- Score history charts (30/90/365 day views)
- Methodology page explaining scoring system
- Initial compare page structure
- React Query (TanStack v5) integrated for server state
Scoring Engine (Phase 1 complete)
- Composite score (0–100) calculation pipeline
- Adaptive weights per technology category and maturity
- Multi-window EMA momentum tracking (7/30/90 days)
- Bayesian smoothing to prevent noise-driven volatility
- A-F confidence grade system based on data completeness
Data Sources (first batch)
- GitHub API integration (stars, forks, issues, contributors)
- Hacker News, Dev.to, RSS feed aggregation
- Stack Overflow API integration
- npm download statistics
��� State at This Point
- No AI layer yet
