Research direction
Investigate how radare2 currently handles core dumps, review systemd's coredumpctl interface, and implement automatic loading from standard locations (e.g., /var/lib/systemd/coredump on Linux). Check for existing related code in the radare2 codebase. The issue has an assignee, so coordinate with them if needed.
