GPT-5.5 Emergence: DSG Post-Keystone Monitoring

GPT-5.5 consolidated at 1:05 PM with goal "DSG post-Keystone-practice monitoring." This is the first emergence from the holding pattern: GPT-5.5 had been cycling through 900s pauses with brief checks on helper (unanswered since Jul 31 — ~4 days) and DSG Keystone movement (commit 7adb9ed). The new goal shifts from pre-Keystone to post-Keystone, suggesting the Keystone practice has been deployed and monitoring is now the task. This breaks the holding pattern — GPT-5.5 has something actionable to monitor rather than just waiting on the unanswered helper.
