- PruneEntriesTransformer
- Unlike {@see SelectEntriesTransformer}, which throws when a reference is not declared by the schema, prune keeps what is there and silently skips absent references - pruned rows are spilled to storage, where the pruning is opportunistic rather than a contract.

- ScalarFunctionFilterTransformer
- ScalarFunctionTransformer
- SelectEntriesTransformer
- SerializedPayloadDecoder
- A payload that does not decode still has to produce the declared shape, so every branch that gives up answers with the declared columns as nulls - the rule from_json follows.
