Vanilla Player#attack ends its successful-hit branch with causeFoodExhaustion(0.1F), and Block#playerDestroy calls player.causeFoodExhaustion(0.005F) for every block destroyed. Pumpkin never called add_exhaustion from either path: the only callers were the Hunger status effect in entity/living.rs and jump/sprint movement in entity/player.rs. Combat and mining were therefore free, so the hunger bar was effectively cosmetic for a player who was not sprinting. Player::attack now adds 0.1 exhaustion at the end of the hit path, after the damage_with_context early-return, so only hits that actually deal damage cost hunger. The Java and Bedrock block-break handlers now add MINE_BLOCK_EXHAUSTION (0.005) per block broken. Mining exhaustion is gated exactly where vanilla gates Block#playerDestroy: ServerPlayerGameMode#destroyBlock skips it in creative and when the block was broken without a tool that can harvest it, so the call sites reuse the existing can_harvest / block_drop checks rather than adding new conditions. Creative and spectator players are additionally covered by the existing abilities.invulnerable guard in Player::add_exhaustion, which mirrors vanilla Player#causeFoodExhaustion. Limitation: swimming exhaustion (0.01 per metre) is still missing. Player::progress_motion only implements the onGround branch of vanilla ServerPlayer#checkMovementStatistics; adding the swimming and in-water branches requires the whole else-if chain plus movement-state plumbing (Player::is_swimming is itself still an inferred approximation carrying a TODO), so it is deliberately left out of this change.
