How to read these data

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.

Tc max

—Selection unresolved

Selection unresolved. A legacy catalogue value is not substituted without its contributing result.

Retained result available; origin or selection remains unresolved.

Selection: none. Catalogue property only, not a joint observation.

Notes: legacy origin pool untraceable · legacy summary has no exact source support

Retained source results (1)

These are retained proposals, not public-eligible headline selections. Some may require anomaly review; numerical display does not approve them for scientific use.

Reported classifications and mechanism evidence

Reported classifications, priors and support

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.

Current reported-property projection; inspect individual evidence before reuse.

Each row is a retained extraction with its own conditions and source.

Tc type and lexical criterion remain separate retained fields.

How to read these records

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.

Retained Tc (K)	Record origin / role	Review	P (GPa)	Sample	Method	Pairing	Year	Source tier	Paper
21Criterion not supplied	Unknownprimary source role	Review details Policy: anomaly-review/1.0.0. No findings is not scientific acceptance. A format issue means the parser or metadata needs review, not that the physics is impossible. Result: legacy-result:4f1a14facf60f4f4b9953197cf3277f023d85fbd114c392704ad3206af2aa401 Operational references are review triggers, not physical upper limits. Values are not clipped or replaced by this display; source corrections require separate evidence-backed revision.

Catalogue eligible — not scientific approval

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