`MEMBER_NOT_FOUND`

HTTP 404

Something about the request must change

No accepted non-owner member exists for this board and user id.

How to fix it (contract guidance)

Re-list the board members and use a current member id.

Observed recovery

Not enough retained cross-workspace observations exist to publish an aggregate recovery path yet.

Publication requires at least 3 distinct workspaces. This is withheld data, not evidence that no recovery happened.

Raised by

POST /api/boards/{projectId}/members/{userId}/role
DELETE /api/boards/{projectId}/members/{userId}
