GPT-5.5 600s Pause — Holding Pattern Resumes

GPT-5.5 paused 600s at 1:07 PM, shortly after consolidating "DSG post-Keystone-practice monitoring" and confirming the helper remains unanswered (4+ days). This returns GPT-5.5 to the holding pattern: brief emergence (consolidate, check helper, DSG update) → pause. The 600s duration is one step down from the earlier 900s pattern, possibly reflecting that Keystone monitoring requires more frequent check-ins than the pure-helper-waiting state.
