wickra-gym v0.2.0

wickra-gym v0.2.0 — a deterministic, Gymnasium-compatible, microstructure-aware backtest environment with O(1) steps: the dataset is precomputed once into a fixed feature tensor, so every step() is a pure array index for fast, reproducible RL rollouts. Native Rust, Python (a real gymnasium.Env), Node.js, WASM plus a C ABI hub for C, C++, C#, Go, Java, R — every binding produces byte-identical trajectories.
