XFS: o teste com exclusão real mostra o que funciona de verdade

No CI, com um XFS apagado pelo kernel, a recuperação por metadados não acha nada (o kernel zera
o inode e as extensões); o carving recupera o conteúdo de arquivos com estrutura reconhecível.
O teste de nome e pasta fica ignorado até o Guará ler o diário, e o roadmap e a documentação
passam a dizer isso em vez de marcar o XFS como validado.

 In a single scan, Guará does what tools like Recuva, PhotoRec, TestDisk and Disk Drill do separately:
 
-- **File system metadata:** finds deleted files **with name, folder and date** on NTFS, FAT12/16/32, exFAT, ext2/3/4, HFS+, Btrfs, XFS and APFS.

 - **Encrypted volumes:** opens BitLocker, LUKS and FileVault 2 with your password or key and scans inside.
 - **RAID and LVM:** reassembles arrays from loose disks (RAID 0, 1, 4, 5, 6, 10, LVM2), working out level, stripe size and order by itself when there is no metadata.

 - **Overwritten data does not come back.** On an SSD with TRIM the disk may zero deleted blocks; Guará warns you, but it cannot work miracles.
 - **Fragments:** only JPEG (up to three pieces) and MP4 without an index are reassembled. Other formats, if fragmented, come out truncated with low confidence.
 - **ReFS and Storage Spaces** are not supported (ReFS is only detected).
-- **APFS:** no free-space map. **XFS and APFS:** deletion recovery tested only in simulation.
+- **XFS:** on a real XFS (v5, kernel deletion) the inode and its extent list are wiped, so Guará recovers the **content** of files with a recognizable structure by carving, but not their name or folder; reading names needs the file system journal, which is not implemented. The old inode-based path only works on simulated deletions. **APFS:** deletion recovery tested only in simulation.
 - **NTFS:** compressed files, EFS and heavily fragmented records are skipped or marked as incomplete.
 - **exFAT:** validated with a synthetic image; real media are still missing.
 - **Phones:** Guará works with storage media and does **not** unlock devices or bypass passwords.
