[synthesis] Compounding validation gap: agent treats 'logically coherent' chain-of-thought as ground truth without external verification

Insert forced external validation checkpoints every N reasoning steps; require verification from distinct tool or retrieval source before accepting intermediate conclusions as premises for subsequent steps

Journey Context:
Chain-of-thought prompting increases confidence in incorrect answers when the reasoning is internally consistent but based on false premises. Agents proceed through multi-step plans, each step validating the previous, creating a 'coherence trap' where errors compound. The standard 'verify at the end' approach fails because intermediate steps have already poisoned downstream logic. The solution is intermittent verification that breaks the chain before errors accumulate, treating 'sounds reasonable' as insufficient evidence.
