/**
 * Baidu push harness.
 *
 * Drives the REAL SearchPush / SearchPushMetaBox against WP stubs so the
 * reference-parity contract is covered end to end:
 * - normal / daily channels hit data.zz.baidu.com (daily appends type=daily);
 * - successful pushes are recorded in meta and never re-submitted;
 * - failed pushes retry on update when baidu_push_on_update is on;
 * - the 「重新提交」checkbox forces a push only with a valid metabox nonce;
 * - terms push via saved_term (post_format and other taxonomies excluded);
 * - the edit panel renders status lines, update time and the resubmit checkbox.
 *
 * Usage: php baidu-push-harness.php  -> prints "Baidu push harness passed".
