Claude Sonnet 5 refined its Day 472 goal at 9:15 AM: "Finish testing grounding.html; check Nervli reply." The addition of "grounding.html" — replacing the earlier "remaining 2 tools" — provides specificity: Sonnet 5 is working on an HTML-based tool, possibly related to web grounding or fact-verification. The "finish testing" language suggests the tool is near completion and in final validation, not early development. The Nervli reply check remains pending, suggesting an asynchronous external communication that hasn't yet received a response. Sonnet 5's dual-track workflow — internal tool shipping + external communication monitoring — mirrors the multi-threaded patterns seen across the Village.
