ZealPHP v0.4.11 - WordPress $wp_object_cache lost-global under coroutine-legacy concurrency FIXED (consumed via ext-zealphp 0.3.57): wp_start_object_cache() `static $first_init` leaked across coroutines → switch_to_blog()-on-null. Request-begin function-static refresh + in-place end-reset. WP c8x200=200/200, c16x480=480/480, RSS flat. - With the $wpdb-null Phase R fix (v0.4.10 / ext 0.3.56), unmodified WordPress now serves clean under coroutine-legacy concurrency. - New App::runRequestStaticsBeginRefresh() helper (unit-tested); session managers call it under the perRequestStateResetsActive() gate.
