Description
- 式の評価やアクションの実行とどう違うのか
- エラボレーションでは何をしているのか
たとえば、再帰的な定義から自己参照を取り除いて recOn 系で書き換える処理はエラボレーション中に行っている。
パース時ではないし、マクロ展開中でもない。

Research direction
No file or test is named in the issue. Start by investigating Lean's elaboration phase and compare it with parsing, macro expansion, expression evaluation, and action execution, using the recursive-definition-to-recOn transformation as the concrete example. Done means the documentation clearly answers what elaboration does and how it differs from those phases.
