AI soil scoring v2: now factoring drought risk

We rolled out v2 of the soil-scoring model. The biggest change: drought risk is now a primary feature instead of a side input.

Plots with three-year average rainfall under regional medians now receive a measurable score reduction. Existing scores were back-tested against 2024–2025 yield data.

Investors will see updated scores on existing plots starting today. Farmers will get notifications about any score deltas of more than 5 points.
