How it works
Weight privileged actions
Broad delete access, contributor guests and missing audit records increase the permission-risk score.
Produce a minimum matrix
The output starts with member, admin and only the extra specialized roles justified by the inputs.
Frequently asked questions
Should every job title become a product role?
No. Product roles should represent meaningful permission differences. Keep job titles in profile data unless they change access.
What is least privilege in an MVP?
Give each role only the actions needed for its primary workflow, with privileged actions limited and logged.
Can permissions be hardcoded for the first release?
A small role set can be implemented simply, but access decisions should still be centralized and tested rather than scattered through UI code.
Does hiding a button enforce permission?
No. The server or authoritative data layer must enforce access even when a request bypasses the interface.
