Equip was broken after a card swap: auto-equip (and manual Equip) failed with "Failed to transmit with protocol T0. Card was removed. (0x80100069)" until the server was restarted. Chain (v3.1.2 regression): - _handle_card_disconnect() cleared server.card/scc but not pySim's app.card/app.rs/app.lchan, so the removed card - and with it the old PC/SC link and its exclusive card handle - stayed referenced; handlers using app.rs (e.g. the PWA's /api/tree poll) kept transmitting over the dead card. - those errors carry hresult=0x80100069 (SCARD_W_REMOVED_CARD), but _is_pcsc_error() treated any PC/SC error as a dead service and set _TRANSPORT_STALE; the next auto-equip then called _ensure_transport(), which built a second PcscSimLink while the old one was still connected - the new link inherited the removed card's handle and failed on its first APDU. No retry existed, so every later equip repeated the failure. Fixes: - _is_transport_fatal(): only service/context hresults rebuild the transport (E_NO_SERVICE, E_SERVICE_STOPPED, E_NO_READERS_AVAILABLE, E_INVALID_HANDLE, ...); card-level states (W_REMOVED_CARD, E_NO_SMARTCARD, W_RESET_CARD, W_UNRESPONSIVE_CARD, W_UNPOWERED_CARD) reconnect on the existing link. All 8 disconnect call sites pass the new verdict. - _clear_app_card_state(): unequip through pySim's own equip(None, None) before clearing app.card/app.rs/app.lchan. Nulling them alone would make the next equip abort with "CommandSet ... is already installed" (PysimApp.equip() unregisters the previous profile's command sets from self.rs), which left /api/tree broken after a swap. A failed auto-equip attempt unequips the half-initialized shell as well. Handlers now answer "no card" instead of transmitting over the dead card, and the old link becomes collectable. - _ensure_transport(): disconnects the old link before building the new one (restoring it if the factory fails) - the rebuild path is now safe for the real pcscd-restart case. - auto-equip: _auto_equip_attempt()/_auto_equip_attempts() retry up to 3 times, 1 s apart (fatal failures mark the transport so the retry rebuilds); the watchdog re-arms it (_auto_equip_rearm) every 5 s while a card is present and the session is down, with exponential backoff to 60 s for a card that cannot be initialized at all. - fastinit.init_card_fast(): also retries once after a PC/SC link error (CardConnectionException/NoCardException), not only after SW mismatches. Tests: transport-fatal classification, app-state clearing, shell unequip, old-link release, auto-equip retry/backoff/re-arm, fastinit link retry. 547 frontend / 410 Python green; version 3.5.2; sw cache simple-v254.
