Create or replace one attribute (admin)

The body's key must be the path's. default_set_ids must name sets this firm already holds AND holds under this attribute (422 otherwise, naming the set and both attributes): a default set of another attribute renders nothing on every matter that inherits it. The position is the server's and a body's is accepted and ignored: a new key goes one past the firm's last, and a key the firm holds keeps its place. On a row the connector owns or has bound, label and proposed are the firm's and the rest, position aside, is the connector's: a body that differs from the stored row in any other field is a 409 naming the fields, because the connector declared them and its options and sets are written by the sync. On any other row a body that says source: connector, or carries a binding the row does not already have, is a 409: both are set by connecting a practice system, never by a write.
