From 3808b226674a60e0e01c580c6f4e90d705d5c560 Mon Sep 17 00:00:00 2001 From: 22314621 Date: Sat, 16 May 2026 20:23:34 +0300 Subject: [PATCH 1/2] fix: add 30s grace period for 1v1 ranked disconnect wins (BUG-05) Previously, a momentary WiFi blip would instantly declare the opponent as winner in 1v1 ranked games. WinCheckExecution checked isDisconnected() every ~1 second, with no reconnect window. Changes: - Track disconnectGraceTick when only 1 of 2 humans is connected - Winner declared only after 300 ticks (30 seconds) elapse - Grace timer resets if the disconnected player reconnects - Both-disconnected edge case handled (most tiles wins after grace) 4 new tests cover: immediate, expired, reconnect, both-disconnect --- src/core/execution/WinCheckExecution.ts | 61 ++++++- .../core/executions/WinCheckExecution.test.ts | 161 ++++++++++++++---- 2 files changed, 184 insertions(+), 38 deletions(-) diff --git a/src/core/execution/WinCheckExecution.ts b/src/core/execution/WinCheckExecution.ts index 8b86643539..a5e0776c13 100644 --- a/src/core/execution/WinCheckExecution.ts +++ b/src/core/execution/WinCheckExecution.ts @@ -23,6 +23,14 @@ export class WinCheckExecution implements Execution { // maxGameDuration hard kill. 170mins (10 mins before 3hrs) private static readonly HARD_TIME_LIMIT_SECONDS = 170 * 60;
