  "verdict": "Implemented PPMI-gated BCM SDR preprocessing with the same mlp_tiny supervised architecture as baseline on the structurally matched cycle_topology_graph task. Across 8 paired seeds, idea error was 0.476875 versus baseline 0.508750, delta=-0.031875, permutation p=0.0169, so the harness criterion for a significant win was met. The mechanism signature was not confirmed because all observed gates were approximately 1, so this is task-level evidence rather than confirmation of PPMI suppression.",

Node2vec, GraphSAGE, link prediction, corruption robustness, large-scale memory, wall-clock scaling, and Count-Min Sketch streaming were not tested. The signature confirmed field is false because the observed pair gates were all approximately 1.",
