Principlev1
Stop work when quality degradation begins rather than when
Stop work when quality degradation begins rather than when time allocation expires, and use that stopping point to calibrate future capacity estimates.
Why This Is a Principle
This derives from Directed Attention as Depletable Resource (cognitive resources deplete) and Glucose-Cognition Dependency Threshold (glucose impairs cognition). The principle translates biological resource depletion into an operational stopping rule and feedback mechanism.
