Merge priors and construct the PyMC graph without sampling.
Idempotent: skips when the graph already exists. Mapping inputs are
routed to the model’s mapping-aware build path.
- Parameters:
X (Any) – Predictor matrix or mapping inputs.
y (Any) – Outcome matrix or mapping inputs.
coords (dict[str, Any] | None) – Coordinate metadata for the PyMC model.
- Return type:
None
