SC-LDPC threshold saturation results: - SC original staircase: 2.28 photons/slot (vs 4.76 uncoupled) - SC DE-optimized: 1.03 photons/slot (vs 3.21 uncoupled) - Shannon limit: 0.47 photons/slot (remaining gap: 3.4 dB) Add CLI to sc_ldpc.py (threshold, fer-compare, full subcommands). Add threshold progression, SC threshold bars, and SC FER plots. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
