A card that re-queues a command immediately after each accepted TR (live 2026-10-11: the EP BAP card re-issued the same PROVIDE LOCAL INFORMATION 1100 times) turned the background poll's FETCH/TR chain into an unbounded loop that held _CARD_LOCK forever - every card operation, a test run's start included, blocked behind it. The chain now yields: - _handle_proactive_chain aborts before the next FETCH while a test run owns the card (_TEST_RUNNING) - the pending command stays for the script - and takes max_rounds; the background poll passes _POLL_CHAIN_MAX = 10, so a chatty card cannot hold the lock. - _do_status_poll re-arms on its run skip (a heartbeat that never fetches); _timer_expired and the BIP Data-available event wait during a run; _bip_flush_channel_events stays quiet too. - _sim_resume_poll() resumes polling at every run end - the two worker bodies, their exception paths and the spawn failure. Also the TR command-details qualifier echo (TS 102 223 6.8.1: the object shall be identical to the command's): _build_tr, testscript.build_tr and the interactive _menu_send_response echoed a hardcoded 00 - harmless for the loop's qual-00 PLI, wrong for any other qualifier. The menu pendings now carry cmd_qual (parsed in the on_fetch handler). Tests: the chain bound/abort (a fake card re-queueing a command), the poll/timer guards, the resume wiring, the qualifier echo in both builders. 883 frontend + 865 Python; sw cache simple-v425.
