• Improved Ranking — Faster recency decay tuned for fast-moving AI research, continuous engagement scoring, and centralized ranking weights for better calibration.

• Better arXiv Reliability — Merged category fetches to halve API calls, per-session request budget to prevent rate limiting, and cache-aware refresh that skips unnecessary fetches.
