[synthesis] Agent compounds errors across steps because uncertainty from earlier steps is not propagated forward

Explicitly propagate uncertainty metadata through reasoning chains; halt or escalate when cumulative uncertainty exceeds threshold

Journey Context:
In chain-of-thought reasoning, an agent might be 60% confident in step 1, but by step 5 it treats conclusions from step 1 as 100% certain ground truth. This is 'confidence collapse'. Standard CoT lacks explicit uncertainty quantification. The synthesis is that agents need to treat previous conclusions as probabilistic priors, not facts. Implementation requires tagging each reasoning step with confidence scores and propagating these through Bayesian updates or simple threshold checks. When cumulative uncertainty exceeds a threshold, the agent must halt and request clarification rather than hallucinating forward.
