# WebDAV MKCOL — namespace isolation
# ═════════════════════════════════════════════════════════════
# WebDAV requests are isolated per-user by `resolve_webdav_path`
# (webdav_handler.rs:189). If the requested path doesn't begin
# with the caller's home folder name ("My Folder - <username>"),
# the handler silently prefixes the caller's home folder path
# onto the front. Effect: any WebDAV path a client sends is
# always resolved INSIDE the caller's own tree, regardless of
# what they wrote.
#
# These tests assert the isolation works (regression guard) and
# that the service-level verify_owner still acts as
# defense-in-depth for the legitimate path.


# ─────────────────────────────────────────────────────────────
# Step 16 – Bob crafts a path that looks like it targets admin's
#            home. The WebDAV handler rewrites the path to live
#            under bob's home, so the request succeeds (201) but
#            the new folders land in BOB's tree — never admin's.

#              sub-folder name inside bob's tree).
