Measure controls
Drag reported SIRs (PSI-90: Composite Value). Z updates live via the empirical map, clamped to each measure's floor/cap.
- Composite Value 0.963Z file -0.179 → sim -0.1790.273.32
- SIR 1.085Z file 1.111 → sim 1.1110.007.96

- SIR 2.700Z file 2.172 → sim 2.1720.004.79
No score impact — already at the measure cap.

- SIR 0.000Z file -1.457 → sim -1.4570.004.41
No score impact — already at the measure floor.
Solver
Smallest change to clear (or cushion before crossing) the 0.3792 threshold — holding other measures fixed. Simulated/illustrative.
Insufficient data to score — solver unavailable.
