## Update Protocol
80+
81+
This file is maintained by both humans and AI agents. When updating:
82+
83+
1. **After completing a component**: Change its bar and percentage
84+
2. **After adding a component**: Add a new row in the appropriate section
85+
3. **After architectural changes**: Update the ASCII diagram
86+
4. **Date**: Update the `Last updated` comment at the top of this file
87+
88+
Progress bars use: `█` (filled) and `░` (empty), 10 characters wide.
89+
Percentages: 0%, 10%, 20%, ... 100% (in 10% increments).
