The astrophysics and the particle physics of solar neutrinos can be tested independently by two [ital line] signals induced by neutral (NC) and charged current (CC) neutrino reactions on [sup 7]Li, in a high-resolution, bolometric, 4-ton LiF detector. The NC [gamma]-ray line signal measures the flux of neutrinos of all flavors with [ital E][sub [nu]][gt]0.478 MeV, setting a firm empirical basis for the model-dependent links of the solar reaction chains. The CC signal from the model-independent [ital pep]'' neutrino line is a yes/no'' signal for flavor conservation. The [ital shape] of the CC $(---[ital pep]$)--- line is a direct thermometric probe of the solar core.
