+## [1.4.2] — 2026-09-28 — 手冊已知問題修正（hardening 2.4.2）
+
+**性質**：修正。無 schema 版本變更；archive 表新增索引（見「升級後」）。來源：`2meet-do-manual.md`
+附錄 F（F-2、F-4〜F-8、F-11）。
+
+### Fixed
+
+- **設定頁會說明模式為何沒有變更**：完整表單與 AJAX 區塊儲存都經 `TMDO_Mode_Manager::set()`，
+  過去忽略它回傳的 `WP_Error`：不安全的跳階或 Promotion Guard 拒絕時，頁面仍顯示「已儲存」、
+  模式卻沒變。現在完整表單在重新導向後顯示拒絕原因（每位使用者一次），AJAX 儲存以錯誤訊息回傳。（PR-135，F-2）
+- **archive 不再重複歸檔**：`wpdo_archive_sweep` 略過已在 archive 表的 meta（依 `original_meta_id`），
+  過去同一筆 meta 每次 sweep 都再寫一列（dev20：300 列只有 150 筆不同）。archive 表新增
+  `idx_original_meta` 索引；`wp tmdo install` 會補上索引並刪除重複列（保留最早一列）。（PR-136，F-6）
+- **entity 健康面板看得到執行中的 backfill**：批次以 `(entity, group)` 參數排程，面板過去只查
+  `(entity)`，永遠看不到、一直提示可開始。（PR-137，F-11）
+- **停用與解除安裝清掉所有排程**：改用 `wp_unschedule_hook()`，連帶參數排程的事件
+  （`tmdo_drift_resync`、backfill 批次）也清除；修正錯誤的 `wpdo_user_stress_test_batch` 名稱，
+  補上 `wpdo_migration_tick`、`wpdo_entity_backfill_batch`、`wpdo_auto_promote_check` 與各壓測批次。
+  解除安裝另外刪除 `tmdo_*` option 及 `tmdo_*` transient。（PR-138，F-4、F-5）
+- 解除安裝被拒絕時的提示改為指向 `wp tmdo bridge-restore-native`（過去說沒有寫回工具）；post
+  壓測工具不再使用已退役的 `wc_product` 表。（PR-139，F-7、F-8）
+
+### 升級後
+
+- 每個站台執行一次 `wp tmdo install`：為 archive 表加上 `idx_original_meta` 並刪除重複的 archive
+  列（刪除重複只在 CLI 執行，web 啟用外掛時不做）。表很大時請在離峰時段執行。
+- **未執行前 archive sweep 會暫停**（沒有索引時 NOT EXISTS 會對每筆候選掃整張 archive 表）。
+  sweep 只複製、不刪 postmeta，暫停不會遺失資料。
+- 解除安裝的 option 清理保留 LatePoint AddOn 的 `tmdo_latepoint_db_version`；設定頁的 AJAX 錯誤訊息
+  不再 2.5 秒後自動消失。（PR-141，驗收修正）
+
+### 已知、未修改
+
+- 已歸檔的 meta 以 `meta_id` 判斷：文章還原、修改後再次丟到回收桶，archive 保留的是第一次的值。
+- post 壓測工具預設仍是 `product`，但 product 已沒有 flat 表，量測會回報 `flat_table_missing`。

+= 1.4.2 =
+* The settings page shows why a bridge-mode change was refused (unsafe jump, Promotion Guard) instead of reporting it saved
+* Archive sweep skips meta already archived; `wp tmdo install` adds an index on original_meta_id and removes duplicate archive rows (the sweep waits until the index exists)
+* Entity health sees a running backfill (batches are scheduled with entity and group args)
+* Deactivate and uninstall clear every scheduled event, including ones scheduled with args; uninstall also removes tmdo_* options and transients
+* The refused-uninstall notice points to `wp tmdo bridge-restore-native`; the post stress tester no longer uses the retired wc_product table
+
 = 1.4.1 =
 * A query ordered by its meta_key among several orderings (or by the key's name) keeps meta_key native; meta_compare_key other than '=' is not routed; a sort group stays when orderby may use it as the primary clause
 * Only standalone posts.ID terms in ORDER BY become flat post_id tie-breaks (FIELD()/IN expressions from other plugins are left alone); PCRE failures keep the original SQL
