A Sovereign Physical Layer for the 6G Era

One coherent-optical waveform carries communication and nine-dimensional physical sensing — verified on silicon — on its own link, free of 3GPP standard-essential patents and spectrum licensing.

Single capture, dual decode  |  10,567,680 bits at zero error  |  information-theoretic secrecy, verified  |  two harvests per device, one field per network

Conventional ISAC splits one waveform by time-slots and pilot insertion — communication and radar fight for the same resource, glued together by heavy algorithms. V131 is different at the root: transmitter and receiver read the same waveform ledger (the S01 physical anchor — “what we emit is what we accept”), so sensing and communication are born from one physical identity, not synchronized after the fact. And because the medium is coherent optical, not licensed radio, the radio-frequency standard-essential patents that gate the cellular world do not read on it, and no spectrum auction gates deployment. The network is not a tenant in anyone’s building.

The two decoders consume the same original capture file (pinned by SHA-256) — not two separate acquisitions. That single-capture, dual-decode property, verified through an FPGA link at zero bit error over 10.57 million bits, is the electrical-level proof that “one waveform, two harvests” is real, not a marketing composite.

Security here is not a slogan — it is a pre-registered, falsifiable result. Threat model (Kerckhoffs): the adversary knows the entire system, captures the full ciphertext, and may hold known plaintext — but does not hold the key (the S01-derived one-time material). Under that model, the keyed construction (one-time pad + encrypt-then-MAC) is verified to deliver:

Two deliberately-broken canary constructions — key reuse (two-time pad) and integrity stripped — are correctly caught and fail the criterion. A judge that cannot fail is no judge; these prove it has teeth.

What “absolute” honestly means here. This is Shannon information-theoretic perfect secrecy — I(ciphertext; plaintext) = 0, so brute force does not help — but it is absolute only inside its stated model, exactly as the one-time pad has been provably unbreakable for eighty years given its assumptions. The guarantee carries its price and preconditions, which is precisely what lets it survive scrutiny:

• Three preconditions: the key is truly random, kept secret, and used once; and ciphertext integrity is protected by the MAC. Break any one and the guarantee is void.
• Capacity price (Shannon’s price): the secure payload cannot exceed the key material — measured in time samples of the ψ(t) waveform, the physical one-time pad. Beyond that, one re-keys or drops to computational-grade security.

We therefore do not publish “unconditionally absolute security.” We publish something stronger because it is true: perfect secrecy under an explicit threat model, with its preconditions and capacity stated.

Per-device ISAC is the starting point; the network form is the Tensor Potential Field (TPF). Every device writes its nine-dimensional measurements into one shared field and reads back the risk-weighted cost of every action — coordination stops being a negotiation protocol and emerges in the field. (Field-scale results below are simulation, reproducible on GPU.)

• Measure once, reuse network-wide: multi-device fusion +5.6 dB — one node detects a hazard, the network reroutes before arrival.
• 10k-scale airspace: 16,384 drones coordinated online in one airspace; one hazard broadcast reroutes the network in a single step.
• No cooperation required: non-participants are written in as measured objects — penetration rate falls from a life-or-death threshold to a mere density parameter.
• Poisoning does not break it: injected false data — 100% detected, 0% false accusations.

Every claim above is bound to a pre-registered, falsifiable criterion — locked before the run, allowed to fail, failures filed as-is (the two security canaries are designed to fail, and do). Same stance as the rest of V131: run toward the tests, not away from them.
