Describe the bug
Inconsistent taxonomy queries being returned with --rank specified

To Reproduce
Here is an example using a while loop where it took 13 attempts to retrieve the expected metadata:

while true; do echo "attempting"; datasets summary taxonomy taxon 138948 --rank species --as-json-lines; done

This behavior does NOT occur without --rank:

while true; do echo "attempting"; datasets summary taxonomy taxon 138948 --as-json-lines; done

Steps to reproduce the behavior:
Run datasets with --rank specified. These runs were initialized without prior queries, so the initial failures are likely not due to querying the API too often.

Expected behavior
Queries should be successful and consistent. Does this have to do with the February 2026 deprecation schedule being implemented early on some servers?
