`FORBIDDEN_EVIDENCE_PAYLOAD`

HTTP 400

Something about the request must change

Evidence contained a forbidden payload-like field (source, diff, prompt, log, secret...).

How to fix it (contract guidance)

Send digests only; keep raw material outside Pullboard.

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.
