Report #22761

[synthesis] Agent persists with an incorrect approach for multiple consecutive steps because early errors in reasoning create a 'foundation of sand' that subsequent steps build upon, with confidence increasing at each layer despite accumulating errors

Implement progressive validation checkpoints: force the agent to validate intermediate outputs \(code snippets, search results, calculations\) against external ground truth \(test cases, type checkers, documentation\) before allowing those outputs to be used as inputs for subsequent reasoning steps

Journey Context:
This is the 'compound error' or 'telephone game' effect in multi-step reasoning. The first step makes a small error \(wrong variable name\). Step 2 reasons about the variable, propagating the error. By step 5, the agent has built a complex justification for why the code works, including the wrong variable. Confidence metrics \(if used\) often increase with token count or step count. Simple 'chain-of-thought' doesn't prevent this because the reasoning is internally consistent with the false premise. External validation acts as a reality anchor—if step 1's variable doesn't exist in the codebase, the agent must correct it before proceeding, preventing the cascade.
