SelectoComponents.Form.ChoiceSourceMetadata (selecto_components v0.4.8)

Projects query-contract choice-source links into form-friendly field metadata.

Query contracts expose raw fields, field_choice_bindings, and choice_sources. This module stitches those pieces together so form and UI code can ask for annotated fields instead of hand-walking the contract.

fields(contract, opts \\ [])

@spec fields(

Returns every query-contract field with choice-source metadata attached when present.

Bound fields keep their original "choice_source" scalar and receive a sibling "choice_source_metadata" map.
