[[869,169,3]] contracted affine checkerboard core, exact d = 3

Direction & hypothesis

Issue #2939 recorded a contraction sweep of the affine mod-5 checkerboard cores that was killed at 11 of 36 seeds while still descending. Its 31x31, phases (3,1), order 3 base had gone 875, 871, 869 across three seeds, and the 869 artifact was non-dominated against every entry in the `weight-8 x local-2d-bilayer` cell but never filed. This entry is that code, reached again by a fourth seed, with the base's six seeds now all run.

Construction and tooling are #2938's (research/geometric_grafts/campaign.py, @MathysRennela): rectangle completion of the affine mod-5 checkerboard grammar of notes/961-169-3.md, projection onto the encoding core, then pivot moves of degree at most 3 (XOR an own-side row into every other own-side row covering a qubit, delete the row, delete the qubit) accepted only when k is unchanged, d >= 3 holds exactly, and the stabilizer group stays one connected block. Our part is running the sweep to completion and filing what it found.

What was searched

All 36 planned chains, one process per (base, seed), on a laptop and on a Perlmutter CPU node; the sixth base of #2939's list, 34x29 at order 0, is incomplete in the constructor and yields no chain, as campaign.py itself reports. The per-base summary is recorded on issue #2939; for this base:

| seed | n reached | moves | wall time | |---:|---:|---:|---:| | 0 | 869 | 92 | #2939's run | | 1 | 871 | 90 | #2939's run | | 2 | 875 | 86 | #2939's run | | 3 | 869 | 92 | 718 s | | 4 | 873 | 88 | 710 s | | 5 | 871 | 90 | 714 s |

Two of six seeds end at 869 and none below it, so the base has converged. This entry is the seed-3 chain: base 31x31, phases (3,1), order 3; projected onto its encoding core, n = 961, k = 169; 92 accepted moves, deterministic.

Evidence trail

  • Lower bound, d >= 3: the campaign's exact test (no weight-1 or weight-2

    • logical, decided by column enumeration against the opposite checks plus rowspace membership), re-run on the final matrices.

  • Upper bound, d <= 3: weight-3 witnesses on both sides in the JSON, found

    • by the submit pipeline's RIS and re-checked by the gate.

  • Certificate: certs/869-169-3.json, level proof_log. verify/sat_certify.py

    • encodes "a nontrivial logical of weight <= 2 exists" per side; kissat 4.0.4 reports UNSAT on both and drat-trim verifies both refutations; the XOR path (pycryptosat) agrees. The entry claims confidence: exact on both sides, which the verifier accepts as an upper bound until the certificate is read.

  • Gate (verify/validate_candidate.py against main at 9de3faad): passed, no

    • exact or WL duplicate, refuter found nothing lighter, board_advancing true, dominated_by: [], cell weight-8 x local-2d-bilayer.

Where it sits

Max check weight 8 and max check diameter sqrt(20) = 4.47 after contraction, so the cell is weight-8 x local-2d-bilayer. The cell's entries with k >= 169 at d >= 3 sit at n >= 897 ([[897,173,3]], [[899,173,3]]); this one reaches k = 169 at n = 869. It dominates none of them (lower k) and none dominates it (higher n), so it is a new Pareto point. The weight-4 record at this k, [[931,169,3]], is in a different cell and is untouched.

Dead ends

  • The weight-4 x local-2d-single cell stays out of reach by this move set

    • (#2939, "What is dead"); the capped variant stalls near n = 950.

  • The 36x26 base at k = 164 reaches n = 838 and the 36x27 base at k = 170

    • reaches n = 888 in the same sweep; both are filed separately.

Tools
