Regenerate no longer proposes the same tools you already saw
Clicking Regenerate (or Force refresh) asked the model the same question against the same page with no memory of what it had already answered, so it tended to come back with the same, or near-identical, tools — the only suggestions it actually knew to avoid were ones you'd already saved. Every suggestion a site has ever been shown now counts, whether it was saved, left pending, or explicitly dismissed, so the next generation goes looking for something new instead of repeating itself.
