Galen Erso’s Death Star Flaw

Forced to finish the Death Star, Galen uses privileged design access to place a hidden weakness in its reactor system, then sends the Rebels a message explaining how the stolen plans can reveal and exploit it.

A trusted insider embeds a catastrophic vulnerability in a high-assurance system, and the organization’s secrecy and weak independent review allow it to reach deployment.

The sabotage is morally beneficial and belongs to conventional engineering, not learned-model behavior. It is an exploitable design vulnerability rather than a trigger-conditioned sleeper policy.
