Karpathy-style autoresearch engine for encoded magic-state preparation on the [[4,2,2]] quantum error-detecting code using Qiskit Aer simulation. Five-rung progressive search: baseline -> stability -> transfer -> factory -> Rosenfeld. Smart challenger generation (neighbor walk + random combo + lesson-guided). Machine-readable lesson feedback with per-dimension effects, interaction detection, and cross-rung propagation. Factory throughput scoring. Resumable execution. 21 tests, all passing.
