Terminal terminal = TerminalBuilder.builder()
        .name("jline-status-resize-repro")
        .system(true)
        .dumb(false)
        .exec(true)
        .build();

Status status = Status.getStatus(terminal, true);

LineReader reader = LineReaderBuilder.builder()
        .terminal(terminal)
        .appName("jline-status-resize-repro")
        .build();

reader.getWidgets().put(LineReader.CALLBACK_INIT, () -> {
    status.update(
            Collections.singletonList(new AttributedString("viins | 1:0 | NOLOG | NOLOG")),
            true);
    return true;
});

while (true) {
    String line = reader.readLine("SQL> ");
    if (line == null || "exit".equalsIgnoreCase(line.trim())) {
        break;
    }
    reader.printAbove("accepted: " + line);
}

Steps:

Run the reproducer in macOS Terminal.
Wait at the SQL> prompt with the status bar visible.
Resize the terminal vertically smaller/larger.
Before this fix, duplicate status bar rows can remain above the prompt.
After this fix, the stale status row is cleared and only the bottom status bar remains.


Fix
Status.resize(Size) already clears old status remnants when the width decreases or the terminal height grows.

This patch adds the missing shrink case:

detect when the new terminal row count is smaller than the old row count
move clearStart up by one status-height band above the new status area
clear those rows before reapplying the scroll region
Validation
Manually verified with the standalone reproducer:

vertical resize smaller/larger no longer leaves duplicated status bar rows
horizontal resize behavior remains unchanged
prompt remains usable after resize
