Validate UHI_MODEL + THRESHOLD_MODE env vars; warn + fallback on typos

Simplify: reuse shared WBGT+percentile utils, batch DB writes, memoize reads

Surface per-zone thresholds on Vercel frontend

Zone-specific trigger thresholds behind THRESHOLD_MODE env var

Add LST-anchored UHI corrector behind UHI_MODEL env var flag

Cut dead neural/LSTM pricing + predictor paths

Clean up merge conflict markers in neural_actuarial.py (reference code)

Replace neural actuarial model with GraphCast triggers + empirical burn analysis

Two-tier neural triggers + funding decomposition (SEWA pilot structure)

Neural model now decides triggers AND payouts end-to-end

Compound heat triggers + settlement-specific thresholds, retrained

Chronos-Bolt encoder, retrained pricer, 14-day pipeline, sync DB

Fix critical pipeline bugs, purge flood-era code, add ERA5 to Dockerfile

Fix issues from /simplify whole-project review

Add neural actuarial pricing engine trained on real Dar es Salaam data
