* test(javascript): reproduce TypeScript source dialect loss Add native directory/ASAR and built public CLI owners with actual locked native TypeScript syntax/emit and independent Babel source-range oracles. Production and every workflow remain unchanged. Signed-off-by: Rudy Celekli <rudy@gradiahq.com> * test(javascript): admit isolated native compiler inputs Use the actual TypeScript7 producer-requested --ignoreConfig flag when supplying isolated source filenames. Preserve every graph input, owning assertion, control and production file. Signed-off-by: Rudy Celekli <rudy@gradiahq.com> * fix(javascript): parse plain TypeScript artifacts without JSX Select the plain .ts dialect using the artifact source path so valid angle-bracket assertions retain syntax-derived graph facts. Preserve existing JSX defaults and all other dialects. Document the inert artifact parser contract.
