`PROJECT_CONFIG_MISMATCH`

HTTP 409

Something about the request must change

The submitted configDigest does not match the enrolled project configuration.

How to fix it (contract guidance)

Recompute the digest over the exact committed .pullboard/project.json canonical JSON.

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/enroll
POST /api/projects/{projectId}/claim
