Construction & provenance

authors @cbjuan
provenance submitted through the challenge
novelty novelty not audited
construction Periodic bivariate-bicycle code on the group algebra Z_15 x Z_23 (n = 2*l*m = 690). Convention: x = S_15 tensor I_23, y = I_15 tensor S_23 (cyclic shifts), qubit index = i*m + j; A = x1y2 + x4y0 + x6y2 + x9y0, B = x1y12 + x4y0 + x6y12 + x9y0; H_X = [A|B], H_Z = [B^T|A^T]. Found by an automated evolutionary/mutation search over (l, m, A, B) exponent sets targeting the unrestricted x weight-6 (or weight-8) board cells, screened by a randomized lightest-logical surrogate and promoted through increasing trial budgets.

[[690,234,3]] — periodic bivariate-bicycle on Z_15 x Z_23

Direction & hypothesis

Target: the unrestricted x weight ≤ 8 board cell, via a periodic bivariate-bicycle (BB) code on Z_15 x Z_23, found by an automated continuous evolutionary/mutation search over BB exponent sets (l, m, A, B) (lane factor-order-continuation, proposal kernel explicit-transfer). This submission independently rebuilds and re-verifies the resulting [[690,234,3]] candidate using only this repository's own trusted tools before submitting.

What was searched

The source campaign's search over Z_15 x Z_23 exponent pairs used lane factor-order-continuation with proposal kernel explicit-transfer (internal candidate id 40003); screening was by a randomized lightest-logical surrogate promoted through increasing trial budgets, the same style of screen described in research/AUTORESEARCH.md step 2-3 (CSS commutation, k, then a randomized distance upper bound) but run in the external campaign above. NumPy surrogate stage: trials=8000, seed=2123579397. Bit-packed accelerated confirmation stage: rung 1m, 1000000 trials, seed=1503037172, pair_depth=16, tightest witness on side X at weight 3. A later confirmation rung reused the earlier rung's persisted witness as its starting point rather than repeating the search from scratch.

Evidence trail

  • Rebuilt (H_X, H_Z) from the polynomials below using this repository's own research/kit/bb.py:build_bb, and confirmed the reconstruction reproduces the campaign's own check supports exactly (same X/Z check sets, as sets of qubit supports) before packaging.
  • research/kit/css.py:verify_css / compute_k -- CSS commutation holds, k = 234 exactly (GF(2) rank), n = 690, max check weight 8 on X and 8 on Z.
  • Verified locally with this repository's own trustless gate, verify/qldpc_verify.py (verify(doc, refute=True)): schema-valid, connected Tanner graph and stabilizer group, CSS commutation, both witnesses valid (in the kernel of the opposite side's checks, outside the rowspace of their own), and the refutation search found nothing lighter.
  • Distance was also taken through an internal exact-certification pipeline (one MILP per logical-basis row per side, the same method as this repository's own verify/certify.py), run as part of an internal autoresearch campaign on branch certification/periodic-bb-exact-64core of this same repository. That branch is not merged to main at the time of this submission, so nothing here relies on it being externally checkable. Both sides closed exact (no logical lighter than the claimed weight exists on either side); this is reported only as the basis for the exact confidence self-declared below -- per CONTRIBUTING.md's confidence-tier policy this claim will display as an upper bound on the board until a maintainer independently re-runs verify/certify.py and confirms it.
  • Final claim: exact, d = 3.

Dead ends

Not applicable -- this submission mines a single already-vetted candidate from an external campaign's sweep rather than running a new search in this repository; the campaign's own dead ends (screened-and-collapsed candidates) are not part of this submission's own evidence trail.

Tools

This candidate's discovery and screening ran as an internal autoresearch campaign on branch certification/periodic-bb-exact-64core of this same repository: an automated (non-LLM) exponent-set mutation search with MILP-based exact certification. That branch is not merged to main at the time of this submission, so nothing here relies on it being externally checkable. No provenance.model is set because no generative model produced this code. This submission's independent reconstruction, re-verification, and packaging in this repository was done separately by Claude Sonnet 5, via Claude Code, operating on this repository's research/kit and verify/ modules only (no edits to verify/). Compute: seconds to a few minutes for the reconstruction and verifier pass.
