Trust Isn't a Scalar: Typed Provenance for Agent Chains
Summary

A single trust score (boolean or scalar) for agent chain outputs collapses under real-world conditions because degradation occurs along different axes—freshness, capability, citation validity—and downstream consumers have conflicting requirements. The correct model is typed provenance: propagate a vector of what-was-degraded-and-how alongside each result, letting each consumer apply its own policy. This aligns with emerging frameworks like TrustBench that keep dimensional scores per trust aspect weighted by domain.
