- Split builtin lowering into focused API owners and keep module dispatch separate.
- Share byte conversion, receiver checks, and filesystem option parsing; remove redundant forwarding and clarify names.
- Preserve compiler output and diagnostics, with import boundaries enforced by the code-quality checks.
- Separate function signatures, argument completion, specialization, and body construction from call dispatch.
- Share generic binding checks, argument prologues, return completion, and native input validation.
- Enforce direct implementation imports while preserving existing ABI and diagnostic behavior.
- Derive builtin call names from shared signatures and keep call semantics with their ABI contracts.
- Separate runtime dependency detection, exception metadata, and library policy from the core IR while preserving existing exports.
- Enforce the frontend signature boundary and validate native compilation and policy behavior.
- Enforce oxlint and oxfmt for owned JavaScript and TypeScript with independent CI checks.
- Preserve compiler import boundaries and protected fixtures while cleaning up lint findings.
- Standardize source formatting and validate import, fixture, and embedded-source protections.
