FROM THE ORIGINAL BOOK GLOSSARY
Harmony Kernel is the versioned, governed, operational expression of Revenue Harmony Management’s domain knowledge. It preserves the discipline’s definitions, relationships, conditions, and boundaries so that computational systems can use that knowledge without depending on each model to reconstruct or redefine it.
It keeps domain knowledge separate from the evidence for each situation and allows that knowledge to be revised while preserving what each earlier version established.
THINK ABOUT IT
What must the system know—and never invent?
Software needs reliable definitions and limits. The Harmony Kernel is designed to hold them, so a model cannot quietly rewrite the method as it answers.
