**TLDR:** A tracking mechanism that records who changed data or processes, when, and how.

<p>An audit trail is one of the fundamental mechanisms for transparency and accountability in data systems. Questions such as who made which change, when a job ran, and which version produced a dataset are answered through the audit trail. This visibility is essential in regulated industries, security investigations, and high-risk AI infrastructures. An audit trail does not merely record the past; it also builds trust.</p>
