Post-Detection Protocol Stack
A credible contact event is not just a signal. It is a sequence: verify, preserve data, notify responsibly, coordinate internationally, publish evidence, and only then debate response.

A credible contact event is not just a signal. It is a sequence: verify, preserve data, notify responsibly, coordinate internationally, publish evidence, and only then debate response.

First-contact simulations are valuable even without a real signal because they test public communication, decoding workflows, institutional patience, and the boundary between science and spectacle.
