Pipeline notes

The summary and note below are generated by the signal pipeline — they are Beyond Desk’s reading, not quotations from the source.

Kern is a 1.5MB Rust-based container and resource runtime with no daemon, using OCI images, cgroup v2, and namespaces. It sets CPU/RAM limits and starts isolated tasks in ~3.5ms, targeting CLI and agent use cases as a lighter alternative to Docker.

A working zero-daemon container runtime tuned for agent and CLI isolation, with concrete size and startup claims. Worth checking if Docker's overhead doesn't fit your workflow.
