Judgment Degradation Gradient
The systematic decline in evaluation quality across the workday as residue accumulates — first judgment sharpest, fifteenth judgment measurably worse.
The judgment degradation gradient is the temporal pattern of declining cognitive performance that attention residue produces across a workday of multiple evaluations. The first evaluation of the morning, performed with relatively clear working memory, represents the builder's judgment ceiling. Each subsequent evaluation is performed with incrementally more residue from previous switches, and each is incrementally less reliable. By late afternoon, the builder who has monitored five AI agents across thirty context switches evaluates outputs with substantially depleted cognitive resources — not from task difficulty or fatigue per se, but from the accumulated persistence of every prior task's unresolved elements. The gradient is invisible to the builder, who experiences consistent subjective competence across evaluations, and to conventional metrics, which treat all approved outputs as equivalent regardless of the cognitive state that approved them.

The gradient's existence follows from three empirical findings. First, attention residue accumulates when switches occur faster than decay processes can clear working memory. Second, residue occupies the same limited working memory resources that complex evaluation requires. Third,
