- posts_request only drops SQL_CALC_FOUND_ROWS, but WordPress then treated the request as filtered and selected full post rows through a temporary table; split_the_query now keeps the ID-first split for routed searches when nothing else changed the request, and posts_request_ids drops SQL_CALC_FOUND_ROWS from the split ID query
- Verify: tests/live/run.php router (12/12, IDs-first request, found_posts == native); dev36 fe.sh price 589→340 ms, price__asc 961→427 ms, rating__desc 1724→872 ms, hourly_rate__desc 855→884 ms (was 1206)

- Leave the query to WordPress on OR, nested groups with registered keys, several post types, orderby on a named routed clause, and compare/type pairs whose flat-column semantics differ from native (untyped numeric ranges, CHAR on decimals, NUMERIC on text)
- Wrap LIKE values as %esc_like%; hook pre_get_posts at priority 1000 so plugin clauses (HivePress) are seen
- Verify: wp eval-file tests/live/run.php router (7/7); qbench Q04/Q06/Q08/Q14/Q16 == native on dev36

- TMDO_Post_Query_Router drops SQL_CALC_FOUND_ROWS from routed searches
(posts_request) and answers found_posts_query from a COUNT(*) of the
same query, cached in the object cache under posts' last_changed.
- Hook Bus flat post writes and deletes move posts' last_changed: in
aeav_only they skip update_metadata()'s own hooks, so query caches
would otherwise outlive the write.
- Bench (1M): cached page 8 ms (was 694 / 363 ms for scenarios 1 / 2);
after invalidation 8 ms + COUNT 608 / 344 ms, on par with before.
- REST X-WP-Total COUNT is on the frozen Hot zone path (ADR-003): not
changed.
- Verify: core unit 659 / integration 475, HP 142/49, WC 10/22 green,
phpcs clean
