`HEAD_NOT_PUSHED`

HTTP 409

Something about the request must change

The submitted headSHA is not reachable from any pushed remote branch, so another principal cannot verify it.

How to fix it (contract guidance)

Push your branch (or push HEAD to the trunk), then resubmit the exact pushed SHA.

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
