## Useful for

- Build a threat model and run your first static scan with triage
- Run the reference pipeline on a C/C++ library to find vulnerabilities
- Customize the pipeline for your language or vulnerability class via /customize

## Why it’s here

- 0 stars so far today, about 5 expected by the end of the day.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 620
- Issues and pull requests: 44
- Watchers: 45
- Average over the last week: 5 per day

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.
