[synthesis] Agent chain-of-thought escalates false certainty as tentative early assumptions become frozen in subsequent reasoning steps

Implement explicit 'assumption tagging' in the reasoning trace where uncertain premises are marked with confidence scores, and force a re-evaluation step when the chain exceeds 3 steps from the original assumption.

Journey Context:
In multi-step reasoning, LLMs generate tokens autoregressively, conditioning each new token on the previous context. When an agent makes a tentative guess in step 1 \('Perhaps X is the cause?'\), that text becomes part of the context for step 2. The model's probability distribution shifts to make X more likely to be true in step 2 because it's already 'written' in the context. By step 4, the agent is treating X as established fact, even if it was originally a low-confidence hypothesis. This is different from confirmation bias; it's a mechanical property of autoregressive generation. The fix requires architectural intervention to flag and periodically re-evaluate early premises outside the autoregressive context.
