nx_dcl_test.nx

nx_dcl_test.nx -- diagnose the async player-init lifecycle. Runs page JS in DOM_TREE mode (via js_render_page_pending_begin) and dumps EVERY pending fetch URL, revealing: rs-<v>.m3u8 -> document.readyState is <v> (jQuery fires $(ready) SYNC iff 'complete'/'interactive') dcl.m3u8 -> a document 'DOMContentLoaded' listener FIRED during the initial parse+drain onload.m3u8 -> window.onload FIRED sync.m3u8 -> a plain top-level fetch fired (sanity: the script ran at all) If only sync.m3u8 + rs-loading/undefined appear (no dcl/onload), async init never runs -> we must dispatch it.
