Prevent replay payout after admin resolution.
resolve_game pays immediately, then persists a Completed game with a winner. The public payout path accepts that same state/winner and can call process_payout again, draining other funds if the contract has enough token balance. Add an explicit paid/settled guard, or make process_payout reject when both player escrow deposits are no longer present.
🛡️ One minimal guard in process_payout
// Deduct both stakes first (clean state, prevents double-spend)
let player1_escrow = escrow.get(game.player1.clone()).unwrap_or(0);
+ if player1_escrow < game.wager_amount {
+ return Err(ContractError::InsufficientFunds);

The external test module mod test; (line 1059) is not guarded with #[cfg(test)], unlike the inline mod tests block at line 793. While test.rs itself starts with #![cfg(test)], explicitly guarding the module declaration in lib.rs is clearer and matches the pattern used elsewhere in this file.

Test does not actually verify admin-only authorization or final game state.
Two gaps in a test that the PR summary claims verifies "authorization scoping" and settlement:
env.mock_all_auths()on line 348 unconditionally approves everyrequire_authin the transaction. The test never exercises a non-admin caller invokingresolve_game, so the admin-only guard is not actually covered. A companion negative case (e.g.try_resolve_gamefrom astrangerwith per-address auth mocks, expectingErr) is needed to back up the PR's "authorization scoping" claim — analogous to howtest_configure_fees_permissioned(lines 292–316) pairs a success path with a stranger-rejected path.- Only token balances are asserted. The core contract-side effects of
resolve_game— transitioningGameState::Completedand recordingwinner = Some(player1)— are never read back from storage. If a future refactor accidentally skipped the state/winner update but still produced a correct payout, this test would silently pass.
Suggested additions
// After resolve_game:
env.as_contract(&contract_id, || {
let games: Map<u64, Game> = env.storage().instance().get(&GAMES).unwrap();
let game = games.get(game_id).unwrap();
assert_eq!(game.state, GameState::Completed);
assert_eq!(game.winner, Some(player1.clone()));
});
// And a separate test:
#[test]
fn test_resolve_game_rejects_non_admin() {
// ...setup identical up to create_game/join_game...
let stranger = Address::generate(&env);
// Use per-address auth mocks instead of mock_all_auths so the admin
// requirement is actually checked.
let res = client
.mock_auths(&[/* stranger only */])
.try_resolve_game(&game_id, &player1);
assert!(res.is_err());
