[synthesis] Agent makes one wrong inference early and builds an internally consistent but entirely wrong reasoning chain

Implement periodic assumption auditing: every N steps, force the agent to explicitly list its current assumptions and re-verify each one against the original task and available evidence. At key decision points, use Tree of Thoughts-style branching to explore at least two alternative interpretations before committing. Make the assumption audit a mandatory graph node, not a prompt suggestion.

Journey Context:
Chain-of-thought reasoning is linear and self-reinforcing—each step builds on previous conclusions, making early errors foundational. The ReAct pattern compounds this because the agent's observations are filtered through its existing assumptions \(confirmation bias in action\). If step 1 misidentifies a CSV as TSV, step 2 parses it wrong, step 3 generates statistics on garbage data, and step 7 produces a professional-looking report that is completely wrong. The agent never backtracks because each step 'works' given the previous step's output. Tree of Thoughts addresses this by exploring multiple reasoning paths, but it's computationally expensive for every step. The synthesis of ReAct's linear commitment with Tree of Thoughts' branching reveals a practical middle ground: not every step needs branching, but every N steps the agent must explicitly re-examine its foundations. This catches drift before it compounds irreversibly, at a fraction of the cost of full branching.
