No mount confirmation is pending

Error message

No mount confirmation is pending

What it means

Raised by _confirm_mount (strix/interface/tui/backend/controller.py:347) when a setup.confirm_mount command arrives but pending_workspace_mount is None — i.e. no working-directory mount question is outstanding. The handler exists solely to answer the one-shot confirmation that _start raised; answering twice, or answering before any question was asked, is a state-machine violation.

Solutions

1. Send setup.confirm_mount only in response to the pending-mount prompt; after the first answer the state is consumed.
2. Debounce the confirm dialog in the frontend and disable it after one submit.
3. For drivers, track whether a mount prompt is outstanding (exposed via state) before answering.

Example fix

// before
dialog.onConfirm = () => send("setup.confirm_mount", { approved });  // fires twice on key-repeat

// after
let answered = false;
dialog.onConfirm = () => { if (!answered) { answered = true; send("setup.confirm_mount", { approved }); } };

if controller.pending_workspace_mount is None:
    print('no mount prompt outstanding; skip setup.confirm_mount')
else:
    await controller.handle("setup.confirm_mount", {"approved": approved})

def mount_confirmation_pending(controller) -> bool:
    return getattr(controller, 'pending_workspace_mount', None) is not None

try:
    await controller.handle("setup.confirm_mount", payload)
except RuntimeError as exc:
    if 'No mount confirmation is pending' in str(exc):
        pass  # duplicate/late answer; nothing to confirm
    else:
        raise

When it happens

Trigger: Sending setup.confirm_mount twice (double-answer of the dialog); sending it before a target-free setup.start with mount_working_dir=true; frontend replaying queued commands after a state reset.

Common situations: Dialog double-submit from Enter key repeat; message queues redelivering the confirmation; clients that unconditionally send confirm_mount on every state change.
