//! `ados-camera-probe` — boot-time apply-verify-auto-revert oneshot for the
//! CSI camera overlay.
//!
//! Runs once per boot (a systemd oneshot, gated by `ConditionPathExists` on
//! `/etc/ados/camera.probation`) to confirm the sensor the overlay was applied
//! for, or restore the pre-overlay boot config when nothing bound. The whole
//! decision lives in [`crate::camera_probe`]; this binary wires
//! logging and the default real paths.
