"""Phase 2 training pipelines.

These modules require torch_geometric and a GPU. They produce checkpoints
under `gemeo/artifacts/` that the runtime modules pick up automatically.

Run order:
  1. python -m gemeo.train.primekg   — ingest PrimeKG into our schema
  2. python -m gemeo.train.hgt        — train patient HGT encoder
  3. python -m gemeo.train.txgnn      — fine-tune TxGNN for drug repurposing
  4. python -m gemeo.train.tgnn       — train trajectory TGN over snapshot chains
  5. python -m gemeo.train.neuralsurv — train survival head

All scripts can be re-run independently. See `gemeo/train/README.md`.
