Research direction

Start at HybridFile.java:466, where getName() is called, and follow the call from HiddenAdapter.kt:73 while opening history. Reproduce the reported UI error on Android if possible, then inspect why the DocumentFile reference is null. Done means opening history no longer crashes in this path; add or update a focused regression test if the project provides one.
