Constant COMPUTER_NOTES_DISPLAY_KEY 

pub const COMPUTER_NOTES_DISPLAY_KEY: &str = "computer_notes";

Reserved display_payload key carrying the short notes a native computer call returns beside its screenshot (a new tab, a dialog, an HTTP error, a batch that stopped early). The executor also writes them into its result text for engines that read text; a provider that replays them apart from the screenshot reads them from here, so no provider parses the text layout. Only the result data is read for this key, never the call’s arguments. Not a scalar, so it has its own bounded entry in tool_display_payload.
