[architecture] Low-confidence outputs propagate through agent chains causing compounding errors without triggering review

Implement a calibrated confidence scoring layer where each agent emits a confidence tier \(High/Medium/Low\) based on logprob analysis or self-consistency checks; route Medium through a peer verification agent and Low to human-in-the-loop.

Journey Context:
Raw LLM logprobs are poorly calibrated—high probability doesn't mean high accuracy. Teams often ignore confidence entirely or use arbitrary thresholds. This pattern uses either temperature-sampling self-consistency \(majority voting\) or trained calibration models to map internal states to actionable tiers. The tradeoff is token cost \(running multiple samples or reflection\) versus catching errors early. Without this, agents confidently hallucinate facts that downstream agents treat as ground truth.
