# Add DevIndex Spider Engine Guide

- Create a new guide at `learn/guides/devindex/spider/Engine.md`.
- Document the `Spider.mjs` service, detailing its "bottom-up" discovery strategies (Network Walker, High Stars, Keyword, Temporal, Community/Stargazer) and the rationale behind finding "Hidden Whales".
- Include a section on Strategy Evolution to explain how weights changed as the index grew.
- Include a Mermaid sequence diagram illustrating the architectural flow.
- Document resilience mechanisms: Backpressure Valve, Rate Limit Monitoring, and Checkpointing.
- Update `learn/guides/devindex/tree.json` to include the new `Spider Engine` guide.

**Input from Gemini 3 Pro:**

> ✦ I have created the `Engine.md` guide. It includes the strategy evolution details, the Mermaid diagram for the architectural flow, and the resilience mechanics as discussed. The file has been committed and pushed to the repository. Closing the issue now.
