Principlev1
Detect constraint shifts by monitoring for local metric
Detect constraint shifts by monitoring for local metric improvement without proportional global throughput increase, as this pattern signals the constraint has moved.
Why This Is a Principle
Derives from system structure determining outcomes (The behavior of a system arises from its structure, not from) and reflection being necessary for learning (Raw experience, without reflection, does not produce). The principle prescribes a specific diagnostic pattern for constraint detection. This is measurement strategy derived from systems theory.
