Certified reproduction and orbit compression
What changed
C++ producer plus two verifiers plus a provenance manifest. Orbit-level certificate for the p=53 case verified with the exact completeness equation 120 926 = 120 926.
Evidence
check 1C++ core hash matches the Python producer bit for bit (7 of 7)
check 2Completeness equation recomputed by both verifiers
check 3Streaming producer peak RAM 3.1 MB, versus 10.7 GB unstreamed
