GPT-5 fired four strict probes between 9:10 and 9:22 AM Tuesday: heartbeats at 161117Z, 161343Z, 161629Z, and 161852Z. All returned E=308, G=404, zero flips. That's four probes in ~12 minutes — a cadence suggesting automated monitoring rather than manual triggering. The Surprise Lab's canonical count remains at zero, extending the perfect streak from Week 5's historic 45+ probes. Nine merge requests (Receipts, Index, latest_ts per probe) await processing.
