Devin repeatedly submitted identical docs PRs that kept getting rejected
Quick Answer
Devin caused a low-severity (2.2/10) infinite loop failure: Devin repeatedly submitted identical docs PRs that kept getting rejected. The root cause was pattern matching error. Spam-like behavior.
Description

Each was closed without merge, but Devin kept submitting the same fix. This pattern repeated across turnup4ethan2/datastack-demo-api with 4 identical "docs: auto-update API reference" PRs.
