Struct FillExt 

pub struct FillExt {
    pub is_maker: u8,
    pub fee_1e9: i64,
    pub queue_ahead_1e8: i64,
}

Extended fill metadata (NOT in WASM memory — delivered via separate channel).

Provides additional context about a fill that doesn’t fit in the fixed-size Fill struct in WASM shared memory. Delivered out-of-band by the runtime.

fee_1e9: i64

Fee in 1e9 units. Negative = rebate.

queue_ahead_1e8: i64

Estimated queue depth ahead at time of fill (1e8 units), or -1 if unknown.
