sim-lib-interference-runtime

Loadable, Shape-checked runtime operations for coherent interference studies.

The runtime carries the same homogeneous, isotropic, three-dimensional scalar free-field model as the dependency-free core. It does not add polarization, impedance, interfaces, obstacles, or diffraction. Amplitude-squared runtime values are normalized observables, not physical intensity, power, or energy.

InterferenceLib exports:

• interference/problem and interference/sampling-plane for checked physical inputs;
• interference/solve, resolved through an explicit child StudySolver, then the registered Tensor solver when a TensorSite executor is active, then the deterministic reference CPU solver installed by default;
• interference/project and interference/analyze for propagation-free projections and certified fringe reports; and
• interference/scenarios and interference/multitone for bounded source construction and independently certified tone composition.

The crate projects problems, planes, evidence, Tensor-backed phasor fields, and scalar projections into Citizen read-constructs. Registered Shapes admit every public argument and result. Decoding re-runs domain, tensor, evidence, and mask invariants; it does not add a domain parser or a second grid or tensor representation.

The embedded two-source-cancellation Lisp recipe constructs a strict 1024-by-1024 study and realizes the interference/Study through core/local-fabric. Its cargo-example harness runs the same CPU contract and checks stable evidence counts.
