 ## Next steps toward full GitHug parity
 
 - Replace the fallback in-memory Git engine with a packaged native Git binary
-- Expand real repository-backed level validation beyond `init`, `add`, and `commit`
-- Port all original levels and hints into structured content files
+- Tighten advanced real repository-backed validation across the full Githug catalog
+- Continue refining per-level setup fidelity for the remaining advanced scenarios
 - Add richer validation rules and per-level explanations
 - Add onboarding, accessibility polish, icons, tests, and Play Store assets
