 ## P2 — portal_user 模型＋認證 API（design §2/§4）｜觸碰：`cypher-executor/`（新 route 檔）
 
-- [ ] seed template `portal_user`＋`portal_library`（init-seed 慣例）
-- [ ] PBKDF2-SHA256 雜湊模組（600k iters、常數時間比對、`pbkdf2-sha256$…` 格式）
-- [ ] `POST /portal/admin/bootstrap`（console owner session 閘）
-- [ ] login/logout/session/改密碼（KV `portal_sess:`、TTL var、每請求回讀 record 驗 status）
-- [ ] admin 用戶 CRUD＋libraries 授權＋庫目錄 CRUD（role=admin 閘）
-- [ ] 登入失敗節流（5 次/15 分鐘，KV TTL）
-- [ ] 順手修 `record-crud.ts` updateRecord grow 路徑漏 owner_id（design §2.2 附帶）
-- [ ] 測試：bootstrap 閘、登入對錯、停用即拒（session 立即失效）、role 閘、雜湊格式、`{tenant}::portal` 子 namespace 隔離（**搜 email 搜不到**）
+- [x] seed template `portal_user`＋`portal_library`（init-seed 慣例）
+  - 實作註（2026-07-14）：種子資料 `cypher-executor/src/lib/portal-seeds.ts`（*-seeds.ts 慣例類別）；
+    冪等 ensure 在 `routes/portal.ts` `ensurePortalTemplates()`，掛進 `POST /init/seed`（回應加
+    `portal_templates` 區塊）＋ bootstrap 前自動 ensure（沒跑過 seed 也能 bootstrap）。
+- [x] PBKDF2-SHA256 雜湊模組（600k iters、常數時間比對、`pbkdf2-sha256$…` 格式）
+  - `cypher-executor/src/lib/portal-auth.ts`（WebCrypto deriveBits；verify 從儲存格式解析 iterations
+    → 換 KDF/參數可共存漸進遷移；constantTimeEqual 同 mcp PR#15 實作）。
+- [x] `POST /portal/admin/bootstrap`（console owner session 閘）
+- [x] login/logout/session/改密碼（KV `portal_sess:`、TTL var、每請求回讀 record 驗 status）
+  - `PORTAL_SESSION_TTL` 進 wrangler.toml [vars]＋types.ts（預設 604800）。
+- [x] admin 用戶 CRUD＋libraries 授權＋庫目錄 CRUD（role=admin 閘）
+  - 安全註：admin 操作目標 record 需過「email head entry 指回同 record_id」成員驗證（防拿任意
+    record_id 改到不相干 KBDB record）；列表/回應一律剝除 password_hash；未帶密碼建帳號 →
+    server 產一次性密碼隨回應回傳一次（不落地明碼）。
+- [x] 登入失敗節流（5 次/15 分鐘，KV TTL）
+- [x] 順手修 `record-crud.ts` updateRecord grow 路徑漏 owner_id（design §2.2 附帶）
+  - 修法：首查 JOIN entries 帶回 record 既有 owner_id，grow 的新 entry 沿用。回歸測試
+    `kbdb/tests/record-grow-owner.test.ts`（3 項：帶 owner/原無 owner 維持 null/非 grow 不 INSERT）。
+- [x] 測試：bootstrap 閘、登入對錯、停用即拒（session 立即失效）、role 閘、雜湊格式、`{tenant}::portal` 子 namespace 隔離（**搜 email 搜不到**）
+  - 單元：`cypher-executor/tests/portal-auth.test.ts` 20 項（fetchMock 假 KBDB host，絕不外連）；
+    cypher 全套 133/134（唯一失敗＝executor「不存在的零件」pre-existing，stash 複驗）；kbdb 20/20；
+    兩包 tsc exit 0。端到端：本機雙 worker（隔離 persist）33/33 全綠，含**搜尋隔離實測**
+    （租戶 ns 搜 email/雜湊 0 筆＋對照組 leo::portal 搜得到＝非假綠）與明碼落地抽查 0 筆。
 - **驗收**（=#25 驗收）：新增用戶能登入；停用登入被拒＋既有 session 失效；KBDB 無新表；密碼抽查非明碼
 - **工程量**：中（約 1 個 CC 工作天）
