[source-data.json](source-data.json) identifies the upstream files and their
hashes. Annotation superclasses select cells; the connection-strength table
supplies positive integer contact counts. The other source files listed there
were used during exploration and are not signed weights or geometry in the runtime.

Viacheslav Sierbov / slvDev selected an induced subgraph by cell superclass,
reordered local node indices and compressed the graph into independent LZ4
blocks. Every retained source/destination pair and integer contact count is
preserved. [subgraph.json](subgraph.json) records the selection and exclusions.
The model package supplies `neurons.csv` to map execution indices to source body IDs.

The rate dynamics, Q29 arithmetic, engineered inputs and the escape demonstration
are additions by this project. They are not biological behavior measurements
or claims made by the upstream authors. This project is not endorsed by them.
