`CONFLICTING_DEPENDENCIES`

HTTP 400

Something about the request must change

blockerIds and needs were both supplied and disagree.

How to fix it (contract guidance)

Send exactly one dependency field (prefer blockerIds).

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/batch
POST /api/items
PATCH /api/items/{workId}
