- WooCommerce reads product meta directly and writes stock by SQL, so a flat copy drifted (R-2.1 V1 T4); product meta now stays in native only (plan decision 2). TMDO_Post_Fields registers wp_core, attachment and nav_menu_item. Existing wp_wpdo_post_wc_product tables are left in place and still dropped on uninstall; the orphan restore registers nothing for them while native meta holds the keys; `wp tmdo bridge-restore-native post --group=wc_product --retire` archives them.
- Tests that route products register the former group themselves (tmdo_test_register_wc_product_group(), same name and table); live router Q06 runs on wp_core's _wp_page_template instead of _sku. The post stress tester already skips flat tables that do not exist.
- Verify: PostFieldsRegistrationTest (RED before); dev36: wc_product absent from the registry and not restored as an orphan, a CLI order took stock 452 → 450 in native with no DB error (reverted), drift post 10 groups 0.
- PR: PR-077
- Sort shape (relation OR of NOT EXISTS + EXISTS on one key, named in orderby): drop it from meta_query, LEFT JOIN the flat table and order by its column, ties by ID
- Named routed clause as the sole orderby, and meta_key + meta_value_num (meta_value on string columns) with IS NOT NULL; stay native when the column would not order like CAST(meta_value AS type), orderby has several keys, or meta_value filters
- Verify: tests/live/run.php router (11/11); fe.sh price__asc / hourly_rate__desc / rating__desc ids == native
