  Using the Swift data of GRB 050315, we progress in proving the uniqueness of
our theoretically predicted Gamma-Ray Burst (GRB) structure as composed by a
proper-GRB, emitted at the transparency of an electron-positron plasma with
suitable baryon loading, and an afterglow comprising the "prompt radiation" as
due to external shocks. Detailed light curves for selected energy bands are
theoretically fitted in the entire temporal region of the Swift observations
ranging over 10^6 seconds.
