Metadata and caveats
  • generated_at_melbourne: 2026-06-21T22:15:36+10:00
  • forecast_date range: 2026-06-21 to 2026-06-22
  • source: station-aligned Open-Meteo previous_day1
  • caveat: forecast update only, no odds/trading advice
  • caveat: cutoff_status is based on configured Melbourne trigger time
  • caveat: Rows marked STALE_FORECAST_DATE are for an older forecast_date than the current expected station-local target date. They are shown for audit visibility and should not be treated as current forecasts.
  • caveat: Rounded market bucket is the model forecast aligned to the market's whole-degree precision. Polymarket outcome is the actual displayed market bin/range containing that whole-degree value.
  • caveat: Historical hit rate is research-only: exact-number matching for London/Madrid/Paris and standardized 2°F bucket simulation for Austin/NYC. Not a probability, odds, or trading signal.
  • caveat: Historical hit rate is sourced from the displayed-city settlement-standard research summary when available and shown as one long-sample backtest reference per city.
  • caveat: NYC / KLGA uses standardized settlement-standard even-lower/odd-upper 2°F range-bin research for the displayed Historical hit rate; open-ended market tails are ignored.
  • caveat: The prior NYC 57.53% bucket metric was tail-only and is no longer used for current range-bin display.
  • caveat: London / EGLC displays settlement-standard exact-number research and remains the strongest clean/near-complete exact-number city in the current long-sample summary.
  • caveat: London MAX_THROUGH_19 range-bin recompute files are retained only as historical diagnostic artifacts and are not used for the active London frontend metrics.
  • caveat: Austin / KAUS uses standardized settlement-standard even-lower/odd-upper 2°F range-bin research for the displayed Historical hit rate; open-ended market tails are ignored.
  • caveat: Denver / KBKF uses standardized settlement-standard even-lower/odd-upper 2°F range-bin research for the displayed Historical hit rate; missing observed dates remain 2025-08-30, 2025-08-31, and 2025-09-01.
  • caveat: Paris / LFPB frontend display uses Paris-Le Bourget / LFPB as the current-market settlement standard for the Historical hit rate. Older LFPG evidence is retained only as a historical/source-drift diagnostic; no station mapping or forecast definition changes are made.
  • caveat: Mexico City / MMMX is mixed-provenance near-complete settlement-standard exact-number research; the unresolved 2026-06-19 Open-Meteo source mismatch was preserved and not overwritten.
  • caveat: Madrid / LEMD uses an early forecast cutoff (MAX_THROUGH_18): the displayed Historical hit rate is computed from the station-local 00–18 forecast window. The settlement target remains the full-day observed maximum; this early cutoff was selected because the cutoff feasibility audit found minimal historical accuracy loss versus FULL_DAY_MAX. The Polymarket market does not settle at 18:00.

  • note: Core tier-1 cities are established live forecast monitors.
  • note: New watchlist cities are promoted from the new-city discovery audit and should be monitored separately before being treated as core.
