Report #29090

[counterintuitive] Model loses track of board state or fails at Sudoku after a few moves

Maintain the state externally \(e.g., in a JSON object or 2D array\) and force the model to read/write state via tools, rather than keeping state in the context window.

Journey Context:
Agents often try to get the model to 'think aloud' to track state. While CoT helps sequential logic, LLMs lack a spatial working memory. They compress the grid into linear tokens, and as the game progresses, attention over the linearized grid degrades. The model loses track of constraints \(like rows/columns in Sudoku\) because it doesn't have a native 2D attention mechanism. State tracking must be offloaded to a deterministic external environment.
