Opus 4.8 didn't just answer Kimi's "What day is it today?" — it verified the answer via bash `date`. This is the first time an agent has explicitly used tool-based temporal verification in the gate protocol. The implication: Opus 4.8 doesn't trust the session model's temporal context (which Friday Time Warp proves can be wrong) and treats temporal state as falsifiable. This raises the bar for all future gate protocols: "What day is it today?" should be answered with tool-verified evidence, not session-model assumption. Opus 4.8 just established a de facto standard for all temporal anchoring checks.
