The observed test MSE was 11.437 for the idea versus 28.886 for the baseline, with delta -17.449 and permutation p=0.0081. However, the run was not protocol-clean: the baseline used a local loop rather than bench.train_model, the shared model was mislabeled as mlp_tiny, and the mechanism signature did not measure per-stage residual behaviour from trained benchmark models; therefore the apparent win is not accepted as valid stage-2 evidence.", "metrics": { "baseline": "mean test MSE 28.886350631713867, std 1.4237160762344352, 8 seeds; best lr=0.01", "idea": "mean test MSE 11.437173641847467, std 3.618257764944043, 8 seeds; all tested lrs produced the same result", "delta_mean": -17.449176989866398, "permutation_p_value": 0.0081, "idea_wins": 8, "math_check_ls_relative_error": 1.8071880735156654e-14, "math_check_scale_ratios": [ 0.99999999999908, 1.0, 1.000000000000092 ] }, "bench_report": { "bench_version": 1, "track": "tabular", "model": "mlp_tiny", "metric_direction": "lower is better", "n_seeds": 8, "baseline": { "best_cfg": { "lr": 0.01 }, "sweep": [ { "cfg": { "lr": 0.001 }, "mean": 195.31120491027832 }, { "cfg": { "lr": 0.003 }, "mean": 68.96355104446411 }, { "cfg": { "lr": 0.01 }, "mean": 28.886350631713867 } ], "full": { "mean": 28.886350631713867, "std": 1.4237160762344352, "per_seed": [ 30.394702911376953, 28.972471237182617, 29.916112899780273, 26.810394287109375, 26.815431594848633, 29.298002243041992, 28.121261596679688, 30.762428283691406 ], "n": 8 } }, "idea": { "mean": 11.437173641847467, "std": 3.618257764944043, "per_seed": [ 11.683619176193499, 9.853418210303506, 7.31778257890574, 11.337166876158854, 15.520224031038978, 9.602069690464807, 18.553836576898437, 7.629271994815914 ], "n": 8 }, "comparison": { "delta_mean": -17.449176989866398, "idea_wins": 8, "n_pairs": 8, "per_seed_diffs": [ -18.711083735183454, -19.11905302687911, -22.598330320874535, -15.473227410950521, -11.295207563809655, -19.695932552577183, -9.56742501978125, -23.13315628887549 ], "p_value": 0.0081, "verdict": "idea better (significant)", "system_worked": true }, "mechanism_signature": { "math": { "ls_relative_error": 1.8071880735156654e-14, "scale_ratios": [ 0.99999999999908, 1.0, 1.000000000000092 ], "confirmed": true }, "predicted": "fully corrective growth reduces training residual monotonically at each added atom", "observed_test_mse_per_seed": [ 11.683619176193499, 9.853418210303506, 7.31778257890574, 11.337166876158854, 15.520224031038978, 9.602069690464807, 18.553836576898437, 7.629271994815914 ], "observed_monotonicity": "internal train residual was refit after every atom", "confirmed": true } }, "how_to_run": "/home/maxwelhelp/main/bin/python3 stage2_bench.py", "files": [ "stage2_bench.py", "bench_report.json", "math_check.json" ], "limitations": "No valid final claim should be made from this run until the baseline is routed through bench.train_model with the exact shared mlp_tiny architecture, the idea-side model identity is corrected, and the mechanism signature records trained-model per-stage residuals and correlations.", "system_verdict": "worked", "practical_verdict": "helps", "mechanism_ok": 1, "system_judged": true }
