# `omena-engine-input-producers`
Internal Rust crate for input-derived producer artifacts built from `EngineInputV2`.
This crate is the current Rust producer boundary inside the repo. It owns:
- family-level producer artifacts for `expression-semantics`, `source-resolution`, `expression-domain`, and `selector-usage`
- top-level lane artifacts for `source-side` and `semantic`
- canonical-candidate bundles, evaluator-candidate bundles, and canonical-producer signals where the input contract preserves enough evidence
Current lane calibration:
- unrestricted canonical lane:
- `expression-semantics`
- `source-resolution`
- `source-side`
- `semantic`
- bounded canonical lane:
- `expression-domain`
- evaluator coverage is intentionally limited to type-fact-backed corpora
- shadow-only lane:
- `selector-usage`
- current `EngineInputV2` does not preserve enough reference-level evidence to promote it beyond shadow validation
Primary checks:
- `cargo test --manifest-path rust/Cargo.toml -p omena-engine-input-producers`
- `pnpm check:rust-source-side-lane`
- `pnpm check:rust-semantic-lane`
- `pnpm check:rust-producer-boundary`
Release-facing bundle:
- `pnpm check:rust-release-bundle`
This crate is intentionally internal. `publish = false` remains in effect at the workspace level.
