Design Notes

Design Notes document the reasoning behind specific design choices, trade-offs, implementation details, and lessons learned during the development of a system or subsystem.
They complement architecture entries by providing deeper insight into the decision-making process and capturing the engineering rationale behind real-world decisions.
Each Design Note is a standalone entry and typically includes:

• context and problem statement
• design options considered
• trade-off analysis
• chosen solution
• implementation notes
• verification strategy
• lessons learned
  The goal is to provide engineering-grade documentation that exposes how and why technical decisions are made.
