Function partition_selected_replicated_text_materialization_tasks 

pub fn partition_selected_replicated_text_materialization_tasks<G, A>(
    tasks: &[ReplicatedTextMaterializationTask],
    parameters: &ArchitectureParameterDescription,
    partition: &ArchitecturePartition<G, A>,
) -> Result<Vec<ReplicatedTextMaterializationTask>, ReplicatedTextContractError>

Completes rank projection for physical tasks selected before backend resources exist.

This attaches architecture-declared atomic companions and removes tasks not owned by the exact partition. It never reselects a source, encoding, executable format, recipe, or lowering from the architecture topology.
