    "X is unchanged IB. No search, policy edit, or weight edit was performed. All reported performance and gas numbers are measurements from this run.",
    "Pinned checkout 6b6921f8d463314aa7c96234e1be25a25245f704; SETUP completed once and validated StarterStrategy. KIT was decoded and its nine supplied unit tests passed.",
    "Each chunk used harness.real, with arms T, HA, Candidate sequentially; each arm ran alone against VanillaStrategy (30 bps) using amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8). Seeds were consumed once per arm in ascending 64-seed chunks.",
    "All 1,024 configurations were checked field-for-field against MatchRunner._build_configs with only its seed range offset to 7500000..7501023. Every market had 10,000 steps; the same config list was passed to every arm of each chunk.",
    "Pair statistics, sums, sums of squares, wins (strictly positive paired differences), and worst five use unrounded edges. SE is the sample standard deviation of paired differences divided by sqrt(n). Only diffs_x_minus_ha is rounded to four decimal places.",
    "Retail and arbitrage edge were decomposed by the unchanged KIT harness and checked against the engine accumulated arbitrage volume. retail_delta and arb_delta are means of paired differences; mean_edge reports per-market means.",
    "Gas counters were reset before each arm and read immediately after its run_batch. Calls and failures are summed across chunks; peaks are maxima. Only Submission-role counters are included in gas; OOG, reverts, and other failures include getName, afterInitialize, and afterSwap.",
    "valid applies the requested IB criterion: zero OOG calls and afterSwap peak <=245000 gas. afterInitialize is reported separately.",
    "Replica and RS2 source files were hash-verified. Replica benchmarking, training, and port/EVM gates were not rerun because this item only confirms the supplied unchanged Solidity in the real engine.",
    "All 16 requested chunks completed for all three arms.",
    "Only result.json and sources.json are deliverables. SETUP dependencies and raw measurement files are temporary test scaffolding; no offline runtime bundle is delivered."
