4 · What happens under stressempirical administration replay + season nowcast

median year: 81% seasonal reliability
severe drought (2002-class): 16% seasonal reliability
2026 season nowcast: Apr 1 SWE 61% of median → severe-class year
call timing: P(call by Jun 15) = 0.33 · P(any call) = 0.33 · expected first call ~day 155
method: empirical replay of observed administration by condition class — modeled, not observed

7 · Verify before closingthe transaction-specific evidence checklist

resolve right ownership: best evidence is probable — county deed research + company records required
verify diligence status: conditional components require a current diligence finding
confirm administration exposure: 6 observed senior caller(s); verify current call status with the division office
professional review: this report is data intelligence, not a legal or engineering opinion
