chore(2meet-data-optimizer): make the hardening branch pass PHPStan and PHPCS

- CI PHPStan (level 6, baseline for pre-existing debt) failed on 35 errors in
  code added on hardening/2.0: missing iterable value types (PHPDoc only), a
  redundant method_exists() in uninstall.php, and the new WP-CLI commands
  registered as array('Class', 'instanceMethod') — now array(new Class(), ...)
- Local runs had been masked by a PHPStan tmpDir shared with the act CI runner
  (cached container pointing at a removed phar); use a private tmpDir
- Verify: phpstan (private tmpDir) no errors, phpcs clean on changed files,
  phpunit Unit 658 OK; dev22 (running this branch) CLI post-status-sync /
  bridge-restore-native dry runs OK

+## [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 `$old_value`，
+  讓選項不再落地 `wp_options`、改存專屬設定表。但 NinjaFirewall 的 Full WAF 走
+  `auto_prepend_file`，在 WordPress 載入前就以**原生 mysqli 直查 `wp_options`**
+  取 `nfw_options` / `nfw_rules`。一旦這些鍵被重導向，WAF 會讀不到設定而
+  **靜默停止防護 —— 不報錯、不寫 log**。
+
+  現以 `PROTECTED_OPTIONS`（`nfw_options` / `nfw_rules` / `nfw_checked`）在註冊
+  階段擋下，並發出 `_doing_it_wrong()`。守衛置於方法開頭，全部鍵都被擋時提前
+  返回，不再建立空的設定表。
+
+  註：autoload 最佳化不受影響 —— `optimize_autoload()` 只改 `autoload` 欄位、
+  不刪列，而該處的 `SELECT *` 不看 autoload。
+
+- **`tests/unit/OptionsManagerProtectedTest.php`** — 4 tests / 10 assertions
+
+  鎖住「受保護鍵絕不會被掛上 `pre_option_*` / `pre_update_option_*` 攔截」這個
+  核心保證，並驗證全數受保護時不對資料庫發出查詢。
+
+### Changed
+
+- **Migration Wizard 輪詢間隔 500ms → 2s**（`admin/assets/wpdo-migration-wizard.js`）
+
+  原本 2 req/s 打同一個 REST endpoint，容易觸發 WAF 的 rate-limit 與 bot 偵測。
+  改為 2 秒，與四個 stress-test 面板既有的輪詢節奏一致。
+
+---
+
+## [1.0.1] — 2026-08-08 — Schema Registry 冪等性修正（cold zone 欄位重複累積）
+
+**性質**：核心 bug 修復。無 schema 變更，無 API 變更，無破壞性變更。
+
+### Fixed
+
+- **`TMDO_Schema_Registry::register()` 的 cold zone 分支會無限累積重複項**
+  （`includes/class-tmdo-schema-registry.php`）
+
+  三個 zone 索引的寫入方式並不一致：
+  - `hot` → `$this->hot_columns[$post_type][$column] = ...`（以 column 為 key，天生冪等）
+  - `warm` → `$this->warm_fields[$meta_key] = ...`（以 meta_key 為 key，天生冪等）
+  - `cold` → `$this->cold_fields[$post_type][] = ...`（**append，無去重**）
+
+  而 `wpdo_register_fields` 本來就會被觸發多次——核心自身在 `plugins_loaded:4` 觸發，
+  主檔另有 late-bind safety net 於 `plugins_loaded:30` 再次觸發，好讓在 `:6` 之後才
+  bootstrap 的 AddOn 也能趕上；再加上主外掛與其 AddOn 可能同時註冊同一批欄位。
+
+  **實測影響**：某站台 `cold_fields['hp_vendor']` 累積到 **35 筆但只有 9 個相異值**，
+  每個 key 重複 4 次。修正後為 9 筆、零重複。
+
+  修法：cold 分支加入 `in_array( ..., true )` 去重，使 `register()` 對同一
+  `(post_type, meta_key)` 成為冪等操作，與 hot / warm 的既有行為一致。
+
+### 驗證

+> **本外掛只有通用引擎**：4 entity（post / user / term / comment）反 EAV、zone 表、migration、wizard、admin、CLI、REST、snapshot、diagnostic、notifications。HivePress / WooCommerce / LatePoint / 2meet-* 整合層全部在 11 個獨立 AddOn，核心不得引用它們的類別。
+> **共用命名空間刻意保留**：`wp_wpdo_*` 表、`wpdo_` option / cron / hook 前綴、`wpdo/v1` REST namespace 一律不改名 —— 這是資料層零遷移的前提。類別與函式前綴才是 `TMDO_` / `tmdo_`，並以 `class_alias()` 對外保留 `WPDO_*`。
+> HivePress addon detection uses the **WP active-plugins list** as the authoritative signal (addons publish no per-addon class/const; they register via `add_filter('hivepress/v1/extensions', …)`). See `TMDO_HivePress_Detector::detect()` / `active_plugin_files()` in the HivePress AddOn.
+> **測試 harness 隔離**：`TMDO_FSM_GUARD_DISABLED`（integration bootstrap，讓測試可強制 module state）、`TMDO_Routing_Predicate::flush_cache()`、`TMDO_Schema_Manager::flush_table_exists_cache()` 三者是跨測試污染的解法，**不是** production 缺陷的補丁。

+
+---
+
+## Zone
+
+A dedicated storage tier for WordPress postmeta, optimised for a specific access pattern.
+
+| Zone | Slug | Table pattern | Purpose |
+|------|------|---------------|---------|
+| Hot  | `hot` | `wpdo_hot_{post_type}` | Flat columns for search/filter (index-friendly) |
+| Warm | `warm` | `wpdo_warm` | TTL key-value store for counts and transient flags |
+| Cold | `cold` | `wpdo_cold_{post_type}` | JSON blob for display-only fields |
+| Archive | `archive` | `wpdo_archive` | gzip-compressed historical data |
+
+A post type's fields are assigned to exactly one zone via the **Schema Registry**.
+
+---
+
+## Schema Registry
+
+`TMDO_Schema_Registry` — singleton that maps `(post_type, meta_key) → field definition`.
+
+A **field definition** carries `zone`, `column` (flat name), and optional `type`.
+The registry is populated at `wpdo_register_fields` action by integrations and adapters.
+
+---
+
+## Zone Router
+
+`TMDO_Zone_Router` — static dispatch layer introduced in v3.0.1.
+
+Single module that knows how to route `read`, `write`, and `delete_field` to the correct
+zone handler (Hot / Warm / Cold / Archive) given a field definition.
+Also produces canonical **module names** for Feature Flag lookups.
+
+> **Why it exists**: before v3.0.1, routing logic was duplicated across `TMDO_Sync_Bridge`,
+> `TMDO_REST_API`, and two query files.  Extracting it here creates one seam for tests and
+> one place to change zone routing decisions.
+
+Interface (all static):
+```
+TMDO_Zone_Router::module_name(zone, post_type) → string
+TMDO_Zone_Router::read(field, post_id, post_type, meta_key) → mixed
+TMDO_Zone_Router::write(field, post_id, post_type, meta_key, value) → void
+TMDO_Zone_Router::delete_field(field, post_id, post_type, meta_key) → void
+TMDO_Zone_Router::delete_post(post_id, post_type) → void   # v3.4.0: all-zone post cleanup
+```
+
+---
+
+## Routing Predicate
+
+`TMDO_Routing_Predicate` — centralised predicate module introduced in v3.4.0.
+
+Two recurring guard patterns previously scattered across `TMDO_Sync_Bridge`,
+`TMDO_Query_Router`, and the REST API are now a single module:
+
+```
+TMDO_Routing_Predicate::entity_bridge_owns(meta_key) → bool
+TMDO_Routing_Predicate::should_write_to_zone(post_type, zone) → bool
+TMDO_Routing_Predicate::should_read_from_zone(post_type, zone) → bool
+TMDO_Routing_Predicate::should_query_from_zone(post_type, zone) → bool
+TMDO_Routing_Predicate::flush_cache() → void   # test isolation helper
+```
+
+`entity_bridge_owns()` returns true when `TMDO_Mode_Manager::writes_to_flat('post')` AND
+the key is registered in `TMDO_Entity_Registry` for 'post'.  Result is memoised in a
+request-level static cache (`$entity_bridge_cache`) keyed by `meta_key`.
+
+The three `should_*` predicates are thin compositions of
+`TMDO_Zone_Router::module_name()` + the matching `TMDO_Feature_Flags::is_*()` method.
+
+> **Why it exists**: without this module, callers re-implemented the same two-step
+> "module_name then Feature_Flags" pattern inline.  The **deletion test** confirms depth:
+> removing it pushes the repeated guard back into 8+ call sites in Sync_Bridge alone.
+
+---
+
+## Sync Bridge
+
+`TMDO_Sync_Bridge` — zone-aware dual-write dispatcher hooked into the WordPress metadata API.
+
+Intercepts `get/update/add/delete_post_metadata` and `before_delete_post`.
+Calls `TMDO_Zone_Router::read/write/delete_field/delete_post` directly — no private
+I/O wrappers (v3.4.1: delegate methods inlined and removed).
+Uses the **Routing Predicate** for all ownership and activation checks.
+
+The bridge skips fields owned by the **Entity Bridge** to avoid duplicate writes.
+
+Its only private helper is `get_field_cached()` — a request-level Schema Registry
+lookup cache keyed by `post_type:meta_key`.
+
+---
+
+## Module
+
+A named unit whose lifecycle is tracked by the **Feature Flags** 7-state machine.
+Module names follow the convention: `hot_{post_type}`, `cold_{post_type}`, `warm`, `archive`.
+
+`TMDO_Zone_Router::module_name()` is the single authoritative source for this naming.
+
+---
+
+## Feature Flags / 7-state FSM
+
+`TMDO_Feature_Flags` — state machine governing migration lifecycle for each module.
+
+States: `idle → dual_write → backfill → verify → cutover → cleanup → complete`
+
+`is_write_active(module)` returns true for `dual_write` and above.
+`is_read_custom(module)` returns true for `cutover` and above.
+
+---
+
+## Entity Bridge
+
+Newer anti-EAV system (v2.5+) covering user, term, comment, and post entities via a
+**Hook Bus** that intercepts native `*meta()` API calls and writes to flat entity tables.
+
+`TMDO_Mode_Manager` controls per-entity mode: `disabled → dual_write → shadow_read → aeav_only`.
+`TMDO_Entity_Registry` maps `(entity_type, group) → fields`.
+
+The Entity Bridge and the Zone system coexist; the Sync Bridge's
+`is_owned_by_entity_bridge()` guard prevents duplicate writes.
+
+---
+
+## Migration Phase (Strategy pattern)
+
+Interface: `TMDO_Migration_Phase_Interface` (v3.0.1).
+
+Each phase encapsulates a single step of the Entity Bridge migration pipeline:
+
+| Phase class | Slug | What it does |
+|-------------|------|--------------|
+| `TMDO_Phase_Diagnose` | `diagnose` | Records preflight EAV row count / ratio |
+| `TMDO_Phase_Backup` | `backup` | Dumps native meta table to `uploads/wpdo-backups/` |
+| `TMDO_Phase_Demote` | `demote` | aeav_only → dual_write (rollback entry point) |
+| `TMDO_Phase_Install_Schema` | `install_schema` | Creates flat tables via Schema Manager |
+| `TMDO_Phase_Backfill_Bulk` | `backfill_bulk` | Pivots text-only groups via INSERT…SELECT |
+| `TMDO_Phase_Backfill_Unserialize` | `backfill_unserialize` | Row-by-row migration for JSON fields |
+| `TMDO_Phase_Promote_Shadow` | `promote_shadow` | dual_write → shadow_read |
+| `TMDO_Phase_Verify_Sample` | `verify_sample` | Samples entities, compares flat vs EAV |
+| `TMDO_Phase_Promote_Aeav` | `promote_aeav` | shadow_read → aeav_only |
+| `TMDO_Phase_Cleanup` | `cleanup` | Deletes managed keys from EAV table |
+| `TMDO_Phase_Completed` | `completed` | Terminal — marks job done, returns `'done'` |
+
+`TMDO_Migration_Phase_Base` provides shared helpers (`log()`, `get_managed_keys()`,
+`execute_bulk_pivot()`, `values_loose_equal()`).
+
+The **Migration Orchestrator** (`TMDO_Migration_Orchestrator`) injects phase objects and
+calls `execute($job)` in sequence, advancing through the pipeline.
+
+> **Seam**: the interface is the test surface.  A phase can be tested by constructing it
+> with a stub entity type, calling `execute()` with a job array, and asserting on the
+> job's `state`, `log`, and `metrics` — no hooks or DB needed for unit tests.
+
+---
+
+## Standard Post Interceptor (Template Method pattern)
+
+`TMDO_Standard_Post_Interceptor` — abstract base (v3.0.1) for HPCT-inherited interceptors.
+
+Eliminates the three hook methods (`filter_update_meta`, `action_insert_post`,
+`action_delete_post`) that were previously duplicated across four interceptor classes.
+Subclasses declare only:
+
+```php
+public const FIELD_MAP = ['meta_key' => 'flat_column', ...];
+protected function get_post_type(): string { ... }
+protected function get_table_key(): string { ... }
+protected function build_insert_data(int $post_id, WP_Post $post, string $now): array { ... }
+```
+
+Concrete subclasses: `TMDO_Reviews_Interceptor`, `TMDO_Messages_Interceptor`,
+`TMDO_Memberships_Interceptor`, `TMDO_Requests_Interceptor`.
+
+---
+
+## External Partners
+
+`TMDO_Core::EXTERNAL_PARTNERS` (v3.0.1) — PHP class-name constant array listing all
+external plugin integrations that self-register via the Hook Bus.
+
+```php
+['TMDO_Infocards', 'TMDO_Bookings', 'TMDO_Quotation',
+ 'TMDO_Mobile_Bridge', 'TMDO_Collab', 'TMDO_Playlist']
+```
+
+Used in the late-bind priority-30 closure in `2meet-data-optimizer.php` to initialize
+partner integrations only when their plugin class is present.  Single source of truth —
+previously the list existed only inside the closure and diverged from `TMDO_Core`.
+
+---
+
+## HPCT Interceptors Manifest
+
+> **v1.0.0：本節描述的是 AddOn 的內部結構，核心已無此常數。**
+> `HPCT_INTERCEPTORS` 與 `register_hpct_interceptors()` 隨整合層一起搬到
+> `2meet-data-optimizer-hivepress-addon` 的 bootstrap；核心刻意不保留，否則會引用
+> 8 個核心不存在的類別名。下表列的 interceptor ↔ query-handler 配對關係仍然成立。
+
+`TMDO_Core::HPCT_INTERCEPTORS` (v3.4.0) — PHP class-constant array that is the single
+authoritative list of HPCT-inherited interceptor → query-handler pairs:
+
+```php
+TMDO_Reviews_Interceptor::class      → TMDO_Reviews_Query::class
+TMDO_Messages_Interceptor::class     → TMDO_Messages_Query::class
+TMDO_Favorites_Interceptor::class    → null
+TMDO_Memberships_Interceptor::class  → TMDO_Memberships_Query::class
+TMDO_Statistics_Interceptor::class   → null
+TMDO_Requests_Interceptor::class     → TMDO_Requests_Query::class
+TMDO_Listing_Meta_Interceptor::class → TMDO_Listing_Meta_Query::class
+TMDO_LatePoint_Interceptor::class    → null
+```
+
+`register_hpct_interceptors()` iterates this constant; adding a new interceptor requires
+only one entry here — no code change in the registration method.
+
+---
+
+## HPCT (HP Custom Tables)
+
+The plugin this replaces.  Still referenced in import path (`wp tmdo import-hpct`).
+Any "HPCT-inherited" interceptor means it originated in HPCT and was migrated here.
+
+---
+
+## Adapter (HivePress)
+
+> **v1.0.0：這 13 個 adapter 住在 `2meet-data-optimizer-hivepress-addon`，不在核心。**
+> 核心只提供 `TMDO_Schema_Registry` 與 `wpdo_register_fields` 這個 seam。
+
+Each HivePress addon (core, bookings, events, …) has a corresponding
+`TMDO_Hivepress_*_Adapter` that registers its meta keys into the Schema Registry at
+`wpdo_register_fields`.  The adapter is the seam between HivePress and the zone system.
+
+---
+
+## Anti-EAV
+
+The overarching goal: eliminate Entity-Attribute-Value (EAV) reads from `wp_postmeta`,
+`wp_usermeta`, etc. by moving data to flat tables.
+
+Compliance is enforced by `wpdo-policy-enforcer.php` (mu-plugin) and the
+`wp tmdo lint` CLI gate.
+
+---
+
+## Entity Group
+
+A named set of fields registered under one entity type (user / post / term / comment),
+stored as one flat table: `wp_wpdo_{entity_type}_{group_name}`.
+
+Each group has **one row per entity** (keyed on `user_id` / `post_id` / etc.).
+Fields within the group become typed columns; `sanitize_column_name()` produces the
+column name (strips all non-`[a-zA-Z0-9_]` characters — hyphens are removed, not replaced).
+
+Group registration: `TMDO_Entity_Registry::register_group(entity_type, group_name, fields[])`.
+
+Canonical user groups (v3.1.4):
+
+| Group | Table | Purpose |
+|-------|-------|---------|
+| `membership` | `wp_wpdo_user_membership` | Tier, points, expiry |
+| `activity` | `wp_wpdo_user_activity` | Login counters, last-active |
+| `profile` | `wp_wpdo_user_profile` | Bio, avatar, display name |
+| `sso` | `wp_wpdo_user_sso` | Hub token cache, SLO hash |
+| `core_profile` | `wp_wpdo_user_core_profile` | WP first_name, last_name, nickname, description |
+| `social` | `wp_wpdo_user_social` | 15 social platform URLs |
+| `commerce` | `wp_wpdo_user_commerce` | WC billing/shipping + runtime stats (wc_last_active, wc_order_count_wp, last_update) |
+| `hp_user` | `wp_wpdo_user_hp_user` | HP favorites, avatar, hp_verified |
+| `admin_prefs` | `wp_wpdo_user_admin_prefs` | WP default admin-UI keys written by wp_insert_user + extended UI prefs (22 keys total, v3.1.4) |
+
+---
+
+## EAV Floor
+
+The minimum irreducible rows that must remain in the native meta table even after full
+Entity Bridge migration to `aeav_only`.
+
+For `wp_usermeta`, the floor consists of:
+
+| Key | Rows per user | Why irreducible |

+| `wp_capabilities` | 1 | WP core reads directly in `WP_User` constructor (not through `get_user_meta`) |
+| `session_tokens` | 0–N | WP authentication reads sessions directly; Hook Bus cannot intercept session creation safely |
+| `_application_passwords` | 0–1 | WP reads directly during REST auth |
+
+**Theoretical minimum ratio** for a standard WordPress site: `(users + sessions + app_passwords) / users ≈ 1:1.07` (varies by active sessions).

+## WP Admin Prefs
+
+The set of `wp_usermeta` keys that WordPress core writes automatically:
+
+**Written by `wp_insert_user()` for every new user (7 keys)**:
+`rich_editing`, `syntax_highlighting`, `comment_shortcuts`, `admin_color`, `use_ssl`,
+`show_admin_bar_front`, `dismissed_wp_pointers`
+
+**Written on first admin-page visit or explicit user action (extended, registered v3.1.4)**:
+`show_welcome_panel`, `wp_persisted_preferences`, `nav_menu_recently_edited`,
+`wp_dashboard_quick_press_last_post_id`, `edit_*_per_page` variants,
+`community-events-location`, `wp_user-settings`, `wp_user-settings-time`,
+`managenav-menuscolumnshidden`, `metaboxhidden_nav-menus`,
+`dismissed_no_secure_connection_notice`, `meta-box-order_product`
+
+All 22 keys are registered in the `admin_prefs` Entity Group and routed to
+`wp_wpdo_user_admin_prefs` by the Hook Bus when user entity mode ≥ `dual_write`.

+
+計畫檔：`~/.claude/plans/2meet-data-optimizer-ninjafirewall-effervescent-lighthouse.md`
+
+- [x] 評估與 NinjaFirewall 4.9 的相容性 → **不需要開發 AddOn**
+- [x] 診斷 `Cannot retrieve user options from database (#3)` → 與本外掛無關，根因為 symlink 部署
+- [x] 建立 `/var/www/Studio/.htninja`（symlink-safe 站台錨點，全租戶共用）
+- [x] dev30 啟用 ninjafirewall，補上缺失的 `nfw_options` / `nfw_rules`
+- [x] `TMDO_Options_Manager::PROTECTED_OPTIONS` 守衛 + 4 個單元測試
+- [x] Migration Wizard 輪詢 500ms → 2s
+- [x] `docs/WAF-COMPATIBILITY.md`
+- [x] 全套件回歸：591 tests / 1166 assertions OK
+
+### 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。
+
+## 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 |

+# Entity Adapter Cookbook
+
+How partner plugins integrate with `2meet-data-optimizer v1.0.0+` to gain anti-EAV
+benefits without modifying their existing data model.
+
+This is the practical guide. For the canonical vocabulary see `CONTEXT.md`; for the
+two standing architectural decisions see `docs/adr-001-post-entity-source-of-truth.md`
+and `docs/adr-002-dual-write-naming-collision.md`.
+
+---
+
+## ⚡ TL;DR Decision Tree (read this first — v2.1.2 reordered)
+
+The most common mistake is picking Tier 1-3 when Tier 5 was the right answer.
+Ask these questions in order:
+
+```
+Q1. Does the partner plugin have its OWN custom tables / lookup tables
+    that already provide anti-EAV? (HPOS, wc_product_meta_lookup,
+    BuddyPress activity tables, EDD payments, etc.)
+
+    ├── YES → 🟢 TIER 5 (integrate, don't duplicate). STOP HERE.
+    │         Register awareness only. Do not migrate.
+    │         See: TMDO_WooCommerce reference.
+    │
+    └── NO → continue to Q2.
+
+Q2. Is this a brand-new plugin you control end-to-end?
+
+    ├── YES → 🟢 TIER 4 (greenfield, anti-EAV from day 1).
+    │         Use `wp tmdo register-stub <slug>` for boilerplate.
+    │         See: 2meet-inquiries reference.
+    │
+    └── NO (existing plugin with postmeta) → continue to Q3.
+
+Q3. Is the relevant postmeta key heavily queried (filter / sort / search)?
+    Benchmark: > 10k rows OR > 3-condition meta_query OR sort by meta_value.
+
+    ├── YES → 🟢 TIER 1-3 (migrate to a Zone).
+    │         Tier 1 (5 min) for read-only optimization.
+    │         Tier 2 (30 min) for full dual-write.
+    │         Tier 3 (1-2 days) for new entity type.
+    │
+    └── NO → 🟢 LEAVE AS POSTMETA. Premature optimization.
+              Re-evaluate when scale crosses Q3 thresholds.
+```
+
+**Why Tier 5 is FIRST**: at v2.1.2 audit time, every mature plugin we surveyed
+(WC / BuddyPress potential / EDD potential / GravityForms) has its own anti-EAV.
+Defaulting to Tier 1-3 risks the catastrophic "two sources of truth" failure
+mode. See `docs/INTEGRATION_PATTERN_DECISION.md` for the principle.
+
+### How to tell if a partner plugin already has anti-EAV (Tier 5 candidate)
+
+Check these signals in order — any ONE is sufficient for Tier 5:
+
+| Signal | Where to look | Examples |
+|--------|---------------|----------|
+| **Lookup tables** with name pattern `*_lookup` / `*_meta_lookup` / `*_index` | `SHOW TABLES LIKE 'wp_{prefix}_%lookup%'` | `wp_wc_product_meta_lookup`, `wp_wc_customer_lookup` |
+| **HPOS-style migration toggle** (custom table replaces postmeta) | Plugin's settings → "High Performance" or "Custom Tables" feature | WooCommerce HPOS, EDD 3.0 payments |
+| **Dedicated columns instead of meta** in main entity table | `DESC wp_{plugin}_entities` shows `price`, `status` etc. as columns | BuddyPress activity table, MemberPress subscriptions |
+| **Plugin's own search/filter API** that bypasses `meta_query` | `wc_get_products()`, `bp_activity_get()`, `edd_get_payments()` | WC, BuddyPress, EDD all have native APIs |
+| **`*_stats` / `*_aggregate` tables** for analytics queries | `wp_wc_order_stats`, `wp_*_lookup` | WC analytics, MonsterInsights |
+| **db_version option** that hits `dbDelta` migration on plugin update | `wp option get {plugin}_db_version` returns a non-trivial version | Indicates the plugin has its own schema migration story |
+
+If you see **2+ signals** → definitely Tier 5.
+If you see **0 signals** but the plugin has heavy postmeta usage → Tier 1-3.
+If you see **0 signals** and postmeta is light → leave it (Q3 = NO).
+
+**Quick command-line audit**:
+```bash
+# List custom tables for a plugin
+wp db query "SHOW TABLES LIKE 'wp_{prefix}_%'"
+
+# Count postmeta keys the plugin owns (low = likely Tier 5; high = candidate Tier 1-3)
+wp db query "SELECT COUNT(DISTINCT meta_key) FROM wp_postmeta WHERE meta_key LIKE '\\_{prefix}_%'"
+
+# If both numbers are non-trivial → Tier 5 is correct (plugin uses both, but
+# its tables are the truth and postmeta is legacy/secondary).
+```
+
+---
+
+## Three integration tiers
+
+Pick the one that matches your plugin's data model:
+
+### Tier 1 — `TMDO_API` facade（最少改動，5 分鐘）
+
+If your plugin reads/writes `*_meta()` directly today, swap to the facade. This
+gives you future-proofing for free — the day the field migrates to a zone or
+entity adapter, your plugin needs zero changes.
+
+**Before:**
+```php
+$token = get_post_meta( $vendor_id, 'tmeetic_ical_token', true );
+update_post_meta( $vendor_id, 'tmeetic_ical_token', $new_token );
+```
+
+**After:**
+```php
+$token = class_exists( 'TMDO_API' )
+    ? TMDO_API::get_field( $vendor_id, 'tmeetic_ical_token' )
+    : get_post_meta( $vendor_id, 'tmeetic_ical_token', true );
+
+if ( class_exists( 'TMDO_API' ) ) {
+    TMDO_API::set_field( $vendor_id, 'tmeetic_ical_token', $new_token );
+} else {
+    update_post_meta( $vendor_id, 'tmeetic_ical_token', $new_token );
+}
+```
+
+**Real example:** `2meet-courses/includes/class-2meetic-ical.php` (Wave 2 改造).
+
+**Cross-entity:**
+```php
+TMDO_API::get_entity( 'user',    $user_id, 'points' );
+TMDO_API::get_entity( 'term',    $term_id, 'usage_count' );
+TMDO_API::get_entity( 'comment', $comment_id, 'helpful_count' );
+TMDO_API::set_entity( 'user', $uid, 'points', 50 );
+```
+
+**Helper:**
+```php
+TMDO_API::is_field_registered( 'post', 'hp_price' );  // bool
+TMDO_API::trace_storage( 'post', 'hp_price', 'hp_listing' );  // 'zone_hot' | 'postmeta' | ...
+```
+
+### Tier 2 — Schema Registry 註冊（中等改動，30 分鐘）
+
+If your plugin owns specific meta_keys that benefit from Hot zone (search/filter),
+Cold zone (display/JSON), or Warm zone (TTL counter) treatment.
+
+**Implementation:** create one integration class.
+
+```php
+// my-plugin/includes/class-tmdo-myplugin.php
+final class TMDO_MyPlugin {
+    public static function register(): void {
+        // Detect partner plugin (2meet-data-optimizer) — no-op when absent.
+        if ( ! class_exists( 'TMDO_Schema_Registry' ) ) {
+            return;
+        }
+        add_action( 'wpdo_register_fields', array( __CLASS__, 'register_fields' ) );
+        add_action( 'wpdo_register_custom_tables', array( __CLASS__, 'register_tables' ) );
+    }
+
+    public static function register_fields( TMDO_Schema_Registry $registry ): void {
+        $registry->register_many( 'my-plugin', array(
+            // Hot zone (search/filter): flat 1NF column with index.
+            array(
+                'post_type' => 'my_post_type',
+                'meta_key'  => 'my_price',
+                'zone'      => 'hot',
+                'data_type' => 'decimal(10,2) NOT NULL DEFAULT 0',
+                'column'    => 'my_price',
+                'indexed'   => true,
+            ),
+            // Cold zone (description / JSON / display).
+            array(
+                'post_type'   => 'my_post_type',
+                'meta_key'    => 'my_description',
+                'zone'        => 'cold',
+                'cache_group' => 'wpdo_cold_my_post_type',
+                'cache_ttl'   => HOUR_IN_SECONDS,
+            ),
+        ) );
+    }
+
+    public static function register_tables( TMDO_Custom_Table_Registry $registry ): void {
+        $registry->register( 'my-plugin', array(
+            'table_name'      => 'my_custom_table',
+            'primary_key'     => 'id',
+            'post_type_link'  => 'my_post_type',
+            'doctor_callback' => array( __CLASS__, 'doctor_my_table' ),
+        ) );
+    }
+
+    public static function doctor_my_table(): array {
+        global $wpdb;
+        $count = (int) $wpdb->get_var( "SELECT COUNT(*) FROM `{$wpdb->prefix}my_custom_table`" );
+        return array( 'ok' => true, 'message' => "rows: {$count}" );
+    }
+}
+
+// In your plugin's bootstrap:
+add_action( 'plugins_loaded', array( 'TMDO_MyPlugin', 'register' ), 5 );
+```
+
+**Real examples:**
+- `2meet-data-optimizer/includes/integrations/class-tmdo-infocards.php` — 9 fields + 3 tables
+- `2meet-data-optimizer/includes/integrations/class-tmdo-bookings.php` — 7 tables only
+
+### Tier 3 — Custom Entity Adapter（大改動，1-2 天）
+
+If you need cross-entity behaviour (e.g. counter that works on user / term /
+comment uniformly), use the demo entity counter pattern.
+
+**Real example:** `2meet-data-optimizer/includes/integrations/class-tmdo-demo-entity-counter.php`.
+
+**Pattern:**
+```php
+final class My_Counter {
+    public const MODULE = 'entity_my_counter';
+    public const TABLE  = 'wpdo_my_counters';
+
+    public static function install_table(): void {
+        global $wpdb;
+        require_once ABSPATH . 'wp-admin/includes/upgrade.php';

+## FSM lifecycle reference
+
+For Tier 3 entity adapters, drive the 7+1 state machine via CLI:
+
+```bash
+# 1. Install schema (one-time)
+wp tmdo doctor   # verify base tables
+
+# 2. Initial state: idle (do not register feature flag)
+wp tmdo mode-audit | grep entity_my_counter   # should show 'idle'
+
+# 3. Begin dual_write — both native + zone get writes
+wp tmdo mode-set entity_my_counter dual_write
+
+# 4. Run backfill (if you have existing data)
+# (custom script or wp tmdo migrate)
+
+# 5. Verify with shadow_read for 7 days
+wp tmdo mode-set entity_my_counter verify
+wp tmdo shadow-enable entity_my_counter
+
+# Check for diffs
+wp eval 'echo (int) $GLOBALS["wpdb"]->get_var("SELECT COUNT(*) FROM {$GLOBALS[\"wpdb\"]->prefix}wpdo_shadow_diffs WHERE entity_type=\"user\"");'
+
+# 6. Cutover — reads switch to zone
+wp tmdo shadow-disable entity_my_counter
+wp tmdo mode-set entity_my_counter cutover
+
+# 7. After 7 more days, cleanup native rows
+wp tmdo mode-set entity_my_counter cleanup
+
+# 8. Final state — no fallback, zone is source of truth
+wp tmdo mode-set entity_my_counter complete
+
+# Rollback at any time
+wp tmdo mode-set entity_my_counter idle
+```
+
+---
+
+## Anti-EAV lint exemptions
+
+Some patterns require direct SQL by design (one-off migration scans, cron token
+expiry checks). Mark them with `phpcs:ignore` so `wp tmdo lint --strict` accepts them:
+
+```php
+// phpcs:ignore WPDO.AntiEAV.PostmetaScan -- Cron sweeps postmeta to find expiring IG tokens.
+$ids = $wpdb->get_col( $wpdb->prepare(
+    "SELECT post_id FROM {$wpdb->postmeta} WHERE meta_key = 'tmeetic_ig_token_expiry' AND CAST(meta_value AS UNSIGNED) < %d",
+    time() + 31 * DAY_IN_SECONDS
+) );
+```
+
+**Available rules:**
+- `WPDO.AntiEAV.PostmetaScan` — cross-postmeta scan in migration / cron
+- `WPDO.AntiEAV.UsermetaScan` — same, usermeta
+- `WPDO.AntiEAV.PostmetaFallback` — fallback path during graceful degradation
+
+The exemption stays line-local. The lint cannot be silenced for an entire file.
+
+---
+
+## Verification checklist (before merge)
+
+```bash
+# 1. Lint passes strict
+wp tmdo lint --plugin=$(pwd) --strict
+
+# 2. Conflict scan clean
+wp tmdo conflict-scan
+
+# 3. Doctor check (your custom tables registered + healthy)
+wp tmdo doctor
+
+# 4. Tests pass (if your plugin has them)
+./vendor/bin/phpunit
+```
+
+---
+
+## Real-world results (dev10, 2026-04-25)
+
+Production benchmarks measured with 50 hp_listing posts:
+
+| Path | Latency (n=100) | Speedup |
+|---|---|---|
+| Native `get_post_meta()` | 205ms | 1.0x baseline |
+| `TMDO_Listing_Stats::get_view_count()` (Zone B Warm + fallback) | 81ms | **2.51x** |
+| `TMDO_Demo_Entity_Counter::top_n()` (Zone via 1 LEFT JOIN) | 0.19ms / call | **postmeta cannot do efficiently** |
+
+The `top_n` example is the killer use case — sorting 1000s of users by point
+count via postmeta requires a full meta_value scan + filesort. The zone table
+serves it from a covering index in sub-millisecond.
+
+---
+
+## Tier 4: Greenfield plugin — `2meet-inquiries` (v0.5.0)
+
+The cleanest case: a plugin written **from scratch** to be anti-EAV from day 1.
+Use this as a template for all new 2meet-* plugins.
+
+### Why this is the gold standard
+
+| Pattern | What `2meet-inquiries` does | What `bookings`/`courses`/`infocards` had to retrofit |
+|---|---|---|
+| Large structured config | `wp_2mqi_forms.config_json LONGTEXT` (custom table) | Originally postmeta `_eh_inquiry_config` (anti-EAV violation) |
+| Hot-zone meta on hp_vendor | `wpdo_register_fields` — `_tmqi_default_form_id` (bigint, indexed) | Some retrofitted via Schema_Registry Hot Wave 1; others still WP_Query-driven |
+| Sensitive PII | `customer_email_enc BLOB` + `customer_email_hash CHAR(64)` for indexed lookup | Originally separate plugins each rolled own AES wrapper |
+| Audit-trail rows | Dedicated `wp_2mqi_responses` table (1 row per submission) | Older plugins used `wp_postmeta` rows-per-field → EAV blow-up |
+| Analytics events | Dedicated `wp_2mqi_analytics` (event_type, stage_index, session_id) | N/A — most plugins didn't have analytics, would've gone to postmeta if they did |
+| Webhook config | `wp_options` per vendor (autoload=no, low cardinality) | Same |
+
+### Anatomy: 4 custom tables, 0 plugin-owned postmeta keys
+
+```
+wp_2mqi_forms       — form definitions (config_json + counters + slug)
+wp_2mqi_responses   — submitted inquiries (encrypted PII + payload_json)
+wp_2mqi_drafts      — in-progress submissions (token + 14-day expire)
+wp_2mqi_analytics   — funnel events (view, stage_*, submit)
+```
+
+Plus 2 `hp_vendor` fields registered to Schema_Registry Hot zone:
+
+```php
+$registry->register_many( '2meet-inquiries', array(
+    array(
+        'post_type' => 'hp_vendor',
+        'meta_key'  => '_tmqi_default_form_id',
+        'zone'      => 'hot',
+        'data_type' => 'bigint(20) NOT NULL DEFAULT 0',
+        'column'    => '_tmqi_default_form_id',
+        'indexed'   => true,
+    ),
+    array(
+        'post_type' => 'hp_vendor',
+        'meta_key'  => '_tmqi_inquiries_enabled',
+        'zone'      => 'hot',
+        'data_type' => 'tinyint(1) NOT NULL DEFAULT 0',
+        'column'    => '_tmqi_inquiries_enabled',
+        'indexed'   => true,
+    ),
+) );
+```
+
+### Bootstrap pattern (recommended)
+
+```php
+final class TMQI_Plugin {
+    use TMDO_Anti_EAV_Aware;  // ← strict contract; fails to load without it
+
+    public function run(): void {
+        // Register tables on the canonical action.
+        add_action( 'wpdo_register_fields',        array( __CLASS__, 'register_wpdo_fields' ) );
+        add_action( 'wpdo_register_custom_tables', array( __CLASS__, 'register_custom_tables' ) );
+        // ...
+    }
+
+    public static function register_wpdo_fields(): void { /* hot-zone fields */ }
+    public static function register_custom_tables( $registry = null ): void {
+        TMQI_WPDO_Integration::register_tables( $registry );
+    }
+}
+```
+
+### Ground rules followed
+
+✅ **No `update_post_meta()` calls anywhere** — even for hp_vendor metas, we call `TMDO_API::set_field()`
+✅ **No direct `SELECT FROM wp_postmeta`** — `wpdo lint --strict` exits 0
+✅ **All large JSON in custom tables** — `config_json` and `payload_json` columns, never postmeta
+✅ **Sensitive data encrypted** — reuse `TMEETIC_Crypto::encrypt()` (don't roll your own)
+✅ **Indexed search on encrypted columns** — store SHA-256 hash alongside ciphertext
+✅ **Single `do_action( 'tmqi/submitted' )`** — downstream notifiers, analytics, webhook all hook here
+
+### Verification (run on dev10 right now)
+
+```bash
+# Custom tables registered
+wp eval 'echo count(TMDO_Custom_Table_Registry::instance()->for_provider("2meet-inquiries"));'
+# → 4
+
+# Strict lint passes
+wp tmdo lint --plugin=$(wp plugin path 2meet-inquiries) --strict
+# → Success: Anti-EAV lint passed
+
+# Conflict scan
+wp tmdo conflict-scan
+# → 0 conflicts detected
+```
+
+### Takeaway for Wave 2/3 retrofits
+
+When refactoring an existing plugin to be anti-EAV, the question is not "how do
+we shoehorn this into postmeta less?" — it's "**what does the data look like if
+we redesign it like 2meet-inquiries from day 1?**" Then plot a migration path.
+
+For most plugins the answer is: **replace one big postmeta key with one custom
+table row, and register a small number of hot-zone hp_vendor fields for search.**
+
+---
+
+## Tier 5: Integrating with a plugin that has its OWN anti-EAV — `TMDO_WooCommerce` (v2.1.0)
+
+The hardest case: WC core already has anti-EAV (HPOS for orders, `wp_wc_product_meta_lookup`
+for products). WPDO's job is to **integrate, not duplicate**.
+
+### Why this is different from Tiers 1-4
+
+| Aspect | Tier 1-4 (we own the data) | Tier 5 (WC owns it) |
+|--------|---------------------------|----------------------|
+| Custom tables | We define + create | WC defines + creates |
+| Hot-zone fields | Migrated from postmeta to our Hot zone | Already in WC's lookup tables; we just **register awareness** |
+| Doctor probes | We control existence + schema | We probe but don't fix |
+| Schema drift | Our migration tooling | WC's update_db_*() handles |
+| Conflict | None (single owner) | **Risk: shadow lookup tables** |
+
+### Anti-pattern: ❌ DON'T duplicate WC's lookup tables
+
+```php
+// WRONG — creates a parallel system that drifts from WC's truth
+$schema->register( 'woocommerce', array(
+    'post_type' => 'product',
+    'meta_key'  => '_price',
+    'zone'      => 'hot',
+    // ... migrate _price into our wpdo_hot_product table
+) );
+// Now `_price` lives in BOTH wp_wc_product_meta_lookup AND our hot zone.
+// Updates touch one but not the other. Catastrophe.
+```
+
+### Right pattern: ✅ Register awareness, defer to WC's anti-EAV
+
+```php
+// In TMDO_WooCommerce::register_custom_tables():
+foreach ( WC_CORE_TABLES as $name => $meta ) {
+    $registry->register( 'woocommerce', array(
+        'table_name'     => $name,        // wp_wc_product_meta_lookup
+        'description'    => $meta['description'],
+        'doctor_callback' => array( __CLASS__, 'doctor_check' ),
+    ) );
+}
+
+// In TMDO_WooCommerce::register_schema_fields():
+// Register postmeta keys WC STILL uses (the ones not yet migrated to lookups).
+// When `_price` is also in wc_product_meta_lookup, registering doesn't migrate
+// to OUR hot zone — it's just a hint to TMDO_API consumers about "this is hot".
+$schema->register_many( 'woocommerce', array(
+    array( 'post_type' => 'product', 'meta_key' => '_price', 'zone' => 'hot', ... ),
+    // ...
+) );
+```
+
+### Decision tree for new partner integrations
+
+```
+Does the partner plugin store data in postmeta?
+├── NO → already on custom tables → Tier 4 (register tables + done)
+└── YES → does the partner have its own lookup/cache table?
+    ├── NO → Tier 1-3 (we manage migration)
+    └── YES → Tier 5: register awareness only, never duplicate
+```
+
+### Tier 5 checklist for `TMDO_WooCommerce`
+
+- [x] Register all 20 `wp_wc_*` tables to Custom_Table_Registry
+- [x] Add `doctor_callback` that probes existence + row count (not schema diff)
+- [x] Register hot-zone postmeta fields (legacy path only) — WC's lookup is the truth
+- [x] Detect HPOS state via `OrderUtil::custom_orders_table_usage_is_enabled()`
+- [x] When HPOS off → register order postmeta hot fields (`_order_total`, etc.)
+- [x] When HPOS on → DON'T register order postmeta (would be stale)
+- [x] Customer usermeta hot fields registered unconditionally (WC always uses usermeta for these)
+- [x] Subscription product fields conditional on `WC_Subscriptions` OR `wc-linepay-subscription`
+- [x] Own custom table (`wpdo_wc_commissions`) for vendor marketplace tracking
+- [x] Admin notice recommends HPOS when legacy order count > threshold
+- [x] Admin dashboard surfaces commission stats + table health
+
+### What this DOESN'T do (and shouldn't)
+
+- ❌ Migrate `_price` into our hot zone (WC already has wc_product_meta_lookup)
+- ❌ Mirror `wc_orders` into our archive zone (WC handles its own archive)
+- ❌ Intercept `update_post_meta` for product meta (interferes with WC's lookup sync)
+- ❌ Create products / orders / customers (WC's domain)
+
+### When to revisit
+
+- WC drops a lookup table (unlikely but possible) → migrate that field path to Tier 3
+- HPOS becomes default-on → audit our order postmeta registrations and remove
+- New WC subextension introduces meta keys we should register → add to `register_subscription_fields()`

+# Integration Pattern Decision — 2026-04-25
+
+> **2026-09 更新：** 2meet 自家外掛回到「partner 自行註冊」，做法見 `PARTNER-REGISTRATION.md`；對應的 8 個 AddOn 已淘汰。
+
+> **v1.0.0 後記（2026-07-31）：本文結論已被架構拆分取代。**
+> 當時的兩個選項是「集中在核心」vs「各外掛自帶 bridge」。v1.0.0 走的是第三條路：
+> 每個夥伴外掛對應**一個獨立 AddOn 外掛**（`2meet-data-optimizer-<partner>-addon`，共 11 個），
+> 核心完全不認識夥伴外掛。下文的 `class-tmdo-<partner>.php` 一律已搬進對應 AddOn。
+> 本文保留是為了記錄「為什麼不選 per-plugin bridge 檔」這段推理 —— 該理由對 AddOn 邊界同樣適用。
+
+**Trigger**: Step BB audit revealed two parallel patterns for partner plugin integration; need to commit to one.
+
+---
+
+## What I found
+
+| Plugin | Centralized in 2meet-data-optimizer? | Own bridge file? |
+|--------|-----------------------------------|------------------|
+| 2meet-infocards | ✅ `class-tmdo-infocards.php` | ❌ |
+| 2meet-bookings | ✅ `class-tmdo-bookings.php` | ❌ |
+| 2meet-quotation | ✅ `class-tmdo-quotation.php` | ❌ |
+| 2meet-events | ✅ `class-tmdo-events.php` | ✅ `class-tmevents-wpdo-bridge.php` (**duplicate!**) |
+| 2meet-collab | ✅ `class-tmdo-collab.php` | ❌ |
+| 2meet-mobile-bridge | ✅ `class-tmdo-mobile-bridge.php` | ❌ |
+| 2meet-playlist | ✅ `class-tmdo-playlist.php` | ❌ |
+| 2meet-courses | ❌ | ✅ `class-2meetic-courses-wpdo.php` (NEW today, P step) |
+| 2meet-inquiries | ❌ | ✅ `class-tmqi-wpdo-integration.php` (NEW from scratch) |
+
+**Inconsistency**:
+- 7 plugins are integrated centrally (legacy Wave 2 demo pattern)
+- 2 new plugins (today) are integrated decentrally (cookbook Tier 4 pattern)
+- 2meet-events has **both** (silent dedup by registry — works but smelly)
+
+---
+
+## Decision: **Decentralized (own bridge) is the canonical pattern**
+
+### Rationale
+
+1. **Cookbook Tier 4 documents it as the standard** for new plugins (already published)
+2. **Each plugin owns its own data contract** — no cross-plugin coupling in 2meet-data-optimizer
+3. **Easier to ship** — partner plugin can update its registration without bumping 2meet-data-optimizer
+4. **Simpler mental model** — "where do tables get registered? In the plugin that owns them"
+
+### Why we're NOT migrating today
+
+1. **Freeze**: Per `FREEZE_2026-04-25.md`, no risky refactors during freeze
+2. **Working**: All 7 centralized integrations work; registry dedup handles the events double-pattern
+3. **No vendor demand**: Nobody has reported confusion or bugs from the dual pattern
+4. **Risk > reward**: Moving 7 classes touches 8 plugins, requires coordinated version bumps, breaks atomic rollback
+
+---
+
+## Migration plan (when we DO migrate)
+
+Trigger conditions (any one):
+- A new partner plugin can't ship cleanly because of the centralized pattern
+- A bug in the centralized integrations affects multiple plugins simultaneously
+- We hit 10+ partner plugins (currently 9) and the 2meet-data-optimizer integrations dir is too crowded
+
+### Steps (per plugin, ~0.5 day each)
+
+```
+1. Copy /2meet-data-optimizer/includes/integrations/class-tmdo-{slug}.php
+   to /{plugin-slug}/includes/integrations/class-{prefix}-wpdo.php
+
+2. Rename class:
+   - TMDO_Bookings → TMB_WPDO
+   - TMDO_Quotation → TMQUO_WPDO  (etc.)
+   - Keep registration logic identical
+
+3. Wire in {plugin-slug} bootstrap (after main classes load):
+   require_once $dir . 'includes/integrations/class-{prefix}-wpdo.php';
+   {prefix}_WPDO::register();
+
+4. In 2meet-data-optimizer:
+   - Remove require_once line
+   - Remove class name from the partner array (line ~208 of main file)
+   - Bump WPDO version (patch)
+
+5. Verify:
+   wp eval 'echo count(TMDO_Custom_Table_Registry::instance()->for_provider("{slug}"));'
+   → should still match the original count
+
+6. Bump partner plugin version (minor, since it now has new dependency)
+   Update Requires Plugins header to mention 2meet-data-optimizer ≥ X.Y.Z
+```
+
+### Special case: 2meet-events double-pattern
+
+Already has both. Migration = remove the centralized `class-tmdo-events.php` (the bridge in 2meet-events stays). This is the **simplest first migration** because the partner plugin's own bridge is already proven.
+
+---
+
+## What this means for tomorrow's reader
+
+If you're writing a NEW 2meet-* plugin: **follow Tier 4 pattern, put your integration class in your own plugin's `includes/integrations/` directory.**
+
+If you're maintaining an EXISTING centralized integration in 2meet-data-optimizer: **leave it alone unless one of the migration triggers fires.**
+
+If you see the dual pattern in 2meet-events and are confused: **it's intentional, registry dedups, will be cleaned up later.**
+
+---
+
+## Anti-decisions (things explicitly NOT done)
+
+- ❌ NOT moving 7 integrations today — too risky, freeze active
+- ❌ NOT fixing the events double-pattern today — works fine, low priority
+- ❌ NOT writing a "consolidation script" — premature optimization for a one-time migration
+- ❌ NOT updating cookbook to mention the centralized pattern — would be confusing
+
+---
+
+## When to revisit this decision
+
+Same as freeze conditions (`FREEZE_2026-04-25.md`):
+- vendor reports confusion / bug
+- 30 days passed with no action needed
+- New plugin (#10+) onboarded
+- Production critical event involves the pattern

+## 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-001: Post Entity Source-of-Truth Contract
+
+**Status:** Accepted  
+**Date:** 2026-05-15  
+**Deciders:** wpdev  
+
+---
+
+## Context
+
+Two code paths can intercept `update_post_metadata` / `add_post_metadata`:
+
+1. **TMDO_Sync_Bridge** — the original Zone interceptor that dual-writes to
+   Hot (Zone A) and Cold (Zone C) flat tables.
+2. **TMDO_Hook_Bus** — the Entity Bridge write path added in v2.9.x that writes
+   to `wp_wpdo_post_*` flat tables via Entity Registry groups.
+
+When both are active without a clear contract, a single `update_post_meta()` call
+can fan out to three distinct write paths (wp_postmeta + Zone table + entity flat
+table), producing divergent row counts and confusing `TMDO_API::trace_storage()`
+output.
+
+The defensive patch `TMDO_Sync_Bridge::is_owned_by_entity_bridge()` (v2.9.2)
+was added to prevent double-writes but left the authoritative contract undocumented.
+
+---
+
+## Decision
+
+**When `post` entity mode is `dual_write`, `shadow_read`, or `aeav_only`,
+Entity Bridge (TMDO_Hook_Bus) is the sole source of truth for keys registered
+in TMDO_Entity_Registry under the `post` entity type.**
+
+Sync_Bridge defers to Entity Bridge for those keys via `is_owned_by_entity_bridge()`:
+
+```php
+// TMDO_Sync_Bridge — intercept_update() guard:
+if ( self::is_owned_by_entity_bridge( $meta_key ) ) {
+    return $check; // pass-through — Entity Bridge owns this key
+}
+```
+
+`is_owned_by_entity_bridge()` returns `true` when both conditions hold:
+- `TMDO_Mode_Manager::writes_to_flat('post')` — mode is at least dual_write
+- `TMDO_Entity_Registry::get_field('post', $meta_key)` — key is registered
+
+Keys **not** in Entity Registry continue to be owned by Sync_Bridge (Zone path).
+
+### Invariants
+
+| Condition | Owner |
+|-----------|-------|
+| post mode = `disabled` or `idle` | wp_postmeta (no interception) |
+| post mode ≥ `dual_write` AND key in Entity Registry | **Entity Bridge** |
+| post mode ≥ `dual_write` AND key not in Entity Registry | **Sync_Bridge** (Zone) |
+| post mode = `aeav_only` | Entity Bridge for registered keys; unregistered keys fallthrough to wp_postmeta |
+
+---
+
+## Consequences
+
+**Good:**
+- Developers adding a new post meta key can determine its owner in O(1): check
+  whether the key is in `wpdo_register_fields` under `post` entity. If yes →
+  Entity Bridge owns it; if no → Zone Sync_Bridge handles it.
+- `TMDO_API::trace_storage()` output reflects this: Entity Bridge keys show the
+  flat entity table; Zone keys show the zone table.
+
+**Bad / Watch out for:**
+- A key registered in **both** Schema_Registry (Zone) and Entity_Registry (Entity
+  Bridge groups) will be captured by Entity Bridge and silently dropped by
+  Sync_Bridge. The duplicate registration is a misconfiguration — caught by
+  `TMDO_Sync_Bridge` guard and validated by `wp tmdo conflict-scan`.
+- If `TMDO_Mode_Manager` or `TMDO_Entity_Registry` are unavailable (e.g. very
+  early bootstrap), `is_owned_by_entity_bridge()` returns `false` and all writes
+  fall through to the Zone path — safe degradation.

+# ADR-002: Acknowledge 'dual_write' naming collision between Mode_Manager and Feature_Flags FSMs
+
+**Status:** Accepted — deferred rename  
+**Date:** 2026-05-15  
+**Deciders:** wpdev  
+
+---
+
+## Context
+
+Two distinct FSMs in the codebase both use the string `'dual_write'`:
+
+| FSM | Class | Constant | Stored in | Semantics |
+|-----|-------|----------|-----------|-----------|
+| Entity Bridge | `TMDO_Mode_Manager` | `MODE_DUAL_WRITE` | `wpdo_bridge_modes` | Writes go to both UAE flat table AND `wp_*meta` |
+| Zone Migration | `TMDO_Feature_Flags` | `STATUS_DUAL_WRITE` | `wpdo_features` | Writes go to both Zone A/B/C table AND `wp_postmeta` |
+
+The two FSMs are orthogonal — a post type can be in Zone `dual_write`
+(actively migrating) while the Entity Bridge is in `aeav_only` mode, or vice
+versa. The collision was introduced when the Entity Bridge FSM was added in
+v2.5.x alongside the pre-existing Zone Migration FSM.
+
+---
+
+## Decision
+
+**Defer the rename. Document the collision instead.**
+
+Renaming either constant (e.g. Mode_Manager → `bridge_dual`) would require:
+
+1. Updating ~85 call sites across 30+ files.
+2. Writing a DB migration to translate stored option values (`'dual_write'` →
+   `'bridge_dual'` in `wp_options['wpdo_bridge_modes']`).
+3. Updating all WP-CLI commands that accept mode strings as user input.
+4. Updating all admin UI dropdowns and confirmation messages.
+5. Handling sites that run the old code against a DB that has already been
+   migrated (or the reverse — new code on an un-migrated DB).
+
+The risk of introducing bugs via a mechanical rename outweighs the naming
+improvement at the current stage of the project.
+
+The collision is mitigated by:
+- A disambiguating docblock in `class-tmdo-mode-manager.php` (added 2026-05-15)
+- This ADR, which explains the overlap to future developers
+- The two FSMs operating on different option keys and being unreachable from
+  each other's code paths
+
+---
+
+## Consequences
+
+- **Future rename path**: When a DB migration is warranted (e.g. alongside
+  another schema change), rename `MODE_DUAL_WRITE → 'bridge_dual'` and add a
+  migration in `TMDO_Installer::maybe_upgrade()` that rewrites the stored string.
+- **Linter**: If PHPStan or a custom rule ever flags string literal comparisons
+  across FSMs, this ADR is the canonical explanation for why the overlap is
+  intentional.

+# 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）。

+ *     leftover native rows for them are outside the flat data.

+ * TMDO_Post_Group_Reconciler — move post values written under legacy routing.
+ *
+ * Before post_type-scoped routing (tmdo_post_scoped_routing), a meta key
+ * shared by several post groups was read and written through the last group
+ * registered, e.g. a listing's hp_rating lived in wp_wpdo_post_hp_vendor_core.
+ * Scoped lookups read it from the listing's own group instead, so those
+ * values have to be copied there first.
+ *
+ * Rule: after the switch every read must return what it returned before.
+ *   - A non-NULL value in the legacy owner's table is what reads served, so
+ *     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
+ * scoped routing is switched on.

+=== 2meet Data Optimizer ===
+Contributors: 2meetio

+Requires at least: 6.0
+Tested up to: 6.9

+
+Four-zone postmeta optimization for WordPress. Migrates wp_postmeta to dedicated custom tables (Hot/Warm/Cold/Archive) for dramatically faster queries.
+
+== Description ==
+
+**2meet Data Optimizer** replaces the slow, generic `wp_postmeta` EAV table with four purpose-built storage zones, each optimized for a specific access pattern:
+
+| Zone | Name | Best For | Speed Gain |
+|------|------|----------|-----------|
+| A | Hot | Search / filter fields (price, category, status) | 3–12× faster |
+| B | Warm | TTL counters (view counts, temporary flags) | N/A |
+| C | Cold | Display / description fields (JSON blob + Object Cache) | 2–4× faster |
+| D | Archive | Expired data (gzip compressed, restorable) | N/A |
+
+= Key Features =
+
+* **Zero-downtime migration** — 7-state machine (idle → dual_write → backfill → verify → cutover → cleanup → complete) with rollback support
+* **Fully replaces HP Custom Tables (HPCT)** — one-command import of all HPCT flags and migration records
+* **HivePress integration** — automatic field detection for hp_listing, hp_vendor, and 17+ HivePress extensions
+* **LatePoint integration** — booking meta interception
+* **WooCommerce Orders interception** — order meta routing
+* **MySQL / MariaDB + SQLite dual-engine** — works with both the standard MySQL stack and the SQLite drop-in
+* **REST API** — `/wp-json/wpdo/v1/` endpoints for listings, stats, and status monitoring
+* **WP-CLI** — 13 commands: status, install, doctor, analyze, migrate, verify, cutover, rollback, enable, disable, import-hpct, benchmark, cleanup
+* **Rate limiting** — IP transient + cookie-based dedup for POST /view; Admin Dashboard shows Top 10 rate-limited posts
+* **Object Cache integration** — Zone C bulk prefetch on `loop_start` + `save_post` cache warming
+* **Admin Dashboard** — 4-group 20-tab UI: Dashboard / Zones / Migration / Classifier / Entity Bridge / User-Term-Comment-Post migration wizards / Stress Testers / Logs / HPCT Import / REST API / HivePress / Settings
+* **Zone Classifier** — analyzes existing postmeta and suggests optimal zone placement (transient-cached, 1h TTL)
+* **Multisite** — auto-installs tables on new site creation
+* **i18n ready** — `.pot` template + Traditional Chinese (zh_TW) 100% complete
+
+= Real-World Performance (MariaDB 11.8.2, n=200) =
+
+* **hp_listing single-field read**: ~633ms → ~56ms = **12× faster** (Zone A benchmark)
+* **hp_vendor single-field read**: ~334ms → ~108ms = **3.1× faster** (Zone A benchmark)
+* **hp_vendor JSON blob read**: ~270ms → ~87ms = **3.1× faster** (Zone C benchmark)
+* **Query Router T2 full-row get_row**: **28.1× faster**
+* **Query Router T7 multi-field write set_many**: **95.3× faster**
+
+= Requirements =
+
+* WordPress 6.0+
+* PHP 8.1+
+* MySQL 5.7+ / MariaDB 10.4+ (or SQLite via drop-in)
+
+== Installation ==
+
+1. Upload the `2meet-data-optimizer` folder to `/wp-content/plugins/`
+2. Activate the plugin through the **Plugins** screen in WordPress
+3. Navigate to **2meet Data Optimizer** in the admin menu
+4. Run `wp tmdo doctor` (WP-CLI) or click **Run Doctor** in the Dashboard tab to verify installation
+5. Use `wp tmdo analyze {post_type}` to see zone placement recommendations
+6. Use `wp tmdo migrate {module}` to start migrating a module
+
+= Migrating from HP Custom Tables =
+
+1. Keep HP Custom Tables active
+2. Run `wp tmdo import-hpct` to copy all HPCT state
+3. Verify with `wp tmdo doctor`
+4. Deactivate HP Custom Tables
+
+== Frequently Asked Questions ==
+
+= Will my data be lost if I deactivate the plugin? =
+
+No. During the `dual_write` and `backfill` phases, all data continues to be written to `wp_postmeta`. Data in Zone tables is only the primary source after `cutover`. You can `rollback` any module before reaching `complete` state.
+
+= Does this work without WP-CLI? =
+
+Yes. All migration operations are available through the Admin UI under **2meet Data Optimizer → Migration**. WP-CLI is optional but recommended for batch operations.
+
+= Is SQLite supported? =
+
+Yes. The plugin automatically detects the SQLite drop-in (`WP_SQLite_DB` / `WP_SQLite_Translator`) and applies compatibility patches. Zone D gzip archive and Zone A flat columns both work on SQLite.
+
+= Will this conflict with HivePress or HP Custom Tables? =
+
+2meet Data Optimizer loads at `plugins_loaded` priority 4 (before HPCT at priority 5) and includes compatibility logic to prevent duplicate hook registration. Running alongside HPCT is fully supported during the transition period.
+
+= How do I roll back a migration? =
+
+```
+wp tmdo rollback {module}
+```
+
+This reverts to `dual_write` state. All reads return to `wp_postmeta` immediately. You can re-attempt the migration at any time.
+
+= What is the Zone Classifier? =
+
+The Classifier tab analyzes your existing `wp_postmeta` data (access frequency, value cardinality, field length) and suggests which zone each meta key belongs in. Results are cached for 1 hour per post type.
+
+== Screenshots ==
+
+1. Dashboard — overview of all modules, test counts, and rate-limit statistics
+2. Migration — 7-state progress bar per module with migrate/verify/cutover/rollback actions
+3. Zone Classifier — postmeta analysis with zone recommendations
+4. REST API Tab — endpoint documentation with cURL examples and JavaScript SDK
+
+== Changelog ==
+
+= 1.0.0 =
+* Supersedes `wp-data-optimizer` v3.4.6 — that plugin is retired; this one is the single unified engine
+* Version numbering restarts at 1.0.0; entries below 3.4.6 are the predecessor's history, kept for archaeology
+* Security: 7 × Logger::error() arity fatals fixed; REST field allowlist; 13 destructive admin actions moved GET → POST; DDL type whitelist; mass column clear is now opt-in via `wpdo_allow_mass_column_clear`
+* Concurrency: warm table UNIQUE KEY, JSON_MERGE_PATCH / JSON_REMOVE cold writes, atomic Zone_Warm::increment()
+* Architecture: TMDO_Zone_Router + TMDO_Routing_Predicate, Migration Phase Strategy (11 phase classes), TMDO_Standard_Post_Interceptor
+* Compat: bidirectional `wpdo_*` ⇄ `tmdo_*` hook bridge, 57 AddOn class aliases, `wp tmdo` namespace for all 38 CLI subcommands
+* ABI: `doctor_callback` is now 1-arg; `wpdo_capture_before_value` defaults to false
+* Integration layers (HivePress / WooCommerce / LatePoint / 2meet-*) live in 11 separate AddOn plugins

+* Fix: phpcs:disable file-level suppressors reduced 37 → 19 via phpcs.xml directory-level exclude-pattern rules
+* Docs: README.md + readme.txt Stable tag aligned to v3.3.1 in prior release; CHANGELOG.md backfilled for v3.1.5–v3.3.1
+
+= 3.3.1 =
+* Security: 13 admin GET state-changing operations converted to POST form (nonce-protected) — prevents nonce leakage via Referer header (CVSS 4.3)
+* Security: REST endpoints pre-filter Zone A/C fields via show_in_rest registry (CVSS 5.3)
+* Fix: phpcs:disable file-level suppressors reduced from 37 to 19 — directory-level exclusions in phpcs.xml replace broad per-file disables
+* Fix: TMDO_Crypto::is_key_derivable() public helper; wp tmdo doctor reports WARN when AUTH_KEY/SECURE_AUTH_SALT absent
+* Tests: 21 new unit tests for Diagnose, Install_Schema, Backfill_Bulk, Backfill_Unserialize, Verify_Sample phases
+
+= 3.3.0 =

+
+= 3.1.9 =
+* CI: PHPCS step in test.yml is now a blocking gate (removed || true); release.yml requires full test-gate (lint + phpcs + unit + integration) before publishing
+* Security: wp tmdo doctor adds HTTP accessibility probe for backup directory; nginx snippet surfaced when dir returns 200
+
+= 3.1.8 =
+* Security: M-AUTH-1 fix — draft/private/trash posts return 403 to anonymous users in REST get_listing; regression test added
+* Fix: TMDO_Conflict_Monitor catch block surfaces errors via TMDO_Logger::warning instead of swallowing silently
+* Docs: ADR-001 (post entity source-of-truth contract); ADR-002 (dual_write naming conflict between FSM and Entity Bridge)
+* Tests: Migration Phase unit tests for Cleanup RuntimeException guards + 4-phase lifecycle; Mode_Manager cache stubs in bootstrap
+
+= 3.1.7 =
+* Perf: Zone Cold save_blob() refactored from 2-query SELECT+INSERT/UPDATE to single INSERT...ON DUPLICATE KEY UPDATE (TMDO_DB::upsert)
+* Fix: TMDO_DB::upsert() MySQL branch migrated from deprecated VALUES() to row-alias syntax (INSERT ... AS new_vals ON DUPLICATE KEY UPDATE col = new_vals.col)

+
+= 3.1.6 =
+* Fixed: TMDO_Logger::error() call-site arity — all catch-block callers updated to 3-argument form (module, hook, message)

+* Perf: TMDO_DB::upsert() MySQL branch migrated from deprecated VALUES() to row-alias syntax (MySQL 8.0.20+ / MariaDB 10.3.3+)
+* Perf: Zone Warm set() refactored to single-query upsert; new atomic increment() method
+* Perf: Zone Cold save_blob() refactored from 2-query select+insert/update to single upsert
+* Perf: TMDO_Schema_Manager::table_exists() caches results per request to avoid repeated SHOW TABLES
+* Perf: cache_orchestrator L1 eviction O(n) → O(1); ORDER BY RAND() eliminated from verify()

+* Security: wpdo_allow_mass_column_clear filter gates delete_all (default false)
+* Security: TMDO_Crypto derived_key() returns empty string when salts absent; encrypt/decrypt short-circuit safely
+* Chore: phpunit.xml failOnWarning=true; composer.json production classmap autoload
+
+= 3.1.5 =
+* Security: Gitea release.yml rewritten — release job now requires test-gate (unit + lint) to pass first
+* Chore: capture_before_value filter default changed false to eliminate 2 extra DB queries per managed write
+
+= 3.1.4 =
+* New: User EAV ratio optimization — admin_prefs group +14 WP admin UI keys; commerce group +3 WC runtime stats; hp_user group +hp_verified
+* Perf: dev10 ratio improved 1:1.73 → 1:1.42; dev20 1:2.09 → 1:1.07; dev21 (Dokan Pro 1.8M vendors) 1:1.00
+
+= 3.1.3 =
+* Fixed: Last hardcoded inline style removed (conflict-detector.php → wpdo-list-disc class)
+* New: scripts/install-local-dev.sh rsync deployment script
+* Improved: .wpdo-mode-badge CSS transition added
+
+= 3.1.2 =
+* Fixed: ci-package.sh now uses rsync staging so ZIP top-level directory is correct 2meet-data-optimizer/
+* Fixed: phpunit-integration.xml excluded from ZIP
+
+= 3.1.1 =
+* Fixed: Version header alignment (3.1.0 → 3.1.1) and Gitea DB_PASS secret for integration tests
+
+= 3.1.0 =
+* New: scripts/ci-package.sh + .gitea/workflows/release.yml (push v* tag → auto-package + Gitea release)
+
+= 3.0.3 =
+* Fixed: wp tmdo doctor partner plugin doctor_callback invocation (call_user_func($cb) → call_user_func($cb, $tbl_raw)); eliminates WooCommerce "Too few arguments" warnings

+* Fixed: PHPCS 0 errors / 0 warnings project-wide
+
+= 3.0.0 =
+* New: HivePress family integration covering 13 official addons (core / blocks / bookings / favorites / marketplace / memberships / messages / requests / reviews / seo / social-links / statistics / tags). Auto-detect, zero overhead when HivePress absent.
+* New: 6-command CLI namespace `wp tmdo hivepress {detect,score,doctor,migrate,rollback,benchmark}`.

+* New: Comment query router (rewrites hp_message recipient lookup, hp_favorite UNIQUE check, etc. — feature flag gated).
+* New: Cron optimizer replacing HivePress hourly listing-expiry full scan (feature flag gated).
+* New: Conflict guard against legacy hp-custom-tables / hp-info-cards plugins.
+* Schema: 8 new zone/shadow tables (hot_hp_request, hot_hp_membership[_plan], hot_hp_booking, comment_hp_{message,favorite,offer}, term_hp_listing_tag).
+* Refactor: legacy `class-tmdo-hivepress.php` (242 lines) re-cast as deprecated stub delegating to new core adapter.
+* Tests: +144 unit tests + 7 integration tests; full suite 1013 tests / 2469 assertions / 0 failures.
+* Security: SQL injection / XSS / capability / ABSPATH guards all audited PASS.
+
+= 2.6.10 =
+* Fixed: 壓力測試「取消」無法中斷 — 原本 cancel() 寫入的 cancelled status 會被 in-flight run_batch() 結尾的 update_option() 覆寫回 running（race condition）
+* Added: `CANCEL_FLAG` transient — cancel() / cleanup() 設旗標；run_batch() 開頭、run_batch_realistic() 每個 user 迭代之前都檢查；read-modify-write 結尾保留 cancelled status
+* Added: 前端 cancel 按鈕點擊立即 UI 反饋（disabled + 「取消中…」），避免使用者再點一次
+
+= 2.6.9 =
+* Fixed: 啟動壓力測試 504 Gateway Timeout — `start()` 不再同步執行 batch（之前 batch=500 + realistic mode 會塞 30 分鐘以上）
+* Added: `BATCH_DEADLINE_SEC=8s` wall-clock 上限 — 每個 pump batch 跑滿 8 秒就 yield，下一次 polling 接手；遠低於 nginx 60s timeout
+* Added: PHP `set_time_limit()` 在 pump 內動態設定，確保 batch 有足夠時間完成
+* Improved: Realistic mode 預設批次提示 — 前端偵測 batch>10 時提示確認（每 user ~3 秒，batch>10 撞 deadline）
+* Improved: Admin UI 啟動後立即顯示進度卡片，不必等第一次 polling
+
+= 2.6.8 =
+* Fixed: 壓力測試進度條不更新 — 不再依賴 wp-cron 自動觸發；`get_progress()` 內建 pump 機制，每次 polling 主動推進一個 batch（用 transient lock 防併發）
+* Fixed: 啟動測試後立刻同步執行第一個 batch，使用者第一次 polling 即可看到進度
+* Fixed: `finalize()` 完成時清除殘留 cron event
+* Fixed: 兩種模式 (fast / realistic) 端到端驗證 — 進度即時推進、Hook Bus 正確攔截、密碼 PassWord2026! 可登入
+
+= 2.6.7 =
+* Added: User Entity 壓力測試 + Benchmark 工具（Tools → 2meet Data Optimizer → 壓力測試）— 設定要建立的測試使用者數，一鍵自動填滿所有 user 相關 flat tables（hot/cold/membership/activity/profile/sso/points_ledger）
+* Added: 兩種寫入模式 — `fast`（直接 bulk INSERT，~5-10K users/秒）/ `realistic`（走 wp_insert_user + Hook Bus，測試生產路徑）
+* Added: 完整 Benchmark 報告 — 寫入速率 / 批次延遲 / DB 容量（每張表 data_length + index_length）/ 6 種查詢效能（含原生 EAV baseline 對比）
+* Added: WP Cron 驅動的批次任務 + 即時進度條（2 秒 polling，顯示 users/sec、ETA、PHP peak memory）
+* Added: REST API — `/wpdo/v1/stress-test/{status|start|cancel|cleanup|benchmark}`（皆需 manage_options）
+* Added: Admin 新 Tab「壓力測試」附警告 banner，一鍵清除所有 test_* 使用者及其 flat table 資料
+
+= 2.6.6 =
+* Added: Entity Bridge tab in admin (Tools → 2meet Data Optimizer → Entity Bridge) with health cards per entity (user/term/comment) — shows mode, pipeline visualization, per-group coverage bars, shadow diff count, auto-promote status, and guided recommendation
+* Added: Async cron-driven Backfill engine (migrate_group_batch) — REST POST /entity-bridge/backfill triggers WP Cron, self-reschedules every 5 s until all EAV rows are migrated to flat table
+* Added: REST API endpoints (requires manage_options) — GET/POST /wpdo/v1/entity-bridge/health, /backfill, /promote, /demote
+* Added: TMDO_Entity_Health class — aggregates coverage pct, migration checkpoint, shadow diffs, auto-promote eligibility per entity
+* Added: wpdo-entity-bridge.js — real-time polling (5 s) during active backfill, inline promote/demote with confirmation dialogs
+* Verified: 356 unit / 181 integration / 0 failures; PHPCS 0 errors / 0 warnings
+
+= 2.6.5 =
+* Security: A-4 cleanup — removed all plaintext id_token persistence from Spoke (update_user_meta _tmso_last_id_token writes removed); logout now calls delete_user_meta to progressively clean stale values
+* Fixed: Integration test isolation — ZoneHotIntegrationTest, ZoneWarmIntegrationTest, WarmArchiveIntegrationTest, SyncBridgeIntegrationTest setUpBeforeClass() now uses DROP TABLE IF EXISTS + CREATE TABLE to guarantee clean schema even after interrupted prior runs; eliminates 65 spurious failures
+* Verified: 356 unit / 181 integration / 0 failures; PHPCS 0/0; stress-tested with pre-polluted tables
+
+= 2.6.4 =
+* Security: H-4 — AES-256-CBC encryption for Slack/Discord/Telegram webhook secrets via new TMDO_Crypto class; key derived from AUTH_KEY + SECURE_AUTH_SALT; stored as enc:v1:<base64(iv|ciphertext)>; backward-compat with existing plaintext values
+* Security: A-4 — SLO hash migration: Hub stores sha256(id_token) per user+client on token issuance; /oauth/logout accepts id_token_hash_hint with hash_equals() timing-safe comparison; Spoke prefers hash path with legacy JWT fallback
+* Admin: webhook inputs use type=password + autocomplete=new-password; empty submission preserves existing encrypted value
+
+= 2.6.3 =
+* Security: H-1/H-2 — TMDO_Snapshot_Reader::apply() verifies sha256+size before executing SQL; is_safe_name() enforces $wpdb->prefix
+* Security: H-3/M-2 — wpdo_rl_stats capped at 100 entries to prevent unbounded wp_options growth
+* Security: M-3 — nginx backup-directory protection notice in admin + README-NGINX.txt with location block
+* Security: L-1 — TMDO_DB::table() sanitizes input with sanitize_key()
+
+= 2.6.2 =
+* Added: wp tmdo benchmark --custom-tables flag benchmarks all 117 registered custom tables
+* Added: TMDO_Site_Metrics_Collector — daily 05:00 UTC cron writes 11 site-wide metrics to wpdo_site_metrics (90-day retention)
+* Added: wp tmdo site-metrics CLI command with --collect, --history, --days, --format options
+
+= 2.6.1 =
+* Added: E2E test suite T-A01–T-A20 (21 tests): Snapshots tab, Setup Wizard 5-step, Export health+snapshots
+
+= 2.6.0 =
+* Added: wp tmdo doctor integrates Custom Table Registry — partner tables shown by provider with status/row-count/doctor_callback
+* Added: wp tmdo bridge-status shows dual_write progress: flat table rows vs EAV distinct IDs, progress_%
+
+= 1.3.31 =
+* Fixed: PHP WASM / WP Playground compatibility — merged multiple PHP tags on line 604 of admin class to avoid Parse error in PHP WASM 8.3
+
+= 1.3.30 =
