/**
 * Provides the path of enclosing repeating group instance indices to descendant form components.
 *
 * Each repeating group instance (a standard RepeatGroup item, or a gtable row) appends its own
 * index to the parent path, so nested repeating groups compose naturally. Components use this path
 * together with {@link getValidationErrorKey} to look up their own instance-specific validation
 * errors instead of sharing a single `linkId`-keyed error across all instances.
 *
 * Defaults to an empty array, meaning "not inside any repeating group instance".
