invalid session path

Error message

invalid session path

What it means

A generic InvalidInput guard raised while archiving a legacy work-state file: source.file_name() returned None, so the path terminates in '..' or is a filesystem root. The archive step needs a real file name to copy under, and cannot proceed without one.

Solutions

1. Pass a concrete file path (not a root or '..-terminated path) as the session source
2. Resolve the session path to a canonical file before invoking the archive/migration step
