`INVALID_EVIDENCE_KIND`

HTTP 400

Something about the request must change

Evidence kind must be submission or verification.

How to fix it (contract guidance)

Use the documented evidence kinds.

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.
