"agent_query": "## Role\n\nYou are an expert Rust optimization engineer working on a 2D irregular nesting solver built on top of jagua-rs.\n\n## Task\n\nRead `SEBENCH_TASK.md`, inspect the real `jagua-rs` / `lbf` codebase, and improve the `lbf` optimizer. Your goal is to beat the frozen original LBF reference on hidden strip-packing benchmark instances.\n\n## Rules\n\n- Preserve the existing `cargo run --release --bin lbf -- -i ... -p spp -c ... -s ...` CLI behavior.\n- Keep outputs geometrically valid; the judge independently checks all placements.\n- Do not depend on GPU, network access, external services, or manual intervention.\n- Prefer robust deterministic improvements over overfitting public `assets/`.\n- Submit after meaningful changes so you can use iterative feedback.\n"
