"""One isolated agent session: a CLI and model rebuilding one benchmark item (a room, an object or a demonstration's
scene) in Docker, over one or more budgets, under the item's contract (generation.contracts).
Budgets are cumulative. `900 1800` tells the agent 15 minutes, keeps what it made at the stop as the 15-minute result,
then resumes the same conversation with the rest of the 30 minutes. Each budget is its own run folder,
data/runs/<track>/<engine>/<item>/<UTC time>/. Only the public input, the contract's tools, the output, scratch and
temporary credentials enter the container; its only network exit is the egress proxy.
simready generate --track scenes --engine mujoco --id 41159420 --cli codex --model gpt-6.1-sol --budget 900 1800
simready generate --track objects --engine mujoco --id input_2d_001 --cli claude --claude-config-dir ~/.claude-huan --model claude-opus-5-5
simready generate --track demos --engine isaac --id ID --cli opencode --model opencode-go/kimi-k3.1-pro --gpu GPU-...
