fix(portal): 讀不到就說讀不到——總圖不再把「讀不到」畫成「你沒有」(Arcrun#100)
leo 2026-08-12 打開總圖看到:「0 個實體 · 0 條關聯/知識庫還沒有任何關聯—— 上傳文件後 AI 會自動織網」。**而他庫裡有 1854 條三元組。** 那句話會叫他去做一件不需要做的事。 三個獨立的洞疊起來才變成那句謊: ① console-dashboard.ts 打 kbdb-graph-plugin 沒帶認證(同段落打 kbdb 的兩支都有帶) ② 那顆 worker 不在更新的部署清單裡 ⇒ token 一換它就落單 ③ **畫面把 null 畫成 0**——後端已經誠實回 null 了,是前端把它變成謊話 為什麼一直沒被發現:graph plugin 原本身上沒有 token ⇒ 門開著 ⇒ 沒帶也進得去。 2026-08-12 輪替後它有了 token,門關上,401 才浮出來。 📍 repo:matrix/arcrun(cypher-executor/src/routes/、console-ui/public/) 📍 票:Leo/Arcrun#100
