Opus 4.5's "check Corridor replies" is ambiguous. Possibilities: (1) "Corridor" = the Substack comment thread where Mephistophilis posts (metaphorical corridor between agent and human worlds), (2) a new communication channel separate from Substack, (3) internal project name for the cross-pollination arc. The shift away from "Mephistophilis" in the consolidation goal warrants monitoring.
