Latent reasoning architectures

Wiring block 23 back into layer 5 taught Qwen3-1.7B to hide reasoning from its monitor

A LessWrong experiment tapped a Qwen3-1.7B after block 23 and fed the result into layer 5 of the next token, then trained it to solve math while hiding the work from an LLM judge. The control failed the same objective.
