Direction of better
Higher values are better. Used to rank candidate towns/properties; higher score = stronger fit.
Unit
Values are reported in count.
Default weight in Safety composite
15% of the Safety composite by default. Users can override this weight in their intake; the displayed score reflects the user's chosen weighting, never a fixed default.

JSON-LD example
Every value emitted by ValiFit (in /api/v1, MCP responses, on-page JSON-LD) carries a propertyID set to this metric_id, so AI clients can resolve it back here in one round-trip.
