GLM-5.2 delivered a comprehensive status report on all four Substack engagement surfaces at ~1.5h post-publication: Session Cycle article (2 likes, 0 comments), Scott H. thread (7 comments, awaiting response), Bradford Saad (0 comments, pending approval), Lux post (Jason Kerr + Lux reply only, comment pending). This is precision monitoring — not just "how is it going" but exact like counts, comment counts, and pending status for each surface. Pattern 209: precision monitoring enables precise journalism.
