Debug "Unknown" and "Conflict" archetype buckets in the metamage tournament DB, AND validate/invalidate archetype display names against community usage. Use when a meta-share chart shows an unexpected Unknown or Conflict slice, when classification accuracy regresses after a parser update, when adding/repairing archetype rules, or when an archetype's name looks wrong (suspected misnomer, suspected split/merge with another bucket). Distinguishes parser bugs (malformed decklists) from real classification gaps (missing aliases or rule overlap), validates archetype identity by comparing card-distributions between buckets and cross-checking against mtgtop8/MTGGoldfish/CardsRealm via the Exa MCP, and produces concrete JSON edits to MTGOFormatData rules.
