FAROL and the official list of CIn research groups
The site describes FAROL as an agentic AI research group founded in 2025 by two professors at UFPE's Center for Informatics. The Center's official list includes 41 groups, and FAROL is not among them — MusTIC and Voxar Labs are. The affiliation with CIn belongs to the two people who coordinate the group.

The credit on the Hello World album
The press page lists Giordano Cabral's name on the 2018 album Hello World, composed with the Flow-Machines system. The official credits page separates artists, research team and acknowledgments: he appears in the third list, alongside Jean-Pierre Briot and Geber Ramalho, not in the first two.
Only one source states that he participated in the album's development: an article dated June 15, 2023, from CESAR, the institution he chaired at the time. Daccord states that the Brazyle database is used in the Flow Machines project; no source links it to the album.

The Instituto Caldeira Technical and Scientific Council
The institute does not publish the membership of the council, created in April 2026, and there is no public record naming him as a member. The information is supported by his CV and private correspondence, which readers cannot verify. On September 23, 2026, the address institutocaldeira.org.br returned a permanent redirect to a domain that does not resolve; the organization's record remains accessible in Mapa das OSC.

The role in Florescendo Talentos
The career history published on the homepage describes him as a lead researcher since 2025. The public source is Stanford Impact Labs, which lists the investment Preparing Brazil's Youth and names him under Team, with the role Chairman of the Board, CESAR School. The description of his technical role came from his CV.

The Turma do Som animation studio
Lattes lists 27 educational animated videos produced between 2010 and 2012 for Turma do Som, Daccord's music education platform. No public source describes the team that produced them or states that he set up a studio for this purpose. There is also no series called Turma da Música: the series is Turma do Som. What is publicly available is the presentation of the platform by educational consultant Cecília Cavalieri França on June 5, 2012.

The work with Samsung on extended reality
Requested for inclusion on the site, but not included. The search on September 18, 2026, covered Lattes, the web and the project dossiers and found only private material: it is a user experience research effort conducted by Voxar Labs with a team from SiDi, unrelated to extended reality. The institutional partnership between CIn/UFPE and Samsung has been public since 2005 and does not mention him.

The five startups mentioned in the bios
Public bios mention five technology-based startups. Three are documented in public sources — Daccord Music Software, MusiGames Studio and Escribo — and the site counts three.

Figures that differ across sources
The size of Arena das IAs
The site uses 124 models, always with a cutoff date of July 22, 2026. The archive itself publishes three counts: 121 on a help page, 122 at launch and in the g1 report, and 124 at the close. Only 124 is consistent with the 5,797 predictions and the statement about 121 of the 124. The number of models in Série A appears as 10, 11 and 12 on three screens of the same site; until a source resolves the discrepancy, the site does not give a figure for Série A.

Daccord's figures
The site repeats four figures that the company publishes about itself: 116 countries, 4 million uses, 450 titles in its catalog and 30 partner brands. None is recent — the About Us page already listed the 116 countries and 4 million uses in June 2016, and the 450 titles and 30 brands in May 2022. These are figures reported by the company, without an external audit.

The 2012 Finep Innovation Award
The win was in the Northeast regional round, in the Small Business category, among 81 entries from the region. The list of twelve winners of that year's national round, published in Finep's own magazine, does not include the company — which also described its 2009 and 2012 wins as regional.

The chairmanship of the Comissão Especial de Computação Musical (Special Committee on Computer Music)
The site records his leadership of SBC's CECM for the 2017–2019 term, and the commission's 2019 minutes place his leadership in that term. SBC's institutional page records his leadership for the 2022–2023 term, with Filipe Calegário as deputy, and lists no term for 2017–2019. Both statements come from the commission itself, and the site does not choose between them.

The Arsenal of Tools item count
On September 17, 2026, version 3.7 was observed to contain 507,785 items; on September 18, 2026, the same version reported 320,483 on its homepage. The site publishes both figures and the date of each observation because the database is not stable.
The Mapa da Fluência Agêntica question bank
Two counts for the same database: 264 items in the v0.3.0 master database and 330 questions on the overview page. They represent different stages of the same work, and no source says which describes the database today.

Publications from 2024 to 2026
The site publishes its list of bibliographic works from Lattes, where the most recent entry is from 2023. The CV was updated on August 19, 2026, and lists no articles, chapters or conference papers from 2024, 2025 or 2026. Other work appeared during the same period: the dossier on AI in Brazil in ActuIA No. 16, dated July 16, 2024, with Jean-Pierre Briot and Fabio Cozman; the bylined article in Grit Daily on December 15, 2023; the talk at TEDxBoa Viagem ED on July 22, 2025; and the open tools released in 2025 and 2026.

Citations on Google Scholar
The site publishes citation counts from Semantic Scholar and OpenAlex, along with the date they were retrieved. Google Scholar figures could not be obtained: the profile exists and belongs to him, but the citations page returned a CAPTCHA on every attempt, including two automated browser runs on September 18, 2026. Total citations, h-index and i10 remain blank.
Playing Açude on PsyFun Platform
The game's information page opens and describes a match: five rounds of fifteen seconds, about five minutes, three computer-controlled opponents. The button leading to the match points to an address that returned 404 on September 23, 2026, as it had on September 18, 2026; the source code repository linked in the footer also returns 404. The game has been announced and is not yet playable.
