- examples/modules/ -> library/modules/ (top-level, no more symlink hacks in consumer projects) - compiler discovers stdlib via _NSGetExecutablePath / readlink /proc/self/exe; searches dev layout (../../library), install layout (../library), and alongside-binary fallback - SX_STDLIB_PATH env var overrides for tests / dev convenience - SX_DEBUG_STDLIB env var dumps the discovery results - build.zig installs library/ alongside the binary - Compilation gains stdlib_paths field threaded through resolveImports - 50 tests pass; consumer projects can now build from any cwd
