abstract: 'A self-contained, contract-emitting member of the agricultural analytics
  orchestra for spatial and spatio-temporal Gaussian-process regression over field
  and multi-environment-trial layouts. Fits an exact Gaussian process to spatial (and
  optionally temporal) coordinates with a choice of squared-exponential or ''Matern''
  covariance, estimating the hyperparameters by marginal-likelihood optimisation.
  Its defining feature is change of support: a prediction can be requested at a support
  different from the one observed -- a point process predicted as block (paddock-scale)
  averages, or block averages disaggregated toward points -- with the predictive variance
  propagated through the support map. Predictions abstain with a typed, machine-readable
  reason when the estimated spatial range or the data support cannot bear the requested
  resolution, so the member refuses cleanly rather than returning a confident wrong
  surface. Results are emitted as a versioned, provenance-complete object compatible
  with the orchestra ensemble-manifest contract, so a smoothed field surface composes
  directly with downstream calibration, uncertainty-quantification, causal-inference
  and decision tools. The package is released under the MIT licence and takes no heavy
  external Gaussian-process dependency: the exact solver is base R.'
