## 2. Logic Chain
1. Using the `run_command` tool, we executed the targeted pytest coverage command: `.venv/bin/pytest --cov=reversecore_mcp/tools/malware/dormant_detector --cov-report=term-missing tests/unit/tools/malware/test_dormant_detector.py`.
2. Inspecting the stdout logged to `.agents/worker_m7_5_gen3/cov_output.txt` confirmed that `dormant_detector.py` has 77% coverage with 84 statements missed.
3. The specific missing lines were identified from the `Missing` column in the coverage table as: `20-21, 81, 89-97, 102-123, 149-152, 155-167, 207-210, 214-216, 252-257, 280-281, 327, 373-376, 591, 604-608, 615, 648-653, 660, 672, 702, 712, 731-732, 734-735, 767-772`.
4. Using the `run_command` tool again, we ran the full test suite command `.venv/bin/pytest tests/ -v`, redirecting output to `.agents/worker_m7_5_gen3/all_tests_output.txt`.
5. Running `grep_search` and viewing the summary of `all_tests_output.txt` revealed a total of 1838 tests collected, with 1771 passed, 64 skipped, and 3 failed.
6. The 3 failing tests are all located in `tests/unit/tools/analysis/test_signature_tools.py`.

## 3. Caveats
- Some tests were skipped (64 in total), which is normal for integration tests that require external tools (e.g., Ghidra, specific angr configurations, or radare2 under certain environments) that might not be fully configured in the local test run context.
- We did not modify any source code to fix the 3 failing tests, as the current mission was strictly diagnostic and reporting.

## 4. Conclusion
- `reversecore_mcp/tools/malware/dormant_detector.py` has a test coverage of **77%**, with the following lines remaining uncovered: `20-21, 81, 89-97, 102-123, 149-152, 155-167, 207-210, 214-216, 252-257, 280-281, 327, 373-376, 591, 604-608, 615, 648-653, 660, 672, 702, 712, 731-732, 734-735, 767-772`.
- There are exactly **3 test failures** in the entire project test suite, all in `tests/unit/tools/analysis/test_signature_tools.py`:
  - `TestGenerateSignature::test_success`
  - `TestGenerateSignature::test_invalid_address`
  - `TestGenerateYaraRule::test_smart_offset_search_failure`

## 5. Verification Method
- Execute the coverage command:
  `.venv/bin/pytest --cov=reversecore_mcp/tools/malware/dormant_detector --cov-report=term-missing tests/unit/tools/malware/test_dormant_detector.py`
- Execute the full test command to verify passing/failing status:
  `.venv/bin/pytest tests/ -v`
