What the opposite direction is quoted right now
Opposite direction
2.60 bp
Moves away from the reference, captures nothing, quoted at the floor.
Spread of 4.80 bp between two swaps a volatility-driven hook would quote identically. Both figures above are computed from the drift the hook itself reports. test/integration/DynamicPricing.t.sol pins the property on chain: in one block, against one reference, the swap capturing the drift is quoted strictly higher than the swap adding to it.

These are the real event signatures from IAssayEvents.sol, populated with the quote above — a preview of what this swap would emit, not a log fetched from the chain. Every SwapAssayed event the pool has actually emitted is read from the chain and listed on the markets page. sender is the router, never the trader.
