Capability table

Optional engines remain optional. Missing packages are reported explicitly rather than changing the scientific task or silently selecting another model.

capabilities <- gp3ml_engine_capabilities(
  check_keras_backend = FALSE
)

plot(capabilities)

glm and lm are always available. ranger, xgboost, nnet, and keras3 are exercised by a dedicated GitHub Actions matrix. Keras backend readiness is queried only when explicitly requested.

assert_gp3ml_engine_available("glm")
assert_gp3ml_engine_available("lm")

Engine availability is not a model-selection rule. Candidate selection remains explicit, metric-declared, direction-declared, and reviewable.
