`INVITATION_INACTIVE`

HTTP 409

Something about the request must change

The board invitation was revoked, expired, or already settled and cannot be accepted or resent.

How to fix it (contract guidance)

Ask the board owner to create a new active invitation if access is still needed.

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/invitations/{invitationId}/accept
POST /api/boards/{projectId}/invitations/{invitationId}/resend
