Provenance Record

Well-structured News piece (663 words, within the 400-1200 word News range) using the standard Overview / What We Know / What We Don't Know format. Clear headline, accurate summary, logical flow from trial design to results to caveats. No AI self-reference, no promotional language, no defamatory content.

All 5 sources were checked. The chief:review script's local snapshots for source-2 (today.ucsd.edu), source-3 (technologynetworks.com), and source-4 (kpbs.org) contained real article content and were read in full from disk (gunzip + text extraction). Source-0 (nature.com, source-0.html.gz) and source-1 (pmc.ncbi.nlm.nih.gov, source-1.html.gz) returned HTTP 200 but the saved snapshots are bot-block/CAPTCHA challenge pages ('Client Challenge' and 'Checking your browser - reCAPTCHA' respectively) with no article content, despite the manifest recording no error. Per the skill's last-resort clause, I fell back to WebFetch of the live URLs and cross-checked with WebSearch (the WebFetch tool proved unreliable/inconsistent on this specific paper across repeated calls, so all its extractions were corroborated against an independent WebSearch query before being trusted). Verified via WebFetch+WebSearch: PhenoAge -4.9y/year p=0.004, PCGrimAge -3.1y p=0.007, GrimAge V2 -2.3y p=0.009, DunedinPACE -0.09 units (~9%) p=0.01, OMICmAge -2.2y p=0.009 (significant), RetroAge -2.2y p=0.030 (significant), Intrinsic Capacity clock not significant (p=0.31) -- all match the article exactly. Weill Cornell Medicine confirmed as a genuine co-author affiliation (via Alina P. S. Pang). The 'post hoc design, modest sample size, HIV-specific cohort, and 32-week follow-up limit generalizability' quote attributed to Nature Communications was confirmed verbatim via WebSearch indexing of the source text after an initial WebFetch pass gave inconsistent results. Publication date May 19, 2026 confirmed. today.ucsd.edu quotes (2) verified verbatim. kpbs.org quotes (3) verified: 2 verbatim, 1 ('would that snap back?') is a truncation of a longer quoted sentence ('...would that snap back, and then essentially they would be aging at the rate they were,') with the closing comma replaced by a question mark -- meaning is preserved, flagged as a minor style note only, not a correction. technologynetworks.com: the direct quote attributed to this source ('the key point is that this is the first randomized, placebo-controlled clinical evidence...') does NOT appear in the snapshot or the live page; independently confirmed via WebFetch of medicalnewstoday.com that Corley made this exact statement to Medical News Today instead. This is a wrong-outlet misattribution of a real, accurately-worded quote -- filed as a corrections record.

Every number, clock name, sample-size figure, and p-value in the article traces to the underlying paper and is independently corroborated by at least one secondary source (UC San Diego Today or Technology Networks). Co-author institution list is accurate. The one factual problem found is not in the data but in sourcing: one direct quote is correctly worded but attributed to the wrong outlet (Technology Networks instead of Medical News Today, which is not among the article's cited sources).

Substantively strong, accurately sourced News piece with one recoverable sourcing error (a real quote attributed to the wrong outlet). APPROVE_WITH_CORRECTIONS: publish with a public corrections record on the misattributed quote.
