    - Run black formatter to fix formatting issues
    - Ensure consistent code style across all files
    - _Requirements: 3.2, 3.3_
  
  - [x] 4.3 Resolve type checking issues
    - Fix mypy type checking warnings and errors
    - Add missing type annotations if required
    - _Requirements: 3.2, 3.3_

- [x] 5. Validate and test fixes
  - [x] 5.1 Run complete quality check suite locally
    - Verify all ruff checks pass
    - Confirm black formatting is satisfied
    - Ensure mypy type checking succeeds
    - Validate all tests pass
    - _Requirements: 3.4_
  
  - [x] 5.2 Test workflow execution with fixes
    - Trigger manual workflow run to verify quality gates pass
    - Test package build process completes successfully
    - Verify PyPI authentication works in workflow context
    - _Requirements: 2.1, 2.2, 2.3_

- [ ] 6. Implement prevention system to block bad releases
  - [x] 6.1 Configure branch protection rules
    - Enable branch protection on main branch
    - Require CI workflow status checks to pass before merge
    - Require branches to be up to date before merging
    - Disable direct pushes to main branch
    - _Requirements: 4.1, 4.3_
  
  - [x] 6.2 Implement version synchronization validation
    - Add version validation step to publishing workflow
    - Extract and compare git tag version with pyproject.toml version
    - Fail fast with clear error message on version mismatch
    - Prevent PyPI upload conflicts from version desynchronization
    - _Requirements: 5.1, 5.2, 5.3_
  
  - [ ] 6.3 Create pre-release quality gate workflow
    - Create workflow triggered on tag creation attempts
    - Run same quality checks as publishing workflow
    - Block tag creation if quality checks fail
    - Provide clear error messages for failed checks
    - _Requirements: 4.2, 4.4_
  
  - [ ] 6.4 Test prevention system effectiveness
    - Attempt to create release with failing quality checks
    - Verify system blocks bad release creation
    - Confirm error messages are clear and actionable
    - Test version synchronization validation with mismatched versions
    - _Requirements: 4.5, 5.4_

- [ ] 7. Verify end-to-end publishing workflow
  - [x] 7.1 Test release-triggered publishing with clean code
    - Create test release from main branch with passing quality checks
    - Monitor workflow execution through all steps
    - Verify successful package upload to PyPI
    - _Requirements: 2.4, 2.5_
  
  - [x] 7.2 Validate publishing consistency
