+
+Actuation is implemented in `computer-use/portal-input.js`, `computer-use/actuator.js`,
+`computer-use/safety.js`, `computer-use/audit.js`, `skills/computer-act.js`, and
+the local portal/AT-SPI helpers. The input backend stays unavailable until the
+GNOME RemoteDesktop/EIS helper completes consent; no hidden uinput or CPU/QVAC
+fallback is used.
 
 Exit gate: Night Light, Text Editor save, Firefox URL entry, hands-off abort,
 and lock-screen kill pass `docs/cu-acceptance.md`.
