## Useful for

- Run untrusted agent code in a MicroVM with a dedicated kernel
- Deploy a sandbox cluster via Terraform or Kubernetes
- Snapshot a running sandbox and roll back to it

## Why it’s here

- Star-counter measurements on 2026-10-29 (UTC), 00:08–15:27: 13074 → 13088 stars (+14). This is the change over that interval.
- Estimated end-of-day forecast: about +21 stars, using observed gains and the previous day.
- Over the last two days the pace is 1.8× that of the previous week and a half.

## Star trust

Star growth looks organic.

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

- Average over the last week: 13 per day
- Usual pace: 15 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.
