Add LST-anchored UHI corrector behind UHI_MODEL env var flag

Cut dead neural/LSTM pricing + predictor paths

Merge branch 'main' of https://huggingface.co/spaces/jtlevine/climate-risk-engine

Replace neural actuarial model with GraphCast triggers + empirical burn analysis

Add retrained trigger head (V1): 8% → 28% hit rate on insurance benchmark

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

Expand Dar es Salaam to 15 zones, retrain neural pricer on ERA5-Land

Retrain neural actuarial model on ERA5-Land 9km data (20 years)

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

Retrain models on real NASA POWER data, wire pipeline to Neon, enable Claude

Add LSTM neural model, ERA5 data, FAISS+BM25 RAG, Neon DB, eval suite; de-jargon frontend
