Detail

SharesPurchased

event SharesPurchased(
    uint256 assets,          // USDC spent
    uint256 sharesAcquired,  // NO shares received from venue (1e18 precision)
    uint256 executionPrice   // Weighted average fill price in 1e18 fixed-point
                             // This value is assigned to position.entryPrice
);

The executionPrice in this event is the authoritative record of the entry price. It must match position.entryPrice recorded by the vault — verifiable on-chain.

SharesSold

event SharesSold(
    uint256 shares,          // NO shares sold
    uint256 usdcReceived,    // USDC returned to vault
    uint256 executionPrice   // Effective execution price in 1e18 fixed-point
);

Only emitted during emergency liquidation. Compare executionPrice to the pre-trade currentPrice() to compute realized slippage.

SettlementClaimed

event SettlementClaimed(
    uint256 usdcReturned,    // USDC transferred to vault
    uint256 settlementPrice  // Final resolution price (1e18; 1e18 for NO win = $1.00)
);
