A ZIP archive can have readable metadata and still contain paths that escape, collide, or change under another platform's filename rules.
PathParcel is a local metadata preflight that does not extract. It reports traversal and absolute paths, reserved Win32 names and characters, case-insensitive collisions, collisions under documented .NET Windows replacement behavior, file/directory prefix conflicts, symlink metadata, and central/local path disagreement.
It does not inspect compressed content, malware, link targets, permissions, authenticity, decompression behavior, the destination filesystem, or a particular extractor. A clean report does not establish archive safety.
