Threats that exploit the receiver's detection apparatus: detection-efficiency mismatch between detectors, back-flash emission from single-photon detectors, bright-light blinding, dead-time effects, the temporal profile of detection efficiency, laser injection damaging or altering components, limits of homodyne detectors in continuous-variable systems and double-click events. Part 2's EAs 8.2 to 8.11 test the controls against them.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
