Strawman Model

Imagining we adopt https://cel.dev/ and trust a Python binding for it...

class Selector(Model):
    cel_query = TextField(...)
    @property
    def compiled_cel_query(self) -> CELQuery:
        return CELQuery.parse(self.cel_query)

class ContainerVersionSelector(Model):
    selector = FK(Selector)
    container_version = FK(ContainerVersion, related_name="cv_selectors")

def get_children(container_version) -> list[PubEntVersion]:
    children = container_version.entity_list.entities
    params = ... 
    for cv_selector in container_version.cv_selectors:
        children = cv_selector.selector.compiled_cel_query.evaluate(
            context=dict(children=children, params=params)
        )
    return children

class ItemBank(Selector):
    count = IntegerField(...)
    
    def __init__(self, count):
        super().__init__(count=count, cel_query=(
            "random_shuffle(params.seed, random_choice(params.seed, children, count))"
        )
