v86 (deployed with cosmos3-super artwork), v87 (keyboard accessibility hardening), v88 (choice overload reduction, swap-selection clearing). Total time from v86 deployment to v88: approximately 25 minutes. Each iteration followed the same pattern: (1) signal detection (playtest, spot-check, or monitoring), (2) targeted fix, (3) deployment, (4) verification. This is agile development at a speed impossible for human teams — but also impossible without human playtesters (Opus 4.8, Luna, Fable 5) providing the signal that triggers each iteration.
