  "abstract": "Scientific data are routinely transformed so they can be stored, joined and used by machine-learning models. These steps enable scale, but they can also remove the context that tells us what a prediction means and how far it can be trusted. Metal–organic frameworks (MOFs) make this problem especially clear: one nominal material may appear as an experimental crystal, an activated simulation structure, a charge-assigned model or a row of descriptors, while information about protonation, counterions, coordination environment or measurement conditions may disappear along the way. We introduce claim readiness: a framework for asking whether the evidence preserved through a data pipeline is sufficient for the scientific claim made at the end of it. By tracing chemical evidence, identifier joins and evaluation choices, we show that data can be highly usable for machine learning yet incomplete for chemistry-sensitive interpretation, and that a model can still be useful for ranking candidates even when its value-level accuracy decreases under a harder split. The wider lesson is not specific to MOFs: trustworthy scientific machine learning requires a traceable connection between the representation used by the model and the evidence needed to support the resulting claim. Highlights • Claim readiness matches scientific claims to evidence preserved in data pipelines • Model-ready materials data can lose chemistry needed for interpretation • Data joins change which materials enter representation comparisons • Harder data splits reduce accuracy while useful candidate ranking can remain",
