[synthesis] Agent treats uncertain intermediate conclusions as certain premises for subsequent reasoning steps, causing error rates to compound exponentially with depth

Implement 'uncertainty tagging' where each reasoning step outputs a confidence score \(0-1\); subsequent steps must discount their own confidence by the product of all parent step confidences, and halt if the cumulative confidence drops below a threshold.

Journey Context:
Chain-of-Thought shows reasoning steps but not certainty. An agent might say 'Step 1: 80% sure X is true' then 'Step 2: Therefore Y is definitely true.' The model has no mechanism for uncertainty propagation like Bayesian networks. Standard prompting asks for confidence at the end, not per step. The multiplicative rule forces the agent to recognize that a chain is only as strong as its weakest link; if Step 1 is uncertain, Step 5 cannot be certain even if the reasoning sounds solid. This prevents the 'confidently wrong' syndrome in deep reasoning chains by quantifying and propagating doubt.
