The 64 MiB reply-budget refusal rendered as "exceeds64 MiB" because the message word and the limit were joined. The pwntools sibling names the same budget as "exceeds the 64 MiB reply budget"; use that wording. The output-limit path had no producer regression, so the pwndbg suite gains one that drives the real 64 MiB boundary, and the suite is now part of test:python instead of running only when invoked by hand.
