How this score was built
| Component | Weight | Earned | Why |
|---|---|---|---|
| Velocity | 55 | 5.1 | +6.0/wk, log-scaled against a 750/day ceiling |
| Acceleration | 15 | 8.9 | last week ran 1.59× the monthly pace |
| Freshness | 15 | 15.0 | last push 3d ago; decays to zero at 180 days |
| Scale | 15 | 9.9 | 2.6k stars, log-scaled against 150k — stops a 3-star repo topping the board |
| Momentum | 100 | 38.9 | sum of the above |
