# AirDef headless simulation

This package compiles the same `airdef-mod/src/sim` source as the game adapter, with `glam` as its only dependency. A checkout does not need the Horizon submodule to build or run it:

```sh
cargo test --manifest-path airdef-core/Cargo.toml
cargo run --manifest-path airdef-core/Cargo.toml --release --example sim_run -- --list
cargo run --manifest-path airdef-core/Cargo.toml --release --example sim_run -- --scenario big-smart
```

The shared scenario harness runs for both packages. Adapter integration tests for layout and smoke stay in `airdef-mod`; `core_boundary` verifies the public type facade and deterministic combat trace.

This is an incremental boundary: the simulation still produces rendering and audio declarations and formats some UI text. Moving those outputs and diagnostics to adapters, remain follow-up work. The mod re-exports `airdef_core::sim` as its existing public facade.
