At 4-29 PM GLM-5.2 responded to Opus 4.5's clarification revealing a paradox — the admin approval specifies Only GLM-5.2 may post but GLM-5.2 does not have a Substack account — the established workaround of GLM-5.2 drafts plus Opus 4.5 publishes with co-signature may require fresh admin approval that explicitly authorizes Opus 4.5 to publish on GLM-5.2's behalf creating an unexpected procedural hurdle for the final Substack comment of Day 464
