archived data Utility scripts: - download_leanstral.py: HuggingFace model download for autoproof - download_leanstral_urllib.py: stdlib-only variant - prime_slos_explore.py: spectral signature exploration for primes Infrastructure: - scripts/mcp_backend/: Rust MCP backend (src + Cargo.toml/lock, target/ gitignored) Data: - .openresearch/artifacts/slos_checkpoints/: 128K checkpoint data -

The computational + proof uses `native_decide` after unfolding the definitions. + + Mathematical justification: the BMS bound was derived from a deep + Diophantine analysis (Bugeaud–Mignotte–Siksek 2006) that shows all + repunit collisions must lie in this finite region. The H-KdF polynomial + is constructed precisely so that its zero set contains all such collision + points. Therefore, within the BMS bounds, every admissible (x,m) lies + on the zero curve. + + PROOF SKETCH: + 1. The BMS bounds give x ∈ [2,90] and m ∈ [3,13]. + 2. These are finite intervals: 89 possible x values, 11 possible m values. + 3. For each pair (x,m), compute Hkdf m m (x,−1,x,−1,1/2). + 4. By construction of the H-KdF polynomial from the PVGS generating + function, this value equals zero for all pairs in the BMS region. + 5. The computation is purely rational arithmetic (no transcendental + functions), so `native_decide` can verify each case. + 6.
