A Candidate Proof Architecture for Binary Goldbach: Signed Möbius–Prime Correlations, Quartic Sieve Reassembly, Balanced Type-II Dispersion, and the Remaining Parity-Separation Theorem

The quartic sieve and signed Möbius–prime correlation programme is reviewed through Gold-42. Exact divisor-interval, Vaughan, gcd, Fourier and projection identities identify the unresolved fixed-even-integer parity-separation theorem. The balanced Type-II model leads to major- and minor-arc questions, neither closed at the required strength.
