fix(2meet-data-optimizer): keep registered fields out of the public listings REST endpoints

- show_in_rest defaulted to true, so GET /wpdo/v1/listings and /listings/{id} (public by design) returned every registered hot / cold field to anonymous visitors — e.g. infocards tmeetic_ig_access_token_enc / _token_expiry / _user_id and WooCommerce _purchase_note (confirmed on dev36)
- Fields are private unless registered with show_in_rest => true; protected (underscore) and credential-like keys (token, secret, password, api key, private key, credential, salt, nonce) are never exposed
- Zone A list path no longer returns whole rows when nothing is public, and filters / orderby accept public columns only
- Version 1.1.1; CHANGELOG, readme
- Verify: unit 690 (+3), integration 525 (+3 private-column tests, RED on 1.1.0), live suite rest 2/2 (RED on 1.1.0), all live 49/49, phpcs 0, stan OK

+## [1.1.1] — 2026-09-26 — Security：公開 REST 不再回傳私有欄位
+
+**性質**：安全修正（Critical）。1.0.x 起即存在；1.1.0 zip 已撤回（`dist/withdrawn/`）。
+
+### Security
+
+- **公開的 `GET /wpdo/v1/listings`、`/wpdo/v1/listings/{id}` 會把所有已註冊的 hot / cold
+  欄位回傳給未登入者**：`TMDO_Schema_Registry::register()` 的 `show_in_rest` 預設為 true，
+  而 addon 都沒有設定它。dev36 實測可取得 infocards 的 `tmeetic_ig_access_token_enc`、
+  `tmeetic_ig_token_expiry`、`tmeetic_ig_user_id`，以及 WooCommerce 的 `_purchase_note`。
+  - `show_in_rest` 預設改為 **false**：要公開的欄位必須明確宣告。
+  - 受保護的 meta key（底線開頭）與名稱像憑證的 key（token、secret、password、api key、
+    private key、credential、salt、nonce）即使宣告公開也一律不輸出
+    （`TMDO_Schema_Registry::rest_exposable()`）。
+  - Zone A 列表路徑在沒有任何公開欄位時不再回傳整列（fail-closed）；篩選參數與 orderby
+    只接受公開欄位，避免藉由篩選 / 排序推測隱藏值。
+- **相容性**：依賴預設公開的欄位，現在需在註冊時加上 `'show_in_rest' => true`，或使用
+  既有的 `tmdo_rest_listing_visible_fields` filter。
+- 測試：`RestApiTest` 新增 3 個；live suite `rest`（未登入 GET 不得出現私有 / 憑證類 key）。

+`docs/adr-004-search-index-mode-for-hp-wc.md`；搭配 HivePress AddOn 0.2.0。
+
+### Added

+- **Promotion Guard**（`TMDO_Promotion_Guard`）：HivePress 啟用時 post / user / term /
+  comment、WooCommerce 啟用時 post / user 不得升到 aeav_only 或執行 cleanup
+  （`WP_Error( 'promotion_guarded' )`，filter `tmdo_promotion_guard_allow`）；已在
+  aeav_only 的站只顯示後台 notice。（PR-053）
+- **`wp tmdo repair-array-literals [--entity] [--confirm]`**：把扁平表中的 `"Array"`
+  從原生修回；原生也被污染的列出清單。（PR-055）
+- **`bridge-restore-native --overwrite / --only-missing`**：預設依模式（aeav_only 覆寫、
+  其他只補缺）；報告新增 `missing` / `differs` / `same` / `default_skipped`。（PR-058）

+### Changed
+

+  `added_ / updated_ / deleted_{type}_meta` 從原生重新同步（含 `delete_all`、
+  `update_metadata_by_mid` 改 key）。（PR-057）
+- **shadow_read** 讀原生，並抽樣比對扁平值（`tmdo_shadow_compare_sample_rate`）。（PR-056）
+- **Post query router**：
+  - 全有或全無：OR、多 post type、含已註冊 key 的巢狀 group、type 語意與欄位不符的
+    clause 讓整個查詢維持原生；LIKE 包 `%esc_like%`；`pre_get_posts` priority 1000。（PR-060）
+  - 每個 group 各自 JOIN、不加 GROUP BY；NOT EXISTS 不走狀態 / 日期副本路由。（PR-061）
+  - meta orderby：HivePress `_sort`（NOT EXISTS + EXISTS）形狀、具名 clause、
+    `meta_key` + `meta_value_num`。（PR-062）
+  - routed 搜尋維持 WordPress 的 split query（ID-first）。（PR-062b）
+  - 依扁平欄位排序且有篩選的搜尋改由扁平表驅動（`STRAIGHT_JOIN`，posts.ID tie-break 改讀等值的
+    `post_id`），不再以 temporary table 排序；filter `tmdo_router_flat_first` 可關閉。（PR-062c）
+- `composer phpcs` 改用 `phpcs.xml`（與 CI 相同）。
+
+### Fixed
+
+- shadow_read 下 `update_*_meta()` 回傳 false、原生沒有寫入（資料遺失）。（PR-056）
+- 陣列 / 物件存進 text 欄位變成 `"Array"`；text 超過 255 字元改存 NULL 並記錄
+  `text_overflow`。（PR-055）
+- `bridge-restore-native` 覆蓋較新的原生值（WC 庫存）、替每個 user 捏造預設值列。（PR-058）
+- Cold / Hot 表不存在時，`save_post`、`loop_start`、刪除文章仍查詢它們（DB error）。（PR-054、PR-054b）
+- 刪除 post / user / term / comment 後，扁平表留下全 NULL 的孤兒列（PR-057 的 NULL 同步會重建已刪的列）。（PR-057b）
+- Router：Q05（wp_core 與另一 group 的 key 並用）`Unknown column`；OR / 多 post type /

+## [1.0.2] — 2026-08-15 — NinjaFirewall 相容性：WAF 設定選項保護
+
+**性質**：防禦性修正 + 文件。無 schema 變更，無破壞性變更。
+
+### Added
+
+- **`docs/WAF-COMPATIBILITY.md`** — NinjaFirewall (WP Edition) 4.9 相容性評估
+
+  結論：兩者可共存，**不需要開發 AddOn**（NinjaFirewall 全 codebase 零個
+  `apply_filters('nfw_*')` / `do_action('nfw_*')`，官方相容手段全在部署層）。
+  文件涵蓋 WP WAF 與 Full WAF 的模式差異、symlink 多租戶部署的必要設定、
+  三條開發約束，以及實測風險矩陣。
+
+- **`TMDO_Options_Manager::PROTECTED_OPTIONS`** 常數與註冊守衛
+  （`modules/options/class-tmdo-options-manager.php`）
+
+  `register_settings_group()` 會以 `pre_update_option_{key}` 回傳 `$old_value`，
+  讓選項不再落地 `wp_options`、改存專屬設定表。但 NinjaFirewall 的 Full WAF 走
+  `auto_prepend_file`，在 WordPress 載入前就以**原生 mysqli 直查 `wp_options`**
+  取 `nfw_options` / `nfw_rules`。一旦這些鍵被重導向，WAF 會讀不到設定而
+  **靜默停止防護 —— 不報錯、不寫 log**。
+
+  現以 `PROTECTED_OPTIONS`（`nfw_options` / `nfw_rules` / `nfw_checked`）在註冊
+  階段擋下，並發出 `_doing_it_wrong()`。守衛置於方法開頭，全部鍵都被擋時提前
+  返回，不再建立空的設定表。
+
+  註：autoload 最佳化不受影響 —— `optimize_autoload()` 只改 `autoload` 欄位、
+  不刪列，而該處的 `SELECT *` 不看 autoload。
+
+- **`tests/unit/OptionsManagerProtectedTest.php`** — 4 tests / 10 assertions
+
+  鎖住「受保護鍵絕不會被掛上 `pre_option_*` / `pre_update_option_*` 攔截」這個
+  核心保證，並驗證全數受保護時不對資料庫發出查詢。
+
+### Changed
+
+- **Migration Wizard 輪詢間隔 500ms → 2s**（`admin/assets/wpdo-migration-wizard.js`）
+
+  原本 2 req/s 打同一個 REST endpoint，容易觸發 WAF 的 rate-limit 與 bot 偵測。
+  改為 2 秒，與四個 stress-test 面板既有的輪詢節奏一致。
+
+---

 ## [1.0.1] — 2026-08-08 — Schema Registry 冪等性修正（cold zone 欄位重複累積）

 The Entity Bridge and the Zone system coexist; the Sync Bridge's
 `is_owned_by_entity_bridge()` guard prevents duplicate writes.
 
+**Write order (v1.1.0).** In `dual_write` / `shadow_read` the Hook Bus pre-filters
+only decide the route and return `null`: WordPress writes native meta itself, and the
+flat value is then re-synced *from native* in `added_/updated_/deleted_{type}_meta`
+(priority 1) — `TMDO_Hook_Bus::sync_from_native()` reads the first native row with
+direct SQL; no native row → flat NULL. `aeav_only` keeps the pre-filter short-circuit.
+
+**shadow_read** reads native meta (WordPress meta cache) and compares a sample of reads
+with the flat value (`tmdo_shadow_compare_sample_rate`, default 0.1). Flat tables serve
+queries only: `TMDO_Post_Query_Router` is active from `shadow_read` up.
+
+**Search-index mode** (ADR-004). On HivePress / WooCommerce sites native meta is the
+source of truth and flat tables are its search index: `TMDO_Promotion_Guard` refuses
+`aeav_only` and cleanup there (post/user/term/comment with HivePress, post/user with
+WooCommerce), because both read meta with an empty key and WooCommerce updates stock
+and sales with direct SQL. Override: filter `tmdo_promotion_guard_allow`.
+
+**Post query router rules.** A query is rewritten only when the flat table returns
+what native `meta_query` would: every registered clause routable (else the whole query
+stays native), AND relation, one post type, column type matching the clause's CAST
+semantics, LIKE as `%esc_like%`. Meta ordering (the HivePress `_sort` NOT EXISTS/EXISTS
+shape, a named clause, `meta_key` + `meta_value_num`) is routed only as the sole
+`orderby` on a column that orders like native.

+### Lessons learned（WAF）
+
+- **`__DIR__` 會解析 symlink**。NinjaFirewall Full WAF 用 `dirname(dirname(dirname(__DIR__)))`（`lib/firewall.php:78`）推導站台位置，在 symlink 共享 codebase 的 SaaS 架構下，所有租戶都會被判定成「共享目錄所屬的那個站」，於是連錯資料庫、撈不到自己的 `nfw_options`，回錯誤碼 6（訊息寫作 `#3`）。**per-site 的可靠錨點是 `$_SERVER['DOCUMENT_ROOT']`**（web server 的 root 指令值，不受 symlink 影響），這正是 `.htninja` 的搜尋基準。
+- **`.htninja` 放在 `dirname(DOCUMENT_ROOT)` 可服務全部租戶**（`firewall.php:47-48` 的第二順位），因為內容以 DOCUMENT_ROOT 動態推導，一份檔案通用。切勿在其中寫 `return` —— `'ALLOW'` / `'BLOCK'` 是有意義的回傳值。
+- **`NFW_LOG_DIR` 對 WP WAF 模式同樣必要**：L78 的誤判在兩種模式都存在，只是 WP WAF 不用它連 DB，但 log / cache / session 仍會全部寫進共享目錄互相覆蓋。
+- **WAF 失效是靜默的**。讀不到設定時 `nfw_quit()` 直接返回，不擋任何請求也不寫 log —— 「your site is not protected」是字面意思。因此任何會讓 `nfw_options` 離開 `wp_options` 的機制（例如本外掛的 `register_settings_group()` 重導向）都必須擋在註冊階段。
+- **`.user.ini` 必須讓 php-fpm worker 可讀**。dev32 那份是 `root:root 0640`，www-data 讀不到 → `auto_prepend_file` 靜默失效、Full WAF 等同沒裝。排查時容易誤判成「WAF 有在跑」，實際上擋下請求的是共享 mu-plugin 的 WP WAF。
+- **判斷 WAF 是否真的生效，要用會被規則擋的請求實測**（例如 `?x=../../etc/passwd` → 規則 1 → 403），光看首頁 200 或後台無錯誤訊息都不算數。
+- WP-CLI 完全豁免（`firewall.php:18-23`），所以 CLI 全綠**不能**當作「WAF 與外掛相容」的證據，必須另外走 HTTP 驗證。

+## 結論
+
+1. **原生 meta_query 在百萬規模下無法使用。** 任何以 meta 為條件的搜尋都要 14–17 秒，扁平化是必要的，不是錦上添花。
+2. **扁平表的價值集中在「搜尋與篩選」。** 單筆或批次讀 meta（情境 4–6）三種形式都在 1 ms 內，差距可以忽略，而且實務上還有 object cache。
+3. **寬範圍搜尋仍有瓶頸（情境 1，p50 約 0.6 秒、p95 約 3.7 秒）。** 命中 18 萬筆時，優化器選擇全表掃描；再加上 `SQL_CALC_FOUND_ROWS` 要算總數、`ORDER BY post_date` 要排序，還要 JOIN 回 `posts` 過濾狀態。p50 和 p95 差很多，是因為不同的價格區間讓優化器選了不同的執行計畫。
+   - **PR-028**：post 群組表可存 `post_status`、`post_date` 副本與 `(post_status, post_date)` 索引（`wp tmdo post-status-sync`）。1M 列實測：加欄位 0.05 秒（instant）、建索引 5.3 秒、分批（1,000 列）回填 32 秒，之後與 `posts` 0 筆不一致。欄位 collation 必須跟 `posts.post_status` 相同，否則比對會出現 illegal mix of collations。查詢改寫在 PR-029。
+   - **PR-029**：副本 ready 且無 NULL 時，單一 post type、明確狀態、依日期排序的搜尋改為 INNER JOIN、`post_status IN (…)`、`ORDER BY` 副本 `post_date`、不 GROUP BY（bench 變體 `entity+copy`，`--iterations=5`）。仍帶 `SQL_CALC_FOUND_ROWS` 時：情境 1 p50 670→770 ms、**p95 3,739→773 ms**；情境 2 p50 356→448 ms（變慢，因為算總數仍要掃完所有符合列）。拿掉 `SQL_CALC_FOUND_ROWS` 後同形狀情境 1 只要 **8 ms**（走 `idx_post_status_date`、LIMIT 提早結束）→ 完整效益要搭配 PR-030。
+   - **PR-030**：路由後的搜尋不再帶 `SQL_CALC_FOUND_ROWS`；總數改由同一查詢的 `COUNT(*)` 回答，存在物件快取，key 綁 `last_changed(posts)`（核心存文、Hook Bus 扁平寫入都會推進）。1M 實測：快取命中時整頁 **8 ms**（原 694 / 363 ms）；快取失效後第一次為頁面 8 ms + COUNT 608 / 344 ms，與原本相當。任何 post 寫入都讓全部計數失效（WP last_changed 語意），寫入頻繁的站命中率較低。
+4. **Hot 表的索引規則有漏洞。** `add_covering_indexes()` 只替 decimal、tinyint，以及名稱以 `_time` 結尾的 bigint 建索引，所以 `hp_vendor` 沒有索引，情境 3 要 3.4 秒，比 Entity 慢約 12,000 倍。
+5. **Entity 表只有單欄索引。** 情境 2 輸給有複合索引的 Hot 表（337 ms 對 277 ms）。
+   - **PR-027 之後**：群組可用 `register_group( ..., array( 'indexes' => ... ) )` 宣告複合索引。在 1M 列的 Entity 表加上 `cidx_verified_price (hp_verified, hp_price)` 花 8.1 秒；重跑情境 2（`--iterations=10`），Entity p50 從 337 ms 降到 **278 ms**（p95 285 ms），Hot 是 269 ms（p95 280 ms），差距在量測誤差內。執行計畫改走 `e:cidx_verified_price`。
+6. **dual_write 的寫入成本約為兩倍（0.22 ms 對 0.12 ms）**，絕對值很小，不是瓶頸。
+7. **Hot 表和 Entity 表儲存了同一份 listing 資料**（合計約 608 MB），兩者功能重疊。
+
+## 前台與寫入鏈實測（dev36，Release 2.1，2026-09-26）
+
+上面的數字是純 SQL。這一節是真實站台（dev36：HivePress 1.7.31 + Marketplace、WooCommerce 11.1.2、Redis object cache、listing 約 10 萬筆）上的整頁與整條寫入鏈，決策背景見 `adr-004-search-index-mode-for-hp-wc.md`。
+
+**前台搜尋**（`tests/live/tools/fe.sh`：每個 URL 5 次取中位數，`X-S36-Ms` = 整個請求到 `template_redirect`）。「routed」是 post 模式 shadow_read + 核心 2.1 router + HivePress AddOn 0.2.0；「1.0.x」是整合測試當時的 router（報告 `notes/tmdo-integration-test-dev36-2026-09-26.md`）。
+
+| URL | 原生 ms | 1.0.x ms | 2.1 routed ms | ids 與原生相同 |
+|---|---:|---:|---:|---|
+| listing 價格區間 | 614 | 496 | **323** | 是 |
+| listing 價格區間 + `_sort=price__asc` | 975 | 1,062 | **435** | 是 |
+| listing 時薪區間 + `_sort=hourly_rate__desc` | 850 | — | **367** | 是 |
+| listing `_sort=rating__desc` | 1,697 | 1,720 | **866** | 是 |
+| listing 關鍵字 + 價格區間 | 754 | — | 764 | 是 |
+| vendor 時薪區間 | 102 | — | 97 | 是 |
+| WC 商店價格篩選 / 價格排序 | 94 / 111 | 88–94 | 109 / 88 | 是（WC 用 lookup 表，不經 router） |
+
+（R-2.1 驗收，扁平表已從原生回填、含 PR-062c；兩輪量測見 `notes/tmdo-acceptance-2.1-2026-09-26.md`。）
+
+- HivePress 搜尋仍帶 tax_query（排除一個 term），WordPress 因此加上 `GROUP BY posts.ID`，排序需要 temporary + filesort；這是目前 311–428 ms 的主要成本，尚未達到 R-2.1 的 300 ms 目標。
+- PR-062b 之前，routed 搜尋因 `posts_request` 改寫而失去 WordPress 的 split query，改撈整列 `posts.*`：同一條 SQL 撈 `*` 要 590 ms，只撈 ID 為 312 ms。
+- PR-062c 之前，依扁平欄位排序的 routed 查詢由 `wp_posts`（type / status 索引，約 56k 列）驅動、逐筆查扁平表再以 temporary table 排序；拿掉 GROUP BY 或只換 tie-break 都無效（約 300 ms），改由扁平表驅動並把 tie-break 改讀 `post_id` 後只剩單表 filesort：`meta_value_num` 263→147 ms、具名排序 250→142 ms、HP 時薪篩選 + 排序 300→36 ms（只計 SQL）。依日期排序的搜尋由扁平表驅動反而變慢（74→137 ms），所以 flat-first 只用在扁平欄位排序。
+- 量測 gotcha：symlink 切換（`plugins/` → `plugins-dev`）後，PHP-FPM 的 opcache（`revalidate_path=0`）仍執行舊目標的程式，WP-CLI 不受影響；前台數字要先確認實際載入的檔案。
+
+**WP_Query**（`tests/live/tools/qbench.php`，`fields=ids`，20 筆一頁）：價格區間 296→76 ms、價格 + verified 360→53 ms、rating ≥ 4.5 248→33 ms、rate + `_thumbnail_id` EXISTS 24→9 ms；OR、多 post type、無 type 數值比較等維持原生，結果與原生相同。
+
+**寫入鏈開銷**（單一程序，disabled 與 dual_write 交替兩輪取平均）：
+
+| 寫入 | disabled | dual_write | 增加 |
+|---|---:|---:|---:|
+| HP listing | 754 ms / 348 q | 976 ms / 434 q | +29% |
+| WC product | 215 ms / 129 q | 489 ms / 206 q | +127% |
+| vendor（user + post） | 444 ms / 162 q | 630 ms / 230 q | +42% |
+
+WC product 的成本來自 `wc_product` 群組，Release 2.2 移除 WC 扁平化後消失。
+
+## 優化候選（待使用者確認後排入 backlog）
+
+| # | 候選 | 針對 | 預期效果 |
+|---|---|---|---|
+| O-1 | Entity 表把 `post_status`、`post_date` 一併存進來，並建 `(hp_status, post_date)` 等複合索引，讓搜尋不必 JOIN 回 `posts` 排序 | 情境 1、2 | 寬範圍搜尋改為走索引排序，避免 filesort |
+| O-2 | Entity 表支援群組層級的複合索引宣告，例如 `(hp_verified, hp_price)`、`(hp_featured, hp_price)` | 情境 2 | 追上或超過 Hot 表 |
+| O-3 | Hot 表的索引規則補上外鍵型 bigint 欄位（例如 `hp_vendor`） | 情境 3 | 3.4 秒降到 1 ms 以下 |
+| O-4 | 提供總數快取，或讓路由後的查詢可以不跑 `SQL_CALC_FOUND_ROWS`（MySQL 8 已棄用） | 情境 1、2 | 省去每次搜尋都要算出全部符合列的成本 |
+| O-5 | 評估 Hot 表與 Entity 表的整併，避免同一份資料存兩份 | 容量、寫入 | 省下約 229 MB 並減少一次寫入 |

+> 啟用中的 AddOn 會在後台顯示淘汰通知（`TMDO_Deprecated_Addons_Notice`）。
+>
+> HivePress、WooCommerce、LatePoint 是第三方外掛，仍然保留各自的 AddOn。
+
+## 1. 掛上 trait
+
+核心提供 `TMDO_Anti_EAV_Aware` trait（`includes/trait-tmdo-anti-eav-aware.php`）。trait 由核心載入，所以只有在核心存在時才宣告 bridge 類別，把它放在獨立檔案：
+
+```php
+// 2meet-bookings.php（partner 主檔）
+add_action(
+	'plugins_loaded',
+	static function () {
+		if ( ! trait_exists( 'TMDO_Anti_EAV_Aware' ) ) {
+			return; // 核心未啟用：什麼都不做。
+		}
+		require_once __DIR__ . '/includes/class-tmb-tmdo-bridge.php';
+		( new TMB_TMDO_Bridge() )->boot();
+	},
+	3
+);
+```
+
+```php
+// includes/class-tmb-tmdo-bridge.php
+final class TMB_TMDO_Bridge {
+	use TMDO_Anti_EAV_Aware;
+
+	protected function plugin_slug(): string {
+		return '2meet-bookings';
+	}
+
+	public function boot(): void {
+		$this->bind_anti_eav_hooks();
+	}
+
+	// 覆寫需要的 on_register_*()，見下面兩節。
+}
+```
+
+**時機**：核心在 `plugins_loaded:4` 觸發 `wpdo_register_*`，並在 `init:1` 再觸發一次。
+建議掛在 `plugins_loaded:3`，這樣第一次觸發就能收到你的註冊，`init` 之前的讀寫也會被正確路由。
+掛在 `:5` 之後也能運作（會在 `init:1` 補上），只是 `init` 之前的請求看不到你的欄位。
+
+**名稱**：請用 `TMDO_Anti_EAV_Aware`。`WPDO_Anti_EAV_Aware` 是舊的 wp-data-optimizer 3.x 的 trait，由 mu-plugin `wpdo-policy-enforcer.php` 從已退役的路徑載入，沒有後面提到的 `post_types` 參數。
+
+## 2. 註冊自有資料表
+
+讓 `wp wpdo doctor` / benchmark 認得你的資料表，並做 schema 漂移檢查。以 bookings 為例：
+
+```php
+public function on_register_custom_tables( TMDO_Custom_Table_Registry $r ): void {
+	$this->register_custom_table(
+		$r,
+		array(
+			'table_name'       => '2mb_services',   // 不含 $wpdb->prefix
+			'primary_key'      => 'id',
+			'post_type_link'   => null,            // 若每列對應一個 post，填 post_type（playlist 用 'hp_vendor'）
+			'expected_columns' => array(
+				'id'        => 'BIGINT',
+				'vendor_id' => 'BIGINT',
+				'title'     => 'VARCHAR',
+				// …照 CREATE TABLE 逐欄列出
+			),
+			'indexes'          => array(
+				'vendor_id' => array( 'vendor_id' ),
+			),
+		)
+	);
+}
+```
+
+collab、playlist、quotation、mobile-bridge 的 AddOn 只做這件事：把各自 `includes/class-tmdo-<slug>.php` 裡 `register_custom_tables()` 的 `$tables` 陣列**原樣**搬進 partner 的 bridge 即可。
+
+## 3. 註冊 entity 欄位群組（選用）
+
+只有要把 meta 從 `wp_postmeta` / `wp_usermeta` 等 EAV 表移到扁平表時才需要：
+
+```php
+public function on_register_entity_fields(): void {
+	$this->register_entity_fields(
+		'post',
+		'tmb_service_core',
+		array(
+			array( 'key' => 'tmb_price', 'type' => 'decimal', 'searchable' => true ),
+			array( 'key' => 'tmb_status', 'type' => 'enum', 'options' => array( 'open', 'closed' ) ),
+		),
+		array( 'post_types' => array( 'tmb_service' ) )
+	);
+}
+```
+
+- **`post_types`（post 群組建議必填）**：群組只套用在這些 post type。多個群組共用同一個 meta key 時，會依 post 本身的類型決定寫到哪張表；不屬於這些 post type 的 post，這個 key 不受管理（照舊寫原生 meta）。沒有宣告時，共用 key 會被「最後註冊的群組」整個接走。
+- **定義一旦上線就不要改**：欄位定義的 hash 存在 `wpdo_registry_meta`，改了會對已有資料的扁平表執行 ALTER。要新增欄位時，開新群組。
+- **群組名稱不可和別人重複**：同名但定義不同時，後註冊的會被忽略，並在 Site Health、後台 Doctor 分頁和 `wp wpdo doctor` 顯示 `[COLLISION]`。
+
+## 4. 從 AddOn 遷移
+
+1. 在 partner 的 bridge 裡註冊和 AddOn **完全相同**的資料表與群組（直接複製 AddOn 的定義）。
+2. 部署 partner 新版，AddOn 先保持啟用。`wp wpdo doctor` 不應出現 `[COLLISION]`；兩邊定義相同時，重複註冊會被靜默忽略。
+3. 停用 AddOn。
+4. 再跑一次 `wp wpdo doctor`：資料表仍在清單中，而且不應出現 `[ORPHAN]`。如果出現，表示有群組沒有被 partner 接手；該實體是 aeav_only 時，核心會依 `wpdo_registry_meta` 暫時還原它，讓資料可以讀取，但仍應補上註冊。
+5. 確認沒有問題後，刪除 AddOn 外掛。
+
+hub、infocards、spoke 的 partner 外掛本身已經會自己註冊，AddOn 只是重複註冊；停用前照第 2 步確認沒有 `[COLLISION]` 即可。

+# WAF 相容性 — NinjaFirewall
+
+適用：2meet-data-optimizer v1.0.2+ / NinjaFirewall (WP Edition) 4.9
+
+**結論：兩者可共存，且不需要開發 AddOn。** 本文記錄實測結果、symlink 多租戶部署的必要設定、WP SaaS 的開站流程與驗證清單，以及開發時必須遵守的三條約束。
+
+> 只想開新站台的話，直接看 §3；踩到 `Cannot retrieve user options from database (#3)` 看 §2。
+
+---
+
+## 1. 兩種模式的差異
+
+NinjaFirewall 只有兩種模式（「WP+」是付費版本，不是模式）：
+
+| | WordPress WAF | Full WAF |
+|---|---|---|
+| 載入方式 | mu-plugin `0-ninjafirewall.php` | `auto_prepend_file`（`.user.ini` / php.ini） |
+| 執行時機 | WordPress 載入中 | **WordPress 載入之前** |
+| 讀設定 | `get_option('nfw_options')` | 自行解析 wp-config.php，**原生 mysqli 直查 `{prefix}options`** |
+| symlink 安全 | ✅ 站台身分由 WordPress 決定 | ❌ 自行以 `__DIR__` 推導（見 §2） |
+
+這個差異是後續所有注意事項的根源：**Full WAF 完全繞過 WordPress**，因此 TMDO 的任何 PHP 攔截器對它都不存在，但反過來，TMDO 對 `wp_options` 的**持久性**改動會影響它。
+
+---
+
+## 2. Symlink / 多租戶部署（必讀）
+
+WP SaaS 常以 symlink 共享 codebase：
+
+```
+tenant-a/wp-content/plugins -> /shared/plugins
+tenant-b/wp-content/plugins -> /shared/plugins
+```
+
+Full WAF 在 `lib/firewall.php:78` 這樣推導站台位置：
+
+```php
+$nfw_['wp_content'] = dirname(dirname(dirname( __DIR__ )));
+```
+
+**PHP 的 `__DIR__` 會解析 symlink 到真實路徑**，於是每個租戶都被判定為「共享目錄所屬的那個站」。接著 `firewall.php:120-121` 讀到錯誤的 wp-config.php、連到錯誤的資料庫，撈不到該站的 `nfw_options`，最後在 `firewall.php:613` 回傳錯誤碼 6：
+
+```
+NinjaFirewall fatal error: Cannot retrieve user options from database (#3).
+Review your installation, your site is not protected.
+```
+
+最後那句是字面意義的 —— 此時 WAF 已 `nfw_quit()`，**完全不做任何過濾**。
+
+### 解法：以 DOCUMENT_ROOT 為錨點
+
+`.htninja` 的搜尋位置是 `$_SERVER['DOCUMENT_ROOT']`（`firewall.php:47-48`），那是 web server 的 per-site 值，不受 symlink 影響。第二順位是 `dirname(DOCUMENT_ROOT)`，因此**一份檔案即可服務所有租戶**：
+
+```php
+<?php
+// 置於各站 DOCUMENT_ROOT 的共同父目錄，例如 /var/www/Studio/.htninja
+$nfw_site_root = rtrim( $_SERVER['DOCUMENT_ROOT'] ?? '', '/' );
+
+if ( '' !== $nfw_site_root && is_file( $nfw_site_root . '/wp-config.php' ) ) {
+	if ( ! defined( 'NFW_LOG_DIR' ) ) {
+		define( 'NFW_LOG_DIR', $nfw_site_root . '/wp-content' );  // firewall.php:82-83
+	}
+	$wp_config = $nfw_site_root . '/wp-config.php';                // firewall.php:120-122
+}
+
+unset( $nfw_site_root );
+```
+
+覆寫時序：`.htninja` 於 L50 載入 → `NFW_LOG_DIR` 於 L82 生效 → `NFWSESSION_DIR` 跟著 log_dir → `$wp_config` 於 L120 生效。
+
+**注意事項**
+
+- **不要在 `.htninja` 使用 `return`** —— 回傳 `'ALLOW'` / `'BLOCK'` 會改變過濾行為（`firewall.php:54-71`）。
+- `NFW_LOG_DIR` 對 **WP WAF 模式同樣重要**：`firewall.php:78` 在該模式下一樣會誤判，導致所有租戶的 firewall log、`cache/db_hash.N.php`、session 全寫進共享目錄、互相覆蓋。
+- **每個租戶的 DB 都要有自己的 `nfw_options`**。修好路徑後 WAF 會連到正確的租戶資料庫，但該站若從未啟用過 NinjaFirewall，那一列不存在，照樣 #3。開站流程必須包含啟用步驟。
+- `nfw_rules` 約 77KB、`autoload=auto`，每個租戶一份，規則更新也要逐站執行。
+- 若租戶 DB 憑證不在 wp-config.php，可改用 `firewall.php:466-470`：在 `.htninja` 設 `$GLOBALS['nfw_mysqli']` 與 `$GLOBALS['nfw_table_prefix']` 直接提供連線。代價是每 request 多一條 mysqli 連線。
+- **`.user.ini` 必須讓 php-fpm worker（通常是 www-data）可讀**，否則 `auto_prepend_file` 靜默失效、Full WAF 等同未安裝。`root:root 0640` 是常見的踩雷組合。
+
+---
+
+## 3. WP SaaS 開站流程
+
+以 symlink 共享 codebase 的多租戶環境，NinjaFirewall 的每一項設定都分成「平台層做一次」與「每站都要做」兩類。混淆這兩者是最常見的失誤來源。
+
+### 3.1 平台層（全租戶共用，只做一次）
+
+**A. 站台錨點 `.htninja`** — 見 §2。放在各站 DOCUMENT_ROOT 的共同父目錄（例如 `/var/www/Studio/.htninja`），內容以 `$_SERVER['DOCUMENT_ROOT']` 動態推導，因此一份即可服務所有租戶，新增租戶時不需修改。
+
+**B. nginx 規則** — 這是 per-site 設定檔，但內容對所有站相同，建議做成 snippet 讓各站 `include`：
+
+```nginx
+# NinjaFirewall 的 log / cache / loader 目錄。
+# 它自帶的 .htaccess 在 nginx 下完全無效，且 nginx 與 php-fpm 同為 www-data，
+# 檔案權限無法區分「WAF 寫入」與「對外 serve」，因此只能在這裡封鎖。
+# ^~ 是必要的：讓前綴匹配優先於 \.php$ 正則，否則 .php 請求會落到 PHP handler。
+location ^~ /wp-content/nfwlog/ { deny all; }
+
+# 所有 dotfile：.htaccess / .htninja / .user.ini / .env / .git ...
+# 放行 .well-known，否則 Certbot 的 ACME challenge 會失敗、憑證無法續期。
+location ~ /\.(?!well-known) { deny all; }
+```
+
+漏掉這段的後果：`nfwlog/` 下的 `readme.txt` 會被公開讀取（等於告訴掃描器這站跑 NinjaFirewall），未來的 `session/sess_*` 檔也不是 `.php`、同樣裸奔。`.php` 檔本身有雙層保護（引擎開頭的 `die('Forbidden')` + 檔內 `<?php exit; ?>`）不會外洩內容，但不該依賴它。
+
+### 3.2 每個新租戶站台（順序不可顛倒）
+
+**順序很重要**：先確保錨點與設定就緒，再安裝 Full WAF。順序顛倒會直接撞上 §2 的 `#3` 錯誤。
+
+**Step 1 — 啟用外掛，建立該站自己的設定**
+
+```bash
+wp --path=/var/www/sites/<tenant> plugin activate ninjafirewall
+wp --path=/var/www/sites/<tenant> option list --search='nfw*' --fields=option_name,autoload
+#   必須看到 nfw_options 與 nfw_rules，否則後續一定 #3
+```
+
+`nfw_options` / `nfw_rules` 存在**該租戶自己的資料庫**，不會因為 codebase 共享而自動存在。這是 `#3` 最常見的成因 —— 路徑修對了，但那個站從沒跑過 installer。
+
+**Step 2 — 確認目錄權限**
+
+php-fpm worker（通常 www-data）必須能在 `nfwlog/` 建立與寫入檔案：
+
+| 路徑 | 建議 | 理由 |
+|---|---|---|
+| `wp-content/nfwlog/` 及子目錄 | `2775` `wpdev:www-data` | setgid 確保新檔繼承 group；group 需 `w` 否則 WAF 寫不了 log |
+| `nfwlog/` 內檔案 | `664` | 同上 |
+| `nfwlog/session/` | 不用管 | 由 WAF 自建，它會用自己的嚴格權限（`0700`） |
+| `.user.ini`（裝 Full WAF 後才有） | `664` `wpdev:www-data` | www-data 需可讀，否則 auto_prepend 靜默失效 |
+
+```bash
+NFWLOG=/var/www/sites/<tenant>/wp-content/nfwlog
+sudo find "$NFWLOG" -type d -exec chmod 2775 {} +
+sudo find "$NFWLOG" -type f -exec chmod 664 {} +
+```
+
+若 `nfwlog/` 的 owner 本來就是 www-data（例如全程由後台建立），預設 `0755` 也可運作 —— owner 有寫入權。會出事的是「owner 是別人、group 只有 `r-x`」這種組合。
+
+**Step 3 — 安裝 Full WAF（從後台）**
+
+務必從 WordPress 後台操作，不要手工建檔：後台以 www-data 執行，權限天然正確；且官方安裝流程有 sandbox 驗證，會先確認 `auto_prepend_file` 真的生效才寫入設定，避免寫出讓整站 500 的 `.user.ini`。
+
+裝完立刻檢查 `.user.ini` 權限（見上表）。`root:root 0640` 是常見的踩雷組合 —— PHP 讀不到，Full WAF 等同沒裝，而表面上一切正常。
+
+**Step 4 — 套用 nginx 規則並 reload**
+
+```bash
+sudo nginx -t && sudo systemctl reload nginx
+```
+
+### 3.3 開站後驗證（每站必跑）
+
+四項缺一不可。只做前兩項會漏掉最隱蔽的失效模式。
+
+```bash
+SITE=https://<tenant>.example.com
+NFWLOG=/var/www/sites/<tenant>/wp-content/nfwlog
+
+# (1) 模式判別 —— 回 Forbidden 代表 Full WAF 生效（auto_prepend 已套用到所有 PHP 請求）
+curl -sk "$SITE/wp-content/plugins/ninjafirewall/lib/i18n.php" | head -c 9; echo
+
+# (2) 攔截能力 —— 應為 403
+curl -sk -o /dev/null -w '%{http_code}\n' "$SITE/?t=../../etc/passwd"
+
+# (3) 記錄能力 —— 最容易被漏掉的一項，log 必須增長
+before=$(stat -c%s "$NFWLOG/firewall_$(date +%Y-%m).php")
+curl -sk -o /dev/null "$SITE/?t=../../etc/passwd"
+after=$(stat -c%s "$NFWLOG/firewall_$(date +%Y-%m).php")
+[ "$after" -gt "$before" ] && echo "log OK" || echo "log FAIL — 檢查 nfwlog 權限"
+
+# (4) web 封鎖與功能未損
+for p in /wp-content/nfwlog/ /wp-content/nfwlog/readme.txt /.user.ini /.htaccess; do
+  printf "%-40s %s\n" "$p" "$(curl -sk -o /dev/null -w '%{http_code}' "$SITE$p")"   # 全部應為 403
+done
+for p in / /wp-json/ /wp-admin/; do
+  printf "%-40s %s\n" "$p" "$(curl -sk -o /dev/null -w '%{http_code}' "$SITE$p")"   # 200 / 200 / 302
+done
+```
+
+**第 (3) 項為什麼不能省**：攔截與記錄是兩件事。權限不足時 WAF 照樣回 403，但一筆記錄都寫不進去 —— 你得到一個沒有稽核軌跡的防火牆，事故調查時等於沒有。更嚴重的是同一個權限問題會讓 `session/` 建不出來，而 `wl_admin` 管理員白名單靠 `NFWSESSID` session 承載 `nfw_goodguy` 旗標，於是管理員實際上是被全規則掃描的 —— 這正是「後台操作偶爾莫名 403」的來源。
+
+### 3.4 排查時的常見誤判
+
+這幾項在實測中都出現過，全部會誤導判斷：
+
+| 現象 | 直覺結論 | 實際 |
+|---|---|---|
+| 首頁 200、後台沒有錯誤訊息 | WAF 正常 | 完全不能推論。WAF 失效時是 `nfw_quit()` 靜默放行，不擋也不記 |
+| 攻擊 payload 回 403 | Full WAF 生效 | 可能來自共享 mu-plugin 的 WP WAF。用 §3.3 第 (1) 項區分 |
+| `nfwlog/` 下的檔案回 403 | nginx 規則生效 | 也可能是 nginx 以 www-data 開不了 root-only 檔案。修好權限後會突然變 200 |
+| `/.well-known/` 回 403 | dotfile 規則誤擋了 ACME | 多半是目錄存在但 autoindex off。用實檔測：`/.well-known/acme-challenge/<file>` 若回 404（WordPress 頁面）而非 403，代表規則有正確放行 |
+| `wp-login.php` 回 404 | nginx 改壞了 | 檢查是否啟用 `wps-hide-login` 之類的登入頁隱藏外掛 |
+| `wp tmdo doctor` 全綠 | WAF 與外掛相容 | WP-CLI 完全豁免 WAF（`firewall.php:18-23`），CLI 結果不能當相容性證據，必須另外走 HTTP 驗證 |
+
+### 3.5 每租戶獨立的維運負擔
+
+symlink 共享的是 codebase，**不是設定與狀態**。以下每一項都是 per-tenant：
+
+- **`nfw_options` / `nfw_rules`** 存在各自的 `wp_options`。`nfw_rules` 約 77 KB 且 `autoload=auto`，N 個租戶就是 N 份。
+- **規則更新**要逐站執行，沒有集中派送機制。
+- **log / cache / session** 各自獨立（前提是 §2 的 `NFW_LOG_DIR` 已正確設定，否則全部寫進共享目錄互相覆蓋）。
+- **停用租戶站台時**，`nfwlog/readme.txt` 明示：解除安裝後要等 5 分鐘再刪除該目錄，否則站台可能崩潰。
+
+規劃階段就要把這些算進成本 —— 特別是「規則更新要逐站跑」這點，租戶數量上去之後需要自動化。
+
+---
+
+## 4. 開發約束（三條）
+
+### 4.1 不得重導向 WAF 的設定選項
+
+`TMDO_Options_Manager::register_settings_group()` 以 `pre_update_option_{key}` 回傳 `$old_value`，讓選項不再落地 `wp_options`。而 Full WAF 是用原生 mysqli 直查該表 —— 一旦 `nfw_options` / `nfw_rules` 被重導向，WAF 會讀不到設定而**靜默停止防護：不報錯、不寫 log**。
+
+v1.0.2 起由 `PROTECTED_OPTIONS` 常數擋下，測試見 `tests/unit/OptionsManagerProtectedTest.php`。新增任何「WordPress 載入前就會以原生 SQL 讀取 `wp_options`」的第三方元件時，必須把它的設定鍵加進該清單。
+
+**autoload 最佳化不受此限** —— `optimize_autoload()` 只改 `autoload` 欄位、不刪列，而 Full WAF 那句 `SELECT *` 不看 autoload。
+
+### 4.2 不得把 option 名稱字串放進 GET/POST
+
+規則 **322**（`lev=3`，CRITICAL）：
+
+```
+(^|\S['"])nfw_(?:options|rules)\b
+```
+
+任何 GET/POST 值含 `nfw_options` 或 `nfw_rules` 字串即 **403**（why: "Attempt to modify NinjaFirewall settings"）。
+
+這對「列出 autoload 清單讓使用者勾選清理」這類 UI 是直接的地雷 —— 而 `nfw_rules` 正好是最大的 autoload 項目之一，必然出現在清單裡。若要做這種介面，用索引或 hash 當作 POST 值，或直接走 CLI。
+
+### 4.3 不得以 base64 傳送含 SQL 語意的 payload
+
+`nfw_check_b64()`（`firewall.php:1412-1448`，`post_b64` 選項，預設開）會把每個 POST 值 base64 解碼後再比對。明文的 SQL 規則多半需要「以數字/引號開頭」或「以註解結尾」才命中，**base64 版只要「含有」就 CRITICAL 403** —— 涵蓋 `SELECT...FROM...WHERE`、`INSERT INTO`、`UNION SELECT`、`UPDATE...SET`、以及序列化物件 `O:n:"..."`。
+
+換言之，**編碼會讓事情變糟，不是變好**。硬編碼白名單只有 `fpd_print_order` 與 `g-recaptcha-response` 兩個欄位名。
+
+---
+
+## 5. 風險矩陣（實測結果）
+
+於 dev30（**Full WAF**、`wl_admin=1`、`no_restapi=0`、`admin_ajax` 未設）實測。**同一組項目在 WP WAF 模式下結果完全相同** —— 兩種模式都跑過：
+
+| 項目 | 結果 |
+|---|---|
+| `wp tmdo status` / `wp tmdo doctor` | ✅ 不受影響（CLI 豁免） |
+| `GET /wp-json/wpdo/v1/listings`（**無 cookie**） | ✅ 200，且回的是 JSON 而非 WAF 的 HTML 403 頁 |
+| `?hp_price_min=100&hp_featured=1` 動態欄位 filter | ✅ 200 |
+| 首頁 / REST 根 | ✅ 200 |
+| 後台 `/wp-admin/` | ✅ 302（導向登入） |
+| firewall log 中的 TMDO 相關攔截 | ✅ **0 筆**（log 內全部攔截皆為刻意送出的測試 payload） |
+
+最後一項是判斷相容性的核心證據：不是「沒看到錯誤」，而是逐筆檢查 firewall log 的攔截記錄，確認沒有任何一筆來自本外掛的正常操作。
+
+仍需留意的情境：
+
+| 風險 | 觸發條件 | 緩解 |
+|---|---|---|
+| Full WAF 靜默失效 | WAF 設定選項被重導向 | §4.1（已由 `PROTECTED_OPTIONS` 擋下） |
+| 規則 322 誤擋 | option 名稱字串進 GET/POST | §4.2 |
+| migration 中斷 | `run_sync_loop()` 的 110 秒同步 POST（`class-tmdo-migration-orchestrator.php:443` `set_time_limit(120)`）被代理切斷；鎖 `LOCK_TTL_SEC=1800` 才釋放 | 大站用 `force_async=true` 或走 CLI |
+| REST 回 HTML 而非 JSON | 非 administrator 角色，或以 Application Password / JWT 呼叫（無 `NFWSESSID` cookie）→ 不在 `wl_admin` 白名單。403 頁面是 HTML（`firewall.php:1585-1590`），client 端看到的是「JSON parse error」這種難查的錯 | 程式化呼叫走 CLI；或確認帶 cookie |
+| admin-ajax 被當 bot | `admin_ajax` 選項開啟時，缺 `HTTP_ACCEPT` / `Accept-Language` / UA 不含 `Mozilla` 的請求回 **404**（`firewall.php:1760-1802`） | curl / server-to-server 呼叫需帶完整 header；預設此選項未開 |
+
+**WP-CLI 完全豁免**：`firewall.php:18-23` 對 `defined('WP_CLI') && WP_CLI && PHP_SAPI === 'cli'` 直接 `return`。TMDO 全部 63 個 CLI 子命令零風險 —— 這也是 migration、snapshot restore、backfill 等重操作建議走 CLI 的另一個理由。
+
+**管理員幾乎豁免**：`wl_admin=1` 時，帶 `NFWSESSID` cookie 的 administrator 只跑 3 條規則就 `nfw_quit(20)`（`firewall.php:233-252`）。
+
+---
+
+## 6. 為什麼不需要 AddOn
+
+| 理由 | 證據 |
+|---|---|
+| 無對外 hook API | 全 codebase 零個 `apply_filters('nfw_*')` / `do_action('nfw_*')` |
+| 官方相容手段都在部署層 | `.htninja`、`exclude_waf_list` UI、wp-config 常數 —— 沒有一項是 plugin 程式碼掛得上的 |
+| 常見衝突模式在 TMDO 全不存在 | 無 loopback self-POST、無 `db.php`/`object-cache.php` drop-in、無 wp-config 改動、無 `auto_prepend` 操作、無 `$_FILES` 上傳 |
+
+NinjaFirewall 處理「合法外掛送 SQL 被擋」的官方做法是**在引擎裡硬編碼白名單**（例：`firewall.php:1434-1439` 的 JetPack 例外），需向 NinTechNet 回報才會納入，第三方無法自行擴充。
+
+因此本外掛的相容性工作全部落在**核心的三條約束**（§4）與**部署設定**（§2），沒有 AddOn 的著力點。

+# ADR-003：Hot zone 與 Entity 表收斂
+
+- **狀態**：已接受（2026-09-26，選項 A）
+- **日期**：2026-09-26
+- **相關**：`BENCHMARK-SCALE.md`（O-3、O-5）、backlog PR-025〜PR-030
+
+## 背景
+
+post 的高頻欄位有兩套扁平化機制，資料可能存兩份：
+
+| | Hot zone | Entity bridge |
+|---|---|---|
+| 表 | `wp_wpdo_hot_{post_type}`（每個 post type 一張） | `wp_wpdo_post_{group}`（每個群組一張） |
+| 註冊 | `TMDO_Schema_Registry`（zone = hot） | `TMDO_Entity_Registry::register_group()` |
+| 寫入 | `TMDO_Sync_Bridge`（zone 模組進入 dual_write 後） | `TMDO_Hook_Bus`（實體 mode ≥ dual_write） |
+| 查詢改寫 | `TMDO_Query_Router`（`hot_*` 模組 cutover 後） | `TMDO_Post_Query_Router`（post mode ≥ shadow_read） |
+| 生命週期 | 每個 zone 模組 7 狀態 FSM | 每個實體 4 模式（disabled → aeav_only） |
+| 涵蓋實體 | 只有 post | post、user、term、comment |
+| 可完全取代原生 meta | 否（cutover 後原生仍保留） | 是（aeav_only） |
+| 其他 | 單欄 `indexed`、自訂 `data_type` | post_type 範圍（PR-033）、schema hash、衝突偵測、孤兒還原、回寫原生（PR-017/018/031） |
+
+Warm（瀏覽數 TTL）、Cold（JSON blob）、Archive（已刪除文章的 meta）是 Entity 沒有的能力，**不在本決策範圍**，保持原狀。
+
+## 事實
+
+**效能**（100k vendor / 1M listing，`BENCHMARK-SCALE.md`）：
+
+| 情境 | Hot | Entity |
+|---|---:|---:|
+| 價格區間搜尋 p50 | 558 ms | 652 ms |
+| 價格區間 + verified p50 | **277 ms**（有複合索引） | 337 ms |
+| vendor 名下 listing p50 | 3,405 ms（無索引） | **0.28 ms** |
+| 單筆 / 列表預載 | 相同 | 相同 |
+| 容量 | 229 MB | 379 MB |
+
+唯一 Hot 領先的是有複合索引的情境；Entity 支援複合索引後（PR-027）即可追平。
+
+**各站使用現況**（2026-09-26 唯讀查詢）：
+
+| 站 | Hot / Cold 表 | zone 模組 | post entity |
+|---|---|---|---|
+| dev20 / dev21 / dev22 | 無 | 全 idle | aeav_only（dev21 約 400 萬列） |
+| dev23 / 24 / 30 / 31 / 40 | 無 | 全 idle | disabled |
+| dev34（舊 WPDO 1.3.37） | hot_hp_listing 486、hot_hp_vendor 233 | cutover | disabled |
+| dev10 DB（舊版） | hot_hp_listing 491、hot_hp_vendor 231 | cutover | aeav_only（約 3,900 列） |
+
+- **沒有任何 2meet-DO 站在用 Hot zone**；有扁平資料的站全部走 Entity。
+- 只有兩個舊系統的站有 Hot 資料，而它們在 cutover 仍雙寫 postmeta，Hot 表只是副本（PR-022 已確認以 postmeta 為準）。
+
+**只由 Hot zone 註冊、Entity 群組沒有涵蓋的 HP 欄位**：listing / request 的 `hp_drafted`；bookings 的 `hp_start_time`、`hp_end_time`、`hp_quantity`；memberships 的 `hp_expire_period`、`hp_primary`、`hp_expired_time`。
+
+## 選項
+
+**A. 收斂到 Entity（建議）**
+post 高頻欄位只用 Entity。Hot zone 凍結：不再新增註冊，程式碼暫留只為讀取舊資料，確認沒有站使用後再移除。
+
+- 優點：一套路由、一份資料；Entity 能力是 Hot 的超集；現況已經全部在用 Entity，不需要搬資料。
+- 代價：Hot 獨有的欄位（上面那幾個）要改成新的 Entity 群組；情境 2 要靠 PR-027 的複合索引追平。
+
+**B. 兩套並存**
+維持現狀。代價是兩套寫入和查詢路徑都要維護，同一個 key 可能存兩份，O-3 之類的最佳化要做兩次。
+
+**C. 收斂到 Hot**
+不可行：Hot 只支援 post，也沒有 aeav_only、範圍宣告、回寫工具。
+
+## 建議（選項 A）的後續步驟
+
+1. **PR-026（Hot 表 bigint 索引）標為 `[!]` 不做**：沒有站在用 Hot zone。
+2. **PR-027（Entity 複合索引）照常做**：這是情境 2 追平 Hot 的方式。
+3. **新增 PR（HP AddOn）**：把 Hot 獨有的欄位改註冊成新的 Entity 群組（例如 `hp_booking_core`、`hp_membership_core`，以及 listing / request 的補充群組）；既有群組的定義不能改。
+4. **新增 PR（HP AddOn）**：HP adapter 停止註冊 hot 欄位；核心對 zone = hot 的新註冊記錄 deprecated 警告。
+5. **之後**：dev34（PR-022）和 dev10 DB（PR-023）遷出後，再評估移除 `TMDO_Zone_Hot`、`TMDO_Sync_Bridge` 的 hot 路徑與 `TMDO_Query_Router`。
+
+## 決定
+
+**選項 A：收斂到 Entity。**（使用者 2026-09-26 決定）
+
+Hot zone 凍結，依上面的後續步驟執行；backlog 已同步調整（PR-026 標為 `[!]`，新增 HP AddOn 的兩個 PR）。

+# ADR-004：HivePress / WooCommerce 站採「搜尋索引模式」
+
+- **狀態**：已接受（2026-09-26）
+- **日期**：2026-09-26
+- **相關**：dev36 整合測試報告（`notes/tmdo-integration-test-dev36-2026-09-26.md`）、ADR-001、ADR-003、backlog PR-052〜PR-063（Release 2.1）
+
+## 背景
+
+2026-09-26 在 dev36（HivePress 1.7.31 + Marketplace + 10 個擴充、WooCommerce 11.1.2、Redis、10 萬筆 listing）做整合與壓力測試，確認：
+
+1. **HivePress model 與 WC data store 用空 key 讀 meta**（`get_post_meta( $id )`），1.0.x 的 Hook Bus 對空 key 放行、只讀原生。所以 aeav_only 或 cleanup 之後，HP 的 verified / rating、WC 的價格與顧客資料讀成空值（dev20 / dev21 盤點：WC 商品 0/20 可購買）。
+2. **WC 以直接 SQL 更新 `_stock`、`total_sales`**，扁平表跟不上。
+3. **shadow_read 會遺失寫入**：WP 的 `update_metadata()` 經 `get_metadata_raw` 讀舊值，攔截器從扁平表回答，新舊相同就不寫原生。
+4. **Router 在 OR、LIKE、多 post type、跨 group、具名 orderby 上結果錯誤**，HivePress 的 `_sort` 沒被改寫，前台搜尋幾乎沒有變快。
+5. **陣列值被存成 `"Array"`**。
+
+帶 key 的單筆讀取本來就沒有速度優勢：`update_meta_cache()` 一次載入全部 key，之後都是記憶體讀取。扁平表真正的價值在**搜尋與篩選**（`BENCHMARK-SCALE.md` 結論 1、2）。
+
+## 決策（使用者 2026-09-26）
+
+1. **HP / WC 站採「搜尋索引模式」**：原生 meta 是唯一真實資料來源，扁平表是它的搜尋索引。模式最高到 `shadow_read`；`aeav_only` 與 cleanup 由 Promotion Guard 擋下。
+2. **移除 WC 扁平化**（Release 2.2：core 的 `post/wc_product` 群組、WC AddOn 的 user `hot` 群組與 hot-zone 欄位）。
+3. **既有 aeav_only 站（dev20 / 21 / 22）先唯讀盤點**，處置由使用者決定（`notes/ops-aeav-sites-audit-2026-09-26.md`）。
+4. **分兩版**：2.1 = 止血 + 資料正確性 + Router 與 HP 排序；2.2 = 範圍收斂 + 漂移偵測 + CLI 與診斷。
+
+## 設計（Release 2.1）
+
+### 寫入：扁平表跟隨原生
+
+- **dual_write / shadow_read** 下，pre-filter（`update_/add_/delete_{type}_metadata`）只做路由判斷後回 `null`，讓 WordPress 自己寫原生。
+- 扁平表在 `added_ / updated_ / deleted_{type}_meta` action（priority 1）裡**從原生重新同步**：直接 SQL 讀原生第一筆 row（`ORDER BY meta_id LIMIT 1`，不經 filter），扁平值 = `to_db( maybe_unserialize( v ) )`，原生沒有 row 時設為 NULL（`TMDO_Hook_Bus::sync_from_native()`）。
+- `delete_metadata( …, $delete_all )`：`deleted_` action 拿到的 object id 是 0，所以在 `delete_{type}_meta` 先記下 object ids。
+- `update_metadata_by_mid()` 改 key：新舊兩個 key 都重新同步。
+- 原生沒有值時只把既有列的欄位設為 NULL，**不新增列**：刪除實體時 adapter 先刪扁平列，WordPress 才逐筆刪 meta。
+- **aeav_only** 保留原本的 pre-filter short-circuit（非 HP / WC 站仍可使用）。
+
+### 讀取：shadow_read = 讀原生、抽樣比對扁平
+
+`intercept_get` 在 shadow_read 回 `$check`（讓 WordPress 讀原生），並以 `tmdo_shadow_compare_sample_rate`（預設 0.1）抽樣比對扁平值、記錄差異。查詢加速不受影響，因為 Router 仍由 `reads_from_flat()`（shadow_read 以上）控制。
+
+### Promotion Guard
+
+`TMDO_Promotion_Guard`，由 `TMDO_Mode_Manager::set()`、`TMDO_Post_Migration::cleanup()` 與 `TMDO_Phase_Cleanup::execute()` 呼叫：
+
+- HivePress 啟用時，post / user / term / comment 不得升到 aeav_only 或執行 cleanup；WooCommerce 啟用時，post / user 不得。
+- 回傳 `WP_Error( 'promotion_guarded' )`；特殊情況用 filter `tmdo_promotion_guard_allow` 放行。
+- 已經在 aeav_only 的站**讀取時不強制降級**（降級會讀到空的原生），只在後台顯示 notice。處置用 `wp tmdo bridge-restore-native <entity> --demote`。
+
+### 回寫原生（bridge-restore-native）
+
+依模式決定策略：aeav_only 預設 `overwrite`（寫入只到扁平表、原生已過期），其他模式預設 `only_missing`（原生可能較新，例如 WC 直接 SQL 寫庫存）。相同的值不重寫；扁平值等於欄位 default 且原生沒有 row 時不寫（不捏造預設值）。
+
+### 序列化值
+
+`text` / `textarea` 遇到陣列或物件時 `maybe_serialize()`，讀出時 `TMDO_Safe_Unserialize`；`text`（VARCHAR(255)）超長存 NULL 並記 `text_overflow`。既有的 `"Array"` 由 `wp tmdo repair-array-literals` 從原生修復。
+
+### Router：只在語意與原生相同時路由
+
+`TMDO_Post_Query_Router`（`pre_get_posts` priority 1000，排在外掛於預設 priority 加的條件之後）：
+
+- **全有或全無**：任何一個已註冊 key 的 clause 不能路由，整個查詢交回 WordPress。不能路由的情況：
+  - top-level OR
+  - 含已註冊 key 的巢狀 group（排序形狀除外）
+  - 多個 post type
+  - 白名單以外的 compare
+  - type 與欄位語意不同：無 type（CHAR）的數值範圍比較、decimal 欄位的 CHAR 比較、text 欄位用 NUMERIC
+- **LIKE** 包成 `%esc_like%`。
+- **每個 group 各自 LEFT JOIN**；扁平表一文章一列（UNIQUE `post_id`），不加 GROUP BY。
+- 狀態 / 日期副本路由遇到 NOT EXISTS 時停用：INNER JOIN 會漏掉沒有扁平列的文章。
+- **排序**（`wpdo_post_sort`）：
+  - **HivePress `_sort` 形狀**：OR 裡剛好是同 key、同 type 的 NOT EXISTS + EXISTS，其中一個具名，並且是唯一的 orderby。這個 group 從 meta_query 移除，改成 LEFT JOIN 扁平表並 `ORDER BY col, ID DESC`；ASC 時 NULL 排最前，與原生相同。
+  - **具名 clause** 作為唯一的 orderby。
+  - **`meta_key` + `meta_value_num`**（字串欄位用 `meta_value`），加上 `col IS NOT NULL`（原生是 INNER JOIN）。
+  - 欄位排序不等於 `CAST( meta_value AS type )` 時退回原生。
+- **flat-first**：依扁平欄位排序、且 routed 條件已要求扁平列存在（同一 group、非 NOT EXISTS）、沒有 `post__in` / `author` 等高選擇性條件時，改寫成 `SELECT STRAIGHT_JOIN … FROM flat INNER JOIN wp_posts`，ORDER BY 的 `wp_posts.ID` 改讀等值的 `post_id`，排序只在一張表完成。依日期排序的搜尋不套用（由 posts 驅動較快）。filter `tmdo_router_flat_first` 可關閉。
+- **維持 WordPress 的 split query**：`posts_request` 移除 `SQL_CALC_FOUND_ROWS`（總數改由快取的 COUNT 回答）會讓 WordPress 以為 request 被改過而撈整列。`split_the_query` 對 routed 查詢恢復 ID-first，`posts_request_ids` 再移除一次 `SQL_CALC_FOUND_ROWS`。
+
+HivePress AddOn 0.2.0 在 post router 啟用時不再綁定舊的 hot-zone `optimize_query` / `optimize_search`。
+
+## 後果
+
+**好處**
+
+- 資料正確性回到 WordPress 原生語意：HP / WC 的空 key 讀取、直接 SQL 寫入都不再造成資料不一致或遺失。
+- 查詢加速保留，而且擴及 HivePress 前台的篩選與排序（實測見 `BENCHMARK-SCALE.md`「前台與寫入鏈實測」）。
+- 任何時候都可以降回 disabled，原生資料完整。
+
+**代價與限制**
+
+- **寫入開銷**：dual_write / shadow_read 每次 meta 寫入多一次原生讀取與一次扁平寫入。dev36 實測 HP listing 整條寫入鏈 +29%、WC product +127%（後者在 2.2 移除 WC 扁平化後消失）。
+- **沒有讀取加速**：帶 key 的單筆讀取仍走原生（WordPress meta cache）。
+- **漂移**：繞過 meta API 的寫入（直接 SQL、Hook Bus 關閉期間的匯入）會讓扁平表過期，Router 會回傳過期的篩選結果。2.2 的 `drift-check` 與重新啟用時的增量 backfill（E01 / E02）處理；在那之前，大量匯入後要重新 backfill。
+- **decimal 欄位搭配 NUMERIC / DECIMAL**：原生先 CAST 成整數（`DECIMAL` 預設 (10,0)），扁平表精確比較，因此帶小數的值在區間邊界上可能不同。dev36 資料沒有這種值。
+- **text 欄位超過 255 字元**存 NULL，這類值的篩選結果會與原生不同（有 `text_overflow` 記錄）。
+- HivePress 搜尋 p50 為 321–866 ms（原生 600–1,713 ms），尚未達到 R-2.1 的 300 ms 目標（驗收：`notes/tmdo-acceptance-2.1-2026-09-26.md`）。價格篩選頁的 SQL 只剩約 75 ms、其餘為頁面渲染；純排序（如 `rating__desc`）必須 LEFT JOIN 保留沒有值的文章，無法 flat-first。
+
+## 不在範圍內
+
+- aeav_only 的空 key 讀取合併（B02）：HP / WC 站不再使用 aeav_only，是否實作依其他站需求決定。
+- Hot zone 的移除（ADR-003 的後續步驟）。

+ * copy of every managed key, and demoting the entity (or uninstalling) would
+ * leave reads on native meta that no longer has the data.
+ *
+ * Rule: afterwards native meta returns what reads return today.
+ *   - A key is written from the group that currently owns it for that entity
+ *     (TMDO_Entity_Registry::get_field(), by post type for posts), so stale
+ *     copies in other group tables never win.
+ *   - Non-NULL values are stored the way WP stores them (maybe_serialize of
+ *     the value Type_Caster returns); a NULL value deletes the native row.
+ *   - Entities with no row in the owning group's table are not touched:
+ *     leftover native rows for them are outside the flat data.
+ *   - A flat value equal to its field default is not written for an entity
+ *     that has no native row (e.g. activity.session_count = 0): that would
+ *     invent native meta the entity never had.
+ *
+ * Policy (which side wins where both hold a value):
+ *   - overwrite    — flat wins; the default in aeav_only, where writes only
+ *                    reached the flat tables and native is stale.
+ *   - only_missing — native wins, flat only fills gaps; the default in every
+ *                    other mode, where native is the source of truth (and may
+ *                    be newer, e.g. WooCommerce stock written with direct SQL).
+ *
+ * Batched by entity id with a cursor option so an interrupted run resumes; a
+ * final pass re-copies rows updated since the first run started. With
+ * $demote the entity then moves to dual_write, which keeps both copies in
+ * step from then on.
+ *
+ * A single group can be written back on its own ($group) and then retired:

+ *     it overwrites the scoped group's column.
+ *   - NULL / missing legacy values leave the scoped column alone (it holds
+ *     the backfill copy, the only data there is).
+ *   - Source rows are left in place; scoped lookups never read them again.
+ *
+ * Batched by entity id with a cursor option so an interrupted run resumes; a
+ * final pass re-copies legacy rows updated since the first run started, then

+* Security: the public GET /wpdo/v1/listings endpoints returned every registered field (show_in_rest defaulted to true), including private values such as integration tokens and WooCommerce purchase notes. Fields are now private unless registered with show_in_rest => true, and protected (underscore) or credential-like keys are never exposed
+* Security: the listings endpoint no longer returns whole rows when no field is public, and only filters / sorts on public columns
+
+= 1.1.0 =
+* Search-index mode for HivePress / WooCommerce sites (docs/adr-004): native meta stays the source of truth, flat tables are its search index
+* Promotion Guard: aeav_only and cleanup are refused while HivePress or WooCommerce is active (filter `tmdo_promotion_guard_allow`)
+* shadow_read reads native meta and samples a flat comparison — fixes lost native writes
+* dual_write / shadow_read: flat values follow native after every write (added_/updated_/deleted_ meta actions, delete_all, key change by meta_id)
+* Arrays in text fields are stored serialized, never "Array"; `wp tmdo repair-array-literals`
+* `wp tmdo bridge-restore-native`: overwrite in aeav_only, only-missing otherwise; no invented default rows
+* Post query router: routes only when the result equals native (OR, several post types, untyped numeric compares stay native), LIKE wildcards, one join per group, no GROUP BY, HivePress `_sort` / named / meta_value_num ordering, WordPress split query kept, flat-sorted searches driven from the flat table (filter `tmdo_router_flat_first`)

+# Live test suite
+
+Tests that must run inside a real WordPress site, because the stubbed
+`tests/integration` bootstrap cannot reproduce:
+
+- WP core meta flows (`update_metadata()` reads the old value through
+  `get_metadata_raw()` before writing — the shadow_read write-loss bug lives there)
+- the SQL that `WP_Query` actually builds, and hook priorities
+- HivePress / WooCommerce behaviour (`pre_get_posts` sort clauses, empty-key
+  meta reads, direct-SQL stock updates)
+
+**Never run against a production site.** Suites create and delete fixtures
+(`tmdo_live_*` users, `tmdo-live-*` terms). Entity modes are overridden in
+process through `pre_option_wpdo_bridge_modes`; nothing is written to
+`wpdo_bridge_modes` or `wpdo_hook_bus_enabled`.
+
+The reference site is dev36 (HivePress + Marketplace + WooCommerce), with this
+plugin symlinked from the `plugins-dev` worktree while developing.
+
+## Run
+
+```bash
+wp --path=/var/www/Studio/wp-local-dev36 eval-file tests/live/run.php <suite> [<suite> ...]
+```
+
+Exit code 0 when every test passed, 1 otherwise. Output per test:
+
+| Status | Meaning |
+|---|---|
+| PASS / FAIL | normal |
+| XFAIL | known bug, test marked `xfail` with the PR that fixes it; not counted as a failure |
+| XPASS | an `xfail` test passed — counted as a failure so the fixing PR removes the marker |
+| SKIP | the site does not register the key / taxonomy the test needs |
+
+## Suites
+
+| Suite | Covers |
+|---|---|
+| `shadow_write` | writes in shadow_read reach native meta (user, term, HivePress listing) |
+| `serialized` | array meta values are stored serialized in flat tables, never "Array" |
+| `resync` | dual_write / shadow_read: flat follows native after every write (4 entities × 2 modes: update, same value, delete, refused writes, stale flat, key rename by meta_id) |
+| `router` | a routed WP_Query returns the same ids, in order, as native (OR, several post types, untyped numeric compares, named orderby, LIKE, keys of two groups, NOT EXISTS with the status/date copy route, meta orderby: HivePress sort shape, named clause, meta_key + meta_value_num); routed SQL has no GROUP BY |
+| `rest` | anonymous GET of the public listings endpoints returns no protected or credential-like field (1.1.1) |
+| `zero_side_effect` | zone tables that were never created are never queried on save / delete |
+
+## Tools (`tools/`)
+
+Benchmark and data-flow helpers used for the 2026-09-26 dev36 integration test.
+Output files go to the current directory (`qbench`) or `$TMDO_LIVE_OUT`
+(default `/tmp`, `run_batch.sh`), never into the repo.
+
+| Tool | Use |
+|---|---|
+| `seed.php` | `wp eval-file seed.php <vendors\|listings\|requests\|reviews\|products\|orders\|terms> <n> [tag]` — seed through real HivePress / WC APIs |
+| `run_batch.sh` | `run_batch.sh <tag> [divisor]` — parallel seeding batch (`TMDO_LIVE_WP_PATH`, `TMDO_LIVE_OUT`) |
+| `clone.sql` | bench only: clone hp_listing rows to reach large scale (`sed "s/__K__/<n>/" clone.sql \| wp db query`) |
+| `checker.php` | `wp eval-file checker.php [entity]` — native vs flat consistency per registered key (SQL only) |
+| `qbench.php` / `qdiff.php` | run 16 WP_Query shapes, then diff two runs (native vs routed): result sets, order, latency, SQL errors |
+| `mut.php` | data-flow mutations through HivePress models, WC CRUD and core APIs; prints native / flat / API values |
+| `fe.sh` + `zz-s36-probe.php` | front-end search probe (`TMDO_LIVE_URL`). Copy the probe into `wp-content/mu-plugins/` only for the run and remove it afterwards; it only answers requests carrying `X-S36-Probe: 1` |
