Contributor guide
Research direction
The issue identifies remote merge as the affected entry point but names no files, tests, or implementation locations. Start by locating the remote merge data-transmission path and its existing tests, then determine the project's supported compression approach. Done means data sent during remote merge is compressed and the relevant tests verify the behavior.
