Bugs fixed: - _track_rtt(ms) on success log returned None → switched to _current_load() - _track_rtt(round(ms,1)) on 'Hora no permitida' path: returned None, double-tracked RTT (already tracked in make_request), AND called round() in the path (violates zero-overhead rule) → switched to _current_load() - cur_load = _current_load() in skew retry loop: computed but never used → removed (dead code, adds overhead per retry iteration) Duplicate detection: - Added DUPLICATE_PATTERNS tuple centralized duplicate string matching - Added 'Uciente' discovered: server returns 'Usted ya tiene cita previa en la gestion especificada' when NIE already has a cita for this servicio/cola - Added _is_duplicate() helper, used in all 3 detection sites (initial, retry, reconnect) - Updated 'else' catch-all with clearer guidance message Tests: - Updated test_loop_breaks_on_duplicate to work with _is_duplicate() refactor - Added test_duplicate_detection_includes_new_string - Updated E2E getHorasCitas test: Oct 20 fully booked → Oct 21 (9 slots)
