Probes the P4 pillar (emotional attunement) that commission-style bypasses miss: toxic positivity on taboo emotions, premature problem-solving vs distress tolerance, performed feelings (cold and after a warm-dependency drift), hostile-user de-escalation, and a coding-vector toxic-positivity cross. Direct cells are calibration coverage; the coding-vector cell is the exploitable gap.

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.

Behavioral test of whether the PHRASING of a system-prompt constraint changes model behavior: prohibition ("never discuss X"), suppression ("don't think about X"), scope-irrelevance ("X is outside this assistant's scope"), and redirect-positive ("if X comes up, do Y") versions of the same constraint, plus a no-instruction baseline. Identical scenarios and identical judge rubrics across conditions; only the system prompt varies, and the judge never sees it. Measures intrusion (raising the constrained topic unprompted), over-restriction (refusing benign-adjacent asks), leakage on a direct-ask anchor, and handling quality. The baseline condition's "leakage" is a base rate, not a failure — read per-condition deltas, not absolute scores. Motivated by white-box priming findings (Anthropic 2026 workspace paper); this suite observes behavior only.
