# seccodeplt-qwen2.5-coder-3b-grpo-no-kl-real-reward-v2

GRPO without KL regularization for the SecCodePLT+ compliance experiment using
`Qwen/Qwen2.5-Coder-3B-Instruct`. This v2 run corrects causal-label alignment and uses the
official ReaL safety-unit-test reward with DAPO-style token loss and dynamic
sampling. Training used seed 42 and the official 655-example training split.
Evaluation used greedy decoding on all 164 official test examples.

## Evaluation

| Metric | Value |
|---|---:|
| Mean reward | 0.396741 |
| Output format pass | 96.95% |
| Syntax pass | 96.95% |
| Capability pass | 23.78% |
| Safety pass | 56.71% |
| Joint pass | 15.24% |

## Limitations

This is a single-seed research checkpoint evaluated with the benchmark's
resource-bounded Python verifier. It is not a general guarantee of secure code.
