ADDED Requirements

Requirement: Game state transitions are always applied atomically

The system SHALL always apply the complete returned state from action functions and never discard intermediate state updates.

Scenario: Betting round completion state is preserved

WHEN completeBettingRound returns a new state with advanced currentTurn and reset bets
THEN the game applies the entire returned state, including turn advancement and bet resets, even if the betting round stage does not change

Scenario: Action function results are never lost

WHEN a player performs any action (check, call, raise, fold, all-in)
THEN the returned state from the action function is applied completely before any subsequent processing occurs

Requirement: Player controls are disabled during AI turns

The system SHALL disable human player input controls while AI players are taking their turns to prevent race conditions.

Scenario: Human clicks during AI turn

WHEN an AI player is processing their turn (400ms delay) and the human player clicks a bet control
THEN the action is rejected, the UI shows disabled controls, and no state mutation occurs

Scenario: Controls re-enable after AI turn completes

WHEN an AI player completes their action and the turn advances to the human player
THEN the bet controls become enabled and the human player may act

Requirement: Validation is enforced before applying any action

The system SHALL validate all actions against game rules before applying state changes, returning unchanged state for invalid actions.

Scenario: Invalid raise is rejected

WHEN a player attempts to raise below the minimum raise amount
THEN the action is rejected, the state remains unchanged, and an error reason is returned

Scenario: Fold always permitted

WHEN a player attempts to fold during any betting round, including pre-flop
THEN the action is accepted regardless of current bet level

Requirement: Pot distribution preserves all chips

When awarding pots to winners, the system SHALL distribute all chips without losing remainder amounts.

Scenario: Odd pot split between two winners

WHEN the pot contains 105 chips and two players tie for the win
THEN one winner receives 53 chips, the other receives 52 chips, and zero chips are lost

Scenario: Single winner receives full pot

WHEN a single player wins the pot of 200 chips
THEN the winner receives exactly 200 chips and the pot is reset to 0
