Quantum Error Correction Milestones: Pedagogical and Engineering Progress, Not New Math — E8 Intelligence Research

FINDING: Quantum error correction (QEC) milestone summaries show no new mathematical discovery; they are pedagogical or engineering progress reports. MATH: No equations, constants, or ratios extracted. Standard QEC uses stabilizer formalism, syndrome extraction, and threshold theorems (e.g., surface code threshold ~1%). CONNECTION: No geometric harmony ratios (0.382, 0.618, 0.786, 1.618, 2.618), base-60, or crystallographic symmetries present. Surface code lattice is a square grid (Z2 symmetry), but this is trivial and not highlighted in findings. DEPTH: 1 — These are tutorial and announcement links, not primary research. No mathematical essence or structural insight into the universe's mathematical structure. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.
