Good catch! So "because" of cut, if there is any cyclic notation (even not used in current sequent), we just can't determine provability of given sequent. Right?
Indeed, there is probably nothing safe to say regarding provability checks with both cuts and cyclic notations.
The provability check make the turnstile red in: https://click-and-collect.linear-logic.org/?s=&n=a%2C%3Fa%5E While there is a proof.
