Contributor guide

Research direction
Investigate why the tracer fails to find the process during dynamic analysis. The ESRCH error suggests the target process no longer exists when the tracee attempts to attach or control it. Check if the child process exits prematurely due to a race condition or incorrect process lifecycle handling. Look at the code that forks/execs the binary and attaches the tracer (likely ptrace). Ensure the child is properly waited or traced before the tracer tries to interact.
