Pri	Signal	Detail	Score
95	Critical call exposure	HAPPY VALLEY FL PL (1898 priority) carries 752.8 day-equivalents of observed call exposure from 19 senior caller(s); dominant caller HIGHLAND SOUTH SIDE DITCH (143.5 day-eq). 543 season-days curtailed in the last five seasons.	51.3
85	Season call nowcast: expected curtailment	HAPPY VALLEY FL PL, 2026 season outlook: Apr 1 SWE 61% of median → severe-class year; expected curtailment ~117 of 214 season days from the basin's administration record. Dominant caller HIGHLAND SOUTH SIDE DITCH: P(call by Jun 15) = 0 over 5 comparable seasons.	67.4
79	Augmentation condition not verified	HAPPY VALLEY FL PL: the decree requires augmentation coverage for out-of-priority depletions, but NO plan membership is found. Verify coverage before relying on this supply — absent a plan, curtailment is immediate on the next call.	85.0
