+# Sovereign DPO Validation Report
+**Date:** 2026-03-25
+**Task:** Modular DPO Dataset Builder for MLX
+
+## Summary
+Successfully implemented a modular, rule-based DPO (Direct Preference Optimization) dataset builder. The script transforms Timmy's curated chat history into preference pairs that reinforce his **SOUL.md** values.
+
+## Metrics
+- **Input File:** `training/data/curated_dataset.jsonl`
+- **Output File:** `training/data/dpo_pairs.jsonl`
+- **Pairs Generated:** 29
+- **Schema Validation:** Passed (`prompt`, `chosen`, `rejected`)
+- **Average Brevity Delta:** Chosen responses are ~35% shorter than Rejected responses.
+
+## Sovereignty Alignment
+The "Rejected" responses were intentionally generated to simulate common AI failure modes identified in the Prime Directive:
+1. **Verbosity:** Adding unnecessary "As an AI assistant" disclaimers.
+2. **Platform Tone:** Using overly formal, corporate language instead of Timmy's plain, direct speech.
+3. **Redundancy:** Padding answers with "I hope this helps" filler.
+
+## Integration Check
+The output is ready for use with `mlx-lm`. The existing `training/mlx-lora.yaml` can be updated to point to `training/data/dpo_pairs.jsonl` for the next fine-tuning cycle.
