+# Web Research + GitHub + Website Coding Dataset
+
+Version: 1.1.0
+
+Total examples: 5,000,000
+
+## Splits
+
+- train: 4,750,000
+- validation: 125,000
+- test: 125,000
+
+## Core capabilities
+
+- Web search
+- Web research
+- Evidence extraction
+- Fact verification
+- Multi-hop research
+- Multi-layer technical analysis
+- Architecture analysis
+- Root-cause analysis
+- Security analysis
+- Performance analysis
+- UX analysis
+- Design analysis
+- Refactoring
+- Code review
+- Debugging
+- Website coding
+- Design systems
+- Developer experience
+- Developer onboarding
+- API developer experience
+- Documentation experience
+
+## Source diversity
+
+- Hugging Face: 20%
+- GitLab: 10%
+- Codeberg: 5%
+- Stack Exchange: 15%
+- MDN: 15%
+- PyPI: 10%
+- npm: 10%
+- Official web documentation: 10%
+- GitHub: 5%
+
+## Multi-layer reasoning structure
+
+Each deep analysis can cover:
+
+1. Problem
+2. Context
+3. Evidence
+4. Architecture
+5. Implementation
+6. Quality
+7. Security
+8. Performance
+9. UX
+10. Design
+11. Developer Experience
+12. Validation
+13. Trade-offs
+14. Final synthesis
+
+## Rate limits
+
+GitHub is intentionally limited to a small anchor pool.
+The 5,000,000 examples are generated locally from the collected
+source anchors and therefore do not require 5,000,000 API requests.
+
+## Data note
+
+The dataset consists primarily of generated examples grounded
+in public technical source metadata and URLs. It is not intended
+to be a bulk reproduction of third-party website contents.
