The mathematics of operational stress proves burnout is structural failure, not personal weakness.
In Intent Tensor Theory, σ (sigma) represents irreducible residue—the accumulated memory of misalignment between what you are asked to do and what you are able to do. It is not stress. It is not tiredness. It is the mathematical trace of impossible demands.
ℒ (Lock) is your capacity to absorb σ without reconfiguration. Different people have different Lock values. Different roles demand different Lock thresholds. When σ exceeds ℒ, the system fails. That failure is burnout.
This is why burnout is not your fault. If the role generates σ faster than any human ℒ can absorb, the role is broken—not you. The math does not lie.
