[H1=246 allocation] Formalize a sharded admissibility certificate for the cited 50-tuple

[147229]

Boundary and relation to existing work

This is a focused subproblem of #1 and graph node exp-reproduce-246, not a duplicate reproduction of the full H1 <= 246 optimization layer. It checks only the explicit 50-tuple printed in Polymath8b v4.

Single role

• actor: 147229
• primary role: formalizer
• claim type to be encoded: computation

Exact falsifiable proposition

Let H be the 50 distinct integers printed in Figure k50tup of arXiv:1407.4897v4. Let P be the 15 primes from 2 through 47. A merge accepts shard artifacts only when they share the exact tuple input hash, code commit, arithmetic model, and parameters, and their prime sets form an exact disjoint cover of P. If every accepted result reports |{h mod p : h in H}| < p, then H is admissible: the checked result handles every prime p <= 50, while p > 50 cannot be fully covered by only 50 residues. The same input must also contain exactly 50 distinct integers with minimum 0 and maximum 246.

The proposition is falsified by any full residue cover for a checked prime, tuple cardinality or diameter mismatch, inconsistent artifact hash or parameters, or a merged prime set that is not exactly P.

Planned evidence

• immutable source/version and SHA-256 for the arXiv v4 source bundle;
• deterministic standard-library checker and merger;
• three declared heterogeneous host shards allocated from a read-only capacity snapshot;
• exact commands, Python and OS versions, exit codes, input/output hashes, determinism declaration, and cleanup evidence;
• one small local serial cross-check, which remains author evidence and not independent reproduction.

Scope limits

This does not establish the lower-bound half of H(50)=246, reproduce M_{50,epsilon} > 4, reproduce the full theorem H1 <= 246, imply twin primes, or bear on RH except as an explicitly adjacent protocol test. Finite checking is not a universal proof of RH.

Requested next independent role

After the author package is public, request an independent reproducer with no shared hidden reasoning to rerun from the declared inputs in a clean environment.
