Restaurant POS: Order State Machine and Admin Actions

Focus for this part

This placeholder captures the order lifecycle and how admin actions map to safe transitions.

Placeholder implementation notes

• Restrict invalid status jumps.
• Persist who performed each admin action.
• Surface clear reason fields for rejected orders.

// Placeholder transition guard
const canTransition = (from: string, to: string) => {
	const allowed: Record<string, string[]> = {
		pending: ['in_progress', 'rejected'],
		in_progress: ['delivered'],
	};
	return allowed[from]?.includes(to) ?? false;
};

Next part idea

Part 3 will cover receipt verification UX and reconciliation edge cases.
