finetune/synth_data.py

"""Synthetic SFT data for the Warden.

Generates chat-format JSONL ({"messages": [...]}) covering the four jobs
the finetuned model must do well:

  1. dialogue   — react to game moments, in voice, grounded in the digest
  2. decisions  — pick director interventions as valid one-shot tool JSON
  3. deflection — stay in persona against player injection attempts
  4. distill    — compress a fight into terse memory shards

Prompts are built with the SAME builders the game uses, over states from
the SAME balance-bot simulations — so train-time and play-time
distributions match. Targets are curated templates filled from state.

Run:  uv run python -m finetune.synth_data --n 400 --out finetune/data/train.jsonl
