The evidence trail behind the trilogy. These pages collect the cited research, published engineering and practitioner sources, and direct professional communications behind each essay.
The trilogy also uses anecdotes and analogies alongside formal sources. Those moments are craft observations, not claims to scientific weight.
Direct personal communications are listed without external links.
