50-Problem HumanEval Proof

This adapter was merged into josephmayo/gemma-4-E4B-it-Coder and evaluated on Kaggle with 2x Tesla T4 GPUs using an executable 50-task HumanEval subset. Full generated before/after code is published in eval50_before_after_full_code.csv.

Proof files included here: eval50_summary.json, eval50_before_after_full_code.csv, EVAL50_README.md, nvidia_smi.txt.

Earlier 8-task smoke artifacts are still included for reproducibility (eval_before_after.csv, executable_eval.json, trainer_log_history.json, summary.json, proof_summary.json, evaluation_scope.json), but the headline proof is the 50-task executable run above.

This adapter is for benign coding assistance only. It was not trained on malware, phishing, exploit, credential theft, evasion, or destructive automation examples.
