Use a marked metadata-only directory for both Cargo target and intermediate outputs, reject native targets and output/config overrides, and keep Cargo.lock fixed. Preserve peer scripts while preventing stub files from entering ordinary build caches. Add ten behavior regressions to Preview preparation; these tests record commands and do not substitute for native CI.
