## Movement harness — shared types and MovementModule concept.
## Mirrors gun_interface.nim structure.

import gun_harness/gun_interface

export gun_interface.WorldState

type
  MoveCommand* = tuple[speed: float, turnRate: float]
    ## speed: target speed in px/tick, clamped to ±8 by bot API
    ## turnRate: body turn rate in degrees/tick

## MovementModule concept — any type T implementing computeMove is valid.
template isMovementModule*(T: typedesc): bool =
  compiles(
    block:
      var m: T
      let ws = WorldState()
      let cmd: MoveCommand = m.computeMove(ws)
  )
