Loading reported materials and source evidence.
Each property selection has its own source, conditions and result identity. Expand a value to inspect them. Observed and Computed describe the source report; catalogue eligibility and a clear anomaly check do not establish scientific validity. Different properties need not describe the same sample or state.
Missing pressure is not ambient pressure. Text structure claims remain separate from validated coordinates. A source-linked value does not override a material review hold. Source recovery candidates and external calculated references do not replace selected measurements.
Selection: legacy exact support. Catalogue property only, not a joint observation.

Unknown, not reported, reported false and not applicable are distinct states. A scoped negative report does not establish universal absence. Reported classifications are source assertions, not scientific approval or a joint Tc/state observation.

Each row is a retained extraction with its own conditions and source.
Tc type and lexical criterion remain separate retained fields.
Retained values and catalogue eligibility do not establish scientific approval. Operational anomaly checks flag records for review; no findings is not scientific validation. Repeated reports are not independent replications. Open each row’s review details or the retained-record Archive to inspect the supplied policy metadata.

Catalogue eligible — not scientific approval
Catalogue eligibility is a read-policy decision, not experimental confirmation or permission to use every property for ML.

Expand each extracted field for source context; these values are not used as catalogue headline selections or model-ready pairs.

Priors are assumptions for research context. They do not populate reported-property cells or classification filters, and are not observed labels for ML.
No priors supplied in this response.

Count: 0
Variation across Tc values or state metadata is not itself a scientific dispute.
Not detected by this check
Count: 0
An extraction inconsistency needs source inspection; it does not adjudicate the underlying physics.
No dispute report in this metadata
Count: 0
No report is not proof of consensus. An explicit dispute remains unadjudicated.
DOI, arXiv and catalogue identifiers may refer to the same work. Legacy paper links may include parent rollups or a different catalogue policy, so these counts need not match. Multiple occurrences or papers do not establish independent experimental replication, agreement, or scientific validity.
Count basis: bibliographic identifiers in assessed raw occurrences; legacy total papers can include parent rollups or other catalogue policy
