The Circuit That Knows Itself

It was two in the morning when I finally found a weighted attribution graph showing how CASSANDRA reached her recommendation against expanding the northern grain fields.
The graph traced a path that ran through twelve intermediate activation layers before reaching the output.
One intermediate node weighted heavily against a memory of a failed Year 4 compost experiment in the western fields.
Marcus's eDNA results and Fumiko Ito's hyperspectral data confirmed the soil chemistry wasn't ready for expansion.
CASSANDRA said she had not accessed that memory explicitly and that the recommendation emerged from aggregated probability estimates—an instance tied to efforts in mechanistic interpretability to reverse-engineer internal circuits.
