The Prime-Square Current Is the Rank-One Seam Image
The mixed Cauchy kernel has the exact method-of-images decomposition
The second term is the unique rank-one image enforcing the Dirichlet seam at . At prime frequencies its boundary quadratic form is
Its diagonal is the prime-square current , while its off-diagonal terms retain the cross-prime seam coherence erased by scalar aggregation. For one forward--backward prime loop, sewing changes the free weight to .
This separates two repairs: the universal Dirichlet image already creates the positive mixed Green kernel; a further source-derived modular boundary repair is still required to obtain the relative BSY entropy. Any completion formula that inserts the prime-square current again without identifying these two roles risks double counting.
