Sensors as points. Pairwise baselines paint the uv-plane. Incomplete sampling → dirty image.
Earth-rotation fills arcs over time. CLEAN reduces artifact haze — it does not invent missing baselines.
Gaps stay UNKNOWN.

Coverage gaps
Named UNKNOWN — never coerced to false or filled by guess.
Pairwise agreement
Demo meter — mock data, labeled as such.

What CLEAN does here
In interferometry, CLEAN iteratively subtracts bright components to suppress sidelobe artifacts
in a dirty image. In this sketch, CLEAN lowers haze opacity and sharpens visible peaks —
but coverage holes listed as UNKNOWN stay listed. No phantom baselines are drawn.
