/**
|
|
* Backup & Restore Tests — PM-5: encrypted backup/restore of ~/.waggle/
|
|
*
|
|
* Tests:
|
|
* 1. POST /api/backup returns an octet-stream file
|
|
* 2. Backup excludes marketplace.db and node_modules
|
|
* 3. Backup includes .mind files and config.json
|
|
* 4. POST /api/restore with preview mode
|
|
* 5. POST /api/restore applies restore successfully
|
|
* 6. Restore rejects corrupted/invalid files
|
|
* 7. Backup → restore round-trip (backup, restore to same dir, verify)
|
|
* 8. Backup without vault key (unencrypted fallback)
|
|
* 9. Restore with wrong encryption key fails
|
|
* 10. GET /api/backup/metadata returns metadata after backup
|
