RLC Resonance & Response Solver 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

Inputs at C = 0 or R = 0 produce undefined arithmetic and should be rejected. The specification also claims series/parallel support but supplies only the series Q formula, leaving parallel-Q behavior undefined.

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.
