Yep. Open weights is closer to having precompiled binaries only (though you can do a little bit more with open weights). All training data with labeling, plus a detailed build log including any special fine-tuning logs, is needed, especially to help show how the final weights were arrived at (since there can be randomness involved). Unless someone else can both replicate your final output plus make their own changes to it, it's not fully open source.
