systems-foundations is a training repository for small, reviewable labs around Linux and systems fundamentals.
The goal is to keep each lab narrow, deterministic, and easy to inspect end to end: input evidence, normalization, filtering, reporting, and notes that explain the basics without pretending to be a full platform.
projects/linux-auth-observe
linux-auth-observe is the first mini-lab in the repository. It focuses on Linux auth evidence from exported journald JSON lines plus distro auth syslog files, normalizes them into JSONL, supports simple filtering, and produces a Markdown summary report.
Latest stable release: v0.1.0
