# Data policy — WP-AI-0001

All Tier-0 data are synthetic and regenerated from seeds by src/wp_ai_0001/datasets/ (generator versions are recorded in every split). Concrete split files are written under artifacts/runs/<run_id>/data/ (git-ignored) with SHA-256-derived hashes recorded in experiments/manifests/<run_id>.json.

Tier ≥ 1 model checkpoints are downloaded from the Hugging Face hub into the user's cache (not committed). Licenses: Qwen2.5 (Apache-2.0), Llama 3.2 (Llama 3.2 Community License — redistribution of derived weights to be checked before release). No restricted or personal data are used. Nothing under data/ is committed except this file.
