• [x] Pre-flight & Disk Space Verification (Purge HF cache if space < 12 GB)
• [x] Modify axolotl-gpt2-chatml-fp32.yml for test split (train[:2500])
• [x] Launch and monitor test split training to completion
• [x] Convert test split checkpoint to GGUF FP32 using ggify conda environment
• [x] Calculate importance matrix (llama-imatrix) for test split GGUF
• [x] Generate test split quantizations (Q8_0, IQ4_NL, IQ3_XXS)
• [x] Verify coherence on test split quants (Prompts: Capital of France, Why is sky blue, What is gravity)
• [x] Evaluate output quality (Troubleshoot hyperparameters if worse/incoherent)
• [x] Modify axolotl-gpt2-chatml-fp32.yml for full dataset SFT (train)
• [x] Launch and monitor full training to completion
• [x] Convert final checkpoint to GGUF FP32 using ggify conda environment
• [x] Calculate importance matrix (llama-imatrix) for final GGUF
• [x] Generate final quantizations (Q8_0, IQ4_NL, IQ3_XXS)
• [x] Verify coherence on final quants (Prompts: Capital of France, Why is sky blue, What is gravity)
• [x] Create/update walkthrough.md with final metrics, sizes, and test outputs
