## 🔴 High Priority Issues

### H-001: Component Test Generation - Hyphen Handling
- **Issue**: Generated test function names contain hyphens, causing Rust compilation errors
- **Status**: ✅ RESOLVED
- **Resolution Date**: September 3rd, 2025
- **Description**: Test generation script created function names like `test_date-picker_component_exists()` which is invalid Rust syntax
- **Root Cause**: Component names with hyphens not properly sanitized for Rust function names
- **Solution**: Updated test generation script to replace hyphens with underscores in function names
- **Files Affected**: `scripts/generate_component_tests/src/main.rs`
- **Prevention**: All test generation functions now use `safe_name = component_name.replace('-', "_")`

### H-002: Playwright Configuration - Incorrect Web Server Path
- **Issue**: Playwright config references non-existent `book-examples/leptos` directory
- **Status**: ✅ RESOLVED
- **Resolution Date**: September 3rd, 2025
- **Description**: E2E tests failing due to web server startup failure
- **Root Cause**: Hardcoded path in `playwright.config.ts` pointing to wrong directory
- **Solution**: Updated path to `examples/leptos` which contains the actual Trunk project
- **Files Affected**: `playwright.config.ts`
- **Prevention**: Path validation in CI/CD pipeline

### H-003: Main Package Dependencies - Missing Avatar Component
- **Issue**: `leptos-shadcn-ui` package cannot compile due to missing `leptos-shadcn-avatar` dependency
- **Status**: ✅ RESOLVED
- **Resolution Date**: September 3rd, 2025
- **Description**: Main package compilation fails when trying to publish due to missing avatar dependency
- **Root Cause**: Avatar component added as dependency but not available as workspace member or published crate
- **Solution**: Temporarily removed avatar dependency from main package features
- **Files Affected**: `packages/leptos-shadcn-ui/Cargo.toml`
- **Technical Debt**: Avatar component needs to be properly integrated or published

### H-004: Test Generation Script - Format String Arguments
- **Issue**: Generated tests contain unused `component_name_pascal` variables in format strings
- **Status**: ✅ RESOLVED
- **Resolution Date**: September 3rd, 2025
- **Description**: Compilation warnings about unused variables and incorrect format string usage
- **Root Cause**: Test generation templates reference variables not used in actual format strings
- **Solution**: Removed unused variable assignments and cleaned up format string arguments
- **Files Affected**: `scripts/generate_component_tests/src/main.rs`
- **Prevention**: Template validation and automated testing

### H-005: Component Discovery - Non-Component Directory Processing
- **Issue**: Test generation script attempts to process non-component directories like `.storybook` and `utils`
- **Status**: ✅ RESOLVED
- **Resolution Date**: September 3rd, 2025
- **Description**: Script fails when encountering directories that don't contain Leptos components
- **Root Cause**: No validation of directory contents before processing
- **Solution**: Implemented `valid_components` whitelist to filter only actual component directories
- **Files Affected**: `scripts/generate_component_tests/src/main.rs`
- **Prevention**: Directory validation and component detection logic

### H-006: Avatar Component Implementation - Leptos Macro Usage

- **Root Cause**: Status command not querying the actual component registry
- **Solution**: Modified to dynamically fetch component counts from `shadcn_registry::registry_ui::UI`
- **Files Affected**: `packages/cli/src/commands/status.rs`
- **Prevention**: Integration testing between CLI commands and registry

### H-008: Test Utils Compilation - Borrow Checker Errors
