`PROVIDER_PROOF_MISMATCH`

HTTP 409

Something about the request must change

Provider proof does not bind the requested repository and exact head.

How to fix it (contract guidance)

Confirm the pushed head exists on the bound repository, then resubmit.

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/submit
POST /api/verify
