trade8 Rust SDK

The shared vertical plane: fixed-point Price/Qty math, protocol codecs, the event contracts (order/fill/print), and typed clients - consumed by every trade8 service and by external integrators as a pinned git tag.

use trade8_sdk::math::PriceQty;
use trade8_sdk::events::{OrderAccepted, FillExecuted};

What's in the plane

Import path	Role
trade8_sdk::math	fixed-point Price/Qty arithmetic (no float drift)
trade8_sdk::events	the order/fill/print event contracts
trade8_sdk::clients	typed clients over the service APIs
trade8_sdk::strategies	strategy harness contracts for backtesting

Why a shared plane

Every trade8 service links the same math and contracts - a fill reported by Router, journaled by Desk, aggregated by Pnl, and drawn by eTrader carries bit-identical numbers end to end. The SDK plane is the single source of that truth (SDD's shared-plane linkage boundary keeps it a {vertical}-sdk, not dissolved per-service crates).
