Struct ObservedJid 

pub struct ObservedJid<'a>(/* private fields */);

Privacy-aware Display wrapper for a Jid, for use in tracing fields.

Pseudonymous (LID) and non-personal (newsletter/bot/call, modern group ids) JIDs render in full, so the same peer/chat correlates across spans. JIDs whose user is a phone number (Server::carries_phone_number) render the user as a pn#<token> instead — preserving correlation without leaking the number. Legacy group/broadcast ids of the form <creator-phone>-<timestamp> get only the numeric prefix redacted (pn#<token>-<timestamp>), keeping the timestamp.

The token is a keyed hash (SipHash via a process-lifetime random key), not a plain digest of the number: the phone-number search space is small, so an unkeyed hash would be reversible by precomputation. The random key lives only in process memory, so exported traces cannot be brute-forced back to numbers. It is stable within a process run (correlation works) but not across restarts (a fresh key each start). Enable the tracing-pii feature to render raw numbers (local debugging only). The token is computed only while formatting an already-enabled span, so it costs nothing on disabled call sites.
