Canonical target directory. Nothing changed; show a trust dialog for exactly this string and, on accept, re-send with trust_accepted: true and trusted_directory echoing it verbatim. Safe to render verbatim in the dialog, by construction: every character is a visible, space-distinguishable glyph. Targets whose canonical path contains control (Cc), format (Cf), default-ignorable, line/paragraph-separator (Zl/Zp), non-ASCII-space Zs, or braille-blank code points are rejected (reason: unsafe_path) before this arm can carry them.
