Could you build this?
No Non-intrusive test coverage using eBPF requires low-level Linux kernel programming, bytecode verification, and deep knowledge of DWARF debug symbols and CPU instructions.
What it would actually take: The system requires C or Rust (using libbpf/aya) to compile eBPF programs attached to kernel uprobes or tracepoints at user-space binary execution boundaries. The hard parts are mapping machine instructions back to source lines using DWARF debug info without slowing execution, handling inlined functions, avoiding probe overhead, and safely managing kernel memory verifier restrictions. This demands specialized systems and Linux kernel development expertise.
