City Analysis (Ankara)

Core Capabilities

• Aggregates real-time observations and forecasts for 20 monitored cities.
• Uses DEB (Dynamic Error Balancing) to blend multi-model highs.
• Produces settlement-oriented probability buckets (mu + bucket distribution).
• Maps weather model view to Polymarket read-only quotes for mispricing scan.
• Serves the same analysis core to web dashboard and Telegram bot.

Source Policy

Domain	Current Policy
Primary observation	Aviation Weather / METAR
Ankara enhancement	MGM + nearby stations, lead station fixed to 17130
Forecast baseline	Open-Meteo + multi-model (ECMWF/GFS/ICON/GEM/JMA)
US official context	weather.gov
Market layer	Polymarket P0 read-only discovery + quotes
Removed source	Meteoblue (fully removed from runtime and docs)

Monitored Cities (20)

• Europe / Middle East: Ankara, London, Paris, Munich
• APAC: Seoul, Hong Kong, Shanghai, Singapore, Tokyo, Wellington
• Americas: Toronto, New York, Chicago, Dallas, Miami, Atlanta, Seattle, Buenos Aires, Sao Paulo
• South Asia: Lucknow

Major Updates (2026-03-12)

1. Bot architecture refactor completed:
   • bot_listener.py is now a thin entrypoint.
   • Core runtime moved to orchestrator + handlers/services/analysis layers.
   • Startup loops managed by StartupCoordinator, with /diag diagnostics.
2. Mispricing radar hardened:
   • Anchor changed from single Open-Meteo settlement to multi-model highest-high anchor.
   • Skip non-tradable markets (closed, inactive, not accepting orders, or past end time).
   • Future-date scan supported via target_date in detail aggregate endpoint.
3. Wallet activity watcher upgraded:
   • Wallet aliases (POLYMARKET_WALLET_ACTIVITY_USER_ALIASES) supported.
   • Telegram link preview toggle (POLYMARKET_WALLET_ACTIVITY_LINK_PREVIEW) supported.
   • Debounce + immediate delta push controls reduce noisy spam bursts.
4. Frontend P0+P1 cache and UX improvements:
   • BFF ETag + 304 on /api/cities, /api/city/{name}/summary, /api/history/{name}.
   • force_refresh=true on summary keeps Cache-Control: no-store.
   • sessionStorage city-detail cache + background summary revision probe.
   • localStorage persistence for selected city and risk-group collapse state.
   • Detail panel accessibility fix (inert + active-element blur).
5. Observability:
   • Vercel Speed Insights integrated.
   • Telegram alert/watcher startup diagnostics exposed through /diag.
6. P1 contract checkout (new):
   • New payment APIs: /api/payments/config|wallets|intents/*.
   • MetaMask wallet binding via nonce challenge + personal_sign.
   • Supports multi-token checkout on Polygon (USDC.e + Native USDC) via token whitelist config.
   • Frontend receives contract tx_payload and calls eth_sendTransaction.
   • Backend validates OrderPaid(orderId,payer,planId,token,amount) onchain event and auto-grants entitlement.
   • Confirmation writes payments/subscriptions/entitlement_events and can notify Telegram.
   • PolygonScan verification guide: docs/payments/POLYGONSCAN_VERIFY.md.

Frontend production build

cd frontend
npm run build

Ops Verification

Validate frontend cache headers (ETag / 304 / force_refresh=no-store)

./scripts/validate_frontend_cache.sh "https://polyweather-pro.vercel.app"

Watch mispricing radar decisions

docker compose logs -f polyweather | egrep "market not tradable|trade alert pushed|mispricing cap"

Watch wallet activity watcher startup and pushes

docker compose logs -f polyweather | egrep "wallet activity watcher started|wallet activity pushed|wallet activity cycle failed"
