 ## [Unreleased]
 
+### Added
+
+- 三個 WC runtime usermeta 欄位進 `user`/`hot` group：`wc_last_active`、
+  `wc_order_count_<blog-prefix>`、`last_update`。先前未註冊，這些高頻欄位
+  會落回 `wp_usermeta`。
+- `tests/integration/`：bootstrap（複用核心的 integration bootstrap，連真實
+  MariaDB）+ `phpunit-integration.xml` + CI job，移植 `WCTermCountFilterTest`
+  （18 tests）。
+
+### Notes
+
+- `wc_order_count` 走 WooCommerce 的 `Users::update_site_user_meta()`，實際
+  key 是 `'wc_order_count' . '_' . rtrim( get_blog_prefix(), '_' )`。來源外掛
+  寫死主站形式 `wc_order_count_wp`，multisite 子站（`_wp_2`）會漏接；此處用
+  同一條運算式算出來。
+
 - Phase 3 implementation in progress.
