Returns the selected immutable version and row count, or an explicit unavailable reason. Does not acquire data or charge. ## OpenAPI ````yaml /openapi.json post /api/v1/data/resolve openapi: 3.1.0 info: title: Verdant Climate Data API version: 1.0.0 description: >- Versioned climate data with preserved meaning. Discover → inspect → resolve → query. Small published-data queries return values directly, with explicit units, spatial support, missingness and provenance. Public demo endpoints require no credentials.
