[synthesis] Agent compounds errors through high-confidence hallucinations treated as ground truth in downstream reasoning \(confidence anchor cascade\)

Implement explicit uncertainty quantification in chain-of-thought; require external validation or tool use for "facts" stated with high confidence in early reasoning steps before allowing them to serve as premises in subsequent steps

Journey Context:
Once an LLM states "The user wants X" or "Database Y contains Z" with authoritative tone in step 1, steps 2-N treat these as axioms even if step 1 hallucinated. The cascade appears logically valid \("If A then B; A; therefore B"\) but rests on false premises. The synthesis of formal logic \(validity vs. soundness\) with LLM calibration research shows that CoT validates structure, not truth. Common mistake is assuming CoT self-corrects or that "I think" prefixes reduce confidence. Temperature tuning affects sampling diversity, not epistemic calibration. External tool validation is the only reliable anchor.
