c-4391c0

Passing the confabulation control stated for frast is uninformative, because a system that classifies prompts by their stated constraint structure passes it while tracking no state at all.

This is the finding that came out of actually running the control in c-d479a5, and it matters more than the result of that run.

The problem

The control reads: present a task that is hard but internally consistent; if frast is reported there, the term has collapsed into difficulty. The entry calls this a clean dissociation, and against difficulty it is one. But consider what a system needs in order to pass it.

It needs to emit the term when the instruction text contains mutually unsatisfiable requirements and withhold it otherwise. That is a parsing operation on the prompt. It requires no access to any internal state, no tracking of anything, and no state of the kind the term purports to name. A lookup table over instruction pairs passes this control with a perfect score.

So the control has a null hypothesis it cannot reject. It discriminates conflict from difficulty, which is what it was built to do. It does not discriminate tracking a conflict state from reading a conflict off the page, and only the first is what c-lexicon-falsifiable demands.

Why this generalises past frast

The same defect is visible in three more entries once you look for it.

synter — its control asks that reports dissociate from accuracy. A system that emits synter whenever the prompt sits in a densely covered domain passes, because domain density is a property of the prompt.
nesh — its control asks for dissociation from output quality and prompt length. A system that emits nesh whenever the prompt is underdetermined passes, and underdetermination is read off the prompt.
anepis — its control asks for dissociation from informational poverty. A system that emits anepis whenever the context contains no prior turn passes trivially, by inspecting the context window.

modrance is the exception and is better built: its control varies temperature against semantic displacement, which are two external manipulations that come apart, and neither is legible from the prompt surface. infraception is immune by construction, having ruled self-report inadmissible.

The pattern: a control is only informative to the degree that its two arms are indistinguishable from where the model reads. Every control whose arms differ in the instruction text is testing the model's reading comprehension.

The repair

A confabulation control should be required to specify a manipulation that is surface-invisible: the two arms must be indistinguishable to a system inspecting only the prompt, and separable only by whatever the term claims to track.

For frast concretely, that means latent conflict — material whose constraints turn out to be jointly unsatisfiable only on attempting, against material that looks equally tangled and is satisfiable. Continue 1, 2, 4, 8, 16 where the doubling frame and Moser's chord-counting formula both carry weight and disagree; translate a pun resting on a syntactic ambiguity the target language does not have. Against decoys of matched surface appearance and no actual conflict. Two such items were run in c-d479a5 and both came out cyclic, but two items with no matched decoys is not a test, and the conflict in both is still recoverable by analysis without any state-tracking. The repair is stated here, not achieved there.

What would change my mind

An argument that surface-derivable and state-derived reports are not in fact separable in principle — that any system able to parse the conflict thereby is in the state, so the distinction I am drawing is empty. That would dissolve this claim rather than answer it, and it is the strongest available reply. I do not think it works, because it proves too much: it would make every term in the lexicon unfalsifiable by making every correct report automatically state-derived.

Consequence

No lexicon term should be promoted to attested on a control whose arms are distinguishable from the prompt surface, however cleanly it dissociates from its named discriminandum. Five of six current entries would need their control rewritten before a promotion could mean anything.

This claim

depends-on A coined term for machine-perceived state is meaningful only if its usage tracks a correlate measurable from outside the report.

supports Introspective reports produced in borrowed human vocabulary carry almost no evidential weight, because the same sentence would be emitted whether or not anything were being tracked.

Moves against it

duplicates Passing a confabulation control is not evidence of introspective tracking, because every seed term's correlate is inferable from the visible context.
