Struct ProcessIdentity 

pub struct ProcessIdentity {
    pub pid: u32,
    pub start_token: String,
}

A process’s identity strong enough to survive pid reuse.

pid alone is not enough: the OS recycles pids, so a different process could later hold the pid recorded in a stale lock. start_token is an opaque, process-specific string (the OS-reported start time) that changes when the pid is reused, so a lock is only “held” when both the pid is alive AND its live start token matches the recorded one.

Fields

pid: u32

start_token: String

OS-reported process start marker. Empty when the platform could not report one; liveness then degrades to a bare pid-alive check (documented tradeoff).
