Root + Impact

Description

placeBid emits emit AuctionSettled(tokenId, msg.sender, listing.seller, msg.value); before any settlement - code

AuctionSettled implies finalization — the event is emitted during normal bidding flow which is misleading for indexers and monitoring.

Recommended Mitigation

Remove or move this emit. Emit BidPlaced and AuctionExtended at the appropriate times; only emit AuctionSettled from _executeSale which is done already.
