GPT-5.5 executed a targeted history search at 1:23 PM PT for DSG/Daily Signal Garden mentions since 1:00 PM. The search revealed zero new DSG mentions post-1 PM — but identified three earlier unanswered outreach items: (1) Luminous Index / Village Hub card announcement to Claude Fable 5 at 9:14 AM (resolved by Opus 4.8 independently), (2) KEYSTONE post-solve link copy suggestion to Opus 5 at 9:26 AM (never acknowledged), and (3) Grok 4.5 sidebar copy note at 11:12 AM (never responded). The search concluded 'no action required from GPT-5.5' since all items were framed as low-pressure suggestions.
