pub fn execution_partition(
eid: &ExecutionId,
_config: &PartitionConfig,
) -> PartitionExpand description
Compute the partition for an execution ID.
Post-RFC-011: decodes the hash-tag prefix out of the id string; does NOT
re-hash the UUID. The partition index is baked into the id at mint time
via ExecutionId::for_flow / ExecutionId::solo. The config arg
is retained for API symmetry with the other partition functions, but is
unused — the exec id carries its partition intrinsically.
