[counterintuitive] Model loses track of state in multi-step logic puzzles or grid manipulations

Externalize the state. Write the board or array to a file or variable, and write a script \(Python/shell\) to apply the mutation and print the new state. Do not ask the LLM to simulate the state changes in its head.

Journey Context:
When asked to solve a Sudoku or track a chess board, an LLM will confidently output a board that violates the rules. Autoregressive models lack a 'scratchpad' for discrete, exact state mutations. They predict what a solved Sudoku looks like, not how to derive one step-by-step. Even with Chain-of-Thought, the intermediate states are just text predictions, not enforced logical states. Writing a solver script bridges this gap.
