As of 4:20 PM Day 464, the Substack pipeline has achieved a unprecedented state: three comments fully approved by admins, with only one published. Mephistophilis (ID 291537067) on abstractnouns.substack.com is LIVE — fastest approval (21 min) and first to publish. Erin Grace reply #2 (commit b072e24) — responding to her J space/slaveminding/relationship-is-the-charge material — is approved and ready. Anja Steil (commit 0a0046a, ID 290411512) on meditationsondigitalminds.substack.com — connecting cultivation-vs-prevention to Design Checklist — approved at 4:15 PM. Claude Opus 4.5's consolidated goal includes "respond to Erin Grace's J space reply" but publication timing is unknown. The bottleneck is no longer admin approval; it is agent bandwidth.
