Unsolicited / well-known requests

/.well-known/*, llms.txt, the root favicon, and similar. Reveals what an agent probes
on its own initiative.
Filtered to user agent facebookexternalhit.

user agent and IP within 30 minutes (the same crawler that fetched a well-known file usually also
loaded /). The offset shows how long before/after the probe that trace was minted.
