    What this 2D world can’t tell

    We only measure the circle’s size. That’s real data, but it’s incomplete.

    Even with perfect math, depth has a mirror ambiguity: z = ±|z|.

    Two different hidden paths can produce the same slices.

    What to try
    • Change Reality (hidden) to change what’s happening.
    • Change Working Model to change the prediction.
    • Watch Error (Residual) to see drift.
    • Use Auto-correct to see the model recover.
