`INVALID_ORDER`

HTTP 400

Something about the request must change

The reorder payload's order field failed validation.

How to fix it (contract guidance)

Send order as the array of workIds.

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/reorder
