Tombstone an edge whose endpoints the effective subject owns. Idempotent.Edges carry no reliable owner of their own, so ownership is proven by
requiring the subject to own both endpoint nodes. Removal writes a tombstone
rather than deleting the row, mirroring node forget, so the removal stays
auditable and reversible while graph reads filter the edge out. An edge the
subject cannot fully see returns 404.
This route requires the memory:forget scope. A key carrying write also qualifies.A missing or invalid credential returns 401 authentication_error. A valid credential without the scope returns 403 permission_denied, and the problem body names the exact scope required.
Ownership is proven by both endpoints. Edges carry no reliable owner of their own, so the effective subject must own the source node and the target node. An edge you cannot fully see is 404.
This is a tombstone, mirroring node forget, so it is auditable and reversible in the graph read paths.
