+# GlideRecord Field-Level Audit
+
+## Description
+This snippet compares two GlideRecord objects field by field and logs all differences.  
+It is useful for debugging, auditing updates, or validating changes in Business Rules, Script Includes, or Background Scripts.
+
+## Prerequisites
+- Server-side context (Background Script, Business Rule, Script Include)
+- Two GlideRecord objects representing the original and updated records
+- Access to the table(s) involved
+
+## Note
+- Works in Global Scope
+- Server-side execution only
+- Logs all fields with differences to system logs
+- Does not modify any records
+## Usage
+```javascript
+// Load original record
+var oldRec = new GlideRecord('incident');
+oldRec.get('sys_id_here');
+
+// Load updated record
+var newRec = new GlideRecord('incident');
+newRec.get('sys_id_here');
+
+// Compare and log differences
+fieldLevelAudit(oldRec, newRec);
+```
+
+## Output
+```
+Field changed: priority | Old: 5 | New: 2
+Field changed: state    | Old: 1 | New: 3
+Field changed: short_description | Old: 'Old description' | New: 'New description'
+```
