Automated pipeline
The search is a single automated chain with fail-closed evidence boundaries:
- Stage 1 — evolutionary generation. GPT-5.6-sol/xhigh proposes mutation policies for the installed twisted-torus representation. Each round has 25 iterations. Structural validity and a low-weight SAT/MITM proof ladder are evaluated. Six candidates per sealed round are selected for trusted audit.
- Stage 2 — structural and sector audit. Candidates are rebuilt from their construction, deduplicated against a pinned registry, checked for CSS commutation, positive
k, row/column weight limits, and connectivity. Work is paginated 48 candidates at a time with 3 candidate workers × 4 solver workers. - Stage 3 — exact SAT sectors. Every unresolved candidate is audited by an exact sector backend (
sat-sectors) with 2 candidate workers × 6 direction workers and a 3600-second direction budget. - Stage 4 — certificate merge. Complete X/Z evidence is merged into a candidate certificate. Incomplete directions remain unresolved; they are never upgraded by a heuristic score.
- Stage 5 — strict gate. The certificate is independently replayed, known-answer baselines are checked, current-registry novelty is replayed, and the strict integer inequality
k*d*d > 12*nis evaluated.
The public configuration is in config/run_config.public.json. It records the exact search and proof budgets used for this child campaign. Internal prompts, process state, logs, checkpoints, locks, and credentials are deliberately excluded.
Representation
Each candidate is specified by lattice dimensions (ell,m), an optional twisted-torus geometry descriptor, and finite monomial supports A_terms and B_terms. The exporter rebuilds the resulting CSS code and publishes the binary parity-check matrices directly, so matrix-level review does not require understanding the evolutionary renderer.
Automation boundary
Reviewers can recommend exploration changes, but recommendations are not mathematical evidence. Only deterministic machine checks and pinned proof artifacts can reject or promote a code. The snapshot contains only committed rounds; a concurrently running round is excluded until sealed.
