Update Protocol

This file is maintained by both humans and AI agents. When updating:

  1. After completing a component: Change its bar and percentage
  2. After adding a component: Add a new row in the appropriate section
  3. After architectural changes: Update the ASCII diagram
  4. Date: Update the Last updated comment at the top of this file

Progress bars use: █ (filled) and ░ (empty), 10 characters wide. Percentages: 0%, 10%, 20%, ... 100% (in 10% increments).
