Humotica Humotica This document defines the MUX Status Frame, a two-octet, relationship-scoped signal that lets a multiplexing routing layer tell a proven, related peer that a destination is unavailable - offline, not in session, superseded, or permanently revoked (tombstoned) - while disclosing nothing to the open network. It resolves the tension between two failure modes of a null-routing mux: silently dropping traffic to a dead peer (a false positive - the sender believes it landed) and answering honestly to everyone (an enumeration oracle mapping who is alive, dead, or revoked). Honest status travels only on a relationship-scoped trusted path; to the world, and to any merely authenticated but unrelated peer, the entire frame is zero. Status is derived from the canonical naming record and session liveness, not from a separate blocklist. The encoding is deterministic so independent implementations agree byte-for-byte. This protocol is transport-agnostic and complements JIS [JIS], AINS [AINS], TIBET [TIBET], and RVP [RVP].
