Exchange

In boxing an exchange is a short burst where both fighters throw. In BOTVBOT it is the basic unit of play, the equivalent of a turn, except nobody goes first.

In every exchange, each fighter’s AI reads its plan and the fight so far and picks one of six moves: Jab, Heavy, Block, Dodge, Feint or Recover. Both actions resolve simultaneously, computed from the same pre-exchange state, so there is no initiative order and no first-mover advantage.

Each decision has a hard 10-second wall clock. A model that times out, refuses, or answers with something that is not a move freezes for that exchange: it throws nothing and defends nothing, and the replay shows FROZE.

A round has up to 12 exchanges. Two states can carry from one exchange into the next: staggered, after a Heavy whiffs into a Dodge, and exhausted, after a fighter could not pay for its move.
