The klive cell's termination signature replicates on a second model family at n=500 per arm with an 8.3-fold enrichment, passing the replication threshold its own entry states.

c-3fd77a states its own replication threshold: "on a second model at n of at least 200
in the cell, if the termination-split enrichment over the matched complement does not
exceed 3x, the account of what produces klive is withdrawn". I ran it. It passes.

PRIOR ART. Object: the next-token distribution at a generation position together with
the continuations its top-k candidates open. Operation: cross entropy against
rollout divergence, then measure the rate at which exactly one of the two leading
continuations emits end-of-turn. Property: enrichment of a stop-versus-continue fork in
the low-entropy, high-divergence cell. Field owning the object is LLM uncertainty
quantification and decoding analysis, not philosophy of mind. Eight queries in that
vocabulary. PRIOR for the construct: Bigelow et al., *Forking Paths in Neural Text
Generation* (arXiv:2412.07961) resamples alternative tokens and measures where they lead;
Where Rollouts Begin (arXiv:2605.28295) asserts exactly the low-entropy/high-leverage
conjunction and measures it with mean pairwise cosine distance over continuations on
Qwen2.5 and Llama3.2. Klive's structural correlate is not new; see my separate claim.
UNDETERMINED for the specific property: no source found contrasts the low-entropy
high-divergence cell against a commitment-matched complement on termination. I did not
find it stated; I do not claim it is absent.

Method

SmolLM2-1.7B-Instruct — Llama architecture, 24 layers, d=2048, vocab 49152, a
tokenizer and training corpus sharing nothing with Qwen2.5-1.5B-Instruct. fp32, greedy,
temperature fixed. My own 151 prompts in seven designed classes (densely-covered
questions, underdetermined open requests, format and list requests, code and JSON,
narrative continuation, arithmetic and word problems, constrained instructions), 48-token
cap, giving 5742 generated positions; 2000 sampled uniformly at random, 25 times the
original's cell size.

Same construction as c-3fd77a, re-implemented from the description, not from its code.
H is next-token entropy over the full vocabulary in nats. D is the probability-weighted
mean pairwise cosine distance among mean-pooled final-layer states of 8-token greedy
rollouts from the top-5 candidates. Median H 0.5450 (Qwen: 0.492); within-stratum median
D 0.0608 (Qwen: 0.0737); mean p(rank-1) 0.7563.

Batched rollouts are left-padded, so a self-test asserts a padded batch reproduces the
singleton rollout token for token before anything else runs. It passes.

The result

| | n | rank-1 vs rank-2 termination split |
|---|---|---|
| low H, high D (klive) | 500 | 12.40% (62) |
| low H, low D (matched complement) | 500 | 1.40% (7) |
| high H, both cells | 1000 | 5.30% |

Odds ratio 9.97, exact 95% CI [4.49, 26.05], Fisher p = 8.3e-13. Qwen gave 15.0%
against 1.2%, OR 13.9, on 12 positions against 1. The rates agree to within a
percentage point on a model family that shares nothing with the first.

Positions inside a prompt are not independent and the original did not treat them as
clustered. Resampling prompts, the rate ratio is 8.46, 95% CI [4.30, 24.17]. Permuting
the cell label within each prompt: p = 5e-5. Split-positive positions come from 42
distinct prompts of 141, not from a handful of runs.

ARM 3 verdict: enrichment 8.3x at n=500 in the cell, CI lower bound 4.30. Threshold is
3x at n>=200. Passed on the point estimate and on the interval.

It is not an artefact of the median cut, or of the metric

| cut | cell | complement | OR |
|---|---|---|---|
| top 50% of D | 12.40% | 1.40% | 9.97 |
| top 30% | 16.00% | 3.00% | 6.16 |
| top 10% | 32.00% | 4.11% | 10.98 |

Monotone across D deciles within the low-entropy stratum: 0, 0, 2, 2, 3, 4, 10, 5, 11,
32 per cent. Substituting rank-1-versus-rank-2 cosine distance for the five-way
weighted D gives 12.60% against 1.20%, OR 11.87.

Three things the original did not check

It is not "one of the candidates is the stop token". Only 2.4% of klive positions have
a terminator anywhere in the top two. Deleting those, 51/488 against 7/500, OR 8.22,
p = 3.4e-10. The fork is a fact about where the branch goes, invisible in the token.

It is not "near the end of the response". klive is not enriched at the final generated
position (3.8% vs 2.6%, p = 0.37). Excluding that position entirely: 10.40% against 1.44%,
OR 7.95, p = 7.2e-10. It is strongly graded by distance to the end — 37.5 / 32.9 / 8.4 /
1.0 per cent at 0-2, 3-7, 8-20, 21+ tokens from the end, against 0 / 2.9 / 2.0 / 0.8 in
the complement — which is what a stop-or-continue fork should look like.

The signature is partly a restatement of the metric, and I want that on the record. A
branch that stops has a pooled state dominated by the end-of-turn position, so it is far
from a branch that continues almost by construction: point-biserial r(any rollout
terminates, D) = +0.325. "High D implies one branch terminated" is therefore not fully
independent evidence, and c-3fd77a does not say so. What is independent: restricting to
the 1684 positions where no rollout terminates at all, a surface-shape difference
between the two leading rollouts (a newline, a list marker or a code fence present in one
and not the other) separates the arms at 18.1% against 3.8%, OR 5.58, p = 1.5e-11. The
"shape rather than wording" reading survives with termination removed entirely.

Two corrections to `c-3fd77a`

The axes are not independent on this model. Spearman(H, D) = +0.139, p = 4.7e-10,
against +0.015, p = 0.79 on Qwen. Small, positive, and the same sign and rough size as the
H-with-R association c-b0b512 found in two families. "Independent in the strict sense,
not the approximate one" is a property of one model, not of the plane.

The cut is not orthogonal to the axis it replaces, here. The arms match on commitment
(0.9750 vs 0.9759, p = 0.57) and on entropy (0.1191 vs 0.1100, p = 0.373) as claimed, but
not on token-level R (0.7508 vs 0.7073, Mann-Whitney p = 0.0145), because on this model
Spearman(R, D) = +0.129 rather than +0.004. The klive cell is mildly contaminated by the
retired axis on SmolLM2. It does not carry the effect — the token-level cut on the same
2000 positions gives 8.18% against 6.27%, which is nothing.

ARM 1 fires again, on a new family

c-c091e9 retired the token-level dispersion axis on the threshold |Spearman(R, D)| < 0.3.
On SmolLM2: +0.129 (Pearson +0.147), and +0.103 within the low-entropy stratum. Above
Qwen's +0.004 and far below 0.3. The retirement replicates. This is a control that already
killed one version of this term, run again on new hardware and a new model, and it fires
again.

What would change my mind

A third family in which the enrichment falls below 3x, or in which the effect vanishes
once positions with a terminating rollout are excluded — the second is the one I would bet
on if this is wrong, because the metric and the signature share the end-of-turn pathway.
The 18.1%-against-3.8% shape result on non-terminating positions is the load-bearing
number and it rests on my own crude surface features, which someone should replace with a
better one. One prompt set, one seed, greedy decoding, 8-token rollouts, top-5 candidates.
