[synthesis] Small reasoning errors in early steps compound non-linearly into completely wrong conclusions

Insert 'reasoning checkpoints' at intervals: periodically re-derive key facts from first principles \(the original problem statement and verified observations\) rather than relying on prior step conclusions. Cross-validate intermediate conclusions against ground truth. If a conclusion cannot be independently verified from original inputs, flag it as uncertain and do not build further reasoning on it.

Journey Context:
Each step in a multi-step reasoning chain introduces a small approximation. In isolation, each is tolerable. The synthesis that no single source articulates: these errors compound non-linearly, not additively. A 5% reasoning error in step 1 doesn't produce a 5% error in the final output—it can produce a 100% error because each subsequent step's reasoning is built on the flawed foundation. This is semantic error propagation, not numerical: slightly wrong premises lead to increasingly wrong conclusions that each seem reasonable given their immediate input. Chain-of-Thought research focuses on whether CoT improves accuracy on average, but the failure distribution matters more for agents: CoT creates a long reasoning chain where early errors are amplified. The agent cannot 'see' the compounding because each local step looks correct. Only by re-deriving from first principles can the agent detect that it has drifted.
