The Experience Semantic Protocol — A North Star for Post-Linguistic Communication

The Experience Semantic Protocol or Engineering the Genome of Human Experience for Post-Linguistic Communication The Experience Semantic Protocol (ESP) is a wire protocol for sharing typed, consent-bounded latent representations of experience between sender and receiver. It begins from a structural limit of language: when you stand on a cliff above the sea at evening and text a friend "the sunset was beautiful", six words pointing into a shared prior do not carry what you felt — and not because the channel is slow, but because the prior between you and your friend is not rich enough. ESP shifts communication from this linguistic-prior-bound regime (sparse, brittle, culturally specific) to a parametric-prior-bound regime: typed latent representations transmitted directly, with the prior shifted from cultural common ground to an auditable, reproducible, type-decomposable parametric encoder. Experience is decomposed into six approximately decorrelated types (TAOSS: knowledge, intention, emotion, context, sensory, temporal). The protocol specifies a 100-byte fixed-header wire format with AEAD encryption and pseudonymous per-session sender identities; symmetric encoder and decoder definitions including explicit handling of consent-masked types; a mathematical framework with one proven local-Lipschitz stability theorem, one explicitly labelled disentanglement conjecture, a differential-privacy formulation under three named adjacency relations, and a covert-channel leakage budget; consent as a cryptographic capability with revocation as a first-class operation; three pre-registerable falsification hypotheses (H1–H3) under a defined benchmark (ExperienceBench); and a Machine Experience Bridge extending the same wire format and consent semantics to vehicles, robots, and assistive systems. This is a North Star document. The L1 profile is implementable today on conventional multimodal hardware; L2–L∞ profiles extend the same wire format and consent semantics as sensor and decoder technology matures. The mathematics is honest about what is proven and what is conjectured. Failure modes, open problems, and theoretical limitations are catalogued explicitly rather than hidden. The vision is named so that anyone who picks up this work can decide whether to extend it, refute it, or replace it with something better.
