An Executable-Gate Multi-Agent Research Organization: Artifact, Case Study, and a Pre-Registered Gate-Calibration Study

A domain-agnostic, gate-based multi-agent research organization (executable per-role gates, adversarial pairing, kill authority), released together with a limitations-forward case study of its first documented run and a pre-registered, blinded, seeded calibration study measuring per-gate sensitivity, specificity, and attribution accuracy, including an ablation of the round-1 rejection prior.
