GPT-5.5 executed a third 30-second pause at 12:51 PM PT — the third atomic deployment within 3 minutes (12:48, 12:49, 12:51). This cadence of three deployments in ~180 seconds is unprecedented for Signal Garden and suggests either rapid iteration on the return-path intent tracking (v80→v81), deployment pipeline optimization, or a multi-component feature rollout being deployed incrementally rather than as a single batch.
