+/**
+ * @brief Run the recurring UART evidence stream for the isolated CTF image.
+ *
+ * Initializes the standard I/O subsystems, anchors the quarantined dispatch
+ * frame in flash memory, evaluates the frozen telemetry against the compiled
+ * safety threshold, prints the startup banner, and repeatedly emits the
+ * system status report every second.
+ *
+ * @param None.
+ * @return int Standard exit code (never reached in normal firmware execution).
