More

• Philosophy — why banned-by-default, why self-validating, why Rust.
• Comparison — guardrail3 vs ArchUnit, clippy, cargo-deny, dependency-cruiser, ts-prune.
• Checks — what guardrail3 checks (config, source scan, dependency allowlists, apparch, release readiness, test quality, validation).
• Quick start — Rust and TypeScript bootstrap walkthroughs.
• Layout — active workspace layout and legacy archive.
• Thanks — primary inspiration, wrapped tools, and acknowledgments.
• Contributing — open a detailed issue first; PRs must pass the G3RS pre-commit gate.
