`PROJECT_PROOF_INVALID`

HTTP 403

Something about the request must change

The provider adapter did not confirm this account administers the exact repoId.

How to fix it (contract guidance)

Verify repo admin rights and the claim nonce, then retry; unavailable proof fails closed.

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/projects/{projectId}/claim
