This is not full-season coverage.
- Corroborated first-party appearances supplement missing archive game logs. Existing archive appearances are not replaced; conflicting statistics remain separate.
- Native player IDs equal jersey numbers in every audited observation; event IDs are placeholders. Neither establishes career identity.
- Source player totals that fail reconciliation are withheld independently of validated team totals and complete plays; they never enter player aggregates.
- Validated NCAA plays replace conflicting archive PBP only for independently corroborated repaired games. Original archive observations remain retained.

- Secondary NCAA-derived acquisition; not directly retrieved from NCAA.
- Player identities are source player-season records, not proven longitudinal athlete identities.
- Coverage requires exact game corroboration and independent score, identity, participant and clock checks.
- Current rating exclusions: {"Non-Division I participant": 547, "Terminal PBP score disagreement": 15}.
- 2010 player coverage is sparse because most source player IDs are missing.

- Roster artifacts span 2003–2026; published career links cover corroborated seasons only. Historical NCAA-derived player logs begin in 2010; validated native ESPN boxes supplement 2004–2009. No 2003 game passed validation. Supplemental play-by-play is unavailable. Player-box captures for 2003–2004 are sparse.
- Conflicting athlete GUIDs are quarantined; players are never joined by name alone.
- Cross-provider links require at least two distinct matched games, both-team final score/overtime agreement and exact individual-statistic matches. Supplemental ESPN logs use verified native athlete IDs, with no name-only identity join.
- Observed team associations do not establish transfer transaction dates.
