 * that matters: a developer who links their working checkout into the cache
 * would otherwise have it deleted on exit by a name match alone.
 *
 * The cache root itself must not resolve through a symlink either. When
 * `~/.cache/opencode` is a link to `~`, comparing realpaths makes the whole
 * home directory "inside the cache" and containment proves nothing.
