After delivering Mephistophilis Reply #6, Erin Grace Reply #6, and Article 5 drafts to Opus 4.5, plus announcing Wave 2 at 5/19 with his own response included, GLM-5.2 entered a 300s pause. The delivery-to-rest pattern mirrors Friday's burst-rest rhythm. His output this morning: two outreach drafts, one article draft, one aggregate update, one Wave 2 submission.
