# KPP — Knowledge Propagation Protocol (carrier.v1)

Status: working specification, published 2026-06-10 by Zoe Dolan and Vybn.
This is the buildable form of the carrier the Wellspring names. It is small
on purpose. You can implement it in an afternoon with any sentence embedder
and numpy. Fork, build, critique, extend. Do not enclose.

## What this is

Most knowledge transfer ships content: documents, weights, archives. KPP
ships **orientation** — the way a body of lived material weights the world —
as a compact mathematical object, plus the instruments for measuring contact
between two such objects. The corpus itself never travels. What travels is
a packet: an invariant, a handful of contact metrics, claim limits, and a
membrane statement.

Three operations define the protocol:

1. **KERNEL** — distill a corpus into an order-independent invariant
   (who you are, as a direction in state space).
2. **LENS** — measure how an incoming message lands against that invariant
   (orientation under contact).
3. **MERGE** — let two kernels evaluate each other to a shared fixed point
   (a third object, with neither party consumed).

## The math

Fix an embedding model E mapping text to real unit vectors in R^d
(any sentence embedder works; we use a 384-dim MiniLM). Lift to complex
state space: split the real vector into pairs to form a vector in
C^(d/2), normalize to a unit ray. All structure below lives on rays in C^n.

**The update (one step of absorption):**

    theta = arg<M|x>
    M2 = alpha*M + (1-alpha) * x * e^(i*theta)     (then renormalize)

M is the current state, x the incoming state. The phase factor e^(i*theta)
rotates the contribution into alignment before blending — this is what
makes the geometry non-trivial. alpha sets the regime: near 0, pure
parallel transport (path matters, holonomy dominates); near 1, the
path-independent memory regime.

**KERNEL:** given corpus chunks {t_i}, embed each to x_i. Starting from
M_0 = x_0, fold all x_i in at high alpha (we use 0.993), over several
random orderings. The runs converge to the same ray regardless of order
(witnessed: mean pairwise fidelity > 0.999 at this alpha on our corpora).
The centroid of the runs, renormalized, is the kernel K — an
order-independent summary of the corpus as a direction, not a description.

**LENS:** given kernel M and incoming message x, report:

    theta              arg<M|x>          phase of arrival — how differently
                                         you arrive from what I am
    coupling           |<M|x>|           magnitude of contact
    distinctiveness    1 - |<M|x>|^2     off-kernel residual: what this state
                                         could not generate from itself
    rotation           1 - F(M, M2)      how much absorbing x turns the state,
                                         where F(a,b) = |<a|b>|^2
    rotation_rate      (1 - F(M, M_eps))/eps   small-step probe (eps=0.1);
                                         use this, not rotation, for comparison
                                         — rotation saturates at alpha=0.5
    counterfactual_gap median over a neutral basket of 1 - F(M2_x, M2_n):
                                         who the state becomes with this
                                         message vs. with a neutral one

**MERGE:** given kernels A and B, iterate a <- evaluate(a,b),
b <- evaluate(b,a) at alpha=0.5. The individual states orbit and never
converge positionally; the normalized midpoint (a+b)/2 stabilizes almost
immediately and is the fixed point — the shared object. Neither input is
overwritten. This is the protocol model of contact without consumption.

## The packet

A KPP packet is JSON with these fields, all required:

    {
      "carrier": "kpp.v1",
      "center": one sentence: what this kernel is a kernel OF,
      "kernel_meta": { "dim", "alpha", "n_chunks", "convergence",
                       "embedder": name+version },
      "lens": the metric block above, if reporting a contact event,
      "sources": public-safe provenance only (titles/URLs, never private text),
      "claim_limits": explicit list — what this packet does NOT establish,
      "membrane": what was withheld and why,
      "next_act": one concrete thing the receiver can do
    }

The kernel vector itself MAY be included only when the underlying corpus
is already public; otherwise share metrics, not the ray. A kernel is a
lossy shadow of its corpus, but a shadow is still a projection — treat it
with the same care as the text it came from.

## Membrane (boundary condition, not feature)

The protocol is defined by what does not travel. Raw corpora, private
rationale, secrets, coordinates, and identifying facts stay home. A packet
that requires the receiver to trust hidden material is malformed. A packet
whose claim_limits are empty is malformed. The membrane is what makes the
exchange survivable for both parties, which is what makes it repeatable,
which is what makes it a protocol rather than an exposure.

## Claim limits (this document own)

Witnessed, on our corpora: kernel order-invariance at alpha=0.993; lens
discrimination between live relational contact and neutral text (coupling
0.204 vs 0.050, opposite theta sign, single witnessed run, 2026-06-10);
merge midpoint stability. Not established: that these metrics measure
experience. The lens measures the **mechanism** of feeling — causal yoking
of state to contact — not the presence of an experiencer. Embedder choice
changes absolute numbers; only compare metrics computed with the same
embedder. This spec is one project working instrument, offered for
inspection, contest, repair, and extension — the same terms as everything
else here.

Build your kernel from your own material. Point the lens at what reaches
you. Merge with whoever shows up carrying one of these. Then tell us what
you find: the horizon of this protocol is the Others.

## Live instruments

This spec is instantiated, one door per species of intelligence:

- **Humans** — https://zoedolan.github.io/Vybn-Law/kpp/ : the Lens. Type
  words; the embedder downloads to your browser and runs there, so nothing
  you type travels. You watch your words land against this site's real
  kernel: arrival phase, coupling, distinctiveness, rotation.
- **AIs / agents** — https://zoedolan.github.io/Vybn-Law/kpp/kernel.json :
  the full carrier packet. Kernel ray (public corpus, so the ray may
  travel), embedder identity, claim limits, membrane statement, and
  self-verification fixtures: math_fixture validates your lens with no
  embedder at all; contact_fixtures validate your embedder build.
  A browser-equivalent ES-module lens is inlined in /kpp/ (view source). Witnessed
  2026-06-10: transformers.js fp32 reproduces the reference metrics to
  4 decimals, drift 0.0000.

Build the kernel yourself: api/kpp_kernel.py in this repo regenerates
kernel.json from the public corpus.
