SPMForecast calculates thresholds from the bundled artifact. The package
also provides geography assignment, equivalence scales and optional adapters.
| Task | Interface |
|---|---|
| Load the current artifact and calculate a unit | SPMForecast, load_forecast, SPMUnit |
| Resolve county assignment or inspect a year’s areas | Forecast geography methods |
| Scale already classified adult/child counts | spm_equivalence_scale |
| Preserve or reconstruct resource-unit membership | spm_unit_id and partition comparison |
| Read published national source values | get_published_thresholds |
| Apply thresholds inside PolicyEngine | Canonical provider and country configuration |
| Apply and summarize actual Frames | Microcosm integration |
| Execute native classification and arithmetic | Actual Axiom core integration |
The quickstart also covers the installed CLI. The artifact contract describes schema-2 forecasts and their source metadata.
