Evidence
Source checking verifies the cited claim or transcription. It does not establish independent reproduction.
Evidence table
Inspect claims, sources and review details
Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.
One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.

- review
- method: source-hash-verification; ai-assisted-source-review; reviewer: claude; reviewer note: Extractor: Claude research agent for the issue #88 follow-up. Reviewer: separate Claude review agent, independent of the extractor; no human review claimed; date: 2026-10-11; artifact sha256: c40f09ae30a945394aef0aac37d331982df0e89fa00f2f290505124dfc4f7bdb; retrieval url: https://www.ebi.ac.uk/europepmc/webservices/rest/search?query=DOI%3A%2210.1186%2Fgb-2014-15-3-r46%22&format=json&resultType=core; method note: Re-downloaded the artifact three times, compared its SHA-256 with the pin, read the title, DOI, authors, abstractText and licence field, and read the licence statement in the article full text (Europe PMC PMC4053813 fullTextXML).; note: Re-downloaded on 2026-10-11: three retrievals gave the same bytes (c40f09ae...), which do not match artifact_sha256 (5209b274...). No saved copy of the pinned retrieval exists, so the difference cannot be inspected; hash_scope says these responses are not byte-stable. The fresh record is MED/24580807, PMC4053813, DOI 10.1186/gb-2014-15-3-r46, Wood DE and Salzberg SL, Genome Biology 15(3), 2014, and its abstractText contains both passages quoted in changes.md.
