- Missing-field review
- Format validation
What you receive.
Cleaned records with a change log and flagged exceptions.
Demo / Illustrative example
Make the output tangible.
This synthetic example shows the structure of a record. It is not a client dataset or a claim of project performance.
Labels with a clear purpose.
Deduplication is defined in the project guidelines. Ambiguous examples are flagged for review instead of silently forced into a category.
{ "record_id": "demo-1", "duplicate": false, "status": "schema-valid" }Human-in-the-loop quality
Quality is a process. Not a percentage on a page.
Acceptance thresholds, review methods and sampling are agreed for each project. Calibration happens before volume.
