# PolyWeather Pro

Production weather-intelligence stack for temperature settlement markets.

Official dashboard: [polyweather-pro.vercel.app](https://polyweather-pro.vercel.app/)

## What This Project Does

- Aggregates weather observations and forecasts for monitored cities.
- Blends multi-model forecasts with DEB (Dynamic Error Balancing).
- Computes settlement-oriented probability buckets (mu-centered distribution).
- Maps model view to Polymarket read-only market data for mispricing/risk scan.
- Delivers the same core logic to web dashboard and Telegram bot.

## Current Source Policy

| Domain              | Source Policy                                        |
| :------------------ | :--------------------------------------------------- |
| Primary observation | Aviation Weather / METAR                             |
| Ankara enhancement  | MGM + nearby stations, lead station fixed to `17130` |
| Forecast baseline   | Open-Meteo                                           |
| US official context | weather.gov                                          |
| Market layer        | Polymarket P0 read-only discovery + quotes           |
| Removed source      | Meteoblue (fully removed from code and docs)         |

## Recent Changes (2026-03-11)

- Removed all Meteoblue API integration and references.
- Fixed market top-bucket rendering path by deduplicating repeated temperature buckets.
- Added frontend fallback guard when market top buckets collapse to low-quality duplicates.
- Fixed detail panel accessibility issue (`aria-hidden` focus conflict) using `inert` + active-element blur.
- Added Vercel Speed Insights integration in `frontend/app/layout.tsx`.

## Repositories and Runtime Paths

- Frontend: `frontend/` (Next.js App Router)
- Backend API: `web/app.py` and `src/`
