離線包齊不齊，要真正跑任務

訂判斷及所需輸入

題內任務載頁面及 JS，再讀種子2、3，顯示5。只有頁面及程序會出 no-seed，更正須連種子也有。瀏覽器真正設離線，路由只從明列記憶體集合供應。

已填本地測試工作表
情況	輸入 JSON
原例測試	{"cacheSeed":true,"values":[2,3]}

真正瀏覽器資產請求在本地截住；未知路由中止，不向外續送。此有限發放測試不是通用 service worker，也未證明整套業務系統都可離線。

錯誤及所需輸出
路徑	輸出 JSON
錯誤路徑	{"offline":true,"text":"no-seed","missing":["/seed.json"],"externalTransport":0}
所需路徑	{"offline":true,"text":"5","missing":[],"externalTransport":0}

按邊界依據作判斷

欠種子仍失敗；有空種子顯示0；集合清單未知便停。

列任務所需資產
跑獨立離線任務
核輸出及欠路由

不能用一次結果推整體離線功能。

可編輯邊界輸入及結果
條件	輸入 JSON	預期輸出 JSON
包確實欠資料種子	{"cacheSeed":false,"values":[2,3]}	{"offline":true,"text":"no-seed","missing":["/seed.json"],"externalTransport":0}
有明確空種子	{"cacheSeed":true,"values":[]}	{"offline":true,"text":"0","missing":[],"externalTransport":0}
本地集合清單未知	{"cacheSeed":null,"values":[2,3]}	{"held":true}

原例程序載到了，任務就完成嗎？

查看參考答案

不是，也需要種子。更正獨立執行顯示5，沒有欠路由。
