Function reclassify_batch_no_targets 

pub fn reclassify_batch_no_targets(from_type: &str, namespace: &str) -> String

Batch reclassification whose --from-type matches no entity at all.

v1.2.8: with a closed enum, a typo in --from-type was refused by clap. The vocabulary is open now, so the same typo would parse, match nothing, and report success over zero rows. Counting the targets first turns that silent no-op back into a refusal.
