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 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.
