Why this matters

EC2 metadata lookup should fail quietly. This is a good isolated test task with no product behavior risk.

Files to touch

• tests/app/remote/test_server.py

Exactly what to do

1. Add tests for _imds_token() when urlopen() raises URLError.
2. Add tests for _imds_get() when urlopen() raises TimeoutError or OSError.
3. Assert both helpers return None.
4. Keep the tests local and fully mocked.

Done when

• IMDS helpers have explicit coverage for the failure paths listed in the code
• No network is used in tests

python -m pytest tests/app/remote/test_server.py -q
