strategy_feeder — DRIVE racket op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.strategy_feeder(side: 'int', ctx: 'dict', rng, step: 'float' = 0.06) -> 'dict' (to call the implementation directly, import racket; racket.strategy_feeder(side: 'int', ctx: 'dict', rng, step: 'float' = 0.06) -> 'dict'; from the registry, opsdrive.get("strategy_feeder"))

Usage

Returns the ball to a position close to the previous one but slightly shifted (a ball easy for the opponent to take): moves its own previous aim by a uniform random ±step and keeps it inside the court (12 cm from the edge). Flight time is a slow 0.42 s.
