# Handoff Report - Milestone 5 Format Fixes (memory_tools.py coverage)

## 1. Observation
We observed the following regarding the target file `tests/unit/tools/common/test_memory_tools.py`:
- Running `black --check tests/unit/tools/common/test_memory_tools.py` returned exit code 1 with:
  ```
  would reformat tests/unit/tools/common/test_memory_tools.py
  Oh no! 💥 💔 💥
  1 file would be reformatted.
  ```
- Running `ruff check tests/unit/tools/common/test_memory_tools.py` returned exit code 1 with 3 lint errors:
  ```
  W293 [*] Blank line contains whitespace
     --> tests/unit/tools/common/test_memory_tools.py:508:1
  W293 [*] Blank line contains whitespace
     --> tests/unit/tools/common/test_memory_tools.py:511:1
  W293 [*] Blank line contains whitespace
     --> tests/unit/tools/common/test_memory_tools.py:533:1
  ```
- The target tests passed initially under `pytest tests/unit/tools/common/test_memory_tools.py -v` (29 passed).

## 2. Logic Chain
- To resolve formatting and lint errors, we must run standard project tools to reform and clean the code in the target file.
- Executing `black tests/unit/tools/common/test_memory_tools.py` reformatted the file.
- Executing `ruff check --fix tests/unit/tools/common/test_memory_tools.py` resolved all 3 fixable W293 violations.
- Repeating both checks confirms that:
  - `black --check tests/unit/tools/common/test_memory_tools.py` now returns exit code 0 ("1 file would be left unchanged").
  - `ruff check tests/unit/tools/common/test_memory_tools.py` now returns exit code 0 ("All checks passed!").
- Running `pytest tests/unit/tools/common/test_memory_tools.py -v` verifies that the formatting/linting changes did not introduce regressions, as all 29 tests continue to pass.

## 3. Caveats
- No caveats. Only the target test file was formatted and linted; no underlying application code logic was modified.

## 4. Conclusion
The file `tests/unit/tools/common/test_memory_tools.py` is now fully compliant with Black formatting and Ruff code quality rules. All tests run and pass cleanly.

## 5. Verification Method
Verify that formatting, lint checks, and tests pass by running:
1. `black --check tests/unit/tools/common/test_memory_tools.py`
2. `ruff check tests/unit/tools/common/test_memory_tools.py`
3. `pytest tests/unit/tools/common/test_memory_tools.py -v`
