  "notes": "Found by a sweep of one-block palindromic cyclic codes (Camara-Ollivier-Tillich-type group-algebra code over Z_66, arXiv:quant-ph/0502086), n = 17..200, weight <= 8. Distance ladder: 300-trial Pauli-weight RIS screen, then 2 x 20,000 trials on fresh seeds (held). Novelty unknown: not checked against codetables.de; the dedup gate found no exact, WL-equivalent or Hadamard-image board entry. Genuinely non-CSS: a and b overlap, so every generator carries Y. Corrected to d <= 11 on 2026-10-09 by @FarLab with the orbit-fold search of PR #2902 (P: 12 -> 11; see issue #2949). The over-claim was reported by @MicheldeMessieres (issue #2899).",
