# Implementation Diagram Notes

This folder contains handbook-only implementation diagram examples and guidance.

## Rules

- Keep Mermaid source as canonical.
- Prefer plain Mermaid fenced blocks in step notes for Obsidian rendering.
- Avoid wrapping Mermaid with HTML containers (`<details>`, `<summary>`, `<div>`, etc.).
- Store run-specific outputs under `plans/<run-id>/implementation/`.
