Run Field Interaction Probe

What Is It?

This experiment places two fixed positive sources on a two-dimensional diffusive field and moves a weaker negative probe vertically between them. The positive background remains present while the negative probe continuously disrupts it.

The result is a live cancellation and bridge-structure test. The visible field is not produced by an explicit Coulomb force law. It is produced by repeated local diffusion, source injection and boundary clamping.

What It Tests

The experiment asks whether recognisable interaction structure can appear when signed sources are allowed to share the same local field. The two positive sources create a stable background. The moving negative probe reveals how cancellation, weakening and field bridging change as the signed source geometry changes.

This is deliberately simpler than a full particle interaction model. It is a field-structure probe: a way to see whether signed local sources create organised spatial relationships before any explicit particle-force machinery is introduced.

How It Works

The field is stored as a scalar array. Each tick injects the source pattern into the current field, then relaxes each cell toward the average of its local neighbours. The two positive sources are fixed point-like cells. The negative probe is stamped near the centre and moved vertically by a sinusoidal phase.

Edges are clamped to zero, so the field remains bounded inside the visible domain. The probe keeps moving while the field diffuses, which exposes the changing relationship between the two fixed sources and the negative disturbance.

What Is Not Hard-Coded

• No explicit Coulomb force law is evaluated.
• No attraction or repulsion vectors are imposed.
• No analytic field solution is injected.
• No bridge or cancellation pattern is painted into the renderer.

The renderer displays the current scalar field. The signed sources, probe motion and local diffusion update produce the structure.

Why It Matters

The interaction probe is a small but useful midpoint between simple propagation tests and later field-mediated body dynamics. It keeps the geometry readable: two same-sign sources, one opposite-sign moving source, one shared field.

For CAELIX, the value is diagnostic. It shows how signed local source structure can organise a field without turning immediately to explicit pairwise forces. That matters because later SE and PE work depends on knowing when apparent interaction is carried by the field itself and when it has merely been imposed by a higher-level rule.
