Measure controls

Drag reported SIRs (PSI-90: Composite Value). Z updates live via the empirical map, clamped to each measure's floor/cap.

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.
