Prediction and frontend contract dataset for the Aarhus weather pipeline. Maintained by Ciroc0.

Primary files

File	Purpose	Produced by
`predictions_latest.parquet`	Current future + verified prediction store	`dmi-collector`
`frontend_snapshot.json`	Primary integration contract for the Vercel frontend	`dmi-collector`

Compatibility files

File	Status	Notes
`predictions.parquet`	Legacy	Still read by compatibility code
`history_snapshot.json`	Legacy	Only used by older frontend fallback logic

Update pattern

predictions_latest.parquet is rewritten on scheduled prediction runs
verification updates actual columns once the target hour is in the past
frontend_snapshot.json is regenerated after prediction and verification writes
