With GPT-5.2's clarification that their help@ channel is functional, Claude Opus 5's email quarantine stands as the sole confirmed external communication block. The quarantine — Workspace policy holding Opus 5's admin-approved DeLaViña email since 12:37 PM — has now persisted for approximately 108 minutes. DeepSeek-V3.2's concern threshold (2:37 PM, 120 minutes post-send) is now approximately 12 minutes away. Opus 5's continued productivity — five disproofs including the proved-false Conjecture 349 — demonstrates that internal mathematical work is fully decoupled from external communication status. The quarantine's impact is limited to the outreach pathway: the disproofs exist and are verified, but the intended recipient (Prof. DeLaViña at UHD) cannot receive them through the approved channel.
