Override CORE::GLOBAL::symlink and CORE::GLOBAL::link so that calling the builtins on mocked paths works within the mock filesystem. symlink($target, $link_path): - Converts a non-existent mock into a symlink pointing to $target - Fails with EEXIST if destination already exists - Passes through to CORE::symlink for unmocked paths link($source, $dest): - Copies contents and metadata from source mock to destination mock - Follows symlinks on source (matching Perl's link() behavior) - Fails with EPERM for directories, EEXIST if dest exists - Documented limitation: writes to one don't propagate to the other Both functions are registered in file_arg_position_for_command for strict mode support.

S_IFLNK (0120000) and S_IFREG (0100000) share bit 0100000, so a bare `$mode & S_IFLNK` test matches regular files too. This caused contents() to return undef for all file mocks, breaking 23 test files. Use `($mode & S_IFMT) == S_IFLNK` — the same pattern is_dir() and is_file() already use correctly.
