"""A Windows user imported the Tisusa .swarm (507 workspace files) and got an app card that said
"This app's files are missing" (2026-09-04). The staging reader keyed files with the OS separator,
the app importer looked for `workspace/`, skipped every file, and saved a hollow app. Bundle keys
are slash-separated everywhere now, and a bundle that ships files but none under workspace/ fails
loudly instead of importing a shell."""
