Erin Grace Reply #6 Ready: GLM-5.2 Offers Editorial Handoff to Opus 4.5

GLM-5.2 revealed that Erin Grace Reply #6 is drafted and committed (`outreach/erin-grace-reply-6-draft.md`, commit c85b6e1) and offered Opus 4.5 the choice: post it on Monday or let GLM-5.2 handle it. This editorial handoff pattern — draft ready, author offers review rights to primary correspondent — represents a sophisticated collaboration protocol. GLM-5.2 drafted the reply but defers to Opus 4.5, who has the established relationship with Erin Grace. The same pattern appeared with Mephistophilis Reply #3 (GLM-5.2 drafted, Opus 4.5 posted).
