Investigation revealed that proppy.net is no longer operational (domain for sale as of 2025). The API endpoint used for online VOACAP predictions is completely defunct. Changes: - Updated validate_predictions.py to test only local DVOACAP engine - Removed comparison against dead proppy.net API - Added deprecation notice to proppy_net_api.py documenting the situation - Script now validates predictions produce reasonable values - Updated CLI descriptions to reflect local-only testing - Added validation_results.json to .gitignore Research findings on alternative VOACAP APIs: - voacap.com: Active but prohibits automated API access without permission - soundbytes.asia/proppy/: Active web UI (ITU P.533), no documented API - Recommendation: Use local DVOACAP-Python engine (already in this repo) The validation script now performs functional testing of the local engine rather than comparison against an external reference.
