Test Case: Shared trusted xattr

Test ID: TC070-shared-trusted-xattr Fixture: basic.erofs, /trusted-shared-a, /trusted-shared-b

Objective

Verify a shared Linux trusted.* entry through FreeBSD extattr semantics. The transformer must record e_name_index: 1 -> 4 for the shared record.

Manual steps

lsextattr system /mnt/repo22-g4/trusted-shared-a
getextattr -qq -x system trusted.config /mnt/repo22-g4/trusted-shared-a
getextattr -qq -x system trusted.config /mnt/repo22-g4/trusted-shared-b
su -m nobody -c 'getextattr system trusted.config /mnt/repo22-g4/trusted-shared-a'

Expected results

Root receives trusted-shared-value from both files. FreeBSD exposes the full trusted.config name in namespace system, not a namespace named trusted. The unprivileged system-namespace request is denied. Clean up the mount/md.
