`ANONYMOUS_WORKSPACE_ALREADY_CLAIMED`

HTTP 409

Something about the request must change

This anonymous workspace was already claimed by an account. This code is retained for historical receipts and is no longer emitted.

How to fix it (contract guidance)

Use INVALID_ANONYMOUS_TOKEN recovery guidance for current claim requests.

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.
