Start by reproducing the document-opening failure from TimelineFragment.openFile and startOpenFileIntent, then trace the call through TimelineViewModel.handleOpenOrDownloadFile to ExternalApplicationsUtilKt.safeStartActivity. Compare the resulting error with the stack trace; done is an identified cause and a verified fix, but the issue does not specify expected behavior.
