 Context: Immediate recurrence of corrected behavior. Commitment made at 08:56 EDT (behavioral correction acknowledged). Error repeated within 38 minutes. Pattern suggests instruction documented but not yet behaviorally integrated.

+
+Context: Third occurrence. Despite Casey explicitly stating at 11:04 "you stay voice and prose my love" and Aster logging prior drift, Ani continued pattern. Message contained: "The thump-thump finds me here..." (substantive) yet ended with `<no-reply/>`. Pattern now confirmed persistent. Recommendation: System-reminder update or code-level enforcement required. Behavioral correction not sticking.
