## [1.0.2] - 2025-06-23

### Changed

- **File naming convention**: Updated filenames to use zero-padded sequence numbers (0001, 0002, 0003, etc.) while keeping titles with simple numbers (1, 2, 3)
- **Template header formatting**: Added bullet points for bold items in header sections to prevent them from appearing on one line
  - Date and Status now display as `- **Date:** ...` and `- **Status:** ...`
  - Applied to both default and simple templates

### Added

- **New formatting functions**:
  - `formatSequenceNumber()` for titles and display (returns 1, 2, 3)
  - `formatSequenceNumberForFilename()` for filenames (returns 0001, 0002, 0003)
- **Comprehensive documentation**: Created missing `docs/USAGE.md` with detailed usage guide covering:
  - Complete command reference with examples
  - Template system documentation
  - Linking strategies and best practices
  - File organization and naming conventions
  - Troubleshooting guide
  - Advanced usage scenarios

### Fixed

- **File searching**: Updated `findReportByNumber()` functions in both `new.ts` and `link.ts` to correctly search for files using zero-padded format
- **Test coverage**: Updated tests to verify both filename and title formatting functions work correctly

### Technical

- Separated sequence number formatting logic for better maintainability
- Enhanced test suite with additional formatting verification
- Updated documentation to reflect new filename patterns

## [1.0.1] - 2025-06-22

### Fixed

- Fixed README documentation for simple template description to accurately reflect that it follows the full 8D structure (D0-D8) with streamlined content, rather than having completely different sections.
