- pre_get_posts clears wpdo_post_clauses / _sort / _copy_route / _count_sql
before anything else: new WP_Query( array( … ) ) could preset them
- posts_orderby whitelists the copy route's direction
- Found in the 2.4 security review (Low L2; not reachable from URLs)
- Verify: PostQueryRouterCopyTest (1 new); integration 604, unit 704, phpcs 0
- PR: PR-132
- flat_first and the copy route share ties_on_post_id(): a posts.ID term
alone (optionally with a direction) reads the flat post_id; posts.ID inside
an expression a plugin added (FIELD(), IN) is left alone — inserting a
direction there made the SQL invalid and the page empty
- PCRE failures return the text given instead of '' (the query kept its
shape rather than becoming an empty request)
- Found in the 2.4 correctness review (Medium) and security review (Low L1)
- Verify: 2 new integration tests (the flat-first one runs the SQL), router suites 69 OK
- PR: PR-131
- Copy route: drop WordPress's GROUP BY when the flat row is the only join,
and read posts.ID tie-breaks as the flat post_id (own direction, once)
- Post status sync: index (post_status, post_date, post_id) replaces the
two-column idx_post_status_date (added / dropped by post-status-sync)

- posts_join joins the flat table of every routed group (a wp_core key next to a post type group no longer fails with "Unknown column")
- Flat tables are one row per post (UNIQUE post_id): remove the posts_groupby hook; skip the INNER JOIN status/date copy route for NOT EXISTS, which must match posts without a flat row
- Verify: tests/live/run.php router (9/9); qbench Q05 475 == native, no SQL error; price filter EXPLAIN has no Using temporary

- 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: when a group's post_status / post_date copies
are ready and none is NULL (one index probe per group per request), a
single-post-type search with explicit statuses and date ordering INNER
JOINs the flat table, filters the copied status, orders by the copied
post_date and skips GROUP BY. Otherwise the query keeps its old shape.
- New posts_orderby filter; bench gains an `entity+copy` variant.
- Bench (1M, with SQL_CALC_FOUND_ROWS): scenario 1 p95 3,739 -> 773 ms
(p50 670 -> 770); scenario 2 p50 356 -> 448 ms. Without found-rows the
same shape runs in 8 ms (PR-030).
