Hawk06-A existence theorem

. The finite target is achieved: an initially interior logical factor has a certified quantum return through a later radiation interface, without granting the physical residual to the decoder. Ordinary decoupling, correction, and explicit access bookkeeping suffice.

The uncorrected statement that the full physical residual becomes an independently reconstructible island would not follow. The proved island is a logical reconstruction assignment. Its gravitational identification remains a separate problem.
