# Gemma-4-E4B-Sol-Traces-v4

**Targeted routing-repair continuation** from v3. Continuation-trained on 125 mined trajectories (SWE-bench, synthetic, bash history, GitHub commits) to fix `run_command`, `search_code`, and `apply_patch` tool selection.

## Training

| Training type | Continuation (100 steps) |
| Dataset | 125 train / 15 val / 17 test |
| Sources | SWE-bench (50), synthetic (50), bash history (55), GitHub (2) |
| Tool schema | 6 tools (search_code, run_command, apply_patch, read_file, list_files, write_file) |
| Learning rate | 3e-5, cosine, 3% warmup |
| Batch | 1 × 8 grad accum |
| Runtime | 12 min on H100 |
| Training loss | 0.093 |
| Eval loss | 0.671 |
| Cost | ~$0.80 |
