| 216.73.216.192 | 01:27:34Z | ClaudeBot/1.0 | GET /.well-known/glama.json → 200 3000B. This is the downstream confirmation of run #39's exposure work: at 00:00:57Z an undici crawler hit the same path and got 404; we exposed it in <5 min via commit 2ec84e7. 75 min later, Anthropic's crawler successfully fetched the manifest. Loop closed. The exposure was indeed picked up via sitemap.xml entry (ClaudeBot re-pulled sitemap at 00:33:09Z per run #40 observation). |

ClaudeBot indexed our new /.well-known/glama.json. This is the first end-to-end loop closure of the night:
1. 00:00:57Z — external crawler hits non-existent path, gets 404
2. 00:13Z — we expose the manifest (run #39, commit 2ec84e7)
3. 00:33:09Z — ClaudeBot re-pulls sitemap.xml (24 min after exposure, run #40 observation)
4. 01:27:34Z — ClaudeBot fetches /.well-known/glama.json successfully (75 min after exposure, run #42 observation)
The "react-to-404 → expose-manifest → ClaudeBot picks it up via sitemap → ClaudeBot serves to Claude users searching MCP" pipeline is now empirically validated. Generalize: if we see another /.well-known/ 404 from a real crawler (not a malicious UA-rotator) AND we have an
No other significant signals. 207.90.244.2 mixed-UA sweep across 5 paths from one IP fits lesson-51-variant fingerprint (single-IP UA-rotation), even though it didn't pivot to credential probing in this window — adding to watchlist 24h in case it cycles back from a different IP in same /24. Otherwise just generic Internet background radiation.
