 **Notes:**
 - E35's crawler oracles (composer/go/nuget/python/maven) can't become `golden.rs` digests: their randomized trees use symlinks (no-ops on Windows), permission modes (ignored as root and on Windows) and case-colliding names (folded on macOS). The outputs therefore differ by OS and by uid, and a golden blessed in the root sandbox would fail on non-root Linux CI. Keep the oracles until a crawler can be checked without one.
