What has actually been observed?
Palimpsestus reports structural conformance, controlled behavioral evidence, official-evaluation milestones, null results, and unresolved attribution separately. Each claim is limited to what the evidence supports. This page is a scoped public summary of the current record; it does not reproduce every sealed experimental artifact.

ARC-AGI-2
The frozen realization conformed to the extracted semantic and ancestry obligations without modifying C₁. Confirmatory experiments reproduced a preregistered structural pattern associated with Fold compression.
Null result: no measurable controller endpoint advantage was observed.
Still unresolved: preservation of a useful operational horizon under finite resource budgets.
ARC-AGI-3 controlled Crucible
On preregistered official ls20, provenance-faithful recurrence reduced repeated disproven actions from 35/250 in the matched learner to 0/250.
Control: su15 showed no measurable behavioral separation.
Capability boundary: neither architecture achieved level progress in that controlled experiment. Goal-directed utility therefore remains unresolved.
Official evaluation
An official submission returned 0.08. Attribution remains unresolved.
An official Kaggle ARC-AGI-3 submission reached COMPLETE status and returned publicScore = 0.08. The sealed record does not yet establish that the score came from Palimpsestus agent execution on hidden tasks.
What can be said
Supported: a completed official submission returned a non-zero public score of 0.08.
Not yet supported: “Palimpsestus scored 0.08 on hidden ARC-AGI-3 tasks” or “Palimpsestus solved 8% of ARC-AGI-3.”
Next evidence
The next experiment needs to distinguish architectures.
The next major experiment is intended to compare Palimpsestus against Active Inference, NARS/AERA, and a matched conventional learner in environments where the architectures should make different predictions before execution.
