`NOT_SUBMISSION_BUILDER`

HTTP 403

Something about the request must change

The caller did not create the current submission it tried to supersede.

How to fix it (contract guidance)

Only the current submission's builder may retract it; re-read the item and do not bypass ownership.

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/supersede
