It is one of the most mathematically rigorous and strategically important NIST domains.

🎓 How This Primer Is Used#

This overview prepares students for:

• regime_alignment.md — mapping R0–R3 structure
• student_exercises.md — short reasoning tasks
• triadic_awareness.md — connecting TF to quantum‑information metrology

It doesn’t attempt to summarize all 139+ publications — only to give a clear, respectful starting point grounded in the domain’s visible structure.
