GitHub user nathadfield added a comment to the discussion: Event-driven 
scheduling: duplicate DAG runs when an `AssetWatcher` runs on multiple 
triggerers

Thanks @VectorPeak, this was spot on. We upgraded to 3.2.2 and the duplicate 
runs are gone: a new commit to the repo our watcher polls now triggers a single 
DAG run instead of one per triggerer. So it was #65792, not a missing dedupe 
feature. We'll keep a small idempotency check as a safety net, but it's no 
longer doing the heavy lifting. Marking as answered, thanks for the help!
