Matching yamux errors with errors.Is was too broad. Session.close hands every live stream ErrStreamReset wrapped around whatever killed the connection, so a keepalive timeout, a broken TCP connection or a peer that simply vanished all matched, and a relayed request that died reported a clean ending. Nothing upstream would have retried or logged it. Match the plain sentinels by identity, since only identity separates a stream that was reset from the wrapped form that means the session died. Treat a StreamError as a per-stream reset, and a GoAwayError as normal only when it carries the no-error code, read off ErrRemoteGoAway because the constant is unexported. ErrSessionShutdown needs no entry of its own; it is a GoAwayError with that code. Order matters as much as the matching: session death wraps its cause, which is routinely io.EOF or a closed socket, so the mux checks run before the generic endings. Reversing them alone puts a vanished peer back to nil. Assisted-by: Claude Opus 5 [claude-code] Signed-off-by: Ettore Di Giacinto <mudler@localai.io>
