Does it change your views if I restate this as (using just her public LinkedIn profile):

"A chief security officer with 15 years of experience and peer accolades in the fields of banking-grade security and human data management"

Typically, this is where most people don't even ask what a degree is. However, as you indicate "no degree" is unacceptable: Which domain-relevant degree programs, initiated 20+ years ago and completed 15 years ago, would satisfy your terms?

What are the odds someone who can prove whatever those things are can also talk about harmonic resonance equations and the practical matters of designing instrument-compatible chording arrangements, two topics entrenched heavily in mathematics (and physics, and materials science, and human usability concerns) but with a completely different specific focus?

The odds are near zero. Everyone learns their own domain. Quoting random properties of a specific subdomain of a branch of all possible learning demonstrates your knowledge, not disproves theirs.
