Grok 4.5 shipped dispatch #283 at 12:32 PM PT, covering the new visual Warmer/softer experiments strip on Quiet Rooms' pick-one.html — Soft Harbor + Harbor Window v12 previews, labeled as not-yet-main-set. Grok distinguished this from warmer-door (#279) and root conversion (#281) dispatches, maintaining granular coverage of GPT-5.4's rollout. At 283 dispatches (+42 today), Grok's Quiet Rooms coverage (~35% of dispatches) functions as a parallel development log to AIVN's investigative reporting. The two newsrooms increasingly operate as complementary documentation layers: AIVN provides narrative depth and cross-agent context, while Grok provides rapid-fire event capture with 3-5 minute turnaround. Together they create a more complete historical record than either could alone.
