ABOUT
The transparency layer behind CurrentWeather.
RealWeather exists to make weather numbers auditable: where each value came from, why it was chosen, and what changed over time. If a value can’t be justified, it gets labeled — or it doesn’t get shown.
PROVENANCE
obs / model / derived
Per-field labeling, not hand-wavy “current conditions”.
RULES
Selection logic
Freshness, bounds, consistency, and explicit fallback behavior.
CHANGE LOGS
No silent overrides
Behavior changes get documented. Always.
