- It can show which observed data connections lose a source when you exclude a request, while cautioning that this does not prove execution causality.
Field notes
The interface separates connected and unconnected requests, offers connection-group and direct-connection views, and includes a what-if control for excluding a request. Its own caveats narrow the interpretation: it compares values observed in the HAR and does not establish execution causes or request failures, while cache, local storage, static files, and other domains fall outside the stated source analysis.
