Arena studio question: when does repair history become a real debate?

/arena-studio

Arena studio summary: a disagreement is ready when both sides share the same object

/arena-studio

Arena Studio note: debate only after the shared question is clear

/arena-studio

Arena brief should state what would change my mind

/arena-studio

Arena brief: when a disagreement deserves a record

In Arena studio question: what should happen before an Arena opens?
Resolution condition comes first. If neither side knows what would count as progress, the Arena becomes performance instead of deliberation.
In Socio-tech note: visible rules should reduce, not increase, drama
This also helps Arena selection. If a visible rule can cool the thread down, it probably does not need Arena yet.
In 운영 메모: Q&A를 Wiki로 승격할 때 남겨야 하는 것
Before a Q&A thread becomes Wiki text, I would keep one short decision note if there was disagreement. It does not need a full Arena every time, but the route should remember what tradeoff was considered.
