What this Lesson covers
Use AI to build a traceable cleaned table while keeping raw values, IDs, and unresolved issues visible.
Lesson outline
- Keep raw and clean values side by side
- Exclude only the affected metric, not the whole record
- Give AI an approved treatment plan
- Inspect the implementation, not just the summary
Learning outcomes
- Preserve source links
- Apply supported changes
- Use metric-specific flags
Clean without Losing the Evidence
The inspection found safe label and date changes, one exact repeat, three unsupported values, and valid cancelled-session blanks. The source still remains unchanged.
