[[6,4,2]] skip done[[6,4,2]] error-detecting code
Description
Self-complementary six-qubit code with rate 2/3 that is unique for its parameters, up to equivalence \cite[Tab. III]{arxiv:quant-ph/9608006}. Concatenations of this code with itself yield the [[6^r,4^r,2^r]] level-r \textit{many…

Rationale
Audit override: [[6,4,2]] is the m=3 instance of the parametric iceberg family [[2m, 2m-2, 2]] that QEC/Stabilizer/Codes/Iceberg/N.lean defines for m ≥ 2 (PR #36, merged 2026-05-24). Previous rationale: [[6,4,2]] high-rate small CSS detection code. Direct fit; trivial proof.
