## Why it’s here

- Star-counter measurements on 2026-10-07 (UTC), 05:52–07:18: 71 → 85 stars (+14). This is the change over that interval.
- Estimated end-of-day forecast: about +58 stars, using observed gains and the previous day.
- The repository is 3 days old and already has 85 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.
- Top new repositories this week: #141.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
