Logic Gate Circuit Simulator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

A cyclic netlist such as a NOT gate whose output is wired to its own input has no stable Boolean result. If accepted without cycle detection, live propagation may oscillate or fail to converge; the simulator should reject it or report undefined output.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.
