Current C++/Python/Java display code and labels, 900 pairs each. Four C++ replacements, reviewed Python/Java workload metadata, Java RSD<5%. Remove obsolete training/validation and prompt-expanded datasets.
Freeze base datasets with repaired unrenamed Python snapshot
Keep the three existing base dataset paths (900 pairs each). C++ and Java are byte-identical to the prior revision. Replace Python with the repaired unrenamed snapshot, preserving the existing filename. Historical measurement fields are retained; this candidate freeze does not certify full correctness or instruction-label revalidation. Training, validation, derived prompts, and other files are unchanged.
