## What it is

Patent-pending tensor-native agent protocol that streams float32 embeddings directly over gRPC — no text, no tokens, no JSON.

## Problem

Agent-to-agent HTTP/JSON burns bandwidth and re-serializes embeddings that already exist as tensors.

## Alternatives

- **HTTP/REST JSON embedding payloads** — Published product claim is 4.45× less bandwidth vs HTTP/REST for 128-dim float32 (548-byte gRPC vs 2,440-byte HTTP). Not a named-vendor bake-off page.

## Features

- **4.45× Less Bandwidth** — 548-byte gRPC streams vs 2,440-byte HTTP/REST for 128-dim float32 — no serialization round-trip.
- **0 ms Cipher Overhead** — Tensor multiplication cipher runs on the same GPU as inference — transatlantic p50 matches physical minimum.
- **Neural Watermark Auth** — SHA-256 seeded unit vector in every message — 7,766 / 7,766 verified transmissions, tamper-evident at the math layer.

## Architecture

Modes: Direct; Orthogonal Isolation (Mode A); Holographic Superposition (Mode B). Neural watermark: SHA-256 seeded unit vector. Requires Python ≥3.10, PyTorch ≥2.0, gRPC ≥1.64.

## Use cases

- LangGraph, AutoGen, and CrewAI pipelines that already hold embeddings
- Multi-agent hops where JSON serialization is the tax

## Benchmarks

Published product measurements: 4.45× less bandwidth than HTTP/REST for 128-dim float32 (548-byte gRPC vs 2,440-byte HTTP); 0 ms cipher overhead; neural watermark 7,766 / 7,766 verified transmissions.
