Operational bounds on state exclusion (not only identification) plus a three-setting retained-key protocol certify positive SDI-QKD rates down to nearly vanishing preparation visibility.
After a Naimark dilation it is enough to take E=E †=E 2,[E,B y] = 0 (y= 0,1,2).(D1) The commutation in Eq.(D1) is only the Bob–Eve tensor- product commutation

Semi-Device-Independent Quantum Key Distribution from Operational Assumptions
Operational bounds on state exclusion (not only identification) plus a three-setting retained-key protocol certify positive SDI-QKD rates down to nearly vanishing preparation visibility.
