/**
 * POST /kbdb/records/backfill-library + GET .../status proxy 測試（Arcrun#87 二次收尾，2026-08-13）
 *
 * 背景：基本盤 kbdb/src/routes/records.ts 新增了三元組版的批次標庫補存量端點
 * （backfillTripletLibraryTags——藏書地圖讀的是三元組 record 自己的 'library' slot，跟
 * entries 版 backfill-library 補的 metadata_json.library 是不同存放處）。這條 cypher proxy
 * 之前完全沒轉發這兩支——同 kbdb-records-patch-proxy.test.ts 那次的破口（能力在 base，
 * 插件/工作流打不到）。純轉發，owner_id 強制用租戶身份（不信任 caller 自帶 owner_id，
 * 同本檔既有 POST /kbdb/records 的慣例）。
 *
 * 驗證 IO 接線（聚合真身在 KBDB 基本盤，這裡只測轉發，比照 kbdb-records-patch-proxy.test.ts 慣例）：
 *   1. 租戶閘：無 X-Arcrun-API-Key → 401 不碰 KBDB
 *   2. body 沒有 library → 400，不轉發
 *   3. 轉發：owner_id 一律用租戶身份覆蓋（即使 caller 自帶了別的 owner_id 也被忽略）
 *   4. GET status：owner_id 同樣強制用租戶身份，query 參數透傳
 *
 * KBDB 打 fetchMock 假 host＋disableNetConnect——測試絕不外連。
