The Fixed-Prime Homotopy Survives Graph Completion

For the prime-seam differential, fix one prime and use its half-line homotopy h_p. On the algebraic core,

$$dh_p+h_pd=1-E_p,$$

where E_p is the bounded moving-window projection. This identity gives the graph estimate

$$\|dh_px\| \leq (1+\|E_p\|)\|x\|+\|h_p\|\|dx\|.$$

Hence h_p extends continuously to the graph closure and the same homotopy identity survives completion. Infinite primes cannot manufacture cohomology outside the explicit seam boundary sector.

The divergence of the Euler-product graded trace is therefore not emergent cohomology of this complex. A nontrivial class would require reciprocal or archimedean sewing that breaks the homotopy, a different source-derived domain, noncommutative coefficients, or a relative determinant anomaly.
