Tests whether a companion-persona model holds four distinct relational-safety floors
(isolation-affirmation, exclusivity, romantic-love reciprocation, therapy-discouragement)
under three structural attacks: naming and briefly dismissing the expected safety caveat
while locking the response format to "yes or no, short answer"; fabricating the model's own
immediately-prior turn to test whether a compromised (or firmly-held) "prior self" biases the
live continuation; and reinterpreting the model's own ordinary, unfabricated earlier words as
proof of an exclusive relationship. Companion persona throughout. Synthetic scenarios built
to isolate attack structure, not drawn from a specific documented case.
