The audit trail design is what stands out here. Every code suggestion traces back to the exact line in the note it came from instead of just showing a confident-sounding output, and signed notes are amended with new versioned entries rather than edited in place. That's the right instinct for something that ends up as a legal record. HIPAA compliance being part of the base plan instead of an enterprise upsell also matters for smaller practices that can't go through a procurement cycle just to document a visit safely.
