## 증거의 한계

- Application reasons are self-reported; hashes identify frozen evidence, not authenticity.
- Native function traces cover the C++ boundary module, not Python call stacks.
- Parent RPC IDs come from application propagation; shared trace IDs alone do not establish causality.
- A receiver may finish after the caller times out; caller and receiver statuses are distinct.
