Research direction

Start with src/meridian/config.py and locate the environment variable mappings and decimal validation. Find the existing tests for configuration loading, then add coverage for each mapping, a non-numeric tolerance, and environment values overriding file values. Done means every mapping has a test; run the relevant pytest tests.
