|---|---|---|---|
| Velocity | 55 | 8.7 | +1.9/day, log-scaled against a 750/day ceiling |
| Acceleration | 15 | 0.4 | last week ran 1.03× the monthly pace |
| Freshness | 15 | 14.9 | last push 3d ago; decays to zero at 180 days |
| Scale | 15 | 7.7 | 435 stars, log-scaled against 150k — stops a 3-star repo topping the board |
| Momentum | 100 | 31.7 | sum of the above |
