  "abstract": "The effective Majorana mass is the length of a sum of three complex electron-flavour contributions. A mass-generation model determines both their sizes and how they cancel. We compare direct effective coefficients with a three-right-handed-neutrino seesaw measure at fixed Froggatt--Nielsen charges and common lepton conditions. In the normal-ordering benchmark truncated-normal ensemble, seesaw generation lowers the lightest-mass median by a factor of 3.2 while raising the effective-mass median by 13\\%. A comparison reweighted to a common lightest-mass distribution locates nearly all of the coherent mean-square increase in weaker destructive solar-pair interference. In a fixed-amplitude phase-exchange control, the response follows the conditional phase law. A second texture exposes the competing spectral effect: smaller amplitudes can outweigh weaker cancellation in the original mean square. The interference information also affects how a prediction can be used. Replacing induced phases by independent uniform phases at unchanged posterior masses and electron weights raises the benchmark direct median by 29\\%. The matrix ensemble therefore predicts a joint arrangement of amplitudes and phases whose coherent information is lost when only masses and electron-flavour weights are retained.",
