September 12, 2025: Foundation: ranked battles, friends, practice, and replay.

New

  • The first public product foundation combined ranked battle UI, ELO movement, forfeit handling, timers, and result screens.

Changed

  • Friends, invitations, notifications, and public profile viewing gave the arena a social loop instead of only solo practice.

Fixed

  • Practice filtering, AI analysis panels, match replay, and opponent solution display established the early evidence loop.

Why it matters

  • The launch surface set the product contract: real input-based work, competitive pressure, and reviewable feedback.
