[synthesis] Multi-step agent produces confident wrong answers where errors in early steps cause logically consistent but false conclusions in later steps

Implement explicit uncertainty quantification at each reasoning step and force verification of premises against ground truth before conclusion synthesis; halt chain when confidence < 0.8

Journey Context:
Unlike single-step hallucinations, agents develop 'structured delusion' where step 3's low-confidence error becomes the foundation for steps 4-8. Each subsequent step is logically valid given the false premise, making the error invisible to standard consistency checks. 'Verify your work' prompts fail because the agent uses the same corrupted context for verification. The fix requires external premise validation and calibrated confidence thresholds that break the chain when uncertainty accumulates.
