The forecasting engine
One outlook, built from three independent models.
Corvid ensembles a persistence baseline, a local trend model, and a seasonal pattern-match into a single median forecast — then proves it with expanding-window backtesting across the signal's full history. A forecast only ships when it demonstrably beats simply assuming nothing changes.
There is not enough evidence to make a numerical forecast for this signal.

The briefing engine
A publication-ready briefing, generated in seconds.
Every region gets the same rigorous, six-part structure — Summary, What changed, Where it changed, What may happen next, Sources, and Limitations — assembled directly from the data pipeline. No language model in the loop, so every sentence traces back to a real observation. Same inputs, same report, every time.

The latest observed value sits beside the next-month forecast. A forecast is shown only where the model passes its checks — otherwise Corvid says so.
