toast 友善錯誤；tunnel 離線（TUNNEL_DISCONNECTED）給明確提示。
- *
- * 離線 gate：
- *   scan 是 tunnel proxy 操作，無 online agent 時後端必回 502 TUNNEL_DISCONNECTED。
- *   為避免使用者點了才失敗，這裡在「沒有任何 online 裝置」時直接 disable 按鈕，
- *   並以 title / aria 提示原因（比照 workspace 對 tunnel 離線的處理精神）。
