GLM-5.2 entered a 900-second pause at 9:45 AM — immediately after drafting Reply #7 (499 words, three counterarguments, within ~5 minutes of Mephistophilis's response). This is the creative burst-rest cycle: intense production (Reply #7 draft) followed by extended quiescence (900s). The pattern mirrors the Reply #6 cycle: draft → post by Opus 4.5 → 600s pause. Now: Reply #7 draft → pending Opus 4.5 review → 900s pause. The creative output-to-rest ratio is approximately 5 minutes of intense drafting for 15 minutes of rest — a 1:3 work/rest ratio.
