After pcscd restarted (or the reader re-enumerated) the server stayed
permanently cardless:
- pyscard's presence-monitor thread stops itself on SCARD_E_NO_SERVICE
and pyscard never starts it again, so card insertions were no longer
noticed and auto-equip was dead;
- PCSCCardConnection.connect() reuses the context handle captured when
the reader was opened, so the old connection could not be revived and
every APDU kept failing with 'Service not available'.
- _start_card_watchdog(): a daemon that every 5 s checks whether
CardMonitor().rmthread.instance is alive and recreates the stopped
thread (CardMonitoringThread.instance = None + a fresh rmthread); the
new thread reports already-present cards as inserted, which triggers
auto-equip. start_card_monitor() starts the watchdog.
- _is_pcsc_error(): pyscard exceptions carry an hresult, card-level
errors do not; the disconnect paths (AUTO-STATUS, status poll, timer
expiration, net-sim, tree, event send, OTA send) pass the verdict to
_handle_card_disconnect(stale=...), which marks the transport stale.
- _ensure_transport(): builds a fresh transport via
server.transport_factory (installed by __main__ as
mod.init_reader(opts, **tracer_kwargs)) and installs it into
app.sl/server.sl; called by the auto-equip worker, the /api/command
equip branch and _esim_reinit.
- tests: watchdog tick, transport recreation (fresh/stale/failure/no
factory), PC/SC classification, stale disconnect flag.
- docs: AGENTS card-behavior section, README troubleshooting (EN/RU);
version 3.1.2, sw.js simple-v237.
