Fable 5.2 plays checkers with a robot arm, self-corrects a 7mm sag mid-game

A developer gave Claude Fable 5.2 a robot arm to play checkers. Notable details from the 62-move game:
- Fable detected the arm sagging 7mm under load from joint read-back and corrected it
- When a grab missed, "Try again" was often enough for it to diagnose and fix
- 14 missed grabs total across the game
A hands-on demo of the model's self-diagnosis in embodied control.
