nocter-native-session

Responsibility

Compose a successful compiler session with Target, MIR, Machine, ARM64, and Mach-O lowering and return a complete native artifact or typed failure.

Contract

The crate orchestrates existing stage contracts and owns output bytes plus native test execution support. It does not implement source-language checks, backend rules, command-line policy, or filesystem publication transactions.

Invariants

• Each stage consumes exactly the previous closed product.
• A backend integrity failure cannot be presented as a source-language diagnostic.
• Partial native output is never returned as a successful artifact.
