Checked all model class IDs (file names) against open issues. Found one match: issue #1486 ("Ecovacs GOAT A1600 LiDAR Pro Support") which explicitly mentions class e4gqia. That issue is resolved by the e4gqia.py symlink added in this PR — I've updated the PR description to close it. No other open issues were found for the remaining class IDs (3gwbbm, aadham, cgm9ex, m2nkyq, ss87ia, wwswjm).
