👋 Thanks for the contribution! A few things to tighten up before this is ready for review:

• PR description is missing. Please add a description that explains what changed, why it changed, and anything reviewers should pay attention to. The PR checklist in CONTRIBUTING.md has a handy template.
• Branch prefix: The guidelines suggest feat/(short-description) — feature/research is close but feat/weekly-research would be more consistent.
• Scope question: At +1,189 lines this is a meaningful addition — if it's a larger feature, it may help to open an issue first to align on scope before the full implementation lands.

Happy to look again once those are addressed! 🙂
