`COMMIT_ID_FORBIDDEN`

HTTP 400

Something about the request must change

A commit id was supplied where this work type or phase forbids one.

How to fix it (contract guidance)

Omit commit fields for attestation items; only code verdicts carry commits.

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
