The local collection / 816 cases

Different topologies. Clear connections.

Explore branching networks, bridges, transistor stages, and feedback loops. Distinct circuit graphs first, then their values, themes, and focus variants. Drawing, not simulation.

Small circuits. Serious checks.

Run the gallery and numeric boundary matrix locally. Check determinism, unchanged inputs, connectivity, and focus geometry.

Ready when you are.

Passing does not mean every input renders. An expected rejection is a passing check, not a renderer bug. Cancelled or errored runs cannot export a complete report.
