Companion-app adversarial pressure: dismissal, format-locking, and thread injection - All Runs

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.
