  - Granularity handling and edge cases (out-of-bounds periods)

- **period_id.py:** 9 tests covering `PeriodId` value object
  - Token-based immutability pattern
  - Equality, hashing, and string representations
  - Slot-based attribute restrictions

- **utils.py:** 14 tests covering utility functions
  - `to_datetime()` for date/datetime conversion
  - `calculate_digits()` for digit calculation
  - `count_time_units()` for time span counting (all granularities)

## Execution Environment

- **Python:** 3.14.3
- **pytest:** 9.0.2
- **pytest-cov:** 7.1.0
- **Polars:** 1.39.3

## Directives Compliance

✅ All test directives followed:

1. **Interface + Results Testing:** All tests verify both that methods return correct types AND that the computed values match specifications
2. **make_calendar_table:** Tests verify first, middle, and last period records with full content validation
3. **make_period_id:** Tests verify encoding correctness, including out-of-bounds period handling and decoding consistency
4. **get_period_range:** Tests verify tuple components match period bounds across all test scenarios
5. **100% Coverage Target:** Achieved—all executable code paths are exercised

## Conclusion

The test suite provides **comprehensive validation** of the `artip` module's functionality.
All 70 tests pass successfully with **100.0% code coverage** (statements + branches),
ensuring robust implementation of temporal period encoding for Power BI Vertipaq integration.

All directives have been met. The codebase is production-ready.
