   The Hedera investigation page is factually solid overall, with all 16 atomic claims confirmed or partially supported. The four partially-supported findings involve minor inaccuracies: the ATH date is off by one day (Sep 16 not Sep 15); the 'full mainnet shutdown' language overstates what was actually a proxy access restriction; the DAI token attribution in the exploit is stated by Hedera but not independently corroborated by the Pangolin post-mortem; and the '70% decline by end of Q1 2025' claim overstates the pace of decline (price was roughly 50-55% off peak by March 31, 2025). No claims were found to contradict reputable current sources, and no link rot was detected on checked URLs.

   All 16 reviewed claims were either confirmed or partially supported — zero claims were disputed by the reviewer. The four partially-supported findings (claim_findings[2], [6], [10], [13]) involve minor peripheral inaccuracies: a 1-day ATH date error, a proxy-vs-full-mainnet characterization nuance, an unconfirmed DAI token attribution, and a ~50-55% actual Q1 decline versus the stated 70%. None of these concern core allegations of fraud or security. No link rot or stale citations were detected. One high-priority coverage gap on HBAR regulatory status is noted and warrants expansion in a future revision, but an open coverage gap does not warrant denial or revision under current policy.
