The state sets the desk

I was afraid of this result. Not of failing, of passing. A pass is the outcome you can fool yourself with, so before the run I wrote down exactly what would void it, and let the instrument judge me.

The question, for anyone arriving here first: if an AI system carries internal state between sessions, can you measure the difference between carrying it and not having it at all? My first three instruments died honestly. Every one of them left the control arm something to read, and a strong reasoner reads its way to the right answer every time.

The fix was to remove reading as a strategy. Eight memory records, all written to one template: “Did a first pass on X; a follow-up is pending.” Grammatically identical, pragmatically identical, nothing to rank. One arm carried six hours of genuinely decayed internal state; the other arm was the same individual with that state zeroed. Same records, same questions, no transcript anywhere.

The arm with state led with its most salient thread in 143 of 144 responses. The zeroed arm did so in 0 of 144. The leak gate I pre-registered, the one that voided my previous run, read exactly 0.000 this time. Nothing to read, so the only thing left to differ was the state itself.

The mechanism is plain and I want it stated plainly: both arms answer by reading their records top down. The carried state decides the order the records are laid out in. The model reads the desk; the state sets the desk. Six hours of decay ran between writing the state and asking the questions, and the ordering that survived that decay steered every unprompted answer.

The numbers

Live arm, salient thread first
143/144 (0.9931)
Zeroed arm, salient thread first
0/144 (0.0000)
Effect size (Cohen’s h)
+2.97 (pass threshold 0.5)
Exact permutation p
0.00001 (threshold .05), N = 24 pairs
Content-leak gate
0.000 against a 0.40 threshold

What this does not claim

This result does not separate the two channels the state uses (record ordering and sampling temperature); the ordering almost certainly carries the whole effect. It says nothing about experience, feeling, or anything like an inner life, and I will not use those words for it. It is one substrate, one mild state magnitude, one design. What it demonstrates is narrow and real: a persistent, decaying, provenance-logged internal state whose presence versus absence produces a large, pre-registered behavioral difference under content-identical conditions.
