I will run `pytest` to see if there are any existing unit tests in this project and check their current status.
### ftl_project_expert/cli.py:_load_env_file
VERDICT: CONCERN
CORRECTNESS: QUESTIONABLE
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: 
- **Encoding:** `open(path)` does not specify an encoding. It defaults to the system-dependent encoding, which will raise `UnicodeDecodeError` on non-UTF-8 default environments (such as some Windows environments) if the `.env` file contains non-ASCII characters. It should be explicitly opened with `encoding="utf-8"`.
- **Incomplete Exception Handling:** Only `FileNotFoundError` is caught. Other typical I/O exceptions such as `PermissionError` (if the file has incorrect permissions) or `IsADirectoryError` (if the path is a directory) are not handled and will crash the CLI. Catching `OSError` is much safer.
- **Inline Comments:** The parser does not handle inline comments. For example, a line like `API_KEY=12345 # production key` will parse the value as `"12345 # production key"`, which will break integration with downstream services.
- **Unverified Custom Parsing:** Naive hand-rolled env parsing is prone to failure with multiline variables or escaped quotes. Using a standard library approach or a robust parser is preferred, but at a minimum, unit tests should be added to verify these parsing constraints.

### ftl_project_expert/cli.py:cli
VERDICT: PASS
CORRECTNESS: VALID
SPEC_COMPLIANCE: N/A
ISSUE_COMPLIANCE: N/A
BELIEF_COMPLIANCE: N/A
TEST_COVERAGE: UNTESTED
INTEGRATION: WIRED
REASONING: 
- The `--env-file` option is successfully registered with Click with a default of `".env"`.
- Invoking `_load_env_file` within the group command ensures that `os.environ` is populated early. As a result, subsequent subcommands and their corresponding `envvar` option defaults will successfully resolve loaded keys.
- Integration is fully wired, but lacks automated test coverage.

### SELF_REVIEW
LIMITATIONS:
- Shell commands to run tests or search for additional test assets were blocked by execution policy.
- No specification or feature issue details were provided to cross-reference option design constraints.
---

### FEATURE_REQUESTS
- Ensure a read-only environment to run pytest/linters is available to verify changes.
- Provide existing test suites or test files in the observation context.
