Why this record matters
The phrase “brazilian martial artist” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q5240650. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1982, 2022, 2023 and 2024.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
