Summary

A sigmoid probe metric separated abrupt transformer transitions from more graded state-space behavior.

Across eleven models, the proposed Ignition Index showed 9.6-fold selectivity over shuffled controls; feedforward transformers scored 89 percent higher in aggregate than state-space models, while a recurrent model ignited more strongly across iterations than depth. These probes operationalize one theory of workspace dynamics rather than measuring consciousness.
