Deep source code teardown of DeerFlow

[NeuZhou]

We read through the DeerFlow codebase and wrote a detailed technical analysis as part of Awesome AI Anatomy -- source code teardowns of 11 AI agent projects.

DeerFlow teardown: https://github.com/NeuZhou/awesome-ai-anatomy/tree/main/deer-flow

Things we highlighted:

• The 14-layer middleware architecture is the cleanest separation of concerns we found
• Hash-based loop detection (warn at 3, kill at 5) is a pattern more projects should adopt
• The orphan tool call bug fix (93 lines) likely affects every LangGraph-based agent

If anything is inaccurate or missing context, feedback is welcome.
