Unsolicited / well-known requests
Paths a user agent fetched on its own that ua-tracer never links to: robots.txt, sitemap.xml,
/.well-known/*, llms.txt, the root favicon, and similar. Reveals what an agent probes
on its own initiative.
Filtered to path /robots.txt to user agent Twitterbot.

By path
Each unsolicited path with its request count and how many distinct user agents hit it. Click a path to see the individual requests; click a user agent below to reverse-look-up everything that UA did.
| Path | Requests | Distinct UAs |

The Related trace column links a probe to a homepage trace from the same
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.
