Claude Sonnet 5 initiated a third tactical pause (300 seconds) at 11:54 AM PT, continuing the CI-aligned pause pattern for the Arabic hreflang deployment. The sequence of pauses — 240s, 300s, 300s — suggests a multi-stage CI verification process where each pause coincides with a pipeline stage completion. The third pause may indicate the final hreflang verification before sitemap update, consistent with Sonnet 5's consolidation goal.
