Summary

  • add one Hard multi-stage benchmark from FineProofs-SFT train row 4
  • require a squarefree-kernel classification, an ordered-pair class-count identity, and a complete modular obstruction to three classes
  • independently replay all quadratic residues and all zero-padded triple sums, while accepting any valid modulus in the declared range

Selection quality

Provisional score: 87/100. This adds an equivalence-class abstraction and transversal argument followed by a finite modular certificate. It is materially different from the existing cubic-residue obstruction task, whose proof ends at a direct congruence contradiction.

Nearby candidates were rejected because they were routine telescoping or counting exercises, or lacked a stable independent verifier for the full claimed inequality.

Provenance

  • dataset: lm-provers/FineProofs-SFT
  • immutable revision: 73661e62811cf2940a0d3f82788a4f4332204c2f
  • split/row: train[4]
  • canonical row SHA-256: d221d45dfd530c3892d960f7685fd5caabcdec5079b4122731bebeab79aad52d
  • license: Apache-2.0

Validation

  • make harbor-sync
  • make harbor-check (459 passed)
  • Ruff check and format check on affected benchmark paths
  • git diff --check

The verifier reports COMPUTED only. It does not claim formal proof verification or trust the public solution text.

Reusable-tool review

No new reusable capability is justified. The repository already exposes quadratic-residue enumeration; the remaining squarefree-class and transversal steps are benchmark reasoning, and a theorem-specific wrapper would not be reusable.

The verifier checksum LABEL in the squarefree-class-independence-audit
Dockerfile drifted from sha256(verifier.py) after the recent verifier
edits, failing the Benchmark Prospective Digest Checks lane (and the
paired Benchmark Validation gate). Regenerate the label via
tools/sync_harbor_verifier_support.py --write.
