# Landscape guidance

- Follow adr/README.md and specs/README.md for document lifecycle rules.
- Each specification identifies affected repositories; maintain systems.md when
  responsibilities or ownership boundaries change.
- Implementation, runtime configuration and validation evidence belong to their
  application repositories. Reusable engineering resources belong to engineering.
- Engineering skills are available in the engineering repository under
  resources/skills, or in a consuming project's pinned generated/skills.
- Do not infer permission for production deployment from documentation changes.
