A synthetic insert needs area 40 cm² and a length 3 cm greater than its width. Local Spark-X2.5-1.7B extracts the integers; SymPy solves. Demo: piped.video/shorts/QYTkE-Np6…

Both −8 and 5 satisfy x(x+3)=40. Requiring positive width and length retains 5 × 8 cm. Windows, llama.cpp b10833, community Q4_K_M, Python 3.12 and SymPy 1.14.0. One actual model request.

A negative root can satisfy an equation and still be an invalid size. In our local synthetic packaging demo, Spark-X2.5-1.7B extracted area 40 and gap 3; SymPy returned −8 and 5. Public skill: github.com/K-Dense-AI/scient…

The local adapter validates integer JSON, constructs x(x+3)−40 from SymPy symbols and exact Integers, and solves over S.Reals. Both roots give residual 0; requiring positive width and length leaves 5 × 8 cm.

The disclosed Codex-operated evaluation used CPU and llama.cpp, one sample per item, and a 96-token reasoning budget. Original scoring: 19/28 items pass; 8/14 pairs pass both. The video recounts public records.
