evolution.yml

mission: "Drive ruff to zero violations on src/ — closes the evolution loop in one round, no LLM, no API key."

# No `llm:` block. No `coding_agent:` block. The roles are tiny deterministic
# Python scripts checked in under target/bots/ — they do the ruff work
# directly. The whole point is to demo the governor / observer / ledger
# stack in one terminal command at zero cost.
