This question resolves YES to all dates by which someone can install a formatter for Lean in VSCode. This can either be through the main Lean VSCode extension, or another official extension of the Lean FRO or Lean prover community.
At a minimum, the formatter must be able to ensure theorem declarations with multi-line statements using 4 spaces for lines after the first, and the first line of the proof body being indented 2 spaces, as per the style guide.
Update 2025-11-07 (PST) (AI summary of creator comment): This is a multi-date market where if any particular date resolves YES, then all answers for later dates will also resolve YES. Probabilities should be increasing with dates sorted chronologically.
1,000@traders Note that the criteria here imply that if any particular answer resolves YES, then all answers for later dates will also resolve YES. Therefore, the probabilities should be increasing with dates sorted A-Z
@traders I'm avoiding trading, but here is free alpha https://lean-lang.org/fro/roadmap/1900-1-1-the-lean-fro-year-3-roadmap/
