Struct WindowsPrincipal 

pub struct WindowsPrincipal {
    pub sid: Arc<str>,
    pub pid: Option<u32>,
}

A principal the kernel proved, on a Windows named pipe.

The client’s token SID, read through ImpersonateNamedPipeClient on the serving side and captured once at connect time (docs/research/ipc.md §3.3, [0010 §4.4]). The same two rules as LocalPrincipal: the credential is the one taken at connect, and the PID is an observation that MUST NOT be authorized on — GetNamedPipe ClientProcessId reports it and nothing signs it.

A separate type rather than a third field set on LocalPrincipal, because a SID and a uid are not comparable values and a caller that authorizes on one must be made to say which. The SID is an Arc<str> rather than a String so that a PeerIdentity stays a refcount bump to clone: it is copied into every incoming transfer’s metadata, and a string allocation there would be one per message.

Fields

sid: Arc<str>

The account SID in its string form (S-1-5-21-...).

pid: Option<u32>

The client process id, where the pipe reports one. An observation only.
