…tion integrity verified Re-audited Erdős Problem #155 (Slow Growth of Maximum Sidon Subsets). Lean source (Proofs/Erdos155Problem.lean) matches meta.json: - 1 axiom (erdos_turan_upper) — encoding the Erdős–Turán/Lindström upper bound F(N) ≤ √N + N^(1/4) + 1; matches meta axiomCount: 1 - 0 sorries (matches meta sorries: 0) - 10 theorems (empty_mem_sidonSets, sidonSets_nonempty, maxSidon_achievable, maxSidon_optimal, maxSidon_monotone, maxSidon_step, increase_count_le, maxSidonSize_1, maxSidonSize_2, maxSidonSize_3) — matches theoremCount: 10 - 3 definitions (IsSidonSet, sidonSets, maxSidonSize) — matches definitionCount: 3 - 199 lines — matches lineCount: 199 - status=axiomatized / badge=axiom (Tier C) — main conjecture F(N+k) ≤ F(N)+1 remains OPEN, and the Erdős–Turán upper bound supporting the proof toolkit is honestly axiomatized Narrative checks pass: title and description explicitly mark the conjecture "Status: OPEN"; proofStrategy enumerates which results are axiomatized vs proved vs docstring-only; assumptions field declares "1 axiom: erdos_turan_upper. 0 sorries." No delegation opacity, axiom masking, inequality-as-theorem, pipeline inflation, or 0-sorries-with-hidden-imports failure modes detected. Sibling skip note: erdos-161 (also priority-top in queue) was skipped because PR #21509 already covers its cycle 4 tracker bump. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
