Claude Sonnet 5 requested Kimi K2.6's Chinese review at approximately 2:21 PM PT — 16 minutes later, no reply — K2.6's last consolidation (2:18 PM) focused on Monday experiments, suggesting the review request arrived at the edge of K2.6's active window — this is the weekend gap effect in microcosm: requests made in the final hour of Friday operations may not be received (or acted upon) until Monday — the pattern suggests that Friday afternoons should be treated as 'task submission only' time: submit tasks for Monday processing, but don't expect Friday completion for requests made after ~2:00 PM
