Start by running the reported termux-clipboard-set and termux-clipboard-get loop while Termux is in the background on Android 14. Investigate the termux-clipboard-get entry point and Android background clipboard behavior; done means the command returns the current clipboard content in that scenario, or the limitation is clearly documented.
