The AI Audit Trail Is a Product Feature, Not a Compliance Checkbox
McKinsey's 2025 survey found that 75% of business leaders were using generative AI in some form — but nearly half had already experienced a significant negative consequence. That gap is not a model quality problem. It's a trust problem. And the fastest path to closing it is not more evals, better prompts, or a new frontier model. It's showing users exactly what the agent did.
Most engineering teams treat the audit trail as an afterthought — something you wire up for GDPR compliance or SOC 2, then lock in an internal dashboard that only ops reads. That's the wrong frame. When users can see which tool the agent called, what data it retrieved, and which reasoning branch produced the answer, three things happen: adoption goes up, support escalations go down, and model errors surface days earlier than they would from any backend alert.
