  Using the Swift data of GRB 050315, we progress on the uniqueness of our
theoretically predicted Gamma-Ray Burst (GRB) structure as composed by a
proper-GRB (P-GRB), emitted at the transparency of an electron-positron plasma
with suitable baryon loading, and an afterglow comprising the so called "prompt
emission" as due to external shocks. Thanks to the Swift observations, the
P-GRB is identified and for the first time we can theoretically fit detailed
light curves for selected energy bands on a continuous time scale ranging over
10^6 seconds. The theoretically predicted instantaneous spectral distribution
over the entire afterglow is presented, confirming a clear hard-to-soft
behavior encompassing, continuously, the "prompt emission" all the way to the
latest phases of the afterglow.
