| Coverage | All seven sports now carry at least one sourced, class-matched anchor. Men's records are strongest; women's Muay Thai is the one remaining real gap (see Muay Thai, above). |
| Women's Muay Thai | Men's stadium records are well documented; women's class-by-class title counts are not. Need per-athlete verification before quoting a specific record. |
| Class mapping | App captures the user's division in kg/lb; some sourced facts are class-adjacent (e.g. "near your weight"). Decide how tight the match must be before it counts as "your class". |
| Reputation check | One exclusion already applied (Steven López, taekwondo). Every athlete should get a quick conduct check before shipping as proof. |
| Freshness policy | Confirmed direction: durable records only ("first to…", "most…", Olympic golds, retired legends). No "reigning champion" lines that decay. |
