Module close_code 

Session close codes: the WebTransport session close, the WebSocket close frame.

Constants

FORBIDDEN

A 403 refusal: the provider forbade the caller, or a re-authentication named a different principal. The {id: 0, err} frame before the close says which.

PROTOCOL

The control stream broke protocol: first frame not Init, a frame that does not decode, or a frame over the size limit.

SERVER_ERROR

The AuthProvider could not decide (a 5xx: its key server is down). Not a verdict on the credentials: retry later, do not sign out.

TOO_MANY_SESSIONS

Too many open sessions for this principal.

UNAUTHENTICATED

Authentication was refused (401), or no Init arrived in time. A refusal is preceded by an {id: 0, err} frame; a timeout is not.
