SAVED EXPERIMENT · GUARDED-83

Eight pieces, two shapes.

The same eight rigid pieces occupy part of a truncated icosidodecahedron and part of an equal-volume cube. They are a promising starting point, not a finished eight-piece puzzle.

Drag either view to rotate both · scroll to zoom · click a colored piece to select it. Matching letters and colors identify the same piece. Grey is unsolved material.

Removal follows the saved, numerically checked straight-line directions. Completed pieces leave the view; the unsolved material stays fixed. This is not a demonstrated path between the two assemblies.

What exactly was saved?

guarded-83 is the selected result of a guarded search with random seed 83. “Eight pieces” means eight connected physical groups; each group is represented by several convex cells for calculation. Those internal bookkeeping cells are not extra puzzle pieces.

All eight construction steps were replayed through the exact checker, yielding 26.995712% exact partial coverage. Separately, the saved numerical geometry passed removal checks at both endpoints, even with the unmatched material held fixed.

The widget uses that saved numerical geometry and its audited motions. Exact replay produced a separate construction, so its motion clearance is not certified here. Grip, tolerances, minimum thickness, and physical assembly have not been tested.

It is useful because it gives us a small, inspectable construction with recorded removal sequences. The next challenge is to add matched material without losing that property.
