C-D16-SUPPORT4-FRAMEWORK
Primitive support-4 orbit identity + lattice + connected 4th cumulant, tau4 < 8/1000 at four primes, inventory + support-5 OPEN
In plain language
The projective method extends to four-coordinate relations, exact at four small primes, full closure and support-5 remain open.
Exact statement
Primitive support-4 orbit identity + lattice + connected 4th cumulant, tau4 < 8/1000 at four primes, inventory + support-5 OPEN
