- register_group() accepts $args['indexes'] (name => ordered keys); indexes on
unknown keys are dropped. Kept outside the field definition, so schema
hashes are unchanged.
- Schema_Manager::ensure_group_indexes() adds missing cidx_* indexes to the
existing flat table in place; the applied definition is remembered in
tmdo_entity_indexes so later requests skip SHOW INDEX.
- Bench (1M listings, scenario 2): Entity p50 337 ms -> 278 ms with
(hp_verified, hp_price), on par with Hot (269 ms).
- Verify: core unit 656 / integration 459 green, phpcs clean

- On init:1, re-register aeav_only groups whose flat table exists and whose definition is in wpdo_registry_meta but no active plugin registers them, so their data stays readable (routing only, never DDL)
- Keys owned by a live group, or with rows in native meta (newer data written while orphaned), are left alone; the native-meta check is cached for a day
- Surface restored groups via Site Health (wpdo_orphaned_entity_groups), the admin Doctor tab, and wp wpdo doctor
- Verify: EntityRegistryRestoreTest (9), OrphanGroupRestoreTest (7); core unit 622 / integration 439, HP 141/49, WC 10/22 OK; dry-run on dev20–22 restores 16/17/4 groups, keeps hp_taxonomy hp_sort_order/hp_icon on native
