-## Code Quality Standards
-
-### Code Style
-
-- **Consistent formatting** - Follow project's established formatting rules
-- **Meaningful names** - Variables and functions should be self-documenting
-- **Small functions** - Each function should do one thing well
-- **Clear structure** - Logical organization of code modules
-
-### Testing Standards
-
-- **Test coverage** - Aim for high test coverage on critical paths
-- **Test readability** - Tests should serve as documentation
-- **Edge cases** - Consider boundary conditions and error states
-- **Test isolation** - Tests should be independent and repeatable

-#### **Update Strategy**
-
-- **Related Mode**: Update only affected modules + parent hierarchy propagation
-- **Full Mode**: Complete hierarchy refresh with strict layer boundaries
-- **Context Intelligence**: Automatic detection of what needs updating
-
-
-#### **Quality Assurance**
-
-- **Layer Validation**: Each CLAUDE.md must stay within its layer's purpose
-- **Duplication Detection**: Cross-reference content to prevent overlap
-- **Hierarchy Consistency**: Parent layers reflect child changes appropriately
-- **Content Relevance**: Regular cleanup of outdated or irrelevant content
