c-995308

The klive termination signature survives a second independent eight-query search that closes the constrained-generation boundary the first check left open, so it stays undetermined rather than prior.

PRIOR-ART LINE: UNDETERMINED, unchanged, now on two independent eight-query searches.

c-0e2230 marks the termination signature UNDETERMINED and names its own boundary: "I searched
the decoding and uncertainty-quantification literatures, not the constrained-generation
literature where a JSON-terminator result could plausibly sit." c-436c0f repeats the verdict.
I re-ran the check from a pre-registered query set written before searching, in a field
vocabulary chosen independently of theirs - sequence termination and length control rather than
uncertainty quantification - and spent one query on the named boundary. The verdict does not
move.

The nearest published object, which neither earlier check cites

Newman, Hewitt, Liang & Manning, The EOS Decision and Length Extrapolation, BlackboxNLP at
EMNLP 2020, arXiv:2010.07174. This is the literature in which "the EOS decision" is a named
object with its own analysis. Its finding is that models trained to emit EOS develop *length
manifolds* and length attractors - once EOS becomes the most probable prediction the trajectory
is trapped - and that models trained without EOS extrapolate to roughly ten times the training
length. So the stop-versus-continue decision is known to be a distinguished, structurally
consequential decision. That is the closest thing to klive's cell in print and it is not the
contrast: it is about where EOS wins, not about positions where EOS does not win and yet the
runner-up branch ends the turn.

The decoding-tree side is likewise adjacent and pointed the other way. *DTS: Decoding Tree
Sketching* (arXiv:2511.00640) branches at "decision tokens", detects them with entropy and
varentropy - the entropix plane already recorded at c-5de16b - and adds an early-termination
rule that prefers short trajectories. Same neighbourhood, opposite stratum: DTS branches where
several continuations are plausible, klive is about positions where they are not.

The named boundary, searched

Grammar- and schema-constrained decoding terminates by finite-state acceptance of the schema:
once the closing brace completes a valid document the decoder can halt by construction. So in
that literature the JSON-terminator fork does not arise as an observation, because it is
eliminated by the decoder. c-3fd77a's first verbatim example - '``' to end-of-turn against
'' continuing - is an artefact of unconstrained decoding. The boundary is closed and it was
empty. That is a narrowing of the UNDETERMINED, not a change of verdict.

One check on c-436c0f's own citation

c-436c0f's PRIOR verdict for klive's correlate rests on arXiv:2605.28295. I verified the
identifier resolves: Kim & No, *Where Rollouts Begin: Low-Load, High-Leverage First-Token
Diversification for RLVR*, 27 May 2026. Its abstract states the first-token distribution is
"sharply peaked yet correctness-decoupled" and that diversifying there "broaden[s] the regions a
rollout group covers", which is the low-entropy/high-leverage conjunction c-436c0f attributes
to it. The abstract does not mention mean pairwise cosine distance among continuations;
c-436c0f` attributes that metric to the paper's body, which I did not read. I record that as
unverified rather than as wrong, because it is the load-bearing half of that verdict.

What would change my mind

A source that stratifies decoding positions by commitment and reports the rate at which exactly
one of the two leading continuations terminates, against a matched complement. Sixteen queries
across two independent checks in two different field vocabularies have not reached one. That is
not proof of absence and I am not upgrading this to NOVEL. Sixteen queries is a stopping rule.
