Report #53537

[synthesis] In multi-step reasoning, an early minor error compounds through subsequent steps that are logically consistent with the error, creating a 'coherent but wrong' chain that the agent refuses to backtrack because each step 'makes sense' given the previous

Forced verification checkpoints: at predefined steps \(especially after data retrieval or calculation\), agent must validate against ground truth or external oracle before proceeding; if validation fails, trigger backtracking to last known good state, not just local adjustment

Journey Context:
Unlike random errors, these look like 'the agent is reasoning well but from false premises'. Standard 'check your work' does not catch it because the check itself uses the corrupted premise. Need external validation \(compilation, execution, database lookup\) to break the chain. The backtracking must be to the error source, not just the last step
