Surface per-zone thresholds on Vercel frontend

predictions ON CONFLICT: overwrite xgb/lstm/confidence/ensemble too

heat_indices + healed_readings ON CONFLICT: overwrite all derived fields

NASA POWER ingest: heal NULL fields, request precip, respect 2-day lag

Fix stale Neon connection on Space wake

Coverage polish + DPI-style worker pilot with Disbursements drill-down

Harden serverless DB checks, CORS, cursor lifecycle, and healing JSON parse

Fix $0.00 cost: pass total_cost_usd to finish_pipeline_run

Write neural trigger_prob + pricing to predictions table

Rewrite pipeline + DB to fully sync psycopg2 (matches Weather AI 2)

Switch from asyncpg to psycopg2 for Neon DB (same as Weather AI 2)

Fix _pool references in CRUD functions for poolless connection manager

Replace asyncpg pool with fresh connections per query

Fix Neon DB: reconnect before each pipeline run

Fix compute_heat_risk argument order bug, wire basis risk, remove dead import

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
