How this score was built
| Component | Weight | Earned | Why |
|---|---|---|---|
| Velocity | 55 | 0.0 | −1.0/wk, log-scaled against a 750/day ceiling |
| Acceleration | 15 | 0.0 | needs 7-day and 30-day rates side by side |
| Freshness | 15 | 2.1 | last push 5mo ago; decays to zero at 180 days |
| Scale | 15 | 7.6 | 412 stars, log-scaled against 150k — stops a 3-star repo topping the board |
| Momentum | 100 | 9.7 | sum of the above |
