Macro include_generated_models 

macro_rules! include_generated_models {
    () => { ... };
}

Include $OUT_DIR/generated_models.rs produced by valence_codegen::build.

Expands to a generated module plus pub use generated::*. Invoke once at crate root (or another module that should re-export models):

valence::include_generated_models!();

Schema DSL files under schemas/ are scan inputs for codegen; they are not linked via mod. The generated module must be linked into the binary so inventory registrations are visible.
