# Closed-Lost Reason Data Quality Check

## Inputs
Closed-lost export, the reason taxonomy, deal notes and the review period.

## Workflow
1. List closed-lost deals in the period.
2. Match each to a taxonomy reason; flag blanks and free-text duplicates.
3. Sample-check the stated reason against deal notes.
4. Return the quality report without editing records.

## Output contract
Deal | reason | taxonomy match | notes agree | flag | reviewer

## Fictional acceptance test
Fictional quarter: 26 closed-lost deals; 21 have a taxonomy reason, 3 are blank and 2 use free text duplicating 'budget'. Flag 5 records.

## Review gates
Re-check free text against the taxonomy before proposing a merge. Reason cleanup is a reviewed edit, not a bulk overwrite.
