Longitudinal Health Record (LHR) Architecture

OverviewCopy Anchor Link

This directory contains the comprehensive architecture documentation for transforming the current encounter-focused Careplan system into a full-featured Longitudinal Health Record (LHR) system.

Key Design Principle: Extend existing functionality rather than replacing it, ensuring 100% backward compatibility and zero workflow disruption.
