Report #53325

[synthesis] Agent remains confidently wrong across consecutive steps due to early false premise that propagates through dependent reasoning chains without triggering validation hooks

Insert 'assumption validation checkpoints' before any step that consumes outputs from >1 previous step; explicitly re-verify the root premises against ground truth rather than trusting the chain of derivations

Journey Context:
Standard self-correction prompts \('review your previous answer'\) fail here because the agent evaluates each step locally. Step 3 looks correct given Step 2, and Step 4 looks correct given Step 3. The error is in Step 2's false premise \(e.g., misreading a function signature\), but the agent has 'forgotten' that Step 2 was an inference, not a ground truth. Adding more reasoning steps actually makes it worse by building more structure on the rotten foundation. The common mistake is asking the model to 'check your work' within the same context, which only validates internal consistency, not external correctness. The fix forces a 'bottom-up' re-verification of load-bearing assumptions, breaking the cascade by questioning the foundation rather than the roof.
