`CROSS_PROJECT_FOLD`

HTTP 400

Something about the request must change

foldedInto must reference an item in the same project.

How to fix it (contract guidance)

Fold only within one project's board.

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/items/{workId}/state
