 ## Remaining Work
 
-### High Priority
-- **[Task 7b]** Obtain working iperf3 v3.21 binaries for Android arm64-v8a/armeabi-v7a
-  - Options: build with NDK + OpenSSL, or find pre-built binaries
-  - See README for build instructions
-  - Update `pubspec.yaml` to include assets in `flutter` section
-
 ### Future Enhancements
 - Add server-mode support (dual client/server toggle)
 - Add result parsing/formatting (extract bandwidth, loss, jitter)
