#Auditability

Build a versioned evaluation set and a regression gate that can reveal where a system starts to fail.

Bound a tool loop, distinguish failure from uncertainty, and recover without duplicating external effects.

Bring evidence, state, approvals, and recovery together in an inspectable travel-planning system.

Give conversation context, task state, evidence, and durable records clear owners and lifetimes.

Design stage contracts that catch malformed data, unsupported interpretations, and broken business rules.
