| 20 | ## Analysis Dimensions |
| 21 | |
| 22 | | Dimension | Checks | |
| 23 | | ---------------------- | ---------------------------------------- | |
| 24 | | **Feature Coverage** | Whether all documented features have corresponding tests | |
| 25 | | **Path Coverage** | happy path / error path / edge case | |
| 26 | | **Layer Coverage** | Unit / Integration / E2E | |
| 27 | | **Module Coverage** | Service / Provider / Controller / Entity | |
| 28 | |
| 29 | ## Coverage Gap Classification |

| 31 | | Level | Definition | Risk | |
| 32 | | --------------- | ------------------------------- | ------ | |
| 33 | | 🔴 Critical | Core logic has no tests | High | |
| 34 | | 🟠 Major | Important branches have no tests | Medium | |
| 35 | | 🟡 Minor | Edge cases have no tests | Low | |
| 36 | | ⚪ Nice-to-have | Optional additional coverage | - | |
