# Audit Trail

## Overview

The Audit Trail category provides record-level compliance and traceability widgets for Labii ELN and LIMS. These widgets help teams review who changed a record, what historical versions exist, and who accessed the document over time, all without leaving the record context. Together, they support internal quality review, deviation investigation, approval workflows, and regulated documentation practices that depend on transparent audit evidence. Whether you need event-by-event changes, immutable version checkpoints, or a simple visitor log, this category keeps critical record history visible inside the working document.
