  "notes": "Unmodified amm-match validate fails: Contract must be named Strategy and inherit from AMMStrategyBase. The repository contract is named VanillaStrategy; it was compiled unchanged using the official get_vanilla_bytecode_and_abi loader and used for both submission and normalizer. Explicit-seed config generation was checked field-by-field against _build_configs for seeds 0..9. Scored edges are engine edges[\"submission\"], with default 10,000 steps and baseline parameter variance; chunks contain 500 consecutive seeds. Simulation wall time includes run_batch calls only. Python venv setup initially lacked ensurepip; virtualenv resolved it."
