7Works out the smallest useful **Access Matrix** setup for the business in front of it, then

9spreadsheet. Artifacts - CSV, SQL DDL, JSON Schema, Notion mapping - are produced on
10request, from one field list so they cannot drift apart.

14## When to Use This Skill
15 
16- who can access what matrix
17- role permission matrix
18- access control spreadsheet
19- who sees which data
